Hey Guys,
A bunch of people are complaining about the battery life on Nexus 4. I've been waited for a couple days since I got the device, to have enough confident about the battery before I make any post here. Yes, the phone battery drain pretty fast on the first few cycles. After a bunch more charges later, let me tell this, the battery life did get significantly better. It lasted about 10-15 hr depends on the load of the usage.
Here is my typical day, off the charge at 100% in the morning, listen to a few songs, checking emails, and messages while getting ready for school. About an 30mn to 1hr of internet browser and youtube videos while on the bus. By 1-2pm the battery drop the about 70-80%. I put the phone in silent mood til i'm done with all my classes. On the way back home on the bus, I listened to a bunch of music, web browsing, maybe a few phone calls, texts or games.
Compare to my old phone, Samsung Galaxy S2 T989, im impressed with the Nexus 4 battery life. My Galaxy S2 battery always die on the bus coming back home. What I'm trying to get at: if you're a light to medium user like me, then get this phone. I was hesitate at first because I always have bad experience with android battery life. But Google seem to get its OS right with this nexus device, mainly because the battery drain minimum while in sleeping mood.
Can you post your Nexus 4 battery performance screenshot if you have been using the phone for more than a few days ?
Is there supposed to be a question being asked? Or a statement as this is in the Q&A forum.
I agree with you on many points. People need to wait at least 5 to 7 days for the battery charge to fully kick in. The first days mean absolutely nothing as it is still being aligned plus the user is still installing apps and setting up their phone.
There are some notable problems in the default kernel that uses more battery Usage than normal too.

From full battery to this overnight + breakfast usage. Rasbean + Matr1x v3.0. Never seen anything like it. Coming from the GN, this phone is a different dimension altogether. On any aspect..
Had phone for 5 days. Drained phone to 10% then fully charged. Moderate to light use made it through a day.
Stock rooted + Franco Kernel.

Depends on how much screen time you got, which you didn't show us.
The trick is to be careful about using mobile data when signal is bad, I switch to WiFi when home to avoid unnecessary battery drain.

What is this obsession for battery life, it lasts me well through the day with moderate/heavy use. I charge it at night (if needed) and unless you are homeleless this shouldn`t be a problem. It`s a great phone and i enjoy using it.

I thought the same until my N4 actually arrived, it seems battery life is abysmal compared to my Optimus 2x which didnt have anything really spectacular in regards to battery size. On my O2x I could get 1.5 - 2.5 days depending on use, hitting atleast 1 .5 which was good and acceptable for me (I can charge at night anyways) however my N4 doesnt even reach 13 hours on similar usage!.
I am quite a light users of smartphones however I do like to have a power phone when it comes to using it on the basis of smoothness and capabilities if I need to say do work on my phone, I rarely play games though. Main usage is 2 email accounts on poll 1 hour steps, a third account that is an exchange server and polls in 30 minute steps and thats about it with some brief browsing and a handful of texts (been a quite time since I got my N4), this is less usage than my O2x and yet it still performs alot worse!
I was hoping of staying with stock as I was expecting it to finally be good, comparing it to LG stock attempts it is but battery life isnt . I will be trying the combo Vangelis13 mentioned, raspbean and matr1x kernel as that seems like a great mix however Parandroid has been on the table and it seems like alot of being are getting good results so I will try it soon .
If I can get more than a day of usage I would be really happy, if I was playing games or doing really heavy tasks I wouldnt expect it to last but right now it is doing pretty much nothing and dieing far to fast!.
One thing I've noticed since coming to N4 from S2 is that phone calls drain battery much more significantly on the N4. I could make an hour long call on my S2 and it would use no more than a couple of percent battery but the N4 used 15% for an hour long phone call the other night.
If I didn't own a nexus 4 and came to this thread to find out about it's battery life I would expect it to be good.
Point is you guys are misinforming everyone. The battery is mediocre and that's it.
It won't last a full day if you use it constantly and I do need two charges / day many times.
Let me put it this way, you will only get roughly 3 hours of screen time on stock everything. If that is good for you then it's will have good battery life, if not then you will say it's got poor battery life.

There is nothing subjective about 3 hours screen time.

you are perfectly right.
I come from an iPhone 4s, which I changed because the battery life wasn´t that great and I thought it was time to try something new.
Got the N4 last friday and played around with it during the weekend.
Monday, tuesday and wednesday this week... none of these days I´ve been able to come back home with the phone still on.
I wake up at 7.30am and I usually am back home at 6pm.
In my opinion, and honestly should be in everyone´s opinion, 10 hours of battery life are unacceptable, whatever the usage is (considering that 7.30 of those 10 hours I was at work)
I have till friday this week to return it, which is a pity because the phone is great
i get 5-6 hours sot..
rom is omnirom 5.1.1 hellscore kernel b73.
100mv undervoltage hellsactive governer.
think 7 would be possible if google services would not take a quarter of the battery.
the screen is not taking that much battery as one would think.
think most issues with battery life come from fake original battery replacements.
had 3-4 sot using "original" battery. but after replacing with real genuine from official lg spare parts shop 5-6...

After using CM 10.1 for the last two weeks and loving every second of it (including the unbelievably impressive battery life), I regretfully had to return to a stock ROM to avoid outgoing call audio bugs that were interrupting my phone's use for my job.
Out of curiousity, what kind of battery life is the typical stock ROM user getting? On CM 10.1, I was getting almost 4 hours of screen on time with 40ish percent battery left by the end of the day. What can I expect with stock TW?
There's a thread somewhere in here that talks about battery life and I'm seeing most people get between 3 and 5 hours of screen on time. A few people have horrible stats at around 1 or 2 hours, a few get 6+, it just depends on what you have installed, sync etc, and how you use your phone. Personally I average 3 1/2 - 4 hours on the stock ROM with Gmail, Facebook, Instagram, and a few other small things syncing.
Im running stock rom rooted with awesome battery life 5+

I'm currently on deadly venom v 8.2 on mf3. I only get 2-3hrs screen time w this device. I already greenified all everything connected to Google like maps, services, search, etc. I hate the fact that you even have to do that just to maximize battery life. I don't like turning on and off stuffs like location services, blue tooth, and wifi. I always leave them on. I hate the fact that you need to lower the brightness or readjust the brightness again and again just to increase battery life. That's a no no! I have bad eyes, I use lux dash as my auto brightness. I don't have any background widgets on my phone. My home screen is just filled w apps (no widgets) because they say widgets eat battery. My phone can last the whole day when it's on idle. Battery is 3-4.5% per hour when on idle. It balloons to 15%—25% per hour once I start using it which is very annoying. These are the only apps I use and I always close them all the time. Instagram, Facebook, Twitter, viber, Google voice, BBM, Gmail. What can you guys suggest to improve battery life? I don't believe people saying that they last 2 days or even the whole day. That's complete BS. I'll attach a screen shot on from better batter stats when I started making this, I started from 100%
12% in 33mins. Geeeez

You might want to get a new battery... My phone is running Graviton and I have excellent battery life. I keep power saving mode on, use Greenify, turn off Wifi, GPS, and Mobile Data when NOT needed. Generally I push at least a day and a half out of this stock battery before doing a complete charge. I try my best to not let the battery drain 100%.

If it went from 100 to 12% in 33 minutes you have a bad battery, plain and simple.

Right. Bad battery is very likely. That and should be using better battery stats to get a picture of what's going on.
It's not the phone and naming the ROM as if that has something to do with it is bad form.

What he said. I am stock but rooted and using Juice Defender, Greenify, toggling gps and mobile data off etc, I get full day on high usage and 28 hours on light usage. Must be a bad battery.
Meh, did some math. 12% in 33 min did cross-multiplication for 99% battery used, got 272.25 minuets divided by 60 to get an hourly total. You'll be getting 4.5 hours on screen time.
I don't personally think that's bad. Did some more calculations for Nexus 5 on battery. Heard it's getting about 3.5 hours screen on time, so with that to get your 4.5 hours screen on time the nexus 5 would need about a 2960mah battery.
Well, firstly, you should believe that some people's last 2 days or so; as I've seen photos posted by "battery life enthusiasts" in the better-battery-stats thread and other places showing it's possible. 12% in 33 minutes isn't that bad and is around a stock TW battery expectancy.
You're on MF3.. which means you cannot run an AOSP rom, so almost anything your running isn't going to be extremely lightweight for battery. ALL TW based roms will drain battery more than a single AOSP or GPE rom, as the system is a lot more heavy.
I greenify anything associated with the google-cloud or push-notifications, if I want to know my Facebook updates I can click on the app myself. I have location services turned off because there's ZERO reasons to use it unless I have a need for my GPS. Do you know that MANY apps use your location service even when not running and cause constant wake-locks. I've also moved my Google Services Framework from a system app to a user app with Titanium Backup Pro so I can greenify it and completely disconnect myself from Google if I have no needs for the play store or push-notifications. Gmail and gmaps can still run independently fine without the Framework, the GSF is also a major cause of wake-lock battery drain. Even if you greenify google apps, the GSF is still going to cause numerous wake-locks and affect battery.
I don't have a photo at the moment, since my phone is plugged in all the time anyway (just to keep it topped off), but I've had it run for almost 2 days without charging it; with occasional screen time, gaming, and having it idle. I'm also on a non-TW AOKP rom that's very very lightweight.

Here is my battery so far. As you can see, it barely has been used since yesterday. Screen on time is 25 minutes. Wifi is always on and I weather widget reloads every 4 hours. GPS is off though. Obviously, it lasts slightly less than a day if I use extensively with games, web browsing, email. Considering how much I usually use the phone, it does last 2 days.
Im on MF3 and using Wicked rom with SS.
If you get a new battery....
If you are thinking about getting a new battery and don't mind the extra bulk, go for the 7500mAh Zero Lemon Battery. I got one over a month ago and it will EASILY get 3+ days of battery life. It will add a lot of mass to the phone, but if you are looking for stupid battery life, check it out. Right now I have 26 minutes of screen time and 92% battery life left. It's been off charger for over 8 hours.

Edit: Forgot to mention I'm Full Stock / Full Lock.
I have noticed the standby battery on this phone is AMAZING!... but the screen on time is horrible for me too :S... can barely get 3 hours and that is with like 30% brightness... sigh
people said amoled helps save battery... but i used to have muchhh better battery with my htc one
So these are my stats on very light usage. Very good idle time. Just 2.5 hrs screen time

Hi all.
Just a quick question. My battery life is great but i feel like it could be much better. Here are my current stats as i write this.
With this its saying i will get under 4 hours screen on time, i wouldnt say i was a heavy user. I use my phone quite a bit but i wouldnt say it was alot.My biggest problem is with the android system anyone else have it as such a big drain? Somedays its sat up at 40%
Anyone know what i can do to rectify this? Im currently not rooted..
Thanks in advance
Liam
There are just two possibilities.
LG stock rom is so bloated that it sucks most of battery or GRAM feature is so good that screen time is not really problem anymore.
Forgot to mention, my screen time was 2hr 30 so probably looking at not even getting 4 hours screen on time.. Gonna have to guess that it's the stock rom sucking up loads of battery? Would that cause the android system percentage to be so high?
I'm having the same issue here.. Getting 4 hours screen ttime though...

install greenify. it save my battery. last longer.
I can easily reach 6 hours screen on time. And I'm a heavy user and by no means try to save battery. multiple social networks, emails syncing etc often streaming music and watch videos and brightness set to a constant 75%. This is on StockModRom. So yeah I'd say something is draining your battery unnecessarily there.

Strangely, for me, when I go over ~2h screen time the Android System drain is taken over by the Screen drain. This being said, I never got over 3h30m of screen time - this is with about 10h WiFi (including overnight => ~2% drain) and about 7h 3G. I have noticed plenty of crap among the kernel wakelocks, but I lack the knowledge to remove them in the source code and rebuild the kernel.
Also, BBS is among the apps that trigger a Qualcomm bug regarding sensor kernel wakelocks (sns_async_ev_wakelock), which, obviously, lead to more battery drain.
All of this is not really acceptable coming from a company like Qualcomm (the sensor bug, in particular, is present ever since the S3 QC version...).
I'll second that Greenify is pretty good at saving battery.
I too have had a screen on time of 6 hours 11 mins over a duration of being off charge for over 14 hours
I'm using StockMOD kernel but the ROM itself is stock as i can't seem to get StockMOD rom to boot.
Also if you Root try TricksterMOD and use multicore savings etc maybe get a bit more life from your battery
Hope battery life gets better for you as it is an awesome phone would be nice for you to enjoy it as much as the rest of us

Wow just wow. This was my last charge, absolutley incredible.
This includes 1hr 45min of music streaming.
Streaming a 2hr 20 min film.

Smashed my phone's screen back in march and only just got it fixed the other day. One of the first things I did was upgrade to the latest purity ROM, based on 4.4.4.
I am getting terrible battery life, only about 2-2.5 hours screen on time over 12 hours and it's dead - thats mostly on wifi with about 30 mins on spotify. I have google now switched on, but location reporting off. Brightness at 50%. Hellscore kernel.
Is this a known issue or is there something up with my phone??

I am on cm11 and matr1x kernel and it runs for about 4 hours with 3 hours screen on time. I am surfing the internet right now, listen to music and doing whatsapp a little bit.
If you have newly flashed your rom, you should let your phone settles for a couple of days. The batterie is always worse after flashing a new rom.

not true. VERY not true. its your own setup that's destroying your battery. battery life is mainly determined by how you yourself use your device, how you ser it up, which apps you use, and very much your data/phone signal. i, personally see 5-5.5h screen on time every day, witjout disabling anything, and on lte. hows that horrible battery life? learn to set up your phone, or change your rom/kernel. the n4 is not known for horrible battery life. and battery life isnt generally worse after flashing a rom. where you get your information from is all based on speculation, not on truth.

I am sorry. It is just, compared to other devices the nexus 4 is rather under the average. I myself am very satisfied with about 4 hours screen on time. I dont know how you could even get 5 and more. So, master, if you would kindly share your wisdom with us, we would be very glad.
But lte and nexus 4? That screams after horrible battery life, but tell me your story.

I'm on L at the moment, was on 444. I've never ever heard of a battery bug in 444. the one thing that will decide the battery life of your device, that you don't have control of, is your data/phone quality. it can make a phone get great battery, or keep it at worse battery life no matter what you do. the quality can make or break battery life. also, I've found that I get much better battery life on lte as opposed to 3G/H+. with H+, I see around 4h sot no matter what, with lte I see around 5h sot. also, screen brightness can make a big
difference. I normally keep my brightness at about 25%. if I raise it to 50%, I'll get about 45 minutes to an hour less in screen on time.
