I spent about 2 hours and 40 minutes to replace the battery and reassemble the back panel.

Taking out the battery and removing the adhesive took the longest. Also, keeping the back panel connector secured while putting the screws was hard. I had to hold the cover from closing while putting the screws on with the other hand.

Overall, this guide helped a lot and I couldn't have done without it.

It was fun and nerve-racking at the same time. I'm glad I tried to change my own battery and it's working great! I added a few of my comments in the guide and hope it helps.

That was a good call! Thanks!

During reassembly, make sure to firmly connect this back panel connector.

I had to hold the back panel close to the phone so that the connector stays connected, while putting back all the screws.

FYI the kit includes a new adhesive tapes for the battery. I only found out because I looked inside the kit.

I carefully pulled up the battery from the bottom using the opening pick because my adhesive pull tabs snapped. The battery was so strongly glued to the bottom. I needed to use the other tools in the box to really push the battery out. Could not do it that gently. But anyway succeeded! v
