Wakelock Detector FULL PACK unlocks all features (Widgets, Knowledge Base). Requires ROOT Access in Android 4.4 KitKat or later.
Ever wondered why your smartphone screen does not 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 keeps 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 the CPU awake (Partial wakelock) and keep the screen on(Full wakelock). Applications that use wake lock privilege improperly leads to situations where the CPU or phone screen stays active without the user’s knowledge and thus causing dramatic battery drain.
“Wakelock Detector” shows wakelock usage statistics for all applications, whichever held wakelock since boot. By default, it displays CPU wake-locks 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.
