Android manufacturers - and users, for that matter - are in a constant hunt for techniques to improve battery life. In its recent Android 4.0 update for the Xperia P, Sony Mobile included a feature that it says will help achieve that goal.
Sony has posted details on Extended Standby Mode, a new ICS feature that it claims can supply up to four times as much standby time. The feature works by intelligently killing off background processes and apps that are known to use battery even when the screen isn't actually on. When Extended Standby Mode is activated, the phone allows processes to run for 15 minutes. Then, ESM closes apps, suspends notifications, and illuminates the LED light only to warn of a low battery. Calls, SMS, MMS, Alarms, Calendar notifications, and ongoing streaming activities (music or podcasts), continue without issue. Other background apps are shut off.
Extended Standby immediately shuts off once the user reactivates the phone. This isn't a good option to enable if someone wants to preserve full multitasking or get notifications from apps like Facebook, but it's a way to quickly disable and restart useful features that drain the battery. Sony says this method limits the adverse effect of apps pulling down data when you don't need to access the phone. Extended Standby Mode is so far used only on the Xperia P with Android 4.0, but it's likely to appear in other devices.source: Sony
