How can I fix my HTC Desire 626?

[AC Question]

I had this phone for a while now (around 7 months to a year) and it was only recently when it wouldn't function properly. The first thing I noticed was that for example, I would watch Youtube when the phone is on 97% and all of a sudden, the battery bar at the top would blink red, say that it's at 0% and turn off by itself. If I turn it on after, either it would repeat the same or function like normal at the percentage it was on. Next problem, there is no guarantee that it will turn on. I would turn my phone on and it will boot up and it will black out, stopping everything. I would try turning it on and the same thing happens. Last problem sort of like the first, I would mind my on business while using the phone and the screen blacks out and the orange LED light used for charging will come on, even though it isn't plugged up at all. I can't press any button to restart, can't change the volume nothing. It's just black.
