view story

http://androidforums.com – Hi, I have bought an s2 I9100t in Australia and ever since I've had it whenever I try and charge the battery it says 'charging paused battery either too hot or too cold.' after just a few seconds. Even when im not charging the phone it heats up alot on the side with the power button, and obviously gets worse when plugged in. The battery runs down very quickly aswel and the only way I can charge it is to put the battery into another phone. I have already replaced the charging port as of yesterday and it is still having the same problems. I've been trying to factory reset the phone (General)
