Solving the Mobile OverHeating Mystery
There are many complaints in new Android smartphones for overheating – Tons of heating issues are reported about a huge number of mobiles like Lenovo K5 Note, Moto G5, Redmi Note 4, Redmi Note 3, Redmi 4, Mi A1, Samsung J3, Lenovo K8 Note, Gionee A1, Honor 8 Pro, Honor 6X, Oneplus 5T.
It doesn’t matter whether your phone has MediaTek or Qualcomm or Exynos processor some of the SOCs heat up. In the past, Oneplus 2 running on the Snapdragon 810 had heating issues. New processors based on latest 14 Nm manufacturing process are less prone to heat. (Ex. Snapdragon 625, 626, 636 and 660 and so on.)
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.
Heating is not an issue related to budget phones or all phones from a brand or make.
There can be a small fraction of models which have some software-hardware imbalance that 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 A6000 due to sound and heating issues.
Surprisingly, the replacement models just worked great.
So if one user had a bad experience with one mobile model, to categorize that model as bad is not correct. Several other users might as well have a positive experience with the model.
Is Heating During Gaming & Charging Normal?
Even my Samsung S7 sometimes heat up while playing intensive graphics games or when I put it on the charge. Also, most phones that come with fast charging support becomes hot during charging.
*Tip – Don’t use your phone when it is charging, only use if it is necessary. Also, to speed up charging you can turn off location and data and close all Apps.
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 VOLTE 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
If there are too many apps open on the mobile at the same time, it 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. The 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 to overheat 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.
4). App Notifications
They are other culprits to excessive processor use, turn the app notifications to the longer duration or just switch them off to make sure the apps are not working in the background.
To do this open the app like Times of India and go to the settings and turn off the notifications.
Or can Navigate to Settings>Notifications>Apps>turn off notifications.
5). 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 you get from the mobile phone manufacturers, to ensure bug fixes and keep all your apps up to 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.
6). Old battery or Non-genuine battery
Buy only the genuine batteries. Non-genuine batteries can wreak havoc on your smartphone’s working. There is a fluctuation of power from these and processor and Ram get insufficient or excess charge leading to faster battery drains.
Always get the genuine batteries either by contacting the service center or buy it from an authorized dealer for the mobile brand.
7). Only Enabled /WIFI / 4G/5G 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 when you are not using data or traveling.
Turn On WIFI /5G / 4G whenever required it will also reduce the load on the mobile processor and help it cool down faster.
8). 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.
9). The long duration of Graphics intensive Gaming sessions
If you are addicted to PUBG, Fortnite or other high graphics games, you may experience issues with your mobile sooner or later. If you are gaming too much on the mobile, this can impact the battery life as well as cause the phone to heat.
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 games push the processor and GPU to the limit. The increased processor/GPU load while Gaming generates a lot of heat.
If there is less space for the heat to escape, due to design or provisioning of vents, the mobile gets hot. Taking a break after 1 hour will make sure your mobile gets less heated and you are healthy too.
10). 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 the optimizations mentioned above.
Rooting and using a custom ROM and then underclocking 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.
When to Take Your Phone to Service Center?
You can do a factory reset and see if the phone still heats. This should be the first step to optimize performance. If the heating problem is persistent for many days, take it to the service center and ask them to check the device. You can also ask them to replace it.
If it is out of warranty or nothing else is working, then you can root your mobile. Moreover, install a custom ROM and see if the heating was OS related issue.
If it still heats you can try downclocking the processor to ensure that the boost clock is lower by 10-15% which may at least reduce the heating of the mobile. Downclocking also reduces the performance of the phone but it is still better than using a hot phone.
Very hot phones are susceptible to catch fire and burst, so it is advisable to get it checked.
11). Don’t Use the Smartphone when Charging to avoid Heating
This is the cardinal rule you must follow, must not play games or use data to watch videos when it is charging. The processor comes under a huge amount of stress and definitely the mobile will heat up due to this.
What about Non-Heating Mobiles what are the Best Choices?
Aforementioned, It is difficult to say which phones will heat less, your friend having the same model may not face heating issues and you may.
Best is to try these optimizations, however, if you still want phones with lesser heat look for the manufacturing process for the processor. Ideally in the current scenario should go for 14 Nm or 10/7 Nm process.
Here is a list of Non-Heating Phones with Processors You Can Buy.
- Xiaomi Redmi Note 7 – Snapdragon 660.
- Xiaomi Redmi Note 7 PRO – Snapdragon 675
- Realme 3 Pro – Snapdragon 710.
- Realme X – Snapdragon 710.
- Zenfone Max Pro M2 – Snapdragon 660.
