    We test an iPhone Xs Max and a Samsung Galaxy S10+ with a variety of phone cases – including the Apple leather case – to see if a case can make your phone slower by affecting its thermal performance.

      you should have placed the phone on the same surface and not move it or take it in to your hand. the higher test result around 4:55 was just after the phone was placed on the counter witch draws heat away from the phone better than air. at least for a short time.

                            Screen + max brightnes = heat traping all ways of heat exiting the phone = performance drops

                                You could also test phones signals, if it gets affected.

                                              Great video. Next test, screen protectors (the plastic ones and the tempered glass ones).

                                                  Run on the iPhones the game GRID Autosport at the 60 FPS Setting with max brightness. It starts to fucking die after 5 minutes of gaming. It auto dims the screen and framerates start to go below 20 FPS.

You said something very interesting here about apple using their screen as a sort of cooling system. What about glass screen protectors. Would this cause more throttling?

                                                                              Forever a fan of your knowledge.
