What is up with my phone?

[AC Question]

A lot of things are wrong with my phone and I need some help fixing my battery life is draining super fast, in an hour it goes from 100% to 30%. Also when I tried to clear the partition it doesn't work, my bootloader is completely broken. When I try to update my phones Software it just boots into bootloader and then reboots my phone, same when I try to factory data reset. once I click recovery, or anything past the second screen of bootloader it just takes me back to the first page of it.
