But I guess not many people are having that problem and I don't have the patience to test any more, so I'll just leave it there. FlatUI looks awesome but stock isn't horrible I guess.
The problem could be in the charger itself.
Charging current is proportional to the charge voltage. So 5V gives a low charge current (15% per 8 hours). But 5.3V gives about 2.2A of positive battery current.
Our chargers is 5.3V normally. Please check yours under load.
