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.

Guys,
Lot of talk regarding battery life/ standalone/ accuracy of gear S apps for running.
Used both Nike and S Health- to me both were standalone.
Few bullets
1) some stated that even with GPS on and locked that s health still uses pedometer for distance? (is this true?)
2) I'm still confused if I need gear network AND/OR mobile network on/off - does this affect battery life- if I leave OFF all networks...will my run sync once I turn mobile network or Bt with phone on?
3) any way to get splits read to you (cannot believe this is missing)
4) I don't think this device will get through a marathon unfortunately
Yikes! Just did the car test (run shealth with hand out car) and I can confirm that it doesn't use gps for anything other than map. Feel duped
Relies on pedometer I think
Sorry for my blast posts. It is possible that it only records speeds in running range? I shook hands and didn't increase speed. Also noticed a bike option. Perhaps wrong about duped. Lol
Hello Jeffruby,
I've been in contact with Samsung about S-Health on Gear S and they confirmed that they are not measure the distance with the GPS, just the map (Totally insane!)
The Nike+ app is tracking the distance correctly with GPS though. If you have everything turned on (GPS, GSM, Bluetooth), then you would get probably about 4-5h of battery time. My goal is to use it on the next marathon and be able to listen on music for the last 60min of the race but i guess I need to run on 3:30 or something to make this possible
BUT, unfortunally the Nike+ app are missing the most important thing and that's the avg pace for the total run. It just show current pace and I don't really like that since it's changs so often so it's hard to see what speed you are runnig at.
So, yeah, I really hope for an update on either of these running apps ASAP!
HTC, thanks.! What a shame re s health app. How do you think it does distance for biking though if uses pedometer for distance?
The Nike app is close to being good..... I can't see the red on black, while your running you can't read scrolling info and of course the avg pace of run is the gold
Also in Nike app you have to turn on GPS manually, not from the app, if you want to track distance accurately. If you don't it uses accelerometer. With GPS on in general battery life is not good. My longest run was 30K in 2:45 had 18% battery left. Also there is one more strange thing about S health - calorie count maxes out at 1000
OK , so I did another test today - used shealth on bike mode. Stuck arm out car window with GPS on. Kept arm still. It tracked distance completely accurately. This tells me that the s health must indeed use GPS accurately. I think the jog portion only measures speeds in running or walking rates as it did not pass my car test.
The Nike app is a bummer as you can't verify GPS lock before it starts. Also the reasons mentioned prior.
The s health app is easier to read but doesn't show you 1 mile splits on the phone app. This is unacceptable.
Completely agree with the issues mentioned with nike+ Visual gps status before starting, the ability to display the info you want while running, and a always on mode during use would also be handy. Now I have to flick my wrist and wait untill the display goes on. It takes too much time and you're not seeing what's happening before you. A quick glance should be all. Currently i use a gear store app called screen awake for this.
Yeah, i have been logging miles with the Nike ap too. Its not perfect, but it works for me.
I have 79 miles all logged on my Gear S nike ap this year.
Sent from my SAMSUNG-SM-G900A using XDA Free mobile app
Not to mention Nike app wastes battery with hr but doesn't record it.
The S Health app records continuous HR during your run. I'm not sure how the Nike+ app works to record HR data. Is it continuously tracking/recording HR data? Or does it do it intermittently when you activate the display and wait for the information to scroll (on the bottom of the screen) to HR?

In the Nike+ app there's a small round indicator in the upper righthand corner that turns green as soon as there is a GPS lock. Always on mode is great, but it increases battery drain, so I just do the wrist flick.
Jerome, I think he is referring to indicator if Nike gps locked in before you hit start run. No runner wants the first 0.1 mile not to be recorded.

Could it be that the person you talked to had no idea what they were talking about (my usual experience with samsung, sadly)?
I am asking because Gear S tracks distance even with data off. After the run, if i don't see a map, only a track of my steps(*), I think data was off, but I still get the same results. I took mine to Europe with me and still got the distance tracked on my runs, even though the SIM card in it wasn't working. Wouldn't that be a sure indicator that what Sammy told you is incorrect?
(*) when data is on, my tracks are superimposed over a map.

Hello,
I guess I have to answer both Yes and No on that question
I've tried to reinstall, run without data, without simcard, yeah, tons of different test and it's always way off (map is accurate but the distance it shows is totally off). Another poster in this topic also had the same issue but then he told me to test and choose 'cycle' as training mode instead of running, and, when I did that, then S-Health tracks the distance accurate. So, with other words the application have support for tracking distance in that training mode but of some reason it seem to choose to track the distance by counting steps if I choose running/walking as training mode. So, i'm not sure, maybe your device of some reason have this working on all traning modes. I hope so, and, that someone can explain for me hoooooooooooooooooooow to change this
My gear s tracks distance very accurately when I run gps on. However with GPS off using pedometer it overestimated my distance by approx 0.1 per mile. So gps must work. I did discover as mentioned above, that at high speeds need cycle on.
Not sure if this has anything to do with anything, but my Gear S is the US ATT variety.
In my case, I am fairly certain that no maps are used for measuring distance. Maybe I lucked out.
And when I said my distance gets tracked earlier, I meant the tracks you see at the very bottom of the log in S Health, that correctly display where I took turns, looped back, etc. Without data on, there is no actual map behind them, with data on, there usually is (I had a few flukes before.) The pedometer would not know about turns taken, though.
BTW, I had issues getting a GPS lock for a while until I realized that my phone is messed up. Once I started using the Gear S in stand-alone mode, all was good.
I've had my Z5C for about 10 days. I'm relatively happy with it, except for the battery life. Much worse than my old Z1C. Less than 24 hours of battery; my Z1C always got 24+. So, last night I tried the Stamina mode for the first time. Very UNIMPRESSED! I must be missing something.
1. In Stamina mode I still loss 15% of my charge in 7 hours.
2. With Stamina mode on it takes a couple minutes for my Wi-Fi to reconnect once I turn the screen on. Hardly usable.
What am I missing? Are any of you happy with the battery life? Does it improve over time? If you use Stamina mode, what are your settings and what is a typical battery discharge amount over an 8 hour period of non-use? Suggestions?
Thanks.
Im quite pleased with the battery life. 2-3 days with abt 4 hrs screen on time. I have disabled few services and applications from settings. There is a thread about it. Last night battery dropped only about 2%
For starters, disable location and untick "Scanning always available" under Wifi>Advanced Settings. Disable photo analyser service under All apps. Try these out first

Thanks for you reply. Some questions/points:
1. What am I losing if "Location" is off? For instance, GPS, weather?
2. Can you explain what "Scanning always available" does?
3. Couldn't find photo analyser service. Any thoughts?
4. I've removed set of widgets created with Zooper Widget Pro. I've read that it's a battery hog; any opinions?
5. I'm using an old weather app, BeWeather, because I like its widgets. I did notice that under "Location" BeWeather showed high battery use, while the Google apps listed showed low battery use. Any weather apps with widgets suggestions that might have low battery use?
Again, I appreciate your reply.

I might be wrong on some points, if this changed over the years, but...
1) If android/google isn't searching for location constantly, it will remember the last known location. So only your approximate location will be known, and apps that use it more specifically (like google fit, running apps etc.) will be less effective.
2) It means that your phone will connect to Google servers, even when Wifi is off. As far as I know.
3) It should be in your list with all apps. If it's not, I have no clue where else you should look.
5) I use "transparent clock & weather", and I never ask it to update his location constantly. Instead, I use a fixed location. Even when I'm 100km away from here, the weather will still be about the same, so for me that's enough.
Can't you look at the battery usage stats and disable anything that is near the top that you dont need?
I find the normal drain while using it is about the same as even my old phone. However standby is much much better. I used the phone sparingly and it lasted me about 2.5 days. On average, its lasting me about 2 days. On heavy usage days, I only get a day out of it. I havent had it very long so more testing is needed. There was only one instance where it drained really fast. I was in a plane on the ground. It seems that the reception is rather poor so it has to try alot harder to maintain a signal.

I looked at the power management stats. Oddly, the battery usage is:
Screen 34%
Cell standby 8%
Phone idle 6%
Android system 4%
Android OS 4%
Nothing else is listed. Under App Power Consumption it shows "Currently no apps to report". I don't feel that I'm a heavy user; minimal calls; minimal browser use; minimal texts. I have a weather widget with clock on both screens I've set up. The weather is set to update every 30 minutes. I've stopped using a couple widgets, as mentioned above, but I still don't see a significant improvement.
When you say "standby is much much better", are you talking about Stamina mode, or something else?
Thanks again.
Unless you use google maps, location doesn't matter all that much. Also if you need it in any app, you will be prompted to enable it. Once your work is done, you can turn it off again. Location actually does eat a considerable amount of battery.
About "scanning always available". It means that the phone will constantly be looking for wifi even if the wifi is turned off. This causes standby battery drain so it's good to leave it off.
I'm not sure about the widgets though as I haven't used them.
Lastly, photo analyser service should be in Settings>Apps>All Apps. Disable it to improve performance and battery life as reported by many users here and on talk.sonymobile.com
Cheers

Re: item 3. I had already disabled.
Any more suggestions? I turned on Stamina last night; still lost about 2% an hour. At the rate I now see (including using Stamina at night), I might get 36 hours of usage per charge, and I'm not a heavy user. Nowhere near some of the reports I've seen. I've turned off location, turned off weather updates for 6 hours of the night, turned off scanning always available in Wi-Fi, disabled photo analyzer, and removed widgets that seem to be "on" all the time. Additional questions:
1. I noticed that I have "Keep Wi-Fi on during sleep" set to always; is that OK, or do most of you have that off?
2. Are you all using the regular Stamina mode or the Ultra mode?
3. What is your setting for "Queue background data"?
That's it for now. But I expect to have more questions until I see the 2-3 day range you all talk about.
Thanks.

Try another night with Network mode set to gsm only. Just a thought
---------- Post added at 11:07 PM ---------- Previous post was at 10:53 PM ----------
I actually lose 0-1% overnight (in 8 hours on an average) on GSM only. I usually keep it on 2G. So basically my overnight battery drain is negligible. Also, I don't even use Stamina mode

Thanks for your reply. I've set the network to GSM Only. Seems to help a bit, but I'm still getting 2% battery drainage PER HOUR with Stamina ON! during the night. Again, looking at all the suggestions. The only one that I really use and would rather not disable is "Location". All of the apps under location show "Low battery use". I also prefer to have my screen brightness always around 90% (old age ). Can you tell me what widgets you have on your screens? I'm thinking I'll slowly delete each widget, if any of you think that'll help. I can live with 30+ hours of battery, but it's far from what I was expecting after reading the reviews. My Z1C had better battery duration.

I just have the walkman and clock widgets. Also, i switched wifi off before going to sleep or if it is switched on, i turn on stamina. Also, i have all sorts of sync disabled as i sync manually. My battery is nearly as good as that on Z3c (which is pretty amazing). Maybe some app is acting up on your part :/ I have nothing else to suggest man.

Not the weather app. It's set to not update from 11pm to 5am. Tried the location off, no improvement. WiFi was off using Stamina. Something else is going on that uses 2% an hour no matter what.

Aaaand I've run out of ideas. Try gsam batrery monitor from the playstore. Let it run through the night. That should give you an idea of the consuming apps
Thanks for your reply. I turned off my WiFi last night; only a 4% total loss. Tonight I'll try both the WiFi off and stamina, in addition to your battery monitor suggestion. Getting close! ?
Lost just 2% over 7 hours tonight! Stamina on. But I think my problems were all caused by my Bluetooth. I have 2 speakers on either end of my place that were always on. I also had my phone's BT always on. I noticed that at times both speakers showed being connected at the same time. I suspect that BT was constantly connecting and disconnecting as I moved through the apartment. I've turned off the BT on my phone. Battery life much improved. It's been 21 hours since my last charge and I'm still at 58%.
Thanks to all who responded.

Aah finally hahahah
(it happens with other apps too, so it's not Runkeeper itself)
I use Runkeeper to trace my walking. But seems that when the screen is off, it can't get the GPS signal so the measuring (distance, speed) is not working
It's probably something to do with the settings, but couldn't find where.
any advice?
thanks

I get the same problem with MM Tracker if I use a MIUI 8 based rom. I'm currently using the 'Angels and Demons' rom based on MIUI 7 and don't have any problems recording position,speed etc.
HTH.
I suggest to review the power profile... had the same issue. most probably GPS go sleep while screen is off.
Is MIUI battery saver enabled? Try modifying the setting for your app by going to Security > Battery > App battery saver and changing it to off.
I had to do that for Waze so I could still use voice navigation while the screen was off, now it works fine.
It's a stock T-Mobile LG G5. I get around 2-2.5h SOT. Overnight it drops the battery by 8-11%. There are 34 screenshots in the ZIP file below, showing GSAM Battery monitor and BetterBatteryStats data. I've never used BetteryBatteryStats before so if someone could help me identify the culprit I'd greatly appreciate that.
The signal strength is excellent and the always-on display is disabled. The bluetooth and GPS are always enabled. I should mention that last week I put the phone in Airplane mode and the drain stopped, but obviously it's not a solution.
1.) why do you know, that the gsm signal is excellent? Because you can see 5 stripes in the notification bar? That is not real! I can see 5 stripes too, but this at 15 ASU.
But 100% signal is = 30 ASU! So this result can differ even you believe you can see 100 signal quality.
2.) my system is running on 20p. No BT and no Wlan (no NFC) with 8% for 24Std. (150 user apps installed)
3.) wifi and G-Mail polling sucks much battery power too! you should switch it of to compare! or is it real necessary to be on over the night???
4.) what’s about the google fitness app? this app needs power to check the sensors.
5.) Twitter; Google; G-Mail; Fotos are syncing many times! You can see together more then 800 wake ups!
no wonder that this together will suck your battery empty!
i would suggest you to switch off BT and W.Lan over the night! This should spend a lot of battery power too! Same for syncing and background data traffic.
Try to use 3C Battery Monitor app. there you can see the power consumption every 10 min in the night.
read this too! -> https://forum.xda-developers.com/showpost.php?p=74381087&postcount=327
I have 55 ASUs, so the connection is not the problem. Last night it only drained by 1%. I had both Bluetooth and GPS enabled so I don't think they are the problem either. Twitter, Gmail also were enabled and they actually pulled and displayed some notifications, yet the drain was minimal.
What I think sometimes happens is Google app or Play Services goes crazy starts waking up the phone for no reason. Would you agree based on the screenshots? Or could it be some bug in the OS that does this?
