hello everyone i have battery life issues with my device my battery was drain so fast during stanby and the device warm even i not used it. it drain from 80%-20% overnight (stanby,airplane mode) when the battery low and the device goes turn off automatically it won’t boot again even i charge it. i try to recharge the battery on another device until 50% then i installed the battery on my device again. and now my device can booting up i already try to replaced with new battery, but still same.. battery drain fast and the device heated even i not used it my question is, it have problem on the logic board? or software problem?
All symptoms seem to point to an IC failure on the logic board, probably the one exchanging data between battery and power components. That can be caused by non original chargers/cables and bad hits. If any of these apply to your case, that’s most probably how things went with your iPhone. There’s nothing to do besides finding a microsoldering technician who can fix the logic board, providing it makes sense from an economical point of view.
