Could just be your battery going through its charge cycles. It's bound to get better after 4-5 days. I have read disabling Google Now and location services saves battery but I wouldn't think by that much. Either way, you're getting about the same battery life as me, so I'm glad I'm not the only one who's satisfied!
[Nexus 4 General] razball:
Finally battery life is looking better but still not what some of you are getting
[Nexus 4 General] Serious_Beans:
I really thought I'd get 4 hours of screen on time with a new A15 soc and 2100mah battery I don't understand how I get the same battery as I used to get on my gnex. This is pretty frustrating because I used to get 3-5hrs on my S3 and this phone has a more efficient soc and newer os. One thing Google can't get right with their nexus phones is battery life....or maybe I just have a fault battery or phone.
[Nexus 4 General] shawnaye:
Hold out for kernel and rom optimizations. I'm sure you'll reach a minimum of 4 hours.

Also depends if you're on wifi or data.
[Nexus 4 General] funkyblue04:
No, Android is just **** at battery life.
[Nexus 4 General] Serious_Beans:
I don't understand why Google can't do what LG did even. The optimus g has better battery life than this phone and its the same hardware. I feel as if they used one of those crappy 2100mah knock off batteries that is only actually 1700mah. Android is a battery hog but other OEMS have found a way to do it. I hope custom Roms and kernels give me at least 4 hrs because I like to actually use my phone.

The part that is bugging me the most is that is has the same battery life as a phone with a smaller battery and less efficient soc....how the f*&k is that even possible?! Can the software really be that bad? do I have a faulty phone? I just want some answers :(.
[Nexus 4 General] AshtonTS:
Just give google a chance to get out a couple more 0.0.1 updates. By the time we reach 4.2.3 the battery life will be smoothed out
[Nexus 4 General] SammyK300:
Haven't been able to crack 3 hours screen on with Wi-Fi off in 5 cycles.

With Wi-Fi connected the whole time I nearly hit 6 hours twice.

Both cases have been 90% web browsing.
[Nexus 4 General] Serious_Beans:
Yeah hopefully. Until then...I'll just have to carry my charger around...thought those days were over lol. I know when Franco gets his nexus though I'll see some great battery improvements :D.
[Nexus 4 General] darkcurrent:
I don't have a data plan (only voice and text) and use wifi exclusively... does that mean this phone will give me 6 hrs of on screen time?

thanks

There's something seriously wrong at the kernel level on 4.2

A 2100mAh battery that pushes over 8 hours on LTE on the same hardware on 4.1 cannot have this big of a discrepancy. I turned GPS off and kept brightness at the lowest setting, and this is what I got. Screen on time was 1 hour 57 minutes and 36 seconds
[Nexus 4 General] aceo07:
Did you try without all your battery monitoring apps? That might be what's keeping it awake.
[Nexus 4 General] konfuzed:
from yesterday.. google now and nfc is off as I do not use those features unless need be. stock rom/kernel rooted.
[Nexus 4 General] TwinkyOfHope:
For what it's worth, I consistently get better battery life throughout the day compared to my parents ' and sister's iPhoem 5 :p they all turn off LTE, even though we don't get that service out here in Monterey.

Also, I use Google Now and location services etc. I think the extra drain is totally worth it. Still make it through the whole day.
[Nexus 4 General] dnlsmy:
Good call, I'll try that.

I use juice defender and use my phone average probably not touting that it is awesome just juice defender really helped my battery life
[Nexus 4 General] CrimsonDeath:
Hmm, not sure if that is also happening on the N4 - waiting for it to be available again here in Europe - but there were some issues with the Google Currents background sync sucking up juice on the N7...

For me, turning Currents backround sync off also improved performance, maybe that was fixed in 4.2.1 seeing that a few people are reporting improved battery life.
[Nexus 4 General] funkyblue04:
We need 3300mha batteries and a major focus on battery life.

Sick of phones like DROID DNA that come out yet battery life sucks.

Why can they not focus on battery life? I'm prepared for a bit thicker phone!

anyone know what apps are good to save battery? is juice defender ultimate necessary or don't bother
[Nexus 4 General] shawnaye:
Juice defender is the biggest scam in the world :D

Good apps to save battery are apps like:

XDA: Where you can simply scroll through interesting and amazing posts on the things that people do in order to achieve a better battery life!

Hmm.. I think this app is enough for now. Perhaps a better app will come out in the future.

OH WAIT! There's XDA Premium!

Haha. Don't have to buy any apps to save battery bro. Just gotta know what to do.
[Nexus 4 General] hallucynogenyc:
What, 55 hours, are you kiding me, I have to recharge it like 3 times in that period! Tell us more about your setup please.
[Nexus 4 General] nyijedi:
I have a question regarding battery health. I work in an office, so the majority of my time during the week consists of either sitting at my desk or sleeping (fun, right ;)). In the past, I've gotten into the habit of typically charging my cell phone either while at work or overnight while asleep - I wouldn't regularly do both. With the ease of inductive charging, I'm tempted to just put my phone down on a charging mat all the time while at work and while asleep, thus, having the phone charging/charged for a majority of my time. However, I'm suspicious that doing so may damage the long-term health of the battery. Are my suspicions correct?

I guess my question can be boiled down to the following. What general practice is better for battery health? Keeping the phone plugged in all the time so that it remains at 100% (which I assume includes a trickle charge constantly occurring as the battery bounces between 100% and a level slightly lower than 100%), or letting the battery drop down to 10%-30% before charging again?
[Nexus 4 General] pihx:
He's probably just using it lightly. Almost any phone can do that with light use. I have a Sony Xperia Ray with only a 1500mah battery and i can easily get 2-3 days on a charge with some to spare. I just use it lightly.
[Nexus 4 General] PhilipL:
Hi

Lithium batteries can't be trickle charge, if they are they will explode eventually.

The phone will charge the battery until it is full, then stop charging completely, no problem there.

The problem with charging all the time is you can get small top of charges taking place. It very much depends on how the phone charging system is designed. If after being fully charged the phone is then powered directly from the charger, the battery will stay at 100% for a long time as it isn't being used, if however the charging stops and the power is cut from the charger to see the phone powered by the battery, the battery will start to drop from 100% fairly quickly, at which point it will get a top-up charge back to 100%, and the cycle continues... Laptop batteries suffer due to this when you mainly use it on mains power, plus in a laptop the batteries tend to bake in the warmth of waste heat from the CPU etc, which they don't like either.

Lithium batteries don't like being at either extreme and it stresses them, and they don't like top up charges to full. For long life keeping the battery charged up to around 80% and never lower than say 30% gives you a lot more cycles, although as the run time is reduced, you are charging it more often so use the cycles up quicker! So the advantage isn't as great as you might think.

Really at the end of the day you are more likely to have a new phone before you have worn the battery enough to notice a reduction in capacity, so it probably doesn't matter at all. Just use it and don't worry about it.

Regards

Phil
[Nexus 4 General] golfinggino:
i was curious how much having the wifi on 100% of the time would affect the battery life, so i have been running the phone on wifi all day - at home and in my office and on my mobile hotspot when not in those 2 places, it is an average use day - few phone calls / texts / checking email / checking some webpages / xda app, etc. and the wifi certainly makes a big difference in battery usage. i am running jr2 rom with matr1x ver 1.5 kernel, i have also set the cpu in no frills cpu control to min 384 and max 1026, even with the cpu max set to 1026 everything is fast and smooth, the phone is now at 53% battery, it has been on battery for 9h 24 min, with 3 hours and 41 minutes screen on time, not bad - my mobile hotspot is lte and i get full bars most of the time so i dont really miss not turning on the lte on my phone this morning - this is the first day since last friday that i did not have lte running on the phone
[Nexus 4 General] tehrules:
My battery results. Seems to have got progressively better.

I use 2x Battery in night mode only, and I have advanced task manager killing apps when the phone sleeps. (Replicating the Motorola Atrix battery saving measures.)
[Nexus 4 General] ugotproblemz:
Does anyone else experience this?

Sometimes the battery drains REALLY FAST like ~2% within 10 mins..

Then...

On other times the Battery is stuck on [insert bat% here] and last FOREVER (like ~45 mins)

Note: this is all under normal usage...

anyone?
[Nexus 4 General] ra_grand:
Do you guys stop the cached processes too?
[Nexus 4 General] ugotproblemz:
Its just stored data (such as any save data for games for username and password for apps), shouldnt affect your battery. tho since the N4 is limited in storage clearing cache would be a good idea

3 Steps To Optime Your Battery

Disable your

Network location

locator. Disable all location service options in the settings menu.

Disable

Google Maps

. You have to follow the steps

here

, thanks to Karpfenhai's for the instructions of how to configure autostarts and the location service (you have to download an extra app)

Disable

Google quick search box

. Remove it from homescreen and disable/freeze it.

The step 2 is the most important, because you significantly reduce your wavelocks.

[Nexus 4 General] Serious_Beans:
My galaxy nexus with bug less beast and Franco kernel was giving me 2.5-3 hrs of screen time and lasted a full day idle. I'd get about 14-18hrs average. I think there is something wrong at the kernel level. New 3.4 kernel is suppose to bring big battery and performance improvements yet I don't see that with this phone as of yet.

[Nexus 4 General] PoisonWolf:

No way in Wonka hell will you get 7 hours of screen time under normal conditions. You must have charged in midway or you must have put in airplane mode and used it as a photo frame on 0% brightness.

Jr2 ROM matr1x 1.5 kernel, I am a heavy user compared to most was a typical day , texts few phone calls emails xda internet - lol any more questions !!! If you read my earlier post I was at 4 hours screen on time at 50 % battery 100% WiFi was the reason for this 7 hours screen on time
[Nexus 4 General] thegregulator:
This is my 3rd day using the phone. Rooted stock ROM/kernel. I was using LTE for about 13 hours (finally a perk for Canadian data users) and WiFi when I got back home from work. Automatic screen brightness. Google Now and NFC are disabled and Facebook/Twitter are set to sync every 4 hours. Other than that everything else is syncing normally. Two email accounts going. It's not groundbreaking but all in all I can't complain. My Galaxy S3 on LTE was about the same, maybe marginally better.

Update: Got it to 17h31m off the charger with 3h50 screen on time before the 4% warning came. Should add it was mostly browsing with some twitter, Facebook, xda, and a bit of words with friends. Could be worse.
[Nexus 4 General] Stretlow:
Not a chance, even if you had it at minimum brightness (please confirm what level) your not getting 7 hours screen on.
[Nexus 4 General] stuart0001:
What is it with Android Process?

I was going quite well today with 1hr:30m screen with 7 hours on with 60% left then I felt the phone getting very warm. So I had a look at system tuner pro and could see Android Process running at 100% cpu, phone was at 72 deg C and UI started to stutter when swiping etc. A few minutes later the phone rebooted itself and in the space of about 20 minutes it's gone from 60-30%.

My HOX has a poor reputation for battery but the N4 is at least 20% poorer at a guess. I'm going to try an exchange but I doubt it'll be any different.
[Nexus 4 General] golfinggino:
i never change the brightness it is about 1 cm from the lowest, i really dont care whether people believe my numbers or not - why would i lie about them ? you must not have your phone set up properly if you are getting poor battery results
[Nexus 4 General] Capt.PP:
From what I see, there are 3 ways to take on with these battery problems.

1. Wait and hopefully Google will iron these problems out by the time 4.2.3 rolls out. The battery problems, thermal problems or drivers are not up to date which cost low benchmarks, ect. All these problems surfaced on preview units and before 4.2 update. Most of us gave Google excuses saying it was not the final software, ect. Well, we have no choice to give them further time.

2. Do what alot of people are doing now by turning off most of the awesome functions of android such as down clocking, airplane mode on, turn off GPS, NFC, ect. (this option is very sad)

3. Buy a battery case to accommodate the heavy drain of power, hopefully Google will help with future updates. I plan on DIY one with 4250 mAh; Note 2's battery.
[Nexus 4 General] Younggun123:
I find myself questioning how accurate the battery monitor is. I just turned on the phone from a fresh reboot, Checked a few emails, updated some apps, looked at new xda posts ... about 10 mins of screen time. I then checked the screen time and it said 2:15. I know for sure I was on at least 10 min of screen. This isn't the first time I suspected it, just the first time I had fresh data. Makes me wonder.

2. Please be specific about how you've used it during the day.

Video, call, facebook, instagram, browsing....overall moderate usage​

5. Brightness, is it auto? custom? If custom, %? (thanks to Shadehh)

Its on Auto​

5. 3g / WiFi on? If yes for how long? (thanks to Shadehh)

I don't understand how people were getting this bad battery life from their galaxy nexus. Especially if they are GSM.

I have a galaxy nexus on AT&T, and if I don't use wifi, I will get 3 and 1/2 to 4 1/2 hours of screen on time (5 if i make the brightness minimum), and if I don't use the phone much, and only use say an hour of screen, it'll be at 75% after 18 hours off the charger, all on 3G, not wifi. I hope my nexus 4 will get me at LEAST that much. Yes I do have the 2000mah OEM battery.
[Nexus 4 General] calanizzle:
Since it's your first charge, I'm sure you're using your phone more than usual.

- It seems you have GPS on, I usually freeze maps whenever I'm not using it and defrost whenever I want to use. (I leave gps on for my Cerberus app)

- Facebook app it's the worse, it's a battery leech!!!!!!!!!!!

- Turn off Wi-Fi if you're not using it.
[Nexus 4 General] Monk4Life:
My battery is getting better and better with each recharge. 1 week after I got it and I can get over 4 1/2 hours screen on time. My Galaxy Nexus could barely get past 2 with the stock battery that came with the GSM model. The battery life is flawless for me.
