So i left the apps running "at will" all day with little phone use to see if the apps would kill the phone.... they didn't. Doing other things may drain the battery like, playing with the phone, screen light, GPS, Bluetooth, and maps, but the apps themselves didn't seem to drain the battery to point where we have to obsess about them running in the background. Thanks
Took phone of charge, full night charge. 7am this morning. Went to work had the phone in my pocket, must have somehow how started the sat nav, was in my twice weekly morning meeting when the phone shouts out, "gps signal lost ", knew it had started the nav some how. Anyway to save time i just clicked the back button to get away from the screen thinking it was off. Wrong, by luchtime phone was totaly dead wouldnt even start back up. So yes gps is heavy on the battery life.
Good info thanks!
Ok this the kinda thing people will argue about on crackberry. I have to say once again I dissagree. True I know nothing about how this works besides what was explained in this thread. But what I have actually experienced is different. My phone will slow to a halt! The only thing that fixes it is to restart the phone or use appkiller. Then my phone goes back to being super snappy....
Good to know, that's one thig I currently hate about my BB.
Having an active GPS connection is heavy on battery life. I leave GPS and WiFi enabled and still can let the phone run for 7 hours with only a 30% drop in battery power. If I start up an app that actually uses the GPS continuously, the battery drains much faster, but merely having GPS enabled in the phone's settings will not kill the battery; you have to have a running application that actually makes use of GPS for the battery to drain.
I know that you're talking about potential battery use from a GPS app running in the background, and I agree with you on that, but I did want to point out that just having the GPS option enabled in the phone's settings won't drain the battery; there has to be an app using it.
When using the web, IIRC the google main page will ping for location each session, but I believe it can get that from cell towers too (I may very well be wrong on this, someone correct me if I am). I haven't noticed this using any appreciable amount of battery though.
My phone settings:
- Exchange active-synch (push) enabled
- Google calendar widget
- The Weather Channel widget (set to "my location")
- WiFi, GPS, and Synch enabled
- Screen brightness off (the lowest setting, the one below "auto")
- Battery Widget (just so I don't have to go into settings to get a quick percentage readout)
- Screen time-out at 1 minute
And, of course, whatever main app I am running at the time. I'm pretty anal about shutting an app down when I'm done with it rather than just going back to the home screen.
One last thing to check is to make sure that you have updated your phone's PRL. This ensures that it has the latest cell tower preferences which can make a big difference in power consumption. Sometimes an out-dated PRL can have your phone trying to use an old tower and having to transmit at higher power and ping more often as a result.
To update the PRL, dial *228 and choose option 2.
