Review: Good price and works great so far. - Price was right and the battery arrived with everything needed to do the replacement, and then some. I think I only used about a third of the tools that were included. The battery was about half charged out of the box and has taken a full charge and has worked great since it was installed about a week ago.
Review: Nice battery for temporary repair - Works well very easy to replace and it fit right into the phone i was able to fix my boot loop pretty quick and easy I will say it’s only for temporary repairs I would use the Battery as a complete replacement since it’s not an official battery there were no issues with other components getting corrupted but it does overheat after a few hours of using the phone but that’s completely normal with the model
