Lg v20 freezing/lag when not charging

[geloxzy19]

I been using this lg v20 for almost 3 years, and this is my only problem it gave me after those years.

Sorry for my bad english

My lg v20 had this problem just recently... Every time i unplug it from the charger it freeze if it doesnt its so laggy you cant even do anything like navigating to settings or so on... But when i plug the charger it turns back to normal... What could be the problem? ... I was thinking it was just the battery but the other one i used is just almost a week even the original battery can still last a day normal use without gaming... Is there any case out there like mine? Does it have a fix?

Btw im running los 16 + gamma v15 f800s kv

Thanks in advance

Try cleaning the USB port?

My wife's us996 had an issue and cleaning the port fixed it:

It turns out that when my phone starting to heat up its lags but when I plug the charger it turns back to normal... And also I notice there are some flickering on the screen specially on the 2nd screen

Well, to rule out a hardware issue, I would go back to a stock rom and give it a week or two to see if your issue still exists. If the issue is still there with stock, there's definitely a hardware issue, battery or otherwise.

Have you tried a battery monitoring app, like Gsam, Better battery stats, or accubattery? That could give you a clue on what's running/causing the heat issue.

I'm using accubattery and it seems there's no problem at all. My phone won't heat up unexpectedly thou but every time I play games or even doing intensive tasks that's where the problem kicks in. I also noticed while I'm tweaking at kernel auditor the CPU temp is 78c but the phone isn't that hot. Im thinking the thermal paste isn't doing its job and maybe causing the problem
