10 - 30 minuten
My I-phone 4s battery wouldn't hold a charge.
I watched a YouTube video before starting the repair. I wasn't anticipating the tiny metal ground becoming detached when I removed the screw inside the phone to remove the old battery. Luckily it popped up and onto the table I was working on and didn't get lost. I did have to use a magnifying glass to work with all the tiny screws. I ordered the fix it kit and was glad that there seemed to be a little magnetism from the screwdrivers and the screws otherwise I don't think I would have been able to get the screws back into their tiny holes. It still took me about 40 minutes however to
get the little ground back in place and everything put together again. I'd never had the back off my phone and used rubber gloves to push the back open. My bare hands were too slippery to get it to budge.
Definitely do this repair on a cloth or in a shallow pan so you don't lose the tiny parts. Magnifying glasses would be very helpful along with tiny tweezers or forceps. Don't mix up the screws. They are different sizes
