While updating to the latest beta build of iOS 11 (11.1 beta 3), my phone starts overheating, never completes the install (it appears very close to complete) and eventually drains itself to the point of turning off.
Latest update (11.1 beta 3) never finishes installing.
Just for reference, I've tried hard reseting and restarting the install, as well as fully charging it before trying it again (and keeping it connected to power the whole while).
