iPhone 6s+ won't turn on or charge

I left my iPhone on the charger overnight like I always do. It has the current (can't turn on to give you the version) iOS. There's nothing wrong with the cable and I have tried several. My IPhone is in excellent physical condition and never been dropped or exposed to any moisture. The charging port on the phone looks fine and accepts the cable without issue. I'm unable to get any response whatsoever from the phone. It won't acknowledge a charge attempt from either my low-watt or hi-watt charger or computer. I've owned quite a few Apple devices over the years and see my share of deaths, but never had one croak out of the blue and become completly unresponsive. IS there a chance my NEW iPhone 6s Plus has just completly died after only four months while being treated like a new baby? I haven't so much as dropped it an inch on soft carpet. I am a disabled paraplegic and a trip into a store is a major production. Any ideas? **********.com
