Have you noticed that your cell phone or battery is getting a little hotter than usual? When it comes to checking your battery’s temperature, you’re in the perfect place! To help you figure out whether your phone or battery is overheating, here are a few ways you may use to narrow things down.

How to check your phone’s temperature?

Below we have listed four ways you can check your phone’s temperature if you have lately been skeptical about whether your phone’s temperature is either too hot or too cold (mostly too hot).

Using feature code on the dial pad

We’ll try to access your phone’s battery info menu. Many Android devices have a feature code for checking the battery.

Begin by accessing your cell phone’s dial pad and typing in *#*#4636#*#*. If your smartphone works with this feature code, a screen should appear allowing you to select from a few options. Locate and open the Battery Information option.

Then you should see a lot of data regarding your battery, like:

  • Battery Status: should display charging or full.
  • Power Plug: indicates charging mode, AC (wall charger), USB (computer).
  • Battery Level: indicates the battery’s charge level.
  • Battery Scale: “100”
  • Battery Health: “Good”. You may have a battery issue if your Android’s Battery Health shows “unknown” or “unknown error”. If you see anything other than “Good,” we recommend doing a power cycle (turning the phone off and back on), entering the code again, and checking the Battery Information. If it still doesn’t work, the battery may be defective.
  • Battery Voltage: As far as our research goes, the battery voltage of an Android cell phone is usually between 3.7V-4.2V.
  • Battery Temperature: Essentially, your phone’s temperature reflects your battery’s. The battery temperature should be between 29°C and 43°C. However, if the battery temperature exceeds 40 degrees, you should stop playing high-resolution games and apps. If your battery temperature is normal, the next step is to cool down the phone’s body. You should know how to prevent phone overheating.
  • Battery Technology: Li-ion (because of the common Lithium Ion batteries found in the majority of Android devices).
  • Time Since Boot: indicates the time since you last started your phone.

Physical inspection

A visual inspection of the battery is strongly recommended if you are concerned about the health of your cell phone’s power source, as the methods outlined above are usually pretty accurate in determining the state of the battery. To avoid voiding your phone’s warranty, don’t attempt to remove the battery if it isn’t built to allow you to do so. However, if the backplate and battery are removable, you should remove the battery and perform a visual inspection on it.

You can tell if anything is warped or bloated if you put it on a flat surface and watch if it sits flat or if it sways. If it doesn’t sit flat and the battery is out of shape, I recommend that you get a new one.

Device settings

You can check your phone’s temperature right from your Android’s Settings app if you follow the procedures detailed below:

Step 1: Go to the Settings app on your Android phone and select System.

Step 2: Navigate to the Battery & Performance section.

Step 3: Now tap on Battery

Step 4: From here, you can see the battery temperature as well as how many times the phone has been charged during the day thus far. Additionally, you may turn on the battery saver and set a timetable for when your phone will turn on and off.

If you go to the battery saver tab, you will be able to correct any battery problems and maximize battery performance. Essentially, the phone shuts down programs that consume battery life and switches to auto-brightness to conserve battery life.

Using a third-party tool (CPU Temperature)

In order for the user to see the temperature readings, Android does not have a function that displays it directly. However, many apps are available for download from the Google Play store that can assist you in viewing the temperature readings from the CPU and battery.

Many apps are available for download from the Google Play store that can assist you in viewing the temperature readings from the CPU and battery.

For example, CPU Temperature is an ideal option because it has all of the tools that you will require in order to examine and evaluate the temperature of your phone.

Here’s how to get an accurate reading of the temperature of your phone’s CPU and battery using CPU Temperature:

To use CPU Temperature, first install it on your phone and then launch it. It should show you the current temperature of your phone’s CPU and its battery.

A graph showing changes in the CPU’s temperature and usage readings overtime may be found by selecting the Changing Curve tab from the main menu.

The following features, such as the high-temperature alarm and a draggable CPU temperature overlay, can be enabled on the Settings tab. The latter is a feature that would be quite useful because it would allow you to see the current temperature of your phone’s CPU without having to launch the app.

At the end of the day, the app contains an Analyze tab that maintains track of the temperature of your phone’s CPU when it is running any application. This will assist you in determining which applications are causing your phone’s temperature to rise.

As a result, the next time your phone gets hot, CPU Temperature will assist you in properly determining whether it is the CPU of your phone that is heating up or whether it is the battery.

Furthermore, there is no need to be concerned until the CPU temperature of your phone hits 100 degrees, and the usual working temperature should be between 30 and 50 degrees. When it comes to the battery, the temperature should not be higher than 60 degrees. It will automatically shut off if any of the temperature thresholds listed above are breached.


What causes the phone to overheat?

It’s worth pausing to consider what’s hot and what isn’t before moving on. Under normal circumstances, your phone should not be hot. However, if you feel your phone is getting heated, then you may have a problem to fix.

Warm, on the other hand, should not be interpreted as hot. It’s understandable for your phone to get somewhat warmer after 15 minutes of gaming. However, if your phone displays an overheating alarm or feels unusually hot to the touch, you should look into it.

To troubleshoot, you’ve probably already closed a few apps or rebooted your device. Perhaps you’ve even looked up a few error messages on Google.

You’ll almost always come across a list of the same old reasons for your phone overheating:

  • The brightness of your display is set too high.
  • Your Wi-Fi has been turned on for an excessive amount of time.
  • You’ve been playing too many games (often accompanied by the warning “it’s not a game console”).

However, these arguments are only applicable to older phones. For any of these reasons, no smartphone on the market today should overheat. Other factors are most likely to blame if your brand new Samsung phone is overheating. Of course, it doesn’t matter what brand of phone you have; now, if you are wondering if none of these reasons listed above apply to your smartphone, then what is causing it to overheat?

Here are a few possible reasons:

Direct sunlight exposure and a warm atmosphere

This is self-evident. Your phone warms up due to direct sunlight exposure most of the time. When you’re outside on a sunny day, the sun’s UV rays can quickly heat up your phone.

So, whenever you go out on a bright day, make sure your phone is protected from the sun. You can keep your phone cool by using an anti-shade phone case

You can also use an anti-glare tempered glass instead of a phone case because tempered glass is the main cause of phone overheating when used outside.

Not only the sun but also warm situations can quickly raise the temperature of your phone. Long periods of time in a heated setting, such as a hot automobile or a hot apartment, can cause a smartphone to overheat.

Overloading the processor

A computer and a smartphone vary primarily in that PCs have internal fans to keep the processor cool. A smartphone, on the other hand, lacks the ability to slow down its processing.

Although cellphones are capable of dissipating heat, there is a limit. When a smartphone has too many apps open at the same time, the processor might become overworked, causing the phone to overheat.

Some of the most common causes of processor overload are watching series and shows on YouTube, Netflix, and Amazon Prime, playing games for hours on end, or filming long videos without pausing, and using live wallpapers.


If you haven’t exposed your phone to direct sunlight or aren’t overtaxing its processor, an unidentified infection could be the source of your phone’s heating issues.

It should come as no surprise that, like computers, smartphones may be infected with malicious software. When this software is installed unintentionally on a computer, it might cause it to shut down and overburden the processor by running hazardous files in the background.

The same thing can happen on your smartphone. When a phone is infected with malware, it can execute apps, widgets, and malicious files and processes in the background, overloading the processor and causing it to overheat.

If your phone is overheating, the battery could be the problem

A heated battery in a cell phone does not always mean the battery is faulty, defective, or malfunctioning. It could imply a problem with the phone itself, so before you go out and buy a new battery (we’ll go over some decent replacement options later in this article), try some of the solutions given under how to fix a cell phone that’s getting hot. It may save you some time (and possibly money) in the long run.

If you’ve determined that your phone’s battery is malfunctioning and is getting warm, if not hot enough to cause overheating, you may need to consider replacing it. You don’t want a heated battery to damage your phone and cause you more problems in the future.

What can you do about it?


The good news is that the manufacturer’s warranty, which covers defective or malfunctioning equipment, should cover not just your mobile phone but also your cell phone’s battery for many people and situations. If your battery has no physical or liquid damage and is less than a year old, there’s a strong chance you’ll be able to acquire a replacement battery for free. Call your service provider and inquire about the warranty on your cell phone. They can contact your cell phone maker for possible replacement choices if necessary.

Note that most cell phones and cell phone batteries will have an LDI (Liquid Damage Indicator) somewhere on the device that will change from white to pink or red if exposed to damp or liquid. If the LDI on your battery has been triggered and includes any pink or red, it is no longer covered under warranty, and you will need to buy a new battery instead.

Purchasing a replacement battery

Another advantage of battery replacements is that, depending on the cell phone you use, new batteries are often cheaply priced. If you need a new battery, the best place to shop is online, where you can usually always find a decent deal on sites such as Amazon or eBay.
