First full day and I'm at 59% at the end of the day (13 hours on battery) and that's with a couple of hours browsing plus an hours spotify. Seems fine to me - loads of spare power for me to do more with it should I wish to.
[Nexus 4 General] ragmanchu:
Google service always up there with one of the most battery consumed app.... Anyone else have this issue? Anyway to resolve this if this is a problem?
[Nexus 4 General] Robert_W:
Impressed

I'm impressed. Yesterday I used the phone as usual, a few shorts calls, lots of texts, used facebook messenger for about a half hour, browsed facebook and instagram. Used the gps for around 15 minutes. Casual web browsing and it lasted the whole day!
[Nexus 4 General] tvdang7:
what's the best battery stat app?
[Nexus 4 General] ntt1409:
i was so disappointed w/ my previous nexus4's battery. only 3h30 screen on time with all sync off, no games, no calls/texts, no mobile data, no location access, wifi on all the time. the only thing i used is GG chrome.

But my second n4 is way better: 3h30 screen on time with all sync (yahoo, facebook, gapps, dropbox, skype, evernote), location access, nfc on, 40m on calls, no texts, mobile data and wifi on, about 30m of games (subway surfers), and hours of chrome. my 2nd nexus4 is still on 1st charge circle. Hope it will improve in the next circles :good:

I recommend Gsam :) it works for me
[Nexus 4 General] sotorious:
Got a new update for my phone today to going to put it to use tomorrow to see how things are. It seems like my battery life is Hetti g better just turned off NFC and locations. But I refuse to turn off Google now.
[Nexus 4 General] cheeseypuffles:
This is with a few calls, texts, internet browsing, and some gaming, all on autobrightness. I put the phone on airplane mode while I was sleeping. The results were good enough for me, especially with the poor signal at my house. As a side note, I noticed the phone gets fairly warm at the top, near the camera
[Nexus 4 General] Maxermus:
This was what I got out of my first full charge. My phone sleeps really well on Wi-Fi.

Have to say I am satisfied with the battery but as always more would be better.
[Nexus 4 General] Chris_GTR1:
i got some decent results. anyone know why mediaserver was so high? same goes for android system. im new to android sorry.
[Nexus 4 General] roughavoc:
I'm getting pretty much the exact same as you, but my media server is around 40% I don't even have any movies or music on my device, just need for speed most wanted and a few pictures

Looked around and haven't really found a solution to this
[Nexus 4 General] Vanhoud:
I managed to break the 5 hour screen-on time mark today. Here is my setup

CM 10.1

*Matr1x* v2.0 Kernel

1.5/384 min/max CPU - interactive gov

Wifi-only

Auto brightness

These screenshots include over an hour of full screen youtube (im assuming its the media server). This was done completely on Wifi, so you could probable take off an 1-1.25 hours if i was only on HSPA.
[Nexus 4 General] Younggun123:
I got 33 hours total time. 2 hours screen. 6 email accounts push. Everything on except NFC. All on WiFi. I really can't complain about stand by.
[Nexus 4 General] chrondroid:
After 4.2.1 update I must say I'm pretty impressed with my batt life now. I'm not running Google now and I've generally turned off location setting though I turn then on when needed. Had the phone about a week now and it also seems to improve as it gets used more. I'm looking forward to trying a diff kernel and rom

I have to add I used the S3 for about 6 months whithout LTE. It was from wind mobile. Batt life was great really had no complains even with heavy use. The n4 seems to be touchy in terms of services runnjng and batt life.

Sent from my Nexus 4
[Nexus 4 General] tpboi:
Flash motley's kernel, undervolt with the voltage table I included. i have tested it with stability test app 2.5 - scaling stability test, never crash, never restart, very smooth. N4 is a beast when it comes to undervolting. motley might even allow lower than 800mV in his next version but i am already extremely pleased with the battery life, getting around 6hours on screen time! This should solve the problem for people with poor battery life.

[Nexus 4 General] richyb86:
Right I have mostly been in the same boat as a lot of people here and felt the battery life sucked compared to other phones. My s3 was pretty good really. I was constantly getting bad results checking batt here and there wondering why. Travelling to jobs everyday not in local area. Playing with chrome a bit, browsing xda app. Bit of beach buggy game here and there. The odd app download. 40 mins of phone call. Office suite pro for work to. I realised standby is OK. But when in CONSTANT use it would heat up and drain quite bad. Sort of along the lines of off charge half 6 in morning then by 1pm down to 20% with about an hour and half screen on time. Bit worrying but that is with hspa on, Bluetooth on for car, WiFi on, GPS on, location services off. All Google sync on apart from photo uploads....But I found on a day where I didn't have to use my phone too much like yesterday all I would do is listen to music in gym = 1 hour. Any browsing like Facebook, twitter, instagram, xda, chrome mostly done on WiFi. Camera used quite a bit due to being at a party and viewing gallery. WiFi, GPS, Bluetooth data auto brightness all on. Google now, location services and WiFi location off. Battery life to the death was 16 hours uptime 4 hours screen on time. That's what I reckon is really use.
[Nexus 4 General] vollmilch:
This is what i get after a few days. Everything enabled (location services, WiFi, Google now etc). Half of the time I was in a non-wifi area.

I realized that battery drains a lot quicker when location services along with wifi are enabled when not connected over WiFi.
[Nexus 4 General] BennyJr:
^^^^you are on WiFi the whole time...
[Nexus 4 General] stuart0001:
Not necessarily as that shows also if WiFi is on but not connected.
[Nexus 4 General] shawnaye:
How are you guys finding the signal strength of the n4? Any times where you can't even get a data connection to eg Google.com?
[Nexus 4 General] chrisnk204:
Im not even rooted yet ... i can only imagine of i were ...
[Nexus 4 General] PoisonWolf:
I call BS on that screenshot unless if you can show that you did not charge it halfway.
[Nexus 4 General] alpha beta gaga:
I second that BS!
[Nexus 4 General] Reynt:
Nice fake. Too sad it isn't true.
[Nexus 4 General] hohoXD1233:
Hmmm, what is that smell? Ah yes, it smells like fine old BS! :p

Battery life is noticeably improving for me bit by bit, slightly over 4 hrs screen on time now with heavy usage
[Nexus 4 General] alpha beta gaga:
mirrors what i am finding. battery has improved with age (albeit just over 2wks old) but i'm more than happy with the juice i get
[Nexus 4 General] RealiZms:
Wow this thread simply proves that there's a million different ways to drain your battery on a Nexus 4......It appears people that turn off what they don't need or use get great battery life. Those that choose to have everything under the sun running get poor battery life. Go figure. Plenty of people are getting great battery life on their Nexus.

"Well I got auto sync on, data, wifi on all the time....just can't figure it out"
[Nexus 4 General] hohoXD1233:
Tbh, I turn everything I want on, and even though the battery life is very poor compared to my old iphone 4, I can now get a full days use out of it when previously I could barely get half a days use. So I'm not really complaining and it keeps getting better day by day so who knows how it'll be like in a month or two.
[Nexus 4 General] germanj:
That would only be benfitial in an AMOLED display. A static wallpaper, however, is better in this case than a live one.
[Nexus 4 General] Younggun123:
This is my first full cycle on 4.2.1. I have no idea if the latest firmware provides any battery enhancements. If this was consistent, the extrapolation would be quite good.
[Nexus 4 General] Younggun123:
Hmm my last post seems to have discarded the text when I attached the images. Anyway, this is my first cycle since the firmware change to 4.2.1. Not sure if that firmware rev. Had any battery enhancements but it it extrapolates evenly it would be a fairly nice run.
[Nexus 4 General] stefandunn:
My battery lasts for a day with moderate to heavy use, which is the same as my old Desire HD did on a custom ROM.

This includes browsing a lot on the internet with WiFi, watching youtube / google movie videos, use camera and recording HD, using Google now..
[Nexus 4 General] Serious_Beans:
Yeah I don't really want to be turning off and on things all day when I need them, it should just last all day, it has a beefy 2100mah battery and a A15 28nm core. It really has no good reason for why the battery is as bad as it is. It could be better but I'm sure some kernel devs or Google will get stuff sorted out and we will see some decent battery improvements.
[Nexus 4 General] nyijedi:
I used autostarts to disable a lot of apps from starting up on their own, and this has done wonders for my battery life. It's worked a lot better than freezing apps. I recommend giving it a shot.
[Nexus 4 General] rttnpig]:
3 charge.

Quite satisfied :D
[Nexus 4 General] tpboi:
Anyone experiencing varies charge time? Sometime it take like 3 hours to go from 5% to 50. Sometime it only take like an hour. what is causing this?
[Nexus 4 General] Bobbyballbags:
I would say that the battery has performed much better than I was expecting after reading the scare stories on this forum. I get more time out of a charge than I used to on my sgs2.
[Nexus 4 General] rmgill:
Stock, 2nd charge. Google sync, Google Now, and NFC on. Happy with the battery life thus far. Can't wait to try out some kernels soon.
[Nexus 4 General] monchy36:
how you keep the screen so low? mine is a 40%!!!!
[Nexus 4 General] PoisonWolf:
Simple. Since it is a percentage, it means that other processes are using more battery relative to the screen. If you want to reduce your screen percentage, make it run at higher CPU speeds and I assure you the percentage will drop. Lol.
[Nexus 4 General] jhock:
I love this phone and am not whining. It is worth figuring out how to make it preform well.

That said, I am getting much worse battery life than many and I can't figure out why. I'm not running any draining apps except Google now. GPS is usually off. Screen time is high because I am playing with it, but I'm not near 3-5 hrs that others claim and my brightness is at quarter.

Going to turn off Google now tomorrow and see what the difference is.
[Nexus 4 General] golfinggino:
Are you rooted and custom ROM / kernel or stock - your screen on time is very low - do you have NFC disabled ? Also if you don't use Google now then disable it, it drains a lot of battery
[Nexus 4 General] jhock:
Thanks for the tips. Yes, NFC is disabled and no I haven't rooted it yet. Full strength signal, though my mobile data is always on. Running stock, with very few apps installed (lightflow would be the only one that I am suspicious of in terms of battery drain). I will disable Google now to see if it makes a difference, but I wanted to use it.
[Nexus 4 General] Jayrod1980:
Well, coming from the galaxy nexus, this thing gets a little less battery than I'm used to with the extended 2000mah battery but not much less. The culprit is no doubt 4.2. Google needs to fix some bugs and get the polling situation sorted out. My n10 gets amazing battery life but it should with a massive batt and the most advanced arm chip ever put into a device. As efficient as the hardware in the n4 is, there is no excuse for Google not to make some changes to increase battery life. I updated my wife's galaxy nexus the other day to 4.2.1 and the jump from 4.1 sucks more battery too. I don't want to have to disable google's core features from jellybean just to up my battery life. Otherwise they should have stuck a 2800mah battery in their showcase phone. Again I don't think this is a flaw of the hardware lg made but rather the very rough condition of android 4.2.
[Nexus 4 General] kyo_vs_iori:
Google Now and NFC off, wifi on all day, Google Sync and Dropbox Sync on.

Tons of Chrome browsing, few minutes of Dead Trigger, Riptide GP, and Royal Revolt...also, max brightness (probably why my screen battery use is so high).

Battery life is great for me, compared to my HTC Amaze.
[Nexus 4 General] astalavista_thes:
Idle Drain

Do you know what's the "normal" drain in idle for the nexus 4? This night I have lost 14% in ~8h. Is that ok or there's something draining my battery?

I have everything turned on except my 3g as soon as I am on Wifi when at home.
[Nexus 4 General] phatpaw:
Quite happy with the battery. No real complaints. I'm running with GPS off, Google Now on, and NFC on
[Nexus 4 General] alpha beta gaga:
anyone else notice 'google services' showing in their battery stats since 4.2.1? sure i never saw it there before the update and i'm not using my phone ot apps any differently than i did before 4.2.1
[Nexus 4 General] raptir:
I got my Nexus 4 on Thursday and have been using it for a couple days. I'm going to try to take some real "data" over the next two days, but so far my battery life has been significantly worse than my Galaxy Nexus. With my Galaxy Nexus I was getting about 3-4 hours of screen on time with normal usage (HSPA+ web browsing, mostly) plus an hour of calls over bluetooth in an 18 hour period off the charger before killing the battery. I am now not even getting to two hours of web browsing with no calls. Idle battery life has been terrible as well. This morning on my hour ride in from work with WiFi/Bluetooth off and the phone sleeping in my pocket, I was down to 92% with the top two usages being Phone Idle and Cell Standby. my battery graph show no wake periods in that time except for the 10 minutes that I had the screen on.

I'm going to do a factory reset and see if it gets any better, but the only apps I have installed are two games (subway surfers and hill climb racer) that I've had no issues with in the past.
[Nexus 4 General] kgeissler:
I have the same problem. Google Service is using well over 50% of my battery and don't know why. I even did a factory reset yesterday and still have the same problem.

See my thread here:

[Nexus 4 General] ksc6000:
Worrysome, as my battery life on my galaxy nexus is VERY similar to yours. I wonder what i'll get when UPS finally decides to actually send me my damn phone.
[Nexus 4 General] drpepe:
pretty happy so far with my nexus 4 battery..

I usually listen to audiobooks for 1-2 hours a day, sporadic browsing, xda, fb, 2 email accounts syncing - basic stuff.

No GPS , switch between 90% 3g / 10% wifi, screen on auto, disabled google now and locations.

After a full day at work I will have about 40% left.
[Nexus 4 General] CMNein:
It seems to get downright stuck at times. Has been hard to find easy to understand info about Li-Po batteries outside of RC forums.
[Nexus 4 General] [hfm]:
Mine is just a little worse than my GSM GNex. I had the 2000mAh extended battery and used black themes and backgrounds and wifi everywhere I could but I left my multiple accounts pushing (gmail and touchdown) and location services and g+ always on weather widgets updating etc... I could top out around 6 hours of screen time. Usually got 4.5-5.5. I haven't tried to do a rundown test on the GNex yet from 100->0 but from the numbers I'm seeing it looks like I would be maxing out around 4.

One thing I will say though, I love being able to switch from the dark themes it's so much more pleasurable to use. Disregarding screen time of my old GNex with extended batt this phone is far and away better.
[Nexus 4 General] csloomis:
So I am not the heaviest screen on user. On my Verizon GNex I average about 24 hours with the extended battery. So I have been amazed with the battery life of the N4. I was able to get 23 hours the first day with the N4 after charging it to full. The longest that I have gotten has been 3 days 20 hours, this was with lighter than normal usage of the phone.

I would post pictures but I am new to the forum.
[Nexus 4 General] monchy36:
What I'm doing wrong here?
[Nexus 4 General] GJ123:
I think it's important to realize that the software on the Nexus 4 at this moment is far from optimized, I expect it to be way better in a couple of months. When all strange bugs are ironed out and the devs do something magic!
[Nexus 4 General] CMNein:
Full brightness, full time?
[Nexus 4 General] raptir:
I'd say my bigger concerns are the fact that a) my Galaxy Nexus running 4.2 gets significantly better battery life than my Nexus 4 running 4.2, despite having a smaller battery and a more power hungry screen (at least on the white backgrounds that are so common on the web) and b) there is so much variation in the battery life. Despite reporting similar usage people are seeing vastly different numbers for screen on time.
[Nexus 4 General] monchy36:
I wish was that...
[Nexus 4 General] nosenuggets45:
Battery life was pretty good the first couple days... but since 4.2.1, I've been having problems. There is definitely something wrong here...

Seems to be a pretty common problem. I'm going to try a factory reset, but I feel that an OTA update will be needed to fix this.
[Nexus 4 General] tadghhickey:
3g

i know people have been saying that on 3g the battery life is worse but i have noticed a significant difference i get much worse battery life on 3g i can just about make it through the day with low to moderate use.
[Nexus 4 General] TobiS87:
No Problems so far with battery life. Lasts me through the day easily.

Lot of xda, YouTube and browsing with chrome.

Got NFC and haptic feedback disabled. Just found out that disabling Wifi when not in use saves a lot of juice. Google Now is on btw.
[Nexus 4 General] jhock:
Just an update.

Disabling Google now didn't really make a difference. I am wondering if there is a battery issue (not software or settings). Those who get bad battery seem to have similar times for screen - around 2 hours.

Installed a new battery app with more detailed info (signal strength and battery temp).
[Nexus 4 General] Lockeskidney:
Going strong
[Nexus 4 General] gdap:
Been using WiFi most of the day and played a lot of fruit ninja.
[Nexus 4 General] ceroglu:
I have noticed something recently, may be It could explain the drastic battery drain for some people. After using Spotify my device doesn't go back to sleep. Even after doing a force stop the device stays awake. I think, Spotify triggers android media server to start working and then the media server never stops. I noticed even just listening one song results in android media server to take most of the juice from the battery. After restarting the phone, the phone goes back to normal and phone goes back to deep sleep. I have an offline playlist that is downloaded on my phone and strongly believe this could be battery drain issue for most the people. Without Spotify, my battery does great job, I can get through whole day of use with 4hrs of screen time, but as soon as I use Spotify it goes 3-4 times faster. I am not sure how to fix this, but this problem was not an issue on any other Android phone that I owned. I flashed factory image recently to see if it will get fixed but still the problem is persistent. I also tried different kernels with no solution yet. Looking forward to see some inputs on how to get this fixed.
[Nexus 4 General] yfbc:
This phone has some inconsistencies in battery usage, some days I get excellent battery life with amazing idle drain. Other days such as this morning I find that my battery will drain 20% over the course of an hour and then check battery stats to see 15 minutes of wake lock from Google plus and 10 mins of wake lock from Google talk, these apps have very little reason to spend so long waking my phone from deep sleep :-\ .
[Nexus 4 General] alpha beta gaga:
went to bed last night 11pm phone on, wifi left on, data on but no data sync that i know of, woke at 7.30am phone lost 2% so pretty happy with that overnight drain
[Nexus 4 General] twomix9900:
There's a bug in HD widgets that messes with your phone's ability to get into deep sleep. If you're experiencing bad battery life and you are using HD widgets, remove it until they patch it.
[Nexus 4 General] stuart0001:
I've replaced my phone and am getting about 30-40% better battery life now. Other issues on the old phone but not the new one were random reboots, getting very warm when supposedly idle & erratic battery percentage readings.

If you have these symptoms then I suggest your phone is faulty and might be worth a swap.
[Nexus 4 General] TeamAlpha:
Actually seems to have improved for me now. This was a whole day of University from 7am to 2am.
[Nexus 4 General] ml2514:
When you guys post make sure to add the screen-on and connectivity (how good your reception is) as well. The screen that shows how long the phone has been going really doesn't show us much.
[Nexus 4 General] Shodney:
Google Plus has always been a massive wake lock for me, some days it can have 2 / 3 hours wake lock over the course of 8 hours. As you say, there's absolutely no reason it should be awake for that long. I have instant upload set to only upload on wi-fi and when charging, so that can't be it.

This was the case even on my Gnex, so I think it's the app rather than the phone.
[Nexus 4 General] ptrm2:
Yesterday I used about 70% of the battery so it should last fine for me but I didn't charge last night. I am wondering if it is ok to charge at 30%? What do you guys do?
[Nexus 4 General] yfbc:
Basically what I've noticed is the battery life on this phone can be truly amazing, but everyday there seems to be some rogue process killing the potential.

There needs to be a way of having stricter manual controls over what can sync and when these processes can sync. Such as the gallery app taking 23 minutes of wake time syncing 3 images....

Perhaps to only allow syncing at certain times? The auto sync menu needs to allow for the ability to turn on/off specific processes syncing and/or perhaps schedule them.

If you don't mind rooting and flashing a new kernel its beautiful I haven't had any "rogue apps" drain my battery I'm consistently getting 3-4 screen on with about 10-13 hours off charger and I'm a heavy user always gaming always on xda and have pretty much all syncs on except location
[Nexus 4 General] chrisjcks:
I DEFINITELY don't get as much battery as my ONE X.

And I should get more.

28nm vs 40nm

2100mah vs 1800mah

And auto brightness on the Nexus 4 is set lower too.

So, there is most certainly a software issue with battery for this phone.
