3g constantly in use???...

I am having battery issues, almost to the point that I want to take this beautiful phone back. I have adjusted every setting I know to adjust, including the CDMA fix (was already on cdma). I am getting about 6 hours max out of my phone with light usage (maybe 20 mins worth of calls, 10-15 emails, 10-20 text, 15 mins. or so of internet/facebook usage). One thing I notice a lot throughout the day is that my 3g upload and download arrows seem as though they are lit up more times than not. I am wondering if there is some hidden fix that maybe I am missing that would help with this. I checked sprint.com's data usage tool and see that I have downloaded 1.2gigs of info in 3 days (seems excessively high to me). I also notice today that my phone was pretty warm to the touch for a few hours straight. Back to being cool now.
any help or ideas would be greatly appreciated.

Get a task killer, that is most likely caused by background application traffic.
You can also uninstall some apps that may "poll" the internet that you happen to not use.

Got Advanced Task Killer already set up to kill on screen close. Appears as though my damn calendar is literally sucking the life out of my battery and I have no idea how to turn it off. Went in to Applications and did a "touch to close" deal, but returns. This phone may be making a return back to sprint...nice toy, but actually need it to last more than a few hours at a time. Any way to delete calendar without rooting?

Do you also have a sync symbol always lit up? My EVO had some problems with syncing and wouldn't allow me to go into the Accounts and Sync settings. My fault - I had removed some .apks that it turns out I needed so my phone was constantly trying to poll it and giving me 100% Running time. Download Spare Parts and look at your battery history and see if you're getting Running to be high, or look at your Up Time versus Awake Time.
If they're high, go into Accounts and Sync in your settings and look at the options there. You may just need to turn off Auto-Sync to fix your battery issue so that it stops constantly polling your calendar.

[Q] Battery starts draining at exactly 5am.

I started using JuicePlotter yesterday, and noticed that at night my battery barely drains, if at all (hooray for setcpu!). Until exactly 5am when it starts draining heavily at a steady rate. I've done all of the obvious stuff (I think), like making sure I have nothing set to begin syncing at that time, but I can't seem to pin it down.
Does anyone know of a way to find out what's turning on at 5am and draining the battery?

Do you have an Exchange sync setup?
If you do you may want to check and see if your Peak times start at 5AM. If so you may want to set it to update less frequently.

Does JuiceDefender run on a schedule and keep 3G off until 5am?

Thanks for the suggestions guys
I have exchange set up, but its set to "as items arrive" for both peak and non-peak hours (which is set to 8am anyway - yeah, being on call 24/7 sucks).
I'm also not using any kind of timing app like juice defender to schedule anything.
One wierd thing I noticed that may be tied to this, is that certain apps like twitdroyd and fb update immediately when I open the apps, even though they're set to refresh manually, and not to update when I open the apps. Still trying to figure that one out.

Night mode is enabled from 2 am to 5 am. Depending on your settings, Data/3G/Wifi are disabled between those times.

He is referring to JuiceDefender, I bet. I would guess a lot of people who use JuicePlotter also use JuiceDefender. It does exactly as he described: turns data off from 2am to 5am. I use it, and it does help. It also keeps data off when the screen is off during the rest of the day, except for a quick check every so often.

rats - I was hoping he was referring to something in regular settings. I'm not using JuiceDefender, or anything similar.

well if you do have it setup for everything to be off between 2 - 5 then wouldn't that make sense that as soon as 5 hit your apps will start syncing even Google apps as they have been trying to sync that whole time and just started queuing up and finally your radios turned back on. I have not used juice yet so i do not know much about it just throwing in some pennies.
One other thing the refresh manually is only for when the app is closed as soon as that app opens its going to sync with its servers. When you set it to manual then that means when you open the app you manually refreshed it and the phone did not do that while idle or you were busy on some other app. Its like twitter for desktops if you set your refresh manually then while the app is open it will not refresh until you hit refresh

One thought: Do you have a good signal in the spot where your phone sits at 5am? A bad signal is the best way to drain a battery fast. A friend's house has an awful Sprint signal, and my battery will drain in four or five hours there, even with no use, whereas I get well over 24 hours with average use in good signal strength areas.
Back when I first got my phone, I used System Panel to figure out what was causing the battery drain. I liked using it so much, I even ended up purchasing it. The history part is what you want, and it will work without paying for a bit, so you can find the problem.

that would make sense if I was running something like that, but I'm not - as a part of my job, I need to be able to reply immediately to specific emails. At any hour. Total PITA, but hell, it's better than not having a job, right? JuicePlotter's pretty neat though - it just sits in the background monitoring your battery levels and graphs them. For example, it was showing an almost horizontal line from when I stopped using the phone the night before until exactly 5am when it started a gradual decline.

Are you sure about this? I mean it makes sense, but I would be willing to swear that back when I was running stock I would open FB or Twitdroyd and it would wait for me to hit refresh before syncing with their servers. Twitdroyd, for example, I would set to keep 80 tweets, and I would check it only occasionally, so I could read those 80 tweets whenever I wanted. Now when I check it, because it syncs immediately, I lose anything older than the most recent 80 tweets. As a workaround, I've increased the number of tweets to keep, but it's still annoying.

ok so hmm what rom are you using. not wanting to bash the dev but could it be that rom?

My signal's not great, but the phone didn't move between 4am and 5am, and the battery only started draining at 5am.

I actually purchased SystemPanel this morning with the hope that it would help me get to the bottom of this (I had been using the free version for a while, and now I had an excuse to buy it). It shows me history of battery, device usage, and cpu activity, but even if I see that the cpu or the device is being used, I'm still not sure how that's going to help me pinpoint what's going on. First I need to build up some history anyway though.

[Q] 100% full charge to 0% in 6 hours??

I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?

Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

I have to leave for work now with out a phone, I will try to check up via computer (feeling like a dinosaur).

Ha ha I know I feel so bad when I don't have my phone. Maybe see if it happens again tonight. If it does I would get on to the carrier. Have a good day at work!

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery

If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck 

My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings

how do you disable drm? and what exactly is it?

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.
Good luck.
BTW, both actions can be reversed.

[Q] High "Awake" vs "Screen On" time

Let me preface this by saying I'm not complaning about battery life as 36h is very good. That said, I feel like my phone is awake much longer that it should be. Anyone have any ideas why my Awake time is so much higher than my Screen-on time?
Once again, I'm not complaining but considering my phone was awake almost 5x longer than the screen was on, I feel like I could squeeze some more life out of the phone. I had 1 exchange account @ 15min, 1 gmail on push, no talk/g+, ~2-3 hours off wifi (4g), gps on, bluetooth off, 4.0.4, leanKernel.
When analyzing the wakelocks, I don't see anything that would explain almost 6 hours of extra awake time:
Considering most of this charge I was on wifi, I think I should have been able to achieve more than 1.5h screen-on time. Especially when I see people getting 4-5+ hours on theirs. What could be causing this seemingly excess awake time?

Since those screen shots, I've done another full cycle and here are my results. Same settings as before. It looks as if I did a bit better with the ratio of awake vs screen on, but I still only got ~20 hours. I'll admit, this had much more 4g time and heavier usage.
As you can see it's better, as it was only awake about 3x as much as the screen. You can see where I was at home in the second screenshot (The long bar of wi-fi) and that included me sleeping yet it shows that the phone was consistantly waking up overnight without any usage. Short of "email", I'm not sure what could be causing it. I got MAYBE 3 e-mails overnight.
Signed out of talk/g+/latitude
Location services was NOT disabled in either set of screenshots. Disabled it and charging now. Maybe that will help?

Have you checked out your wakelocks using BetterBatteryStats (found here on XDA)? Also, download CPU Spy from the market and check how long your phone is in what state. If it isn't in deep sleep too often, you might have an app or service keeping your phone awake. Background Data of any kind usually does that. Also, the first culprit I would investigate is Google Maps. Uninstall that bad boy and test your phone out. I am betting you that 60% of the time, the problem with your phone being awake too often is with Maps running unnecessarily in the background. And to be clear, Maps self-restarts itself even after logging out of Latitude and closing the app completely

I have attached all the wakelocks to the previous two posts. I didn't attach CPU spy but I did check it every time. Usually it's between 60-80% but most often it's >70% in deep sleep.
Just did a fresh wipe with a app restore using the market. Location services have been disabled. I have uninstalled all gMaps updates and disabled the app. Is this good enough? Should I convert to user and uninstall using TB?

Just wanted to chime in and say I'm seeing a very similar profile to what you posted. And I'm not entirely sure, but I think this started when I flashed this ROM. What I feel like I'm seeing is that active use of the phone seems to be more of a drain than it used to, but I'm not sure how much of that would be placebo (i.e. remembering when I first got the phone around the holidays and there were a lot of relaxed days at home with constant wifi).
But right now I'm seeing 5.5 hours of awake time and 1 hour of screen on time, with 27% remaining. Total time is 42 hours, which seems to round everything out to a decent battery life, but again, 1 hour of use for 70% of the battery seems lower than what I remember. Not sure if a vote for seeing the same behavior is one for this being normal or us both having the problem, but I can try to post screenshots/more detailed info later if it would help.
This is on the above linked rom with stock kernel, 4.0.4 radios.

That's the same ROM I'm using and I agree, 70% usage for 1h screen time seems too much. I've seen people get over 2.5h screen on time on pure 3/4g
I'm going to see if disabling maps and location services help. Will report back.
I would be interested to see any SS you have, might help.
Sent from my Galaxy Nexus using XDA App

This is after a fresh wipe, fresh kernel install, no maps, no g+, no gTalk, no GPS, no location services, just gmail and 1 exchange @ 15 minutes
Any advice as to what's going on would be very helpful. Thanks in advance.

I also have a problem with wake-locks.
Since phone is relatively new ~2weeks its still stock 4.0.2 GSM. After some time my battery life fell and thanks to XDA i think i found the problem Google backup.
I disabled Google backup to see if i get the same awake time tomorrow.
If the problem doesn't go away, is it possible to resolve this problem without factory reset of the phone?

Here are some screenshots I made the other day, taken a bit into a charge but immediately prior the phone was down to <6%. Didn't get a capture of the kernel wakelocks but as you reported, the screen on time falls far below the wake time, and the wakelocks don't seem to come anywhere near to explaining the difference.
I just installed the 6.3.0 google maps, which claims to increase battery performance for location and latitude services. I'll try to make a comparison next time my battery is drained.
I've signed out of latitude before but generally don't redo this upon rebooting the phone. Does it sign in by default on every reboot?

Well after disabling backup thing im still getting 90% wake time from backup service so i will try to do a factory reset over weekend and hope it goes away... Will post resoults in case some 1 else gets this problem.

This looks to me like some sort of Maps issue. Try to uninstall/disable maps and see if it goes away. Looks like it's stuck trying to locate you with maps somehow based on those wakelock names.

Hopefully the factory reset will fix it, that is an odd problem.

It seems to me like my problem was the version of leankernel I was using. I went from 10.0exp2 to 2.01exp2 and it's much much better

Actually, the kernel upgrade did not fix my problem. I did seem to figure out what was happening though.
This entire time I've noticed that my phone would standby and sleep very well on Wi-Fi but when I switched to data it seemed as if I would bleed juice. I discovered that my "Keep Wi-Fi on during sleep" was set to "always" and I believe that was causing my excess wakes.
I've changed it to "Never" and I'm doing some tests. I'll be sure to report back if anyone is watching this thread.

mine is opposite of that, i standby fine on data but terribly on wifi. im guessing that is background syncing. i just have to figure out what is doing it

i have my wifi set to never too for better battery life. It seems counter intuitive, but wifi is better on power than 3g/4g. So preventing the phone from leaving wifi back to cellular is better for battery. All my phones have been like this.

yeah thats what i thought it does but mine drains faster on wifi...i leave it on cause i barely get signal in my room an if i sit on 3g it just takes a long time to do anything

What type of drain do you get over 3g vs wifi?
Yesterday I was playing around on 3g all day and I was seeing an average of 6%/hr. My phone is consistantly awake 20-25% of the time according to betterbatterstats. Screen on will always be far less than half of my awake time. Wifi drains around 1%/hr
I did a wipe of my 4.0.4 install and flashed a fresh kernel download. I'm not logging into exchange because, for some reason, I think that's my problem.

Also, changing to Never didn't really fix my issue.

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?

might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

System panel paid version with monitoring enabled is the best for tracking apps using CPU.

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??

Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.

1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.

I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.

You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

when i did a complete quote and re flash i did not setup the exchange account, but the issue continued.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.
