My iPhone 4S is ~2.5 years old and it no longer seems to charge or hold a charge. I can leave it plugged in for a day or more and it will only charge 3-5% or it'll actually start to **lose** charge while plugged in. It'll also lose charge if I start doing anything while it's plugged in, like messenging or reddit. It also frequently disconnects/reconnects with my computer and my friend's computers as well as the wall socket and iTunes gives the error message: 0xE8000084 I had the battery replaced on Saturday but the problem still happens. I restored it to factory settings and set it up as a new phone, but it still won't hold a charge. I've also tried: switching power chords, switching which USB socket it's plugged into on my computer I posted somewhere else and someone told me that they thought it was a logic board failure. If it is, what're my options? From googling round it seems like I'm SOL... Any help would be super appreciated.
