    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.

                                    How about the other end of the spectrum. Back in the day sitting outside at a cold football game I noticed that my phones animations looked really slow compared to when it's like 70° out.

                                        You mean a case will make your phone warmer, then leads to thermal throttling.

                                              Razer came out with a case with vents near the charging port to about half way up to the camera on the iPhone 11, 11 pro, and 11 pro max. And I think there is some more phones but I just can't remember at the moment

                                                    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.
