Nitro AN515-57 Do I need to apply thermal paste to CPU/replace battery or is this normal behavior?

pratikgs

I have Acer Nitro AN515-57, it has completed more than a year. I have seen some change in the temp. graph from NitroSense. It shows that when it is on AC mode (charger on) the temp get into range of 76 to 90, and in battery mode it is normal 53 to 63. (I limit my charge always to 80% & keep the charger ON while using it) Is there any problem with the battery or thermal paste? I am not able to understand. Please suggest. Thank you so much.
Please see below image. The rise is during charger connected & fall is during the charger disconnect.

Hi @pratikgs this is normal behavior because power management is different when using the battery-powered device with the charger.

When used on battery, by default, the device works at lower energy values to increase battery usage time.

When the power supply is connected, the computer uses more power from the processor and graphics.

Logically, the more energy used, the greater the increase in temperature.

All the best.
