If your phone has been draining power faster than usual, it’s probably time to learn how to check battery health of Android. Battery performance naturally degrades over time, but the good news is you can track it easily. In this guide, we’ll show you step-by-step methods to monitor your battery’s condition using both built-in features and reliable apps.
Checking your battery’s health helps you detect early signs of wear and avoid unexpected shutdowns or poor performance. Whether you’re troubleshooting issues or just curious, these methods will keep you informed.
Method 1: Use Built-In Battery Stats (For Most Android Phones)
Many Android devices come with built-in battery diagnostic tools. These options vary depending on the phone brand and Android version. Here’s how to access them:
| Steps | Action |
|---|---|
| 1 | Open Settings on your phone |
| 2 | Tap on Battery or Device care |
| 3 | Select Battery usage |
| 4 | Tap on Battery usage history or More battery settings (depending on your device) |
This method shows you apps draining the battery, screen-on time, and overall usage trends. While it doesn’t show battery health directly, it helps you determine if an app or setting is affecting performance.
Method 2: Dialer Code (For Some Android Phones)
You can access hidden menus using dialer codes, though not all Android brands support this feature.
- Open your phone dialer
- Type
*#*#4636#*#* - A hidden menu will pop up. Tap on Battery information.
Here, you may see your battery’s health status, voltage, and temperature. If your battery health shows as “Good,” you’re in the clear. But if it reads “Poor” or “Unknown,” consider further diagnosis or replacement.
Not all phones support this code, especially newer models. Brands like Samsung and Google have removed or disabled these codes for security.
Method 3: Use AccuBattery App
If you need detailed insights, third-party apps like AccuBattery provide real-time battery health monitoring. It’s highly rated and trusted among Android users.
How to Use AccuBattery:
| Step | Action |
|---|---|
| 1 | Download AccuBattery from the Play Store |
| 2 | Open the app and grant permissions |
| 3 | Use your phone normally for a few charging cycles |
| 4 | Check the Health tab for battery capacity and wear level |
AccuBattery compares your phone’s designed battery capacity with the actual one. For example, if your battery was designed to hold 4000mAh but now holds only 3200mAh, it has degraded by 20%.
Additionally, AccuBattery shows:
- Estimated battery capacity
- Charge/discharge rate
- Charging habits and recommendations
Using such tools regularly can help extend your battery life over time.
Tips to Improve Battery Health
Monitoring your battery is just the first step. Taking care of it daily ensures it lasts longer. Here are quick tips:
| Tip | Why It Helps |
|---|---|
| Don’t overcharge | Keeping the battery at 100% for long periods can wear it out |
| Avoid deep discharges | Try not to let your battery drop below 20% often |
| Use original chargers | Cheap alternatives may damage your battery |
| Avoid high temperatures | Heat accelerates battery degradation |
According to Wikipedia, lithium-ion batteries (which most smartphones use) degrade faster when exposed to high temperatures or poor charging habits.
Why Battery Health Matters
Battery health directly impacts how long your device stays powered and how efficiently it runs. Poor battery health can cause random shutdowns, lag, and overheating. If you notice any of these signs, it’s time to check the battery before assuming the phone is broken.
