HI
short question:
how many hours can this device work with gps logging when backlight is off.
I just want to log my location during my holiday trips (8~10 hours per day).
I dont use voice notification or any function else, just purely record gps location every 1/5/10 min.
10 hour? possible?
I use a bit of software called mysporttraining with the gps addon when I go running. I use it in conjunction with audio manager (to listen to tunes) with the screen turned off and go for about an hour at a time, although sometimes up to two.
I've not really taken much notice, but it doesn't seem to particularly eat into battering life, and two hour runs don't seem to eat more than 25% of battery life, although like I say, I don't really pay much attention to the battery level.
I've tested it running OZIexplore with GPS enabled, backlight on minimum (not completely off) and the battery charged to 100%, hoping to use it for logging my position in a day hikes. Well, forget about it. It runs for approx. 4 hours that way. You will get 5 hours top with no backlight at all, or something like that.
Maybe someone here can code some kind of program that would wake the device up every 5..15 minutes, wait up to 1 minute for the GPS to get a stable fix (should be much quicker that a minute with the ephemeris data from just 10 minutes ago, right ?), store the coordinates in some kind of log readable by popular applications and go back to standby. Obviously, there is no need to turn the screen on. This should easily give it a run time of a whole day from a single charge.

what a shame.
gps log for 8 hours would be a real all-around device for hiking.
Maybe I should get another battery and boost up life time to 4*2 hours?
I've not got round to putting mysporttraining back on my pda since I got it back (and I tend to get it back quite a lot), but I will in the next couple of days and will try running it from a full battery to see how long it lasts

Hi folks!
people from another forum said there run.gps (gps tracking for jogging app) works 8 hours . Maybe this is the trick:
"
The perfomance of both my batteries was initially poor (3-5 hours), but they improved by 20-40% after I ran them down a few times to near Zero. "
"Just running Run.gps (and the mobile on standby), with the screen and device locked via Windows (I keep it in my pocket when cycling/motorcycling) a battery will last 7-8 hours"
Not too bad!
I should really get my hands on some IDE + SDK for WM6 and/or Polaris, so i could try coding things like those myself. This really shouldn't be very complicated. Adding yourself to the notification queue should be as easy as calling some API or simply writing to registry. There should be plenty of examples on how get the coordinates out of the GPS data stream. The OZI track formats should be easy enough as well. Would EVC4 be good enough, or do i have to load the VS2005/2008 bloatware to be able to code for WM6 ?

Just had a play with this and it looks to have a lot of features. It's a shame it won't continue to work when you press the standby button.
With Mysport training you can fire it up, set audio manager going and switch the phone onto standby and it still tracks your movement. With run.gps it just stops the application.
Just been out for a run.
55 minutes in total, with audio manager playing an mp3 and my sport training running at the same time, with phone in standby.
90% battery at the start and 78% battery at the end.

great, that's 8 hous with gps+mp3. i am so gonna get one of this!!!
This is the main application you need
http://www.vidaone.com/mst_ppc.htm
Plus you need the GPS module
http://www.vidaone.com/mstgps_ppc.htm
I've been using it for the past 18 months or so. It won't do routefinding, but as a simple tool for logging your activity, speed, calories etc as well as weight and BMI etc it does the job fine.
If you have the desktop bit:
http://www.vidaone.com/vodf_win.htm
You can sync to that and see your route overlaid on google maps or mapmyride.
I've never really fully trusted battery meters on phones etc, I'll stick it on this morning and see how long it lasts until the battery runs flat

there is no routefinding? that's a pity.
I suggest run.gps www.rungps.net.
it's really a nice app.
they make new features based on users' request. e.g. they have made a heart rate logger for this app. shame is, so far there is no bluetootch heart rate monitor yet. as soon as it goes on the market, they will make a online-heart-rate monitoring function.
go and try.
Nope, no routefinding, as it's an app that's designed for logging and reviewing your activities rather than the former. It does me as I never get lost and just need it as an easy way of keeping tabs on whether I'm doing enough exercise.
Sounds like Run.gps is more the thing you are looking for.
Right, time for a retraction, it seems that run.gps will work with the phone in standby. Went out for a run today and it worked just fine with the phone switched into standby and mp3s playing. Battery drain looks comparable to mysport training too.
This kind of begs the question of why it wouldn't work on standby before - I had tested it in the car with the phone on the windscreen mount and when I switched it to standby it lost gps signal. The only other difference other than it being in a car is that the headphones weren't plugged in. I don't get it.
Run gps looks like a great program though
Stranger and stranger.
It *seems* that the GPS module continues to work with the orbit in standby when in the car only if the headphones are plugged in. How odd.
When an mp3 is playing, the phone is NOT on standby. Audio player should be the one that prevents the unit from entering standby in this case, that pretty much explains the GPS working as well while listening to audio, but shutting down without it.
Well... I tried it again this lunchtime as things didn't seem to be making sense. This time round it seemed to work with the headphones unplugged, nothing running apart from run.gps and the phone on standby (that is to say, the button at the top of the phone pressed until the display goes off).
Worked fine all afternoon and accurately tracked a bit of driving and sat in the office connected all afternoon and all the way home and into the evening.
With run.gps running all day, three or four phone calls, half a dozen texts and a few emails, plus a bit of browsing t'interweb I got a total of 8 hours and 5 mins before the first low battery warning.

thanks for such an experiment.
I will drop diamond and get a orbit 2 soon. (my handler offered me a good deal, but I have to wait till the end of this month.)
8Hr gps recording is impressive. diamond is small but I am perfectly confortable with my xda mini, so orbit 2 with similar size and weight must be ok.
Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.
Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.
Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.
My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.
having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.
You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

Restart your phone in safe mode, and see the battery drainage...maybe it can help you.

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5
I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.
Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....
I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.
Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.
Update
Please refer to the OP for update. Thanks all.
battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?
It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

I can't believe it, but after the new update I still cannot get a full day on the battery. is this normal with always on?
Not normal. turn auto heart rate off, turn s-voice off, use a dark background to conserve battery while always on, turn on inactive notifications, etc.....
Thanks I turned off some things I turned off everything except Bluetooth but now it doesn't seem to be changing the time or updating the weather for the location I just landed in. Is there something that has to be on besides Bluetooth? Or can I have every single thing off . thank you

Apps have intervals. For example, the heart rate sensor by default is set to 10 min. Imagine the impact that has on the battery. Same with weather. You can set your weather to check every hour but you must turn on your phones GPS. The watch doesn't know where you are if your phone's GPS is off. You pick and choose what notifications you need with intervals while others can be manually updated.
For the most part, I have everything off on my watch except for bluetooth. I manually update weather, heart rate, i dont use voice search on my watch (Google assistant on my phone; ok google), my gear is LTE and I turn that off to save battery, etc... mostly, I use my watch for notifications and answer phone calls when I drive. If your watch isn't changing time while bluetooth is on, you might want to try another watch face because that isn't normal.

I suggest also powering down when you notice rapid battery loss. Some times for no reason after charging overnight, my battery just starts draining fast. Powering down and then up fixes the problem. Also, double check no app is running more than you'd expect. When Samsung updated the Mail app recently on my Note 4, I noticed the my Gear S3 showed super high Mail app usage. I forced stop the Mail app, and then all went back to normal.
Hi,
ever since I've bought my Gear S3 Frontier I have an issue with buggy GPS tracking with Samsung Health. Recently I'm exercising much more and it's driving me nuts.
When I start any training (regardless of high accuracy or energy saving GPS mode) it works fine as long as I don't click pause button and try to resume training later on. If I'm on high accuracy, it will reconnect after a while providing gps in a watch is enabled. If I'm using energy saving it never locks position again, until I end that exercise and begin a new one.
High accuracy tracking drains battery in just a few hours so biking for over 3 hours is out of the question.
Can anybody confirm that bug or have a solution?
EDIT: I can add the fact that it existed both in Tizen 3 and Tizen 4, including data wipes.
Hi, sleep recording in Samsung health in very random, deep sleep 15 min each night, not sleeping for 1 h and a half, clearly not accurate. Does it works better android app or simply the watch can't make better ? (GW 4 by). Also, while hiking, Samsung health stops recording hearth rhythm for 5-10 min, restarts again, stopping again and so on. Same question, with another app can I get better results ? Thanks for sharing your thoughts.

The Samsung sleep monitor in health doesn't work work a crap. It'll say I slept 2 hours when I slept 8, etc.. Download sleep for android on your phone and watch and use that. It works awesome. It even has an alarm setting that looks for the perfect sleep pattern to wake you up so you're less tired. I have mine set to only 20 minutes within my alarm time, and I feel pretty good most mornings. Hope this helps with that piece.
As for heart beat and such, I've never had an issue with both my watch 4 and watch 5. You might want to try a factory reset of the watch for that.
