I bought this tablet few weeks ago. Last night i put it to charger at 87% after I woke up, and looked at my tablet, it was at 77% at as hot as hell... about 70+ degrees celcius hot... i burned my hand almost. then i took the charger (stock) out and remover the usb cable (stock) from it, the plug was around 60 degrees... almost as hot as my tablet. so I turned the thing off and plugged in to another wall, now with power off, it is not hot anymore.
The battery has been so weak, i can play Brave Frontier with my iPad Mini about 8 hours, with this Nvidia Shield, around 2h and the tablet is while playing so hot ( ~60-70C), that the cover must be on the back so i can touch it. Is that normal? My phone (Z2) runs very hot (~65C) while playing this same game, but not on my old Note 2, that was cool as ice.. If i want to stream and play anything, it must be connected to a charger, then i can stream whole day, battery will last, if charging, a whole day! (It will ran out at somepoint, was at 43% from 100% after 5h of streaming live to twitch while charging) WOW! NICE NVIDIA!
