My Problem

Battery was lasting 1 to 2 hours under network use (wifi, 4g).

My Fix

Replaced the battery with one of your kits.

My Advice

The battery connector lifts up and out of the phone with the battery. It's a whole piece. The text/picture walkthrough doesn't make that super-duper clear. The video does, though, so watch the video right before doing the repair.

Very, very easy repair.
