A hot smartphone does not necessarily mean that it is overheating or that something dangerous is happening. Read in this article what is happening and what to watch out for.
A hot smartphone should not always worry you. Up to a certain point the heat is perfectly normal. After all, today's phones automatically adjust their internal temperature when needed. However, there are steps you can take to improve their energy efficiency.
What happens and your phone heats up
Your phone is an electronic device, so the movement of electricity needed to operate generates heat. But if your phone regularly overheats to the point where it is inconvenient to hold it in your hand, there could be a more serious problem.
There are only two parts in a mobile device that in normal use can make it warm. THE battery and system on a chip or otherwise SoC. When you feel the heat on the back of the device, it usually happens because the metal casing inside the phone tries to transfer heat to lower the internal temperature.
The chips in today's smartphones are more efficient than those of previous models, and without a doubt, the same will be said for future devices. Due to this increased efficiency, you will still notice heat in your hand at certain times.
Why is your phone hot?
Your device will raise the temperature in cases such as:
- Using an application with a high demand on the processor, such as one video editor or music.
- Flow content. Watching YouTube or Netflix for hours makes excessive use of your phone's processor
- When running an update to your system software.
- Recover files from backup.
- Intensive game that relies heavily on content download.
- Phone settings with excessive power requirement. Full screen brightness with animated wallpaper and many widgets.
- Do not update your applications. If an application fails it may cause overheating. Updating your applications and operating system is important because Updates often include bug fixes.
- Infected phone. You have a virus or an application does mining for bitcoin.
- Charge your phone while using it.
Once you stop performing any of these tasks, your phone temperature will return to normal.
There are external factors that can also make your smartphone warm. These can be:
- If you leave your device in a hot car.
- Sit outside in direct sunlight for a long time.
- A combination of using a high-demand processor application (such as GPS) in a hot environment (such as a car).
Your phone is designed to operate within a normal operating temperature range. When the indoor temperature is above this range, the phone will try to adjust its temperature by performing various short-term tasks, which may include:
- Screen reduction
- Temporarily slowing down or stopping charging
- Turn off the camera flash
- Slow down performance levels for high-processing or augmented reality applications or functions.
- Weakness of the cellular signal
When your device overheats, it will display some warning messages on the screen.
On iPhones, for example, when using the navigation system, it says: "Temperature: iPhone needs to cool down". During this period, navigation is limited to audio navigation instructions. In another case, the iPhone states: "Temperature: iPhone must cool down before you can use it", and the use of the phone is limited to making emergency calls.
In this case, the best thing to do is turn off your phone and move it to a cooler location. Once cool, restart it.
Hot or hot? What is the limit?
And when is a phone called too hot? In general, the internal temperature of a telephone can reach 37 to 43 degrees Celsius and is still considered normal. If you want to know the internal temperature of your phone there are some free apps that tell you.
If you are using an Android phone, you can install it AIDA64 , or the CPU-Z, which will give you a lot of information about your device hardware and software, including a phone temperature report. Similarly, Apple has expanded the information you can see in the "Battery Health" menu to the latest iOS 12.3 update, but this does not include a temperature display.
However, since we have already found that some heating of the phone is normal, it is better to determine the overheating based on how often you notice that your phone is warming up or if its temperature is naturally unpleasant. Your phone should not heat up several times a day or for seemingly unreasonable reasons.
Those of you who have an iPhone, according to Apple, iOS devices work best when the ambient temperature is between 0º and 35ºC. When storing your device, only a temperature between -20º and 45ºC is recommended.
How to cool your phone immediately
For a quick fix, try removing your phone case first. While the case itself should not overheat your phone, it may trap heat. Removing it can lower the temperature of your phone faster.
Then turn on airplane mode to turn off the causes of battery drain, such as wireless radio, Bluetooth and Wi-Fi, or cell phone signal search. This is not the most practical option, but it can be a quick way to cool your phone in case of overheating.
Put it in a shady place, with the lowest possible natural outside temperature. Do not put it in the fridge !!! You will destroy it.
If it is still too hot, just turn it off completely.
Troubleshooting and what you can do
There are many precautionary steps you can take to ensure that your phone does not overheat. Most include regular maintenance on your device.
1. Pay attention to the outside temperature
Do not store your device in extremely cold or hot conditions. For example, do not leave the phone in your car during a hot summer day. Direct sunlight should also be avoided. Watch out for windows where when the sun goes down it can affect it.
2. Do not do more than you should
Do not do simultaneous tasks or continuous for a long time. Doing anything on your device for a long time will warm it up and sometimes you will need to take a break to cool down. This does not mean that you can not watch your favorite movie on steaming or stop browsing the web after a few minutes. However, be aware that continued use of anything can eventually cause a short-term heating problem.
Examples of when they could warm up your phone are:
- Excessive use of Bluetooth or Wi-Fi
- Continuous shooting of photos or videos
- Game for hours
- Stream each episode of an entire series, without a break
- Automatic brightness function
- Run multiple applications simultaneously
3. Restart your phone.
Occasionally restarting your phone can help prevent overheating. due to minor software problems.
4. Malware and antivirus
Although rare, your smartphone may overheat due to malware. In this case, you should soon run a malware scan and fix the problem. There are various malware related products on the market, including Avast Security & Privacy , Avira Mobile Security, ESET, Lookout, etc.
Ask for help
If you are still convinced that there is a problem with your device, seek professional help from the manufacturer of your phone.
These people can look at your phone (even remotely) and determine very quickly if there is a problem. Before contacting support, make sure you have followed the troubleshooting steps above. The manufacturer may ask you what steps you took before contacting technical support.
