symbian and...
My N8 has same problem and since the phone can run for several days without charge, I will point at the GPS too... even via the USB. My Toyota socket is rated 10A, so I imagine the juice is sufficient.
I understand there are external bluetooth GPS's are small, more senstive and much more power efficient.
Something about the compromises of mobiles phones I guess, can't be good at everything....!
