Hello, so sorry to hear about your issue. This is actually a common issue among the iPhone 6s plus. I personally had a very similar issue with the same phone, mine just completely shut off and would not come back on. All i did was take it to apple, they took the phone in and with in 3 days, i had received a brand new iPhone 6s plus in the mail. These kind of issues are technically not fixable just yet, so your best bet is to take it to your nearest apple store, or call them and send it in. Regardless of the warranty being out, this is not your fault, and they have to replace it. Hope this was of some help. Have a good day!
