I just drove for 10km and half of my phone battery is drained. Isn't it Awkward. How can anyone use it for long drives?
But can i know how much does using GPS drain battery? Tell me in terms of time or km and also the type of system you use(smartphone/gps system).
 
That is why you keep the phone on charge while using it as a GPS Navigation Device.
Even then the battery would barely get charged more. It sort of balances out.

Well GPS is rather dependent on your mobile net connection (3G/wifi). If they suck, your GPS will also suck.
if its agps aka assisted gps. else you should be fine. gps can at times go foobar. if its unable to send sync packets. ermmmmmm trouble :-D

gps is no where related to mobile network. GPS provides latlog which can be plotted on world map. So it depends if you have maps offline then no data is needed if you dont then only data is needed to view map. Still GPS will do its job.
 
anyone tried opensteetmaps?

agps derives its concept from gps, but it uses the MBTS (mobile base tower stations) to triangulate position. thereby saving power of directly hooking up with the sattelite, and then it syncs with the gps sattelite.

In assisted GPS it is. If there is signal fragmentation etc. then locking a signal purely on GPS can take a long time, stretching in minutes. But if its assisted by the network (either MSB or MSA), the lock will almost always be much quicker. Depends on the GPS hardware, some phones have pretty crappy antennas.
 
It is terribly expensive. I bought an Onda GPS device with a 7" screen and Windows CE 6.5 for 2k. (it was a special sale, but even the regular price was ~4-5k I think)
