Comments on BatteryFu battery saver for Android

★★★★★ Galaxy S Maybe bug? When Standart mode (with "Wait till screen unlocked") selected after Offline mode, Data don't restored (if enabled). Display at this time is turned on. Good way - save state before change mode, and restore it if needed. It would be nice if you add "marker" in menu from status bar for active mode (Standart, Online, Offline, Night). For example: * Standart mode (Data managed by app, if selected) Online mode. Offline mode. Nignt mode (Data managed by app, if selected) If user manually switch Data off, marker must be "Offline mode". Standart mode Online mode *Offline mode (always offline) Night mode If user manually switch Data on, marker must be "Online mode". Standart mode *Online mode (always online) Offline mode Night mode After select "Standart mode" or "Night mode" data managed by app. Sorry for my English :)
★★★★★ Top App works perfectly on Samsung YP-G70 I have been looking for something like this for ages but missed it because I was searching under WiFi for a toggling device. This app is totally user configurable and you can choose whether or not to toggle mobile data, which I would not want to do unless I had an unlimited data plan. You can choose to have an icon on the notification bar and detailed status information is also given in the notification area, which is useful. The app is only a few kilobytes and uses virtually no power itself. If you use BatteryFU's own menu (main screen) to control your WiFi, you will not create any conflicts with scheduled events. A 2-star reviewer has not realised this! My only criticism (and it really is nitpicking) is that the menu categories could be better named, for example: "Toggle Data", "Always On", "Always Off", "Night Mode", would be clearer than the ones used. I had to experiment a bit to determine exactly what the actual options meant. Still a 5 star rating, it works perfectly and is completely reliable. Also works on my wife's Sony Xperia. BatteryFU works better than some similar paid-for apps, is free and I have not seen any adverts so a big thank you to the developer. EXCELLENT.
★★★★★ Super data and battery saver Superb app. Saves battery and periodically turns on/off data. Has option to turn off data when phone is on every time. Works great.
★★☆☆☆ No battery minder section Why i m not provided with battery minder section i only installed for that only
★★☆☆☆ Samsung Galaxy S GT-I9000 with CM11 Installed it from F-droid. Works erratically & is not able to switch mobile data on/off properly. Even after exiting the app & restarting mobile without starting the app it didn't let mobile data connect until I uninstalled the app. Gets an additional star for GPL.
★★☆☆☆ Needs work. Does not re-enable data after night mode. SGS3.
★★☆☆☆ Unpredictable I like what this app is supposed to be doing, but it seems to be inconsistent about doing it. It turns off the wireless while I'm actively using it, but then seems to turn it on while the device is off. To date, I haven't really seen much of an improvement in battery life either, so I'll uninstalling it shortly.

Description by Toby Kurien Written by the developer, not by AppBrain. Click to read.
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").

*NOTE*: BatteryFu requires root on Android 5+ to toggle mobile data.

BatteryFu is open source software.

Features:
* 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.
* Open source

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.
