In my experience it's random. Since 4.4.2 I've had battery issues with Android OS being the culprit. I almost never reboot my phone and finally decided to try it. Since rebooting Android OS has barely used any battery and my battery life, especially idle, is significantly better.

I'm now waiting for it to happen again. I know it will, just depends on when. Makes me doubt a factory reset will work. I imagine it'll work for a bit, but eventually it'll come back.

Devices:

LG Nexus 5 (16GB) White

Carrier: AT&T

ROM: 4.4.2 Cataclysm Dec-12 Release Date

Settings:

Nova Launcher Prime

Location Service: Off

Google Now: Off

Auto-Sync: On

The first boot up using new ROM with a clean system wipe gave me poor battery life. A reboot helped a bunch after your first boot on the new ROM. So far so good, the battery life is fairly the same for me from 4.4 to 4.4.2. I do have a ton of apps and games install as well. I am not sure if it even affects my battery life experiences but I've just notice a lot of talk about rogue apps. No known issues here. The picture shows medium to heavy use with good amount of gameplay. I typically last 2 full days with light to medium use.
[Nexus 5 General] sazabi neon:
do agree seems to be random and reboot most of time can stop the drain.

personal experience

sometimes........ideal only drain 1-2% for few hours;

sometimes........ideal can drain 10-20% in an hours;

do believe the radio is sometimes keeps working and drain the battery while sometimes can be ideal which don't drain the battery.

unroot 4.4.2 user
[Nexus 5 General] Valynor:
I can confirm what several previous speakers said: with 4.4.2 there is definitely something wrong with the idle drain.

-I usually lose 2-3% over 8 hours (WLAN/radio/sync on, Google Now off, good reception)

-since 4.4.2 this goes up to anywhere between 4% and 10% for the same time span, seems to become more over time, too

-a reboot immediately fixes the drain .. until it starts coming back slowly

-device is in deep sleep 98%+ of the time even when it loses 10% over night, no unusual kernel wakelocks either, also nothing unusual in the Android battery statistics
[Nexus 5 General] californiarailroader:
I have noticed the exact same things! Standby is awesome, they obviously need to work on the actual screen on time though ;) :D
[Nexus 5 General] whitedragonz83:
First night after a Factory Reset and leaving Dalvik mode. No Android OS bug over WiFi. Hopeful night two goes well.
[Nexus 5 General] thfreedumb:
id also be interested in this. Although by the first part of your statement it seems like it was fixed without messing with userdata. maybe if we could have more people with battery issues trying this instead of a factory reset?
[Nexus 5 General] dicecuber:
Been running factory resetted and using 10% brightness over the past 2 days. No change. Battery life is bad

Team Nexus 5 sucks
[Nexus 5 General] mokee92:
Is this normal guys?

I don't think it is...:confused:. I am running 4.4.2. Stock ROM and TWRP recovery.

please see attached pic.

What can I do to make the battery life a little better.
[Nexus 5 General] abbz123:
You have a lemon, RMA it.
[Nexus 5 General] Meltdown07:
Exact same here.

I did a factory reset and it was better for a few days, but it eventually fell back into this pattern again. I dont really want to disable Google Now. I like Google Now!
[Nexus 5 General] wngmv:
I am 90% sure it's 4.4.2

I was out without wifi the week 4.2.1 and 4.2.2 came out. After I came home, I installed the update, and without installing any new apps there dip in battery life is HUGE. I used to be able to get toi 50% after a day's use. Now 2 hours after I got up in the moring it's sitting at 30%.

I'm rooting my phone and going back to 4.4. I don't care how the camera sucks, this is not usable at all.
[Nexus 5 General] speedyink:
After waiting a few days because of this thread, I finally flashed 4.4.2 Catacalysm a few days ago. No issues here, seems pretty much the same as before. 26 hours into this charge with 63% remaining (50 mins screen on).
[Nexus 5 General] raffstyle:
Question:

Im on tmobile $30/month prepaid. I have a very bad network reception inside my house and my question is does having a weak reception of network really affect the battery? it says on my cell stanby that i have 75% "time without a signal.".

Im planning on trying straight talk with LTE for $15 more maybe ill get a better coverage since at&t is good in my area.
[Nexus 5 General] dazz87:
Yes weak reception will eat into your battery cause it will always try and find a signal. My battery life at home vs work is different. I get about two more hours of SOT at home vs at work
[Nexus 5 General] whitedragonz83:
2 nights now after a Factory Reset, removing Facebook and their Messenger app (using Chome to access), she staying in Dalvik my idle battery has finally gone to normal.

With full Goggle Now. Full location services (almost turned GPS off briefly and Wi-Fi background searching when Wi-Fi is off briefly).

Chromecast for an hour, Google+, Facebook, Play Newsstand, Gmail. Idle on Wi-Fi was around 0.5%/hr or less and about the same with string LTE at work. Bluetooth always on.

Hope this lasts.
[Nexus 5 General] matt_not_andrew:
I'm running stock 4.4.2 in ART mode with many of the power settings turned off and I'm getting moderate to low battery life. This mornings use has been extensively using lots if screentime below in purpose with 50% 3g time and screen set to 5% brightness.

When I got my phone on Tuesday I immediately updated to 4.4.2 before I installed any apps. Would a factory reset help clear any potential problems and help improve the battery life?
[Nexus 5 General] trsix:
try

I didnt read every post xda keeps reloading pages. But have you users with the problem tried going back to 4.4.1? We have 3 of these and all 3 get decent battery life on 4.4.2.
[Nexus 5 General] tmeader:
At the rate you're going given what you've shown, you're on track for 4-4.5 hours of screen on time. That seems normal to me.
[Nexus 5 General] matt_not_andrew:
I find that if I use the phone constantly I get good screen time. If my signal drops like when I'm driving out in the sticks or at home where I get no sign, then the battery life drops like a stone.

Today was the first time I switched from Location Battery Saving to GPS only. I wonder if that helped? I have Google Now turned hotword off, Location tracking off and the screen down low.

I should have quoted tmeaders comment. Sorry.
[Nexus 5 General] Greg Tolan:
I think a daily shutdown, leaving the phone off for a bit, and recharging until full really helps. It was mentioned as a "fix" a few pages back. It worked for me for a few days then back to ****ty battery with android OS, Google Play Services and cell standby being really high. I have now used this method 3 times and I am getting consistently good results. IE Back to great battery life with the normal stratification of apps/services showing up in the battery app monitor. There is some issue with 4.4.2 that eats the battery after a while. I don't think it is a memory issue as the phone doesn't slow down. Maybe it is a server side issue? Hopefully Google addresses this for 4.4.3, but for now I will continue to do this.
[Nexus 5 General] Russ T. Nail:
I've had horrible battery life with 4.4.2 as well. I have somewhat fixed the issue by adjusting what my Google account syncs. By far the biggest change though was turning off Google now. I never really used it but have had it on since I got the nexus 5. Something must have changed with 4.4.2 in google now because after turning it off I would say my battery drain improves by a good amount. The day before I did this I would go from 7:30am to now and be at 30%. same thing today but I'm at 63%. I feel like I was getting better results before but its still significant. Will probably try factory reset as well.
[Nexus 5 General] BoneXDA:
Such a pity that others included a fitting battery for the demanding HW while Google stayed "old school" with the capacity. Others are far more efficient per mAh too.
[Nexus 5 General] Hero_Guy:
Something that I've noticed is that when I'm connected to wifi, any wifi, my phone tends to wake up more-so compared to when I'm on 3G/4G. When I'm on mobile data, my phone never wakes up and I actually get far better battery life on a very weak LTE signal compared to a full strength wifi signal. Also Android OS would tear my battery up if I don't wake my phone up before unplugging it. I have no idea why but it works. Funny because I never had that issue on 4.4.
[Nexus 5 General] mdandashly:
My battery life has halved with 4.4.2.

I'm running stock and ART. Tried a factory data reset and still having the same problem.

My SOT is also not being reported correctly on the stock battery page. I'm seeing overnight unplugged battery drain of about 20%.
[Nexus 5 General] whitedragonz83:
ART? Dalvik?
[Nexus 5 General] mdandashly:
See edited post above. I have about 20% drain overnight in standby and it doesn't seem like anything is keeping the phone awake.

ART

My SOT is also not being reported correctly on the stock battery page.
[Nexus 5 General] JamieFL:
I don't see what the big deal is either. Good illustration with the %%%. As long as you get a full day's use out of the phone with normal use, who cares if you loose 1% of your battery in the first 3 minutes.

It could be that the phone stops Charging as soon as it nears 100% to prevent overcharging and damage to the battery. It could also be that Google is now being more honest with battery stats.

If you want to save juice, install Lux and adjust your screen brightness down. Install Tasker and turn things (data, Wifi, gps, etc) off when the screen turns off. And... keep a charger in your car just in case.

---------- Post added at 09:54 PM ---------- Previous post was at 09:44 PM ----------

if it's bothering you that bad, RMA the phone. I've had 3. All have had great battery power. I think these phones suffer from poor build quality.
[Nexus 5 General] JamieFL:
This is typical for me.
[Nexus 5 General] JamieFL:
Sorry for multiple posts. Couldn't get the screen shots on one post.
[Nexus 5 General] whitedragonz83:
I have no evidence, but after my factory reset I stayed with Dalvik. No problems are occurring. Uptime hit 60 hours and Dalvik feels great. Just needed time to cache apps. Until Google makes ART default I'll avoid it as to help eliminate it as a bug.
[Nexus 5 General] californiarailroader:
Well, it would bother anybody I think ;) As far as doing the return, I don't want to go through that mess for something that can probably be fixed with a software update.
[Nexus 5 General] Krzysiek_CK:
Last night I turned my phone off, charged it to 100%, and turned it on. After 8.5 hours at idle, overnight, the phone was at 90% and Android OS was on top of the list. Normally it would only loose 1-2%.
[Nexus 5 General] mdandashly:
I called Google and the CS rep told me she had at least one call similar to mine complaining about battery on 4.4.2. They did an RMA for me.
[Nexus 5 General] bblzd:
So after specifically stating that the software update is what made you're battery worse, they decided to replace the hardware?
[Nexus 5 General] mdandashly:
She didn't state that the software made the battery worse, just that she had gotten at least one call that day complaining of the exact same issue. Again, my battery was literally halved. I did another FDR and left it on Dalvik, I'll report back if thats any better, but so far, it doesn't look like it.
[Nexus 5 General] phatpaw:
That is a head scratcher. How is an RMA going to fix the OS?
[Nexus 5 General] mdandashly:
Couldn't tell you. Maybe a hardware problem exacerbated by the software/some incompatibility?
[Nexus 5 General] moldovanos:
I have 4.2.2 Purity rom with Franko Kernel and 4.4.1 radio. I loose only 1-2% overnight and I have 3.5 hours of screen time and thats without wifi. However when I flash CM based roms, my battery life is bad, Google services drain a lot, even though I flash the same gapps and use the same settings
[Nexus 5 General] TheIgster:
I was originally having some bad battery life with 4.4.2, but it would seem that the last week, it has gotten much better. Reboot of the phone? Things settling in? Dunno, but yesterday for example, I used my phone a bit, not a whole lot. About an hour and a half of screen time, reading various things, emailing syncing (both outlook and gmail), Google Now on as well as location and the phone was on for more than 18 hours and I still had 79% left when I went to bed. Who can complain about that?
[Nexus 5 General] :
I cannot confirm the battery being bad.

I have my Nexus 5 since about a week now and I really like the battery life. I used a Samsung Galaxy Note N7000 before and I compared both devices running the same apps with BetterBatteryStats:

Normal use (3G connectivity, several phone calls, reading e-mails, music listening with Spotify, Whatsapp Messaging, ...):

Samsung Galaxy Note: 4.5 - 8 % battery drain per hour

Nexus 5: 2.5 - 4.5 % battery drain per hour

Weekend use (WLAN connected, not much display time):

Samsung Galaxy Note: 1.9 % battery drain per hour

Nexus 5: 0.7 % battery drain per hour

In my opinion the Nexus 5 has a very good power management compared to the Note since the display is just a little bit smaller (5.0" vs. 5.3") but has a much higher resolution (1920x1080 vs. 1280x800). The CPU is much faster (2.23 GHz Quadcore vs. 1.4 GHz Dualcore). The battery is smaller (2300 mAh vs. 2.500 mAh).

This is why I am quite happy. Maybe the often mentioned battery drain is related to GNow and/or LTE? I don't use these two because I don't have an LTE-capable contract and GNow is not that good outside the U.S.
[Nexus 5 General] whitedragonz83:
Thanks for the comparison. GNow/Locaiton services use a lot for people moving often (commuting), and almost nothing when you are stationary. I think people don't realize this when they complain about GNow and Location services.

LTE is amazing on this phone btw. I almost believe I get less drain on LTE than on Wi-Fi. As you mentioned, the power management of the hardware (and software) is outstanding and welcomed since we only have a 2300mAh battery.
[Nexus 5 General] :
Well that's for sure that the battery will drain faster when traveling.

In my above mentioned "normal use" a daily travel to my office (about 45 miles / 70 km one way) by train is included also...
[Nexus 5 General] bblzd:
Compounding that effect is when people use GPS navigation which can drain the battery more then anything.
[Nexus 5 General] thedarktower:
100% wakelock.. ouch?!

I have been experiencing a complete, 100% wakelock over the last few days. I have no idea why these apps are running in the background; gmail I use, g+ I don't! According to the Total Newb's Guide to Wakelocks, the kernel wakelock is a placeholder...

i'm on stock 4.2.2, with xposed + gravitybox installed + ElementalX 0.18 kernel. Location off, sync on, wifi (good strength, I guess) on. Recorded loss was over night. Maybe I should try a different kernel (I don't think I had this problem while I was on franco or bricked... can't say for sure thought). Does anyone have any advice?
[Nexus 5 General] TurkzZ:
Lost 20% battery over night? Is there a way to monitor what uses battery ... or to be precise, which apps. On Stock non Rooted

Also with the GPS on high accuracy the battery gets killed when moving around, had to move it to battery saving and turned GPS off on the camera
[Nexus 5 General] californiarailroader:
Well, I did a factory reset a few days ago and that seems to have helped a lot, so far so good. I am also running Chaos 8.0 Kernel and ART in Developer Options.

---------- Post added at 05:07 PM ---------- Previous post was at 05:04 PM ----------

I hope to find out up here eventually, AT&T's LTE currently ends 50 miles south of me in Healdsburg in Sonoma County, thankfully, AT&T is all HSPA+ up here in Mendocino County. We do have LTE here though, from Verizon, U.S. Cellular and Metro PCS, poor T-Mobile is still EDGE. I am going down to Santa Rosa January 2nd on our montly Costco n stuff run, it'll be fun to see how LTE performs down there on the Nexus 5, it did pretty well on my Optimus G Pro.
[Nexus 5 General] mdandashly:
I got my new phone from Google after RMA. I'm running stock ART. Problem seems to be fixed.
[Nexus 5 General] nizbot:
You gave your self your advice. Go back to franco... Or stock. Troubleshoot man. You obviously know how to flash a kernel. Uninstall everything and install one app at a time. Also... Greenify.

[Nexus 5 General] TheArc:
Battery is fine for those who aren't heavy users, but still. Quite dissatisfied about the battery, Google once again has failed to put out a genuine phone. Packing a phone with powerful processors and GPUs will obviously need a good amount of power. And throwing in a crap battery? Then no micro SD, then horrible speaker sounds. Hissing noise in video recording, button rattling, camera off focus. I can go on with the list.

But I'm not happy nor angry about the battery life.
[Nexus 5 General] californiarailroader:
The only thing I'm not happy about on the Nexus 5 is the poor battery life, everything else is great for me.
[Nexus 5 General] lauk75:
I've had my N5 for about two months and Android OS consistently records the biggest drain on my battery, and the phone stays awake almost all the time.

Things I have tried that haven't worked: factory reset, Google play services update to 4.1, switching run time between ART and Dalvik, G+ backup only when charging, turning off Google Now hot word detection, waking phone up before unplugging, turning off wifi always scan, setting location battery saving / GPS-only modes, greenifying some suspicious apps (unrooted though), turning off location reporting and history, rebooting between two flight mode toggles.

These are mostly suggestions that I've seen either here or on G+. Hopefully it saves someone else the effort of trying them.

Any other recommendations as to what I might try? At this point I'm considering sending the phone back, but I'm not even sure I can now.
[Nexus 5 General] cgonzalez82:
What battery stats are you returning?
[Nexus 5 General] lauk75:
I generally get about 12 to 14 hours between charges with a screen time of between 2 and 3 hours. I know this isn't the worst battery life in the world but I also know it could be a lot better if the phone wouldn't stay awake so much. I've seen other people's awake time that's much better.
[Nexus 5 General] MardukAU:
Turn off GPS, Bluetooth and WiFi when u not using them. Install the DU Battery App and use it. I recharge my N5 every 2 days. Don't know why ppl complain about battery. Its great for me.
[Nexus 5 General] cgonzalez82:
How new is the device? You should be getting more than 2/3 hours screen on time. Do you have wifi on or data? Poor signal could be to blame, but more likely settings. I've got location off, Google+ off, brightness set manually, I've also turned my email account to sync never as that was causing a lot of battery drain behind the scenes.
[Nexus 5 General] lauk75:
I've had the phone for over two months. Signal is poor in most parts of my home but the drain happens even at work where signal is good. By the way I have also tried using AutomateIt to turn mobile data off when home and wifi off when away from home, but this hasn't had any effect. I do use G+ and Google Now. I can confirm that the drain does stop with location off, but if I have to turn location off completely then the phone becomes much less useful to me - I don't want to do that.
[Nexus 5 General] r0cafella:
I've been plagued by this very issue as many of you have without seemingly any reason.

Earlier today I flashed an older radio which has seemingly resolved the problem.

It's too early to say weather this is a real fix or just some freak occurrence but I'll try to keep this thread updated.

I would advise anyone to make sure their battery life issues aren't down to wakelocks issues before proceeding with flashing radios however.
[Nexus 5 General] polaris68:
I also live in a weak signal area and have a similar problem with battery drain. Up to 20% can be drained on mobile standby. What radio did you flash? I might give it a try.
[Nexus 5 General] Matrix_19:
stock - rooted.

I have a very good standby battery performance

however, when I'm NOT connected on WIFI ( hpsa+ ) ... sometime*, something happens and then I start having a standby battery drain, (I think it's Android OS), if I reboot, it doesn't solve this issue. What I have to do is to connect to a wifi network for one second and then disconnect it, back on mobile network and no more standby battery drain.

*It happened to me twice in the last week.

anyone having this issue ?
[Nexus 5 General] maddogdogdog:
I'm having similar symptoms to my work wifi too, therefore I have set my "Keep wifi on during sleep" setting to "only when plugged in" then there seem to have solved the battery drain issue. you might wanna give it a try.

New Nexus 5 Owners

Hey guys I just activated my nexus 5 from google today. Currently using sprint and am switching from a galaxy s3 running cyanogenmod 10.2 stable. My phone came with 4.4 and I see a notification to update which I assume will make the jump to 4.4.2. After reading this I'm a bit skeptical to make the jump. I will play with the phone for a few days to see the battery life I get as well as signal. My gs3 was getting terrible service. I live in a basement and now I actually get lte down here and am getting all calls and texts. After a few days I will root the phone and create a backup through twrp before doing the system update so I can go back if I have issues. For those having issues with battery I suggest you try an app called carat which is free in the play store. Open it once a day and in about a week it will tell you what's causing battery drains and expected improvement once you force close. I just installed the app and it tells me that the "update device" foreground app when closed will improve my battery by 57minutes. Also try greenify as others have mentioned. I left my wifi on and the phone dropped from over 90% battery to 45% in about 7 hours with no use which I found odd. I have wifi optimization and keep widi during sleep on. Have any of you tried the cyanogen mod roms?? If so can you report your battery life, camera picture quality and signal as well compared to stock?? For those that have tried it, if you are using sprint do you still have the option to update prl and profile or is that for stock rom users only? And lastly I would greatly appreciate if someone could direct me to an app for voicemail. I notice this phone does not come with one and you can only access it through the dialer. Thanks for the feedback guys and sorry for the long post.
[Nexus 5 General] r0cafella:
It appears that flashing a new radio didn't resolve the problem.

It was draining at 1.2% per hour for the first few hours (idling) then all of a sudden without any chances it started draining 5.5% per hour (idling).

I've performed a factory reset and flashed custom roms & kernels but the issue still persist.

I might have to go back to 4.4 which complete defeats the purpose of having a nexus device.
[Nexus 5 General] eon01:
Strange

Strange, I was hoping flashing the old radio would solve the problem. Try using Carat before you flash 4.4 back. What settings did you have? gps, wifi, location, sync, etc.
[Nexus 5 General] r0cafella:
The settings weren't uber battery saving location/gnow was enabled but they aren't the source of the drain.

I had these settings on 4.4 and battery life was much better drain of around 1.2 - 2% per hour without changing any of this the drain is now 6% per hour during the same usage pattern.
