Sensorly runs when my phone is plugged in and I won't let it use more than 10% of my battery when not, and both ways my phone runs at around 105°-115°. GPS when plugged in shoots my temp up to 120° when unplugged and up to 125° at the extreme when plugged in. Sensorly, GPS, and trying to maintain my battery while plugged in made my phone jump to 130.2° last Friday in Washington. Let the egg fry begin!
