Default [R0] Battery capacity in mAh?

Hi all! I was doing some experiments measuring current consumption(draw) of the device in various contexts (DNse, battery charging...).

Prior to other measurements...What's the battery capacity in mAh?
I want to see how accurate are the samsung's playing duration statements and to see how much energy does really the standby mode use.

Without the battery information is a bit hard, tough because I don't want to open the device for now and the only source is the usb cable
And we don't have yet any rockbox or modded firmware to run a "current-voltage meter" during device use.

Thanks in advance

EDIT: I'm assuming that when the battery is full, the entire current is taken from the usb

The results are interesting because setting the volume at 6 instead of 10 with dnse on should increase the battery life about 15-20 % (2 milliamps less)
The backlight drains like 6 milliamps: this indicate that if it is on at level 1, the battery will last one half
9 milliamps when device is on with no playing stuff
