10 Easy Ways to solve Heating Issue on Any Smartphone

There have been many complaints in new Android smartphone models for overheating – There are tons of complaints about a huge number of mobiles like Lenovo K5 Note, Moto G5, Redmi Note 4, Redmi Note 3, Redmi 4, Samsung J3, Lenovo K8 Note, Gionee A1, Honor 8 Pro, Honor 6X, Oneplus 5.

10 Easy Ways to solve Heating Issue on Any Smartphone

Even some of the premium devices like the OnePlus 2 and Sony Z4 powered by the ill-fated Snapdragon 810 are alleged to heat for some of the users – Not All.  The other processor Snapdragon 615 Octa-core is also not optimized in some of the phones. In some of the mobiles, it works great.

The above list is just indicative & not exhaustive and majority of users don’t face heating issues with these smartphones – they work great and are top selling mobiles. Heating can happen in any mobile.

It does not mean that all budget mobiles get heated there can be a small fraction of models which have some software – hardware imbalance which causes the processor to keep running at higher clock speed and hence generate more heat than the phone can dissipate.

Smartphones are becoming more of a silicon lottery – if you get a good piece it will work fine for years or you may be plain unlucky and get a defective one.  I returned a Yureka and a Lenovo A 6000 due to sound issue and heating issue in the models.  While the replacement models just worked great. 

So if one user had a bad experience with one smartphone model, to categorize that model as bad is not correct. Several other users might as well have a positive experience with the model.

Even my Samsung S7 Edge sometimes heat up while playing intensive graphics games or after watching a 30 minute You tube video.

Above mobiles are great and you should buy them for great features and specs.

Though in case you are facing heating issues with your phone while talking, charging, playing android games or browsing the internet on 3G or 4G LTE networks – here are some of the tips you can use to cool down the device.

Easy advice people give is not to play games or not to watch videos, but then what is the point of buying a mobile when you can’t do what you bought it for.

Here are 10 Easy Ways to solve Heating Issue on Any Smartphone –

1). Disable unwanted Functions like Bluetooth & Location Settings – First thing you need to do is check and disable the location tracking, in case it is own and your maps application is using it, you will observe a higher battery drain and also your phone continues to search for the GPS signal and cause heating.

It is best to keep it switched off when you are not using the maps. A lot of other apps also tend to use the location settings it is best to turn off the settings to ensure higher power saving and reduce smartphone heating.

Also, you can turn off the bluetooth if it is not being used as the bluetooth continues to search for new devices in the vicinity and adds load to the processor by continue to keep the smartphone awake.

2). Use of 4G and 3G Data for a longer duration – When 3G or 4G data is continuously used the processor and GPU are working continuously which causes heat.

The only solution here is to take frequent breaks after 20-30 minutes of gaming, will be good for your eyes as well will reduce the heating.

3). Too Many processes (Apps) running at the same time – to Apps are some times open on the mobile and can cause it to heat up due to unnecessary processes running in the background.

You can use an App like Clean master which I have found quite effective to shut down the processes and help cool down the smartphone. Clean master can remove junk files as well as free up ram by closing unused applications to cool down your phone.

If your smartphone is rooted you can use the best App known as Greenify where you can choose which processes you want to kill after you quit the application. Greenify is a great tool to manage overheating as well as improve battery life. It can close Facebook and whatsapp which tend to use a lot of Ram and at times keep the processor busy with useless work.

App Notifications – They are other culprits to excessive processor use, turn the app notifications to longer duration or just switch them off to make sure the apps are not working in the back ground. To do this open the app like Times of India and go to the settings and turn off the notifications.

4). Missing Updates – When was the last time you updated your Apps and firmware/OS if you have not updated your apps and operating system, chances are your smartphone is running un-optimized Apps and OS.

You must install the OS patches which are pushed by the mobile phone manufacturers to ensure bug fixes and keep all your apps upto date.

To do this go to play store and look for My apps and choose to update all. To check OS updates go to settings and find the About Phone tab and then system updates.

5). Old battery or Non-genuine battery – Don’t buy non-genuine batteries they can wreck havoc on your smartphone’s working, there is a fluctuation of power from these and processor and Ram get insufficient or excess charge and times the battery drains much faster.

Always get the genuine batteries either by contacting the service centre or buy it from an authorized dealer for the mobile brand.

6).  Only Enabled /WIFI / 3G/ 4G when required – This is a must for all users who are doing a lot of multitasking on the phones, usually the 2G signals are stronger and phone needs to do less work while searching for it. For extended battery life and performance keep your phone on 2G if possible.

Turn On WIFI /3G / 4G whenever required it will also reduce the load on the mobile processor and help it cool down faster.

7). Too Many Apps Installed –  More Apps you have more processes continue to run in the background – Apps like Facebook and it’s messenger continue to run background processes.

Try removing the Apps which you have not used for last 15 days. I always periodically check my mobile to remove apps which I haven’t used for many days.

Apps like Yatra or MakeMyTrip are used when you have travel needs else they can be removed and re-installed when required.

8) Long duration of Graphics intensive Gaming sessions – Try to avoid gaming for a longer duration even the best smartphones get heated up after playing graphics intensive games.

Now gaming on Android phone is essential for a lot of users, but then it is the only application which pushes your smartphone’s processor and GPU to the limit and due to which a lot of heat is generated.

If there is less space for the heat to escape due to design or provisioning of vents the mobile gets heated up. Taking a break after 20-25 minutes will make sure your mobile gets less heated.

9). Design and Processor optimization – This is the real issue with lots of smartphones and if all the above tips fail then you can try this. If your mobile is continuously heating even after doing all optimizations mentioned above.

Rooting and using a custom ROM and then under – clocking the processor is something you can try. But before doing this if your phone is new and you can return it to the seller, try to return it and ask for refund or replacement.

If the heating problem has been persistent for many days take it to the service centre and get the device checked and ask them to replace it.  You can do a factory reset and see if the phone still heats. This should be the first step to optimize the performance.

If it is out of warranty or nothing else is working, then you can root your smartphone and install a custom ROM and see if the heating was OS related issue. If it still heats you can try down clocking the processor to ensure that the boost clock is lower by 10-15% which may at least reduce the heating of the mobile.

10) Don’t Use the Smartphone when Charging – This is the cardinal rule you must follow, must not play games or use data to watch videos when it is charging; as the processor will come under a huge amount of stress and definitely the mobile will heat up due to this.

These are some of the tips that come at top of my mind to sort the heating issues with Android smartphone, if you have any other tip for the readers, please share in comments and I may add it to the article.

  1. Superb article.

    Reducing screen brightness will also work very well because screen consumes a lot of battery life and thereby battery overheats. So if reducing screen brightness to normal limits is done, it will reduce over-heating.

    Another bonus….it will also increase battery life.

  2. Some times heat is generated even while charging better switching it off while charging so less heat is generated and also the phone will get charged up fast than while keeping it on during charge and thus it will makes the phones battery last longer. My self I charged my phone while the battery at 5 percent (but kept it on) it took around 2hours but when its switched off (again the same 5 percent)the was phone was fully charged around 50 minutes its true guys just try while u r going to sleep.
