BatteryFu battery saver

Available in :
BatteryFu (pronounced Battery-Foo, like in Kung-Fu) extends battery life (and lowers data usage) by changing always-on mobile/wifi data to periodic sync (meaning it disables your mobile data and/or Wifi, then checks your accounts every X minutes). This also provides a way to manage your data usage.

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.

See website for more information, if you have problems, or would like to donate. Email for support, I don't check comments.

Its awesome But I can't understand the settings. I only want my Wifi to turn off when screen shuts down and turns on when its active. But I couldn't put a setting to it ! help me if someone can. I've uninstalld it.

Toggle WiFi just turns WiFi off Needs instructions . Don't understand how it works.

by A Google User the 8/31/2013

perfect works perfect! it only eats a small size of data. I salute the dev.. I highly recommend this app. God speed.

by A Google User the 6/26/2013

I like it but. I like it but wish they had a battery level icon. That's all that is missing. There is no icon. What is the reason this? I am sure that adding such a feature will not increase the apps size too much. 5 stars if added.

by A Google User the 6/11/2013

Great App It does wat it says. I'm able to control my data with the widget and it auto syncs at intervals I can set. Its very useful. My only request is that u make a different widget with a better settings short cut. Its hard to hit sometimes.

by A Google User the 5/29/2013

Excellent This app really works. Simple and free of any adv gives a much needed boost to the battery life :-)

by A Google User the 4/26/2013

Good, needs refinement The settings are a little hard to understand. On the Galaxy S3 sometimes the data will not turn back on.

by A Google User the 3/28/2013

Light n fully loaded This is the smallest battery app and full of great feature. Only need battery percentage icon, so I dont have to install additional battery icon.

by A Google User the 3/28/2013
