My iphone 6s plus died and now its been two day on the charger
What can I do to get my iphone 6s plus to come on after it died and won't charge up after two day on the charger without spending money on getting it repair.?? I put it on the charger at 5% of batter life & it said it was charging, but after an hour or so of checking it, the phone was dead & it never came back on.. About every hour or less the batter showing red would pop up on the phone as if it would be trying to charge, but it would go away & nothing would happen.. Its been two days & my phone still won't come on, what can I do myself to fix it to get it to cut back on because I can't afford to get a new one right now or pay to get it fix.??
