Re: Samsung low battery temperature

Welcome to Android Central! That's often a sign of a failing battery. But it might be some malfunctioning app as well. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

The best way to fix it is to turn it off, take the back off, unplug the battery for a few minutes, plug it back in, and restart the device. I was going to buy a new battery, watched a YouTube video on how to do it. I practiced by unplugging the battery before I bought a new one. After my practice run, my Note 8 has worked great with no battery issues. I plan to do that occasionally just for maintenance! Saved me from buying a battery!
