BatteryFu battery saver
100,000 - 500,000 downloadsAdd this app to your lists
BatteryFu is also great for tablet use to keep accounts sync'd even when the tablet is in sleep/standby. Normally accounts won't sync due to WiFi going to sleep (see "WiFi sleep policy").
There are lots of other battery savers on the market, but this one has been around since 2010, and has no ads or spyware (see permissions).
* Lean and fast (see download size!)
* Work for all networks (CDMA/GSM) from Gingerbread up
* Notification icon: lets you switch modes even while inside another app.
* Data while screen is on, with screen off delay
* Data while charger is plugged in
* Pre-defined modes: Travel mode, Online mode, Offline mode, Night mode, etc.
* BatteryMinder shows battery stats, like usage during screen off, kernel wakelocks, etc.
* 3rd party app support (using intents) so that you can control BatteryFu from your own app. Email me for details.
* Do not move to SD
* Do not task kill
* Disable before un-installing
* If your battery drains more than about 10% overnight with Night mode on, then something else is draining your battery. Uninstall some apps and/or reboot.
Tips for even better battery life:
* Select "2g networks only" in Android settings
* Turn off "Network notification" under Wifi settings
* Uninstall apps if your phone is running out of RAM (e.g. slow to get to homescreen or switch apps)
* If your battery life is out of control, reset phone to factory defaults, install BatteryFu and be amazed! Then slowly re-install some apps
* Do not put apps on SD card if they run in the background. SD card access drains battery.
* Some Samsung devices drain battery overnight after Maps/Navigation is used (even with GPS off). Turning off "Use wireless networks" under Location settings and rebooting seems to help. You will see this as a long "gps" wakelock in BatteryMinder.
