I posted a question on here I think about a iPhone 6 Gold on iOS 8 that will not turn on. it has been sometime since then and now a iPhone 6 Plus Gold I bought on iOS 8 will not turn on, so it says low battery, then the Apple logo for a few minutes, then it turneds off. i believe it might need a new battery. If there is any thing else I should do please tell me. thanks!
I would try to replace the battery first and if that doesn’t work next would trying to wipe the iPhone because it could be a problem with a corrupted os not being able to optimize the battery correctly
