The battery life of cell phones just doesn’t seem to be as long as it used to be. If your Android device is dying faster than you would like, Wakelock Detector can help you to home in on apps you have installed that might be killing your battery or preventing the screen from switching off.
We have looked at some of the ways in which you can track down the source of battery problems and Wakelock Detector is a free app that can be used to track down those apps and services that are causing your battery to deplete. Android itself can provide some information about how your battery is being used, but it does not reveal anything close to the full picture.
It’s important to remember that wakelocks in themselves are not necessarily a bad thing. They occur to prevent apps from being cleared out of memory so that it can keep running in the background – so email can be checked when your screen is turned off etc – but not all apps are well behaved.
