iPhone 3GS battery replacement - went well

Meu Problema

My battery was giving me less and less time between charges.

Minha Solução

I followed the repair guide to the letter. No problems. Afterwards, I fully charged the phone, then let it discharge until it turned itself off. After a few hours at that state, I charged it again and it's back to what I remember when I first got the phone.

Meu Conselho

Follow the instructions to the letter and be very patient.
