Running MetMask browser with less than 20 tabs is causing the iPhone to warm up to a degree the back of the iPhone is almost hot to the touch. As an Apple Senior Support Advisor I can say no application is supposed to utilize more than 29% power consumption in a 24hr period or more. This was the only place I could find relevant to post this kind of issue. Protocol at Apple dictates to delete from App Switcher and/or delete app and reinstall as well as make sure device is up to date and app is up to date.
turned off device and turned back on >> issue persists
removed from App Switcher >> issue persists
device is up to date
I will report back changes made and outcome.
