Everything was going fine until I tried to use my adhesive strips. I was sent the bad strips on Dec 12 as mentioned above. The strips are welded to the blue tape and can’t be removed without ruining them. IFixIt - please fix this quality control issue. It is terrible to have your phone all opened up with the old battery out to realize you can’t use the new strips. I was very pleased that I live very near the iFixIt headquarters and got fantastic service from an employee at the facility to quickly replace it. But this won’t work for 99.99% of others with the problem who will be stuck waiting for a replacement.

I saw it mentioned somewhere, but be very careful of wedging the credit card at the top side of the battery. There is a flat cable for the volume buttons that I almost scraped off and almost damaged. I would have liked to see a picture of what it looked like without the battery to see that.

I have done an iPhone 5s and iPhone 6 battery. I can tell you that the adhesive strips sometimes break but when they are going to come out it is best done just by pulling straight out from the bottom. It is better to keep the adhesive strip straight so it does not crimp and the adhesive pulls off equally along the strip. I would not try the pulling from the sides as shown in the video. 3 out of 4 of the strips came out very nicely that way. Also keep re-grabbing the adhesive as close to the battery as you can get it. And go slow. The whole repair is a ton easier if you can pull the strips out without them tearing.

Pre-bend the new battery connector cable! If doing this again I would make sure I had pre-bent the connector cable the same way as the original battery is bent. I did not and then once the new battery was glued down I could not get at it well to bend it properly. I had to wedge the extra cable in a bit and then the very small extra thickness left a small color distortion on the screen due to the additional pressure on the back of the display.
