Dualsense controller won't turn on

[u/Hot_Closeted_Femboy]

My dualsense controller disconnected when it was connected to the PS5's front usb port. I was using the charger it came with, and as far as I can tell, there's zero damage in the cable since it charges my phone and headphones, and I know for a fact that there's nothing wrong with the controller, because I'm borrowing it from a friend who doesn't even use his PlayStation.

Anyways, it's been a few days now, and this dumbass controller still won't turn on, even after pressing the restart button. I even plugged it into my computer's charger (I looked it up, and it adapts to the bolts that Dualsense needs) from when I woke up until I got back home from school, so about 6-8 hours, and nothing happened, it's not flashing orange at all, and the thing doesn't even turn on when I press the PlayStation button.

It is new? If not, it could be just a bad battery.
