Which phone is hotter? Xiaomi Mi4 vs Meizu MX4 Pro vs Honor 6+ heating test

Which phone is hotter? Xiaomi Mi4 vs Meizu MX4 Pro vs Honor 6+ heating test
Thermal imaging at its finest, folks, we can't imagine a better use of it than measuring how much our smartphones heat under gaming pressure, and here it is, a heating comparison between the three hottest handsets from the most up and coming Chinese manufacturers.

The recently released Meizu MX4 Pro flagship has been put to the test together with Huawei's dual camera Honor 6 Plus, and Xiaomi's ever-popular kid the Mi4. Now, this test is very interesting not only because we don't see thermal imaging comparisons every day, but also because the three handsets run three totally different chipsets that are representatives of the three largest brands in mobile silicon at the moment.

Meizu MX4 Pro is powered by an octa-core Samsung Exynos 5430, clocked at 2 GHz, Huawei uses its own octa-core Kirin 925 silicon for the Honor 6 Plus, clocked at 1.8 GHz maximums, while Xiaomi goes with a more orthodox Snapdragon 801 chipset, whose four cores are clocked much higher than the other two, at 2.5 GHz maximums. 

What numbers did these chipsets return? You can see them in the slideshow below, but long story short, the lower clock speeds of Huawei's Krin processor, coupled with its heat-dissipating body, were keeping it way cooler than the other two powerhouses, whose backs were getting quite... toasty, especially the Mi4. Check the heat maps out.

Go figure which one can cook bacon! 810 should be able to cook a turkey.

A9X should be able to cook a sheep X1 should be able to cook a cow i7 should be able to cook a herd of cows R9 390 should be able to cook a town Nothing surprising here

Oldest brand wins, xiaomi shows they lack quality :)

Huawei own processor are better than overated Qualcomm

Aaand that Mi4 is powered by SD801. So Huawei is better than Xiaomi.

I guess Qualcomm is overrated for him just because it's American.

huawei's own processor is not better than snapdragan at all. QC is not over rated... I own mediapad x1 and note 4 at a time... although huawei has great devices but cant match the performace and experience of note 4... infact, I think no other phone can match the experience of note 4

i don't think so especially compare both smartphone with its price. then for a 380 euro meizu mx4 pro can kill note 4 all.

Xiaomi's Redmi 1s is hot too.

So is the Sony Xperia Z3... cooks in my hands doing simple tasks and playing basic games

That just says there something (app) in the background using your phone without you knowing. My Z1 never gets hot doing simple task. Proud to say Sony has been using the liquid heat-pipe cooling technology since Z2.

So 801 is hottest of the three, kirin is the weakest, but doesn't hot too much. If 801 can get hot like that, how about the 810?

Depends how you like your balls cooked. Just forget about having a baby for a while if you have a smartphone with SD810.

925 is esentially same as exynos 5420, and exynos 5430 is 20nm dieshrunk of 5420..... It's strange it runs so much hotter.

It's running a QHD display.

I think the choice of material for the phone affects these heat comparison

It's physics, not your thought...

No, he's right. I don't know what each of these phones exteriors are made from, but that material will affect these images. Aluminum will transmit more heat than plastic. The thickness will also affect the results. Plus, whatever kind of internal insulation there is, if any.

Snapdragon seems to be hotter but it eventually crashes the competitors in performances -http://www.futuremark.com/hardware/mobile S805 - 23217 +68,04% E5430 - 17943 +29,87% Kirin 925 - 13816 +0% HiSilicon Soc is garbage compared with Snapdragon, Tegra, Apple Ax

13. TyrionLannister unregistered

None of these phones use SD 805. It's irrelevant here:

Take even the S801, it's still over the Exynos and the Kirin S801 - 19764 +43,05%

15. TyrionLannister unregistered

In GFXBench though, 5430 beats S801. Also 5430 has a better CPU. Anyway, I agree that the GPU in kirin is crap.

Exynos uses cheats to boost its GFXBench score, something that cannot be done with 3DMark. Same thing to all the CPU scores... The raw power is needed in games, having a 10% powerful (with cheats) CPU is useless, only the GPU matters, and in 3D Mark the K1 and the S805 are the winners. Mali-T628 MP6 cannot compare with Adreno 330 or 420.

It's higher LOL. correct your vision.

Have a link to prove Samsung cheats after 4.4. Even anandtech says Samsung didn't cheat. Same result from GSMArena. You can live in your dream world.

Not cheating but smart processing. It uses the reserve power when its needed. Its all programmed.

try lumia 930 they go beyond 50C

If it heats up, they should use heat sinks Finns or have air hole vents for heat to escape. Stupid dum OEMS. Or lay an carbon fibre where the CPU, GPU are.

Krait architecture is 3 years old and originally designed to run dual core at 1.5ghz. Of course heat is a huge issue. Adding cores and clock speed always will create that issue with limited heat dissipation. Any heat is wasted juice out of your battery. So CPU Temp (instead of body temp) is most important because it dictates throttling behavior (which reduces performance to reduce heat). Sometimes high skin temp means good thermal performance, like in Metal devices. Plastic insulates the heat leading to faster throttling.
