How to tell what app is using GPS?

I often see the GPS satellite symbol showing activity like some app is using my GPS when I dont have a GPS or navigation related app open. How can I tell what active process is using GPS at a given moment?
Thanks

Why don't you just disable it?

Because I want GPS to be ready when I do open a nav app. And I am curious if there's a way to tell what is using it.
Go to menu-system apps-running...
List all you have running when you see that gps symbol. My guess is that you may be signed into google latitude.
If it is latitude, go to google maps, settings, and somewhere in there is an option to sign out of latitude.
Its not latitude. Google sets GPS to sleep when apps are running in the background. Third party developers aren't as good as Google.
Anyone have a real answer and not a guess?
Searched very long for a solution and it was quite hard to find the solution working without root, so I'll post it here:
Get the app "GSAM Battery Monitor" from Google Play, on GSAM's start screen select "Application Usage",
then on top of the screen select to view the used GPS time.
Well, this doesn't show which app is using GPS right now but you can see how much time each app actually activated GPS since the last battery charge, so this is very helpful to determine the apps using GPS in the background.
Hi
Even if your gps is turned on, it dosen't necessarily means that gps is being used. Use Spare Parts app from play store and it'll show you what all apps used gps since you last plugged in your phone charger. And yes, don't use this app while your phone is being charged...otherwise the readings gets resetted.
Also, the android os uses gps continually, like the camera app, gallery app etc.

[Q]How do you limit Google maps wake-ups?

I'm looking for someway to lessen/ prevent Maps location sync service from waking up my phone every few seconds. I've tried turning off the location update with in the app and a good deal if the settings in Google now. Its killed a third of my battery according to better battery stats. Any suggestions would be appreciated.
I'm on the ns4g sprint ota jb with thalamus' latest with idle 2 disabled.

Disable Location service in Latitude
Disable location in phone settings, both GPS + celltower
Using an app such as Autostarts or Gemini app manager, disable all starting events
That fixed it for me, forever. Never get any wake up anymore.
I'll try the Gemini and let you know

[Q] Google Search battery drain

Last night I left the phone on with 40% of battery. On waking I found it off, because of battery drain by Google Search.
I state that I have everything turned off, Google Now is not present, perhaps because I turned off the geolocation.
It happened to someone? :silly:
To fix Google search go to Google Search app information and clear the data this also clears your launcher data so you will have to re setup your launcher shortcut and widget's.

[Q] Active Sensors

Is there any way to find out which sensors of device is active?
It's important when a buggy app active a sensor for all the time and battery going to die so fast

Depending upon the app, required sensors get activated. For example, Google Maps uses Read Location permission that uses sensors like magnetic gyroscope, accelerometer sensors including GPS locating sensors. Check App Info to get a rough idea. Use CPU-Z to find the sensors which are available in your phone.
In Playstore there's app to check quick sensors your device has , which active, and which broken /not working.... Andro-sensor being the one I install on all my devices, and droidsensor. Both work great... I like Andro-sensor for the sensor specific data, but droidsensor had other tabs, that have useful info also...

Gps quick setting?

I'm not setting a gps quick setting option. Am I missing something or it doesn't exist? Closest one I found was location, but that turned off the whole location
Sent from my HTC U11 using Tapatalk
It does exists. I don't understand well your question.
If you press and hold position toggle you can access Position settings.
Yes the Location toggle is the GPS toggle. It will turn the GPS on and off.

In location settings you have 3 modes. High Accuracy, Battery Saving, Device Only. Only High Accuracy is technically considered GPS since it uses the GPS module on the phone. I want to be able to flip from High Accuracy to Battery Saving because of applications like weather or yelp that require your location through mobile data. If I turn off all location services which is what that toggle does, it turns off everything. I guess I'll just have to go through the menu for this.

Yeah Both The High Accuracy and Device are True GPS modes, while battery saving mode is only using wifi or mobile data(not actually using True GPS). Like the above user said only way to do what you want is long press the quick settings Location and choose from there.
Found what I was looking for by downloading the HTC gps widget https://www.apkmirror.com/apk/htc-c.../gps-widget-7-50-636098-android-apk-download/

Installed that too on my device, but doesn't works...it only reads status, does not toggle gos on or off...
It doesn't have a GPS icon. It only has a location icon. If you go into location in settings you can turn it off completely by the toggle at the top right..
