Wife's iPhone 5 needed a new battery. Phone still had original battery
I ordered the battery replacement kit from ifixit.com, took a week to get it, not too bad. I re-watched the how to video on ifixit.com and proceeded to do exactly as the video said to do. The hardest part (probably because I was being so cautious) was lifting up the screen then getting the plastic pry tool under the screen to pry it free from the clips. Once I was able to get the pry tool under the screen it released from the case as expected. The second hardest part, again because I was being very cautious not to apply pressure to sensitive parts, was taking out the battery itself as it is clued in or something. After removing the battery it sorta looks like double sided tape.
I installed the new battery, connected it, then the screen, reconnected the plate covers for the battery wire and screen wires and resealed the phone. Turned it on and tested it, working great with the new battery.
Total time was about 45 minutes.. not too bad for my first time :)
This was my first time visiting ifixit.com and first purchase. I would highly recommend anyone with an iPhone, iPod, etc and needs to change the battery, screen, etc... get your parts here and watch the how to videos. The videos take you step by step on how to open these things :)
