What Drains The Battery In Smartphones?
By Charles Limonard,
Product Marketing Manager,
Dialog Semiconductor E ven in the fast-paced technology sector, few products advance as quickly as the smartphone. In the past, functions such as navigation, enabled through the Global Positioning System (GPS), could easily be pinpointed as major consumers of power. Similarly, WiFi represented a major battery drain, particularly if the RF conditions were poor or the home router or base station was working at the edge of its range. While moving around, frequent handovers between cellular base stations would increase traffic to and from the handset, again leading to a significant power demand. As handover would often happen on the edges of cells, those signals would also need to be boosted, which means more power being supplied to the RF power amplifiers. Because 2G signals are more efficient under these conditions at low data rates, a common piece of advice was to force the device to avoid using 3G or 4G communications. Until recently with Bluetooth
Smart, there had not been any major changes to the core protocols that influence power consumption. The increasing use of apps that communicate in the background have made the traditional advice of turning radio subsystems off impractical. Instead, smartphone and tablet manufacturers have made the firmware that controls these subsystems much smarter. The firmware analyses conditions in real time and continually adjusts how the device responds.
The firmware will prevent unnecessary cellular handovers and only activate the GPS decoding engine when the software decides it needs a new position reading, based on changes since the most recent fixes. A phone that has been stationary for a while does not need to update nearly as often as one on a dashboard in a moving car. The conditions that lead to higher than expected battery drain are now increasingly more subtle, making them harder to identify. Apps now provide the key influence over long-term energy consumption. Some ask for information from the firmware more often than is required and do not give the firmware the opportunity to optimise battery drain. This means that one app that asks for permission to see your location in real time, even when running in the background, may have little impact on power while another similar app is far more power demanding. This is one reason why there is an emergence of apps that sample system state at regular intervals to find likely power hogs.
Still, not everything has changed. The display remains one major power consumer on smartphone platforms. To make the screen readable under the brightest of ambient lighting conditions, the LEDs in the backlight, which form the actual pixels in the case of OLED displays, are designed to be able to operate at high intensity. This can rapidly drain the battery if the screen is set to not power down after inactivity.
Tests have shown that doubling the brightness of a backlight increases the power consumption approximately four-fold. At maximum brightness, the backlight can easily consume twice as much as the average power demand of the applications processor and its memory subsystem while it is running. However, even here greater attention to power efficiency has taken hold, with ambient light sensors used to tune the backlights output to a level appropriate to the conditions, while the efficiency of the white LEDs has increased significantly leading to lower power at the same intensity. Bluetooth is an example of how the emphasis on power efficiency has shifted to ambient intelligence around the mobile device. Bluetooth Smart increases the already impressive energy efficiency of the protocol to the point where a sensor device can run for over a year on a lithium button cell. As a result, Bluetooth Smart is key to the design of a growing list of wearables, including step counters and heart-rate monitors. These devices feed a stream of information to smartphones and can do so without significantly draining the battery of either device. This is a testament to the way that mobile-device design has reacted to power-consumption issues. The most successful of these devices employ a divide- and-conquer strategy to ensure the most appropriate and energy-efficient method for dealing with data is used at any one time. At other times, a processor that is less power hungry runs many functions, letting the larger core power down.
The sensor hubs in many of the latest smartphones take this philosophy even further. These devices are based on simpler implementations of the ARM architecture, such as the Cortex-M0+, rather than the Cortex-A53. The M0+ device intercepts many of the messages from sensors, storing their data ready for the applications DESIGN TALK
The display remains a major consumer of power, but there are many others in todays smartphones . (Image courtesy of Dialog Semiconductor.)

If a message shows a sudden change, it can interrupt one of the higher-performance cores that are able to turn the appropriate software. Very often the phone can make huge improvements in battery life by intercepting these packets of data. Emerging applications such as voice activation also make use of these techniques. The first and lowest-power layer of processing looks for noises, the second, whether its a voice and finally whether or not it sounds like a command. The voice-recognition software is only deployed when it is absolutely needed. This division of responsibilities means the phone is always ready to obey voice commands but it has negligible impact on power. The complex mixture of processors and memory within the phone has driven a corresponding revolution in power management. The power management integrated circuits (PMICs) that control how electricity is delivered to each part of the phone, from the microphone to the processor array to the displays, now have tens of voltages lines with each one individually controlled in real time. Their I/O pins are as numerous as those found on the SoCs they power. The PMIC has to carefully orchestrate power to each electronic device in the smartphone. Not only are they switched on and off at different times, the voltages they receive need to be carefully tuned. The LPDDR3 memory that holds data for an applications processor may only differ by 0.1V from that used by the processor core and may need to be powered up before the core is activated. The order is often critical to avoid damage, so they need different, precisely controlled voltage rails. The efficiency targets for the PMICs have also shifted. Traditionally, power supplies have been optimised for efficiency at high load. This helps ensure mobile devices do not heat up excessively when performing intensive operations. But in an always-on environment where data is continually being processed in the background, broad- spectrum efficiency is now the requirement. The PMIC uses sophisticated digital techniques to deliver efficiencies of more than 90 per cent from low to high loads across the many voltage rails. The spread from low to high load can be orders of magnitude; from a few milliamps in a device that is idling to sudden peaks of well over 10A as a processor starts up and begins to work through data as quickly as possible. This happens before dropping to a few hundred milliamps for sustained video decoding or a series of Facebook updates. As a result, the power subsystem has become the key for ensuring that a smartphone can survive for more than one day on a single charge without demanding that users disable the functions for which they bought the device.

UAMPS encourages its members to participate in efficiency and conservation programs, and will strengthen and promote current and new programs. Widespread media coverage of climate change and pollution has resulted in consumers being more willing to embrace conservation. New appliances and electronic devices [LED light bulbs] are becoming more energy-efficient, as are homes and offices. Smart meters and thermostats [hacker alert!] and other new technologies allow consumers to be more in control of their energy consumption. Conservation and efficiency hold great promise to reduce the demand for energy.

Most Efficient Commercial Solar Panels In USA To Come From SolarCity?
On October 2, SolarCity announced that it has developed the worlds most efficient solar panels. The new panels convert more than 22% of sunlight into electricity. SolarCity will begin producing the first of the new panels in small quantities this month at its 100 MW pilot facility. Later, production will shift to the companys new 1 GW facility in Buffalo, New York. It expects to build up to 10,000 solar panels every day at that facility when it reaches full capacity.
Results suggest that the industry was a net consumer of electricity as recently as 2010. However, there is a >50% that in 2012 the PV industry is a net electricity provider and will pay back the electrical energy required for its early growth before 2020. Further reducing energetic costs of PV deployment will enable more rapid growth of the PV industry. There is also great potential to increase the capacity factor of PV deployment. These conclusions have a number of implications for R&D and deployment, including the following: monitoring of the energy embodied within PV systems; designing more efficient and durable systems; and deploying PV systems in locations that will achieve high capacity factors.
SolarCity (NASDAQ:SCTY) announced that it has been able to produce ~22% efficient modules at its 100 GW Fremont pilot plant.
