Apple's new smartphones have always been the talk of the town and this year was no exception with release of the highly anticipated iPhone 6s and 6s Plus upgrades. However, the excitement is not living upto the expectation for many as their brand new, sparkling iPhone6s has started to power down without any reason. Many users on Reddit and Apple Support Forums have now started to report this bug where their phones are getting powered-off when left unattended for some time.
Some users also noticed their iPhone 6s home button feels warm citing some kind of overheating problem to the issue, any of this is yet to be acknowledged or fixed by Apple. After the phone shutdown due to this issue, the only way to revive the device back on is to hold the power and home button down for 10 seconds, forcing the phone to restart. One user on Reddit seems to have solved the issue permanently as follows:
I ended up solving it (or so I think), by completely wiping my phone and restoring from my iCloud backup. I also was using my old 6 Plus charger and cable and swapped that out with the one that came with my 6S Plus. I'm not sure if that had anything to do with it, but for me this issue only happened at some point in the night when it was on the charger.
