When an extended battery for X10 mini (Not pro), in the back cover?
All we know the main fault of the X10 mini is the small battery
We know the OEM has no easy replacement
But it would be easy for manufacturers to make a back cover with extended battery incorpored and conected to the existing microUSB connector (and duplicating the conector for it beein usable)
I have writen to mugen to do it
all interested people please ask them too (http://www.mugen-power-batteries.com/contacts
And to other manufacturers you know
