Xperia 10 III temperature throttling

My Xperia 10 III seems to be very sensitive to throttling at higher temperatures. During normal use, it’s not that noticeable, as it usually takes about 30 minutes of constant use before you notice any slowness. But sometimes it’s enough to keep the phone in your pocket, and just the heat from your body will heat the phone enough for it to start throttling immediately when picked up. Charging the phone using slow charging is also fine, but when using Quick charge (20 W), it doesn’t take more than 5-10 minutes of charging to heat the phone up enough for the thermal throttling to kick in.

Below is a video demonstrating this behavior while charging:

Is this behavior normal for the Xperia 10 III, or is only my unit affected?

Same after quick charge with battery between 40 °C and 41°C,
I’m not affected, I don’t think it’s normal behaviour.
