I have an HTC Magic running Android 1.6. There are two settings for determining my location: 1. Usage of GPS satellites 2. Usage of wireless networks Do any of them drain additional power when I'm not running any applications that query location information? Some people say yes and recommend turning them off until you need them. Others, like this post, claim that the GPS setting does not use power until an app uses the facility, but doesn't say anything about the wireless network setting. Does anybody know for sure? I'd like to keep it on all the time so I can use apps like 'Where's my Droid'.
