First time ever repair of an iPhone: battery replacement on my iPhone 3GS
20 - 30 minuten
The battery of my iPhone 3GS was running low very quick so I decided to replace the battery with a fresh one.
First, I took my time to read through the ifixit guide and watched a few Youtube repair videos. When the package arrived I searched myself a quiet place, prepped everything, took a deep breath and started my project.
The repair itself is fairly easy to do once you got everything prepared. Don't hesitate to take a break when you're getting too nervous.
1. Make a rough drawing of the iPhone and mark the screw spots with an X (use a pencil). Everytime you take out a screw put it one the X-marks. This will make the reassembly process much easier.
2. Fasten annoying cables with a little piece of sticky-tape
3. If you use a spudger to disconnect the connectors, start prying as far away as can from little components on the logic board.
4. The Youtube channel LE55SONS uploaded a very good battery replacement video for the 3GS. The video helped me a lot especially during the reassembly of the phone.
