Reasons for Smartphones overheat, and Ways to Stop it


Smartphones will heat up from the moment you switch them on; this is unavoidable and generally protected. In any case, phone overheating can be a major issue, harming gadgets and influencing performance. In this article, we address 3 important inquiries: what causes a smartphone to warmth up, what makes it overheat, and how can it be avoided?


For what reason do smartphones heat up?

The appropriate response lies in an essential property of physics: movement produces heat. Our smartphones have to physically move things around to work by any means, so they need to produce heat. The amount of heat your smartphone generates is to a great extent proportional to the amount of electricity moving through it. If you’re playing a game that requests a lot from your focal and graphics processing units, both housed in a central framework on-a-chip (SoC), they will turn out to be warm, as they require more power to do their tasks.

Your phone ending up warm is no reason to stress, they’re intended to work that way, yet if it turns out to be horrendously hot, you likely have cause for concern.

For what reason do smartphones overheat?

Generally speaking, SoCs are incredibly very much optimized and overheating once in a while an issue. They are explicitly intended to deal with high temperatures. At the point When your device approaches a possibly harming temperature, the processor speed will be decreased, making slower operating speeds one of the indications of overheating; under progressively serious conditions, a warning will be displayed, keeping you from using the device until it has cooled. If your gadget is encountering regular overheating, it could be for various feasible reasons, mostly related to overloading the hardware. Pushing your GPU fora really long time is one of the fastest approaches to overheat your phone.

While there are security checks in place, and most phones don’t experience from frequent overheating, when it happens normally or to extremes, the heat can damage your gadget.

What damage can be done?


Inside modern smartphones, you will discover a lithium-ion battery. These are clever traps of technology. A non-rechargeable battery takes into consideration a chemical reaction, designed to generate electricity, to occur in one direction: electrons leave the battery to travel through a circuit (your phone). Rechargeable batteries enable this reaction to go two different ways, so the battery can give and take charge, and do it multiple times.


Lithium-ion batteries are the best rechargeable batteries accessible right now, however, they still have inconveniences. There are two main problems:

  • One is that they degrade, notwithstanding when they’re not used. This happens generally slowly, yet you’re still lucky to drag two or three years of use out of one.
  • Secondly, they are very touchy to heat. Anything over about 30 degrees centigrade is going to begin negatively impacting a lithium-ion battery, and this is a temperature it likely climbs above every time you charge it.



When it comes to the SoC, the processor speed will be throttled to anticipate overheating, which slows your gadget down, sometimes to the point of unusability. If there is an excess of warmth for too long, it can damage the chip physically.

Again, similarly as with the battery, this last possibility is probably not going to happen, as there are security measures in place. But even so, it can be concern feel over the top heat and irritating to need to trust that your gadget to cool down. A few gadgets are prone to overheating (Sony Xperia Z3+, I’m looking at you), however, it is unusual, otherwise.

Ways to avoid overheating

Battery tips

Pretty the most exceedingly terrible thing you can do to a battery is to expose it to heat when it is completely charged, so getting it to 100% is an awful thing, as your battery will be occasionally checked and charged back up to 100%, applying stress.

The profundity of release additionally affects battery life, meaning it’s best not to give the charge run down to zero percent. If you charge from, say, 30% up to around 80%, you’re treating your battery pleasantly and doing a good job of avoiding cell phone overheating. In spite of the fact that it may sound like a torment (it is), it could more than double the number of charge cycles you get out of a battery.

Power saving

To manage or anticipate overheating of the SoC, guarantee you don’t play demanding games or watch videos for too long, don’t perform various tasks on applications that require a great deal of preparing power, try to avoid using Bluetooth for prolonged periods, and only use Wi-Fi if its stable. Generally, stay away from however many demanding processes as possible.

Get naked

Actually no, not you. Not necessarily, at any rate. When it comes to smartphones, a case or cover can trap heat produced from the handset, so if you need the gadget to cool off a bit, strip it and expose the body to the air.

Use an app to save power

There are apps accessible on the Play Store that help to deal with your phone’s procedures with an eye to conserving power and resources. You can use them and save the power of your smartphone.

Price: Free

Don’t sweat it

Don’t overexert your phone or leave it in direct sunlight in mid-August, and you should most part be fine. Most modern smartphones are intended to deal with all yet the most strenuous activities, and the chances of a catastrophic meltdown are minuscule.
