10 tips to avoid heating on android smartphones

Over the past couple of years, there have been many complaints in new Android smartphone models for overheating – There are tons of complaints about huge number of smartphones like Lenovo K3 Note , Micromax Yureka and Yureka Plus,  Yuphoria , Spark,  Lenovo A6000 plus , Lenovo A7000, Xiaomi Mi4i , Xiaomi Mi4 and Redmi 2.

Even some of the premium smartphones like the OnePlus 2 and almost every Sony Xperia Z and also many of the smartphones powered by the ill-fated Snapdragon 810 are alleged to heat for some of the users.  The other processor Snapdragon 615 Octacore is also not optimized in some of the smartphones. In some of the smartphones it works great.

We are becoming more and more dependent on our smartphones and tablets, as they seem to become an universal device that you can use to access the information that is so important nowadays. This isn’t a bad thing, but when you depend so much on a single piece, you have to be responsible with it, to take care of it. That’s why when your Android smartphone or tablet heats up, you start to worry and ask different questions:

  • what have I done?
  • should I buy another phone?
  • does Android suck?
  • what’s causing the heating?
  • what can I do to prevent my device from heating?

The simplest explanation would be the small size and lack of ventilation. Our desktop PC’s, laptops, printers, TV’s also have heating issues but they are well ventilated, so that the plastic and the metal pieces are being cooled down. How do we use our smartphones and where do we keep them? That’s right, in our warm palms. Some of use use the tablet on solid surfaces, but that doesn’t help too much, as, obviously, it doesn’t leave space for the handset to “breathe”. The processors are getting more and more powerful with each generation and the smartphones are getting thinner.

How to Avoid the Over-Heating?

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 continue to search for the GPS signal and cause heating.

It is best to keep it switched off when you are not using the maps. Alot 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 vicinity and adds load to the processor by continue to keep the smartphone awake.

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

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 same time – Too Apps are some times open on the smartphone and can cause it to heat up due to unnecessary  processes running in the background.

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 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. Generally the news apps keep pushing a lot of notifications which I personally find annoying. If possible turn these notifications off from within the app or set it to a certain time like when you wake up in the morning or go to sleep at night. You can also block notifications right from your android settings -> apps

4). Missing Updates – When was the last time you updated your Apps and firmware/OS if you have not updating 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 smartphone 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 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 smartphones working, there is fluctuation of power from these and processor and Ram get insufficient or excess charge and times the battery drain much faster.

Always get the genuine batteries either1010 by contacting the service center 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 multi-tasking on the smartphones, usually the 2G signals are stronger and phone need 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 load on the smartphone processor and help it cool down faster.

7). Too Many Apps Installed –  More Apps you have on the smartphone 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 smartphone 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 longer duration even the best smartphones get heated up after playing graphics intensive games.

Now gaming on Android smartphone is essential for 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 smartphone 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 smartphone is continuously heating even after doing all optimizations mentioned above.

Rooting and using a custom ROM/Kernel and then under – clocking the processor is something you can try. But before doing this if your smartphone 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 center and get the device checked and ask them to replace it.  You can do a factory reset and see if the smartphone 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. You can also try undervolting but its can make your smartphone unstable so only do this if you know what you’re doing

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 your smartphone is charging; as processor will come under huge amount of stress and definitely all of the smartphone 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 tips, please share in comments and I may add it to the article.
