Don't be frightened!

내 문제

The battery depleted quickly, it was almost 3 years old.

나의 수리

No problems. The guide was easy to follow and I was done in under 10 minutes. The longest part of the fix was prying out the original battery. I could probably do it in under 5 minutes next time.

If you are thinking about replacing your battery, just do it. Ifixit cost less than a third of Apple replacing the battery and I didn't have to wait an hour.
