How to Check Battery Health on Android: What Your Phone Supports

To check battery health on Android, open Settings and look for a Battery health option under Battery. The exact menu depends on your phone's manufacturer, model, and software version. Some phones show a health status or estimated capacity, while others expose battery usage information without providing a built-in health percentage.

Do not confuse the battery percentage in the status bar with battery health. The percentage tells you how much charge remains right now. Battery health estimates how much capacity the battery can hold compared with when it was new. A battery usage screen shows which apps or system features have been using energy; it does not, by itself, measure the battery's remaining capacity.

Checking battery health across other mobile devices too? See our guides to checking iPhone battery health, checking iPad battery health, and checking Apple Watch battery health for their platform-specific menus.

How to check battery health on an Android phone

Start with your phone's built-in Settings app. Menu wording can differ, so treat these as places to look rather than a single path that works on every Android phone:

1. Open Settings.
2. Tap Battery. On some phones, battery options may be inside a device-care or battery-management section.
3. Look for Battery health, Battery information, or a similar item if your phone offers one.
4. If you find a health status or capacity estimate, read the explanation shown on the same screen. Note the exact wording and any model-specific guidance.
5. If you do not see a health option, open Battery usage to review what is consuming charge. Remember that this is a usage report, not necessarily a battery health test.

The labels in your Settings app may differ from this diagram. If the menu is missing, it does not automatically mean your battery is damaged; the phone may simply not expose a battery-health estimate in its standard settings.

How to check battery health on Google Pixel

Google documents a built-in Battery health feature for Pixel 8a and later. Google says this feature is not available on Pixel Tablet, and it specifically notes that Pixel 6a, Pixel 7, Pixel 7 Pro, Pixel 7a, Pixel 8, and Pixel 8 Pro do not show the Battery health status described in its guide. Feature availability is model-specific, so do not assume every Pixel has the same menu.

On a supported Pixel phone:

1. Open Settings.
2. Tap Battery.
3. Tap Battery health.
4. Read the displayed status, such as Normal or Reduced.
5. To see the estimated capacity, open Battery > Battery health > Battery capacity, where available.

Google describes Normal as capacity within normal limits and Reduced as remaining capacity below 80%. If a supported Pixel reports Reduced, Google recommends considering battery replacement. Treat this as Google's guidance for supported Pixel phones, not a universal threshold for every Android manufacturer or model. Read Google's full Pixel battery guide (opens in new tab) for the supported models and details.

How to check Pixel battery cycle count

On Pixel 8a and later, Google says you can find cycle-count and battery information by opening Settings > About phone > Battery information. The available information can include the battery's manufacture date and the date of first use. Google does not describe this same standard Settings route for every older Pixel model, so the menu may be absent on your device.

A charge cycle is cumulative use equal to 100% of the battery's capacity. It does not require one uninterrupted discharge from 100% to zero. For example, using 50% one day and another 50% later adds up to roughly one full cycle. Cycle count is useful context, but it does not independently tell you the battery's exact current capacity or diagnose every battery problem.

What if Android does not show Battery health?

If you cannot find a Battery health or Battery information entry, try these steps before assuming the battery has failed:

1. Check your exact phone model. Look up the model number in Settings > About phone, then consult the manufacturer's support guide for that model and software version.
2. Install available system updates. A compatible update may change the Settings layout or add device-specific features, but an update is not guaranteed to add a health percentage to every phone.
3. Check Battery usage. Review recent app and system consumption to see whether one app, the display, mobile network, or another component is using unusually large amounts of charge.
4. Use the manufacturer's diagnostic tool if available. Some Android brands provide hardware diagnostics or a battery status assessment. For example, Samsung documents battery diagnostics in Samsung Members and Device care, though options can vary by model and software version. See Samsung's diagnostic instructions (opens in new tab).
5. Seek manufacturer or authorized repair support if symptoms persist. This is especially important if the phone shuts down unexpectedly, becomes unusually hot during normal use, or the battery or phone casing appears swollen.

Do not treat a third-party app's estimate as an official battery-health reading. Apps can report the charging current, temperature, usage history, or estimates based on the data Android makes available to them, but they may not have access to the same battery-capacity data as the manufacturer's own diagnostics. A missing Settings option is not proof that an app can unlock an accurate hidden percentage.

Battery charge vs. battery health vs. charge cycles

These terms describe different measurements:

• Current charge: How much energy remains at this moment, usually shown as a percentage in the status bar or Battery settings.
• Battery health or capacity: An estimate of how much energy the battery can store compared with when it was new. Not every Android phone reports this as a percentage.
• Battery usage: A record of which apps or system components used power over a selected period. It helps investigate drain, but it is not a direct measurement of maximum battery capacity.
• Charge cycles: A cumulative measure of battery use. The phone may expose this value only on certain models, and many Android Settings menus do not show it.

A phone can have a high current charge while its battery has degraded over time. It can also have a battery with reasonable capacity while a particular app or poor signal is draining it quickly. Check the right measurement for the problem you are trying to solve.

How to investigate fast battery drain on Android

If your phone needs charging much sooner than it used to, use the battery usage screen to find patterns before deciding the battery itself is worn out.

1. Open Settings > Battery > Battery usage, or the equivalent menu on your device.
2. Review the apps and system components consuming the most power over the period shown.
3. Look for an app that has unusually high background activity compared with how often you use it. Update it, restrict background activity where appropriate, or uninstall it if you no longer need it. You can also audit your smartphone app permissions to control background refresh and location requests that consume power.
4. Check common contributors such as high screen brightness, a long screen timeout, location use, hotspot use, weak mobile signal, gaming, navigation, video recording, or a recent software update.
5. Restart the phone and install available app and system updates if drain began suddenly.
6. If the device continues to drain abnormally after these checks, consult the phone maker's diagnostics or support team.

Google's Android battery-life guide (opens in new tab) covers ways to reduce power use. Pixel owners can also follow Google's Pixel battery troubleshooting steps (opens in new tab), which explain how to check Battery usage and investigate unusually high consumption.

When should you consider battery service?

Consider professional advice when the battery runtime has become consistently much shorter, the phone shuts down unexpectedly, diagnostics report a problem, or the device shows physical signs such as a lifting screen or swollen casing. If the phone is swollen, stop using and charging it and arrange professional service; do not press, puncture, or attempt to remove the battery yourself.

There is no single battery-health percentage that applies to every Android phone. Follow the manufacturer's recommendation for your model and account for actual symptoms, warranty, and repair options. Google's below-80% guidance described above applies to its supported Pixel Battery health feature; it should not be presented as a universal Android rule.

Frequently asked questions

Can I check Android battery health without an app?

Sometimes. Start in Settings and look for Battery health or Battery information. Google documents these details on supported Pixel models, while other manufacturers may provide their own diagnostics. If the phone exposes only Battery usage, that screen can help investigate drain but does not necessarily show remaining battery capacity.

Why does my Android phone show battery usage but not battery health?

Battery usage and battery health are different features. Usage reports show where charge is going; health estimates the battery's capacity compared with when it was new. Whether the latter appears in Settings depends on the device and software support.

Is 80% battery health bad on every Android phone?

No universal threshold applies to every Android brand. Google's Pixel guidance uses a below-80% capacity status for supported Pixel models, but you should follow the service guidance for your exact phone rather than transferring that rule to all Android devices.

Does charge cycle count tell me exactly how much battery life is left?

No. Cycle count records cumulative battery use, but remaining capacity and real-world runtime also depend on battery age, temperature, charging habits, software, settings, and workload. Use cycle count as one piece of information, not a complete diagnosis.
