Review: Look at the videos and take your time! - I thought my phone battery was getting a bit weak. I watched a couple of YouTube videos and it looked pretty easy to replace to me. I would give this task a 3 star out of 5 on the difficulty chart. I've always done this kind if stuff myself. I'm getting a little older now so working with such small electronics you need to make sure you have good eye sight of good glasses. Look at one of the videos and take your time, no rushing. Especially trying to get the glue loose from the battery, that is the toughest part.
Review: 30 days almost 30% battery degraded! Junk - One month after installing the battery health is at 75% almost the same as the own one i replaced that's several years old. Very disappointing
