Good article. Though it seems better to turn tge phone off after reading your suggestion

[ireeb]

Despite following all troubleshooting steps, the device continues to experience significant battery drain, particularly with the One UI home screen. A factory reset is the only remaining option. However, backup attempts via Samsung Cloud have failed, resulting in an unresponsive loading loop. A screenshot illustrating this issue is attached. Note that a stable Wi-Fi connection is being used.
