One of the major pitfall of Android operating system is that even emerging newer and better versions of its firmwares , the short battery life problem still remains continue. It is not that your phone doesn't provide you a good battery backup but the main reason behind battery drain is that battery resources are used by applications installed in your phone which keeps on using power unnecessarily. Sometimes you might have seen that even after you exit from some application and lock your phone but when you take it out of your pocket it's display light is still on. This is because application that makes your phone WakeLock.
Thanks to Android application developers who developed Wakelock Detector to solve battery issues. Wakelock Detector apps helps you to detect the apps that have been using your phone's battery unnecessarily by checking the wakelock history at regular intervals. This makes you understand that which applications kept using your phone's battery when it was idle.
Wakelock Detector shows all the statistics about the applications , their battery usage , CPU awake time and much more even since your device was booted up. By default it sorts the application which has caused most awake time , if you want to see which app is keeping your screen on after screen timeout you can see it under Screen Wakelock and if you want to see currently running application then you may change sorting type to running.
How to Use WakeLock Detector?
- Put your phone and charging and charge it until the battery is more than 90% or simply restart your phone.
- Now unplug the charger and use your phone normally as you do for 2-3 hours.
