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.

Extended Reality (XR) encapsulates Augmented Reality (AR), Virtual Reality (VR), mixed reality (MR), and everything in between. Previously in XR, users have only been able to look in the X/Y/Z axes yielding three degrees of freedom (3DoF). This was great for stationary 360-degree video experiences, but underwhelming when it came to total immersion. Unlocking movement on the X/Y/Z axes, in addition to looking in the X/Y/Z axes, gives developers a total of six degrees of freedom (6Dof) and a much more immersive user experience.

Now that users can operate in 6DoF they want to move around more, but the current tethered VR solutions can hinder that ability. The Qualcomm Snapdragon 835 VR Development Kit is designed to support 6DoF in a standalone mobile solution. It does this by harnessing the power of the Qualcomm Adreno 540 GPU and the Qualcomm Hexagon DSP. The Adreno 540 GPU offers Open GL ES 3.2 and DirectX 12 support in a 10nm package, and the Hexagon DSP is dedicated to offloading the 6DoF calculations from the GPU while sampling at 800Hz. All of this power packed into a head mounted device (HMD) unlocks the potential for truly immersive experiences.

To create 6DoF the Snapdragon VR Dev Kit combines two monochromatic (1280 x 800) global shutter cameras and an inertial measurement unit with fast interface Snapdragon 835 integrated sensor core. It then uses the DSP Sensor Fusion that is built into the SDK to combine camera images along with high frequency positional data as well as high frequency inertial data from gyroscopes and accelerometers to provide the final tracking data.

Qualcomm Technologies (QTI) joins ONNX

\n

In September, Facebook and Microsoft introduced the Open Neural Network Exchange (ONNX) format. ONNX is an interchange format intended to make it possible to transfer deep learning models between the frameworks used to create them.

\n

With ONNX, Facebook can acquire a trained model created elsewhere with PyTorch, for example, and use it with Caffe2 Facebook’s preferred framework - for the inference stage of machine learning. Microsoft, in turn, has announced that its own Cognitive Toolkit will support ONNX, initially for inference.

\n

This initiative aligns with our goal of supporting neural network execution on Qualcomm Snapdragon mobile platforms that can be accelerated by the Snapdragon Neural Processing Engine (NPE) SDK. As such, QTI welcomes the opportunity to participate in ONNX, which helps make it easier for developers to utilize multiple frameworks.

\n

What ONNX means for OEMs, ODMs and developers

\n

Openness generally works in favor of the developer, so there are several ways that your AI applications can benefit from ONNX:

\n\n

ONNX holds the promise of smoothing the path between research and production.

\n

Next steps

\n

Curious? You’ll find ONNX source code, documentation, binaries, Docker images and tutorials available right now on GitHub. Test-drive ONNX. We’ll keep you posted on progress of ONNX integration into the Snapdragon portfolio.

Every once in a long while, a new technology comes along that redefines the boundaries and assumptions that came before it. While it is still being extensively tested, 5G NR mmWave is emerging as a key technology that could define the next big moment in the mobile industry, ushering in the next generation of user experiences and significantly increasing network capacity.

\n

It is coming at just the right time, too. Mobile networks are facing soaring demands for mobile data as consumers increasingly utilize mobile devices to share and consume high-fidelity multi-media. On top of this, as the capabilities of mobile devices continue to grow — think high-resolution cameras, 4K video, VR, AR— so does the ever-increasing consumer demand for faster, better connectivity.

This insatiable demand for mobile broadband was recently validated by a global 5G Consumer Survey that Qualcomm conducted. The survey found that approximately 50% of consumers surveyed were likely to purchase a smartphone with 5G when it’s available. The consumers cited 10x faster speeds, 10x quicker response time, and more cost-effective and unlimited data plans as the top reasons.

\n

To fuel this ever-increasing demand, we need access to more spectrum. Spectrum is the lifeblood of mobile connectivity. It is simple — more spectrum means more network capacity, which means faster data rates and better user experience. One key opportunity 5G will bring is making use of new higher spectrum bands not previous suitable for mobile communications. 5G NR — the global 5G standard — is being designed not only for bands below 3 GHz where most mobile communications happen today, but also to provide a unified design that will make use of mid-bands, such as 3.3 to 6 GHz, as well as high-bands above 24 GHz, loosely known as mmWave.

Although the use of bands above 24 GHz for wireless communications is nothing new, mmWave is a completely new frontier for mobile that is very compelling as the large bandwidths available at these high frequencies enables extremely high data rates and significant increases in capacity. mmWave bands have been utilized for quite some time in fixed, line-of-sight wireless communications for fixed wireless backhaul and satellite communications. However, increased propagation loss, susceptibility to blockage (e.g. hand, head, body, foliage, building penetration), and RFIC complexity and power-efficiency, has historically made these high-bands not feasible for mobile communications. That is, until now. 5G NR based mmWave is changing this, and Qualcomm is leading the way.

\n

There is a decent amount of skepticism in the industry on the ability to make mobile 5G NR mmWave a commercial reality in 2019 — overcoming the challenges at these higher frequencies to deliver robust mobile communications in mobile form factors, like smartphones.

\n

At Qualcomm, we have a long history of solving wireless challenges that others thought were impossible. We have been working on the key design elements necessary to harness mmWave bands for usage in mobile broadband communication systems — proving to both ourselves and the industry what is feasible and what needs more work. I am very excited to share with you some of the progress we’ve made on this subject.

Demonstrating sustained mobile broadband communications in real-world environments

\n

At Mobile World Congress in Barcelona earlier this year, we demonstrated our first-generation 5G mmWave prototype system, operating at 28 GHz. The prototype system and over-the-air testing was conducted utilizing our 5G mmWave trial network we built at our Research Center in New Jersey. Our testing went far-beyond the typical 5G mmWave industry demonstration of a multi-gigabit, line-of-sight mmWave communication link. The testing showcases how advanced 5G NR adaptive beamforming and beam tracking techniques can be utilized to deliver robust mobile broadband communications in real-world environments. These real-world environments included device mobility inside a moving vehicle, indoor mobility in an office environment including wall penetration, dynamic body- and hand-blocking, and fast beam-switching between multiple base stations (gNodeBs). Check out the video below to learn more about our prototype system and extensive over-the-air testing.

Showcasing significant outdoor mmWave coverage is possible utilizing existing LTE sites

\n

Another common area of skepticism for utilizing mmWave bands in mobile networks is the need for massive small cell deployments to take advantage of these technologies. This need for many new small cell sites leads some to believe that even if 5G NR mmWave could deliver robust mobile communications, it will take many years to reach commercial reality as deploying all these new sites would take a lot of time and investment by mobile operators.

\n

5G NR mmWave will require dense network topologies with inter-site distances of ~150 to 200m. However, based on a set of simulation studies we recently performed in large cities across the world (results for five global cities shown below in Figure 2), we have shown that significant outdoor coverage is possible utilizing existing LTE macro and small cell sites. This significant outdoor coverage makes mobile deployments based on existing cell sites possible, especially when considering the tight-interworking of 5G NR with LTE to fill in the coverage gaps.

We recently demonstrated our San Francisco simulation at Mobile World Congress Americas (see Figure 3 below). Beyond showcasing decent (~65%) downlink coverage in an ~10 km2 area of the city, the coverage simulation also showcased even better coverage (>80%) in a 1 km2 downtown section by co-siting with existing LTE dense deployments. The simulation also showcased that even at the cell edges, 100+ Mbps peak data rates were possible due to the large channel bandwidths possible at these high-frequency bands. Although mmWave outdoor-to-indoor coverage for mobile is not feasible, this decent outdoor mmWave coverage frees up sub-6 GHz (either LTE or 5G NR) for outdoor-to-indoor capacity. In addition, outdoor mmWave coverage can be complemented with targeted indoor mmWave deployments. We plan to publish a whitepaper later this month that details these network coverage simulations, including new simulations for indoor environments. In the meantime, more information is available by downloading our 5G NR mmWave presentation.

Demonstrating an optimized RF Front-end design in smartphone form factor

\n

The dominant mobile form factor today is, of course, the smartphone. Over the last 5+ years, RF complexity in our mobile devices has exploded due to the increasing amount of frequency bands and band combinations. Adding mmWave to 5G mobile devices will even further increase this complexity as it will require mmWave RF Front-end (RFFE) modules with multiple antenna elements for beamforming in X-, Y-, and Z-directions. Furthermore, multiple locations will be required to account for body- and hand-blocking. And therefore, another source of skepticism with utilization of mmWave bands for mobile is whether fitting this RF complexity into a smartphone form factor is even possible.

\n

We recently announced our new 5G NR mmWave prototype and trial platform to accelerate mobile deployments for smartphones. The 2nd generation 5G mmWave prototype is based on the 5G New Radio (NR) Release-15 specifications being developed by 3GPP and will be utilized in upcoming 3GPP-based 5G NR mmWave interoperability testing and over-the-air 5G NR trials starting in the second half of 2017. With support for 800 MHz bandwidth and advanced 5G NR technologies including advanced channel coding, the prototype system is designed to support peak download speeds of up to 5 gigabits per second.

\n

The UE prototype enables over-the-air testing of real-world mmWave mobile challenges, such as device and hand-blocking. Additionally, it provides mobile device OEMs an opportunity to gain an early start at optimizing their devices for the unique challenges associated with integrating 5G NR mmWave technologies in form factor-accurate devices.

\n

Making 5G NR mmWave a 2019 commercial reality… in your smartphone

\n

There is still work to be done in order to make 5G NR mmWave a commercial reality in 2019.

\n

First and most immediate, the anchor of the 5G NR mobile experience will be Gigabit LTE. Gigabit LTE is providing the first glimpse of 5G enhanced mobile broadband today and is an essential upgrade for mobile networks on the path to 5G. Qualcomm has been leading the way on Gigabit LTE, which has truly become a global phenomenon in 2017.

\n

On the 5G NR front, the industry is hard at work finalizing the first release (Rel-15) of the 3GPP technical specifications, including the Non-Standalone (aka NSA) 5G NR specifications that are expected to be completed at the end of this year. Our Qualcomm Research 5G NR prototype systems, both mmWave and sub-6 GHz, were designed to track and drive this standardization process. As such, these prototype systems are built to support early 3GPP-compliant 5G NR interoperability testing with infrastructure vendors starting later this year. This will then lead to 3GPP-compliant over-the-air trials with mobile network operators that will test 5G NR mmWave and sub-6 GHz technologies in real-world deployment scenarios and use cases.

\n

The testing and trials intend to drive the mobile ecosystem toward rapid validation and commercialization of 5G NR technologies at scale. Qualcomm Technologies is utilizing learning from the testing and trials to help continue to drive the ongoing development of the Qualcomm Snapdragon X50 5G modem family, with the first 3GPP standard-compliant 5G commercial products, including premium smartphones, featuring Snapdragon X50 5G NR modems expected to be available in 2019.

\n

Although there is still work to do, we are confident that we can achieve this next big moment in the mobile industry, making 5G NR mmWave a commercial reality in 2019 mobile networks and mobile devices, including smartphones. But don’t just take my word — learn more by downloading our new presentation and watching our recent webinar.

Are you developing in the cloud? Well, your processes may soon be changing. By the end of the decade, edge computing is projected to become the dominant computing model. Peter Levine of Andreessen Horowitz has boldly predicted that cloud computing as we know it is coming to an end because developers and companies see the benefit of moving from centralized computing processes to decentralized ones.

\n

Luckily, developers working with the DragonBoard 410c from Arrow Electronics and other embedded hardware already possess many of the tools needed to make this shift. With the addition of cutting-edge frameworks like AWS Greengrass, developers can start experimenting with edge-computing applications today. Let’s dive into this new process.

\n

What is the edge?

\n

The edge computing model is an updated way of managing cloud computing systems where the data processing is done at the “edge” of the network, closer to the source of the data. By using local processors and storage as the primary computational device for an application, the time spent relaying all information back and forth from a central, remote data center is reduced.

\n"},{"type":"image","image":"https://www.qualcomm.com/sites/ember/files/styles/optimize/public/blog/managed-images/0f6a2472_pipe-inspector-high-res-photoshopped_0.jpg?itok=zVRZt07S","class":"inline","description":"","title":"","alt":"","width":8688,"height":5792},{"type":"html","value":"

As computing gets more complicated and handles more data, using local computing power can help lower latency. For example, in artificial intelligence (AI)-powered programs, algorithms make hundreds of decisions a second. In industrial manufacturing, multiple processors take input and coordinate responses simultaneously. In augmented reality (AR) systems, a program synthesizes HD graphics and geospatial data in real-time. The latency in a cloud-based computation model is inefficient for these types of applications, which will become even more apparent with the increase in processing power for local devices.

\n

That said, cloud computing is not obsolete. The cloud informs the edge, empowering it with important data and instructions. Whether informing local devices through deep learning models it has previously trained, or supplying application-specific contextual data (such as feature maps for autonomous vehicles), the cloud still serves many critical functions.

\n

Edge your bets

\n

Of course, these predictions could be completely off, but we’re willing to bet the edge is where computing is headed. At Qualcomm Technologies, we’ve been talking about the importance of the edge for years. We’ve seen how the requirements of recent technology trends are driving the modality shift to edge computing, and especially in these key areas:

\n\n

We’re not the only ones who feel this way: venture capital agrees. Peter Levine from Andreessen-Horowitz has provocatively suggested that the age of edge compute is taking over the cloud.

\n

“The current model of cloud computing [is] too slow. A small difference in the time it takes to refresh a machine learning model for a drone or car could be the difference between life and death. Computation will move to the edge. The same drones, cars, and IoT devices that need their models updated quickly will form a peer-to-peer network with which to distribute time-sensitive tasks...cloud servers [will] still be around...responsible for doing offline computation across large data sets.”

\n

Get an edge on the competition

\n

Since edge computing is still in its early stages, now is a great time to get started as a developer. One tool that can help you get rolling is the DragonBoard 410c. Thanks to a few key features, this development board is a good entryway to utilize the established ecosystem of sensors and tools. However, developers working with heavier edge computing loads may want to consider using the Qualcomm Snapdragon mobile platform, since this opens up access to a wider range of tools such as the Qualcomm Snapdragon Neural Processing Engine.

\n

To get started with edge computing, we recommend AWS Greengrass, which is an especially powerful framework because:

Ready to dive into edge computing? We have a project on QDN for AWS Greengrass on DragonBoard 410c with set up instructions to get you started today. We hope you enjoy developing on the cutting edge. (Sorry, couldn’t resist!)

The Thermal Efficiency Behind Smartphone Trends

Oct 9, 2013

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.
