Status light indicator lights when initially placed on a charging pad and goes off shortly after.

The indicator on the wireless charging case lit up initially upon placing on charging mat.

After a few seconds it the indicator light goes off.

From what i read, indicator light should always indicate the status.

How do i know that it is still charging.

There have been an instance when i place it on a 5Watt qi charger and indicator lights up and goes off 2-3secs.

I came to check on the battery an hour later and the battery level remains the same.

The same behaviour is seen on the status indicator of other qi chargers of 10Watts and it continue to charge when the status indicator goes off after a few seconds.
