Good morning. I was going to replace the battery in my daughter's Iphone XR and ordered a battery kit from iFixit. I had replaced batteries in some of the older phones for the kids over the years so thought it would be no big deal to do this one until I looked at the instructions. I looked online and Best buy will replace it for $49 which isn't much more than I paid for the kit so I sent the kit back and told my daughter to just take it to best buy when she gets a chance. There are a lot of things that have to be taken apart to change the battery and some of the screws are different lengths so if you get screws in the wrong place then you could damage the phone. Not to mention that the screws are so small that I can barely see them with my old eyes.
