In some cases, battery drain can be attributed to hardware
issues, such as an aging battery that can no longer hold a charge
effectively.

Check Battery Health

Use a Battery Health App: Download a battery health monitoring app from the Google Play Store (e.g., AccuBattery, GSam Battery Monitor).

Analyze Battery Health: Open the app and review the battery health report. Look for signs of wear, such as a reduced capacity or abnormal discharge rates.

Inspect the Battery for Physical Damage

Remove the Back Cover (if applicable): If your device has a removable back cover, take it off to inspect the battery.

Check for Swelling or Damage: Look for any signs of swelling, leakage, or physical damage to the battery. A swollen battery can be dangerous and should be replaced immediately.

Test with Another Battery (if possible)

Borrow a Compatible Battery: If your device has a removable battery, try using a different, compatible battery to see if the problem persists.

Monitor Battery Performance: Observe whether the new battery improves battery life. If it does, your original battery may be faulty.

Check Charging Port and Cable

Inspect the Charging Port: Look for dust, lint, or debris in the charging port that may prevent proper charging.

Test with Different Cables/Chargers: Use different charging cables and adapters to ensure that the issue isn’t related to faulty charging equipment.

Perform a Factory Reset

Backup Data: Before performing a factory reset, back up important data, as this process will erase all data on your device.

Go to Settings: Open the Settings app and navigate to “System” > “Reset options.”

Select Factory Data Reset: Choose “Factory data reset” and follow the prompts to reset your device to its original settings.

Visit a Service Center

Contact Manufacturer or Authorized Service Center: If you suspect a hardware issue and the above steps do not resolve the problem, contact your device manufacturer or visit an authorized service center for further diagnosis.

Request a Professional Evaluation: Technicians can perform hardware diagnostics to identify any underlying issues affecting battery performance.

Consider Battery Replacement

Replace Faulty Battery: If the battery is determined to be faulty, consider replacing it with a new, genuine battery from the manufacturer or an authorized dealer.

Follow Proper Replacement Procedures: If you’re comfortable, you can replace the battery yourself; otherwise, have a professional do it.

Monitor Battery Performance After Repairs

Keep an Eye on Battery Usage: After addressing any hardware issues, monitor your battery performance over the next few days.

Check Battery Usage Statistics: Go to Settings > Battery > Battery Usage to see if there’s an improvement in battery life.

By following these steps, you can identify and address potential hardware issues that may be causing battery drain on your Android device.
