Once I used my smartphone’s flashlight for a while because I needed to light my way in a power outage. Since I was holding it by the sides, I didn’t realize how hot my phone was getting. When I finally remembered where I put the flashlight for these kinds of situations, my phone was so hot I couldn’t even hold it in my hand anymore.
There are always going to be situations or apps that cause our devices to overheat, but knowing how to cool down a hot Android device is a must. The first thing we have to figure out is where the heat is coming from. This is going to determine where the problem is located which will help us find the right solution.
Don’t Use Third-Party Chargers and Cables
The micro-USB cable-chargers shared by most Android devices are great largely because they’re universal, but that doesn’t necessarily mean you should just use any old cables and chargers for your phone. If your phone overheats while charging, you may want to look into this.
Different chargers have different wattage and are optimized for different devices. Ideally you should use official chargers and cables from your phone manufacturer, but official hardware for other phones should be okay too. Avoid cheap chargers from eBay that cost under $1 and third-party hardware from obscure brands.
Cool Your Android Device with Cooler Master
Cooler Master is an app that helps you cool down your device when you feel that it’s getting too hot. When you launch the app, the first thing you are going to see is the temperature of your device.
Below the temperature the app will also inform you of the ARM and CPU percentage. At the very bottom you should see a button that says “Detect Overheating Apps.” After tapping that it will scan your device and tell you what apps are causing your phone to overheat.
Keep Your Device in a Cool Place
Where you put your device is also important in trying to cool it down. There’s no point in using Cooler Master if you’re going to put it near your window where it will get direct sunlight. To cool your device even more, try taking it out of its cover so the heat has a chance to escape. Some cases have a tendency to keep the heat in.
Update or Uninstall Your Apps
You should always keep your apps up to date because apps always bring bug fixes, and it can correctly fix any problems that were overheating your device. You should also look through your long list of apps and decide which ones you haven’t used in a long time. Getting rid of unnecessary apps can really help to cool down a hot device. Also, if there is an app that you can’t live without and it is causing you problems, consider switching to an alternative. With tens of thousands of apps in the Play store, there is bound to be a better app than the current one.
Put Your Device in Front of a Fan
Just like most of us have a base with a built-in fan for our laptops to keep them cool, an Android device will also appreciate a fresh breeze. You might feel a little silly doing this or even get some weird looks from those passing by, but it will help to cool your device down. I have done this, and it has worked for me, but when I do this I usually turn off my phone first for faster results.
Never Cool Down Your Android Device this Way
If your device is really hot, you might be tempted to put it in the freezer or fridge just for a minute or two. You might even have a timer on so you can take it out on time, but this is what the experts call ‘an awful idea’ since your device runs the risk of collecting moisture, or you might even strain the components.
How to Prevent Your Android Device from Overheating
Now that we know how to cool our devices down, wouldn’t it be great if we didn’t have to waste time doing that in the first place? That’s why there are certain things we should avoid doing if we want to keep our phone or tablet nice and cool.
If you want to prevent your Android device from overheating, you should:
- Take out and inspect your battery from time to time and make sure it’s not leaking or bloated. Changing your device’s battery every one to two years will increase your phone’s life and decrease overheating.
- Remove the case when charging.
- Disable unwanted features.
- Lower your camera settings if they are too high; they can help to prevent your phone from overheating.
- Try not to play games for too long.
When my phone gets too hot, I automatically turn it off until it cools off. After that, I follow the tips mentioned above because my main goal is to cool down my phone, and turning it off for a few minutes always does the trick. How do you keep your Android device cool? Let us know in the comments.
