That’s it, you have successfully performed a soft reset on your OnePlus 7T.

Use the Original charger and USB cable

Always use the original charger and USB cable that comes with the phone out of the box. This is because the phone manufacturer has officially launched this charger for the particular model accordingly to fulfill the compatibility parameters.

If somehow, the original charger and USB cable of your smartphone is not available, then try another compatible and recommended branded fast charging adapter or cable.

Try an alternative Fast charger and USB cable

Continuously using the charger for several years might affect its efficiency and performance and hence it will slow down the charging capability. Therefore, you might face the fast charging not working issue.

In this case, you should go for purchasing a best-recommended alternative fast charger that could be compatible with your smartphone. The same goes for the USB cable, over a period of time, the cable might also get affected due to bending and twisting and hence might become faulty.

Remove the Dirt particles from the charging port

There is also a possibility that your phone port might contain dirt particles inside. These particles might prevent your phone from fast charging. Hence, you need to clean your phone port carefully with some tiny pieces of equipment such as a stick of ear pick.

Clean the port with the help of an ear pick slowly and once you clean it, check whether the fast charging is working on your phone or not.

Enter Safe Mode

Safe mode is one of the best methods in the troubleshooting process. While in safe mode disables all the third-party apps and allows the built apps only.

If the phone is working properly in safe mode, then there could be any third-party app causing this issue.

Try to delete all the recent third-party apps that are the real culprits.
