Product:
Samsung Galaxy J3 2016 battery (2600 mAh 3.8 V)
About the product:
I have bought cheaper phone batteries on the internet before, but they have never been as good as the original battery. The battery I got from Battery Upgrade however, whilst more expensive, is of much better quality, and is at least as good as the original, if not better.
