I haven´t noticed that at all. Regardless of whether I´m charging it or just holding it.

Let me measure it with a infrared temp gun.

My device showed 79.7°F/ 25.9°C at its hottest point, not charging a few minutes ago. All antennas on, bluetooth and wifi connections active, processor working at 5/6 points. Screen at 1st setting. Pretty heavy loading on the device.

After about 5 minutes of charging the hottest point shows 79.6°F/26.2°C. Still doing all the same tasks as above.

For comparison ambient temperature is 75.0°F/23.9°C and my hands measure around 78.1-78.4°F/25.6-25.8°C. I´d say it´s a pretty cool device.

Also, my Dell laptop measures 92.8°F/33.8°C where it is warmest on its underside. That always feels burning warm to touch when I place it on the belly.
