So, to save you the trouble of checking which phones heat up and which phones don't, we put six of the most popular smartphones out there to the Ultimate Smartphone Heating Test. We're demonstrating this video using the iPhone X, Pixel 2 XL, OnePlus 5T, Galaxy S9 Plus, Mi Mix 2, and the Redmi Note 5 Pro to check how much they heat under different situations from calling to charging and video recording.
