iPhone 3GS Battery
Update: I had to do two of these, and it didn’t take me any longer than 10 minutes for either one of them. Easy peasy, thanks for the clear and concise guide.
Thanks for this guide Maximilian, and also for the link to purchase the battery, commenter Jorge! Those batteries seem to be pretty difficult to find online. Amazon definitely doesn’t make it easy to find them even on their own site, though they seem happy to sell a replacement fire… :)
During reassembly: be aware that the replacement antenna connector (the one that comes as part of the lightning port assembly) might be a very snug fit here. It probably took me close to 10 minutes to get mine on. Thankfully the little sucker is stronger than it looks, or else I would have smushed it flat multiple times. You’ll know that you finally have it when it lightly snaps in place.
