I’m experiencing a strange charging issue on my Galaxy S24 Ultra that started only after the One UI 7 update.
Whenever my battery level drops below 20%, and I plug in the charger (whether the phone is ON or OFF), the charging process automatically disconnects and reconnects repeatedly a few times before stabilizing. This does not happen above 20%, and I have confirmed this behavior across multiple charging cables and adapters, including the original Samsung ones.
I have already:
Tested with different chargers and cables
Charged with the phone powered off
Updated to the latest firmware available
Cleaned the charging port
Despite all that, the issue consistently occurs only below 20%, suggesting it may be linked to a software or firmware bug introduced in One UI 7.
Please advise if this is a known issue, and if a fix is being planned or available. I’d be happy to provide logs or run diagnostics if needed.
