Chosen Solution
Hello, I have an iPhone 6s which is always warm when not completely turned off (even after multiple reinstalls via iTunes) so the battery empties after 5-6 hours in standby. Besides that the battery actually is pretty weak, the phone gets warm at a specific spot, which is beneath the mainboard protection plate below the display connectors. Since I don’t want to risk destroying the mainboard with desoldering the plates, I wanted to ask if this is a common problem/spot and if changing the battery could even be the solution of this problem? If not, it would be nice if someone could give me an advice which chip or part is possibly causing the warming of the device. I am asking because I don’t want to throw more money at this phone when it isn’t solving anything, so please excuse me if similar topics have already been published, I just haven’t red exactly my problem so far. Thank you very much for your help Update (22.11.2018)
Hi, thanks for all of your help. I’ve made some further investigations and found out that the Home Button (not the Home Button extension cable) is guilty. Does anybody know if there are any Home Button relatable components beneath the protection shield over the sim card tray? Or is the warming even possibly caused by the Home Button itself? Unfortunately I have no way to test this right now and before buying a new Home Button I wanted to ask if it would make any sense.
When there’s excessive heat and battery drains fast you have a short to ground that drives current where it shouldn’t go. Right below the connectors the shield covers the Cpu but also a number of other capacitors and screen drivers. I’d try running the phone without display connected to understand if screen is causing some issue..if excessive heat disappears it might be you have a short caused by the screen and a replacement should be considered..did it get hit badly at some point ? If you still got overheating without screen attached, in the same area, unless you’re a technician there’s not much you may achieve by removing that shield except damaging the phone beyond repair.
