Hello, I replaced the battery in an IPhone 6S last night. I followed the instructions by discharging below 10% and charged the phone overnight. The level of charge displayed never got above 28% now it seems to jump up and down and the phone resets itself frequently.
By seeing this might be battery not properly connected on battery connector.Check it first if the problem still same try to replace battery with new one.
I suppose you did everything the right way? You did shut down the iPhone before opening it and getting in there with a screwdriver?
Thanks for the suggestions. It was a faulty battery. I was able to install the original one as a stop gap until I get a replacement. It wasn’t holding a charge well before the replacement but it’s functional.
