Smooth Battery upgrade

我的问题

My battery was running at 20% capacity after 3 years

我的修理方法

Smooth until I get to the removal of the glue behind the old battery. One of the adhesive bands broke and I couldn't reach it. Best of advice warm the back of your iPhone with a hair dryer before you try to remove the bands, the will make your job much easier.

我的建议

I follow the tutorial on ifixit but they do not have the reverse steps.
