The core warns us with the display, but we need the apps to also warn us of a low battery while we are playing.

We need a Verbal warning, or a visual warning in a corner of the screen, that blinks and shows when we hit 15%, 10% and 5%.

Too many times I've been in a Beat Saber Match, or a I've had a GREAT poker hand, only to have the Quest 2 shut down without ANY warning.
If I had this warning, I could connect my 10,000mAh Power Bank or Cable and not be knocked out of games and parties.

PLUS, with NO WARNING, it gets down to ZERO %, and then we have to let it charge back up for a while, even to turn it back on. So, we miss A LOT!!!

Plus, that last 15% goes faSST. With 15% and 10% warning, we can plug it in, or add the power bank and continue on.

Please Warn Us :)
