Ever wondered why your smartphone screen doesnt turn off automatically when it should have, the screen wakes up all of a sudden or you find your phone battery drained even when you exited apps and turned off the screen? This might be due to wakelock holding apps. ”Wakelock Detector” helps you to detect battery draining apps in your Android phone by checking wakelock usage history. Now you can easily find out what keep your phone awake and drain your battery when it is idle!
“Wakelock” is a mechanism of power management service in Android OS, which can be used to keep CPU awake (Partial wakelock) and keep the screen on(Full wakelock). Applications which use wakelock privilege improperly leads to situations where the CPU or phone screen stays active without user's knowledge and thus causing dramatic battery drain.
“Wakelock Detector” shows wakelock usage statistics for all applications, which ever held wakelock since boot. By default it displays CPU wakelocks sorting by the longest usage time. Further, you can choose Screen wakelock type to see screen related wakelocks. For instance, if your screen is keeping on even after screen timeout or your screen turns on randomly by itself, then you can choose Screen wakelock type on the top (Brightness icon) to see which apps are using screen wakelock. Furthermore, if you are interested in currently running applications then you can change sorting type to "Active" which shows active running applications on the top. For further details please refer to FAQ inside Settings.
# shows both CPU wakelock (Partial wakelock) and (Full wakelock) ;
# merges wakelocks of corresponding app into one expandable view for better user experience;
# currently active running applications are shown in red color;
# allows easy sorting options by Running state , Wakelock time and Alphabetical order;
How to use:
#1 Charge your phone above 90% and unplug cable (or just reboot the phone)
#2 Give it a time (1-2 hours) to accumulate some wakelock usage statistics
#3 Open “Wakelock Detector”
#4 Check the apps on the top, if they show very long wakelock usage time then you found the cause of your battery drain!
We are working on improving the performance of the “Wakelock Detector” by adding new features regarding wakelock issues users usually face. We are trying to follow up all your comments. And we know that the application is not ideal yet. We would appreciate if you send us email before giving negative comments in the Play Store. Your feedbacks are always welcome!
