If you have Locale installed it'll EAT your battery. After i uninstalled my battery has improved almost 50%
yea, that will kill your battery, i think its standard for it to check location every 10 min.............. but depending on where you live, letting it triangulate your location based on cell towers might be good enough, that what i do.....it can even use wifi spot to help too, if you leave wifi on(i don't)
Turned GPS off and set it to triangulate using cell towers. It was off by about 5 miles. Actually within the work parameter I have set up. I guess I can try it like that and only enable GPS when I use Navigate.
