2. Common causes and solutions
1. Charging interface problem
Phenomenon: When charging, the angle needs to be adjusted repeatedly to connect, or there is no response at all.
Solution: - Use a toothpick or fine needle to clean the dust in the interface (power off is required). - Check whether the interface is loose and send it for repair and replacement (the cost is about 50-150 yuan).
2. Charging accessory failure
Phenomenon: Use other charging cables/heads to charge normally.
Solution: - Replace with original or MFi certified accessories (see table below for reference prices). - Avoid using broken or cheap third-party accessories.
| Accessory type | original price | Affordable third-party alternative |
|---|---|---|
| Type-C line | 149 yuan | 39-89 yuan (Green Alliance/Anke) |
| 20W charging head | 149 yuan | 59-99 yuan |
| wireless charger | 329 yuan | 99-199 yuan |
3. System or software abnormality
Phenomenon: The charging icon is displayed but the battery capacity does not increase, or the charging speed is extremely slow.
Solution: - Restart your phone (to resolve temporary process conflicts). - Update the system to the latest version (fix known charging BUG). - Close background power-consuming applications (such as games and video apps).
4. Battery aging
Phenomenon: The battery health is lower than 80%, and it heats up significantly when charging.
Solution: - Check battery health (Settings - Battery - Battery Health). - Replace the original battery (the official cost is about 200-600 yuan).
3. Preventive measures
1. Clean the charging interface regularly (once a month). 2. Avoid playing high-performance games while charging. 3. Use a cooling bracket (especially important during high temperatures in summer). 4. Turn on the "optimized battery charging" function that comes with your phone.
4. Still need to pay attention
If the above methods are ineffective, the motherboard charging module may be damaged (repair costs are high). It is recommended to contact the official after-sales inspection first. According to the maintenance data of the entire network, motherboard problems account for less than 3%, and most cases can be solved through simple troubleshooting.
