When you use your phone, it doesn’t overheat when used normally but when too many apps or say graphic-intensive apps are involved, overheating problem is just one of the thing you can be worried about. Although it might seem that overheating problem is not that severe but indeed it is because when the phone gets heated up, it deals with a varying of factors affecting the device’s performance, battery backup, and overall functionality of the device. This is why you must keep a tab on core temperature of the device but say that you did but it didn’t help, what do you do? Fortunately, you are in the right place as we are discussing the same here with respect to Koolnee but of course, you can apply it to other smartphones as well.

How To Fix Koolnee Overheating Problem – Troubleshooting Fix & Tips

Before you can actually commence knowing how to fix this issue, let us see what causes it in the first place. Smartphones are backed by batteries that enable it to do stuff by powering the SoC, GPU, and other components that run software on the device and so on. However, it is a basic Physics property that when there’s a moment, there’s heat generation and it is directly proportioned to each other. Processors come with throttling mechanism along with heat sink and other applications, however, sometimes the phone becomes too hot to handle. This is where the troubleshooting methods for fixing the overheating problem come into play.

Method #1: Give it a rest

You are holding your phone and observe that its temperature is rising. Since you know the usual temperature or at feel it when using it, a little change is easy to gauge and that is when you knew that the phone is heating up. In such a scenario, I would recommend you to stop whatever you are doing and give it a rest. Further, press the power button to shut down the phone for a couple of minutes when the device brings its core temperature to an ordinary level which is when you can restart the phone and it accordingly.

Method #2:  Prevent overusing the device

My smartphone offers 5+ hours of constant usage which I can extend if I divide the SoT throughout the day which involves playing heavy games and watching videos, music, working, calling, texting, etc. But hey, what good is a smartphone if you can’t use it as much as you want. Unfortunately, if you have that opinion about using the phone, you are basically overusing the device more than you should. The easy way to gauge if that’s true is to recall if the battery drains faster or if the SoT duration that you can find within Settings » Battery » Battery Usage is lower than usual. There is no rocket science here, prevent overusing the device and you could add a counter-point against the overheating problem.

Method #3: Check for apps & behavior

For this Koolnee overheating problem troubleshooting guide, I decided to form a single subheading for what we call ‘apps’. I know apps are useful on a phone but there’s more to the story than just useful apps. Unlike iOS, the Google Play Store offers almost all apps free with in-app purchases. This allows the user to install a string of apps irrespective of if they’ll use it anytime or not. Also, unwanted apps still consume storage of your device and might pop up by using RAM and another resource as well which adds to the surge. Moreover, there are power-hungry apps that consume more battery than others while some might be organic will some might be behaving abnormally due to bugs or viruses that infiltrated it. Anyhow, it is better to delete apps that you don’t need right now.

Method #4: Check for viruses

Hackers across the globe affect millions of devices including smartphones every year. They try to find out vulnerability or exploit a bug or release viruses using backdoors that either affects the user’s device by stealing data or crash it or cause hundreds of other possible problems on a device. Therefore, you must keep the phone away from viruses for which, you’ll need anti-virus programs on your device to scan and quarantine any threat if discovered.

Method #5: Upgrade apps/OS

One way to prevent hackers exploit devices is to simply update all the apps installed on your phone including both bloatware and third-party apps. Further, you must also upgrade the OS to its latest available update to prevent any software failure or incompetency caused due to viruses or bugs infiltrating the system causing it to shoot up the overall temperature to a critical ‘overheating problem’.

Method #6: Remove case or cover

A number of factors can contribute to the increased core temperature of the device. One of which is the phone case or cover which is made up of a variety of materials and there’s a possibility that one of the material or the case as a whole is causing the phone to suffocate or not letting the heat exchange from the surrounding. This builds up the internal temperature and at a point, it reaches a critical level or as said, ‘overheating problem’ comes into existence right here.

Method #7: Battery problem

Smartphones use Lithium-Ion or Lithium-Polymer batteries that have specific lifecycle after which, they tend to cease in performance. It is plausible that you are facing Koolnee overheating problem because the battery has run its course or it is faulty or any other reasons that could render battery as the problem. If it is a removable battery, you can simply switch it up with a new battery to verify if it makes any difference or not. Further, you can ask help from the service center to analyze the current battery and seek help for its repair and replacement, etc.

Method #8: Are you charging the phone properly?

Charging the phone improperly can cause serious problems in its lifecycle. But there’s a catch here. Some experts recommend using a full charge and discharge cycle that is you charge the phone only when it is nearly drained. Another way around is using 80:20 or 90:10 ratio where you charge the phone till the selected higher limit and use it till it drops to the lower limit only to charge it back. Then again, there is a group of experts that suggest keeping the battery above 50% makes it efficient and thus, you need to simply use all or any of these methods to cater to the one that suits your phone well.

Method #9: Purge all cache files

You thought this might not come but you know, cache files are behind most of the issues so I better keep it active in all our troubleshooting guides and since there is no harm in deleting these files so why not. You need to clear all app cache, system cache, and cache partition to steer clear of any bugs and issues that might have exploited the system due to corrupted cache files.

Method #10: Restore the device by master reset

It is undoubtedly the mother of all fixes when it comes to restoring the phone in case if you suspect software to be a problem. Here, you’ll need to take a backup of all the data ever stored on the device to prevent it from losing. Here is a specific procedure on how you can do it about.

  • Firstly, you’ll need to turn off the phone.
  • Now, press power + volume up to initiate the bootup procedure and hold it for a few seconds until an Android logo isn’t displayed on the screen.
  • Once you see an Android logo, let go of the buttons and wait for the menu to appear.
  • When in recovery mode, power button act as a selection key while volume rockers double as navigation keys.
  • You need to select ‘wipe data/factory reset’ and select ‘yes – delete all user data’ to do it.
  • Restart the device to see if the overheating problem is gone or not.

Method #11: Report It!

What else do you think you can do rather than reporting the issue to a service center if you can’t get the issue fixed using any of the methods prescribed above. Note that there are basically two service centers where you can report i.e. authorized and third-party where the former is little expensive but warranty friendly while the latter is easily available, cheap, but not warranty friendly so choose wisely.
