The answer is as follows: If the back cover of the mobile phone battery cannot be removed, it cannot be directly connected to the universal charger for charging. In this case, you can consider using some other methods to charge your phone battery:
1. Use a wireless charger: If your phone supports wireless charging, you can use a wireless charger to charge your phone. Simply connect the wireless charger to the universal charger, and then place the phone on the wireless charger.
2. Use a charging cable to connect to the bottom of the phone: Although the back cover of the battery of some mobile phones cannot be removed, there is still a charging port at the bottom. You can use the charging cable to connect the phone to the universal charger and charge the phone through the charging cable.
3. Use a mobile power supply: If you have a mobile power supply, you can connect the mobile power supply to the universal charger and use the mobile power to charge the phone. This bypasses the restrictions on the back of the phone's battery.
Please note that you should pay attention to safety when using any charging method to avoid overcharging or charging for a long time, so as not to cause damage to the phone battery. It is best to use original or certified charging equipment to ensure the safety and effectiveness of charging.
