I've just completed the replacement and want to thank you for that guide. It was very useful. Especially thanks for noting the screws lengths - this was super helpful!

A few things I would add here for those who are completing this task:
1) Pull Tabs can really break off. Be careful with those and if you break those - use a credit card or a similar object to life the old battery. Honestly, that was the only way I was able to remove the battery.
2) Do some screws management and have a nice area to work on. It took me some time to actually screw those back in place.
3) Power on your phone after you connect all the cable and before you re-assemble. Just make sure that it powers on. That power cable takes some time to plug into and any minor movement disconnects it. That's why we need to make sure that phone powers on.
4) Check that camera works, button, operate etc after you turned it on.
5) If all good - assemble. You phone is back to being a brand new. iPhone 8 in 2021? No problem!

I really appreciated the straight forward detailed instructions. I was no where near as smooth as you, though I doubt this was your first time. I launched one of the screws across the table during reassembling and was blessed when my wife actually found it. In the end the phone is up and working so thank you very much

Thank you for stating where the screws went specifically the size relative to their placement.

You're the only person who ever mentions that Apple uses screws of all different lengths on the shields, so you can put them back in the right place. Thanks for that.

Thanks to you I probably saved 100 bucks by replacing my battery myself and it was a good explanation of where the screws were as well. Thank you

This is an easy job other than removing the old battery. Had to carefully pry it out. Entire job takes about 30 mins. Screws are small so be careful and watch the different length screws, as noted in this video. Since you may damage the old battery removing it, I recommend running the phone until it’s discharged before starting.

Phone came apart with no trouble. Had trouble with tearing of the strips on battery but was able to pull battery loose with no problem. It went together easily except for water proof strips that came with battery kit didn't stick well. Phone works great again! Video was very helpful.

One comment a would like to make regarding this is it seems the lcd connector can be reseated wrong, reseated it about 10 times and still no picture, thought for sure i had damaged the flex cables even though i was super careful, turns out though that you should try to reseat it as far to the left as possible.

Brilliantly explained step by step iPhone battery replacement.

This guy made it look so easy. I'm a bit of a moron so it took me a couple hours to swap the battery...

[stevedent]

Thank you for providing a thorough tutorial for the iphone 8 battery replacement!. It helped me through my first phone battery replacement.

[dibjr]

Just a bit of advice. Remove the battery connection first. That will keep you from doing any unintentional arc welding.

When I replaced my screen for my iPhone SE (2020), your video and demo were super helpful for me. They gave me the confidence to undertake this repair as well as the appropriate instructions to repair my phone properly. Thanks so much for posting!

Best disassembly video I’ve seen for this phone

[LorenKerns]

This guide was a perfect guide. Easy to follow step by step.

[jahidjp]

Just upgraded mine by following this video, very helpful with all the details

[stevecrocker]

good that you mentioned the different screw lengths. Many people don't look carefully at what they take out (and compare with others they have taken out) so they get themselves into a jam
