Does anybody have a ideal what is using my GPS. If I have it turned on and bring up my lock screen, before I even unlock it, it is searching for GPS. The latest thing using the GPS was Google play services but I have the location history setting turned off. Thanks in advance for any help

Hey All,
Hopefully you guys can answer this questions for me. I've noticed that whenever I load google maps it will never ever lock onto my position it only uses network location UNTIL I load up a software program such as GPS Test. once I turn on GPS test withing 15 Seconds I have a lock. Once I have a lock I can go into Maps and all is well.
So, is there a problem with Google Maps where it wont lock your GPS position until you use GPS Test? Can anyone shed any light on this subject?
It requires more than just 1 sattelite to get your location. On your lbstest
It will say you got these satellites but not location
Longitude and laditude

Thanks for the reply, but you missed my point. In lbstestmode or other gps apps I can get a lock of 9 out of 10 satellites in less than 15 seconds with great signal strength(over 50).
But if I don't use lbs or some other app before starting google maps I never get a lock at all. Why would that be? Any ideas? So now I have to run 1 program(lbs) before running maps. Why won't google maps lock onto satelites?

I noticed the same thing. I have switched to the new jl4 modem and i don't seem to have to launch gps test first. It seemed like it was something to do with maps caching gps data and gps test not caching.

If i leave gps on.... and all the apps i have that may use gps (travel, voucher etc) do not run in the back ground,
except google maps.... will this really drain random battery throughout the day.
The reason I ask this is when using google maps...i see the gps symbol on the top of my phone, but once i back out of it...the symbol disappears, and when i go back into it to resume what i was doing the symbol turns back on and the gps has to find my location all over again.
Hence I come to the conclusion that the gps is not 'always on' when you don't need or (given you don't have any dodgy apps)
Then I could turn off googles location sharing thing, because if I am correct you need that on if you want to use location services without gps?

This is a modern GPS chip, it don't think it uses much battery. I've always GPS on and I've no battery issues. And I agree that it seems that the chip is set to some kind of standby when not in use so turning off the GPS in the settings (or notfication pull down) seems more like a privacy thing than power related.
Thanks for confirming. Will now try leaving gps on and location services off and see what happens. sometimes gps on its own takes a few extra seconds to locate you...might be annoying with certain apps
If you refuse location sharing you will not be able to use WIFI positioning service, but can still use cell tower positioning if your GPS is off. Personally I never use WPS since WIFI use a whole lot of power so I always keep it off. There are situations where it's useful (i.e. inside downtown can't get a GPS signal), so you can decide if you want it or not.
I usually keep my GPS off too, since when I open maps I just want to look at map, I don't need to know my exact location (and use the extra power).
My Galaxy S2 GPS sucks the battery life when I keep it on. My partner keeps his Galaxy S2 GPS on and the icon only comes on when something like Maps loads but immediatly goes away when you you exit Maps. Mine seems to stay on all the time and I can't see any obvious process running all of the time (except Maps). I monitor the battery usage with a tool and GPS is certainly running my battery down far quicker than if I turn it off.
Anyone else experiencing the same?

I have the GPS setting turned on all the time, but my GPS only really turns on when I open an app that uses GPS, like Maps or Facebook. Just like your partner.
I actually want to keep it on all the time... like yours
Can you send me your /etc/gps.conf and /etc/sirfgps.conf ?
I'm not sure if that's what control this behaviour.

I only had the gps.conf, not the sirfgps.conf file. Attached here.
I have to turn on GPS only when I need it for something and turn it off, otherwise it clearly drains my battery, in pretty quick fashion.
I had to rename it gps.txt to upload it.
Keeping GPS on is not draining your battery, because its realy turning on, only on application requests. Battery drain may come from some buggy app, which not close it GPS connection. You can easily see this by your GPS indicator. No indicator - no app using GPS atm - no battery drain, flashing indicator - GPS trying to lock ur position, indicator on - GPS is used and got lock on sattelites.

Is there a way to keep GPS always on, independent of an application request?
I want to control it on/off manually
I leave GPS on all the time. Only works when apps request / need it. No battery life issues for me.

I've had this issue for a while now, but I'm wondering if it's just me or if this is something common.
Every once in a while, my Player (5.0 US) will show the GPS trying to acquire a signal icon, but it won't go to lock. I've been in places where I have good GPS signal normally, and it will stay that way for hours.
To add at my confusion, it sometimes comes up even if the GPS is turned off. In these cases, I've turned on a GPS reporting tool, and it can see that I've got a good connection with several satellites. I turn the GPS officially on, and it gets the lock (thanks to the program). Close the program and the GPS goes dormant again.
The only thing I can remotely think of is Google location services trying to pin point where my wifi is, but that doesn't explain why it can't get a lock.
Anyone else seen this or know what it is?
Hi there,
I have exactly the same problem as you. GPS is turned off but its symbol is flashing in the notification bar. I noticed this problem tomorrow morning wondering why my battery is low although I charged it yesterday afternoon.
Are you using gingerbread?
Sorry for the late reply. Yes, stock setup right now
Hello, everybody!
Please, advice on my problem. After some uptime, my WT19i starts having trouble with GPS. When I turn on some application, e.g. navigation, maps or even GPS status, it asks to activate GPS, and after activation doesn't start to search it. I went through the internet, and found problems, when GPS was locking very long time, but in my case it doesn't locks at all, even GPS icon don't flash in notification bar. GPS status and other kind of apps don't help. GPS starts working normally as soon as I reboot my phone. I'm using CyanogenMod 9.1
Thanks in advance!
For those that have had issues with battery drain like I did, I may have finally found the solution.
After much research and reading many threads I found that the culprit was google play services. Specifically it was Google (I believe on Now) always trying to figure out location.
It always does a quick wifi check to try and figure out what's what. However due to a bug that has been in the coding since launch of KitKat (hurry up and fix it google) it fails and will just continue to try and try and try.
Solutions I found were to turn off location access on phone or edit Google Play Services Permission, specifically disable stay awake permission.
Turning off location, google now access to location, or both resulted in temporary fixes and I believe google still tried to figure it's location via wifi despite being told not to.
Long story short...if having just wifi location doesn't work.. and having location off doesn't work...
Then why not switch mode to high accuracy in which GPS is left on!
Google uses GPS for location, it works in one try, everyone is happy!
Long story short, if you have KitKat and are experiencing high battery drain with you phone constantly awake when off.
Switch your location settings to High Accuracy. Phone is smart enough to not use GPS when not needed.
It worked for me and it might work for you too!:good:
(Hopefully this fixes it for good)

its working bro......cheers......:good: great ........
So usually I just keep GPS off to save battery. What your saying is to keep GPS on with high accuracy may actually improve battery life over keeping GPS off altogether?

hi all
is there anyone here already try AppOpsXposed? http://forum.xda-developers.com/xposed/modules/xposed-appopsxposed-appops-4-3-t2564865
it's work at My desire 601 kitkat 4.4.2 without root
this apps can disable hidden system location and other thing but not sure work or not but so far my battery getting better now...
I have the same problem but the solution doesn't work.
I think you fixed the problem by charged the phone and not with switch gps (see your graph).
My solution now is only reboot.

I have GPS switched on. it just doesn't keep it running google play services will turn it on as needed instead of trying to get location from wifi and locking up even when told not to.
Different people have had luck with different solutions and this was mine.
Here are my results from today, the first small block of awake is from me Listening to music for about an hour on 4G.
Not sure what the second block is, might have been apps that updated or the bug returning for a couple minutes. (battery was at 45% at time of pic)
Thanks for this! I'm going to have my wife give it a try!
