    I used Navigon for about 1.5 hours straight. During this time I received no phone calls and probably 10 push notifications. My battery drained down 47%!!!!

    Just curious what others are experiencing...

    This sounds about right for most GPS apps. You have to remember that you probably have your screen on, the app is running (CPU!), you have your cellular data chips going as well as the GPS chip maintaining a connection with the satellite and reporting your location - that is a HUGE drain on your battery.

    I personally have an iPhone/iPod adapter that's part of my stereo in my car, so it's always charging - but dropping 50% or more over the course of an hour sounds very accurate when using a GPS app (in fact, using Google Maps with Location Services/GPS on during that same time span with the screen always on will yield similar results).

    It would suck if you used your GPS to get somewhere and when you got there you had to make a call but had a dead phone - basically, the moral of the story is: invest in a car charger!

    Sounds right since you aren't charging it.

    I have a Pioneer stereo with a USB plug that I hook up my iPhone to. I notice that it can't keep up with the power needed by my iPhone when Navigon is running. For short trips the battery percentage stays even, but if I'm using it for an hour or longer, I notice that the battery percentage drops even though it's plugged in the whole time. Do you see this on yours?

    A cigarette lighter charger is able to charge my phone fully under the same circumstances though.

    Nothing, I have a car dock setup. When I leave the car, the battery remains at 100%. Thats with Navigon, Push notifications, and iPod playing :D

    If you plan to use your iPhone as any type of GPS, get a car adapter, they are only $15!

    on a related note

    and not to hijack the thread, is there a particular charger that is recommended for use with the navigon/iphone combo? i have the griffin powerjolt, and if i am running only navigon (as opposed to navigon/iphone combo) my screen goes dark and eventually turns off, forcing me to slide to unlock. I read the navigon manual and they said a 'small number' of users are experiencing this problem, and they suggest users invest only in 'apple certified' chargers..not sure what that means..since to my knowledge apple does not manufacture a car charger.

    any ideas?

    Is your iPhone's auto-lock set to never?

    I've been using the Power Jolt Duo Universal with my 3GS and also Navigon the past few days and haven't had any issues. The screen has remained on the whole time.

    Also, today while driving to work, I intentionally did not use the car charger and ran Navigon as well as the XM app (both using backgrounder too) for the entire drive.

    Battery went from 100% to 82%.
    Usage: 27 minutes
    Cellular Data: 19.7 MB

    Seems like a big drop, but probably as expected when concurrently running one streaming app plus a GPS app (and checking a few e-mails here and there).

    nope..but just switched it. guess this means that i'll have to be more conscious of manually locking the phone though.

    @ dmk thanks for the recommendation. i'll try the autolock thing first, then go from there.

    thanks!

    When the TomTom cradle is released will we be able to operate the navigation in Airplane Mode?
