How to check battery health on Android

Introduction

Your Android phone's battery degrades over time, and keeping an eye on its health can help you understand why your phone might not be lasting as long as it used to. Unlike iPhones, Android doesn't have a single built-in battery health screen — but there are several ways to check it depending on your device.

Method 1: Built-in Battery Settings

Many Android manufacturers include battery health information in the settings:

Samsung Galaxy:

1. Open Settings
2. Tap Battery and device care
3. Tap Battery
4. Tap the three-dot menu (top right) and select Battery information
5. You'll see your Battery health status — it should read "Good" if the battery is in good condition

Google Pixel:

1. Open Settings
2. Tap Battery
3. Tap Battery health (available on Pixel 6 and later running Android 14+)

Other Android Devices:

If your device doesn't have a built-in battery health screen, try the dialler code method below.

Method 2: Dialler Code (Samsung)

Samsung devices support a hidden diagnostic menu:

1. Open the Phone app and go to the dialler
2. Type *#0228#
3. A battery status screen will appear showing voltage, temperature, and battery level

Note: This code may not work on all Samsung models or Android versions.

Method 3: Use a Third-Party App

Apps like AccuBattery or CPU-Z can give you detailed battery health information:

1. Download AccuBattery from the Google Play Store
2. Open the app and go to the Health tab
3. Charge your phone to 80–100% to allow the app to calculate your battery's design capacity vs actual capacity
4. The app will show your battery health as a percentage over time

Signs Your Android Battery Needs Replacing

• Battery drains much faster than it used to
• Phone shuts down unexpectedly even with charge remaining
• Battery percentage jumps around erratically
• Phone gets unusually hot while charging or in use
• The back of the phone appears to be bulging (swollen battery — stop using immediately)
