55 minutos - 1 hora
The phone would not hold a charge more than a few minutes but worked otherwise.
The battery arrived quickly and fit perfectly. The repair was done in 40 min without a major hitch. It's running perfectly now.
Only one small hitch. One of the screws on the circuit board is covered with a "Do not remove" label which doesn't appear in your video. Consequently I spent awhile trying to understand why the board wouldn't lift until I peeled away the label and found the 7th screw. It would be a good thing to tell people that in the video but otherwise it went well. The how-to video is a life-saver.
