My extended battery just came in the other day and I was happy due to the fact my stock was becoming so bad. My question though is how do I calibrate it properly, I'm getting a few extra hours now but I was wondering I would be able to get even more hours with the battery? Yesterday I got about the same amount I would with my stock and today I'm getting a bit more How long does it take? Am I on the right path or not? Thanks in advance!
