Phone is four years old. This is the second time the battery, which was about two years old, needed replaced.
The instructions made it easy to replace.
The battery seems to work well. Also, the battery shipped and arrived very quickly. Items were well packaged and protected during transit. Tools worked great. Box serves as a handy case for storing. Thank you!
P.S. I tried to update the phone's software about 10 months later. I got the error code 29 only I do not have the original battery anymore. The phone can no longer be used until I can try to replace this ifixit one with an original one just for the restore.
