iPhone 7 died and won't restart - shows charging dead battery screen
My iPhone won't turn back on. It died and I plugged it back in, but it shows a dead battery (no chord, I get that when I unplug). I have tried multiple chargers and ones I know work, so it must be a problem with the phone? It's been plugged into the wall for an hour now. If I press the power button, it shows the battery again. I've tried resetting it by pressing the power button and down volume, but it just shows the battery again. Please help!
iPhone 7, iOS 11.4, null
