Why can't my mobile phone battery be charged?

Smartphones have gradually become one of the indispensable products in people's daily lives, given the relatively important role they play. However, one critical drawback lies in battery consumption. Today, we’ll discuss a common issue and malfunction—specifically, when a phone shows that it's charging but, instead of gaining power, it continues to discharge. This information holds value for those who are interested in understanding or have encountered similar situations.

1. Why Does the Phone Show It's Charging but Actually Discharging?

If your phone indicates that it's charging but the battery level keeps dropping instead of increasing, you’ll need to check where the problem lies.

1. Charger or Cable Issue:

- Check whether the charging cable and adapter are functioning properly. Try using a different cable or charger to rule out a faulty power source.

2. Battery Connection Problem:

- Inspect whether the battery is correctly connected to the phone. Sometimes, when replacing the battery, the connector may not be properly seated or may have loosened, preventing charging.

3. Poor Battery Quality:

- If the replacement battery is of low quality, it may fail to charge or charge very slowly. Try using an Original Equipment Manufacturer (OEM)-approved battery or a compatible branded one.

4. Faulty Charging Management Chip:

- The charging management chip inside the phone may malfunction, preventing normal charging. In such cases, professional repair or replacement is required.

2. Common Reasons Why a Phone Won’t Charge

1. System Glitch:

- A software issue may cause incorrect battery level display. The easiest solution is to restart the phone, which refreshes the system and usually restores normal battery readings.

2. Faulty Charger:

- A defective charger is one of the main reasons a phone won’t charge. To check if the charger is the problem, simply try a different one. If the phone charges normally, the original charger is faulty.
- Solution: Purchase a new charger.

3. Poor Connection Between Charger and Phone:

- This is also a common issue, often caused by improper insertion of the charger. The solution is simple—replug the charger or try different ports.

4. Battery Failure:

- Phone battery issues are rare but possible. If replacing the battery, always choose a reliable third-party brand with warranty coverage.
