Hi
I just noticed that if i am using google maps with my Galaxy Nexus if i left the screen go to sleep, after turn it on again the gps signal is lost and it will do again the process of getting a gps signal,
Is that normal
yes unless you are using the navigation app. its to save the battery from people who would "omg maps is using all my battery, how do i stop it?" lol

I've been trying to troubleshoot my battery drain rate and I found the problem.
When I turn off the GPS, and leave the wifi and bluetooth on, I get tremendous battery life/
What could be causing the GPS to drain the battery?
Do you ahve any programs running in the background that use gps? such as latitude, or that google one that maps your location? If so, gps kills batteries, because it constantly resyncs with the satelites... I believe the sense weather app also does periodic polling to pinpoint your location for weather.
If you dont need GPS exact location tracking, dont leave gps turned on, and turn it on when you need it.
My GPS is always on. It doesn't really hurt the battery life unless you are using with an application that uses the location service. My weather widget is set to refresh every hour and it's not impacting the battery.
I would look at your running programs and figure out which one is using the GPS. If you have the sensorly 4g map viewer, I found that to be a battery hog.
My money is on Latitude, that's been implicated in a lot of these situations. GPS always on is hardly a battery drain unless something is actually using the receiver. If you don't see the GPS icon in the notification bar, it's not GPS-ing.

Interesting tip. I had not noticed it. Thanks.

I have my GPS on all the time and I regularly go over 13 hours without recharging; this is before SetCPU and underclocking.
I have my GPS enabled. Half of the time I'm using my phone, everything is good, everything works fine. But during the other half of the times, the GPS is constantly on the notification bar. I try restarting my phone, still up there in the notification bar with a 'solid' gps icon which says "Location set by GPS"... I can even turn the GPS off, and then on again, and it still doesn't fix the issue. As i turn on my "Maps" app for the first time, my location is already "accurate to 3 meters" before it even loads the map graphics... How do i figure out which app is causing this, and how do i stop this? it's irritating. I have to constantly check my phone to make sure the GPS isn't active and draining my battery. And please, don't say "Just turn off the GPS". Android is designed to work with the GPS enabled. Even if the GPS is toggled "on", it shouldn't be using it unless it needs it, therefore using zero battery. (Just like wifi is supposed to). thanks.
I have the same issue and it seems like it's Maps that's constantly trying to turn on GPS. Once I have GPS off, my battery life is a lot better. Tried uninstall Maps, clear data, re-install...but the issue is still there but not all the time...very annoyed.
Another reason might be an app that is using gps in the background. Facebook, twitter, and other apps might be the problem?

If you have your google search settings on to make local search better, then the GPS will be on.
Facebook, Maps are all GPS hogs.
Just turn it off and on when you need it, the GPS on the S3 locks in seconds anyway, so its not a problem.
In my quest to see why my battery drains so much during idle (3-4%/hour), using GSam Battery Monitor, I find Maps wakes the phone constantly.
I have 'location reporting' from within maps turned off, and location history turned off, latitude location sharing is turned off also.
I do have Google's Location Service turned on so I can use Google Now, and also have GPS satellites and Location & Google Search checked. But I don't see why Location Service would make Maps wake my phone so often (pretty much 1x every minute)
Is this normal? Or is something not right?
P.S. Yes, I know it "only" drained 2% since I unplugged it 1.2 hours ago but it's the first time this has ever happened and as soon as I took the snapshots, it dropped to 97% right away.
I have lots of wakes from Maps too. Likely because you're using Google Location Services and are using Google Now, which needs to know your location.
It is normal. when you check it off try to find it in your running processes, you won't find it.
It stopped doing that to me when I turned off location tracking in Latitude settings in Google Maps.

Yes this is the answer
Go in Maps ->Settings->Position settings and disable background update position

This is my map - settings - location settings screenshot. everything is disabled already.
Eddie1506: where do I change settings in Latitude?
Automaddux: you mean I have to turn off Google Location Service (and in effect Google Now)?
Thanks everyone!
Your not the only one buddy... I just witnessed this right now. Went to sleep to a pretty good charged battery and wake up to about a 35% battery ..

I always have. Even on my E4GT..and have had no problems with deep sleep. But now the phone won't sleep at all.

I leave GPS off unless I need it. That stopped the wake locks for me.
I was referring to those settings on your screenshot. When I turned off everything there, it stopped waking up the device.
But, those settings work for me since I don't use Latitude and Google Now is not usable here in Croatia anyhow.
Sorry
I've had 310 in three hours. Frustrating.

so it's google location services that causes the extreme amount of wakes. so I have to make a decision, whether to enable Location Services and Google Now or live without it. In the end, it seems like the battery life doesn't suffer that much, so I think I'll keep it on...
I keep my Google now turned off because I'm all about battery life. But other people may have different thoughts

Recently the GPS crosshairs icon flashes on my status bar like every 5 seconds then flips off...on and off, on and off all day. I know the simple fix would to be just to turn off gps, but again this just started happening recently. I always left my gps on all the time and the crosshairs icon would only flash when an app was using it, like in google maps or navigation. So I'm assuming it's an app that's using my gps in the background somewhere. How can I figure out what is using it?
Also, I've always kept my screen on the brightest setting with no problem regarding battery life. But I just looked in Settings>Battery and it shows that the screen is responsible for 80% of the battery, with no mention of gps. So, any ideas about what's going on with my battery?
Better battery stats will help you find what's causing the issue. Its a paid app on the play store, look for the picture of a battery and plus sign.

You can find BBB here for free for XDA users.
My suggestion is to look at your apps and see what has Location or GPS permissions (ie. Facebook/G+/4Square, Maps, old Latitude-type settings, anything the "checks you in",...).
It is an app that is broadcasting your position and initiating your GPS to trigger. Find the app and fix the problem.
Is anyone having any issue using non Google maps/nav for extended periods of journey. I'm talking for periods >3 hours to say the very least.
I noticed that only Google maps/nav keeps GPS hooked on for hours.
Any other apps I use like nav maps, waze, etc, after like 30 mins (anywhere between 30-180 mins), it just knocks off GPS. The only way to get it back again is restarting phone.
