Does leaving the GPS/Bluetooth on drain the battery?

[hookbill]

Maybe I don't know what I'm doing but I've never found a way to turn GPS on or off. What I mean is when I use the car I press navigation and I see the GPS icon come on but once I navigate away from it the GPS icon disappears. I also don't see any battery use at all for GPS.

What am I missing people? Still got lots to learn it's only been two weeks.

Menu > Settings > Location & security settings > check/uncheck "Use GPS satellites"

OK and mine was turned on. But when I check my batery use, it doesn't show any drain from GPS. Not even 2%.

Thanks after I got there of course I remembered. I'm getting older, I forget things from time to time. :embarrassed:

no embarrassment needed... not uncommon with all the settings on this device to 'forget' where things are... i've done it numerous times

You can also use the Default Power Control Widget where it displays WiFi, Bluetooth, GPS, Sync and Auto-Brightness toggle switches.

As many others have pointed out too, GPS doesn't drain the battery too much, from what I have seen, the GPS receiver only flips on when you wake your phone (Usually an app kicks in to GPS locate you, then checks the GPS once in a while where you are at. Navigation uses it more heavily as it needs to update and navigate people more, but Maps and other apps can use it a little infrequently.

WiFi and Bluetooth, while not connected, will be actively searching for a WiFi access point or a Bluetooth device it should be pairing to, so that would be more battery intensive as it is reaching out for a signal than just passively receiving information.
