Let’s begin with where this thermal and power efficiency is visually demonstrated. The GPU is responsible for pushing millions of pixels to your display and does so up to 60 times each second. During gameplay it is called upon to render 3D worlds in ultra-realistic detail, all while the CPU may calculate the artificial intelligence of the game characters or the physics of the explosion you just caused. All these high performance tasks could make other SoCs burn a lot of power, and generate a great deal of heat. Snapdragon SoCs have a history of being cooler than the competition.

Mobile devices have a very different set of thermal constraints. In the archaic PC segment, desktop computers are housed in large enclosures and are cooled by thick metal heat-sinks with a large and often loud fan. In contrast, mobile devices are mere millimeters thin and are expected to be held in your pocket, your hand, or against your cheek. There are certain thermal thresholds that must be met for a handheld to be a viable product. Skin temperature is one of them. If the devices’ thermal threshold is surpassed, the SoC begins to throttle back its frequencies, and thus performance, in an effort to reduce the heat. This can have negative impacts on performance and overall user experience. 

\n

OEMs’ design decisions are able to help mitigate some of this heat. The proximity of high power components and the material used in the phone to dissipate the heat are some of the methods employed. Qualcomm Technologies, Inc. (QTI) actively works with OEMs to address their thermal needs. Before the handset is ever launched, QTI provides a thermal dashboard and model to help OEMs understand how their design decisions will impact performance and temperature. Still, metals, fancy plastics and PCB layout are not the only tools to solve this problem.

\n

Snapdragon processors are designed to enable lower power and thermal envelopes by a suite of features. The Adreno™ GPU is the visual center of Snapdragon, rendering 3D environments and painting pixels to your display. There are two different methods to render 3D images to the screen, deferred and direct rendering. Adreno utilizes both methods and dynamically switches between the two modes depending on which will deliver the best power efficiency. Deferred rendering breaks the scene into smaller tiles and renders them independently. Rendering smaller tiles consumes less memory and allows operations to remain on the GPU memory, and so these operations are not penalized for accessing the larger, longer latency external memory.

\n

Direct or immediate rendering does not buffer any content, but computes the scene as a whole and renders all pixels directly and immediately to the screen. While less efficient for accessing the external memory and potential overdraw, there are still some scenes or even parts of scenes that will benefit from this approach. Because it has the flexibility to decide between the two rendering methods based on the one that delivers the optimal power efficiency, this technology is called FlexRender™.

Meanwhile Krait processors, the CPU of the Snapdragon SoC, are designed with aSMP, or asynchronous symmetrical multi-processing. Each CPU core is on an independent voltage plane. This allows each core to adjust its frequency to accomplish a task. While other SoCs force all cores to run at the same max frequency for a single-threaded task, Snapdragon allows that single active core to run at the needed speed while the others remain off or at a lower frequency.

Of course, a phone is not a phone at all without a connection to the outside world, so Snapdragon optimizes its modem for power and thermal efficiency as well. There are high level reasons behind Snapdragon processors modem power efficiency. First, QTI creates and owns all of the key IP blocks of the modem, which allows for optimization at the system level. There are also performance and power improvements from one generation to the next. Second, QTI’s history of modem leadership is evidenced by the multi-generational lead over competition, and each design is more power efficient than the last. 

\n

At the lower level, QTI has been the first to commercialize many features which enable power savings in LTE modems. 

\n

Envelope tracking is one of the more recent QTI innovations in connectivity. This technology applies to the RF (Radio Frequency) amplifier, designed to allow the voltage to adjust to achieve peak power efficiency. The excessive power output (shown in the yellow below) is dissipated as heat. Snapdragon powered devices with this feature will reduce the thermal footprint and RF power consumptions by up to 30%. Snapdragon processors will be coupled with the industry’s first modem-assisted envelope tracking for 3G and 4G LTE devices.

Connected Mode Discontinuous Reception (CDRX) can turn off the LTE receiver when data is not being actively sent or received. This simple idea can lead to significant system power savings, up to 15% lower power for web browsing and up to 20% for YouTube streaming. (See page 6 of this recent Qualcomm Technologies presentation for more info.)

\n

Not only is the Snapdragon SoC optimized for power consumption, but it also is designed to achieve the highest data rates. Starting with the Snapdragon 800 processor, QTI brought the first LTE-Advanced modem to the world. Coupled with Carrier Aggregation, Snapdragon processors can achieve speeds of up to double the previous generation. This massive speed boost can allow the phone to download your content quicker, preventing the modem from heating up over a longer period of time.

\n

QTI’s power saving features extend beyond silicon and into software. Snapdragon Battery Guru is an app designed to extend your battery life and longevity by automatically adjusting your smartphones settings. Upon installation, there is a brief learning period while the app learns your usage habits. Once it’s ready, it will disable certain features or apps when it knows you’re not using them. For example, it will learn that you are connected to a Wi-Fi signal at home from 6PM to 6AM, but during the workday, you’re only connected via 4G LTE. During the day, it will shut off your Wi-Fi connection so it is not burning unnecessary power searching for a connection. Or similarly, Snapdragon Battery Guru will recognize you do not conduct Skype calls in your sleep, so it will disable the connection to the internet if it is not needed. But if you do want to receive a Skype call at 2 a.m., Snapdragon Battery Guru allows for customization and you can override for each app as you see fit. Snapdragon Battery Guru is available on the Android Google Play store for your Snapdragon powered device.

\n"},{"type":"youtube","id":"wdgN-P0QZSg"},{"type":"html","value":"

Beyond silicon, QTI even addresses thermals at the packaging level. Snapdragon processors are now housed in 4-channel PoP (package-on-package), which lowers the thermal resistance on the package by allowing for more heat transfer back into the circuit board. This technology can help keep the SoC up to 5 to 15 degrees Celsius (41 to 59 F) cooler. Lower temperature not only results in higher performance, but up to 30% lower leakage.

\n

How does this all translate in the real world? Just take a look at the LG G2 smartphone. In a recent review by AnandTech, this flagship handset is topping the charts in CPU and GPU performance. Those high performance scores do not result in high power, as the G2 also took the top spots in their battery life tests. To quote the author, “The LG G2 battery life is shockingly good through our tests, and in subjective use.” In the talk time test, it lasted over 8 hours longer than the 2nd place contender and over 2.5x longer than the new iPhone 5s.

Not only do Snapdragon processor features allow for longer lasting battery life, but they allow for faster charging. With phones increasing in size, and battery technology improving, phones are slowly cramming more and more watt-hours or battery capacity into your device. The downside of this is that charge times also increase with battery capacity. Qualcomm® QuickCharge 2.0 improves charging by up to 75%. This more than compensates for the larger battery capacities and ensures you spend less time tethered to an outlet and more time on the go. Check out what was said about QuickCharge here.

The smartphone continues to evolve, both inside and out. These changes are opening up new worlds of usage models and capabilities that we previously wouldn’t have imagined could be housed in our pocket. With the sizeable list of engineering innovations discussed here, Snapdragon processors have paved the way for this mobile revolution. If you want the best performance and the best battery life, you want a Snapdragon processor at the heart of your device.

The engineering requirements for AS development encompassing sensors, controllers, software and communications are much the same as exist in embedded and mobile computing today. But given the uncontrolled environments in which these systems operate, there are also significant challenges in developing decision making and learning algorithms that realize the intelligence in Autonomous Systems.

\n

To succeed, developers should take into consideration how and where these systems will be deployed, and use this knowledge to select the best hardware platform for optimal performance.

\n

Insight-driven development gives leaders the edge

\n

While major corporations are already making headlines with autonomous vehicle prototypes, they’re also investing heavily in understanding the use cases, opportunities and challenges of Autonomous Systems.

\n

Amazon, for example, hasreportedly established a 12-person team to figure out how to leverage autonomous vehicles, and is hosting supply chain industry events to generate insights into the social, environmental and technical challenges faced in deploying AS in the future. It’s the kind of creative, antidisciplinary design approach we discuss in our previous QDN post on Hardware-Software Convergence. While the technology powering AS continues to be refined, its success is contingent on the quality of insight supporting its development.

\n

Hardware and software working together to realize true autonomy

\n

With opportunities to deploy these systems in the warehouse, in the air, on the road or elsewhere, the value created in AS lies in an orchestration of hardware and software. It’s critical to select a robust and versatile platform to support the varied processing demands of AS, alongside powerful development tools and libraries.

\n

Together, the Qualcomm Snapdragon mobile platform, supporting true heterogeneous computing, alongside the Snapdragon Neural Processing Engine SDK and Snapdragon Profiler, are designed to improve the performance of existing AS and machine learning applications. For example, the Google TensorFlow machine learning framework is now optimized for the Qualcomm Hexagon 682 DSP, and is engineered to allow apps to run with efficiency on mobile and embedded devices.

\n

In April, we announced a collaboration with Facebook to support the optimization of Caffe2, Facebook’s open source deep-learning framework and the Snapdragon neural processing engine (NPE) framework. One of the benefits of Snapdragon and the NPE is that a developer can target individual heterogeneous compute cores within Snapdragon for optimal performance. The NPE includes runtime software, libraries, APIs, offline model conversion tools, debugging and benchmarking tools, sample code, and documentation.

\n

True autonomy, however, will be realized through the software running on these platforms. Developers can model environments to anticipate the kind of actions their AS will perform in the field, but more critical is building the learning algorithms that allow the AS to respond appropriately to changing or challenging environments. It’s a significant computational feat requiring rapid processing of multiple sensory inputs, nimble decision making and robust operational execution.

\n

Communications underpin the entire effort. Within the system itself, of course, but also between systems, between the AS and the cloud or the AS to a human controller. They’re all integral to the performance and usability of the system. While robots deployed on premise may be able to get by on high-speed wireless mesh networks, it’s likely to be a combination of Wi-Fi, 4G and new 5G cellular networks to deliver the flexibility and redundancy that can help operate in an uncontrolled environment.

\n

Autonomous Systems: An exciting opportunity for developers ready to innovate

\n

There’s little doubt that our lives and those of our children will be significantly impacted through the development of Autonomous Systems. Whether through substitution or augmentation, our business and personal productivity looks to be greatly enhanced through artificial intelligence and Autonomous Systems are some of the most exciting manifestations of these changes. While we’re just scratching the surface of what’s possible today, AS offers huge opportunities for developers ready to take on the challenge.

\n

Stay tuned as we dive into the role of AI and the Snapdragon mobile platform in evolving Autonomous Systems, mobile/embedded computing, IoT, and XR.

Along with my colleague Alice Tornquist, I was on Capitol Hill earlier this week speaking at an event sponsored by the Congressional Spectrum Caucus, a bipartisan group established in 2014 by Congressman Brett Guthrie (R-KY) and Congresswoman Doris Matsui (D-CA) to educate their colleagues about the importance of spectrum policy and to identify ways to increase access to, and better utilize, spectrum. Congressman Guthrie and Congresswoman Matsui are leaders in this area, most recently co-authoring H.R. 1888, the Federal Spectrum Incentive Act, a bill that would provide incentives for U.S. government agencies to consolidate their use of spectrum so that more spectrum can be freed up for commercial mobile broadband. We support this legislation because freeing up more spectrum is crucial to enabling better, faster mobile broadband for consumers.

\n

Between now and 2035, around the world, 5G is estimated to generate over $12 trillion (that’s trillion with a “t”) of economic value, touching literally every facet of life. Sound spectrum policy to ensure that a steady stream of new spectrum is brought into commercial use is crucial to ensuring that 5G will be an enormous success for all of us.

\n

This brings me to the topic of the event on Capitol Hill — the steps that the U.S. government could take to facilitate deployment of 5G, and that brings me right back to spectrum. 5G will use all types of spectrum — low band, mid band, and high band. It will also use spectrum regulated under any and all regulatory paradigms — licensed, unlicensed, and shared. Moreover, spectrum to enable Gigabit LTE and 5G are inextricably linked. Gigabit LTE, using technologies developed by Qualcomm Technologies, is available today and is providing much faster and better mobile broadband with broad coverage to wide areas, while 5G commercial launches will start in 2019. Since it will take years for 5G coverage to match up with today’s LTE coverage, Gigabit LTE sets the foundation for 5G. Therefore, I’d like to share an update on recent developments in the U.S. and around the world on efforts to make more spectrum available for Gigabit LTE and 5G.

\n

Let’s start with access to low bands and the U.S. 600 MHz auction

\n

In April of this year, the FCC announced the results of its very successful auction of 600 MHz spectrum — prime, low-band spectrum that will bring greater capacity and improved coverage for mobile broadband. I say that the auction was successful because it generated more than $19.8 billion in proceeds, and it will open 70 MHz of licensed spectrum for fast mobile broadband. It was not surprising that a wide, cross section of the U.S. mobile and cable industries bid heavily in the auction for this spectrum, as the 600 MHz spectrum is especially valuable for Gigabit LTE as well as 5G. It is suited for long-range, macro deployments that are not only great for providing enhanced mobile broadband coverage over a large area, but also ultimately connecting the wide-area massive Internet of Things and more.

\n"},{"type":"image","image":"https://www.qualcomm.com/sites/ember/files/styles/optimize/public/blog/managed-images/image_1_sized_1.png?itok=efco_YJB","class":"inline","description":"Recently auctioned 600 MHz spectrum bands in the U.S.","title":"","alt":"Recently auctioned 600 MHz spectrum bands in the U.S.","width":688,"height":273},{"type":"html","value":"

In some areas, the auction winners can start using the new spectrum very quickly to expand their LTE footprint and deliver Gigabit-class LTE ubiquitously across their networks. As I explained above, providing Gigabit LTE throughout a coverage area is crucial for operators, since it will take considerable time before 5G is deployed ubiquitously, and consumers will need Gigabit LTE for high speed, high quality mobile broadband. In other areas, the process of clearing the spectrum of TV stations now using it and moving (repacking) TV stations into the remaining TV spectrum will take up to 39 months.

\n

A key part of commercializing 600 MHz for LTE is to support it in chipsets, so Qualcomm Technologies previously announced that the Qualcomm Snapdragon X20 LTE modem and RF transceiver have been designed with 600 MHz band capability, and we confirmed support for the band with the Qualcomm Snapdragon X16 LTE modem. Our advanced RF Front End (RFFE) technologies, such as dynamic antenna tuning, are designed to minimize the OEM design impact in extending their devices’ frequency range to operate in the 600 MHz band without having to increase antenna size or compromise RF performance. With broad industry support, we are working closely with operators and OEMs to enable early launches of 600 MHz-capable 4G multimode/multiband devices.

\n

5G NR will expand mobile into new spectrum bands

\n

As I mentioned, 5G will utilize all spectrum bands — from low bands such as 600 MHz, to mid bands such as spectrum around 3.5 GHz, to high bands such as 28 GHz, 39 GHz, and other millimeter wave bands — and all spectrum types from licensed, to shared, and unlicensed spectrum. In the U.S., the FCC has already allocated mid band spectrum in the 3.5 GHz range under the name Citizens Broadband Radio Service (CBRS). CBRS opens up a total of 150 MHz of spectrum for mobile use cases and introduces a new 3-tiered spectrum sharing framework that allows incumbents to efficiently share spectrum with other users, both licensed (called PAL – Priority Access Licenses) and shared (called GAA, or General Authorized Access). CBRS is expected to be launched initially with LTE and could become an important future 5G band in the U.S. Once again, Qualcomm will be leading the way in this band too with our chipsets.

\n

Last, but not least, let’s not forget the Spectrum Frontier Ruling, which I wrote about a year ago. That ruling opened up high-band spectrum in the millimeter wave range, which will play an integral role in the upcoming 5G NR deployments starting in 2019. In that ruling, the FCC issued rules for over 11 GHz of millimeter wave spectrum for 5G, but also asked for comments on a wide variety of other bands, some of which are key bands for 5G in other regions around the world. Finally, just last week, the FCC announced that it will consider a Notice of Inquiry — a request for information — on other mid-band spectrum.

\n

All in all, it is very encouraging to see the FCC continuing to work on making more spectrum available for Gigabit LTE and 5G. I know I speak for my colleagues at Qualcomm when I say that here in the U.S., we cannot wait to see the commercial launches of 5G NR — the global 5G standard — to start in 2019, and we’re all working with urgency to make that a reality.

\n

Global 5G spectrum status

\n

Identifying, harmonizing, and auctioning spectrum for future 5G networks is truly a global effort. No region can afford to be left out. Regulators around the world are tirelessly working with stakeholders across industries toward the common goal of making more spectrum available for 5G. Here is a quick summary of the status of spectrum for 5G in some places around the world:

\n\n

Conclusion

\n

At Qualcomm, we’ll be actively working with regulators, partners, and the entire industry all over the world to continue the momentum and to enable global 5G launches in 2019. Stay tuned for further updates!

Giuseppe is a mobile developer whose coding process is powered by pizza. Lucky for him, he’s based in Naples, Italy, one of the pizza capitals of the world  so he’s always powered up and ready to create a great new app. Even more so than pizza, Giuseppe is passionate about developing apps that help his users optimize their lives. He often looks to his friends and family for app idea inspiration, and that’s exactly what led him to create his popular Customer Management app.

\n

We sat down with Giuseppe to talk about his mobile development process, his favorite development tools (in particular, the Qualcomm Snapdragon Profiler), and his serious pizza habit.

\n

Can you tell us about what you do?
\n\tI’m a mobile software developer for Android and Windows Phone, and have been making Android apps since 2013.

\n

Why do you do what you do?
\n\tIt’s simple: I work to improve a user’s everyday experience. For me, innovation is about finding ways to simplify life using only a limited budget.

\n

I also enjoy creating apps in my free time to improve my skills, to be productive and stay up-to-date on the latest technologies. As soon as I have five minutes free, I use that time to develop something.

\n

How did you first get into mobile development?
\n\tI needed a weather app at the time and was not able to find one that met my expectations. So I learned how to make an app, and after three weeks I had published my very first app. I was excited because it worked well, and I was delighted by how simple and fun the process was!

\n

What’s your process for developing a new mobile application and where do you get inspiration from?
\n\tWhen I start to create a new application, I'm often very fussy. I start by meticulously asking everyone I know what they need in their lives, then I start developing immediately once I have an idea.

\n

During development, I study the similar applications of other developers, and I read their negative and positive comments for ideas. After the app's release, I read the comments of my users and always try to satisfy their requests and suggestions.

Which development tools do you use?
\n\tI had first learned about Qualcomm Developer Network tools when I was looking for an algorithm for facial recognition in real time. Facial recognition is the ability for applications to register and identify faces and the Snapdragon SDK is what I used for this  it made things easy.

\n

Today my favorite Qualcomm tools are the App Tune-up Kit and Snapdragon Profiler. I use Snapdragon Profiler during development and then I use App Tune-up Kit to evaluate app performance during testing. These tools have helped me to optimize interactive applications, reducing processing time by dividing work on each processor core to avoid blocking UI interactions. In my opinion, the Snapdragon Profiler is a must-have app that developers shouldn’t live without.

\n

When enduring a long day, what keeps you going?
\n\tPizza, pizza almost every day! My favorite food is pizza – it has a bit of everything in it, and I never get tired of eating it. As long as I’m not fixing a bug that requires a heartier source of sustenance, I always eat marinara pizza.

\n

Any other fun facts you can share with us about your work?
\n\tIn every app I’ve made there is a picture of me and my girlfriend hidden in it. If you click 12 times on the INFO button you will find it. ;)

The trusty fingerprint sensor we’ve grown accustomed to using at the bottom or on the back of our mobile devices is on the move — seen or unseen by the naked eye. At this year’s MWC Shanghai, Qualcomm Technologies announced the next generation of fingerprint solutions that will allow OEMS to incorporate the feature virtually anywhere on the device including under the display pulling off quite a feat and venturing into new territory for premium smartphones: Qualcomm Fingerprint Sensors. The suite of cutting-edge, biometric sensors for display, glass, and metal are firsts of their kind: They’re the first commercially announced ultrasonic sensors that can scan for fingerprint matches and detect heartbeat, blood flow, and gestures through OLED displays up to 1200 µm thick.

\n

A new suite of features

\n

Qualcomm Fingerprint Sensors are engineered to deliver new and enhanced features, compared with the previous generation Qualcomm Snapdragon Sense ID technology, that can transform the way users authenticate themselves on their mobile devices. The family of Qualcomm Fingerprint Sensors for display, glass, and metal give OEMs the freedom to place them virtually wherever they want on a device: under the display, metal and glass in the back, or glass under the front bezel.

\n

All three of the ultrasonic-based sensors are designed to power through common contaminants like oil and water, and can even provide consistent, reliable authentication underwater, supporting IP68 devices (water resistance of a maximum depth of 1.5 meters for up to 30 minutes). The Qualcomm Fingerprint Sensors are made also to detect the user’s heartbeat, serving as alternatives to heart rate sensors, and to detect blood flow (Liveness detection), adding another layer of mobile security.

\n

The sensors do more than verify users. Users can set directional gestures to lead to a specific UI function. For example, swiping a finger upwards over the sensor can open the device’s browser, while swiping left can pull up the user’s contact list.

Form factor freedom

\n

Thanks to the range of surfaces they support, Qualcomm Fingerprint Sensors empower OEMs to design unique form factors and designs. For glass and metal, the sensors can scan through up to 800 µm of cover glass and up to 650 µm of aluminum, improvements over the previous generation’s 400 µm capability for glass or metal.

\n

The Fingerprint Sensors are offered as both an integrated solution for current and future Qualcomm Snapdragon mobile platforms (the glass and metal sensors are engineered to be compatible with the recently announced Qualcomm Snapdragon 660 and 630 mobile platforms), and as standalone sensors that work with non-Snapdragon platforms.

\n

Commercial Qualcomm Fingerprint Sensors for glass and metal are expected to be available to OEMs this month, and are expected to arrive in commercial devices early 2018. Engineering samples for Fingerprints Sensors for Display are expected to be available for OEMs to evaluate in October this year, while commercial samples are expected to arrive in the summer of 2018.

Gigabit LTE is gaining momentum, spreading to more countries around the world.

\n

The global race was sparked by the announcement of the Qualcomm Snapdragon X16 LTE modem in February of last year. It was made real for the first time with the launch of the NETGEAR Nighthawk M1 on Telstra’s network. Then, Gigabit LTE arrived in the hands of millions of people through smartphones powered by the Snapdragon 835 mobile platform with X16 LTE, with more operator launches in the US, Europe, and Asia.

\n

Devices with Gigabit LTE capability include the Sony Xperia XZ Premium, the Samsung Galaxy S8 and S8+, the HTC U11, Motorola’s upcoming flagship smartphone powered by Snapdragon 835, and mobile broadband hotspots such as the Wi-Fi Station N-01J (for DoCoMo), Pocket WiFi 601HW (for SoftBank), and Speed Wi-Fi Next W04 (for KDDI).

\n

And now, Gigabit LTE is coming to the world’s largest mobile market China.

\n

China Mobile, the world’s largest mobile operator, and China Unicom, both recently announced field trials of Gigabit LTE technology, with devices based on the Snapdragon X16 LTE modem. This brings the total count to 26 operators in 18 countries trialing or deploying Gigabit LTE in 2017. That is up from 15 operators in 11 countries just five months ago.

\n

Naturally, the buzz around Gigabit LTE in China carried over into this year’s Mobile World Congress Shanghai.

\n

At the Qualcomm booth, we demonstrated Gigabit LTE over TDD spectrum, using the HTC U11, and showcased real-world use cases and speeds of several hundred megabits per second.

There are very good reasons why operators and smartphone OEMs around the world are embracing Gigabit LTE so boldly, and why Gigabit LTE momentum is accelerating.

\n

From a user perspective, Gigabit LTE provides many benefits:

\n\n

And from the operators’ perspective, Gigabit LTE allows them to add capacity to their networks, which improves speeds for all users, not just those with the latest devices. More specifically, Gigabit LTE allows operators to deliver video — which accounts for around 70 percent of traffic on mobile networks — much more efficiently. In fact, Gigabit LTE devices can receive video using a fraction of the resources of older LTE devices. That leaves more room for other users to stream and download as well.

\n

It is no coincidence that operators have begun offering unlimited data plans while also trialing and deploying Gigabit LTE. All four major U.S. operators now have unlimited data plans, and all four have either begun, or will shortly begin, deploying Gigabit LTE. Even in China, all three major operators now offer unlimited data plan options. Gigabit LTE will allow all these operators to expand the capacity of their networks so they can cope with the additional data traffic that will come from users with unlimited data plans.

\n

Gigabit LTE is not a fad, a gimmick, or a “check-the-box” item for the sake of marketing. It is an important milestone in the evolution of 4G networks and devices, on the path to 5G. It can yield immediate benefits today, and unlock the potential for great new mobile experiences tomorrow.

The Thermal Efficiency Behind Smartphone Trends

2013年10月9日

Qualcomm products mentioned within this post are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

In our second blog post on the power and thermal challenges that face modern devices, we will explore the current trends in the industry and the technologies and innovations that make them possible.

Our phones are getting bigger. As the capabilities of smartphones have grown, so have their screens. The increased demand for more visual real-estate on our pocketable devices is a global trend. According to ABI Research, almost 83 million phablets, or phones with a five inch screen or greater, were shipped in 2012.  That is an increase of 4,504% from 2011. The same body of ABI Research also states that shipments of such phones are expected to grow to 273 million in 2017.

Not only are these screens bigger, but they are higher resolution, which means they consume more power and require more processing horsepower. Almost every standard flagship phone today has at least a 1080p screen. Tablet resolutions are even higher, with Qualcomm Snapdragon 800 processors supporting up to 2560x2048. Armed with these larger screens and crisper resolutions, users are able to demand more from their devices. After all, watching HD video or gaming on 6” phablet is a much more immersive experience compared to the 3” pixelated phones of yesteryear.

One might expect that if mobile devices’ horsepower increased to enable these new experiences, the thickness of the device would grow as well to compensate for the added power and heat from these components. In reality, the exact opposite is true. Tablets and smartphones are getting thinner. For example, the Sony Xperia Z Ultra powered by the Snapdragon 800 processor, weighs in with a massive 6.4” display, but launched as the “world’s thinnest HD smartphone,” at only 6.5mm.

To recap: larger screens, higher resolutions, and SoCs with more horsepower, yet devices are getting thinner. How is all of this possible? The answer is great engineering.

Let’s begin with where this thermal and power efficiency is visually demonstrated. The GPU is responsible for pushing millions of pixels to your display and does so up to 60 times each second. During gameplay it is called upon to render 3D worlds in ultra-realistic detail, all while the CPU may calculate the artificial intelligence of the game characters or the physics of the explosion you just caused. All these high performance tasks could make other SoCs burn a lot of power, and generate a great deal of heat. Snapdragon SoCs have a history of being cooler than the competition.

 

Mobile devices have a very different set of thermal constraints. In the archaic PC segment, desktop computers are housed in large enclosures and are cooled by thick metal heat-sinks with a large and often loud fan. In contrast, mobile devices are mere millimeters thin and are expected to be held in your pocket, your hand, or against your cheek. There are certain thermal thresholds that must be met for a handheld to be a viable product. Skin temperature is one of them. If the devices’ thermal threshold is surpassed, the SoC begins to throttle back its frequencies, and thus performance, in an effort to reduce the heat. This can have negative impacts on performance and overall user experience. 

OEMs’ design decisions are able to help mitigate some of this heat. The proximity of high power components and the material used in the phone to dissipate the heat are some of the methods employed. Qualcomm Technologies, Inc. (QTI) actively works with OEMs to address their thermal needs. Before the handset is ever launched, QTI provides a thermal dashboard and model to help OEMs understand how their design decisions will impact performance and temperature. Still, metals, fancy plastics and PCB layout are not the only tools to solve this problem.

Snapdragon processors are designed to enable lower power and thermal envelopes by a suite of features. The Adreno™ GPU is the visual center of Snapdragon, rendering 3D environments and painting pixels to your display. There are two different methods to render 3D images to the screen, deferred and direct rendering. Adreno utilizes both methods and dynamically switches between the two modes depending on which will deliver the best power efficiency. Deferred rendering breaks the scene into smaller tiles and renders them independently. Rendering smaller tiles consumes less memory and allows operations to remain on the GPU memory, and so these operations are not penalized for accessing the larger, longer latency external memory.

Direct or immediate rendering does not buffer any content, but computes the scene as a whole and renders all pixels directly and immediately to the screen. While less efficient for accessing the external memory and potential overdraw, there are still some scenes or even parts of scenes that will benefit from this approach. Because it has the flexibility to decide between the two rendering methods based on the one that delivers the optimal power efficiency, this technology is called FlexRender™.

Meanwhile Krait processors, the CPU of the Snapdragon SoC, are designed with aSMP, or asynchronous symmetrical multi-processing. Each CPU core is on an independent voltage plane. This allows each core to adjust its frequency to accomplish a task. While other SoCs force all cores to run at the same max frequency for a single-threaded task, Snapdragon allows that single active core to run at the needed speed while the others remain off or at a lower frequency.

Of course, a phone is not a phone at all without a connection to the outside world, so Snapdragon optimizes its modem for power and thermal efficiency as well. There are high level reasons behind Snapdragon processors modem power efficiency. First, QTI creates and owns all of the key IP blocks of the modem, which allows for optimization at the system level. There are also performance and power improvements from one generation to the next. Second, QTI’s history of modem leadership is evidenced by the multi-generational lead over competition, and each design is more power efficient than the last. 

At the lower level, QTI has been the first to commercialize many features which enable power savings in LTE modems. 

Envelope tracking is one of the more recent QTI innovations in connectivity. This technology applies to the RF (Radio Frequency) amplifier, designed to allow the voltage to adjust to achieve peak power efficiency. The excessive power output (shown in the yellow below) is dissipated as heat. Snapdragon powered devices with this feature will reduce the thermal footprint and RF power consumptions by up to 30%. Snapdragon processors will be coupled with the industry’s first modem-assisted envelope tracking for 3G and 4G LTE devices.


Connected Mode Discontinuous Reception (CDRX) can turn off the LTE receiver when data is not being actively sent or received. This simple idea can lead to significant system power savings, up to 15% lower power for web browsing and up to 20% for YouTube streaming. (See page 6 of this recent Qualcomm Technologies presentation for more info.)

Not only is the Snapdragon SoC optimized for power consumption, but it also is designed to achieve the highest data rates. Starting with the Snapdragon 800 processor, QTI brought the first LTE-Advanced modem to the world. Coupled with Carrier Aggregation, Snapdragon processors can achieve speeds of up to double the previous generation. This massive speed boost can allow the phone to download your content quicker, preventing the modem from heating up over a longer period of time.

QTI’s power saving features extend beyond silicon and into software. Snapdragon Battery Guru is an app designed to extend your battery life and longevity by automatically adjusting your smartphones settings. Upon installation, there is a brief learning period while the app learns your usage habits. Once it’s ready, it will disable certain features or apps when it knows you’re not using them. For example, it will learn that you are connected to a Wi-Fi signal at home from 6PM to 6AM, but during the workday, you’re only connected via 4G LTE. During the day, it will shut off your Wi-Fi connection so it is not burning unnecessary power searching for a connection. Or similarly, Snapdragon Battery Guru will recognize you do not conduct Skype calls in your sleep, so it will disable the connection to the internet if it is not needed. But if you do want to receive a Skype call at 2 a.m., Snapdragon Battery Guru allows for customization and you can override for each app as you see fit. Snapdragon Battery Guru is available on the Android Google Play store for your Snapdragon powered device.

Beyond silicon, QTI even addresses thermals at the packaging level. Snapdragon processors are now housed in 4-channel PoP (package-on-package), which lowers the thermal resistance on the package by allowing for more heat transfer back into the circuit board. This technology can help keep the SoC up to 5 to 15 degrees Celsius (41 to 59 F) cooler. Lower temperature not only results in higher performance, but up to 30% lower leakage.

How does this all translate in the real world? Just take a look at the LG G2 smartphone. In a recent review by AnandTech, this flagship handset is topping the charts in CPU and GPU performance. Those high performance scores do not result in high power, as the G2 also took the top spots in their battery life tests. To quote the author, “The LG G2 battery life is shockingly good through our tests, and in subjective use.” In the talk time test, it lasted over 8 hours longer than the 2nd place contender and over 2.5x longer than the new iPhone 5s.


Not only do Snapdragon processor features allow for longer lasting battery life, but they allow for faster charging. With phones increasing in size, and battery technology improving, phones are slowly cramming more and more watt-hours or battery capacity into your device. The downside of this is that charge times also increase with battery capacity. Qualcomm® QuickCharge 2.0 improves charging by up to 75%. This more than compensates for the larger battery capacities and ensures you spend less time tethered to an outlet and more time on the go. Check out what was said about QuickCharge here.
