Simple and Easy

問題

My iPhone 4 has been in use for years, to the point where the battery only lasted a few hours on a charge.

修理

Piece of cake, had the new battery installed before the first cup of coffee of the day.

アドバイス

The "liberation" screws provided in the kit was rather pointless... I did not have a phillips screwdriver small enough to use them. But since the kit came with the Pentalobe screwdriver, I simply reinstalled the factory screws and finished the battery swap.
