First timer

問題

Battery started to behave random, and no recall from Apple, also because I totally enjoy fixing

修理

Smooth until the adhesive it almost became a failure, used dental floss to finish the job

アドバイス

The guide doesn't stress the way you should be tearing the adhesive strip properly: flat, and towards the speaker on the right, and towards the 3.5 jack on the left, then move up as the strip looks (and feels) thinner and resists the tearing

Also remember to purchase the adhesive strips, the tools guide doesn't name them
