S20 FE CPU cores usage at 98%-100%

[Leon1902]

when the device heats up check your cores usage? for me when my S20 FE, 6 cores stays at 98%-100% for no reason? can you tell me if this is the same thing for you guys?

Yes, I too have noticed that whenever my phone gets hot, the cores usage becomes very high. Another thing I have noticed is that the phone charges very slowly when it's hot. However when I connect an external mobile cooler to cool the phone, CPU usage comes down immediately and the charging speed increases significantly.

so you are saying when you cool down the phone the cores usage comes down too?
and yeah the charging speed depends on phone temperature.

[ShyamMohan01]

That's an observation, could be coincidence too. Usage does seem to come down to fluctuating between eighties to 100 for the first 6 cores. This seems odd since the processor should be throttling and reducing CPU usage when it's hot.

[Leon1902]

Yes you are right but usage shouldn't be that high when there are no background apps running except of system apps

[ShyamMohan01]

There seems to be a definite drop in usage below 40 Deg C. I think this is some kind of threshold that has been coded in. Looks like the processor makes an extra effort to reduce usage when it's above 40 deg which ends up heating the processor even more due to the extra work. Its like keeping the refrigerator door open to cool the room. Thus it ends up having to close many applications to cool the processor. Just a random hypothesis though
