Firstly do not just watch the video if you are going to do the battery replacement. I was too busy and stupid and only watched the video and boogered my Girlfiends 5S with the screw replacement boon doggle... You must read the iFix full instructions (forget the video) or you will screw it up!.. It is not necessary to take the screen completely off. I did my 5 that was and assumed the 5S had a different protocol for a reason. It doesn't require removing the creen at all. I was careful on my 5 and had no problem. I took different prcautions and watched only the video and screwed up a perfectly good 5S... This means if your not backed up you just lost all your contacts and messages videos etc.... iFix is cool except their Video is not concise like the long instructions they provide. I was stupid and figured I new what i was doing after doing a couple other batteries and bingo I screwed it...
