Have had a Note 10.1 stock ROM for about 4 months now, no previous problems charging when switched on or turned off. Use standard out of the box USB and mains charger.
However, the last 3 times or so, if I charge when it is on, but screen turned off, there was a continuous bing, bing, bing every 5 seconds or so. Only way to stop was to switch off the Note.
Charging / recharging was always slow, about 10/12 hours to full charge from about 40% left in the battery.
Anyway, what is happening now is the following. Yesterday for example. 9pm about 66% left in battery, leave it turned on, and charge overnight. Check at 9am and battery is showing 42%. Switch it off, plug in charger again, this afternoon at 5pm battery down to 24%.
Edit.
Forgot to say it upgraded to 4.1.1 today, so was acting up with previous system as well as jelly bean - or whatever it is.
If I use the USB cable and my SG3 power point, it charges but awful slow.
I use a live wallpaper, no apps running, no wifi, not tethered or anything. I have checked running apps and everything using battery and there is nothing unusual, just system stuff, AVG antivirus (free), screen, live wallpaper etc.
Any help appreciated, as I say this seems to have come out of the blue.
When battery is fully charged it works fine, doesn't drain away or anything like that.
Sorry for the long post.
