It seems like you've encountered an issue with your Pocophone F1 after replacing the screen and battery. Here are some troubleshooting steps you can follow to determine the cause and potentially resolve the problem:
1. Check Battery Connection:
- Ensure that the battery connection is secure. Open up the device and reseat the battery connector to make sure it's properly connected to the motherboard.
2. Perform a Hard Reset:
- Sometimes, a hard reset can help in situations like this. Press and hold the power button and volume up button simultaneously for about 10-15 seconds. This should force a restart of the device.
3. Check for Signs of Life:
- Connect the phone to a charger and see if any indicator lights or vibrations occur. If there are no signs of life, it could indicate a battery or power-related issue.
4. Inspect the Screen Connection:
- Ensure that the screen connection is secure and properly seated on the motherboard. Loose connections can cause display or power issues.
5. Try a Different Charger:
- It's possible that the charger you're using isn't providing sufficient power. Try using a different charger and cable to charge the phone.
6. Check for Physical Damage:
- Carefully inspect the phone for any physical damage or signs of a short circuit. Ensure that no components are damaged during the repair process.
7. Use a Known-Good Battery:
- If you have access to a known-good battery, consider swapping the battery to see if it resolves the issue. This can help determine if the problem lies with the battery itself.
8. Seek Professional Repair:
- If the issue persists after trying the above steps, it's advisable to seek professional repair services or contact the manufacturer's support for further assistance.
Remember to take necessary precautions when working with electronic devices, and if you're unsure about any step, it's best to consult with a professional technician or repair service.
