try a new battery
Iím recently looking for Note 3 backup battery for my friend and had luckily come across posts reviewing nice batteries I assume made in china while searching on Google. I decided to buy one from mpj for my Google Nexus S first. Received the battery several day ago, did a calibration---used the battery till its empty then charge it from empty to full. Have to admit its unexpected good. With same dimensions like the stock but gives me several hours more before it died. I have been stuck with the original batteries for years but now I begin to trust the Chinese suppliers who I always had believed were scammers.
