Introduction
Battery performance can degrade over time, leading to shorter usage periods and unexpected shutdowns. Knowing your Android phone’s battery health helps you plan for maintenance or replacement. In this guide, we’ll show you several methods to check battery health accurately.
1. Check Battery Usage in Settings
Why it matters:
Battery usage stats can give a rough idea of how your battery is performing.
Steps:
- Go to Settings > Battery > Battery Usage.
- Review which apps drain power the most.
- Look for signs of abnormal drain or rapid drop.
Tip:
If certain apps are using more battery than expected, consider limiting background activity.
2. Use Manufacturer Diagnostics (Samsung, Xiaomi, etc.)
Why it matters:
Brands like Samsung include built-in diagnostics.
Steps (Samsung):
- Open Samsung Members app.
- Go to Support > Phone diagnostics > Battery status.
- Review the condition report.
Tip:
Other brands may have similar tools under Support or Device Care.
3. Use Dialer Code (if available)
Why it matters:
Some Android devices let you access hidden battery info.
Steps:
- Open the Phone app.
- Dial
*#*#4636#*#*. - Select Battery Information to view health status.
Note:
This may not work on all Android versions or brands.
4. Install a Battery Health App
Why it matters:
Apps like AccuBattery provide detailed health analytics.
Steps:
- Download AccuBattery from the Play Store.
- Use your phone normally for a few days.
