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.

Meet the evolution of the touch-screen smartphone: the HTC U11. HTC’s flagship is the world’s first phone with intuitive squeeze functionalities, creating a one-of-a-kind way of interacting with the device we often have in hand. Powered by the Qualcomm Snapdragon 835 Mobile Platform, the HTC U11’s features will wow the senses with its award-winning camera; adaptive headset, speakers, and microphone; and support for multiple intelligent assistants.

\n

Gigabit speeds with the Snapdragon 835

\n

The Snapdragon 835 packs advanced features into a small size — 10 nanometers to be exact. Our premium mobile platform has an integrated Snapdragon X16 LTE modem, which is engineered to support peak download speeds of up to 1 Gbps. And while that’s impressive, it’s the real-world speeds that may truly wow you. Enjoy fast access to your files stored in the cloud, stream high quality videos uninterrupted, and download music for offline play quickly. With double the number of LTE antennas of typical LTE devices, you may get up to double the download speeds in good signal conditions, and up-to 70 percent faster speeds in weak coverage. With the Gigabit LTE capabilities of the HTC U11, you can enjoy fast speeds today, and even faster ones down the road as mobile networks are upgraded.

\n

And it’s not just download speeds – you may enjoy faster upload speeds and better coverage as well. Thanks to its support for High-Power User Equipment (HPUE) technology, the HTC U11 can enjoy up-to 30 percent wider coverage on Sprint’s LTE Plus network in the U.S.

\n

The mobile platform tackles each application with its integrated Qualcomm Kryo 280 CPU, Qualcomm Adreno 540 GPU, and Qualcomm Hexagon 682 DSP, designed to work together efficiently to manage separate workloads. These Snapdragon 835 components are also made to extend battery life: the HTC U11 delivers 3 more hours of video playback, 8 more hours of music playback, and 3.5 more hours for web browsing on an LTE network, compared to the previous generation.

\n

Engaging your sense of touch

\n

One of the things that sets the HTC U11 apart is its unique HTC Edge Sense technology, which shines the spotlight on a person’s sense of touch. It’s designed so with a simple squeeze, you can launch any app on your HTC device. You can also customize the squeeze gesture, so that Edge Sense opens the phone’s camera, an email application, or a game. It also enables Voice to Text technology: With a light squeeze, the HTC U11 will translate a spoken message into a text and send it. For more advanced capabilities, you can modify “short squeeze” and “squeeze and hold” settings to make the most of this new level of phone interaction.

\n

Audio features will have you all ears

\n

The HTC U11 is equipped with upgraded HTC BoomSound Hi-Fi Edition speakers that deliver a broad Dynamic Range of audio and high volumes. The smartphone uses four omni-directional microphones that are optimally positioned. These mics work together to record audio from all directions to produce 3D audio clips.* And when the camera is set to Acoustic Focus, the microphones are designed to work with the camera to amplify the specific sounds surrounding the subject in focus.

\n

The device comes with the latest version of HTC USonic, which incorporates Qualcomm Aqstic active noise cancellation (ANC) technology. Qualcomm Aqstic ANC technology has a dedicated hardware block on the Qualcomm Aqstic audio codec that is engineered to process all the ANC algorithms so you don’t need additional batteries and components on the headset. The advanced headset is also engineered to map the inner ear with sonar-like technology and adapt the sound profile to the ear. Combined with Qualcomm Aqstic, the headset is designed to reduce distractions around you, continuously monitor the environment’s sound levels, and quickly adjust the audio for any new disturbances.

An award-winning camera, front to back

\n

Awarded the highest independent rating ever by DxOMark, the HTC U11’s camera, powered by Snapdragon 835, deserves high praise. It’s composed of a variety of advanced technologies typically found only in top DSLR cameras.

\n

A multi-axis optical stabilization system and lightning-fast autofocus capabilities are integrated into the distinguished photo-taking machine. This works to make sure the capture is quick, photos are crisp, and videos are smooth. New white balance, noise reduction, and detail preservation enhancements help you take sharper, more balanced photos.

\n

When recording video, the HTC U11’s camera uses Auto HDR Boost, a technology that takes multiple shots, and measures the darkest shadows and brightest highlights with minimal lag. Temporal Noise Reduction can then automatically compare information in the previous and following frames to remove unnecessary noise, so the focus is on your subject and not on any miscellaneous distractions.

\n

The device’s high-resolution 16MP front camera isn’t left out either. The camera uses the same HDR Boost and noise reduction technology as the 12MP main camera. And with its UltraPixel light sensitivity setting, it can take vivid selfies, day or night.

\n

Compatible companions

\n

HTC’s latest device has the perfect partners — three of them. The HTC U11 can work with three intelligent assistants — HTC Sense Companion, Google Assistant, and Amazon Alexa — personalizing your mobile experience.

\n

HTC Sense Companion is designed to familiarize itself with your daily patterns over time, taking note of when you’re running late for an appointment or when you need to recharge your phone. Keeping the HTC U11’s performance top of mind, the HTC Sense Companion can suggest clearing junk files and unused apps to free up space and gain faster speeds.

\n

With Google Assistant, this Android-powered phone puts the world’s answers in the palm of your hand. This personal assistant can help you find facts, manage your calendar, read texts, and control your home. The HTC U11 is also the first commercially available smartphone to feature hands-free wake word access to Amazon Alexa, and has over 12,000 skills from the Alexa store at its disposal.

\n

Stunning, inside and out

\n

A smartphone with impressive insides should have striking outsides to match. Under the HTC U11’s hood, the Snapdragon 835 has an Adreno 540 GPU integrated into its platform. The GPU is made to yield lifelike visuals, and an up-to 25 percent improvement in graphics rendering and 60X more display colors, compared to previous designs. Its 5.5-inch Quad HD, 3D glass screen can display these immersive visuals under any light, even harsh sunlight. And because it's water resistant, the HTC U11 can capture photos in the rain.

\n

HTC uses Optical Spectrum Hybrid Deposition to achieve the device’s liquid glass surface, a process that involves layering its back cover with highly-refractive precious minerals. This creates a brilliant effect and highlights the phone in Sapphire Blue, Amazing Silver, and Brilliant Black (in the U.S.). The HTC U11 also boasts a new, curved look that results in 3-axis symmetry, making it slim and comfortable to hold.

\n

The HTC U11 is now available for pre-order in the U.S.

Consumers expect excellent mobile experiences everywhere they go — at home, at work, while they commute. To expand the reach of premium Wi-Fi performance to more people, Qualcomm Technologies is bringing its high-performance integrated 2x2 802.11ac Wi-Fi with MU-MIMO to the Qualcomm Snapdragon 660 Mobile Platform. Until now this was only available in the Snapdragon 800 mobile platforms tier.

\n

Devices that support 2x2 Wi-Fi have two antennas instead of one. With double the antennas, Snapdragon 660 and 800-series mobile platforms with this technology are engineered to provide up to twice the user throughput and a significant improvement in coverage, which is especially useful in homes and offices with brick and concrete walls. This 2x2 Wi-Fi technology also supports MU-MIMO and is engineered to boost the performance of crowded networks by allowing multiple devices to be served simultaneously.

\n

\n

\n

Qualcomm Technologies worked with a leading Chinese OEM to test 2x2 Wi-Fi in a real-life scenario. For this reason, we set up a Wi-Fi network in a typical 100-square meter apartment in a busy, multi-story residential building in Shanghai, China. We found that devices with 2x2 Wi-Fi delivered double the throughput, eliminating dead spots in hard-to-reach areas of the apartment.

\n

In addition to 2x2 Wi-Fi, the Snapdragon 660 is designed to support a slew of advanced Wi-Fi features, including LTE/Wi-Fi antenna-sharing technology, which offers OEMs the option to offer 2x2 performance using only one antenna. As the name suggests, this features allows both LTE and Wi-Fi systems to intelligently share a single antenna. This can help them to create thinner phones or pack in more features with the space saved.

\n

The Snapdragon 660 mobile platform boasts Dual Band Simultaneous technology (DBS), which allows phones to use both 2.4-GHz and 5-GHz Wi-Fi bands simultaneously. This can lead to better performance and new use cases like using a smartphone as a Wi-Fi hub, and streaming internet content from your smartphone to a television and Wi-Fi enabled speakers. The 660 supports Bluetooth 5 as well, which can double the amount of data that devices can transfer compared to the previous generation.

\n

The Qualcomm Snapdragon 660 mobile platform is available now. Get full specs and download the product brief.

Qualcomm has been connecting people for the last 30 years, and over the next 30 years, we will be connecting them to the world of things around them. A key part of this vision is 5G, which will allow us to take the largest technology platform in human history — mobile — and extend it to virtually every industry, every object and every connection through intelligent connected platforms. But we do not have to wait for 5G to start the expansion into industrial IoT using private networks. We can start with private LTE networks now. In fact, trials are already planned for this year.

\n

The concept of private LTE networks is not new, but with the recent confluence of new spectrum sharing innovations and the genesis of “Industry 4.0” — the digital transformation of industrial processes and the fourth industrial revolution — the potential for private LTE networks is substantial. A recent study from Harbor Research indicated that the private LTE network market could reach $17B (USD) by 2022. Already today, we see strong interest from a range of industry segments, from manufacturing automation and shipping ports to oil & gas and power generation plants (see Figure 1).

Setting private LTE networks apart from public networks

\n

The unique concept of private LTE networks is that they empower enterprise customers to run their own local network with dedicated equipment and settings. This approach provides three key benefits:

\n
    \n
  1. Locally controlled: By using dedicated equipment, the private LTE network and its performance is independent from other users, and free from issues such as sudden traffic surges that can happen in a shared network. This benefit is essential for industrial and enterprise applications where productivity must be maintained at high and predictable levels. Having a local and dedicated network also enables full control of the data. For example, a company can ensure that sensitive data does not leave the premises.
  2. \n
  3. Optimized: By serving the needs of a single company, the private LTE network can be tailored for that company’s specific IoT applications. Examples of such optimization are quality-of-service (QoS) and mobility settings. With customized QoS, consistent service can be provided for the critical applications irrespective of the network load. With customized mobility settings, the behavior can be optimized for local applications; for example, to perform a faster reconnection in the unlikely event of a link failure.
  4. \n
  5. Readily deployed: With shared and unlicensed spectrum available for anyone to use for private LTE networks, deployment of private LTE networks is easy, which enables new entities to enjoy LTE. This will expand the overall LTE ecosystem. In addition, the ability to leverage the LTE roadmap allows access to features such as self-organizing networks and to network architectures with both self-contained or virtual/hosted core networks.
  6. \n
\n

The benefits of using private LTE networks

\n

Now that we know what a private LTE network is, let's look at the benefits of using LTE-based technologies. As the figure below illustrates, the key benefits compared to other wireless local networks are: higher capacity supporting many devices at the same time as high bandwidth applications, longer range, seamless mobility, industry-grade reliability, consistent latency with quality of service, security, and last but not least, its interoperability between multiple suppliers and a roadmap to 5G. The roadmap to 5G ensures a future-proof solution with new 5G capabilities such as the new 5G new radio (NR) and mission-critical services with ultra-reliable and ultra-low latency communications.

So, what's new you may ask? Mobile network operators can offer private LTE networks by dedicating a portion of their license spectrum, which is, and will continue to be, an important part of the private LTE market. What is new is the progress around spectrum sharing, in other words unlicensed and shared spectrum. In a recent blog post, we outlined the progress from the first concept of LTE in unlicensed more than five years ago, to the MulteFire Alliance releasing its MulteFire 1.0 specification earlier this year, to 3GPP recently starting a study on 5G in unlicensed spectrum.

\n

These efforts have mainly been focused on unlicensed spectrum, but lately there is also excitement around shared spectrum. In the U.S., the FCC has defined the Citizen Broadband Radio Service (CBRS), which is a 150 MHz shared spectrum band around 3.5 GHz. To support deployment of LTE-based technologies in this band, we co-founded the CBRS Alliance. With MulteFire and CBRS, we now have two new solutions that can be used for private LTE networks MulteFire in the globally available 5 GHz band and LTE-TDD in the U.S.-based CBRS band. A key novelty with these solutions is that they do not require licensed spectrum, which significantly reduces the bar for new deployments and opens private LTE network deployments to a wider ecosystem.

\n

The latest news about trials and demonstrations

\n

Progress has been happening on many fronts. At Mobile World Congress (MWC) 2017, we demonstrated a private LTE-based network for Industrial IoT based in an industry collaboration between Qualcomm Technologies, Nokia and GE Digital. This collaboration will continue with further research and live field trials throughout 2017.

The Thermal Efficiency Behind Smartphone Trends

9. Okt. 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.
