What are you talking about? My battery life is better than your nexus s and our N4's have a quadcore with a much larger screen. I have no earthly idea why people are having bad battery life with this phone.

Are people wiping battery stats in cwm or twrp. Don't do it! Your phone will adjust itself accordingly. Also stop completely draining your battery unless you must. It does absolutely nothing to help.
[Nexus 4 General] Ulver:
I had pretty horrible battery life at first and bad idle drain too. After a few charge cycles its been so much better. I did turn off Google now, maps, location, etc. Now I've been constantly getting 4 hour screen on times which is plenty for me. Even if this phone had a removable battery, I would never have to use it.
[Nexus 4 General] barondebxl:
The exact same for me.
[Nexus 4 General] nyijedi:
Does anybody know why locked apps still show up as running in bbs? Things like Maps, Facebook, eBay,and Sportstap are still causing alarms in bbs, even when locked.
[Nexus 4 General] lurtis:
Why would you wanna turn off all the awesome features of the phone just to get decent life? This whole thread just makes me want a note 2 and keep maps, Google now, and location settings on....

I turn off Google now on my nexus s 4g right now as with it on the drain is retarded but hey its almost 2 years old I wasn't expecting it to be perfect with brand new software but a brand new nexus having to do the same thing? As the YouTube video states.... "UNFORGIVABLE"
[Nexus 4 General] Ulver:
They are cool features, but I honestly don't use them.
[Nexus 4 General] darkcurrent:
you don't use google maps....
[Nexus 4 General] Soldier 2.0:
Hello guys! How does this phone's battery life compare to the galaxy nexus? I know a lot of you were gnex owners. Thanks! :good:
[Nexus 4 General] montrealguy:
Can anyone here offer a comparison of the battery life on the Galaxy Nexus compared to the Nexus 4? My Galaxy Nexus runs out of battery very fast on 4.2...I was thinking of getting the N4 but have been reading a lot of reviews that say the battery life is terrible.
[Nexus 4 General] Monk4Life:
I still have my GSM Galaxy Nexus so I can give you my input. My GN is also running 4.2 with the stock battery that came with it. My new Nexus 4 is honestly getting twice the battery life compared to my GN with the same exact settings. Screen on time has also doubled.

I still can not figure out why some people are claiming to be getting bad battery life. I don't think there is a bad batch of N4's but if people are installing custom roms and wiping battery stats and then not letting their phone settle for a few days then this explains their issue. Stock rooted 4.2 just like my GN is having flawless battery life.

I will say that when I first received the N4 the first few battery charges the phone was getting the same life as my GN but I swear that over the week I have had it after each charge the battery life is lasting longer and longer to where now it has doubled my GN.
[Nexus 4 General] :
Testing battery life/performance setting the cpu at only 386MHz. As I said the experience is really smooth (I would say similar to the Galaxy Nexus).

Here are some screenshots (after a while the system set the old frequencies back, that's why you see other frequencies).

Video decoding (over network!) :

1080p : sluggish

720p : perfect

YouTube HD videos : perfect.

Scrolling/zooming (chrome) : perfect
[Nexus 4 General] :
Battery life is really killing this phone for me, dunno what Google and LG were thinking. Barely lasts a day.. :(
[Nexus 4 General] Pully:
Gmail and Whatsapp on push sync and auto brightness set.
[Nexus 4 General] :
Can you show us the version you're running please?
[Nexus 4 General] jabbeboy:
It depends in what the hell you are doing. Of course the battery will drain if you have hAve the wifi on all time and so on. Maybe you sell this device and buy yourself a Motorola Razr HD Maxx, and stop complaining.:angel: just sayin.
[Nexus 4 General] B97:
Does anyone's battery get hot quick which causes lag?
[Nexus 4 General] :
This is a forum, its a place to talk and vent frustrations and no I dont have wifi on all the time. If you'd like me to be a mindless Android drone and say everything is perfect about this phone then thats not going to happen. :cowboy:
[Nexus 4 General] Carter07:
Hi, I don't trust too much these programs to lower cpu clock.

Snapdragon s4pro is the only cpu that uses Asynchronous Symmetric Multiprocessing that means the cores can run each at different frequencies, so you don't know if you are underclocking all 4 cores or only 1 core.

I think the authors of setcpu and similar apps should update their programs to support s4pro aSMP so we can control the frequency and governator of each core indipendently from others.
[Nexus 4 General] :
I agree, but have you seen my screenshots?
[Nexus 4 General] :
New screenshots...
[Nexus 4 General] Pully:
Here you go.
[Nexus 4 General] p5f:
After a day of using the phone the battery life seems better than the GNex but worse than the S3 (when running stock kernels and roms). The GNex had appalling battery life so being able to swap the battery was a god send. The S3 had amazing battery life on stock Kendall and rom and buying 2 spare batteries was a waste of money.
[Nexus 4 General] :
Thank you. Don't you have any network issues (your previous screenshots)?
[Nexus 4 General] Stadsport:
Well here are the results of my first battery run-down from a full charge. About 15 minutes of talk time and just over 5 hours of screen-on time. All web browsing, texting, BaconReader, and Scruff with the occasional YouTube and stuff.

(Screenshot taken at 4% remaining. It made it to 5:20).

For comparison, I got about 1h45m out of my LTE Galaxy Nexus in the exact same usage situations. I'm very pleased with the battery life so far.

Edit: As expected, it waited at 1% for quite a while before deciding the battery was actually dead, and ultimately made it to 5h30m of screen-on time before shutting off.
[Nexus 4 General] danielsf:
Yeah that's how I am finding the battery too, noticeably worse than my international s3 but very lightly better than my international s2 (which was a bit better than the galaxy nexus battery wise). Although something I trying to get used to is the screen difference between the s3 and n4. I mean I thought my n4 had a badly under saturated screen when I first saw it and I thought I had a broken device, with a lot of reviews saying the screen was really nice. But after using it a day and not looking at my old s3, the display looks good and it is sooo much more sharp than my s3, although there are some colors like the blue background on the google music app which the nexus 4 can't seem to display right (just look really dull, compared to my s2, nexus 7 and s3.) Over all colors look a little better than my nexus 7 but now I go back to my s3 and the screen is uncomfortable on my eyes now, especially reds and orange's. I am probably so biased to AMOLED screens due to ever smartphone I have every had having one, my htc desire, s2 and s3 all had AMOLED screens. How do you find the screen difference between the s3 and n4? I am wondering if the battery will get any better from software updates as I thought IPS+ was more efficient tech than amoled, also the screen is smaller. Lastly the SoC I thought was supposed to be more power efficient.

Edit: One last question, anyone else notice this phone gets substantially hotter than the s3, as it's starting to concern me?
[Nexus 4 General] Pully:
My phone service signal rarely gets above 2 bars of 3G at home but no major connectivity issues. Was the same on my Arc S and my partners ZTE Blade - just a crap area :)
[Nexus 4 General] MattSkeet:
dude 15hrs is more than enough. Do you constantly play on your phone?? My Galaxy nexus managed to last about 2-3 days if I was busy over the weekend and didnt play with it too much
[Nexus 4 General] Martin_Ro:
Ok, some observations I have made regarding battery with our N4:

1. 3G eats up very much when signal isn't that good. At home I have rarely more then 2 bars and I can see the battery drain much. Changing to 2G(if 3G is not currently needed, especially @home, where WiFi is available) and the drain is much much less

2. Deactivate background services like Currents,Talk,News and Weather, Google Now and so on. They seem to be the source of a big portion of "Android System" usage (after I have rooted my phone now, I completely uninstalled Currents,Talk and "News and Weather").

With the above settings I have had 1% of drain in 3h this night.

You are reading right, 1% only in 3h.

Off course not with normale usage, but only standby, but anyway, before I have had done the above thinks, the drain was around 2-5%

per hour

without using the phone, so it will help for sure.
[Nexus 4 General] theguitarman94:
2100mAH battery and an efficient S4 Pro this phone should easily be getting a good day and better battery than people are reporting. It's bound to be a software bug that hopefully will be fixed soon :)

---------- Post added at 12:32 PM ---------- Previous post was at 12:27 PM ----------

Thanks for the tips. Can you still get OTA updates when you're rooted on a nexus device? I've always owned HTC's so I don't know what they're like with nexus devices. Do the updates corrupt the phone if you've uninstalled system apps?
[Nexus 4 General] PhilipL:
Hi

Are people testing their phone until the phone turns off due to an exhausted battery? If you are just using the percentage remaining then this may not be accurate all the time, especially when the phone is new. While you can't calibrate a lithium battery, and the battery itself will give top performance from the first charge, the battery remaining reading may be under reporting and needs to see a few cycles off flat to fully charged to read more accurately.

Regards

Phil
[Nexus 4 General] Ulver:
Nope, not that much. But if I had to I would turn it on.
[Nexus 4 General] Capt.PP:
Anything that use to connect to Google's server such as Maps, Location tracking, ect.
[Nexus 4 General] Falzar:
I find it funny that some people want 4 hour of on screen time makes me wonder what are people doing with all there time.
[Nexus 4 General] Ulver:
I'm playing with my phone! :D
[Nexus 4 General] Falzar:
Never mind then ^_^
[Nexus 4 General] keijikage:
I commute an 1 hr 15 minutes to work, so I run Waze to try to avoid traffic.

First day out, left my house at 95% got to work with 60%, screen off the whole time (I ride a motorcycle so it is not really feasible to run a charger and there is no need to keep my screen on)

I normally lose 20% doing the same thing on my galaxy nexus. I'll give it another try tomorrow, but boy that was disappointing.
[Nexus 4 General] chiensibut:
does google now drain battery?
[Nexus 4 General] Younggun123:
Yep.
[Nexus 4 General] PoisonWolf:
A ton of battery.
[Nexus 4 General] sidamos77:
No, it's the Location Services. I have Google Now always active on my GNex, but all checkmarks in Google Maps -> settings -> location are unchecked. No battery drain for me.

Of course, this way Google Now is less useful. But it already learned where my home and my work place is (had Locations Services on initially for a while), so it's still working, like it displays the weather, the time to travel to work or home and cinema infos.
[Nexus 4 General] d1pham:
My wife's first day with the N4 =

~15 hours uptime, 50 minutes talk time and 3:32 screen on with 10% battery life remaining.

All HSPA, WIFI/GPS disabled, auto brightness on and no tweaking/disabling of apps.

When we first received the phone we let it charge powered off for 2-3 days straight. I assume the battery life is going to get better after a few more cycles.
[Nexus 4 General] Capt.PP:
Why would you let it charge for a couple of days? I understand the reasons of having it fully charge before using it. Having it charge for days actually does more harm to the battery.
[Nexus 4 General] d1pham:
It just happened we left it plugged in while waiting for the SIM to arrive. No real reasoning behind it. I'm sure the phone stops charging once the battery is full anyway.
[Nexus 4 General] Capt.PP:
FYI,

In your case days. "15 hours will potentially cook the battery into a thermal runaway and cause it to fail catastrophically. The charge rate of a typical consumer Li-ion battery is between 0.5 and 1C in Stage 1, and the charge time is about three hours. If you were to extend that to 15 hours, you would essentially have "trickle charged" the battery for upwards of 12 hours, and LI batteries can not stand trickle charging once their rated capacity has been reached.

As it is, these phones won't allow the battery to be charged beyond the point they reach 100% anyway (3 hours for the RAZR, 5.5 hours for the MAXX), so leaving it on charge for beyond the 100% mark is for the most part waste of energy. The charging system shuts down once the battery reaches 100%, and then stands by waiting for it to deplete to 90%, at which time it resumes charging to 100% and then shuts down and the whole process repeats itself."
[Nexus 4 General] vollmilch:
I was having heavy battery drain as well when my nexus was sleeping and no WiFi in reach. I fixed it now by unchecking "allow apps to use my cell data and WiFi to find my location" in the location options or however its called in English.

Background was WiFi which never slept when the screen was off.

Before that I lost about 10 % of battery within 2 hours. Maybe worth a try.
[Nexus 4 General] alpha beta gaga:
so basically you have completely switched off all location settings? no GPS? no 'WiFi and mobile location'? doesn't that defeat the purpose of having a smartphone? surely better to have at least one of those enabled.
[Nexus 4 General] sidamos77:
This is only true for some phones, I guess mainly older ones. Newer phones do not trickle charge the battery. They shut off power to the battery when it is full and then draw power directly from the charger. So, no harm done to the battery.
[Nexus 4 General] vollmilch:
no i only disabled "wifi and mobile location"
[Nexus 4 General] alpha beta gaga:
huh! you don't find gps more draining?
[Nexus 4 General] fnf:
I concur, with syncing and location service turned off, brightness at auto (granted I usually keep my room dark so effective brightness is between 5-20%), it is quite easy to get 7 hours with web browsing. This is with everything stock, albeit rooted.

For streaming 1080p content via Wifi, I can get up to 5 hours (extrapolated from the 60% battery drain after a 3-hour long movie).

I get what some of you are saying about turning useful features off, but I am a minimalist and treat my Linux laptop the same way (only installed what is necessary) so I don't really miss anything from the phone.

Will gladly post screenshots as I got a chance :) . The point is, though, that it is possible to get that much battery life out of the thing when you desparately need it.

It is also rather funny that as soon as I got my Nexus 4 and passed the Galaxy Nexus to my wife, the phone started to eat battery for breakfast. It's been having gps-lock non-stop.
[Nexus 4 General] hallucynogenyc:
Something is definetely ****ed up here:

I fell asleep while chatting with the phone on the wall charger, I woke up to this.
[Nexus 4 General] vollmilch:
of course gps its a bigger battery hog. the problem with mobile location is that obviously wifi is scanning all the time when not connected.
[Nexus 4 General] calanizzle:
What's the point on having all mobile/wifi off? brightness 0% etc etc, If I want a device for games/browsing only I would get an ipod touch, ps vita, etc.

Results of screen on time that does not have mobile data on, sync, even location, are not accurate. Why would we buying high-gamma phones then? if we're going to disable everything in order to get more juice?

I currently get 4hs on my s2 (settings on signature) and I'm pretty sure I'll get more with nexus (arriving in 2 weeks), I have 3G on all day, wifi sometimes, gps on (cerberus), sync on all time on gmail (I need it because of work).
[Nexus 4 General] dwang:
To those of you getting bad battery life. Do you have HD widgets installed?

There seems to be a bug in HD widgets that is preventing the phone from going into deep sleep as often as it should.

Try uninstalling it and see if that helps with battery life.
[Nexus 4 General] calanizzle:
Your mobile network was not good, therefore, your phone kept trying to get good signal = battery drain
[Nexus 4 General] fnf:
I actually find it more useful to have battery life reports confined to a single item under test (so general usage, Web browsing, video streaming, navigation, etc. should all have different settings as opposed to have everything turned on).

Battery life is most important to me when I'm on the go. Knowing precisely how much I can use the phone for each separate activity helps me conserve it when I need it most.
[Nexus 4 General] thegregulator:
The point is for some people battery life is more important than having their phone constantly tracking their location. I know where I am, I don't need my phone to tell me. If I need a traffic report I can turn GPS on. Just because some of us don't have everything running all the time doesn't make our battery life results less accurate.
[Nexus 4 General] calanizzle:
Yeah, you have a point too.

But, If I buy a high-end device, I want to have features all the time and not disabling them, etc etc. It just bothers me tho.

Batteries must improve.

---------- Post added at 10:31 AM ---------- Previous post was at 10:22 AM ----------

Don't focus on GPS only, that can be off tho. Personally, I have it on, because of Cerberus. But what about sync (for mails, not social feed), 3G/4G, even brightness, what if I'm a user that want a really bright screen, I can't have it, because my phone will die before mid day.

P.S.: I do tweak my phone to get more juice but I would feel more happy/satisfied If I just wouldn't need it.
[Nexus 4 General] jmejiaa:
I miss my toggles from touchwiz :(

So far the battery on the S3 was def. lasting longer...
[Nexus 4 General] chrondroid:
I noticed a minor improvement after disabling Google Now. I've noticed as well Android OS running 5m using 12% battery once in awhile. Whatsup with that? Why so much use for such little time? I dont have screen shots at the moment but I will update this post tonight after work.

Also did anyone notice any improvement after the 4.2.1 update?
[Nexus 4 General] cc999:
Battery life = SGS3

I can make this post with confidence since I had the SGS3 for the last 7 months.

I am a moderate user, exchanger server and Gmail syncing continuously.

numerous text msgs., internet browsing, Flipboard usage, Sirius XM stream.

Constant Bluetooth connected to car. I do not play games

The battery life on the Nexus 4 is as good or better than the SGS3 period.

I have a 2nd batch phone FYI. I am completely happy!

[Nexus 4 General] calanizzle:
This is a real life experience, thanks! :good:
[Nexus 4 General] UCFJake:
I'm not sure why my GNex has such bad battery. I can rarely make it past seven hours. The best I could get was when I was on a limited (1mbps) WiFi connection and didn't turn the screen on. I had the brightness on super low and not automatic and WiFi off most of the time. GPS off too. I did have Google Now running and this was all with stock battery. I regularly cleared out running apps because it was noticeably slowing down especially after the 4.2 update.

I have only had the Nexus 4 for two days and I am still investigating battery life hut so far with similar usage it is blowing my GNex away. For example around 1pm I usually needed to plug my GNex (below 20% left) in during a moderately heavy use day. Today I've been using my N4 in a similar fashion and I just dipped to 69% and it is almost 1pm. I am seeing amazingly better life on this phone.

I had the GSM Play Store GNex on T-Mobile in an HSPA+ coverage area. N4 on same network with new micro-SIM card.
[Nexus 4 General] Jayrod1980:
I've only had mine a short time, and on Mon/Tues this one will be RMA'd for the screen, but my impressions so far. Battery drains pretty fast and charges slowly. I noticed the first time I charged it didn't want to go above 97% charge. The held charge according to the numbers seems to be getting better, but it definitely drains faster than My 2000mah GSM Galaxy Nexus did. I'm expecting to get better life out of this phone after a few charges. I think there's something to that whole "new battery tech" that LG was talking about. Maybe it takes awhile to condition the battery to accept the higher charging capacity that they claim. Also, this is my first Lithium Polymer battery phone, so I'm not as experienced with its characteristics first hand like the Li-ion.
[Nexus 4 General] hohoXD1233:
Compared to yesterday, battery is much better now though still nowhere near as good as my iphone 4. Over 10 hours, 1hr 20 mins screen on time in and battery is at 58%. Tried lowering the brightness, switching to a standard wallpaper, disabling location services when not needed, etc. and now I don't really know how to improve it further. When I got the phone, I didn't think that I'd have to limit using all of its awesome features to preserve battery life.
[Nexus 4 General] rttnpig]:
Use of screen 1:30. First 6 hours airplane mode, was sleeping!! This is my second charge
[Nexus 4 General] monchy36:
Same here! I thought it was going to be better but it drain really fast!!!
[Nexus 4 General] hohoXD1233:
It's pretty stupid tbh, don't see how I can play a game whilst I'm not near a charger, I'm just hoping a future android update will fix the battery life. If I can work out what this "media server" is which keeps draining my battery and what apps use it then it should be fine though.
[Nexus 4 General] shawnaye:
Thanks for the review bro.

Really a big factor in whether I'm upgrading from my gnex or not. Cause I'm heavily relying on my spare battery on most days. But i barely get through half of my spare battery by the time I'm home.

Your review just makes me feel that I'll find a way to survive if I do get a n4. And with all the kernel and rom optimizations yet to come. I'm sure it'll be possible.
[Nexus 4 General] hohoXD1233:
Just read that the battery life for the N4 may get better the more charge cycles you go through, any impressions from people who have had it for around 2 weeks? How does it compare to the first day?
[Nexus 4 General] monchy36:
Mine is the screen that kill most of the battery... I just change the live wallpaper to see if improve...
[Nexus 4 General] calanizzle:
use a black wallpaper
[Nexus 4 General] ksc6000:
I have to think there's something wrong with android 4.2, including 4.2.1.

A ton of people on the galaxy nexus have been reporting very bad battery drain after getting on 4.2.

I am avoiding 4.2 by changing my build.prop on my Galaxy nexus to keep me on 4.1.2 and my battery life is excellent. On 3G all day I'll get 4-5 hours of screen time with the 2000 mah battery. My screen time is dominated by Google Talk. I love to chat.
[Nexus 4 General] raptir:
That's primarily for AMOLED screens. You might see a slight difference with an LCD, but it won' t be major.
[Nexus 4 General] Heartbreak:
Yesterday was the best battery life I've gotten so far. 4 hour screen on time with Google Now and NFC disabled, and programs not required by the OS disabled at bootup using System Tuner. Google Now doesn't really work all that well for me and NFC isn't quite ready in terms of availability in my area. Most of the day was spent on Wifi at my apartment and school and the rest was spent on HSPA+. I have Wifi turned off when I'm outside of campus or my apartment and when I am at either of those two locations I have data turned off.
[Nexus 4 General] nexusguy74:
Mine was bad the first week needed charging after 8 hours now two weeks later I can't believe how good it has got.
[Nexus 4 General] jarjar124:
I can't seem to find what is causing media server to drain most of my battery. :/ only first charge though. Still have hope
