GPS is constantly "ON"

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.

Why does GPS have to reacquire when switching from one GPS app to another?

Jellybean 4.1.1 & 4.1.2 CM ROM
With GPS turned on, switching from one GPS app to another it takes about 20 seconds for the app to relocate itsself. The GPS has to go thru the entire reacquire sequence.
It seems GPS (even if its turned on in settings) really only gets turned on and off when an app requests it forcing it to reacquire.
IMO the GPS should be turned on all the time if its ON in the settings.
Whats the point of the on switch if its not really on? If thats the case eliminate it. The app can handle GPS location ON OFF

That's crazy talk, do you have any idea what leaving GPS on all the time would do to battery life?

I leave mine on all the time. Of course I know which apps use it and I set them up accordingly

No, you have it enabled all the time. I do too, but it's only on when your apps are using it. You seem to understand that, but that's not what the OP is talking about.

I agree. I don't like that when you find a place in Google Maps and then Navigate to it, the GPS has to reacquire. There should just be a 10-20 second delay between closing a GPS app and the GPS actually turning off. Something like that.

Doesn't even need to keep it on. If it knows the last good fix was only 5 seconds old then it should use that as a pretty good start for your current location.

Completely agree open up maps, to look for something forgot the name go to google now... and waiting... just leave it on for 10 damn seconds i can live with 10 minutes less battery life

Actually in the previous version of Maps I was pleasantly surprised to notice that the hand-off from maps to navigation did not release the GPS lock.
I am not sure if they changed it back but my point being - hand-off from app to app can clearly be done more intelligently but again in the case of Maps we know that Navigation and Maps are the same app essentially so may be it was easier to do it.

The app already does handle turning GPS location on and off, that's not what the GPS permission toggle is for.

[SOLVED] Wi-Fi won't turn off in sleep [post-JB update]: how to diagnose?

SOLVED: See this follow-up post; it's one of those 7 things!
Hi! After updating to LK3 (the stock 4.1.1 JB update), my Wi-Fi stays on even after I put the phone to sleep (contrary to the setting "Keep Wi-Fi on during sleep: never (increases data usage)." See attached pics.
I have disabled thus far:
1) Google Now
2) Location Services "Use wireless networks" and "Location and Google search"
3) Location reporting: now set to "Location manually selected on the map"
4) Latitude location sharing
5) Location history
6) Automatic check-ins
7) Check-in notifications
Basically, everything I could find related to location. But, alas, that battery screenshot is after I changed all of those! Wi-Fi isn't on constantly, but it stays on way longer than just when I have the screen on.
What are my options here? How should I diagnose this sucker? I ran BetterBatteryStats, but they said it looked fine with my log (some apps, through the ambiguous "Alarms" partial wakelock, were the largest cause, but only accounted for 3.6% of the time).
I'm pretty sure this is a post-update problem, as before, whenever I unlocked my phone, I got the little notification, "Connected to #SSIDName#" and the Wi-Fi icon would obviously, then, be off for the first few seconds (and when I opened my browser too quickly, I'd get a "Page cannot be displayed" error).
Thanks in advance, I'll take any ideas/thoughts/help/sympathy/antipathy you can offer,

Same problem here. Before the update, it was doubletwist air sync forcing wifi on at all times. That's disabled now, so I have not clue. Hopefully somebody figures it out. Mine isn't even intermittent, it's always on, and I have the same setting as you.

So, I left my phone alone for the night and these programs used Wi-Fi while the screen was off:
Do you have any of the same apps? I'm going to uninstall Google+, Facebook, and GroupMe today and run this again tomorrow. But, looking at pure download amount, it's something on the OS....
If you're interested in doing the same, the app is My Data Manager ( https://play.google.com/store/apps/...e&utm_medium=organic&utm_term=my+data+manager).
Basically, install the app, but do not open it. When you're ready for bed (or any extended period of not using it), open it, and then minimize it (runs in the background). Hit your sleep button immediately (we don't want to capture anything of the phone when the screen is on). Then, when you wake up/need to use it, wake it up, immediately disable Wi-Fi (again, no artifacts from when the phone was awake), take a look at My Data Apps (2nd page), Wi-Fi.
I'll let you know how my second attempt goes.

The only one I have is Facebook, but yeah it definitely looks like the os.

Well! Maybe I should have given it a little while longer, as it seems to be quite a bit better!
It still stays on longer than the screen, but now at least it shuts off once in a while, haha. It was either uninstalling Facebook, gMail, or GroupMe OR disabling one of those earlier settings...it's still not totally fixed, though. I found the Network Counter app which seems to be a little more specific, so we'll see how it goes tonight,
~Ibrahim~

Hmm this is what mine looks like from today. Wifi didn't go off until I did it manually.

Have you disabled the location stuff? Those are what really helped me. I'm off to run the overnight test, with the new app!

i am having the same issues. my wifi since the jelly bean update has been always on.... the wifi bar in battery settings is solid and has never been off.... so frustrating.

Try "Green Power" app.
I use it to disable both wifi and data 20secs after screen off.
There is a Whitelist and a minimum threshold trigger too.
It works PERFECT in ICS.
At bedtime, I get .5% hr battery drain or better.

Awesome, thanks for the info! Exactly, I don't mind Google Now using the Wi-Fi, but then that opens the door for everything to use the Wi-Fi which will kill the battery when I get back to work.
Network Manager didn't work for some reason, so I tried Data Detective, but the stupid app consumed 90% of the Wi-Fi last night!
The only thing I've heard against battery savers is that they force apps to not use the data, and then they keep asking (creating overhead). I wouldn't have believed it out right except it came from the developer of BetterBatteryStats. But your battery loss isn't bad at all (overnight I average 0.4%/hour with the screen off).

I slightly edited my statement. I get .5% hr or better.
Curious...if you average .4%...
- what rom?
- and what is your lowest cpu freq?
- and is that with data and wifi off?

Haha, right, I thought that's what you meant!
I'm on stock AT&T. Everything is stock; CPU Spy tells me 384Mhz. WiFi on, data off.

Why don't you guys disable it in settings? Open Wi-Fi in settings. Click menu button. Click advanced. Turn off Wi-Fi during sleep. Ta-da!

Yeah, that's an alternative...but if I have a setting that's supposed to turn it off when it goes to sleep, I'd like it to do that.

That's right, well said....hence the opening post!

I have the same issue, wi-fi is always on unless I turn it off.

I'm happy. It's one of those location settings in the first post that caused the locks! Let me know if it works for you guys,

[Q] gps always on

Hey guys my friend has the vz HTC one and her GPS is always on. I turned her GPS off and even disabled location services. I cannot figure out what is causing this but it's only giving her 1 hour of screen on time. I get over 4 on my att version no way it can be that different. When u go to power in settings and click on the graph it shows a solid blue bar for GPS on. Has anyone else experienced this, and more importantly does anyone know how to fix this? Thanks in advance.

Hmm, that doesn't seem normal. I leave both GPS and location services on all the time and my graph barely shows GPS usage.
This happens even when GPS is manually turned off? Is she running stock?

Yea I know it makes no sense....I do the same GPS is never on for me unless using maps.
Yes she is completely stock. I'm curious if either a wipe is necessary, which she is against or maybe a defective unit.

Factory reset really is a pain in the a** but most of the problems I've ever had with Android have been solved with a reset.

Update.....I disabled Verizon location services wiped cache and data re enabled it didn't see her for a couple days and now it's working properly even with GPS on all the time. Not sure if that's what fixed it but it's the only thing I did, and she wouldnt have done anything.

When I first bought the phone, I turned on 4g, then turned it off..
but the 4g icon would stay in the status bar.
I was already at the VZW store for another reason so I went to show a rep, and of coarse, the icon goes away.
bahhh
hope to hear all is well with this!

GPS/Location lost when screen is off??

Hi!
I used to have no problems with this situation on any of my previous phones:
In apps that uses gps, like runkeeper, i get very fast gps lock.. but, then, once I disconnect the screen, the "location" seems to be turned off.. The gps track stops counting. When I turn the screen on again to check what is happening, the phone instantly gets gps lock and registers that new spot. Basically what happens is that I will get a track but, instead of having the full track, I only get "straight" lines between the points the gps locked when i turner the screen on to check what was going on..
I have the location in high accuracy..
Any ideas?
Thanks!

I have the Impression there is a different location provider for the new chipset. When i am at places without any gps signals (for example a tunnel) the reported location is moving with the same speed and direction i had before coming into the tunnel. There also a change in my Google location history. When the screen is off it looks like the location is provided by phone cell only. The reported location is more than 300m away from my real location. I have not seen this in the same locations with my older phones. (Edit: All with Oyxgen OS 3.1.2)

I have the same issue as op on 3.1.2, not rooted.

I have this stupid thing also, stupid phone,

The gps loses the fix right after you leave the app that uses it. It doesn't work in the background, I'm gonna have to return my phone sadly.

So does this happen with the newer firmware? Can you put it in the background with the screen on and it run? It seems like a software issue more so than hardware, maybe I'm wrong but who knows..
Sent from my SM-G935T using Tapatalk

obviously a software issue, but they won't fix it since nobody talks about it. If you switch to another app that doesn't use GPS or turn off the screen the phone loses the fix right away.

Still happens with Oxygen OS 3.2.0

Can you give a try launching a nav session in google map. On my lg G2, when I get a fix in google map then turn the screen off, I will loose my fix. But if I launch a turn by turn nav session I will keep my gps fix even if I turn the screen off.

Could this be related to doze hibernating Maps or whatever app /?

Yes. This is likely related to the aggressive Doze mode that has plagued users in receiving notifications. Try disabling Doze by following the instructions in the link below and try GPS again. If it works, then Doze is the cause.

Turn off power saving mode for using GPS while turn off screen
I have used Strava and it can not be received GPS signal when screen off. Then I turned off power saving mode and it was OK.

And this is why I make my rom that disables doze all together. It kills battery more then it saves.
