1. An electronic device, comprising:
a plurality of absolute temperature sensors including a first absolute temperature sensor at a first location configured to measure a first temperature at the first location in the electronic device and a second absolute temperature sensor at a second location, different from the first location, configured to measure a second temperature at the second location in the electronic device; and
one or more processors configured for:
estimating a temperature of a user of the electronic device, using:
the first temperature measured by the first absolute temperature sensor,
the second temperature measured by the second absolute temperature sensor,
a first thermal resistance between the first location in the electronic device and the second location in the electronic device, and
a second thermal resistance between the electronic device and the user of the electronic device.
