The charging speed is really slow (it takes more than 6 hour for 20-100%). The input is around 200ma even the + icon already appear. However, the speed still normal when the phone turned off (so there's nothing wrong with hardware). The temperature always high (never below 44 C). The battery backup decrease (SOT around 5 hour). It's all starting happen after last OTA (.073), so I guess it's definitely software issue.
