    How to Check and Improve Your Android Battery Health

    Android phones give you detailed battery health information — here's how to find it, understand what the numbers mean, and extend your battery life.

    In this guide (5 steps):

    1. 1.Check Battery Health on Samsung Galaxy
    2. 2.Check Battery Health on Google Pixel
    3. 3.Use AccuBattery for Detailed Tracking (Any Android)
    4. 4.Turn On Battery Optimization
    5. 5.When to Replace the Battery
    1

    Check Battery Health on Samsung Galaxy

    ~24s
    Open the Samsung Members app (search for it in the Galaxy Store or Google Play). Tap "Support" → "Phone diagnostics." Tap "Battery" or "Battery status." The app shows your battery health percentage and capacity. You can also go to SettingsBattery and device careBattery, which shows usage patterns and charging optimization options.

    Quick Tip

    If you don't have Samsung Members installed, search for it in the Galaxy Store app, not Google Play.

    2

    Check Battery Health on Google Pixel

    ~15s
    Go to SettingsBatteryBattery health. Google Pixel phones show battery health directly in Settings as a percentage. "Good" is above 80%. Adaptive Charging (charging slowly overnight) is also here — turning it on reduces battery aging from charging.
    3

    Use AccuBattery for Detailed Tracking (Any Android)

    ~16s
    Download AccuBattery free from Google Play. Open it and tap "Health." The app monitors each charge cycle and estimates battery wear over time. It's most accurate after several charge cycles have been recorded — give it a week of normal use to build a baseline.
    4

    Turn On Battery Optimization

    ~23s
    Go to SettingsBatteryBattery optimization (or "App battery usage"). Apps set to "Unrestricted" can drain battery in the background. Tap each app and choose "Optimized" unless you specifically need it running constantly in the background (like navigation or music apps).

    Quick Tip

    Samsung phones have "Adaptive power saving" under SettingsBattery and device careBatteryPower saving — turning this on automatically adjusts settings based on usage.

    5

    When to Replace the Battery

    ~21s
    If battery health is below 80% and you're consistently running out of power by mid-day, replacement is worth considering. Contact your phone manufacturer's service center, visit Best Buy Geek Squad, or find a local phone repair shop. Get a quote — for older phones, a new battery often costs less than a new phone and extends device life by 1-2 years.

    Every rechargeable battery gradually loses its ability to hold a charge over time. After a couple of years of daily charging, your Android battery may hold only 80-85% of its original capacity — meaning it runs out faster than it used to. Knowing your battery health helps you decide whether a battery replacement makes sense.

    Unlike iPhones, which have a standardized "Battery Health" percentage in Settings, Android battery health information varies by phone brand. Samsung phones show battery health in the Samsung Members app or via a built-in diagnostic. Google Pixel phones show it in Settings. Some brands bury it in hidden service menus.

    For Samsung phones (the most common Android brand), the Samsung Members app — available free in the Galaxy Store or Google Play — includes a diagnostic tool that reports battery health as a percentage. 100% is new. Most phones remain above 95% for the first year, then gradually decline. Below 80%, you may notice significantly shorter battery life between charges.

    For all Android phones, Google Play services also store battery health information accessible through some third-party apps like AccuBattery, which tracks charge cycles and estimates battery wear over time.

    Beyond checking health, there are practical steps to slow battery aging: avoid frequently letting the phone drain to 0%, keep it away from extreme heat (a hot car in summer causes significant battery damage), and avoid keeping it at 100% charge for extended periods. Charging to 80-85% and unplugging early is better for long-term battery health than charging to 100% overnight.

    When the battery degrades significantly, most Android phones can have the battery replaced. Manufacturer service centers, Best Buy Geek Squad, and local phone repair shops can typically do it for $30-80 depending on the phone model.
