My screen lags when I put my phone on charge

[KatPet567]

Hello, I've had my S20 Ultra for 2 years now, and since I've had it, whenever I put it on super fast charge 2.0, my screen lags when I type or use it.

Is that a common occurance or is it due to my phone being refurbished before I bought it, and the workers have not done a good job at fixing it?

It sounds like the phone is overheating while fast charging and this is causing the phone to lag.

The only fix would be perhaps to not fast charge, or to not use your phone while fast charging.

It can be a common occurrence with refurbished devices or even regular devices, especially older devices as the heat sink and thermal paste on the CPU have probably long degraded.

Hope this helps!

That makes sense!! I'll just switch my charging option to normal speed charging.
Thank you lots!! I appreciate it!
