I'm sorry to hear your phone is not running correctly. I'd suggest watching a full tear down and reassembly video on YouTube or a reputable tutorial site and see if you can pinpoint any missed connections or pinched components.

The reddit group r/mobilerepair is also a great resource and may be able to help you diagnose your problem.

Very frustrating that a year and a half later the tutorial has not been fixed to include the information you've given, or any more information at all.

It's clear that this tutorial is not complete when multiple replies have had issues with vibration, screens, and other functions, along with pieces that got left out upon reassembly. I had better hopes for ifixit since they offer a complete kit and boast they have tutorials. I thought the experience would be higher quality.

I am thankful this is not my first battery replacement because this guide is not for beginners. I commented above with specific info, but overall I've never seen a tutorial that gives an ok teardown and then just says to do the reverse.

Nothing about how to prep surfaces prior to putting things back. No warning about pinch points. No instructions on how to apply the new graphite stickers or the adhesive. I had a rubber piece fall out while I was taking the battery out. There was no clear diagram so I had to hunt to find a pic with the piece in it. It did end belonging where I thought it did, but a lot of times people in competent tutorials will point out all of the loose things that may come out. Nothing about how you clean the glass on the camera in case you accidentally got fuzz or smudges on it before you seal your phone back up. Nothing about safe handling of the display (copper sticker has some marks on it, I was hoping it didn't affect my display but not addressed. It seems ok so far). Disappointing.

This is a frustrating step since I bought the kit thinking I had everything I needed. I don't keep 90% isopropyl alcohol on hand (71% is effective as a disinfectant, where as 90% is not).

For those who also do not have 90% on hand, I was able to just gently lift the battery out without the alcohol and the graphite under the battery remained in perfect condition and did not tear at all.

"Shallow" is not a very helpful descriptor for the angle, nor do any of the pictures demonstrate what they meant.

Instead of pulling straight up, try pulling as parallel to your work surface as possible. It's like removing Command hooks.

I had to fish around for this tab. It was not as easy to find as the last.

Would have been much more helpful to start off by saying to be careful removing this piece so you can reuse.

Also would have been helpful to say that the kit comes with a new one, so don't worry about saving it.
