So I got my Note 7 a couple days ago, and was able to perform the update with no issues. However, last night the phone began to power down on its own and cannot be turned back on without the power cable. So far, there have been six incidents and on all instances the battery power was at over 90%.The sad thing is that the original Note 7 was working perfectly. Has anyone had any issues with their new Note 7 powering down on its own?
