How to Check Battery Health on Android
If your phone’s battery is struggling to last the day, it might be time for a battery health check. This can also help when you’re buying a used smartphone. iPhones have had thebattery health featurefor a while, and, Android is finally catching up.
Android 14 has new BatteryManager APIs to keep a tab of your phone’s battery health, cycle count, charging status, manufacture date, and more. Unfortunately, you can’t check the battery health and other details in settings yet. For that, you’ll need to use a third-party app and grant ADB (Android Debug Bridge) permissions.

Check Battery Health Using aBattery on Android 14
Below, I’ve used the aBattery app and Shizuku to check my Pixel 8 Pro’s battery health. So before you begin, you can download and install both apps on your Android 14 running phone.
Download:aBattery app
Download:Shizuku
Let’s look at the steps:
Step 1: Turn On Developer Options
On your phone, head toSettings>About deviceand tap theBuild numberseven times. You’ll see a ‘You are now a developer’ message. After that, close the settings.
Step 2: Set Up Shizuku app
1.Open the Shizuku app. Tap onPairing>Notification Options.
2.Turn on the toggle forAll Shizuku notifications. Then, return to Shizuku and tapDeveloper Options.
3.In Developer options, chooseWireless Debugging. Toggle onUse wireless debuggingand tapAllow.
4.Next, tapPair device with pairing code. Shizuku will automatically pop up – enter the pairing code shown on your screen.
5.Head back to Shizuku and tapStart.
Step 3: View Battery Health in aBattery app
Open the aBattery app on your Android phone. Tap onMaximum Capacityand then tapAllow all the timewhen prompted. You will see your phone’s current battery health (maximum charge holding capacity). For example, my Pixel 8 Pro shows a maximum capacity of 99%. That means, it can hold up to 99% of its original charge capacity.
Alternatively, You Can Use Batt app on Android 14
Batt is another app that shows battery health and status information on devices running Android 14. Like aBattery, you’ll need to enable developer options and set up Shizuku app as we did above. Get the app and install it on your phone.
Download:Batt
Here’s how to use it:Open Batt app, tapLet’s Go> tapAllow all the timeto grant Shizuku access. You will see your phone’s current battery health alongside charge cycles, manufacturing date, and first usage date.
Unfortunately, neither aBattery nor Batt works on Samsung Galaxy phones due to compatibility issues with One UI. Also, the accuracy may vary across devices – these apps only report what the operating system tells them, which further depends on data reported by specific components on your phone.
Don’t Have Android 14? Check Battery Health Using AccuBattery
AccuBattery app uses its custom algorithm to estimate your battery health. It learns the battery’s actual design capacity and then measures how much charge it accepts during each charging session.
Over the course of 4-5 charging sessions (which usually takes about a week), it’ll compare the actual charge capacity to the design capacity. This is how it estimates your battery degradation and current battery health percentage. You can get the AccuBattery app from the link below and install it on your phone.
Download:AccuBattery
Here’s how to use it:Open AccuBattery app and allow it permission to run in the background. Charge your phone normally. After you’ve completed a few charge cycles, the app will show the phone’s battery health. It gets accurate as you complete more charge cycles.
In the screenshots below, my Samsung Galaxy S23 Ultra’s battery has an estimated 92% health based on the last five charging sessions.
AccuBattery also provides insights into battery capacity trends and wear over time. However, note that this data will be reset if you reinstall AccuBattery or perform a factory reset on your phone.
Also, remember that battery health readings aren’t always 100% accurate. You may find an error margin of +/- 5%. This is normal, considering there’s always some margin of error, and lithium-ion batteries don’t always have the exact capacity listed on the label. That’s why manufacturers often mention design capacity (theoretical maximum) alongside full charge capacity (typical usable capacity).
Keeping Battery Healthy for a Longer Time
Battery degradation is inevitable, but there are ways to slow it down and keep your battery healthier for longer:
If your phone’s battery health has dipped down to 70-80% of its original capacity, you may notice unexpected shutdowns, performance dips when running heavy games or apps. If this gets annoying, it’s probably time to consider a replacement. An authorized service center can help you get a fresh battery and make your phone feel like new again.
