Just like the title says, this has been happening ever since I bought the phone in December, I have reset the phone to stock to see if it was maybe caused by some third party app, but it still does it. It usually happens at night, and when I pick it up in the morning the notification light is usually still blinking, but it won't respond to the power button I usually have to volume down and hold power for ten seconds in order to restart it and when I do the battery is usually at around 20% or less. I always check my battery usage but it all seems normal, usually it says screen time and phone idle are the main consumers. This happens maybe 2-3 times a week, and some times it only happens once a month. Does anyone know if this is hardware or software?
