How to Check Phone Temperature on Android

Overheating phones is a common issue that can lead to poor performance, battery drain, and even permanent damage.

Thankfully, monitoring and controlling your Android phone’s temperature is easy with the right tools.

In this compete guide, we’ll cover everything you need to know about checking and regulating your phone’s temperature on Android.

Why You Should Monitor Your Phone’s Temperature

Extreme heat can cause multiple problems with your Android device:

  • Throttled performance – To prevent overheating, your phone may throttle the CPU and GPU speeds. This leads to lag, freezes, and slower app loading times.
  • Battery drain – Heat puts strain on the battery components, shortening its lifespan and causing faster power drain.
  • App crashes – Excess heat can force apps to close and prevent smooth operation. Games and video streaming apps are especially susceptible.
  • Hardware damage – High temperatures degrade silicon chips over time. The processor, RAM, and internal storage are most at risk of permanent failure.

By monitoring and controlling the internal temperature, you can avoid all these issues and extend your phone’s life.

Most Android devices start exhibiting problems at around 40°C/104°F and above.

Checking Temperature on Android

Android provides several ways to instantly check the live temperature of your device.

Let’s go through each method.

Using a Temperature Monitoring App

Specialized apps offer the easiest and most convenient way to check CPU and battery temperature on Android.

They display readings in both Celsius and Fahrenheit.

Some popular options include:

  • CPU Temperature – Lightweight app with temperature displayed directly on the status bar.
  • AIDA64 – Advanced diagnostics suite that shows CPU, GPU, battery, and other component temperatures.
  • Thermometer – Simple thermometer app for ambient, CPU, GPU, and battery temperature.

We recommend CPU Temperature for a quick overview and AIDA64 for maximum detail.

Both are free on the Google Play Store.

To use these apps:

  1. Download and install the temperature monitoring app of your choice.
  2. Open the app and check the current CPU temperature.
  3. For more details, consult the battery and individual component temperatures.
  4. Refer to the temperature periodically, especially when experiencing overheating issues or lag.
  5. Look for spikes over 40°C/104°F when under load.
  6. This may indicate cooling or software issues.

The major downside to these apps is the need to open them manually.

So it’s easy to miss temporary spikes.

We’ll cover widgets and status bar icons next for 24/7 monitoring.

Via Status Bar and Widgets

For at-a-glance temperatures directly on your home screen, use temperature widgets or enable the status bar icon in monitoring apps.

Here’s how to set them up:

Widgets

  1. Press and hold on to an empty section of your home screen.
  2. Tap “Widgets” and look for your temperature monitoring app.
  3. Drag the temperature widget to your preferred location. It will now display constantly.

Status Bar Icon

  1. Open your temperature monitoring app’s settings.
  2. Enable the “Status bar icon” or similarly named toggle.
  3. A small thermometer icon will now be visible in your status bar. Check it anytime.

The widget and status icon allow checking the temperature without opening any apps.

However, most lack detailed breakdowns by component. You’ll still need the full app for that.

Reading Temperatures in Diagnostics Mode

Every Android device has built-in diagnostics screens that are not normally visible to users.

They contain technical details like live temperatures that help with troubleshooting.

To view them:

  1. Open your phone dialer and enter *#0*# to launch diagnostics.
  2. Navigate to the “Kernel/Thermal” tab.
  3. Scroll down to view the current and maximum temperatures for the CPU, GPU, battery, and other components.
  4. Take note of any readings higher than 40°C/104°F when idle or 50°C/122°F under load.

The diagnostics screens provide the most comprehensive temperature overview possible without root access or additional apps.

However, the UI is very basic and temperatures are shown in Celsius only.

Using Rooted Device Apps

Root access allows installing apps that can read even more sensor data from your phone than usual.

Apps like Kernel Adiutor provide highly detailed temperature monitoring with root privileges.

To use specialized rooted apps:

  1. Unlock your phone’s bootloader and install custom recovery.
  2. Use Magisk to root your device. Follow guides carefully to avoid issues.
  3. Download Kernel Adiutor or a similar temperature app requiring root.
  4. Open the app and navigate to the temperatures tab to view read-only data.

Rooting leads to the highest level of hardware access possible.

But it also carries risks, like voiding your warranty and bricking your phone if done improperly.

Only attempt it if you need that extra data and understand the dangers.

Controlling and Lowering Phone Temperature

Once you know your phone’s temperature, you can take steps to lower it using both software settings and physical techniques.

Reducing System Heat Through Settings

Adjusting software configurations is the first step to running a cooler.

Here are some options to try:

  • Limit CPU speed – Reduce maximum CPU frequency in battery settings or use a CPU throttling app.
  • Stop background apps – Freeze or uninstall apps running in the background needlessly.
  • Enable battery saver – Use your phone’s ultra power saving mode to limit performance.
  • Lower brightness – Reduce screen brightness to around 30% to cut energy use.
  • Disable GPS/connectivity – Turn off location services, WiFi, Bluetooth, and mobile data when not needed.
  • Remove live wallpaper – Switch to a static wallpaper to reduce GPU load.
  • Stop wireless charging – Use wired charging to avoid extra heat from wireless coils.
  • Update software – Install the latest OS and app updates for potential heating fixes.
  • Factory reset – Wipe your phone if overheating persists after the above steps.

These tweaks reduce total energy consumption and therefore heat production.

Try them one by one to determine the impact.

Physically Cooling Your Phone

In addition to software, physical cooling methods can also lower extreme device temperatures:

  • Remove the case – Prevent the phone from insulating itself, especially in direct sunlight.
  • Point a fan at it – Direct airflow cools the phone passively without risky DIY methods.
  • Place it on a cold surface – Lay your phone down on a metal, glass, or tile surface to absorb the chill.
  • Wrap an ice pack in a towel – Applying an ice pack briefly draws heat away, but avoids moisture damage.
  • Immerse in front of the AC vent – Position the phone to receive concentrated cool air.
  • Switch off and rest – Allow your phone to fully cool down by powering it off for 1+ hour.

Avoid extreme cooling like refrigerators, as condensation can damage electronics.

The above methods work safely if your phone is overheating.

Preventing Overheating Issues

Prevention is the best solution for overheating problems versus reactive troubleshooting.

Here are some proactive measures:

  • Maintain case ventilation – Don’t use fully sealed cases without heat dissipation.
  • Update intensive apps – Game/video apps should be updated to the latest optimized versions.
  • Avoid direct sunlight – Don’t leave your phone baking inside a hot car.
  • Limit charger amperage – Stick to OEM chargers and avoid fast charging when overly hot.
  • Check for swelling – Visually inspect the phone for potential swollen battery issues.
  • Monitor phone lifespan – Performance phones often degrade after 18-24 months of use.
  • Clear app data/caches – Wipe temporary storage as maintenance to avoid bloat.
  • Factory reset periodically – Start fresh to clear any janky software issues.

Making temperature monitoring part of your regular device maintenance helps avoid most overheating problems.
