Turning the WLAN module can reduce the battery life of a powerful smartphones. If you use at home or at work, the wireless too, then that's less bad. But it is annoying when you're traveling and do not really need the wireless. Thus, the WLAN receiver scans for open wireless networks, and happily continue swallows therefore continue current.The WLAN on and off by hand is certainly a solution, but frankly annoys me something. Remedy the small program Y5 Battery Saver, the basis of the current position of the wireless switches on or off.

Therefore

Y5 Battery Saver does not just flow-eating GPS. The program determines the Cell ID is logged on which the phone mast. If you connect to a wireless network, then remembers these Y5 Battery Saver Cell ID. In the future, then the wireless is turned on when the phone is registered to this mast. Leaving the reception area of ​​the transmission tower, then the wireless is switched off again automatically.

Of course, the positioning of the Cell ID is not super accurate, but that's what did not. Most of the work, for example, is far enough away from home, so that the WLAN at the latest after a few hundred meters on the way to work, to college, is disabled … wherever. On my old Samsung Galaxy with Android 1.5, the program works pretty well and reliably.
