11 Recommendations for Optimizing Mobile Apps Power Efficiency

Following an AT&T Labs Research and corresponding paper entitled “Profiling Resource Usage for Mobile Applications: A Cross-layer Approach“,  AT&T found that a few simple design approaches could significantly improve mobile application responsiveness and reduce battery drain by lowering your application power consumption. They analyzed PANDORA internet radio and  discovered that the streaming music was delivered efficiently, but periodic audience measurements were draining battery life. Here is an excerpt of the PANDORA Case Study: While the music itself was sent simply and efficiently as a single file, the periodic audience measurements—each constituting only 2KBs or so—were being transmitted at regular 62.5-second intervals. The constant cycle of ramping up to full power (2 seconds to ramp up, 1 second to download 2KB) and back to idle (17 seconds for the two tail times, the first down from full-power mode and the second down from half-power mode) was extremely wasteful. Of the total […]

NFC Smart Meter Demo by NXP and Landis-Gyr

NXP and Landis+Gyr are showcasing smart meters equipped with NFC technology at the Metering Europe 2011 event in Amsterdam this week. The companies are demonstrating how utility companies will be able to use NFC smart meters to: Save money by removing the need to include an LCD display in a smart meter. Meter readers will instead use an NFC-enabled phone to take a reading from the meter and then use their handset to collect and view current and historical energy consumption. Use an embedded secure element in the smart meter to increase customer privacy while at the same time providing the necessary level of access to installation and service technicians. Enable authorised maintenance technicians to download metering information to handsets or tablets as well as upload firmware updates to the meter via NFC. Use secure device pairing to deliver home area network (HAN) capabilities. Provide secure and convenient pre-payment of […]
