So areas with lower signal results in more wakelocks if it is indeed the radio??
Just wondering sa I do not know how to interpret what the status update means.

That's the logical conclusion, yes. Or even if hopping between different areas.

Oh so people should just stop caring that this thing is causing their phone to be awake for 50% of the time it's off the charger? People should just stop caring that they get 10 hours off charger and 2 hour screen on time before battery dies.
No.

Not what I'm saying at all. I'm saying that this probably isn't the reason for your battery drain.

Making strawman arguments do not contribute to the overall discussion at all. There is very little concrete evidence and reasoning to support that the kernel wakelock has been a factor for battery woes.
And if you're only getting 2 hours of screen on time with 10 hours, you honestly need to check for rogue apps. I'm constantly getting over 3 hours with over 15+ hours off the charger.
Plus, I would think that a developer would know much better than others in this thread including me, which the initial information was derived from Ricardo.

I believe a change in signal strength will wake the phone to record such a fact (the modem raises an interrupt which in turn wakes the phone from Deep sleep but it will return quite quickly to sleep once the data is recorded), this is how the battery usage chart can show the strength (in color) of the mobile signal in the chart, also other battery stat apps will show the percentage of signal strength between 1 and 5. Interestingly I think this is disable on the HTC One X as it never registered anything other than medium signal strength, probably a tweak by HTC in order to save some battery power, they turned off the interrupt.
Every wake up will use a bit of power but the CPU is designed to wake and sleep.
More worryingly I've had some instances where the Nexus has stopped entering deep sleep state, see link here http://forum.xda-developers.com/showpost.php?p=35215730&postcount=20
So far after I identified the reason in my case the phone might have been remaining awak it has been deep sleeping fine and the battery is great.

The forum isn't a link sharing website so unless you've got something useful to say and post please don't just post a link. Weak/changing signal has always resulted in poorer battery performance but maybe that's stating the obvious. Either way thread closed.

Google Tech Support says Patch for Battery Drain Coming Soon

I decided to call Google Tech support for the answer to ask whether the ear piece buzzing is causing battery drain. That's my only concern. I don't care if there's a buzz (the iPhone 4S had it, as did the GN, as do a few other phones).
And the fella I spoke with says the earpiece buzzing is not the father of your baby (/Maury mode) -- I mean, not causing battery drain.
He said it's a manufacturing defect and they'd be happy to send a replacement unit (I said, sure) but he assures that they've looked into it and it's not causing battery drain.
He went on to say Google is planning to send out an update very soon to patch a few bugs, including battery drain issue.
The gentleman sounded legit, but who knows. I hope it is true.
I urge y'all to call Google Tech Support and ask the same. Let's see if there's any consensus.

Pretty certain he's correct,
Hasn't every nexus phone received a fast point release update that fixes a ton of things, improves performance and battery?
Doubt they would change that with the Nexus 4.
It would have been 4.2.1 but due to the December bug, it will have to be something else (4.2.2 probably lol)

wtf is this "battery drain issue?"
For as long as smartphones have existed, people think there are:
- Battery drain issues
- Wifi issues
- Freezing issues
Most of the time the first is caused by a rogue app or bad reception or a combination of both. The second is usually a router issue, and the third is usually a combination of apps interacting or a cell phone that has too much crap installed that just needs a clean wipe.

+1 on the "bad reception" part. I just got a signal booster from T-Mobile for my house (I work from home). Before installing it, my battery was generally around 10% by bedtime. The last two days it's been 40% and 50%. It's a very noticeable difference.

Yeah. Android phones perform notoriously badly with low signal. I lost 30% at work in 1 hour because it kept trying to sync. Compare that with usually going home with 40% left.
Anyway I'm not saying battery can't be improved on this phone. But there really isn't a drain issue present.

Then how would you explain that most nexus 4 drain over 2-5% per hour while idling around doing nothing?
And how about you fix, for example, the msm_hsic_host wakelock that's active up to 50% of the standby time? Come on, I'm sure you can do it with killing background apps!

Yes, custom ROMs are already addressing certain issues. the battery drain and other stuff are definitely present in the stock firmware.
Guys, there are a lot of battery issues threads & guides & faqs and whatever on XDA. Look, for example, for one in my signature. Though it's for my previous device, most of things are still relevant.

There certainly is an issue which I've been suffering. Note in my case there is nothing recorded in the usual battery usage statistics to pin point any problem.
I found overnight and excessive daytime power drain in my case is because the CPU isn't entering deep sleep (using CPU Spy). Typically deep sleep should be in the 90 plus percentage range of all states. In my case it was spending 90% or more in the 384MHz state, so it was never really sleeping, and hadn't entered deep sleep at all, it was an unused state! This causes two problems, one, even though the CPU power drain is small, it adds up over the course of a night or day and eats power, and two, it also means the OS is up and running, so all applications are alive and any app that wants to ping home, download some ads or sync is free to do so which means the cell connection is constantly being kept active trickling packets of data back and forth, causing even more power drain.
Yes an application that has permission to stop the phone from sleeping is often the cause, in my case however battery stats showed no application keeping the phone awake, so I was baffled.
After a lot of troubleshooting I think it might be an issue with applications writing to the emulated SD card, perhaps keeping a file handle open, and this stops the phone entering deep-sleep at a low level in the kernel. As it is happening deeper down outside of Android it doesn't need an application with a keep awake permission to keep the phone awake, and also evades androids battery stats.
In my case I was running Bootlog Uptime, a small app with no permission to keep the phone awake but it does have permission to modify the contents on the SD card and I assume updating a log file on the SD card during the period the phone is awake, probably in order to detect a crash. As soon as this was uninstalled, even without restarting, my phone started deep sleeping.
Now overnight in flight mode it started out with 82% battery, and 9 hours later still had 82% battery! Now out of flight mode, it's been on for a few hours and has just dropped down to 81%.
Note that his application is running happily on a Nexus 7 and HTC One X without causing any issues, hence I think there is some driver in the kernel for the Nexus 4 that is incorrectly refusing to allow the CPU to deep sleep if it sees some activity in the flash memory.

[Q] Real life HTC One talk time, 5 hours?

My several day old HTC One is a fantastic phone (best I have owned yet), but I'm having to be very careful to keep the battery lasting an entire day.
In particular I am noticing that voice calls are the biggest drain on my battery.
2 hours and 20 minutes of talk time used 55% of my battery life yesterday.
I have read multiple sources with tests pegging the talk time at 14 hours+ (AnandTech, HTC official).
Is this typical or is there potentially a software or hardware issue?
I haven't done any serious tweaking to the software, and am running powersaver and have screen dimmed to 30%.
Thanks!
You have to see a lot of thing...
1) You had the full signal for all the calls?
2) Your phone was all time with the idle screen?
3) Did you have 3G or 4G on?
Details
I have three bars usually. I am always in 3G. As far as idle screen sometimes I am browsing while phone call is happening.
Does the strength of the signal effect talk time?
Strength of signal definitely affects the talk time. Also if you put the phone on 2g mode when you are not using data and just talking you will get a better battery life. Check for wakelocks as well. I also discovered when I was using htc sense launcher my app usage was about 89% but now I'm using smart launcher and my app usage is 70% and I'm getting better battery life. I've also disabled the maps coz it has a lot of wake locks.

Also, in my opinion, is the best phone I already had and I have been a iPhone fan for a longue time... With LTE one is very difficult to manage the battery for one day... If you can't charge during the day you are in trouble... Other complain I have is the high temperature on the back if i'm using for a longer time....

The tests for the timings are done with voice calls and no screen on. If your using the screen as well its double trouble

That's really low compared to yours. Also, using the speakers eat up a ton more battery, and if the screen is on as well, well that's another issue
I think I figured it out...
In case anyone else reads this thread, after some testing I think I found out what was causing the huge spike in voice app usage.
I now believe that playing music through the phones speakers counts toward the usage of the voice app.
When I use the speakers, huge battery drain. When I don't it's ok.
Hopefully case closed!

Battery lasts REALLY long at 1% battery life?

The other day I was trying to kill my battery, so I let a movie stream from Google Play until it died. It lasted TWO HOURS after the battery hit 1%. Yes, two hours of moving streaming on 1% of battery. See attached screenshot for proof (see the flat line at 1%).
Then, two days ago, I tested again. This time I just let it sit at 1% to see how long it would take to die. It took over 10 hours!! See other screenshot for proof.
Anybody else seeing anything similar? Clearly, when my battery says it is at 1%, it really has about 10-15% battery left.

Same here. I have a plug sitting here and the Moto X next to it and it's so routine to just plug in the GNEX, I want to do the same with the X but I don't have to.
I dont think this is necessarily a bug, I think it takes time for the OS to learn the full scope of the battery - it is always just estimating the charge. I bet after 6 months of use that 1% glitch would go away and you would see more accurate battery reporting. My phone appears to gain %'s when i leave it be after heavy use.

Yep same here, phone went from 4% to 7% yesterday when I was trying to make it last. I had turned off Mobile data at 1% battery life yesterday and my phone was dead within 25-30 minutes of being on 1%. I think everyones phone/battery is calibrated differently. With moderate use I'm down to 25-30% left after about 8-9 hours of use. Coming from my S4 I'm so used to being able to Greenify things, I can only imagine what this phone would be like with Greenify.

My phone is having this exact problem. I get about 10-12 hours battery life down to 1% battery, then it stays on 1% for at least 10-12 more hours. Does anyone know if there is going to be a fix released for this? It messes with my head not knowing when my phone is going to die, and I don't want to charge it if it's not dead. For instance, I'm on 2d 5h 14m on battery and it's been on 1% all day. It's pretty insane. Hope they roll out a fix. Glad to know i'm not the only one with this problem.
Next time this happens log your current and voltage readings using current widget so we can see what voltage the battery reads during this flat period at 1%. Then someone could plot the discharge curve in excel. May lead to clues. Perhaps problem with the fuel gauge or battery driver in the kernel. It all depends.
I seem to remember reading that the battery meter tunes itself over the first few charges, and that for the best accuracy you need to run it all the way down then charge it to 100%. 2-3 cycles of this is what was recommended. Can't speak to the validity of it but I know after running it down the first time and seeing the 1% last nearly 2 hours with heavy game use, on the second charge 1% meant 1%.

Idle drain still a problem?

Is idle drain still a problem after people have rooted and frozen bloat apps? Here is a screen shot of good idle drain from an HTC one mini. 3% in 9 hours.
When I had an X and a Droid Mini, they lost 10-15% in that same time period, despite showing 98% deep sleep in better battery stats. And they were setup exactly the same as the one mini.
Anybody with an X getting anything close to as good as what I posted?
And for those who want to say "who cares," the point is that idle drain overnight is indicative of idle drain during the day. Bad idle drain is a symptom of other problems and poor optimization by Motorola, imo, and it concerns me.
Sent from my HTC One mini
My idle drain is comparable to what you posted. I went to bed at about midnight with a full charge and now it's 7 and I'm at 98%.
I don't really notice it. I charge overnight and it lasts through the entire day and into the late evenings (8-11pm). When you're getting 5 hours of screen time, I think the optimization is working lol.

Are you seeing excessive idle drain? Metal head is about the only person I've seen posting good things about idle drain. I'm tempted to buy another X now that we have root, but seeing 15% drain in 8 or 9 hours of idle just bothers me to no end for some reason.

Also I would add that I think this problem affects most X owners, even though some (or most) will never notice. The battery threads show that pretty much EVERYBODY has higher than normal android OS use, due to the kernel according to gsam battery monitor. I think that is what's responsible for the drain, and personally I couldn't get it to go down even when I disabled everything. Android OS simply should not be the #2 battery drain behind screen, and it almost universally is on the X and the new Droids.

Are you seeing excessive idle drain? Metal head is about the only person I've seen posting good things about idle drain. I'm tempted to buy another X now that we have root, but seeing 15% drain in 8 or 9 hours of idle just bothers me to no end for some reason.

Nope, just always looking at finding better batt life. Last avg was 0.7% drain overnight. Just did a complete reinstall of the OS, root, and freeze. Going to see what happens tonight. Also hoping my moto assist starts working.
Is your wifi & mobile network access enabled under location access? That also causes drain, seemingly constantly. As far as I know, that is a bug with Google services and isn't unique to the X, but most prevalent in 4.2+ devices.

always. If I turn this off google now and anything else that needs GPS stops functioning. takes too long to get a gps lock without.

Could the highly varied battery life be a manufacturing issue?

Just throwing this out there... I have a Nexus 5 here has pretty poor battery, mostly when it comes to the screen time. Barely getting 2 hours per charge. In fact, I called google today and they are going to replace it; more on that in a bit.
I've tried stock, CM11, CM11 w/chaos kernel, paranoid w/franco kernel - neither is better than the other.. fter seeing some people on stock + franco and other combinations getting 6-7 hours of screen time it got me thinking. Could we be seeing a set of battery manufacturing defects? Google has already changed the speaker grill and button designs [ironically, my Nexus 5 that was ordered 1 week ago came w/the smaller speaker grill and loose buttons].
However, I'm wondering if there was a bad batch of batteries out there? If I didn't get an exchange from google I was going to pop this phone open and replace the battery with a new one just to prove a point. When I spoke to google today, they thought that a 20% drop in about 30 minutes of use was excessive, which I have to agree.
Ideas? Thoughts?

I'm repeating a post from the battery thread I just made....
[quote name="wdwms" post=51191930]I'm wondering if all the variances in battery life we are seeing could be a sign of a broader issue - a large batch of defective batteries?
opened this thread for thoughts/comments: http://forum.xda-developers.com/showthread.php?t=2686119[/QUOTE]
Nope. Its the variances in usage and settings. Guaranteed.
I got 6 hours screen time plus on my Moto x....always. with no changes whatsoever, my wife gets 4 1/2. Why? 90 percent of my use was tapatalk. Mostly just text. 90 percent of her use is Facebook, mostly images....with text. Images take more power to load than text.
That primary difference in our usage patterns made a consistent hour and half screen time difference. Oh....and she makes a few calls, I barely ever had or made calls.

Not meaning to debunk your theory....there are occasional defects....but mostly the huge differences are usage and settings.
The guys getting 6 hours plus screen time usually are running with most services off or frozen. Dim screens. Obviously not gaming much or at all. Not using location services or navigating. These things can make giant differences in battery life.
I suggest getting gsam. And doing a full discharge with it and doing some screen shots at the end. I'm betting if you think you have an issue that can be solved.....or its your particular usage patterns.

I can stand to have location services off for the hour of better SOT. However I can't stand having a dim screen so auto is the way I go! I still get 41/2 to 5 hours SOT!

I was using auto....and yeah, generally it's not to bad....now. I think 4.4.2 improved it....doesn't Jack up to full as much.
Then I saw someone mention "display brightness" app ....its awesome. A little slider always on my screen. Love it!

I get 6 hours screen on time on the reggie. Location left on (high accuracy) and same with Google now. I think the only things I have turned off in Google now are search history and location reporting. NFC off. Auto brightness. I agree with kj its based on your usage. I really only use my phone for tapatalk or texting mainly. Some Facebook (not really too into it) emails and a liiiitle bit of gaming.. I also use custom kernels and slightly undervolt. My phone can take -25 across the board and 675mV at 300mhz. I mostly UV for heating purposes when I game. (Addicted to robot unicorn attack 2 and smash it). Also don't use any kind of tap or swipe to wake (KILLS battery on this phone). Plus I always charge with USB. I read somewhere that lithium ion batteries discharge slower if they are charged with USB as opposed to AC. That and I don't have free A/C slots in my man cave. Just a USB port to from my PlayStation to a qi wireless charger. Yes it takes a while....
your battery life majorly depends on tbe quality of your phone/data connection. really majorly! it can make the difference of just 2-3 sot hours if not such a great signal is around, to 5-6 hours sot if there is a great phone/data signal. and it varies greatly for everyone. also, how you personally use your phone makes a large impact. its also going to vary greatly as we al use our phones differently. and how you set up your phone and which apps you use is going to majorly affect battery. and thats going to vary greatly as well. and there are even more reasons for the large variation in battery life.
Unless you heavily use GPS or voice calls, 2 hours SoT is too low. To get that you probably have a rogue processes preventing the phone from sleeping. In comparison, I've used the phone to game for over 3 hours on a charge.
Once that's out of the way and if you're still not happy with the battery life you're seeing ask yourself: what's running on my phone that I don't really need?
Every frivolous widget, forgotten service, or Google Now card is going to use some amount of battery and they add up on a limited power source.

That's a great point @simms22, don't think people factor into the equation quality of reception. In China on crappy HSPA+ with 1 bar, I'm lucky to get 3-4 SOT. In Los Angeles on an excellent LTE connection I can get 5-6 SOT. So reception adds 2 hrs of SOT in my case.
OP, as I suggested. Get gsam from play store....do a full 100 to very low discharge and lets see what it shows.
Otherwise we're all just guessing.

Started that last night, installed GSAM this am... 18h on battery so far, 48 minutes of screen time; i'm at 78%; Wifi has been on the whole time.. Stock build, rooted/bootloader unlocked; 2 gmail accounts, 1 exchange account (30 minute syncs).

Do a few screenshots when your battery is fairly low. Don't reboot or gsam resets.
For screens, try main gsam screen, app screen...then click the app screen dropdown, and do time held awake and kernel wakelocks. If you're not rooted, not sure which of these won't work.

My son played some games on the phone and i had to use the phone for work, so i need to restart the test.
Right now i'm at 1d 17h 40m, screentime 3h 28m; GPS off, google now off, hotword off, bluetooth off, wifi on, LTE.
Regardless, in gsam, the time held awake is
System 33s
Battery Monitor Widge Pro 29s
Google Play 18s
Android System 15s
Kernal Wakelogs
"no apps that have consumed the specified...."
I'm going to let the battery run out (at 6% right now); I've disabled wakelock for google play store in App ops; charge it up and then let it run w/out Wifi, and leave it on 3G.. My location is on the edge of LTE so its best to leave it on 3G here
Will post screenshots of that test when completed in the next 24-48hrs
Thoughts?

We can look at the screen shots still....but 1day 17hours with 3 and a half hours screen time? That sound pretty darn good to me! LOL
Guys getting 5 hours of screen time and that are usually near 24 hours, it much less. At a day and 17 hours....and that screen time, I'm doubting you have an issue at all.

Let me run a long discharge over the next day or so, and see where I stand.. i'm going to leave WiFi off, and 3G on (no LTE)

Keep in mind 3g uses the most battery for your internet condition. WiFi and LTE are more efficient though your low signal on LTE wouldn't help.

That is false. 3g uses less than LTE. Why do you think the Moto G gets such great battery life? LTE is a battery hog. WiFi uses the least power of the 3. Unless your 3g signal is very weak, it will conserve battery life over LTE.

It has been confirmed by users on XDA as well as this test.
http://anandtech.com/show/7517/google-nexus-5-review/3
N5 LTE is more efficient than previous LTE phones due to some Qualcomm tech. Also by being considerably faster than 3G it can finish its task and go idle quicker.
Moto G battery life is mainly due to its considerably less powerful specifications.
