Update : Having tried literally everything on day 1, including different charging ports, USB ports and such (was full battery when it died anyway), pressing every button combination, giving it a light slap around and such, nothing worked to turn the unit back on. There wasn't even the red LED indicator for the device as charging.
I then left the unit on my table for a few days and did literally did not touch it, until today I picked it up again and plugged it into a charging port. I caught a glimpse of the red LED indicator and my hopes skyrocketed seeing as if the unit was going to work again, which after giving it some gentle taps, viola, it turned on!
A new problem then arose. The unit started turning itself on and off for no reason at all. I managed to get a factory reset in and such, but that didn't fix anything. It would randomly turn on and off in my hand, or when I put it back down on my table, until I started noticing more-or-less of a trend... the unit turns off more so during any sort of impact.
I confirmed this by mildly slapping the back of the unit a few times, and then the unit would turn off and immediately on again as if it is restarting. Unfortunately I cannot upload videos here or I will show this, but at this point I believe the battery or battery ribbon inside the unit is loose, or a bad solder joint is present, something to do with the powering circuitry is causing the issue.
If on regular units with high build tolerance, I'd probably have to physically break the unit before it encounters a power issue like what I am experiencing.
Thankfully, I believe I will be getting a replacement unit sent in exchange for this one.
If anyone encounters a similar issue in the future, this could be the case.
