I am on Android 7.0, Dec 2016 security patch. Have not updated phone since then.
Since last night, my phone is heating up quick, battery is draining super quick, and the highest 3 items on my battery usage are "Google Services" , "Android System" and "Android OS".
Also noticed on occasion - Google Play Store is trying to install update for "Play Support Libraries".
Any idea on what my phone is trying to do? I just want to stop it, and let me use my phone again

I thought something to do with a stuck update, but restarting phone would fix that, no?
I have tried:
Restarting it..(multiple times.),
remove battery and let it sit a few mins then turned back on,
Uninstalled all google play store updates, then updated google play store
installed LG updates that were pending.
I want to try installing all updates sitting in the play store..... but not sure that would make a difference. I am not on WIFI atm, and its taking a very long time to install each update.
