I've turned on fast charging and super fast charging, and I've turned off battery saver so that my phone should charge to 100%.  

When my phone is plugged into any charger or power source it crashes around 79 to 85% (it varies).  The cable doesn't seem to matter.  The charger doesn't seem to make a difference.  

When it crashes, it shows the grey charging circle instead of the green or blue one.  And does not charge at all.  Just gets warm.  

When I turn off fast charging and super fast charging, and then enable adaptive battery protection, it will sometimes charge through the night and hover at 80%.  Sometimes it charges all the way to 90%.  And sometimes when I wake up the phone is powered off but warm displaying only the grey charging circle.  

I've reset the phone.  I have tried charging in safe mode.  It won't charge when it's powered off. So... next time my phone goes down to 0%, I think that will be it!!!  

Could it be the battery?  Tips or tricks on replacing those???

Depends if your phone is old, you don't say what model device you have so you may not get a proper answer

Hey there

Are you using an original Samsung Charger and cable or a third party one?

Would suggest trying a genuine Samsung Charger and Cable to see if that solves it.

Yes and yes.  Doesn't make a difference. I've also tried charging in safe mode.

It said it was regular speed charging fine. But it should have been fast or super fast. It also said the battery was fine.
