@@habibhussain1808 i have the iphone x and it's almost ALWAYS hot when i watch some 4k videos or play some games...... like holy shit it's even without a case
My hypothesis The skin makes the phone slightly hotter because vinyl has a lower thermal conductivity (about 20% lower) than air. The TPU case does not make much difference in temps because TPU has a similar thermal conductivity to air. The enclosure makes the phone slightly cooler because of the large metal contacting the table to act similarly to a heatsink. It would be interesting to see this experiment repeated on a different surface or with the phone suspended.
There might be some cpu throttling involved as well, which will prevent the phone from getting too hot. It would be quite interesting to see how a case affects cpu performance over time...
One thing there: On the full enclosure style case, you specifically tested a Love Mei. They're the most expensive for a reason, haha. It's built as a heat sink. All that external exposed aluminum is specifically designed to cool the phone. Personal experience there in the past with an LG G4 - an Otterbox case would overheat it to the point of critical cooldown mode if I tried to use it while charging, whereas the Love Mei case I replaced it with later merely got a bit warm in my hand. Now one thing specific to the LG G4 is that the back case cover is not plastic, but rather aluminum, to serve as a heat dissipation area. You even showed that on your FLIR shot, as the heat sink aluminum part was hotter, because it was doing it's job. So... I'd not rule out the fully enclosed cases from being warmer just yet, simply because you bought a really good one, rather than the more commonly purchased all-plastic-and-rubber ones, such as the very popular Otterbox cases. (Man I miss the old fully waterproof ones they made, haha.)
Great finding! I always remove the case of my phone everytime I charge it. It's the clear plastic case kind. I don't know, I'm just paranoid over phones heating up with a case during charging
Quite an interesting finding. Sometimes when using my phone while charging and felt it get warmer, I've removed the case to aide with cooling. I guess maybe it wasn't really all that necessary. Or like I've seen in lots of phones torn down by JerryRigEverything, the heatsink is facing the display instead so the rear doesn't matter all that much.
I actually really appreciate this video. I don't there's a test just like this out there. I was always wondering how cases effect my phone heating up especially now that I have a phone that runs QHD and 90hz
Try cases with WiFi speed, since manufactures have gone from plastic backs to glass backs to improve WiFi speed and most of us decide to put a case on our phones anyway. I would love this video idea, I always thought my phone gets hotter because of the case.
The enclosure has a piece of plastic that may have a lower temp on the outside than the true screen temp, but the case feeling hot is a really GOOD sign that it's helping because that means the heat is getting out to where you can feel it. Definitely not what I expected. All case makers should be testing this and routing this benefit if it exists for their design.
That Samsung Galaxy S10 is just so beautiful especially that prism white colour. Can't wait to switch to the S10 from my iphone 7 plus. This was a HOT test. 🥵🥵 Oh ok I will leave now....
It's likely that the battery controller is limiting the charging current to prevent overtemp. So regardless of how insulated the phone is, the temperature won't rise; the charging time will just suffer slightly. An additional test using a known insulator (eg. foamboard, wool) would establish whether or not this is the case. In general, it's good practice to validate your results with both positive and negative controls.
Slim Metal cases will interfere the signal strength. Plastic, if not negligible, won't do that much of a difference. But thick plastic case with back metal plate is the literall worst, my phone signal dropped at least 2 bars
Arun, air is an insulator. Almost every denser material will allow heat to spread. So an air layer will work as an insulator, not a help to get rid of. For this case, you need an air flow. The more dense and cold mass you pack next to your phone, the less your phone will heat up. In case this mass is pre heated by sun or simply wearing in in your pocket, the harder it is for the heat to "creap into" the mass.
Great video and I was waiting for it since you did the overheating comparison. Something to note that when the phone is held in your hand this would help to dissipate the heat even more
For case I choose middle thick and black color. Middle thick to keep balancing heat and protection and black color to release the heat to case quicker.
This IS good news Arun 😃. I have had a fairly substantial case on my Phone for 4½ years, (I actually "almost" forget what my Phone looks like, sans the case - a Nexus 6P), and although I have heard much Ado about Phones getting Hot, I have to say I've Never experienced that with mine 🙂.

Don't phones throttle performance especially under heavy load like this situation. And wouldn't it then throttle down to the same upper limit temp? Seems like you should get better performance from any cooling effect provided rather than actual better temps because of the adaptive cpu voltage. Better cooling would allow the phone to up the cpu voltage and increase performance but that would bring the temp back up. Is there a chance the thickness of the cases is preventing an accurate internal thermal measurement or is that not how it works? Could there be something else at work here?
when im playing genshin impact on my sd870 phone and it gets much more hotter when it has a case than nothing. and phone cooling fan works much better without a case. you can use cpu z to check
The double stress test is just pushing the phone to the control limits. The CPU is throttled based on temperature, the charge rate is manipulated to keep temperatures under control. That's why there's not a big difference.
This was an awesome test and I really appreciate you doing the work and effort to answer this question that many of us had because I had sworn that my TPU fit case from 21 tech what's causing my phone to run a lot hotter than it would without
Aaron -- I've always wondered why someone hasn't created a case that has a grid of tiny holes on the back for ventilation? I get some want water protection, but personally I just want drop protection and additional ventilation only make sense to me.
Putting a phone flat on the surface is one way to go, but i am sure the results will vary if u hold it up for example. Usually phone heats up while gaming and it matters a lot, because thermal throttling to me is a big issue.
i personally am running the samsung galaxy s9 with the samsung led case, but because i am rarely doing anything taxing on my phone, i have no games installed and the most tasking thing i do to it is either charging it or updating apps. this results in the phone rarely even feeling slightly hot and my end of a normal day battery level is usually around 40% but when i'm not working and listening to musik most of the day does the end of the day battery level rise to 75% from a full charge in the morning. but when i do something taxing is it always on my computer and not on my phone so it is spared from some of the hardest tasks which i would imagine would increase the life of the phone.

this is my thinking, the phone will keep the TEMP at a 45 so the difference might be not in the temp but in Performance.

You should have included a flip cover or a leather case as well. They are pretty common.
Agreed completely
You should measure throttling as the phone could be cutting back performance to keep the temprature down

Quite possible that the phone is thermal throttling to keep it at a comfortable holding temperature.
