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.

  • Just in case you were wondering why motorcycle clothes are made of leather - It's to offer a level of waterproofing and abrasion resistance should you fall off and slide across a road. It won't protect you from longer slide but unlike many other synthetic materials it won't melt and stick to your skin as a result of the friction, road rash sucks enough as it is without the doctor needing to cut melted crap away from what would have been otherwise healthy tissue.

  • Well my case basically lets me charge to 200% so I don’t really care. By like 3PM I use up the extra battery. I have a problem...

  • Linus, I've noticed on the Raspberry PI 3 that it runs cooler upside down. I'd be interested to see if running these tests with the phone upside down would make it throttle more. However, phones aren't usually used that way so...

  • What I learned aside from cases not really affecting phone performance is that phones are filthy little cheaters that will let your phone heat up while running known performance testing apps so the score looks better.

  • Question for those who understand this better - wouldn't the fact that those phones are IP68 or something and have a backplate made of glass, a very bad thermal conductor, render whatever you put on the back of a phone pretty inconsequential? I mean, unless it's something active - either heating or cooling things a ton by itself, like an open flame or... dry ice. One way or another, very hard for regular smartphone users to even get to the point of thermal throttling phones anyways... I use one of those wallet cases. Been using them since the first phone, and on the current already ancient OnePlus 3 I started using it a couple of months before getting it. Zero problems. Well, I never even got to make this phone uncomfortably hot yet, despite playing some simple games and watching a whole ton of videos on it.

  • A thin plastic or silicone shell around a phone will prevent it from heating up too quickly on the dash of your car in its mount. I just got a new Galaxy S10e and an LG G8, and they both overheated within seconds of being placed on my dash. With the case? Not at all.

  • Linus, this was a great test, but I think an additional test with the phone facing screen down to the desk would have better results. If you think how most phones are made, the cpu is normally on the top side of the motherboard for instance iPhones have the cpu chip facing upwards towards the screen just above the sim card tray, so that could explain why the XR pushes heat towards the screen and as we all know heat rises so that probably factors in. if it was facing towards the desk not only is the desk insulating the screen further but the heat naturally will have to go up towards the back of the phone. This is just I thought of mine after watching your video but it seems logical from my point of view, I could be entirely wrong.

  • Dude, why are you surprised about the case being overpriced? It's an Apple product! You could've the gotten same exact or similar leather case but without the Apple logo for much cheaper!

  • Great info. Well done.

  • Please do 2 .0 of it doing a test by testing apps gamesmanually to make the phone throttle please also do by applying a tempered glass over the phones

  • Use a magnetic case it affects to much

  • Back when I had my S4 I noticed that the Otterbox case I had on it would cause it to start overheating. I removed the Otterbox case and kept it bare, and it stopped a lot of the stutter and heat from getting trapped.

  • Do Plastic Vs Glass screen protectors + case and You need to factor in holding the phone whit no case as the Human body dose act as a heatsink. And you also should use other phones from lower tiers as not all phones have as good thermal management as the top tier ones also phones whit plastic , glass and metal backs should factor in . not saying yo should do all in a single video but it would be very interesting to see the comparison and results

  • I tear these apart everyday almost.. The reason it relies mostly on the front for cooling is because of how it's designed and the battery location. If you ever tear apart a LG, Samsung, Motorola -- you'll notice all the heat plates are on the screen-side of the board, with usually a thin film of copper between them and the actual LCD. The back gets hot all on it's own from that battery usually. At least in my experience.

  • So then what about if you use a case AND a screen protector? Does having an extra layer of tempered glass on top of your screen make it thermal throttle worse?? Or does using a plastic screen protector make it thermal throttle worse??

  • So a battery case with additional exhaust fan at the bottom vent is the answer ? Also if phones radiate heat through the screen what does a screen protector do to that process ?
