This issue arises when the battery gets below 15% and I get the Low battery notification, and after that, the CPU does not go to DeepSleep anymore, it stays in the 200MHz area.
The only procedure that will stop the "fuel alert" process is by restoring or by wiping cache partition in recovery mode or removing the battery and attaching it back. After that, everything works fine until the next 15% battery notification
After the 15 % battery notification, it never goes into deep sleep and always stay awake
Charging the phone does not help. After the phone is fully charged and after I disconnect the cable, the CPU continues to stay in the 200MHz area according to cpy spy .Thus I will never get a DeepSleep again, no matter what I'm doing.
I have 4.2.1 jellybean && linux kernal version 3.4.5 . I have only 3-4 app installed including whatsapp that all and my WiFi ,GPS are always off
Does anybody has any idea what shall I do. And why is this happening so? Of course I can charge the phone before getting below 15% but this is not always possible.
