Naturally when I got the phone it was at a 60% charge. I drained that in 30 min. Then did the typical plug into charger at 2% and charge fully then drain again to 2% and fully charge again and im noticing better battery life. Guess do this 5 to 6 times. I did this on my s3 and note 2 bu5 never noticed a difference. And im an extremely heavy user. I use about 20gig or more of data a month
