How to check your phone’s temperature?

Have you observed an unusual increase in your cellphone or battery temperature? If you’re concerned about your device’s temperature, you’re in the right place! Here are several methods to help you determine if your phone or battery is overheating.

Ways to Monitor Your Phone’s Temperature:

Listed below are four methods to check your phone’s temperature, especially if you’ve been wondering whether it’s running too hot or too cold lately.

Using feature code on the dial pad

We’ll attempt to access the battery information menu on your phone, a feature available on many Android devices through a specific code.

  1. Open your cellphone’s dial pad and enter ##4636##. If your smartphone supports this feature code, a screen will appear, offering various options. Find and select the Battery Information option.
  2. The displayed data will include information about your battery:
    • Battery Status: Indicates whether the battery is charging or full.
    • Power Plug: Shows the charging mode, such as AC (wall charger) or USB (computer).
    • Battery Level: Reflects the current charge level of the battery.
    • Battery Scale: Typically set to “100.”
    • Battery Health: “Good.” If the Battery Health is indicated as “unknown” or “unknown error,” there may be a battery issue. In such cases, try a power cycle (turning the phone off and on), enter the code again, and check Battery Information. If the issue persists, the battery may be defective.
    • Battery Voltage: Based on our research, Android cellphone battery voltage usually ranges between 3.7V and 4.2V.
    • Battery Temperature: Your phone’s temperature is reflective of the battery. Ideally, the battery temperature should be between 29°C and 43°C. If it exceeds 40 degrees, avoid engaging in resource-intensive activities. If the battery temperature is normal, focus on cooling down the phone to prevent overheating.
    • Battery Technology: Commonly listed as Li-ion (representing Lithium-Ion batteries used in most Android devices).
    • Time Since Boot: Indicates the duration since your phone was last started.

Physical inspection

It is strongly advisable to visually inspect your cellphone’s battery if you are concerned about its overall health. The methods mentioned earlier are generally accurate in assessing the battery’s condition. However, if your phone’s battery is not designed for user removal to avoid voiding the warranty, refrain from attempting to remove it. In cases where the backplate and battery are removable, you can take the following steps:

Carefully remove the battery and conduct a visual inspection. Place it on a flat surface and observe if it sits evenly or if there is any warping or bloating. If the battery does not sit flat and displays signs of deformation, it is recommended to replace it with a new one.

Device settings

To check your Android phone’s temperature using the Settings app, follow the steps outlined below:

Step 1: Open the Settings app on your Android phone and select the “System” option.

Step 2: Navigate to the “Battery & Performance” section.

Step 3: Tap on “Battery.”

Step 4: Here, you can view the battery temperature, along with the number of times the phone has been charged during the day. Additionally, you have the option to activate the battery saver and schedule when your phone will turn on and off.

By accessing the battery saver tab, you can address any battery-related issues and optimize battery performance. Essentially, the phone will close down power-consuming programs and switch to auto-brightness to conserve battery life.

Using a third-party tool (CPU Temperature)

While Android itself does not provide a direct function to display temperature readings, several apps available on the Google Play store can assist users in monitoring CPU and battery temperatures.

Numerous apps on the Google Play store offer tools to view CPU and battery temperature readings. One recommended option is “CPU Temperature,” which provides comprehensive features for examining and evaluating your phone’s temperature.

Here’s a guide on obtaining accurate temperature readings for your phone’s CPU and battery using the CPU Temperature app:

  1. Install CPU Temperature from the Google Play store and launch the app. It will display the current temperature of your phone’s CPU and battery.
  2. Navigate to the Changing Curve tab in the main menu to view a graph depicting changes in the CPU’s temperature and usage over time.
  3. Utilize the Settings tab to enable features such as a high-temperature alarm and a draggable CPU temperature overlay. The latter allows you to see the current CPU temperature without launching the app.
  4. Explore the Analyze tab, which tracks the temperature of your phone’s CPU while running specific applications. This feature helps identify applications contributing to the rise in your phone’s temperature.

CPU Temperature proves valuable in distinguishing whether it’s the CPU or the battery causing your phone to heat up. Keep in mind that there’s generally no cause for concern unless your phone’s CPU temperature hits 100 degrees, with normal working temperatures ranging between 30 and 50 degrees. For the battery, temperatures should not exceed 60 degrees, as the phone will automatically shut off if any of these thresholds are breached.

What causes the phone to overheat?

It’s important to consider what constitutes normal warmth and potential issues with overheating before delving further. Typically, your phone should not feel hot under normal circumstances. If you perceive excessive heat, it’s an indication that there might be an underlying problem that requires attention.

However, it’s essential to differentiate between warmth and overheating. It’s normal for your phone to become slightly warmer after extended gaming, lasting around 15 minutes. Nevertheless, if your phone triggers an overheating alarm or feels unusually hot to the touch, it warrants investigation.

In troubleshooting, you may have already closed applications or rebooted your device and even sought answers to error messages online. Commonly cited reasons for phone overheating often include:

  1. High display brightness.
  2. Prolonged use of Wi-Fi.
  3. Excessive gaming, often accompanied by warnings like “it’s not a game console.”

Yet, these explanations typically pertain to older phone models. Modern smartphones, including brand new Samsung devices, should not overheat for these reasons. If your current smartphone is exhibiting overheating issues and none of the standard reasons apply, other factors might be at play.

Here are a few potential causes to explore:

Direct sunlight exposure and a warm atmosphere

This is evident: your phone tends to warm up when exposed to direct sunlight, especially on sunny days. The sun’s UV rays can rapidly elevate your phone’s temperature when you’re outdoors.

Therefore, whenever you find yourself outside on a sunny day, it’s crucial to shield your phone from direct sunlight. Using an anti-shade phone case can effectively keep your phone cool.

Alternatively, opting for an anti-glare tempered glass instead of a phone case can also help prevent overheating, as tempered glass is a common culprit for phone temperature elevation when used in outdoor settings.

It’s not just sunlight; warm environments can also contribute to a quick rise in your phone’s temperature. Prolonged periods in heated settings, such as a hot car or a warm apartment, have the potential to cause your smartphone to overheat.

Overloading the processor

A computer and a smartphone differ primarily in the fact that PCs are equipped with internal fans to regulate processor temperature. In contrast, smartphones lack the capability to adjust their processing speed.

While cellphones can effectively dissipate heat, there is a threshold. Excessive open apps on a smartphone can overburden the processor, leading to overheating.

Common triggers for processor overload include prolonged video streaming on platforms like YouTube, Netflix, and Amazon Prime, extended gaming sessions, continuous video recording without breaks, and the use of live wallpapers.


If your phone is experiencing heating issues and you haven’t subjected it to direct sunlight or excessive processor usage, an unidentified infection may be the culprit.

Similar to computers, smartphones can be vulnerable to malicious software. Inadvertent installation of such software can lead to processor overload by running hazardous files in the background, resulting in issues such as overheating and potential shutdowns.

The same scenario can unfold on your smartphone. Malware infection can prompt the execution of apps, widgets, and malicious files in the background, overwhelming the processor and leading to overheating.

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

A heated battery in a cellphone doesn’t necessarily indicate a faulty or defective battery. It might signal an issue with the phone itself. Therefore, before opting to purchase a new battery (we’ll explore some suitable replacement options later in this article), it’s advisable to try some of the solutions provided on how to address a cellphone that’s heating up. This approach could potentially save you time and money in the long run.

If you’ve concluded that your phone’s battery is indeed malfunctioning and generating excessive heat, to the point of potential overheating, replacing it may be a prudent step. Preventing a heated battery from causing damage to your phone and avoiding future issues should be a priority.

What can you do about it?


The positive aspect is that the manufacturer’s warranty, designed to address defective or malfunctioning equipment, typically extends coverage not only to your mobile phone but also to your cellphone’s battery in many cases. If your battery, without any physical or liquid damage, falls within the one-year timeframe, there’s a high likelihood that you may qualify for a complimentary replacement battery. To explore this option, contact your service provider and inquire about the warranty specifics for your cellphone. If needed, they can liaise with your cellphone manufacturer to discuss potential replacement solutions.

It’s essential to be aware that most cell phones and their batteries feature an LDI (Liquid Damage Indicator) located on the device. This indicator changes color, typically from white to pink or red, if exposed to dampness or liquid. If the LDI on your battery shows any pink or red, indicating liquid exposure, it is no longer covered under warranty. In such a scenario, purchasing a new battery would be necessary.

Purchasing a replacement battery

Another benefit of opting for battery replacements is that, based on the type of cell phone you own, new batteries are frequently available at affordable prices. If you are in need of a new battery, the most recommended shopping destination is online, where you can consistently discover cost-effective deals on platforms like Amazon or eBay.
