The phone would sometimes be dead in the morning, even though at night it showed about 50% remaining.
It was a little nerve-wracking, especially when removing the battery - the adhesive breaking loose make sounds like the phone was cracking. Getting the last removed/first connected ribbon cable on the display was a pain.
My only negative is that you folks don't provide battery recycling.
1. Do it with plenty of light.
2. When removing the last ribbon cable that connects the display to the motherboard, note HOW FAR the ribbon cable is inserted, so you don't drive yourself crazy wondering if you've got it in the right place when you put it back. This is really the only time a third hand would be helpful.
