Re: how do i open phone to rmove battery
Hi and welcome to iMore.
I'm not going to advise you on that as if you do it wrong, I don't want to be held liable for any damage. However, there are loads of videos on YouTube that will tell you how to do it.
Be aware first though that by doing this you accept all risks that you may stuff your phone up completely if you do it wrong.
Personally, my first port of call in this situation would always be Apple.
