Charging Connected disconnected loop

[Redines]

Hello everyone,

I am facing a charging issue with my Samsung Galaxy A16. Whenever I connect the charger, the phone keeps showing “connected” and “disconnected” repeatedly in a loop, so the phone does not charge properly.

Important details:

- I am using the original Samsung charger, cable, and adapter.

- The charger works perfectly with other phones and supports Super Fast Charging (25W) on them.

- My phone is still under warranty, but unfortunately there is no Samsung service center in my district.

This problem started after updating to One UI 7. Before that update, the phone was charging normally without any issues. After the update, the problem began. Since then, several updates have come, including major updates like One UI 8, but the issue has still not been fixed.

Now the situation has become even worse. Sometimes when I plug in the charger, the connect–disconnect loop continues for hours, and the phone barely charges.

One important observation:

- If I switch off the phone and charge it, the phone charges normally without any issue.

Because of this, it seems like the charger, cable, and charging port are not faulty, and the issue might be related to software or the update.

If anyone has faced a similar issue or knows a solution, please help. I would really appreciate any guidance.

Thank you.

Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issue.

Kindly check the power socket functionality with a different device or try to charge the device in a different power socket.

1. Check connectivity: Please check whether the charger cable and adapter are fixed well. Remove the charging cable and reconnect with the mobile phone properly.

2. Check charger functionality: If different devices charge with the same charger. It seems your charger is functioning, before getting into the mobile-related troubleshooting, I would like to know whether you are using a Samsung-approved charger.
Note: We recommend our customers use only Samsung-approved chargers, as 3rd party chargers with different output ratings may cause errors in the device.

If the device charges with a different charger: It seems there is an issue with your charger, kindly check the physical condition of your charger for any damage.

3. Update device software (If available): Settings > Software update > Download and install > Checking for software update > Software update available > Download > Downloading updates > Install now.

4. You can reset your device by following the steps.
