Reminds me of a battle I endured between a portable generator and a UPS. (long story)

Try charging it while it's turned off.

Plan a trip to where you buy new cell phones.

Haha yea that's exactly what I did. Just kind of a funny experience. You'd think somebody would've programmed the thing to stop beeping/vibrating/otherwise wasting battery power when it got that low.
I am still rocking a Galaxy S5, think they're up to S11 or S12 now. Really don't want to spend the money because it still does what I need it to do, namely phone/text/internet.

Usually there is an option in the settings to turn off vibration mode. The one in my old LG phone buzzes anyway, so I did some surgery and performed a motor-dectonomy. No more vibration, no more power wasted prematurely.

Buy an iPhone. It just works.
