I have had my G3 since T-Mobile released them and have had excellent battery life and no heat issues until last night and all day today. Today it was very hot to the touch and my battery was only lasting three hours. It was so bad that even connected to the charger it was still dropping percentage points! So I used android tuner to log who was running and it showed only the Android system running but it was at 100% I also remembered seeing the process .gapps stopped message. So I went ahead and did the download manager app disable/clear/enable routine and sure enough my heat issue and bad battery life problems disappeared immediately. Back to being a happy G3 user again.
