Hi awneil, thanks so much for your answer. But I don't know how to properly stop the advertising. Actually when the device is charging, I want to stop the advertising because of the charging current issues and I want to advertise again (normal mode) when the charging is off. I want to stop and start the advertising properly. How can it be done?

Whether it's significant or not will depend on the rest of the system.

So you need to do a profile of the whole system's power consumption - then you'll see how much is due to advertising and, thus, whether that's a significant contribution.

Note that you can reduce power consumption due to advertising by reducing the Advertising Interval - at the cost of "connectability" ...
