A client recently had their iPhone 6S Battery replaced after it reported it to be “Service” in the Battery menu option in Settings. After battery was replaced from another store, after 1 month, battery level would jump erratically from 10% to 20% then 100% and would only last half a day at best.
After we inspected the battery, it’s actually a fake Apple battery. The colouring and font are off and not same as the original.
We don’t sell Original Apple Battery as Apple does not sell to public spare parts, we do however install high quality after market batteries. We installed our battery and after testing for a day charge and discharge levels, the client would have a great time using their new like phone again.
