Battery health refers to the condition of your smartphone’s battery. It’s a measurement of its capacity compared to when it was new. As batteries age and go through more charge cycles, their capacity to hold a charge diminishes, resulting in decreased battery life.

Before delving into the guide on how to check the battery status on Android, let’s clarify that wear and tear on a chemical battery is normal. With each cycle, your device will discharge a bit more quickly.

It’s imperceptible when you’ve just purchased the device, but over the course of two to three years of usage, its battery will lose up to 30% of its capacity. Sometimes even more if used carelessly.

The degree of wear of the battery of an Android gadget increases when:

  • The battery is more than three years old (since the time of production);
  • The device has been actively used;
  • During usage, no one thought about why it’s not advisable to charge it in freezing conditions or store it in a discharged state.

Additionally, keep in mind that lithium-ion batteries can heat up to around 50°C under moderate smartphone usage and then cool down to 25–30°C. At these temperature levels, the device’s wear occurs steadily and predictably. If the battery regularly overheats above 50°C, even during standby, it’s best to consult a specialist.

Smartphone batteries degrade over time, impacting performance and longevity. To ensure a smooth experience, learn how to assess battery health using built-in tools, third-party apps, or specialized equipment. While the exact steps vary based on Android version and manufacturer, these methods are accessible to all users.

Checking Battery Health on Android

Using Built-in Settings

Android doesn’t provide a direct, built-in method to check the physical health of the battery. However, it does provide tools to check the battery usage and performance, which can indirectly indicate battery health.

To check the battery usage:

  • Open “Settings” on your Android device.
  • Navigate to the “Battery” section to view battery usage.
  • Check for unusual energy consumption and consider visiting a service center if needed.

This will show you a list of apps and services and their respective usage of your battery. If you notice an app consuming more battery than usual, it may be responsible for draining your battery quickly, not necessarily indicating a fault with the battery itself.

For instance, if you notice significant spikes in energy consumption on the activity graph that don’t align with your usage of games or resource-intensive apps, it might be a good idea to visit a service center.

Using Dial Codes

Some Android devices support dial codes that can be entered into the Phone app to access hidden diagnostic features. One such code may provide information on your battery’s health.

To check the battery using software, you can access the service menu:

  1. Open the “Phone” app to dial a number.
  2. Dial ##4636## in the Phone app.
  3. Select “Battery Information” to get an approximate assessment of battery condition.

Examine the battery capacity and other indicators. Based on the information provided by the built-in system tools, you won’t be able to make precise conclusions about the battery’s condition, but you can use this data for a rough assessment.

Note: Not all Android phones support these dial codes, and the information you get from them should be taken as a guide rather than a definitive assessment. For detailed steps and accurate information, consult manufacturer guidelines and user manuals.

Is the casing deformed?

  • Inspect for casing deformities, overheating, or screen abnormalities;
  • If the battery is swollen, its “bump” presses against other components of the smartphone or tablet;
  • The back cover shows signs of looseness (creaks, gaps);
  • The screen might accidentally respond to touches or have reduced touch sensitivity;
  • The display might exhibit color distortions, changes in backlight, or cracks on the glass.

Is the device overheating?

  • A worn-out battery can sometimes overheat without reason (high temperatures are generally bad for Li-Ion batteries);
  • After the smartphone or tablet have been idle with no processor load, you notice the device feels hot to the touch;
  • If the device used to not heat up significantly but now quickly discharges and heats up;
  • Occasionally, background processes can cause heating (in this case, we recommend ensuring it’s not a battery issue by performing an Android software reset).

Are there any other signs?

  • Rapid discharge and shutdown (e.g., from 30% to 1% and then it turns off);
  • Discharging in a sporadic manner (drops suddenly from 100% to 92% and holds the charge for a long time; sometimes calibration through a prolonged charge helps);
  • Sticking at a certain percentage while charging (often, this problem can be fixed through software);
  • If calibration and other methods don’t work, and the battery charge indicator regularly malfunctions, there’s a high probability of physical wear and tear (replacement is recommended);
  • A deteriorating battery is also indicated when it struggles to hold a charge (charges very slowly with any charging device at room temperature or doesn’t charge fully).

  • Update your device regularly for optimal performance.

Understanding and maintaining your battery’s health is crucial to ensure a smooth Android experience. By following these steps and tips, you can ensure your battery is in top shape and extend the life of your Android device.

FAQ: Checking Android Phone Battery Health

How can you check if the battery capacity has decreased on Android?

There’s nothing more accurate than professional equipment for measuring the capacity of lithium-based batteries (for example, devices like the Cadex testers from Canada). If you have the necessary skills, you can use a multimeter and USB testers.

For self-checking battery health, you can use certain Android apps. Here’s a list of what we’ve personally tested on Android device batteries (with brief reviews and differences linked, and we’ve indicated whether Root access is needed):

  • 1st place: AccuBattery
  • 2nd place: BatteryGuru
  • 3rd place: CPU-Z

Can you use system utilities to check how much the battery capacity has decreased on Android?

A more accurate battery check on Android is indeed performed using built-in tools. Google relies on utilities to monitor battery health. However, in most interface versions, this function is locked from regular users’ access.

On some smartphones and tablets, battery statistics (along with temperature and wear) can be accessed through the service menu. For instance, try entering the well-known code ##4636## (or simply remember ##INFO##) for Android. However, this doesn’t always work or the displayed information might be inaccurate.

I want to check my battery’s status with an Android app, but they ask for Root access. Why?

If you need extended statistics and battery testing, apps might require Root permissions. Objectively, it’s not recommended to grant Root access to unknown and unverified apps (there have been instances of battery checking apps being used for fraudulent activities).

For a regular battery capacity check, you don’t need Root access. The statistics will accumulate over several charge and discharge cycles. Graphs will clearly show the degree of wear and the actual battery characteristics.

My phone is brand new, yet apps and the system indicate high wear (over 50%) – why?

If a newly purchased smartphone or tablet wasn’t fully charged to 100% (as it should be) and was immediately discharged until shutdown, or if it wasn’t charged for some time after that (and remained discharged), the software statistics will be inaccurate.

Perform a calibration. Almost certainly, this is a software issue and the battery isn’t truly worn out. After a month of active usage and regular charging-discharging, the wear percentage will adjust. Some models might require a firmware update, but we don’t have an exact list.

My smartphone behaves strangely – sometimes it won’t charge, sometimes the screen goes black, sometimes it freezes. What’s wrong, doctor?

Interestingly, the battery can indeed affect the functioning of the system board, processor, and screen. As soon as the battery fails to provide the required voltage, anomalies in electronic behavior and various unexplainable problems start occurring.

However, don’t rush to buy a new battery just to check. It’s better to take the device to a reliable service center for diagnostics. If they confirm battery issues, then you can replace it and make sure to request a warranty for the new battery.
