Not much help in knowing how long its takes to charge, but I noticed this.
When I first got the little SE, the display used to change from ‘Charging’ to ‘Charged’. That was way back in January.
I wasn’t using it for few months; then couple of days ago I tried charging it. But even after three hours, the display won’t change from ‘Charging’ to ‘Charged’. In the Windows Explorer, right clicking on the Sansa icon and selecting ‘properties’ show the charge as a % figure. But it didn’t change. Stuck at 96% in my case. Then I took out the SE from the PC and plugged it back in again after 10 seconds. Then the ‘properties’ showed 100%. But the display continued to show ‘Charging’ and not ‘Charged’ as it should at 100%
May be ‘Charged’ will appear on the display only with new batteries and not after sometime when the max capacity drop (as is normal with batteries).
Have you tried taking it out and plugging back again as I did? ?
