Problem with new battery, iPhone working only with power supply
I have this old Iphone4, whose battery was dead with. So I ordered a new one and changed it by myself (which worked flawlessly). I had first to load the battery before the phone would turn on again. Now it works again, all the apps do function, and everything seams fine.
But now I have this issue: the iphone stays on only if the power supply plug is connected to it. As soon as I disconnect the power plug, the phone shuts down. I tried a reset/forced start (by holding both upper and front buttons together), but this helped neither.
I checked again, if I mounted the battery wrong, but everything was fine, and looked in place.
What is causing this strange problem? Do anybody help ever experience anything similar? Thanks for your help.
I have this battery check app, which tells me the new battery is good, only just a little bit below full capacity. But the readings are a bit strange now that I see:
Battery Health: Good 1305/1420mAh (92%)
Current Capacity: 1340/1305 mAh (100%) (this is strange.... how can the actualy CC higher than the available CC???)
Es esta una buena pregunta?
