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.
Bad Problem with the Battery
i have the TP and the bettery have a big problem it's ended in about 5 hours with no use.
how can i fix it?
is there any program to increase the use or tweak the settings?
from 5 hours no
change the battery
You have either some app running which consumes a huge amount of power (really huge! Even if you use TP as video player with the screen configured to full brightness TPs battery lasts for at least four to five hours). Or your device has got a faulty battery (which would probably be more likely).
Are you by any chance using Wayfinder Navigator gps-software? I found (the hard way) that this software doesn't close the GPS-unit in the phone automatically when you exit the application. Even after a soft-reset the problem persists. This will drain the battery in pretty much 5 hours. The solution is to manually close the GPS-connection in the WF Navigator program settings every time you exit the app (and hope for a fix ASAP). I've already reported this to Wayfinder, and they're working on it.

I was using a GPS related app the other day and the same thing happened to me. Try and find out what hasn't shut down properly...
10X for all
melcul-i think i will send an email to HTC about that
DeepThought-i checked if there is any programs that running but nothing is running acording to X-buttom 35% memory in use.
aBE-One- i am not using that app.just using QuickGPS and Nav N GO IGO8 and they are close.

what aBE-One is saying is that on his phone he had a similar problem, the software was closed but the GPS command remained active thus draining his battery, so your IGO8 might be shut down as software but there is a chance that the GPS hardware is still running in the background for no reason. go into your com manager and turn off GPS and that should resolve the issue

Exactly the same happened to me, after a full charge it took only 5 hours to an almost complete discharge.
I bought TP 1 week ago and it came with radio 1.02.25.17 with no battery issues at all but with the GPS issue -not finding sats-. After upgrading to 1.02.25.28 radio ROM, the GPS now works ok with TomTom, GPS test etc, but the battery now drains dramatically even in standby with no software running and all radios off except phone.
Is possible that the GPS radio stays on even after closing GPS software? In that case, is there any way to manually switch off the GPS module?. In TTN there's no a button to do this.
Mine too..
But i've observed this drain even before upgrating to radio 1.02.25.28
In 40 minutes from 78% to 69% (9%), in stand-by mode (short press power) without any running application!
And I've done 3 or 4 full discharge-full recharge cicles...
LE: No active moderator here? There are plenty of battery problem topics.. why not merge them? It's hard to chose in which one to post... Also, that's not the only case. See GPS related bugs, opera, etc. Too many duplicate topics.
Ok, more info:
I've drained the battery completely till the device turned off then I've left the phone on charging overnight (device turned off).
After about 9-10 hours I've unpluged and turned on the device. Used for 1 hour and 25 minutes in total (about 1 hour for browsing - not downloading, so data transfer was not continously - and the rest for music). With "Auto adjust backlight". The battery level gone from 100% down to 68%, so 32% battery drain in less than a hour and a half!!!
Now, after 4 minutes (device was in standby - eg: short power button press), I wanted to check something and the battery metter was on 66%... so 2% in standy/idle mode in just 4 minutes?!
@l1234 any updates?

That all sounds correct. I can be typing emails/sms with WiFi and phone on (not actually doing anything), drains about 1% per minute.
I read the other day that the percentage indicator is faulty. Some people have reported the battery draining down to 10% in a very short time, but then the meter will stay at 10% for hours before going down to 9%, etc. Has anyone else noticed this? If not, look for it and see if it happens to you. Also, open the power meter in the settings options and verify that it shows the same battery level. I've had that happen to me already where it would say 50% in the title bar but the power options still show 3/4 of the meter!

I have noticed that the battery percentage indicator does this. All in all, my device has better battery life after flashing a custom ROM, keeping screen brightness under half and leaving off bluetooth or wifi if possible. my battery will stay at 100% for hours, but if i soft reset, it drops 10%. other times it will drop right away but stay there. It really does stay at 10% or so though for ages before it drops further.

I was brosing via 3G/HSPDA connection. No WiFi/BT on.
Now, it seems that the drain in standby time is OK (haven't done something special, same processes opened.. maybe just now the battery can be used at its full performance, after some charges/discharges) - BUT when using the device the battery drains quite quickly..
I give you an example.
Battery was 100%. Browsing the internet with IE & Opera for 1 hour. Battery meter was on 75%. So 25% in one hour... tooo much... The display backlight is set to "Auto adjust".
Again, I'm not using Wifi/BT, push e-mail, etc. Just normal browsing (without downloads) with a 3G/HSPDA connection.
I've had my Fuze about a week and I've been testing out many of the available ROMs. I've noticed disturbing trend and want to know if anyone else is seeing this problem, and if so, how can we fix it? It seems like anytime I install a Raphael based ROM, I start to lose battery power at a fast rate - about 10%/hour, maybe even faster. With a cooked ROM based off the ATT Fuze code base, I do not have this problem. I get this even when I install the keyboard fix, etc. and I am doing a hard reset after install to no avail. Any help, input, thoughts or shared experiences welcome.

I am using PROven's latest 1.4 rom and the battery is amazing!!! I loaded it last night, charged it up around 9pm and at 5pm today I am still at 70%!!!
I've noticed this as well. I first go suspicious when after a long flight in airplane mode the battery drained significantly.
No I am in all day meetings this week so I am trying several combination to see what sucks juice and what does not by keeping the radio out of the equation.
So far it seems that RomeOS is a battery suck while NATF is not. This is with the device doing nothing but sitting there with no radio activity.
I've notice that the stock .32 radio on the fuze is the culprit (at least on MY fuze). After I downgraded to the .28 radio the battery life has easily doubled!
@NRGZ28
Which .28 radio do you mean?
1.02.25.28 - Extract Official Shipped Orange ROM ESN 1.90.75.3??
I'm using ROMeOS with 1.02.25.28 radio and I have pretty good battery life on the Fuze. I've also used some other ROMs here and no issues either in regards to battery. Is your data connection on constantly or is it configured to disconnect after X # of mins?
Okay so I noticed my Captivate seems to lose a lot of battery while in standby. To test this, I left it unplugged when I went to bed last night. I checked the battery level right when I went to sleep and then again when I woke up...
My battery drained from 64% to 31% in about 7 hours!!!
I know other threads discuss bad battery life. A bright screen and a 1GHZ processor can cause this so I can understand why the phone won't allow me to browse the web for 10 hours straight. But is everyone else getting an almost 5%/hour drain in battery while in standby?
Here is a little info about my setup:
-I took off an animated background and put one that is relatively dark (Screen is off during standby so I would think this doesn't matter)
-I have WiFi and Bluetooth enabled.
-I use both wireless networks and GPS for location.
-I have 1 Gmail account setup to check every hour.
-I have the Daily Briefing set up to check every 3 hours.
-I have the Slickdeals widget set to check every 2 hours.
-I have the Latitude widget running (you can't set how often it refreshes).
-I have the ESPN ScoreCenter widget running.
That's about all I did that I can think of that can possibly affect battery. I know I would get better battery with less background widgets, but all of this is in line with the amount of background services I had running on my last phone (Tilt 2) and that thing would last for several days with light use.
So, what I'm trying to find out is whether or not this is normal behavior that everyone is seeing or perhaps if one of the background widgets I'm using is known for draining a crazy amount of battery. Maybe I need to hard reset the phone? Thanks in advance for any ideas on how to lock this down.
In poor reception I could see that. But I'm good area that's too much. Like 2% every hour is good... 5 is too much....
Thanks for your reply. I had 3 bars of service where I was last night. Also, this isn't the first time I've noticed about 5%/hour for standby, just one example...
So it sounds like I'm getting worse drain than normal? Now, how to fix it?
Well...with all the email checks and having various Widgets check for updates..it will definitely drain the battery. I have been able to easily get twelve+ hours on standby without GPS on and turning off wifi when not at home or in a place with wifi.
Definitely can't go days without charging like I could with previous phones like my blackjack II buy I can get 12-16 hours with light to moderate use and 10-12 with somewhat moderate use of Facebook, wifi, various other apps.
EDIT: the Bluetooth as well will drain the battery.
Sent from my SAMSUNG-SGH-I897 using XDA App
I have very similar battery usage to use. About 5% an hour not doing anything. I am always around a wifi and leave it turned on. I have nearly an out of the box setup. Between the poor battery life and crappy GPS, I may very well be taking this thing back.
Under Settings > Wireless and Network > Wi-Fi settings > Bring up the Advanced menu and set the Wi-Fi sleep policy to "Never".
This has helped my battery life immensely, since I am around Wi-Fi most of the time. This way all your data happens over Wi-Fi instead of 3G when the screen sleeps. I disable Wi-Fi when I'm not around any APs I normally connect to.
Pulled phone off the charger at 6:00AM yesterday morning. Streamed an hour and half to 2+ hours worth of Pandora over wi-fi getting ready for work and then some in the car. Did some web surfing during the day, various other things. (No phone calls really, except a brief wrong number). 4 e-mail accounts checking every 30 minutes (one an Exchange server). Also have Touchdown running push e-mail for another Exchange mailbox along with the Touchdown widget. Played around with some GPS apps (new google maps, Places, etc for a few minutes). Battery was down to about 16% by about midnight last night.
My phone charged fully overnight (with power off). Was turned on at 7AM, it is now 11am, and am at 90%.
I do not use GPS, have nothing running, no emails or social networking status updates.. The phone is on standby on my desk. I only do a few text messages and 5 minutes of voice calls / day.
So this means I get 40hrs of standby time? That is a little ridiculous.
I chatted with AT&T tech support and they said that the AT&T stores don't have battery replacements yet, but I could get a full phone replacement since I am within the 30 days still.
But from what I am hearing, it seems most people are having the same issue if not worse, correct?
I really don't want to set everything back up AGAIN. I am coming from using a Samsung Eternity - understand it isn't a true "smartphone" - but I use it the same, and would easily go 3-4 days without needing a charge.
with GPS off, wifi off, BT off, no data sync or background data turned on, i charge it fully at night -
last 3 nights in a row, at midnight it was showing 100% and at 7:30AM it would show 97-98% remaining, and that was using the alarm, set to loud and probably ran 2 minutes before i'd hit the off button
From 7:30am-11am, I have used 4% of my battery. I have these things going on:
-Exchange sync (real time)
-Facebook sync (once every hour)
-wireless off, bluetooth off, GPS not being utilized
-Weather.com and a Google search widget
The battery use shows this:
-Cell standby: 48%
-Phone idle: 36%
-Display: 8%
-Android System: 3%
-Email: 3%
-Android OS: 2%
I've barely used my phone this morning, so I'd think 4% of use in 3.5 hours is quite acceptable. It sounds like you need to make some modifications to improve your performance.
firehazard - what modifications have you done? I have wifi/bt off, background data off, no email syncing - display brightness all the way down..
To anyone who is having very poor battery life, I suggest a factory data reset when you exhaust other options. My phone wasn't lasting me more than about 8 hours on a full charge, with light to moderate usage. After a factory reset, I just ran nearly 24 hours with similar usage.
I can't tell you what changed or what got removed, maybe it was an app that was running and draining the battery that I didn't see, but battery life is MUCH better now. Hell, everything is running much better, even the GPS.
I went from wanting to throw this phone at a wall and return it for my iPhone 4 again, to loving it in less than 24 hours.

I'm referring to him running wifi and bluetooth when he's not even using his phone. Stuff like that.
Just for recording keeping, when a phone company says their phone can last XXXHours in Standby this means, that all wireless transmitters are off. this means (for the most part) airplane mode, with bluetooth, and wifi OFF.
these continuous wireless transmitters are why you didnt get the 200Hours or what ever it is in standby mode.
I recently took my phone back to BestBuy for a replacement since my battery was trying to kill itself overnight as well. I did the full charge when I first got it and purposely ran the battery down to quickly get it to turn itself off at 0%. Did a full recharge and repeated this process about 3 times and last night my battery only went down 3% over 6 hours. Compared to the 30-40% that was draining before, I'd say the full discharge/full recharge works that people have been talking about in the battery threads works. Thanks, everyone! I use Y5 to have it automatically connect to my WiFi at home when it's in range. Not much more than the usual was left to sync (although JuiceDefender may be working to turn stuff off when my screen is off) such as Gmail, Beautiful widgets, facebook, and one rss feed.
Either that or I had a crappy battery before
Seems like some folks are having the same problem as me, while others are having much better results. Firehazard's situation and drain while not in use is pretty much in line with my expectations of the phone. With my old Tilt 2, I left WiFi and Bluetooth on all the time and still got great standby time out of the phone. When those connections weren't in use, they weren't really draining my battery in any way. I'm going to try to disable them though and see if that helps. I'll also try to monitor the battery usage screen and see how much power is going to wifi and bluetooth when I have them on.
I've been suspicious of my battery as well, tracking it casually today.
Took it off the charger approx 8:30am, immediately went to 99%.
Watching it over the last hour it appears to be losing 1% / 10 minutes.

Just using it for the past 5 minutes to write up everything running has dropped the battery almost 3%. Albeit I have terrible cell coverage where I am. It does seem that the cell and wifi receivers are a bit weak, or the meters are biased conservatively.
*edit* I want to be clear that I love this phone, I just want to try and find out what and if certain services/applications drain the battery and if not then if I have a bad battery.
Okay, so I turned OFF bluetooth and WiFi and checked the battery before bed and right when I woke up. This time, I lost 24% over 8 hours. Certainly a big improvement over 33% in 7 hours, but also no where near where my old Tilt 2 was. I would lose 2-3% overnight at the most with that phone. I checked the battery meter and the majority of the battery went to Cell Standby and Phone Idle. Those don't seem like things that can be avoided through tweaking. I was in an area with 3 bars of service (same as night before), so I don't think that was an issue.
I'm debating whether or not I should try a factory data reset. Some folks reported good results with that. I really don't feel like reconfiguring my whole device if there isn't a good chance for improvement. Maybe the GPS fix that's coming will help battery life?
Have you tried reconditioning the battery? That would be the charging/discharching cycles mentioned throughout the forum?
I have done it and my phone has been on standby for more than 24 hours and I am still at 50% battery. It's just had very light usage. Wifi on for about an hour, snapping a few pics, deleting some others. A bit of calc usage. When I first got it, my battery was dismal.
Mine hasn't been modded one bit yet, just installed some apps from the market and a weather widget.
Yes, tried that. It actually helped a little but I'm still getting poor results compared to some.
I have another theory/question. I use gmail as my only email account on my phone. Its set up through the system and it syncs to the gmail application on the phone. I also have it set up in the Samsung default email client (which I prefer). Am I wasting battery because the two apps are checking mail independently? Does the gmail account sync while the Samsung one checks at intervals (I have mine set to 1 hr)?

probably.
follow battery optimization guide in pimp my captivate.pdf thread. I get 1-2% battery consumption per hour with moderate to light usage.
heavy usage drops my battery about 4-5% per hour. By heavy usage I mean playing 3D games for hours str8
Hi everyone here
I got a concern about my TF101 Tablet.
When I switch my Tablet screen off and set the WiFi as turn off when screen off, my battery still drains extremely fast. From the pic you can see, my battery is running out from full to 10% in only 1day and 6 hours without any use. My GPS and bluetooth are also turned off in this period. From the pic you can also see my CPU load is over 30% at most of the time.
From the second pic, I can see the process "System" uses the CPU very hard
Can some one figure it out and I will appriciate it very much!
Here I have to bump...

I am seeing the exact same problem, not sure what the cause is either. I read somewhere about "wakelocks" where some app will try to keep the CPU awake when you try to go into standby and it results in high system usage.
Thank you for this thread, I am also having this problem. I think the problem for me may be because of Google Maps.
Basically, I'm running some tests now. I had massive battery drain overnight while I slept. The tablet would go from 90% down to 50% in an 10 hour period (4%/hr). It didn't matter if it was docked or not docked. I was running Google Maps v5.8.0 and saw some people post that the new version is eating up the battery. So I removed the updates for Google Maps and tried again.
Now I'm running v5.6.1 of Google Maps and the battery went from 100% to 42% in a 17 hour period with absolutely no use (3.5%/hr). I checked battery usage, and Google Maps is at the top and it's taking up 41% of what was used. That's ridiculous.
So now I'm going to install the latest Google Maps and see if this helps at all. I've also attached some screen shots of my latest tests.
Other details:
Wi-Fi is set to sleep when the screen turns off.
MobileDock Battery saving mode is checked.
Use location for Google Search is unchecked.
I did another test last night after having updated Google Maps to v5.9.0 (latest). I got the same results. Google Maps is eating through my battery when the tablet should be sleeping.
Here's the results:
The tablet was undocked, and fully charged.
I didn't touch the tablet for 15 hours.
The battery went from 100% to 55% in 15 hours = 3%/hr drain.
Google Maps was largest user of battery at 75%!!
I also did a reboot after I updated Google Maps to v5.9.0.
WTH is going on here?! Anyone have any ideas??

Try turning off all location services (WIFI/GPS) and see if the problem goes away. I did something similar and the sleep mode CPU utilization dropped back to 1% or so. I haven't yet enabled the settings one by one to see which one cis causing the issue.

You are correct. I am able to turn the Airplane mode on and see virtually no battery drain at night. But this is rather annoying to have to turn on airplane mode every time you are done using the tablet and turn it back off whenever you want to use the tablet.
The best option would be to locate the source of this issue and fix that. Tonight I'll be testing Google Latitude turned off to see if this fixes anything.
As a test I turned back on location services (GPS/Google) but unchecked the use WiFi for location and found the problem went away overnight. Only a few % CPU use. Not quite as good as leaving in Airplane mode but close. Lost about 2-3% CPU over 7 hours. WiFi use setting is to disable with screen turned off.
So after my test last night, I still had massive battery drain.
I turned off Latitude as best I could last night and still same result. Google Maps is chewing up my battery like no other: from 100% to 52% in 15 hours with zero usage by me. Anyone have any other ideas? Any other apps that might be causing this?

I had previously logged out of latitude and saw the same high drain result as you, so don't think it is that. When I disabled the WiFi location the drain stopped (leaving gps on). I agree it may be Google maps related since it uses the WiFi location services (since maps uses that service to locate the tablet along with gps).
I have a similar issue, but my problem is not with Google Maps. Instead, the main battery drain is "Android System." I usually leave my Transformer on standby 24/7 and used to only have to charge once a week. This problem appeared out of the blue a few days ago.
Google mail is the only thing on auto-sync, and this setting has never caused any issues in the past. Thus, I'm not sure why Android System is now suddenly waking up at random when asleep. You can see in the plot that System constantly requires 30% CPU usage once it happens, until I actually turn the device back on.
In addition, my wi-fi sleep policy is set to turn off when the screen is off. Recently, it seems it is always on, even when the device is asleep.
EDIT: The graphs from the OP suggest that our issue might be related, but the problem appears to manifest much more frequently for the OP. Crossing my fingers that next week's update somehow fixes this problem.

The system process was the same issue on my system as well (didn't show up as google maps). I confirmed that turning off the "Use Wireless Networks" under Location and Security stopped the constant 30% cpu usage when in standby.
After freezing Maps, which is the biggest culprit for me....i noticed, System Process' was way high now.
28%
After doing some searching.... came up with this
http://forum.xda-developers.com/showpost.php?p=16828183&postcount=605
At least for my case.
Google Maps battery drain Solved!
For me, I figured out the issue was Latitude.
I was getting bad battery drain overnight and Google Maps was the largest user by far. I finally signed out of Latitude completely. Battery drain dropped to around 2% (total) overnight! This is acceptable!
As it turns out, Latitude wakes up my device while it should be sleeping in order to update my location and therefore draining massive battery overnight. I'm going to post this as a bug with Latitude/Google Maps because this is causing waaaay too much battery drain.
So it looks like I won't be able to leave Latitude signed in. Once I'm done using it, I will have to sign out of Latitude. This way I can leave Wi-Fi on and set to turn off when the screen turns off. Thereby I get really good battery life again.
On a side note, my phone has the same behaviour, but I never noticed it because I'm usually charging my phone at night. So Latitude...basically...sucks (battery).
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.
It seems good for me

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)
