I do not agree.

In our world, we generally run on statistics. More specifically averages, if the average user experiences poor battery life than it is not incorrect to say the nexus 4's battery life is poor. Of course, there are always going to be outliers.

Plus, the average person doesn't know how to tinker with their phone in regards to custom roms and kernels. So the fact that so many people have to tinker or troubleshoot their phone to increase battery life is a clear indication to me that this phone has poor battery life. Also, everyone who tinkers with their phone or who is even on XDA surely does not represent the average population. So to generalize from the members here is absurd. XDA members are far more advanced, more knowledgeable, and better looking compared to the average person.

I love my nexus 4, but when you compare it to it's rivals (S3 and iPhone 5) the battery life isn't up to standard.

But, that's just my two cents :p
[Nexus 4 General] Mr.Mischief:
Just a quick word about battery life.

I've had many of the flagship devices. HTC One X, Galaxy S3, Note II, One X+, LG Optimus 4X HD, Galaxy S2, HTC One S, HTC Sensation 4G, Nexus 4(obviously lol), Meizu MX, and quite a few others.

Aside from the Note II, battery life has been about the same on all of those services.

2.5-3 hours of 3G screen time and 4-5 hours of Wi-Fi screen time.

All of my Samsung devices had horrible idle battery drain. Something like 10-15% I've 8 hours. My Nexus 4 lost 2% over 8 hours.

Running the latest version of Android is just icing on the cake.
[Nexus 4 General] gunster:
This thread is getting way too big for me haha. I tried going through it but it's impossible...so can someone compile like a short list of what can be done to lengthen the battery life?

I'm not complaining about it by all means, but I would love to know the common small steps people take, the best battery saver app that I can get that won't hurt my phone, or if even rooting it to get a new kernel is WORTH it for the extra screen time (i've kept all stock so far).

I know this thread is meant so you can find these things but...190 pages lol I would love for a battery guide to be written or linked to me if it already is and i just can't find it haha :(
[Nexus 4 General] Mr.Mischief:
Turn of GPS when you don't need it. Turning off auto-sync data helps a lot too.
[Nexus 4 General] canuckerr:
I am using Juice Defender at the moment and it has significantly increased my battery life, about 1.5 times the battery life from what it has calculated (seems about right).

The reason why juice defender works is because when your phone goes to sleep (ie. when you lock it) it automatically turns off your data and your wifi for a preset amount of time.

By turning these services off, it saves your battery quite a bit. The problem is you won't get any IM, emails, updates, or anything that requires data. Though, it will turn on wifi and data periodically. It is default set to 15mins. So that means if your phone is a sleep, it will only turn on your wifi and data every 15mins to sync emails, IM, notifications, etc. I currently have this set to 5mins, the min value.

So if you need IM, emails, facebook notifications, etc right away/instantly, juice defender is NOT the program for you. This is the only reason it increases battery life. I used to think I needed INSTANT updates and notifications, but in reality I don't. I value you my phone lasting all day, so I"m okay with my phone syncing every 5mins. I'm probably going to change it to every 15mins now. Less distractions, I don't really like checking my phone too often anymore.

If you unlock your phone, juice defender will automatically turn on wifi and data connectivity. Though, it will take some time before you regain connectivity. Just think if you were to connect/disconnect from your wifi. It takes that amount of time to do get your data connectivity back.

I don't mind it because I can get through the day now without my phone dying. So i'm happy and I guess I don't really need instant updates.

I'm pretty sure that The One S and S3 have better battery life than the Nexus 4. And android 4.2.1 is probably THE reason of the not so good battery life on the nexus 4.

one s was my device before the nexus 4 and battery life was worse.
[Nexus 4 General] Mi|enko:
But, when you consider the size of the battery in the One S, it was pretty damn awesome. You can't just say this device vs. that device. You have to take into account chipsets, connectivity, battery size, etc.
[Nexus 4 General] sucre213:
I've seen many review videos it seems gs3 is better than n4 as well as optimus G

Especially when playing games n4 according to my estimation It cost around 60% per hour to play large 3d games like nfc
[Nexus 4 General] CandyAndy:
SGS3 battery is maybe 15-20% better. Meaning that when Nexus dies SGS3 still has about 15-20% left with similar usage.

Of course these are just rough estimates not absolute facts.
[Nexus 4 General] cobyman7035:
Has anyone done 4g data test for battery. Life? I think 2hours max straight on lte 4g it will kill it
[Nexus 4 General] draugaz:
Quite possible, SGS3 display battery consumption is highly dependent on the displayed contents. Games, movies etc tend to have pretty low luminosity, so SGS3 is at serious advantage here.

The tide turns if you have something with a lot of black text on white background. Like websites, email etc. SGS3 (and any other amoled) battery does really suck on those workloads.
[Nexus 4 General] Mr.Mischief:
They really don't. I've had 4 Galaxy S3s and 5 HTC One Ss.

I'm comparing battery life of these phones, not the size of their battery cells or the specific specs. Basically, I'm comparing them like a non-techy person.

That said, you're right about the One S. It has like a 1650mah battery, yet the battery life is similar to phones with 2100mah packs.
[Nexus 4 General] barondebxl:
I've had one Gs3 and no One S. With the S3 I was reaching 5 hours of screen time stock. As far as the One S, I based my opinion looking at their battery thread in the One S forum. Also here are all 3 phones battery tested by gsm arena:

http://blog.gsmarena.com/google-nex...test-see-if-its-better-than-the-galaxy-nexus/

As you can see, the N4 isn't the best when it comes to battery life.
[Nexus 4 General] Mr.Mischief:
I'll take my real world tests over gsm arena.

My replacement Nexus 4 is about to arrive. Here are the last battery stats for my rev10.
[Nexus 4 General] dirtyhamster73:
My original n4 was a hw version 10, my rma is a hw 11 and it blows the original away in battery, by 5-6 hours. Whatever they did for hw 11 seems to have helped battery issues. I know others who have noticed the same results between 10 and 11.
[Nexus 4 General] barondebxl:
With all due respect, you were on WiFi like 99% of the time and no apps are listed in that chart.
[Nexus 4 General] Younggun123:
OK ... Dumb question how can I tell if I have hw10 or hw11? I'm suppose to get an RMA as well so I would like to know what I've got and what the new one is. I intend to rerun my movie duration test again with the same settings to see if there is a difference.
[Nexus 4 General] Mr.Mischief:
I used several apps, they just don't show up in that list for some reason. I wasn't on Wi-Fi the entire time, I just forgot to turn it off.

I listened to a couple of hours of Pandora, maybe an hour of YouTube, texting, Tapatalk, Maps, eBay, Amazon, Instagram, Facebook, and some Temple Run.
[Nexus 4 General] dirtyhamster73:
Fast boot will show the hw version.

Just got my new rma and its a hw 11 as well. With a birthday of 12/15 :D So it's 5 days newer than the rma I have now, which was made on 12/10
[Nexus 4 General] dcolaco:
Maybe this has been discussed here, but have any of you guys noticed that when on wifi and mobile data switched off, the battery life is greatly improved. I went from about 3-4 hrs of screen time to easily around 5 hours with similar usage everyday with google now, location services and autosync on. Not sure why this would happen since when connected to wifi mobile data should be switched off automatically.
[Nexus 4 General] Nathtech:
What do you guys think? Been on standby a lot today but used it quite a lot as well. No GPS, WiFi or Bluetooth, sync is on and so is mobile data.
[Nexus 4 General] dirtyhamster73:
What's your screen time? Judging by the percent doesn't look like you used it much. Click on "screen".
[Nexus 4 General] barondebxl:
That's pretty good then. The N4 does well on WiFi but not that good on cellular data.I still believe that the S3 has better battery life, it did for me at least. I used to reach 5 hours of screen time mixing WiFi and cellular data pretty much on a regular basis. That was stock. With my (2) nexus 4, the most I did was 5 hours of screen time being on WiFi all the time and lots of tapatalk. The battery definitely gets you through a work day but if you were to use cellular data only for a whole day, and if you were away from a wall charger, the S3 will be safer to have as it will give you 15-20% more than the N4.
[Nexus 4 General] dirtyhamster73:
Hoping to make it to 4 hrs. I think it will. This is with "KillRom" and Franco r34. No Bluetooth, GPS, screen all the way down, everything syncing except currents, Google magazines, movies, books and I think that's it.
[Nexus 4 General] dirtyhamster73:
My opinion is it's not that great. But let's see what others chime in with.

[Nexus 4 General] wtfshouldidonow:
If he charged a couple of times then we should be seeing some increases or mountains in his graph. The spaces in the h and the numbers depend on the font and/or language that you are using.

Now I'm not saying that I already do believe his stats, but if it is true, then kudos to you owner of probably the only 'battery issue-free' nexus 4!

But basically, our normal stats should be at around 5+ screen on time. A 28nm based chip? 2100mah battery? Vanilla android? It has got to be 4.2 and 4.2.1 just draining battery. Purely software. Remember the ios 6.0.1 fiasco over at the iphone 5 forums? (or was it 6.0?) Their batteries also sucked, but then Apple released an update and users reported a huge increase in battery life with their crap-phones ;)

If this can be done with software updates with a crap-phone, then we definitely are going to get an even better update from Google that would also immensely improve battery life. :)

Another one was the htc one x. When it was just released, people (including me) complained of the battery life. Our average of screen on was just 2 hours! But three minor software updates later and the average screen time was already 4-5 hours.

Just wait, and Google would definitely improve our battery lives with software updates too ;)

P.S Still waitng for my Nexus 4 here though :(
[Nexus 4 General] deepsunzhine:
Im not the only one getting this results with francos kernel...maybe u should go to his kernel thread and see some impressive results.....i used to get 4 hrs of screen time on stock kernel btw.....

Newbie here..just got my nexus 4, after unlock bootloader and root:

This is my battery trend.

- Only use for data (maybe around 30 mins for facebook and shopping on google store), display, games(15mins),

- Others will be messaging and idle, no calling yet

- Using stock rom and stock kernel

is this ok with my battery??

[Nexus 4 General] Younggun123:
You're on par for almost 6 hours of screen time which is well above avg. here.
[Nexus 4 General] tlslaj0417:
hmmm mean it is still ok?...because i am thinking of trying franco kernel r34...because i saw that there is good review on the battery stats
[Nexus 4 General] dirtyhamster73:
I'm on Franco r34 and you're getting better screen time than me. My screen shots are a few posts up. I feel Franco r34 has been the best for me as far as battery life goes. You want to give it shot then I say do it, see if you can get better... But you're getting really good battery life right now. A lot of people are getting crazy battery life on Franco, almost 6+ hours screen time, even have seen some getting 7-7 1/2. If I were you I'd probably stay put. That's just me though.
[Nexus 4 General] razball:
Your times are different in the top right ones 8 and another 1 ?
[Nexus 4 General] tlslaj0417:
hmm...thanks for your advice...but maybe i am not heavy using in this period...i am just worried that if next time i keep using data and play around will drained off my battery faster..so i would wan to try franco kernel....in case something goes wrong, i can just go back stock kernel from here (http://xdaforums.com/showthread.php?t=2024982) right?
[Nexus 4 General] Younggun123:
Hmmm something strange today. Got my best time ever and didn't change anything. Running stock with location turned off, everything else ... full on.

5 hours, 14 min screen. 14 hours, 45 mins total time on. 80% on wifi. Vast majority of use web surfing and email.

My norm is about 4 hours of screen with the same usage.

Wish I knew where the increase came from.

60% watching YouTube

20% Google +

the other 20% texting, making calls, surfing the web

[Nexus 4 General] stuart0001:
Another useful bit of info when quoting stats is the revision # of your phone (10 or 11 at present) to see if battery life is improved with the newer model. You can see this by booting into bootloader (Pwr & Vol-)

Could the OP please add this to the requirements in the 1st post please :good:

[Nexus 4 General] SkyBeam2048:
Good hint perhaps. Added information to my posted stats: Rev 11, CPU binning "faster". Flash size might do some difference in battery life as well, but perhaps not too much.

[Nexus 4 General] dirtyhamster73:
You're welcome! No problem. I believe, from testing both hw versions and talking to others who have had both, that version 11 is better on battery. Although there a couple of people who have a 10 and they get good battery life as well... So who knows! :D But the consensus says hw 11 has a better battery.
[Nexus 4 General] davidsteele1975:
Yes, I've seen that. It strikes me that it shouldn't make a big difference, though.

Just updated my One S to Jelly Bean do it'll be interesting to see how battery life compares...
[Nexus 4 General] SkyBeam2048:
You are totally right. I was used to UV my Galaxy Tab P1000, but at much lower offsets (-100 to -150mV). Now my "faster" binned Nexus 4 rev 11 runs stable at 1134 with 600mV while I cap the clock to max. 810MHz since I don't need more for my use-case. But runs stable in StabilityTest for many minutes on 1134MHz and 600mV.

Initially I thought Nexus 4 kernel is not supporting UV at all or values are just ignored since I capped to 810MHz and reduced voltages more and more without seeing a crash (was expecting it to crash already UV to ~700mV. I went on UV to 500mV over all frequencies and it did not crash a single time. Then finally noticed that it's documented at least for motley kernel to set minimum UV to 600mV. So I set all voltages to 600mV and found it crashing/rebooting at higher clocks. So I figured out voltages for higher clocks just in case I will re-allow them later.

Although it seems not to be uncommon that "faster" binned chips make up to 1GHz with 600mV. See here.
[Nexus 4 General] Evil_munki:
When underclocking the CPU does it increase lag or loading times perhaps?

Could it be that lg uses a different battery in version 11? A different brand maybe?
