Here's a food for a thought.

Most people recharge the phone overnight. As long as the phone can last 18 hours, then it can be recharged. I don't see the additional benefit if the phone can last another 10 hours because I'm not going to change the daily recharging schedule. Would you recharge every 1.5 days (morning/evening/morning)? If the phone can last a whole 2 days, then that's a whole new ball game but I doubt the technology is there yet.

I saw that Nexus 4 battery can take 800 recharges before degrading. So if I recharge once a day, the battery will be good enough for 2 years. Most people will get a new phone before battery degrades.

I have not tweaked my settings to improve the battery life. It seems most tweaking involves disabling some features. As long as it can last the day, I prefer to use all the features that N4 JB offers.

Of course, YMMV. Some people may be out of wifi network most of the day and rely on 3g, which consumes more battery. For them, tweaking may be necessary. But if you are in wifi network most of the time, why not enjoy the full potential of N4 JB?

I've managed to get my screen on time to 3 hours, which was my target however had to make some sacrifices.

Google Now disabled.

Disabled location services (detailed in the wake lock thread)

Dropped brightness from 100% (I like the screen bright) to 50%

Was getting two hours screen on before that.

Hopefully when the kernel devs work their magic (currently running trinity) I can get the same battery performance but re introduce some of the apps I've disabled.

I don't know about you guys but but I have to charge my phone twice a day because I browse in bed.
[Nexus 4 General] PoisonWolf:
Mostly HSPA. A little bit of WIFI in the beginning.

NFC disabled

WIFI location disabled.

GPS location enabled.

Syncing enabled.

Brightness at 10%.

Google Now disabled (don't use it).

Purely stock.

See attached. I think it faired fairly well. Able to reach 3 hours of screen on time which includes about an hour of Dragonvale (played it to run the battery to the ground to see how it held up). One thing that's really annoying is the thermal throttling. Dragonvale started choking after 15 minutes....not significantly to interrupt gameplay, but enough to know that it's stuttering for whatever reason. My Galaxy Note the previous night played Dragonvale for about 45 minutes and there was no choking, stuttering, etc. Constant performance throughout.

On a side note, I have a 1mm hairline nick on my bezel (the rubbery part) and I have no idea how it got there as it has been inside a pouch the entire time. Lol. No scratches on the front or back though. Odd.

I am with you 100%!! If this phone had some 1600ish mAh battery then I would never go for it. I have been changing roms/kernels 2 days now and I cannot see anything working fine. I mean this should be a problem with 4.2 cause it should juice out better than this. I thought it would be on the s3 level (I am not a dreamer to ask note2 's performance :P)

[Nexus 4 General] Heartbreak:
My last charge lasted me 2 days and 15 hours with 1.5 hours of screen on time. It isn't a lot of screen on time, but then again. I don't check my phone all the time. It finally died this morning when I was doing my morning TiBu backup.

I forgot to take screenshots but I can detail my settings.

NFC: Off (I don't use it anyway.)

Google Now: Off (I find it to be annoying more than anything)

Location Reporting: Set to my current location. (I hardly leave the city.)

Brightness: Auto

I was on WiFi a majority of the time but probably 4-5 hours were spent on data.

During the 2.5 days it was mainly used for text messaging (through Google Voice), Web browsing, Twitter, Facebook, and probably 2-3 hours of music through Google Music (Both cached music and streaming).

I'm running Xylon 011 (12/6/12) with the Kernel that comes with the ROM.

Hi

See my issue explained here http://xdaforums.com/showpost.php?p=35215730&postcount=20

I'd recommend if you are having battery issues to check the phone is really entering deep sleep, as battery statistics don't always show this information correctly.

Simple troubleshooting test: From the play store download CPU Spy. Run the application and from the menu zero the timers (Reset Timers). Now press the power button to sleep your phone. Leave for 30 minutes. Turn the phone back on, go back to CPU Spy and refresh the timers to get the latest stats. If all is okay your phone should show it was for the majority of time in deep sleep at > 95%.

If it shows no deep sleep state, but instead shows 384MHz for the majority of the time, you have a problem and this will mean battery life leaks away over the course of a day.

First, go into battery stats, the default android one is fine, and review the usage chart. Look at the Active bar, was this showing the phone was active during the test. Ideally this bar should mirror the times the screen was on, with only occasional appearances by itself when the screen is off.

1) Battery stats shows the phone was active/awake: You have an application causing the phone to remain awake, review your applications downloaded from the play store and check their permissions, and start removing applications one by one that have the permission "prevent tablet from sleeping prevent phone from sleeping", then re-test. This will identify the application that is keeping your phone awake, you can then either contact the author about the problem or remove it permanently. (Alternatively use an application like GSam battery monitor which will tell you apps keeping the phone awake.)

2) Battery stats show the phone was inactive: More tricky and I think this is a driver bug that hopefully will be addressed soon. My own thoughts from this issue is it can be caused by any application that has the permission "modify or delete the contents of your USB storage modify or delete the contents of your SD card". If an application keeps a handle on a file (keeps it open, perhaps logging something) it stops the phone from going to deep sleep from a lower level than the Android OS which means Android says not active, but CPU Spy says otherwise and the CPU remains active.

Hope this helps.

Regards

Phil

Screenshots are from my first full charge cycle. HSPA the entire time - no WiFi at all. Not happy, not unhappy. On GS3 I could get 4.5 with that usage. We will see if the nexus can match that after a few charge cycles. But frankly I don't expect it to see the 30% boost necessary to match that.
[Nexus 4 General] Stadsport:
Half way mark.
[Nexus 4 General] overlord727:
Does anyone else have any issues with the battery not charging all the way to 100%? I leave mine on the charger overnight and when I wake up, the battery is only around 92-93%.

I think the battery of my Nexus 4 is pretty awesome considering the price!
[Nexus 4 General] Jazd71:
I'm finding that it won't curve to full all the time, gets to 87% then doesn't go higher I have to turn it off then it will go to 100% only recently done started doing this no new software.
[Nexus 4 General] overlord727:
Hmm.. Well I let mine run down to 75% then tried the charger that came with the phone this time. It made it to 100% finally so I think it might have something to do with the charger I was using.

[Nexus 4 General] robstunner:
Maybe its just me but for a two and a half hour movie that sounds decent
[Nexus 4 General] nawoa:
Here's three tested use cases of mine:

1) Heavy browser/app/non-game usage mostly at home with WiFi on but a very poor HSPA cellular connection (around -100 dBm, 4 asu), it lasted 14h 0m 49s in total before I plugged it in at around 9% battery remaining, and the screen-on time was 5h 44m 10s. I'm pretty confident I could've kept the screen on for 6h but as you'll see in the screenshots, it was 3:25 AM by that point and I was literally about to pass out from exhaustion. This was after about a week of ownership I think, so if the "battery conditioning" thing is real, then I expect that I should be optimal at this point. Screenshot 1 - Screenshot 2

2) With WiFi turned off the whole time and a decent HSPA connection, I got approximately 1 hour with just Google Maps navigation, approximately 1 hour with Google Maps navigation and Google Music streaming, then another hour or so of screen-on time browsing or using apps. It lasted 7h 24m 41s in total before I plugged it in at around 4% battery remaining, and the screen-on time was 3h 7m 16s. Screenshot 1 - Screenshot 2

3) Just sitting idle on wifi with various services and apps synchronizing, I get around 1% battery drain for every 1-2 hours. No screenshots as I believe this is pretty typical.

I haven't tried playing a lot of consecutive video or playing a lot of heavy games back-to-back yet, but based on experience I can estimate probably around 4-5 hours of video playback and 2-3 hours of very intense games, 3-4 hours of more moderate games, or 4-5 hours of very lightweight games (Kairosoft games, Brainium card games, etc)

Overall this seems quite good to me. Coming from a Galaxy Nexus, ~6 hours of screen-on time plus another 8 hours of idle time is unbelievably good. I used to get around 3 hours of screen-on time under scenario 1, and around 2 hours under scenario 2. Idle battery life is "long enough" by my standards on either Gnex or N4, but I imagine the N4's larger battery would allow it to last a bit longer.

I find reports from people who say that their phones "don't last through a work day" a bit troubling. This isn't because I think the phone necessarily needs more battery life, but because clearly I'm in the wrong line of work if there are occupations out there in which battery life is the constraining factor in how much time I get to mess around on my phone. If a bare minimum of 3 hours isn't enough in a typical 8-10 hour work day - fully a third of the time you're being paid for - then I need to change careers.
[Nexus 4 General] hohoXD1233:
Wow your battery life seems so much better than mine, are you running any custom roms/kernels? Also, did you turn any settings off?

The iPhone 5 gets 7+ hours of screen-on battery life, so I'm reluctant to call anything short of 6 hours good.

[Nexus 4 General] Younggun123:
I'm getting fairly good battery life. Really good standby. The only things I have turned off are NFC and background location settings. 2 hours of screen time was plants vs Zombi's, the rest was surfing. Email accounts all on push. On WiFi 100% of the time.
[Nexus 4 General] chrisjcks:
Really,

Notice how all tests are with nothing using data?

Go check Netflix app and stream the movie..... Preferably by data.

I believe Apple enter a strict battery saving mode when running such tasks from media on the device.

Use data and the iPhone is one of the worst battery's, 1440mah or whatever it is, would never stand a chance.

Also,

When gadget show tested it, it was dead by 3pm.

http://gadgetshow.channel5.com/gadget-show/videos/gadget-test/christmas-high-end-smartphones

So, I don't understand how these sites are testing but it's not normal usage.

People at work are constantly charging iphones and moaning of battery life - whilst I steam all day and never have a problem with my N4.
[Nexus 4 General] undercover:
Guys, I found that using any swype like keyboard is really heavy on cpu and drastically increases battery drain. SwiftKey flow beta came second or third after screen. That's heavy.
[Nexus 4 General] chrisjcks:
That's weird, I'm using that beta and its never in my battery stats.
[Nexus 4 General] nawoa:
I suspect this is probably more to do with your specific usage pattern rather than the app itself. After all, the Android keyboard now includes a Swype-like function.

Same result. And I'm sure I don't type that much more than the rest of the people.

Ya but you have to remember my standby was 36 hours. If it was straight screen time it would have been between 5-6. For me 5-6 is very acceptable. If I'm on my phone screen for longer then 4 hours of screen per day I need to find a hobby.
[Nexus 4 General] Jayrod1980:
I think 5-6 hours screen time depending on usage is do-able and I personally have gotten close to 5.5 hours myself. The problem is if you have all your services on and leave the thing alone unplugged. The phone seems to only deep sleep 55-60% of the time. That's what sucks with 4.2 compared to my old Galaxy Nexus on 4.1. Google needs to get the wake lock issue under control. Trinity Kernel with Rasbean helped my on screen time immensely but it is clear that 4.2 is messed up. Hell, even on my wife's 4.2 Galaxy Nexus she get's an SOD requiring a battery pull about once a day. It's very annoying. Tomorrow I have to back up and wipe the whole damn thing and put 4.1 back on there. For an update, this one has been pretty buggy. The only device that doesn't seem to have a problem is my N10 but that doesn't have mobile data. I'm sure once they get 4.2 under control even that thing will gain some battery life (getting about 10 hours screen time).

[Nexus 4 General] dynamicpda:
I started seeing this today. I had been seeing a voicemail indicator and had ignored it for days. Today I called voice mail but didn't set the password or greeting, saving it for later. The rest of the day battery has been bad and it was only until after I got home, with the battery nearly drained, that I realized it was attributed largely to phone wakelocks. Then I called voice mail and set the password and greeting. I don't know the voice mail issue is coincidental. We'll see if setting things has cleared the problem.

EDIT:

I remember after writing this that I installed two programs today: EventBrite and Skype. Once I froze them both, the phone starting charging much faster, from 6 hr to full to 2 hr to full. I will try to narrow it down tomorrow. I will guess it is Skype because it is the communications program of the two.

[Nexus 4 General] raptir:
Honestly, even screen on time is a measure that can vary greatly from person to person. Playing a 3D game vs browsing the web or doing a puzzle or something. Browsing the web vs browsing local content (books, photos, cached pages through a website's app). Hell, even within browsing the web you could see vastly different usage scenarios. If I load a long page full of text once and read it for 30 minutes that's going to take a lot less battery than loading 60 short webpages once every 30 seconds.
[Nexus 4 General] GuyverV:
the great 4.2.1 battery conspiracy

i had to send my 1st nexus back because it shipped with a scratch. what i found in the 2 weeks that i had it was that the battery life was mediocre, at best. in a typical day, i would get 10hrs of battery with light to moderate use. i tried all the tricks except rooting and flashing a new kernel, because honestly, i don't think i should have to do that with a battery this large to get very good battery life.

my warranty model came this weekend and i decided to test (non-scientifically) how well the battery did if i ignored the initial system update prompt, unlike my first go 'round. i received it friday, around 7pm, and it was fully charged out of the box. i put a skinomi on it and let it dry over night. i began to use it over the course of the weekend, lightly on saturday and more heavily on sunday.

i would consider what resulted phenomenal battery life. here's the thing, with my first nexus 4, it would lose 15-18% battery life over night. with the warranty nexus 4, it only lost 4 percent over an 8 hour period while i was asleep.

for those who have yet to receive their nexus 4, i would seriously consider avoiding updating the software just to see how your battery life is. for my part, i'm incredibly disappointed that google shipped software that devastates the battery this badly. i'm hoping they come out with a fix it, mostly because i'm tired of the "system update available" notification and because battery seems to be the major gripe of many users. if someone has similar results, i would love to hear them.
[Nexus 4 General] ksc6000:
You call this phenomenal battery life?
[Nexus 4 General] GuyverV:
i would consider 1 day 9 hours and 9 minutes of moderate to heavy use a marked improvement over 10 hours of light to moderate use, yes. the bottom line is that the phone does a poor job of idling/sleeping if you accept the update that comes out of the box
[Nexus 4 General] ahalford:
Guys, you're *****ing too much. Looking at posted results, there is an average of 4 - 4.5 hours of screen time per cycle, which is very similar to Galaxy Note, 5.3 device with 2500 battery. It's not phenomenal, but it is very good & solid result.

P.S. I would kill by napalm every "reviewer", saying in the review "This device lived 8 to 10 hours", without being fxxxxg specific even a bit.
[Nexus 4 General] lazer155:
After 3 full charge cycles the highest screen on time I have gotten is 4 hours 15 minutes. It is stock and rooted. The only apps I have installed are evernote and skitch. Maybe it needs some more charge cycles? It's not anywhere close to the 5 or more hours a lot of other posters have reported. I think it's better than my ipod touch 4th gen was though so that's good.

This is my first smartphone by the way. I previously had a galaxy tab (first gen from samsung).
[Nexus 4 General] ksc6000:
Terrible standby life on this stupid phone. Screen has been on for 12 minutes (texting and picking ringtones from the default ones) at this point at about 5 (yes five) percent brightness. GPS and all location off. Sync off. You'd think I'd have to have brightness at max playing a 3d game for the twelve minutes for it to already be at 90 percent. My galaxy nexus by this time with this kind of usage would be at 95.
[Nexus 4 General] raptir:
For every person who has reported 5+ hours there are four who have reported 3 hours. As I mentioned on the last page, it's nearly impossible to compare usage across different users. My web browsing habits could be different from your web browsing habits, my gaming habits different from your gaming habits, etc... 4h15 is respectable battery life depending on what you are doing with it.
[Nexus 4 General] ne us:
The battery is really disappointing...
[Nexus 4 General] lazer155:
I was browsing with chrome primarily, looked through the play store for about 15 minutes (didn't download anything, just searched), and opened evernote 2-3 times. Each time I was done with one of those 3 things, I closed it from the recent applications button. I don't understand how those few people are getting such great battery life. It's really good. It does seem like more people are reporting closer to 3 hours. I was just hoping mine would get better after a few charge cycles and that it isn't defective. I should probably mention that I have all the stock sync settings (haven't changed any of them, whatever was on is still on). The only thing I did change was disabling google current's background sync. However when I got my highest screen on time, it was on.
[Nexus 4 General] droidd3v:
just as an experiment, I charged my phone up and rebooted my phone and then turned off wifi, GPS .. there's no sim in it too.. (still waiting for a stupid micro sim but that's a different story)

I must have done this at around 11 last night and this morning when I woke up about 7ish, the batter had drained to 98%

From this my understanding is that the OS itself doesn't eat up battery. So does it make much sense to be hoping that a software update will minimize the 'battery issue'?
