Yes, it's supposed to solve the GPS issue, but for users that never use the GPS it's not exactly a good feature. For example, I very rarely use Maps, but when I do I just use mobile triangulation. Because of rarely using it, having WiFi enabled in the background all the time isn't necessarily appealing to me, and I'm sure this is true for many other users too.
[Nexus 5 General] Greg Tolan:
If you have your location settings set to battery saving and not high accuracy the GPS chip should never turn on. So in that scenario, having WiFi scanning always available isn't smart as the GPS chip isn't going to turn on as an alternative.
[Nexus 5 General] jdawg0024:
Ok So after the Factory reset I was at home all day yesterday, except when I had to take the dog to the Vet and I got great battery. over 14 hours with still 60% when I went to sleep. I get 2-3 bars of signal at home and I was on WiFi all day. (didn't turn it off while at the Vet either). I go back to work on Saturday so I will report my battery results on Sunday to see if it is indeed having little to no signal that kills the phone quickly.
[Nexus 5 General] whitedragonz83:
The combination of the Nexus 5 and my home wireless router have a compatibility issue it appears. AndroidOS with high wakelock, no apps cause it. Turn WiFi off (leave background scanning on) and everything is great again and my device can go into Deep Sleep just fine (>=90%).

I changed Beacon Interval from 100 to 50 and DTIM from 1 to 20. Fixed everything for the first night of testing immediately. We'll see how night #2 goes.

GPS battery usage > WiFi Battery usage. It's smarter to go into battery saving mode (note how it is actually called the battery savings mode), to be more power efficient. Your accuracy and location will suffer a little (or lag behind) and any GPS app like Google Maps will not really work well.

Here is a good (oldish) link showing more about power usage with WiFi/GPS:

Maybe I shouldn't update to 4.4.2 with all these battery problems
[Nexus 5 General] mattcoz:
The keyboard is definitely louder, annoyingly louder.
[Nexus 5 General] joe.attaboy:
You can turn off Google Now's listening in the stock launcher.

On the Google Cards page, scroll all the way down, open the menu, Settings -> Voice -> turn Hotword Detection off (unckeck it).

The voice search will still work. Just touch the mic icon on the search bar and start talking.

I'm a relatively light user, but my batter life has been awesome since 4.2.2. I never got 4.4.1, as the update game out before it hit my device.

I had the phone off the charger about 30 minutes after 4.4.2 installed. I plugged it back in 28 hours later and still had a bit over 30% of the battery left. A few phone calls, a bunch of texts, some browsing at dinner. I'm on wi-fi at work and at home. LTE elsewhere, pretty good voice signal everywhere.
[Nexus 5 General] whitedragonz83:
No real indication most of these are related to 4.4.2. There are a lot of bug fixes too in the patch and a lower overall memory footprint.

---------- Post added at 01:11 PM ---------- Previous post was at 01:09 PM ----------

Lux is awesome. As a person above mentioned, you can turn off active listening. It also only occurs when you are on the home screen. How long are you staring at it? Likely not enough to be a big battery hit.

---------- Post added at 01:17 PM ---------- Previous post was at 01:11 PM ----------

Barely. You are only relaying on Cell Towers at that point with Battery Mode and Wi-Fi scanning off(and WiFi off). GPS wouldn't trigger regardless under Battery Mode.
[Nexus 5 General] Greg Tolan:
Exactly my point. No GPS and No wifi scanning = Battery Savings.
[Nexus 5 General] 0b095:
I am also suffering from bad battery life on 4.4.2. Screen time on is 1h 30m, and battery level is 14%, and I am not a power-user. It used to last 1 day at least with a 3-4h screen time on.

My settings :

location off

google search is disabled.

display brightness mostly on half or top.
[Nexus 5 General] whitedragonz83:
GPS off + Device Mode = better battery savings in that regard, or just location off completely.

;)

---------- Post added at 01:39 PM ---------- Previous post was at 01:38 PM ----------

Location and GSearch don't take that much battery. Check mobile signal, see if an app was recently updated, check Settings->Battery.

I do not know what you mean by "display brightness mostly on half or top"
[Nexus 5 General] nikos k:
After update. The battery is bad..:eek:
[Nexus 5 General] raffstyle:
This is BS!! after upgrading to 4.4.2 my battery is WORST than ever!... when i was still at 4.4 my battery was good. i updated yesterday noon. i charge my phone up to 80% then unplugged it around 4:30pm at 11PM im at 10% my screen time was less then 2hrs.

also if this affect my network signal, i always have at least 2 bars of LTE every time im at my son schools parking lot. now its switching from 3G to H.

I drain my battery last night then charge it over night, off the charger 10:30am loose 10% in less then an hour!

DO factory reseting will help? thanks!!!
[Nexus 5 General] Greg Tolan:
Touche!
[Nexus 5 General] whitedragonz83:
If you believe the radio update made your battery worse, a Factory Reset will help as long as you don't update to 4.4.1 or 4.4.2. Otherwise, Factory Reseting is a waste of time if you plan to update back to 4.4.2.
[Nexus 5 General] raffstyle:
Im already at 4.4.2 coming from 4.4

Do factory reset will help me with battery problem?

thnks!
[Nexus 5 General] whitedragonz83:
Read what I wrote. I explained clearly the case how a Factory Reset would help and how it would not.
[Nexus 5 General] TheIgster:
Part of the functionality of the Nexus 5 and KitKat is having things like Google Now there easily with a swipe to the left and having that functionality. Turning things like Google Now off seem silly and turn your smartphone into a dumbphone IMO.

I have not changed anything and my battery life was awesome on 4.4. Now, on 4.4.1 and then 4.4.2, battery life has drastically dropped. Something else is causing the issue since the update.
[Nexus 5 General] 0b095:
I do not have a sim card, so no mobile signal at all:) when I check settings, I see screen 22%, a few games totally 21%, Google Search 20% (eventhough I force stopped this:S), BeautifulWidgets 16%(I only use clock+weather widget on my desktop, and I have never seen this app under Settings->Battery before 4.2.2. update.), and android system, wifi, phoneidle,android os , etc at %19 total... I use the phone screen bright so I do not often dim it.
[Nexus 5 General] jamezz23:
Complete bs. The battery life before update was half way decent. Barely used my phone today and I'm at 23%... Normally at 70 but 50% at the absolutely lowest... And instagram isn't the drainer, it's just the only appy I really used today, **** this update..
[Nexus 5 General] NoelOnyx:
Same issue for me. I had my Nexus 5 for a few days, everything was fine, and yesterday it updated to 4.4.2, now I have "Android OS" using more than 50% of my battery.

From 100% to 1% : "Android OS" on top of battery usage with 50%, followed by the screen with only 15% and then a game with 10%...

I was at home the whole day, wifi on, which used to end up with an at least 60% full battery. :(
[Nexus 5 General] Knight-Rider:
If you're rooted with custom ROM use Battery Calibration every time you flash a new ROM once your battery level has hit 100%. I've also been doing this since the early S2 days, I edit the build.prop file in /system and add the below 2 lines. This causes your phone to go into deep sleep mode when screen is off. My battery last me anywhere between 20-22 hrs on medium use with 30-40% screen time it varies.

add the below two lines as is after the last line in build.prop file, I use root explorer, create a copy of original and move to sd card and edit there. Rename the original build.prop file example add .bak at the end of file name and than paste/move modded file back to /system and change permissions and change owner, again I use root explorer. PLEASE MAKE SURE YOU ALWAYS BACKUP.

Did you take photos with Instagram? Camera battery drain increased with the psych.
[Nexus 5 General] jamezz23:
Nope I was just looking around. But it makes a little sense, cause I think instagram might run the camera in the background cause all I have to click is a tab and the camera is already open. So you might be on to something. I'll uninstall it and test the battery out tomorrow! Thanks for the help!
[Nexus 5 General] bblzd:
This is true and most location stuff seems to still work fine. I guess it's only using cell towers at that point if your WiFi is off. GPS even disappears from your battery graph as it never get's pegged using Battery Saver.
[Nexus 5 General] chk27:
mine too, lost about 40% of battery use time from 4.4 to 4.4.2, can't say on 4.4.1 because i've had it for one full day only.
[Nexus 5 General] rabaker07:
I left the house at 8 at 99%. Was shocked that I'd been screen on with music and what not for 15 mins on train and still at 95%. Some photos and videos and phone calls and a few beers later and by 2:30am the thing was dead.

6 hours till dead? I couldn't even check my SOT.

How does the Moto X do it? The battery isn't much different. And don't say AMOLED blah blah blah because my GNex had all that going for it and that thing died even faster than this. I should sideload 4.4.2 on that device and see how it fares...
[Nexus 5 General] krips2003:
After reading all these stories about bad battery life on 4.4.2, I didn't install the OTA. But then I decided to install it. As of now I might be three lucky one who's battery life is either improved or its as good as I had on previous version. FYI... I'm running ART though.
[Nexus 5 General] whitedragonz83:

[Nexus 5 General] kayone73:
Fortunately I'm not having that problem:

I finally hit a sweet spot in battery life on the N5 after making some settings adjustments: Currently running latest version of Cataclysm rom (Android 4.4.2) with it's Smart Radio feature turned on, set selective wifi scanning when wifi is on, partially disabled location services restricting it to GPS only, turning it on as needed to mobile networks when using apps like yelp, and running faux kernel with a global undervolt of -50

This was an average use day mostly texting, a couple short calls, web browsing, a lot of music playing, both web streaming and off the phone memory, a few photos, didn't really play videos or games.

Could have easily broken 24h, maybe 25h if I wasn't monkeying around with the phone during it's last hr.
[Nexus 5 General] 20mark:
I am having the android system drain too. running cataclysm 4.4.2.

yesterday no problem,drainage was pretty normal with 0,5/1 % per hour in standby ,

but today in less than 3 hours i've lost 15 % battery. so bad.

i think this drainage its not rom'fault, as there are people with stock rom who experience drain too,and the rom who im on cataclysm was sweet in terms of battery drain yesterday ,so i was digging more and more on the web searching for the temporary solution till google fix this nasty bug.

so i found this recommendation:

when you unplug your phone when in charge unplug with screen turned ON .

this seems to fix android system wakelock.

i have not tried this yet as i found this today, tomorrow i'll try this and report.
[Nexus 5 General] jjjooonnn:
I'm on Cyanogen and every time I look at the battery it seems to tick one percentage less than the last time I check. Still get me through the day, but it does seem to drain faster.
[Nexus 5 General] gaurishmhatre:
battery life after update sucks :(

has anybody tried to go back to factory version 4.4?

i had amazing battery life on 4.4 but it drains much quickly. battery life is almost half after update.

i am thinking of going back to 4.4 as i can bear with the camera. what would u guys suggest?
[Nexus 5 General] mgerbasio:
I'm seeing the battery drain to be higher and somewhat more erratic than before the last upgrade. I think it just needs to go through a few charge cycles. I notice, using the Google Nexus Qi Charger, the phone takes much longer to charge too.
[Nexus 5 General] TurkzZ:
im experiencing more battery drain too, seems to drain away allot whilst on stand-by, previous versions used to lose next to nothing during stand-by ...
[Nexus 5 General] illhangon:
Have you guys tried turning off "Back up my data" under "Backup and reset"?

It did the trick for me.
[Nexus 5 General] whitedragonz83:
I've done some more testing in safe mode. Can't make Android OS go crazy on Wi-Fi. Leaning towards an app even though better battery stats don't tell me what it is. Anyone having issues should start with safe mode and see if the problem exists.
[Nexus 5 General] ravenwood27:
4.4.2.

Unrooted, everything stock. Pretty much mostly stock google apps. Twitter, Snapspeed, candy crush....that's it.

Drains quite fast. IT's a bug definitely.

Hope 4.4.3 fixes it.
[Nexus 5 General] FirePoncho86:
I flashed Cataclysm 4.4.2 and my batter is pretty solid.

Studying for finals so naturally a lot of reddit and Facebook messenger use. WiFi only. Some light gaming, couple of youtube videos, some pictures taken. Medium-heavy use I'd say. 6.5 hours of screen on time pretty solid! I am coming from a nexus s so this is pretty much doubling what I used to get. When my screen was off, my phone slept like a baby. I do have Gnow on!

Performing the switch from ART to dalvik and then back to ART fixed my battery drain. I am running stock everything, and OTA'd the updated.

Back to getting Great Battery on 4.4.2

As I stated in an earlier post that ever since I updated to 4.4.2 (from 4.4.1) My phone was draining really fast when I was at work (where I have horrible signal, but was on WiFi). I did a factory reset of my phone 2 days ago and today was my 1st day back. Here are some screenshots of the Battery while at work. I can say that it is back to having excellent battery life. I don't know if doing a factory reset fixed what was wrong or it was something Google Fixed on their end. Besides the factory reset I also "forgot" both my WiFi at home and at Work. I am also using Dalvik. I am going to switch back to ART and will keep this thread updated.
[Nexus 5 General] cbatiste1993:
I don't have a Nexus 5 (til Christmas) but I wonder if the different builds coincide to which have battery drains and which ones don't. If you have the battery drain bug do you have build 310 or 311? The issue could just be hit or miss but it's worth a shot to fire out a theory right? :p
[Nexus 5 General] jdawg0024:
I have a 310 which had the issue until recently. I did a factory reset and all is well. My Roommate has a 310 which never had the issue. Both phones are on the Sprint Network.
[Nexus 5 General] 20mark:
not yet but you can try yourself and post results
[Nexus 5 General] muEcke*:
I had the same issue and tried to find the problem for hours... but I didn't have success. Restoring with factory image did the trick for me and the problem never occurred again...
[Nexus 5 General] andQlimax:
If you use Twitter swipe it away after use, in some random conditions it start using cpu like hell without stop

Some other apps do the same, that could be the problem for some people

My battery life on stock 4.4.2 is perfect.. Always reach 4.30h screen on time each day

Anyone with poor battery in Wi-Fi have either Newegg or a Best Buy app installed? "High Android OS".
[Nexus 5 General] Krzysiek_CK:
At first 4.4.2 was draining the battery normally for me. Then all of the sudden it started to drain like crazy, and Android OS got on top of the list. I traced back my last changes and looks like Data roaming, under Settings > More... > Mobile networks if the guilty party. I unchecked it back and so far the batter drains much slower when phone is not used. In next few days I will know for sure.
[Nexus 5 General] whitedragonz83:
It wasn't the 2 apps apparently Android OS randomly goes dumb. I did find very high Google Music download when I never used Google Music today.
[Nexus 5 General] ravenwood27:
what do you mean "swipe it away" ?

From the task switcher ? ...That actually kills apps ?? I thought it was just good at switching apps and that swiping stuff is only for neatness..since google don't recommend killing apps.
[Nexus 5 General] charmcitybryan:
This worked for me

Like most in this thread, battery life went to crap after update to 4.4.2. Went from about 1% drain per hour under normal use to about 5%. I tried just about everything on this thread from messing with the location services, wi-fi settings, Greenify, different kernels, even tried a secret blend of cajun seasonings.

Though some of these fixes made things better, none got it back to original drain levels. Last night, I tried a factory re-set and we are back in business with 1% battery drain looking good once again. One piece of feedback I will give is that a few things suggested in this thread have actually made a positive difference and made performance a touch better even than they were. First big improvement was Greenify (donation version). Definitely worth it. Second was moving to Franco Kernel. Tried stock, Chaos, and Franco and seem to be getting best results from Franco. Third was moving Wifi back to "Keep Wif- always available- Always" checking scanning always available, and checking Wi-Fi optimization.

As always your results may vary, but wanted to share my results as this was a big pain in the bum for about a week.

Interesting. I updated to 4.4.2 by flashing the factory image. So a complete wipe, in effect. I have been getting excellent battery life. Except for the one time I had no cell signal. Then it took a really bad hit.
[Nexus 5 General] whitedragonz83:
I hate the thought only factory reset can fix this. I'll try it though later as I'm getting sad that the same apps on my nexus 4 didn't cause this problem.
[Nexus 5 General] jdawg0024:
It sucks, but I had to do it and it fixed everything. Also I think that some how the ota didn't get installed properly and that's what messed everything all up.
[Nexus 5 General] testinguser:
I believe factory reset is indeed the fix as cpu-z now shows the cpu utilization dip below the full 2.27 ghz, though only momentarily. So far I am down to 84% on 4hours with android OS taking the biggest chunk of battery usage though after the factory reset I had to setup everything so perhaps that is the reason -- or wishful thinking we shall see
[Nexus 5 General] jdawg0024:
After I did my Factory Reset the battery was still not that great. However after a Full charge cycle it was great. Give it a day or 2. It should get better

[Nexus 5 General] stamos*bp:
for those who have done a factory reset, what does that entail? i'm running a custom rom (cataclysm) but my battery life on 4.4.2 has been crap. are you just wiping data/cache/dalvik? or system/data/cache/dalvik? or going back to 4.4 and then flashing it manually to 4.4.2?

thanks!

That's right. Try an other kernel

[Nexus 5 General] californiarailroader:
I'm running Chaos Kernel and ART, and the battery drain on 4.4.2 is still HORRIBLE! I take it off the charger and it almost immediately drops to 99 percent, and after doing nothing but opening the app tray a few times it goes down to 98 after only a couple of minutes. It does great in standby, but the second you start to use it the battery drain goes up to absurd levels, I may end up doing a factory reset after all.
[Nexus 5 General] whitedragonz83:
Say you can obtain 4 hours of screen on time.

4 hours * 60 minutes/hr = 240 minutes

100% battery / 240 minutes = 0.42%/minute battery usage

5 minutes * 0.42% = 2.08% in 5 minutes

Say 6 hours of screen on time

6 hours * 60 minutes/hr = 360 minutes

100% battery / 360 minutes = 0.28%/minute battery usage

5 minutes * 0.28% = 1.40% in 5 minutes

If you are doing graphic intense stuff, imagine 2-3 hours screen on time. I'll leave those calculations for you. Factory Reset to your hearts content, but this is the drain with screen on based on straight math.
[Nexus 5 General] californiarailroader:
Well, It's just plain bad, I mean I can be doing nothing but having the screen on, no programs up at all, and watch the battery drain at outrageous levels. I am doing everything I can think of, short of turning the smartphone into a featureless phone. I've had smartphones since they first came out, and something just doesn't feel right with this battery drain, maybe LG and Google should have gone with a bigger battery, and if that's the problem then there's not much we can do. I will give it a few days, maybe it'll work itself out.
[Nexus 5 General] phatpaw:
So I've narrowed my horrible battery performance to attaching my phone to WiFi at my office.

I moved up to 4.4.2 early to midweek last week and was attaching to WiFi while at my desk. My battery was horrible as it drained twice as fast, and Android OS was the big violator. Not only was it using the most percentage, but it (in Use Details) showed a "Keep awake" value of an hour or so.

This weekend I was attached to WiFi while at home on our home network. My battery life was great. I had a 14 hour total on time on Sunday with a 4 hour screen on time. Android OS was far down the list of resources drawing battery. The "Keep awake" line never appeared over the weekend as well.

Today I returned to work, and automatically paired back up with the company WiFi. Sure enough Android OS started ramping up, and "Keep awake" was showing up and ticking.

I'm uncertain what about my company WiFi is troubling my N5. I've now realized that the random reboots I've had are always when connected to this WiFi, including this morning. Connection to Google servers seems to be firewalled, however this never adversely affected my N4. Essentially now I'm going to have to not connect to WiFi at work, and that is disappointing.
[Nexus 5 General] livito:
I also noticed that the battery was draining a little faster after the 4.4.2 update, so I turned off the phone and left it charging while off, after 100 % charged, I powered it up, disconnected it and that seemed to fix the battery drain, I am getting 48 Hrs of charge with out a problem.
[Nexus 5 General] californiarailroader:
Thanks! I'm trying that now.
[Nexus 5 General] polaris68:
Since I upgraded to 4.4.2 a few days ago, my SOT had dropped from a typical 4 - 5 hours down to about 2 hours on a charge cycle. A factory reset seems to have restored the battery life.
