Iphone 6S Plus. Previous battery was up for replacement so got a new one and also a new screen. Replaced both but now I have the following: without lightning connection switch on, shows phone needs to be chargedplug in lightning, shows battery is charging (minor red bar icon) when try to switch on the phonestays like this, no progress even after hrsdisconnect battery, measures 3.48V at the battery sideconnect lightning (with battery disconnected), measures 3.69V at the battery connector (phone side) but only for 12sec, then drops to 0 for 1 sec and then comes backswitching on the phone with battery disconnect but lightning connected shows black with white apple logo for the same 12sec as above, then drops and continues to cycle I was wondering, as I have reseated all connectors at least 3 times, inspected them all look ok, all right screws in the right places and don’t think to have damaged anything, all parts looking OK … will it only charge properly when it’s closed up ? There’s this gold plated pin connection on the phone side where the touch button comes when closed, does it serve as some kind of open/close break circuit maybe, that prevents charging when not closed ?
If not, what else should I check ? Battery connector area:
I’am sure a new battery will solved your problem, this is the first step you need to try.
It will charge when the screen is open. Have you tried hooking up the original battery to see if it affects it?
