How to Check Battery Health & Cycle Count on Android (2026)

Unlike iOS, which centralizes battery health percentage inside a single settings menu, Android handles battery diagnostics differently across manufacturers. Modern versions of Android (Android 14, 15, and 16) include native cycle counting, while brand skins like Samsung One UI, Xiaomi HyperOS, and OnePlus OxygenOS use proprietary diagnostic menus and hidden telemetry logs.

A charge cycle represents one full discharge of 100% battery capacity. Because lithium-ion cells lose capacity after 500 to 800 cycles, knowing your exact cycle count tells you whether daily battery drain stems from an aging battery or rogue background apps.

Here is how to check your battery health and cycle count across every major Android brand.

Google Pixel: Native Battery Information (Android 14 & Newer)

Google built native battery cycle tracking directly into stock Android.

1. Open Settings on your Pixel.

2. Scroll down and tap About phone.

3. Tap Battery information.

4. You will see:

•  Cycle count: The total number of complete charge cycles completed.

•  Manufacture date: The physical date the cell was assembled.

•  First use date: The date the phone was first powered on.

If your cycle count is below 400, your battery is in prime condition. Crossing 800 cycles indicates your battery has likely degraded to roughly 80% of its original design capacity.

Samsung Galaxy: Samsung Members Diagnostic & One UI

Samsung restricts raw cycle count visibility in standard menus, but provides hardware testing through its built-in diagnostics suite.

Method A: The Samsung Members App

• 1. Open the pre-installed Samsung Members app.

• 2. Tap the Support tab at the bottom right.

• 3. Under Diagnostics, tap Phone diagnostics.

• 4. Scroll down and select Battery status.

• 5. The system will run a test and display your Life rating:

•  Good / Normal: Operating at acceptable capacity.

•  Action Required / Weak: The battery has experienced high degradation and warrants replacement.

Method B: One UI 6 & 7 Battery Information

On recent Galaxy models running updated One UI versions:

• 1. Go to Settings > About phone.

• 2. Tap Battery information.

• 3. Review your Rated Capacity vs Typical Capacity (e.g., 4,855 mAh rated vs 5,000 mAh typical).

Xiaomi, Redmi & POCO: The Hidden Dialer Code

Xiaomi devices running HyperOS or MIUI feature an internal hardware engineering menu accessible via phone dialer codes.

• 1. Open the default Phone / Dialer app.

• 2. Enter the following code exactly:

⁠*#*#6485#*#*⁠

• 3. A diagnostic screen titled Battery and Charger Info will pop up immediately.

• 4. Locate the following system keys:

Diagnostic Code	Technical Meaning	Ideal Value
MF_02	Total charge cycle count	Under 500 cycles
MB_60	Battery health status	“Good”
MF_05 / MF_06	Current capacity vs factory design capacity	Above 80% ratio

Universal Method: Read Battery APIs with Shizuku & aBattery

If your phone’s manufacturer hides cycle stats, you can read the Android system battery manager directly using Shizuku (wireless ADB permissions) and aBattery (open-source reader). This method requires no rooting or PC.

What Your Cycle Count Numbers Actually Mean

Cycle Count	Estimated Health	Condition & Recommendation
0 – 250 Cycles	95% – 100%	Like New. Full-day endurance; peak performance.
251 – 500 Cycles	85% – 94%	Normal Wear. Minor drop in screen-on time; no action needed.
501 – 800 Cycles	80% – 84%	Degraded. Noticeable battery drain; top-ups needed during the day.
800+ Cycles	Under 80%	Service Recommended. Risk of sudden shutdowns; replace battery.

Frequently Asked Questions

Quick answers to common questions

Can third-party battery apps accurately measure battery health?

Apps like AccuBattery provide reliable estimates, but only after tracking dozens of full charge sessions over several weeks. Methods using native system menus, dialer codes, or ADB read the device's hardware Coulomb counter directly from the kernel, giving an immediate, tamper-proof reading.

Does fast charging increase my cycle count faster?

No. Cycle count is strictly tied to energy consumed and replaced. Discharging 50% today and 50% tomorrow equals one cycle, regardless of whether you recharged with a 10W standard charger or a 100W fast charger.

At what cycle count should an Android battery be replaced?

Most Android manufacturers engineer batteries to maintain 80% health at 800 complete cycles. Once past 800 cycles, internal resistance increases, leading to sudden battery percentage drops and thermal throttling under load.
