Trouble charging since update

I noticed a new problem yesterday, but now as well. My phone has a hard time charging. I plug the charger in, but instead of a lightning bolt next to the battery showing that it's charging, the battery is red with an exclamation mark and doesn't charge. It's charging now though. But that is becoming a hassle. This has not happened before 10.2.1. Battery guru picks up a charger. It says "TypeBCharger" but in red.

Also, my phone is running quite hot with Android apps. Battery Guru shows 42c atm, and I can feel it. Is this normal now?

I am using an STL100-1 with the official 10.2.1.537.

Has anyone seen this issue, or know what causes it

That does not sound correct. Have you restarted (below)? What Android apps? You might want to reload the OS.

Try a restart:

Press and HOLD both Vol Up/Down buttons. Keep holding while the screen goes fully black (ignore the screenshot), keep holding through the Black/White logo and when the Colored Logo shows up, release those buttons.

If you have the STL100-1 variant the volume button reset method doesn't work. In that case, Press and HOLD the Power On Button until you see the LOGO as above
