[br]Generally speaking, system-on-a-chips (SoCs) are extremely well optimized, and overheating is rarely an issue. They are specifically designed to handle high temperatures. When your device approaches a potentially damaging temperature, the processor speed will be reduced, making slower operating speeds one of the signs of overheating; under more severe circumstances, a warning will be displayed, preventing you from using the device until it has cooled.[br][br]If your device is experiencing frequent overheating, it could be for a number of solvable reasons, mostly related to overloading the hardware. Pushing your GPU for too long is one of the quickest ways to overheat your phone (as anyone who has [a href="https://www.androidpit.com/samsung-gear-vr-controller-review"]tried a Gear VR[/a] knows all too well).[br][br]The same can happen with demanding apps, but the burden will here fall on the CPU. Multitasking, extra features and functions, like widgets, and, for whatever reason, your phone having to check its connectivity – be it Wi-Fi, Bluetooth, whatever – all require processing power – warming the SoC – and more electricity – warming the battery.[br][br]

[br][br]Other factors that can lead to overheating are external: leaving your smartphone out in direct sunlight, for example, or throwing it into the oven. If you don’t overexert your phone and it still overheats to excess regularly, it could well be a hardware malfunction, and it would be worth trying to score a replacement.[br][br]Poor reception of internet signal also cause overheating [br]There is no better example of poorly optimized hardware leading to overheating issues than the infamous Snapdragon 810. This was the flagship processor of 2015, and was featured in nigh-on every flagship device. From the very start it was plagued with rumors of overheating issues, and, while performance varied from device to device, the chip certainly [a href="http://arstechnica.com/gadgets/2015/04/in-depth-with-the-snapdragon-810s-heat-problems/"]throttled its processing speeds heavily and frequently[/a] to avoid overheating, leading to slower performance.[br][br][br][br]
