Almost like a brand new phone

Meu Problema

The original phone battery was dying, so I had it replaced but the replacement battery seemed to perform even worse than the original, and had degraded to the point where the phone would die at 30-40% battery if I did anything CPU intensive.

Minha Solução

Replacing the battery was very straightforward. The most difficult part was keeping track of the tiny screws. Battery life is about 8 hours now, and after finally upgrading to iOS 10, it's almost like having a brand new phone.

Meu Conselho

Be careful with the screws, they're incredibly small and easy to lose.
