How to find the current temperature of an iPhone's CPU? There are extremely useful utilities like iStats for viewing the CPU temperature on a device running macOS.
Is there a way to view the current CPU temperature of an iPhone?
Note: the reason I want this info is because an app I regularly use runs some very heavy processes which heat up the phone to very hot temperatures in around 15 minutes. I would like to be able to take the phone's temperature before and after 15 minutes of using that app.
There's a lot of temperature information in sysdiagnose in iOS, might be a good place to start.
