Black - used boxed - may need charging every couple of days 

We say this because we purchase direct from Samsung and rings are put thru a full diagnostics test for all functions. 
Only then to we list for sale - evidence of the test passes are sent before shipping each ring.

However to test how long the battery will last each ring needs to be worn for several days at a time and this is simply not possible - given the quantity we sell.  That is why we ERR on the side of caution and state may need charging every couple of days.
