If you’re someone who likes to plug in your Android device just before you go to bed, so that you have a fully charged phone when you wake up in the morning, then you might not want to get woken up by the battery full notification.
XDA forum member the3dman wanted to stop the alert going off in the middle of the night and has written a fix to deal with the issue.
Currently the fix stops the alert and sound but the screen still comes on when fully charged. The dev is still working on identifying what it is that is still calling on the popup xml once the battery reaches 100% and as such the fix is in alpha.
Other know issues are that the phone may soft reboot twice then return to normal.
If you would like to try out the fix and provide feedback, take a look at the application thread. the3dman has also provided the relevant update.zip file for those who wish to return to stock after trying out the fix._________
