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.
TL;DR version:
1)Start Google Navigation, pick destination, start driving. Result: Sporatic or no lock and definitely no turn by turn working.
2)Start Google Navigation, pick destination, start GPSTest, start driving. Result: Almost constant lock and turn by turn works astonishingly well.
What gives?
Alright, please read this whole post, try it out, then comment on whether there is something to this or maybe I'm just crazy (a very definitely possibility). I was playing around with the GPS today and tried the Vibrant GPS hardware fix (pulling up the contact so that the GPS antenna is making better contact with the metal back). There wasn't much of a difference, so I decided to take the back off and run the GPS without the metal backing. I found that interestingly enough I was getting a better SNR with the back off than with the back on it was 8/8 at about 25-30 with the back on (using GPSTest) while with the back off it was 8/8 with 30-35.
Now comes the really interesting bit. On my drive home today I decided to see how well I could hold a moving lock. I turned on Google Navigation, pointed to my house, and started driving. Needless to say I was not able to hold a lock for very long. However, if I left the navigation app running and started GPSTest, all of a sudden I was getting the turn by turn voice pretty accurately. I then exited GPSTest and probably 10 seconds later lost my lock again. Open GPSTest, BOOM lock back on and turn by turn working again. Am I just hitting a really lucky coincidence or is GPSTest doing something we're not aware of? Please post here if you can either a) replicate what I'm seeing or b)think I'm blowing smoke cuz you aren't seeing a lick of difference.

BTW... this is GPS Test by Chartcross Limited, NOT the one by Mike Lockwood. You're welcome to try both however.
Previous GPS threads have repeatedly documented the positive effect of moving your nav app to the background. Theories on it center around backlight, temperature, or CPU/GPU. My own myTracks tests seem to point towards CPU/GPU. Or, at least, they seemed to rule out temperature or backlight as a factor.
So did you have GPS Test in the foreground during this test? This will pretty consistently give you improved performance over having Navigation up. If you turn the screen OFF altogether, it almost works as well as a real GPS! Check out the difference by recording a few drives in MyTracks -- it's night and day, on my phone at least.
My personal, uninformed theory (guess) is that the CPU/GPU and screen during Navigation are starving the GPS subsystem of power, causing either reception issues or causing the clock to desync and lose the position of the satellites it's tracking.
Ah well, such is life.

I noticed this as well with my old setup (phone bought in August 2010 running Cognition & JK4 radio firmware). I got one of the refurbs from the random power off fiasco and GPS seemed to be just as unreliable. I've recently flashed the JL2 radio firmware, and GPS locks on within seconds and stays locked around town - as it should. I think a lot of people's issue would be completely resolved if they played around with radio firmwares...

Yeah, GPS Test was in the foreground, navigation in the background. I get the feeling however its more to do with the application than the hardware. I say this because having other apps in the foreground doesn't quite have the same effect for me. Is that the case for everyone else as well?

this worked really well for me. am on andromeda 3. but was getting on locks without staying on continuously. with the approach. gps was spot on.!! a BIG Thanks
I've noticed this for some time when running the GPS Application Test in lbstestmode. Run the GPS test first and then move it to the background and launch your normal GPS program and you'll usually be better off. Needless to say, I'm doing another warranty exchange in hopes of getting one with better GPS hardware soon.
Try this:
Get a mobile hotspot (or someone who has wifi tethering enabled on their phone). Put your phone into flight mode, then turn WIFI on and connect to that mobile hotspot. Fire up navigation, and go for a drive. You'll be amazed at how accurate your GPS is.
That leads me to believe that there is an interference issue in the GSM/GPS antennas. Part of the reason why putting navigation in the background helps improve the GPS performance is because it stops refreshing the map, which means it's not trying to use the GSM radio. But if you fire up Pandora, even with Navigation in the background, the GPS will start going nuts again.
I'm pretty sure AT&T is aware of this, and I even think they have a... well, not a fix, but a way to mitigate the problem.
A friend of mine did a warranty exchange on his Captivate last Monday for a problem with his USB port. The Captivate he got in exchange has been getting much better performance with it's GPS. And since his worked just fine all week, I exchanged mine yesterday. Now, quite often after flashing a new ROM, the GPS will work fine for a day or three. So I'm not going to be convinced mine is working as well just yet. But there are some notable differences from what I've seen before... When I'm tracking my position on Google Maps, my actual position now stays within what the GPS reports as it's error, even when I'm driving around. Previously, my phone might report a 10m error, but my actual position might be 200m or more from where it thought I was. In addition to that, I'm seeing that my phone is locking into more satellites, and holding that lock even as the SNRs drop due to obstructions. And finally, my GPS works just as good while it's in the car dock, whereas before it would only intermittently get enough signal to fix a position. Overall, while my GPS still isn't as good as other phones I've had in the past, it is now actually good enough to use and trust.
I think that AT&T isn't advertising this because it's not something that they can push out over the air or through a Kies update. I'm guessing that either they modified the antennas slightly, or that they installed a new firmware to the GPS chip (at a lower level than the driver)... or maybe both.
Either way, my friend's GPS has been working great all week long, and mine appears to be doing so as well. I'll not say that it's permanently fixed yet, but I'm cautiously optimistic. We'll see how it's doing after another few days go by.
UPDATE 3/28:
Two more days of testing have passed. So far, the GPS is holding up nicely. The only issues are with the car dock. When the phone is in the car dock, the GPS will occasionally drift 5~10 meters off of my position. This doesn't really surprise me, as the electronics in the car dock are right up against the GPS antenna, and simply putting the phone in the dock will drop the reported SNRs by more than 25% - usually a lot more.
Still, even with the car dock, the GPS is perfectly usable. And without the car dock, the GPS is now exactly what it should have been from the get-go.
I've also found that if I run either gps status or gps test to get the fix, then start whatever app I need to use, the performance is much better. Recently I just use lbs test to get the fix, then proceed with whatever app i need to use. Seems to work better, as lbs test continues to work in the background
i have seen this in the past but trying to prove that it is not random has been a problem as i cant repeat the results.
also i dont thing i have ever observed the phenomenon while using control plane mode.
maybe another coincidence, i cant tell but i have been using the control plane version of da_g's fix for a couple months now in combination with the jl3 modem and have gps that many smart phones would envy. i find jl3 to have the most stable positioning and tracking, less blue circles ect. i also find agps settings to hinder tracking. i only set agps mode to standalone. not sure how supl works or if controlplane supl setting is actually doing anything because i was under the impression that supl was part of agps but it is a combination that started working for me and i am sticking to it.
Hi to all,
after a lot of test I can confirm I haven't the dock draining issue, but I've some (application) what's consuming my battery...
You can see some notes to the attached image.
How can I know what's eating my battery? The 10 hours before, the tablet was in sleep mode (no using)...
Thank's in advance!
you leave it on the dock while sleeping?, get system panel or similar to monitor device usage
During this 2 days and a half, the tablet it's always on the dock (docks battery expressly empty, 3-4%)
When I arribe at home (one hour), I take another screenshot, but basically shows... (aprox.)
Android System 40-45%
Wifi 25-30%
...
In an hour I post more info.
Thank's.
the other screenshot attached
It looks likes you system is never going into a deep sleep.
A couple of suggestions to track down what is effecting you.
1) You have pretty high Wifi usage. Do you install any applications that periodically check for data (some news apps do this). Also, is Wifi set to run off when the screen goes dark.
2) Are you running apps that use the GPS like Google maps or a another mapping app.
Thank's for answer...
Yes, I also noticed the wifi it's ON too much time... I have the option "When screen turns off" on Wi-Fi sleep policy... seems that didn't work??? In any case, if you look the first screenshot, on the middle, you can see a long time periode where the wifi it's on but the battery remains with a good rate of discharge.
I'm not sure if I've some apps using location but I'm sure the GPS it's OFF.
Have you enabled latitude under maps?
I'm running 4.2.2 Jellybean on the new Droid Ultra. Motorola Smartactions are now gone and I can no longer have GPS come on automatically when connected to my car's bluetooth.
It looks like the only option now is to have my GPS constantly on. I wanted to know if Google Now constantly uses my GPS location and will drain my battery.
I've tweaked the settings on my other apps not to use GPS based location. I don't see this setting on Google Now.

For some reason. After enabling google now and with that, enabling google to use anonomys location data, Maps seems to be running in the background sometimes. Google analatics is also a culprit, it's running in the background too.
Google now doesn't use your location data(gps) 24/7, but it does tend to gather info based on your location now and then.
It does this so it can suggest more relevant location info via Google Now.
Not to good for battery I've experienced.
Google Now only uses GPS when you activate it.

Google Now definitely does *not* constantly use GPS. Right now my phone shows 4 minutes GPS use in the last 4 hours (a short walk home from work).
Google is keenly aware of the tradeoff between location accuracy and power. That's why they created the new Location APIs: see developer.android.com/google/play-services/location.html (sorry no links).
The idea is to use the least power-consuming sensor to get the desired information. For example, the phone can use the accelerometer (which takes almost no power) to see if the phone's moving. If it's not, then there's no need to update the location. If it can figure out roughly where you are from WiFi (at Starbucks again!) or the cell network then it may not need GPS. Even when the GPS is used, it needs fewer readings when you're walking than when you're driving.
Between readings, Android will try to put the GPS in a low power idle state to avoid a 2 minute cold start. Whether it can or not depends on the phone's chipset and the manufacturer's firmware.
Google Now wants to track your location so it can guess where you're going. I think it's cute, but then it doesn't use much power on my Galaxy Nexus.
The power-vampire is more likely to be a 3rd party application. As an Android developer, I know it's way way easier to just fire up the GPS when the app starts, or even before it starts, and leave it running at high speed (i.e. high power) even when I'm not using it. It takes much more effort to use GPS sparingly and to throttle it as a appropriate.
Suggestion: Leave GPS turned on for a day, and check the power usage under Settings / Battery. Then turn it off for a day and compare. You can tap the Google Services line for details, including GPS usage time.

Great info in this thread guys. Actually came to this forum to ask a couple questions, and this thread already answered one!
Hi, I really did some research but I find alot of ROMs and Kernels and I always get lost. I just need a good safe way to better the battery life of my Nexus 5 and keep it's stability and all the functions it has. So I wanted to ask what you guys recommend as Kernels, apps and lastly (I dont want to change unless its worth it) ROMs.
Sorry, its been hard without a PC to do decent research.
Enviado do meu Nexus 5 através de Tapatalk
The ROM has very little to do with battery life. It's all about the kernel or the apps.
We can't recommend kernels (or roms) as this is against the rules. They will all pretty much help with battery life. Just try them all- yourself.
Apps:
Greenify
Better battery Stats
That's it. Anything else I would recommend is going through all your settings and turning off things you dont need like location reporting etc
if battery life is all you are looking for... the difference are ... not much
Just disable google apps that you do not use, then you are good to go.
Locations settings, always off, activate only when needed. uncheck all under Google Location Reporting.
Disable NFC if not needed.
If you don't have good LTE coverage, change it to 3G under mobile networks.
For maximum battery life, do NOT activate Google Now.
eg. (These are apps I've disabled)
Drive
Earth
Email
Exchange Services
Face Unlock
Gallery (I use QuickPic as alternative)
Gmail
Google Hindi input (These ones gets disabled once you uncheck them from input settings)
Google Play books
Google Play Games
Google Play Magazines
Google Play Movies & TV
Google Play Music (I use Poweramp *Paid)
Google+
Keep
Maps
News & weather
Quickoffice

What he said ^^^^
It doesn't matter what's on your phone....you should be able to get good battery life. Its all about setup and usage.
Just gotta troubleshoot issues occasionally.
Please check the thread linked above, and read read read. . (Start on last page and read back for a bit....a lot of good info)
On my phone it certainly seems to have something to do with signal quality. At home, I can put the phone next to the bed at night with it fully charged and wake up with it at about 95 or 96%.
At work a fully charged phone just sitting on my desk drops to about 90% in only a couple of hours.
The signal quality in my building at work is pretty poor, so I'm guessing the phone is using a lot of extra energy desperately searching for a better signal .

Poor and searching for signal is probably the biggest battery drain there can be.
Get gsam. And after your at work a few hours, open and click on "phone radio". It will say how long your phone was actually searching for a signal. That's a huge battery killer.
The only cures, get on WiFi. Or go into airplane mode. Toggle off data might help, then you'd still get texts and phone calls.

I do have wifi on in both locations, so the wifi part of this doesn't help. I suspect data isn't the issue, just the cell connection. My old phone used to randomly reboot inside this building when trying to get a signal . I guess I should install gsam just to verify, but the signal is really the only difference between work and home, so I'm pretty sure that is the issue.

I do have wifi on in both locations, so the wifi part of this doesn't help. I suspect data isn't the issue, just the cell connection. My old phone used to randomly reboot inside this building when trying to get a signal .

Usually battery drain from a low or bad signal is only a big issue while on data. On WiFi it doesn't affect the battery much , if any. Its from apps trying to sync through data on a bad or no signal. So on WiFi, that's not an issue.
At home I get fairly poor reception...sometimes only a bar...with some time spent searching for signal, but my battery times are at their best at home. On WiFi.
It could be a network issue. Some devices on networks can affect your device by spam polling your phone....might want to also get wakelock detector to see that. If the LAN is draining your battery, there will be wakelocks from it.
Try gsam and compare work results to home results. Especially good would be trying at least a few hours of total standby to see the difference at both locations. You'd have to reset gsam stats to start your standby test at all zeros though. A reboot will reset gsam.
Good luck!

And disable autostart from programs like poweramp which start on boot...use romtoolbox and autostart manager
Of course, pay attention to what you're going to disable
If You will try and You have some doubt ask here
I use a lightweight aosp ROM, a minimal gapps package, stock kernel, disabled some programs from boot and run in background...and battery duration is good
Don't ask to us roms/kernel combo, please Questions like your are not allowed on xda
Always read the users feedback and make Your choice
And... My doubt..is it really needed to change the kernel ??
Give stock kernel a chance... That's all I can say...
And make sure to charge your phone the right way
Hi! Anyone knows if I can disable the processes that Viber starts every so often? Like the in-app processes, it keeps on running in the background consuming a huge chunk of my battery. I already emailed Viber about it but unfortunately they don't have a fix for it.

OK, I turned the phone off, charged it to 100%, then pretty much let it sit doing nothing after rebooting. After sitting overnight at home (where the battery doesn't drain much) the "Phone" app was way down in the list:

Did the same recharge with phone off at work, rebooted, then let it sit on my desk for just a couple of hours, and "Phone" is now the 2nd biggest culprit in the apps list:

Wifi was on in both locations (with a good signal), I even turned off location to prevent that overhead. It just hates the environment at work .

I think that is just the difference in signal quality. It seems to be pretty common to get degraded signal at work places due to larger structure sizes as well as more users per cell tower.
Phone Idle is from the voice network, Cell Standby is from the data connection.
Is it normal for Google Play Services to be running in the background always? The gcm and the location service is always on.
