Why SmartPhones Overheat ? 6 Common Reasons Explained

Do you find that your phone gets too hot to handle when you’re using it? While it’s natural for smartphones to create heat and get Overheat, especially when used often, excessive heat can indicate internal damage, software problems, or even malware. We’ve outlined six common causes of mobile phone overheating in this post.

The Most Common Causes of Mobile Phone Overheating

1. Excessive smartphone use might cause a phone to overheat.

The principles of physics are unbeatable! Using the phone’s camera for extended periods of time, using the phone with a high screen brightness, or playing graphically intense games are all major reasons of overheating. If you use your phone frequently or nonstop, its processor will have to work continually, which will generate a lot of heat. Similarly, using the phone’s camera for an extended period of time causes the camera, CPU, and screen to work continuously, generating heat. The heat is dispersed via the phone’s body. As a result, demanding apps like games can frequently result in a toasty warm phone.

In a word, anything that uses a lot of processing power will certainly cause your phone to heat up. But demanding apps aren’t the only ones to blame. Sub-optimal settings can also result in excessive heat generation. The screen brightness has already been mentioned. That’s one of the most common causes of overheating when it comes to sub-optimal phone settings. Aside from that, poor cellular network conditions compel the phone to look for signals continually, causing it to overwork and generate a lot of heat.

2. Malware or a buggy software update can cause your phone to overheat.

Unfortunately, faulty software is frequently the root of mobile phone overheating. A problem may cause the programme to become stuck in a loop, using processing resources, while other bugs may cause excessive memory consumption, resulting in increased heat generation – you’ll notice that your phone becomes hot and the battery drains at the same time.

One ‘new’ wave of malware that has recently been in the press does not actually steal data. Instead, it consumes resources like your processor and battery life! We’re talking about covert Bitcoin (or other cryptocurrency) mining software that consume a lot of computing power to mine cryptocurrency in surreptitiously. Although Android phones are more vulnerable to malware than iPhones, it’s still a good idea to be safe even if you have an iOS device. In any case, only download apps from legitimate app shops.

3. A faulty battery, cable, or charger might cause a mobile phone to overheat.

This is more harmful than you would realise. Damaged or illegally obtained batteries, cords, and chargers can cause mobile phones to overheat to the point of being unsafe. Because not all chargers are created equal, they have the potential to overheat cellphones.

Meanwhile, physical damage to batteries can make them unable to resist the rigours of charging or even moderate usage, which is why we frequently hear reports of phones exploding while charging. The majority of these instances involve the use of unauthorised chargers and low-quality cords. Original or approved third-party accessories should be used.

We also advise against charging your phone while sleeping because you may not be able to identify major overheating issues. Most essential, do not charge your phone when it is under your pillow. Because the phone is covered by the pillow, heat is generated that cannot be dissipated, and the cushion can catch fire.

4. Blocked ventilation might lead to overheating in some cases.

Mobile phones are designed to resist the stresses of everyday life. When the charging port is obstructed, however, the device overheats. This isn’t an issue for most new phones (high-end cooling systems have become prevalent), but it could be for older models.

This is especially likely when the ambient temperature is high, such as on hot summer days, or if your phone has been left on the dashboard for an extended period of time, exposing it to direct sunlight and severe heat. The heat generated by the phone’s GPS, processor, and screen adds up. This could cause the phone to overheat, especially in hotter climates like India. We recommend that you don’t leave your phone in direct sunlight because it not only generates more heat, but it can also damage the phone’s body and display.

Low-quality phone cases are another cause of overheating mobile phones. They not only protect your phone from drops, but they also keep it cool. The rear of many phones is used to disperse heat away from inside components like processors. You’re preventing this heat from being adequately dissipated into the air by putting a thick case over the phone. As a result, you should avoid overly bulky phone cases, especially those with poor thermal design.

5. Internal Damage Could Cause Your Phone To Overheat

Damaged batteries, as previously established, are a major cause of overheating phones. This can also be caused by other types of internal damage, including age-related damage. The thermal paste between the processor and the heat sink, for example, may start to flake off, limiting the heat sink’s efficacy by preventing it from transferring excessive heat away from the processor.

Some phones have sophisticated cooling systems. These may be destroyed if you drop your phone and cannot see the damage, but you may notice that your phone is heating up faster than usual. Impact damage can loosen components and cause short circuits, some of which may allow your phone to function but at the expense of excessive heating.

Because the manufacturer’s normal warranty does not cover accidental damage, you should consider purchasing an accidental damage cover plan from the brand or a third party. The Spills & Drops Protection Plan from Onsitego covers all types of physical damage, including those caused by water or a fall. We offer a “No Questions Asked” policy, which means you won’t have to explain anything while we fix your broken phone.

6. Older hardware has a tendency to overheat.

Due to a variety of circumstances, older technology, particularly processors, can frequently overheat the phone. The thermal paste of the phone can wear off over time, leaving the processor vulnerable to poor cooling, as mentioned above. However, you may always take safeguards by adjusting your usage habits (taking breaks when playing the latest, most demanding games) and changing settings (turning off superfluous functions like as Bluetooth or Wi-Fi, or limiting the display timeout).

How Do I Cool Down My Overheating Phone?

  • Below are some fast fixes for overheating concerns on your mobile phone.
  • When playing games, take frequent pauses. Your phone will be able to cool down as a result.
  • In regions where there is no signal, turn off Wi-Fi or mobile data. If your phone is continually looking for a signal to connect to, heat will build up faster.
  • Install programmes only from reputable developers, and only from the official play/app stores. This should keep you malware-free.
  • Regularly update your apps because new versions may fix flaws that cause excessive power drain and heating.
  • A phone with a damaged battery should never be used. Avoid using grey market cords or chargers and have the battery changed by an authorised service centre.
  • Do not leave your phone in the car. If you must, keep it in the glovebox and out of direct sunlight.
  • Maintain the cleanliness of your mobile phone. Wipe away any dust, and make sure the charging ports and speaker grilles are clean.
  • Avoid cases that are too large. You don’t get much protection, and these act as insulators by preventing the phone from dissipating heat.
