Hi,
I normally have excellent moto g battery life. However four times I have noticed a bad battery drain. This seems to occur when I switch from one wifi network to another. Here is what happens:
1. On home wifi with battery drain of maybe 1% an hour (at most) when phone is idle (not aeroplane mode - just sitting on table with wifi active).
2. Move to a new location for an hour and use wifi.
3. Get back home and phone now drops 3% an hour when idle.
4. Even more odd - if I switch on aeroplane mode, so wifi is off, the phone still drains 3% an hour. Normally I see at most 1% drain a night on aeroplane mode.
I used 'wakelock detector' app and there are no wakelocks above what I normally see when battery is normal.
The standard battery graph shows no obvious apps as the cause, in actual fact when I put it in aeroplane mode it shows just blank lines for gps/wifi/screen/awake etc. So all looks normal for aeroplanoe mode, ie nothing is awake.
cpuspy app shows phone cpu goes into deepsleep mode (ie cpu sleeps).#
Only way to fix issue is to reboot.
All I can think is that the phone is trying to connect to the wifi network it has just left, eg when I go from home to a new location it connects to the new location BUT is still trying to connect to home as well, and when I get home it connects but is still trying to connect to the previous location.
However that doesnt explain why I still get the battery drain on aeroplane as wifi is off mode unless something is 'stuck' but not showing up in any statistics.
Any ideas? Ive pretty much exhausted anything I can think of. Phone isnt hot at all so its not the CPU (cpuspy shows deepsleep as well remember).
Ive just factory reset so I will be able to see in a few says if it still happens but Im pretty sure it will. Im hoping its a 4.3 thing and that 4.4.2 will fix it but I also think it may be hardware related, eg wifi chip doing something weird, in which case 4.4.2 isnt gonna help.
Regards,
Scott
My wifi was draining my battery also. I see in settings under wifi it is set to always remain on even when screen is off. That was keeping my phone awake for hours. I switched wifi off and not had a problem since.

Thanks for the reply. Not the same issue as me though. I do have 'WiFi when sleep' on when at home but normally that's OK for battery as I have excellent WiFi connectivity at home.

Got the same issue! No wakelocks, phone asleep, steady drain in airplane mode. Only change is I've gone to my parents for Christmas - signed into their wifi of course while I'm here.
Maybe a bug in the WiFi driver. Good to know a reboot fixes it temporarily, I've just restarted my phone after fully charging it and will see if it's behaving now.

Hi, keep me up to date on how it goes. I'm thinking not a 4.3 issue or it would be more widespread, not an app issue as no wakelocks. Must be driver type issue as you say. Pray its not hardware itself.
I'm running British retail ROM, what are you on.

I factory reset and reinstalled apps. My problem described above seems fixed but too early to tell for sure.
However before I reset I noticed while the drain occurred that an app called 'cpuspy plus' was behaving strange, eg it showed 30 processes in osmonitor and each process was using 0bytes of memory, and I also had hardly any spare RAM (normally 250MB free but it was down to 70MB or so).
I don't know if the factory reset itself fixed the issue or if removing cpuspy plus fixed it.
I'm guessing the factory reset did it but I'd be interested to know if you are using cpuspy plus.

Well, I had a 10% battery drain overnight (7 hours) in airplane mode... I was in my gf's parent's home and used their wifi network.
Now I did a factory reset and I'm charging the moto g again. Hope that fixes it, I'll report back when I know.
Experiencing the same problem. Not sure of the cause.
I think it is the option "Scanning always available" in the advanced wifi options

I have the same problem. I'm on 4.4.2 without root. My wifi stays on all the time since I learned that wifi uses less battery than 3G or 2G (am I right?). Also the wifi-optimisation is activated. Strange thing that happens in airplane mode.
Can someone pls report back if the issue is solved by a factory reset?

I've been having this issue too, on 4.4.2 US GSM. I went from draining 1% overnight to draining about 2-3% per hour on standby. Couldn't figure out why for the life of me either. Its been this way for about a week now, I've tried rebooting but it doesn't seem to help.

I am on an unrooted 4.4.2 US GSM and have a similar problem. I've noticed an average of 1.5%/hr discharge overnight with mobile data, and wifi shut off. I'm gonna put it in actual airplane mode tonight and see how it is in the morning. I did some tests during the day and saw that the phone was awake with the screen off for ~8% of the time (used better battery stats).
Unfortunately, with the retarded kit kat battery permissions - we can't see exactly which process is the culprit for the wakelocks - just the "catchall" power manager wakelock.

Have you factory reset yet. If not then do so as it fixed it for me and others (that's if its the same issue).

When I first noticed this happening, I reflashed the stock image, but it hasnt made any difference. I'll give the factory reset a go & see if that helps any.

Put it in airplane mode all night and had location services disabled. Here's the result, still 1%/hr drain.

Maybe someone will notice .. I'm thinking of downgrading to 4.3 somehow, so I can observe partial wakelocks and figure out the root cause.
I get battery draining without wakelocks. I think it's my network since airplane mode has none... Nothing I can do.

I've had my skyrocket for about a month now, and I've had horrible horrible battery life compared to all of you guys on here. I've tried reflashing, did the whole .3e recovery/ wipe/ fresh install tutorial that Seanz posted. (Amazing rom by the way.)
Nothing seems to work. I've calibrated my battery at least 4 different times. Oh, and for Seanz, You say your rom is 2.3.5, but in my settings it says 2.3.6. My brightness is all the way down, My data, bluetooth, gps, etc are ALL OFF! Only thing I keep on is wifi, ALWAYS. I've tried leaving my phone off the charger all night and locked to see if the drain was the same, and it is, If not just a tad less drain. I'm sorry if I didn't clarify this good enough, If someone could help me out I'd be glad to explain myself better!
Does your phone maintain a strong to moderate signal (both data and talk)? This includes the strength of your WiFi connection. I've noticed one of the biggest (if not the biggest) drain on this phone and most others comes when the phone is strugling for a decent connection. If you can, try this: put your phone in "Airplane" mode for 1 charging cycle. This means your phone won't even try to get a wireless connection of any type. To be safe, make sure the "WiFi" is off as well. See how long the battery lasts compared to it not being in "Airplane" mode. If it still sucks, you might need to see which app(s) are draining your phone. If it is noticably different, a weak signal might be the problem. Good luck.

He changed it only in text for certain apps that require Android 2.3.6, even though they'd work completely fine on 2.3.5. Somewhat an easy workaround. Also took some of the features from 2.3.6 in. It's still built from 2.3.5 though.

Thiiiis is probably your big issue. If you have any apps running in the background that use data, they can keep the wifi awake, which, in turn, never lets your phone sleep. If you go to Settings>Wireless and network>Wi-fi Settings>Menu Button>Wi-Fi Sleep Policy, and set it to "When screen is off," you'll be AMAZED at how much life it can save. I've noticed drastic differences when that setting is applied. As far as without it losing around 10-15% overnight to a mere 1%.
Thanks for your replies! I'll try you guys' ideas out now. I seem to lose about 1-3 percent every 10 minutes. I'll put it in airplane mode and try it for an hour.
Thank you Fortune! was wondering how to do this, You could have just solved my problem. I'll keep you guys informed! I'm amazed at this communities helpfulness. Thank you!
No prob!
Though, next time, if you have a question, should post it in the Q&A section of this forum. People tend to get a bit pissy about seeing Q's posted in other places, haha. Just giving a heads up!
Hope those fixes fix your battery life! That wifi sleep on has been key for my 30+ hr battery lives on SkyICS.
Seemed to not help :| Since I've done this, It's gone from 22% to 17% in about 15-20 minutes. No apps running, etc.
Try downloading CPU Spy from the market place and after awhile of letting it rest (about an hour or so), open it, refresh and check to see the CPU uses the "Deep Sleep" frequency at all and to see which frequencies it spends most of its time in.
Also wouldn't hurt to check Settings>About Phone>Battery Use to see what's using most of your battery life. Display, Android System, and Android OS typically hold the top 3 spots, so if anything is up there (or at a close 4th), that app could be what's bogging it down.
I downloaded CPU Spy and it seemed to already have data for it and it says 4% in deep sleep, 65% in 38 mhz, 5% in 810 MHz, and 1% in 1026 mhz, 17% in 1728 MHz

Alright, well so far so good. Shows it's at least getting some deep sleep and able to idle in low frequencies. Can't really get TOO well of a reading until it's done some time with it idling though.
Do not set wifi policy to screen off, keep it at always. this will keep your data using wifi when connected which is way less of a drain than the 4g radio. Basically with the screen off policy your phone will still use data, it will just come from cellular instead of wifi when screen is off.
Also get this

It will tell you what is running constantly and draining your battery.

Since he has his data off, turning off the wifi with screen off will benefit him greatly. It would be stuck on otherwise. Noted:

Ohwow.... That's....... Interesting, haha. If I notice my wifi is on for extended periods of time, my battery starts draining a bit faster than normal.
Might have some app in his background either keeping the phone awake or just hogging background data, keeping the wifi constantly active.

the real issue is when i actually stop being on wifi. when my phone uses data connection, mostly LTE because its everywhere around me, the battery life becomes miserable. I left the house for about 1 hour today, you can clearly see it on the graph. I should try to cut all connectivity and just allow the phone to sync every now and then, im sure ill be able to add another half a day at least to my already 1.5 days with wifi on all the time

Yeah, data is a KILLER. For me, it's usually wifi or nothing, unless I'm trying to send or receive an MMS, or need to quickly access the Internet, but I turn it back off as soon as I'm done, and I set my network to no LTE because it's not in my area.
Just take that as a note OP, lol.

Sorry, I've experienced the opposite since my upgrade. Great battery life for me. Not sure you are seeing a 4.4.2 issue.
Did you go to stock 4.4.2 from a custom rom, without wiping data?
I went from custom 4.4 to 4.4.1, dirty-flashed. When I went to 4.4.2 it *****ed at me about wiping data and then **** started to break.
After factory reset, mine's been utterly golden. 76%, 5 hours on battery and most of my use is the screen and occasional game played.
Completely stock, not even root.
Yesterday, I was at 49% after 12 hours, on wifi all day, streaming a couple of hours of audiobook via bluetooth during commute.
That's the kind of performance you should be seeing on proper stock 4.4.2. Only thing I could suggest would be to factory wipe, reinstall the base 4.4 image and update from the OTA.

I flashed stock using the factory image. I then sideloaded the 4.4.2 update. Configured the usual settings, nothing fancy or out of the ordinary.
Couldn't be more stock than this (minus the root for BBS).

It's been garbage. I'm having notification issues also. Will most likely revert to 4.4.
bam_dmux wakelock and powermanagementservices_wakelock are the big culprits. Your wakelocks drained your battery 33% in 2 hours. Could be a radio issue.Should be the .23 baseband installed on 4.2.2.
Will people stop quoting the 3 enormous images from the original post? He knows you are responding to him as its his thread.
I see at least half of your problem is the wlan_rx_wake bug that I and many others have been experiencing. There is no fix for this so far that I have found.

just cause its constantly using your mobile data doesnt mean its pulling down big files or anything like that. something is just waking up your phone mobile data using it, and not letting your phone idle.

It is not normal for wifi to keep a device awake when the screen is off and nothing is happening on the phone. My router keeps my phone awake for hours a day. No other phone I have ever had has had this problem. Its a Kit Kat problem.

Thanks for the help thus far. I will flash stock image again. Root for BBS and see what happens under 4.4. If all goes well I will sideload 4.4.2 again and post the results.
Battery life was great under 4.4 for me... but I really want the improvements to the camera in 4.4.2
Flashed back to stock. Didn't update to 4.4.2. I just lost 17% in 24 minutes. I am not even rooted. I
Did not even configure anything. Just flashed, logged into my Google account and watched it drain.
Screen has been on all the time under auto brightness but it should in no way consume that much power.
Thoughts ? Thanks
(Edit) 22 minutes out of 27 using the screen. Went from 50% to 31%.
(Edit) Tried airplane mode with screen turned off. Lost 2-3% in 6-7 minutes.

Hi I have a just got a MAXX and updated to 4.4 without root. I found that my battery is not staying up as long as it should, it lasts for like 18 hours. The following are the details:
- Canadian user, Fido sim card, exceptionally bad reception (3 bars tops indoors) (My Phonto Q / Razr Maxx gets full bar when I plug in the same sim card)
- Screen On time at about 3-4 hours
- Rarely turn on data
- Rarely Game on Phone
- Non-rooted
- I keep wifi turned on, connected most of the time
- Use apex launcher instead of MotLauncher
- Active Display, Touchless Control on
- Location Services are in "Battery Saving Mode" (Meaning the phone uses wifi and mobile network to estimate location)
Is anyone else experiencing the same problem? If so, is there any solution? I see a similar thread made early but that is for the Ultra, and even the ultra got around 12 hours of discharge time
Edit: So far based on doogald 's reply, I suspect its the poor reception thats draining the battery, the following photos shows the reception differences across different devices with the same sim card

How long have you had 4.4? When I have updated or changed ROMs, it seems that it takes the software a little bit of time to catch up getting to know the battery.

That's a little more drain than I would see for the same screen on time. Bad signal will definitely drain a battery faster. Forget about stupid bars - what is your signal in dBm? (Settings->more (under Wireless & Networks)->Mobile networks->Network type & strength. Also in settings->about phone->Status->Network type & strength).
The number will be negative. For GSM or CDMA, anything less than (more negative) than -100 dBm is a bad signal and the phone will amp up the antenna to try to pull in signal.
Based on your battery screenshots, though, it's probably not bad signal - I think "cell standby" would be a higher drain if that was the case.

I have had 4.4 for exactly 10 days now, i think everything should be settled by now
My signal is around -97dBm, and it jumps from that to No Service. I dont understand why this phone have such terrible reception though. I had two other phones try the same sim card and they have excellent reception.

Question- are you rooted and using xposed framework? Things that heavily mod the stock system, like GravityBox or Xblast can easily have that affect. Even smaller things like the smooth progress bar can hit it. The more changes, the harder the system has to work to keep up

I have terrible reception at home and work and am getting 7 or so hours of screen on time. Constant switching between 4g/3g and sometimes to 2g.
I'd suggest trying a program like betterbatterystats or similar to see if there's a wakelock keeping the phone from going into deep sleep mode (processor shuts off) when the display is turned off. Also cpuspy will show you if it's deep sleeping. It won't deep sleep while charging btw, this is normal.
For me the problem was the Facebook app. I disabled it and not only did my battery life significantly improve, but so did my productivity Info about wakelocks, if you're interested - http://developer.android.com/reference/android/os/PowerManager.html
Pain in the butt but there's always the factory reset option too.

Not sure why this worked, but it did. At least through one day of testing
I ready elsewhere on Droid X forum someplace I think about draining the battery completely until your phone shuts off and then recharging. It's supposed to re-calibrate it. Sounds sketchy at best I know, but it seems to have worked!
I did this with my ultra followed by charging to full and did a factory reset. My phone seems to be normal again.

Hey everyone, on my Nexus 5 32GB on airplane mode, using greenify, brightness all the way down most of the time, some music, and on WiFi some, on Instagram or Kik messenger, I get about on average 2 and a half at best screen on time. I'm running my phone completely stock, and switched to ART recently, (it was the same on Dalvik too) and actually noticed an improvement speed wise, but I feel my battery took a hit. It drains a percent every minute or so when I'm on it, and I'm constantly pulling it down with two fingers to see my battery stats. I see people getting 5+ screen on time, and I just do not get it. I'm on airplane mode and everything.
The two biggest battery consumers are Android system and Android OS. With Play Music following and usually screen on time. I'm on complete stick 4.4.4. KitKat, no extra XPosed, no GB, no kernels
Is my battery just really bad...? I unplug from charger at about 6:40 every morning and by 4:30 every evening, I have about 50 percent if I really try staying off. Maybe an hour or half SOT.

Disagree when the user stated he was in airplane mode but it was a tongue-in-cheek comment anyway.
It's probably just your work signal. Most work buildings tend to get bad signal, and that makes any usage and background drains go up exponentially.
My battery expectancy is cut in half at work, even though I tend to use it less.
Thanks for the speedy replies everyone. I updated my OP I get off the charger at 6:40 and at about 4:30 I get home with 50 percent battery, mahnr an hour and a half at best screen on time. On FB or IG or Chrome, it gets warm I noticed. Then by about 6 with minimal use its usually needing a charge at about 20-30 percent. On airplane mode all day, only using WiFi and turning it off when I ain't on my phone.
With out any mods/kernels 2.5-3 is the norm. Just flash a kernel. You'll have AMAZING battery life.

And I'm a heavy user.
I don't have Greenify, or put phone in airplane mode or anything of that sort.
That's straight one day usage with lots of YouTube, Instagram, Play Music and Reddit. Lots of reddit.
I have not done any modifications to my Nexus 5, and I'm averaging about 4 - 4:15 hours per day since I got it this past Friday (so 4 days ago). I doubt I could get it to 5 hours without a custom kernel or ROM. Maybe if I had the lowest brightness set all the time, and stayed on strictly Wifi.

What kernel are you using? I tried Franco before but had lag in Asphalt 8 and switched to ElementalX but didn't notice any improvements. That was when I was on 4.4.2 and got the OTA to 4.4.3. I installed 4.4.4 manually because I didn't want to wait.
Some people seem to get 5 or 4 hours SOT but others they get 2-3. It's weird really.

Not everyone can get 5 hours. Things like signal take a big impact. Kernel won't help that.
Pretty much any kernel can be tweaked for battery or performance. Its all in the governor settings. There's no kernel x is better than kernel y when it comes to battery life. Its just some people think this because of the kernels out-of-the-box config
Learn to tweak governor settings, but you still may never get 5 hours screen

So with airplane mode battery should be on my side? What governor settings would you recommend? I know about the settings already a bit, used my Inspire 4G with a handful of custom Roms and I used I think it was smartassv2?
Read first 4 posts. The more of the stuff in there you do... The better your screen time will get.
Though a bad signal on data is the silent killer as others said. Airplane mode is overkill though, usually. Just disable data when in bad areas.

I have my phone in airplane mode 24/7 for now, my SIM is in another device atm for me to play with. My Nexus 5 is my primary device. Since I have zero service in or out, I have airplane mode activated. Data and everything should be killed when its active, right? I know the usual radio drain on the battery, but it isn't in my battery information because airplane mode.

do you have scanning always enabled disabled in your wifi settings?
i didnt see your battery stats, if you posted(quick glance). anyways, its not about kernels, as most have said. i get 5 hours sot nearly every cycle. battery is about how you use your device, how you set it up, what apps you use, and most importantly, the quality of your phone and data connection. and ill tell you what, brightness makes a huge difference. ill get an hour less sot if i keep my brightness at 50%, than at my normal 20%.

well, we can see the "always scanning" in the battery atats. it shows up as wifi on in the battery stats. if you have always scanning enabled, and turn airplane mode on, youll see if it gets disabled or not in the battery stats.

That's a good question. ☺
I don't know either, I never have always scanning enabled.
I'd like to think it is off too... But maybe not.
I'm experiencing unusually high battery drain during idle time (screen off), when the phone should deep sleep but instead it remains awake. I'm using the same set of apps I used on my last phone (HTC One M7) so I doubt any of them are the issue. Could tap to wake, smart connect or something else be causing this problem? Please advise.

Understood. I could just switch to wifi calling and the network won't be used whenever on wifi. This presents another issue. This phone keeps dropping wifi connection and then reconnects. I wouldn't be surprised if this happens all night. I bet that's a major reason for the idle drain too. It didn't happen on my old phone with the same networks and work areas. What can I do about it?

Did you use any wifi booster apps? Or, can your phone adjust the time of network scan? I mean setting of period to rescan network? Did you try your battery perform without any network connection?

I don't use any Wifi booster apps. In fact, I switched from cellular to Wifi calling and still having the unusual battery drain!
For me the same problem occurred when I was in a shopping mall that had poor signals. My battery dropped like from 63% to 15% in less than 2 hours. I checked the battery usage and mobile signal is the one draining it all. After reaching home and charging it, everything worked fine.
