![]() ![]() Granted, most flagships will still handle the games you throw at them, but they will either not be quite as smooth as the dedicated gaming phones or lose some quality. While benchmarks would let you believe that all current flagship phones perform more or less the same, things quickly change with longer loads. Max surface temperatureĬolor us surprised! While gaming phones outdoing mainstream flagships was hardly shocking given how tightly the latter are packed, we never expected the differences to be this big. ![]() While the fan only marginally improved overall performance levels it did wonders for its surface temperature and comfortable handling. The ZTE nubia Red Magic 3 and its active cooling fan are the definate champs here. Sadly we alreadly learned that this comes at the expense of performance, so it's not really a great trade-off. The Pocophone F1 and Huawei P30 Pro maintained the lowest and most comfortable surface temperatures of the bunch. The Samsung Galaxy S10e got surprisingly toasty all around, but not nearly on the level of the Black Shark 2. The latter has its hottest point in a rather odd spot on the top bezel, though. It's the exact same thing with the Xperia 1 and pretty much the Mi 9T as well. The rest of the phone remained perfectly fine to hold. Event though in absolute values it got as hot as the Black Shark 2, it was only that one spot, which almost never gets in contact with your hands. It is really, really uncomfortable to hold while in this state.īy contrast, most other phones tend to have one single, relatively small spot with a peak temperature. The Chinese manufacturer uses the mostly metal outer shell of the phone as a huge heatsink, meaning that the phone heats up pretty much all around to a hand-burning 47 degrees. The definite stand-out in this department is the Xiaomi Black Shark 2. The only slight issue with this tactic being the abundance of nerve endings in said hands that don't feel particularly comfortable when exposed to heat. Your hands actually make a pretty good radiator as well. ![]() Surface temperature and comfortĪfter all taking the heat away from the chipset normally means it's transferred to the body of phone. After all just hand comfort can be an issue with prolonged gaming sessions and it's important to see how the different smartphones manage that. One final thing we wanted to examine before we wrap this up was surface temperature. GFX 3.1 Car scene (1080p offscreen) Phone The worst offender was last year's Pocophone F1, which lost nearly half of its performance once things started heating up. Meanwhile, those around them would see significant drops in their GPU perofmance, which would inevitably result in either dropped frames or decreased graphics quality. ![]() The Black Shark 2 and the nubia Red Magic 3 were the only phones that retained their performance after an hour of stress testing. This turned out to be the most major win for the gaming phones yet. This way we can see how the different chipsets and phones react to overheating from a GPU standpoint, even if the GPU is not the one necessarily putting out all the heat. So, as a compromise and a showcase of how much gaming performance you will be losing we ran the GFX Bench 3.1 Car test twice - once when the chipset was cold and again when it had reached its thermal threshold. The info is scarce and often logged in vastly different folders if at all so no easy, reliable and convenient graphs were available here. Unfortunately Android and most smartphone manufacturers are not particularly cooperative when it comes to letting you monitor GPU stats. That would mean performance and thermals all plotted out on a graph over time. To be as thorough and precise as possible we really wanted to monitor GPU activity in the very same manner we did for CPU. After all, we are discussing extreme and prolonged loads here so realistically gaming and sustained performance are the actual subject of this examination. Now that we've investigated the CPU thermal-throttling situation it's time to talk about GPUs. ![]()
