[Nexus 4 General] stinky73:
Especially reviews from Engadget who resemble apple fanboys more and more with each passing day! Their "review/ test" of nexus 10, for example, seem to completely contradict many tests from other sources.... for them the battery life was one of the "cons/ against" points.... other tests have listed battery life in the " pros/ for" section... take it all with a pinch of salt until some real user experiences can be used as a reference point.... half of these reviewers have vested interests and clear bias as well as many of them being semi-illiterate ( or should that be semi-literate?) people who think they are better than they really are....
[Nexus 4 General] mesasone:
Seriously. I'm really looking forward to this phone, and will probably to pre-order one, but these issues should not be appearing at this point in the production/launch schedule. Google has, well had, complete control over the launch timeline... they could have given it a few more weeks and worked out the kinks. But instead it feels like they are pushing it out the door prematurely.

That is fine, but the launch date is less than two weeks away. Major issues like this should have been sorted out weeks ago, and this device should have never been sent out to reviewers if it was in an unfinished state.
[Nexus 4 General] yahyoh:
did u see slash gear review ? ( chrome is freaking laggy >_< )
[Nexus 4 General] TheBrandonWRX:
No ****. Google released review samples. Bad decision.
[Nexus 4 General] MizuhoChan:
This means nothing to me. I use my phone next to a computer most of the time, so I could just stick it in the usb, or maybe even get a portable battery charger thing. But I highly doubt it'll be necessary, what with the software not being the final version. Maybe a bad decision, but if they wanted to release it when they did, they had to send out some to get reviews, even with an earlier version.
[Nexus 4 General] r0cafella:
Maybe all is not lost on the battery life front guys.

Phil Mickinson from Android Central posted this video about the new quick settings. He also goes into the battery menu @ 1:05.

There's no detailed breakdown but from my eyes all is not lost.

http://www.androidcentral.com/inside-android-42-notifications-and-quick-settings
[Nexus 4 General] eep2378:
Yup. Final software has yet to be released. Chrome is laggy as hell on my S2 and many other phones.
[Nexus 4 General] ksc6000:
People are missing the point of this thread. BATTERY LIFE. We all know benchmarks can improve with more optimized software.

The fact of the matter is the 2 websites (engadget and anandtech) that did actual, quantifiable battery tests show the battery to be abysmal. The verge did not give any real specifics so their battery life claims are meaningless!

The fact of the matter is, this phone is getting 5 hours of video time vs the optimus G getting almost nine!

There is something seriously wrong here because unless this due to a massive bug, this will not change. People have tried to increase screen on time on the galaxy nexus and by and large it's not worked, because the screen will draw what it needs. Period.
[Nexus 4 General] Monkeybrew:
76% left after 7+ hours? Nice.
[Nexus 4 General] Venekor:
It benchmarks the same as the dual core versions of the CPU...

It has to have a dual core inside rather than Quad or two cores disabled at least because it cannot be a coincidence that it's only delivering dual core power.
[Nexus 4 General] draugaz:
Exactly. It is beyond me why engadget insists on using such a lame battery test. Unless they cater solely for persons using their phones as PMP's and nothing else. Or are paid by Samsung :)

"50% brightness"? From what? How many nits? It is like testing a car mileage "at 50% of top speed". Where one vehicle will be barely moving @ 50mph and another will go 100+mph with obviously different fuel consumption rate.

Most Amoleds reach around 250-300nits max brightness while nexus4 is almost twice as bright. Ergo - tested at double brightness. Is it fair?

More, it is not a secret, that typical average pixel brightness in a movie is something like 30-40%. And in a typical web page (black text on white background) closer to 95%.

It is also a hard fact, that AMOLED power consumption directly depends on the pixel brightness, while LCD power consumption is more or less constant. AMOLED usually consumes maybe a half of comparable LCD on said 30-40% brightness and twice as much on the 100%.

So, such movie tests inherently favor amoled screens. For a PMP use case - fine, for anything else it is completely meaningless if not misleading.

So it is not a miracle that OneS and SGS1/2/3 shine in this kind o tests. And at the same tame suck for such things like email/browsing.

Then there is second component - a video decoder. How is the movie coded? In case of iphone there is not much choice, itunes guarantee that everything is perfectly aligned to match the hardware decoder, so the CPU can mostly sleep. What about the android? Was the movie coded in a way which is suitable for available hardware decoder? Or much of work is still done by a general purpose CPU with obviously higher energy consumption?

If you are testing a PMP - fine, it shows where you are at in respective ecosystem. But as a general test it is quite meaningless.
[Nexus 4 General] chrisjcks:
Of course its software, you just said it yourself.

The optimus G has same battery, screen & CPU/GPU - right?

It even probably has same ram.

Also, the optimus G has battery bugs regarding software too says LG, yet it still got 4hrs or so more.
[Nexus 4 General] wngmv:
Yeah. It was worrisome. but I am still waiting on some other review sources that I believe. But I have got used to the abysmal battery performance of Galaxy Nexus, so it couldn't be worse here.
[Nexus 4 General] draugaz:
Or rather there is simply not enough work for 4 cores. Maybe even not enough for 2.

Contrary to the illusions of the spec freaks, most of the real world software is strictly sequental thus can't be meaningfully distributed among more than one CPU.

An analogy for non programmers: it is like driving from city A to city B. Having two identical cars in your garage won't make you any faster than just only one.

Ok, there are other "housekeeping" tasks (like garbage collection, JIT, caches etc) which can be meaningfully moved to the second CPU, so moving from single core to dualcore is really noticeable and brings real performance benefits. But that's about it, moving beyond dual core currently does not add anything on top. The additional 2 cores will be mostly idling and sleeping. Which is apparently the case in those "tests".
[Nexus 4 General] wurzelsepp3:
I think you are missing the point, the Optimus G has the same battery the same screen and overall the same hardware, why on earth shouldn't the Nexus 4 achieve the same battery life once the software problems are sorted out.
[Nexus 4 General] Monkeybrew:
Indeed. Which makes it so weird that the Nexus benchmarks are so different. Mysterious, even.
[Nexus 4 General] yahyoh:
HMM :rolleyes:
[Nexus 4 General] Basil3:
I'm sick of my one x, mainly because flashing ROMs is a nightmare, jellybean upgrade is a mess, and battery life is average. I was gonna sell up and switch to the Nexus 4.....until I read this thread :(

Guess I'll just wait and see what happens when real users start to use it in the real world.
[Nexus 4 General] GMArthur:
Anandtech battery tests are performed according to nits (calibrated to 200 nits) and are not based on movies but web browsing on both LTE/3G and wifi. Battery life compared to almost every other top phone is horrible. As somebody who was planning on getting a N4 on day one this will have me waiting and or possibly getting another phone. Doesn't matter how smooth the UI is or if it's running LTE or 3g - if the battery is dead none of that matters.
[Nexus 4 General] yahyoh:
LOL we have an Arabic Proverb say : '' staying with ur monkey better than getting

monkeyer one

( Worst one ) "

edit : its mean like stay with ur bad thing is better than getting the worst
[Nexus 4 General] eep2378:
You don't think buggy, pre-release software will/can result in poor battery performance? Lets wait until the device is released with more information regarding battery life.
[Nexus 4 General] huntedsoul12:
Product might be final but software isn't, get your facts right.

And I dont think you are that ignorant to not to see that those reviewers ignored software update and continued testing, while the update prompt was dangling on the notification bar.. lol

Thank you
[Nexus 4 General] ksc6000:
Agreed. Or I'll stick with my galaxy nexus with the 2000 mah battery with my external charger with my spare 2000mah battery so I can swap it out if I need to.
[Nexus 4 General] SubyWill:
Engadget is a joke.
[Nexus 4 General] throwback1718:
I hate to be the one. But I'd be happy with 5 hours of screen on life. My Current GNex gets about 3.5 hours

Anything is an improvement. 8 + hours would be great but I'll be tolerable.
[Nexus 4 General] darkgoon3r96:
Anandtech, CNET, and Gizmodo aren't.

---------- Post added at 06:14 PM ---------- Previous post was at 06:13 PM ----------

It depends on what you are doing! This is video playback.. I can get 5 hours on my SII if I do easier tasks with darker backgrounds
[Nexus 4 General] phositadc:
People, 5 hours in the video run down does NOT equate to 5 hours screen on in real life usage, fyi. It probably equates to LESS.

Edit: because in real usage your screen is not on 100% of the time, so idle and standby end up consuming a lot more power than in these artificial video run down tests.
[Nexus 4 General] manlisten:
From 9 to 5 Google:

Not exactly scientific but another conflicting perspective nonetheless.
[Nexus 4 General] TECK:
That video was done on a pre-release Android OS. Pretty sure the battery specs are wrong.
[Nexus 4 General] immunityx:
And all the other reviews ignored the update too right.....
[Nexus 4 General] bozzykid:
They are running close to the final versions so people expecting magical improvements to battery life after the final build is released are probably going to be disappointed. Maybe their phones were faulty, but I wouldn't get my hopes up that an updated build is going to be a major improvement.
[Nexus 4 General] yahyoh:
WOW screen look amazing :victory:

Damn the verge review ( he said screen colors washed out :cyclops: )

edit : here some teasing pics :p
[Nexus 4 General] Pragmata:
I don't really have a bone to pick in this fight (anything is better than the 1 hour screen time I can get on my Galaxy S2X; no video, just regular use), but I'm kind of hoping that upon release it's DRASTICALLY better because I want to see the social reaction on this thread and see if anyone who is vehemently hating on this device because of this actually apologizes or acknowledges they were wrong. Again, not because I want it one way or another, but from a social perspective it's always the ones who cry wolf that never have the guts to admit they were wrong. xD If they are right however and battery life doesn't change, I expect a lot of "TOLD YOU SO" or "HAHAHAHA LOSERS".
[Nexus 4 General] leventccc:
You are right colors are really gorgeus

Look at this photo. It is the highest res photo of nexus 4.
[Nexus 4 General] Anubis007:
no body expected the benchmarks to be that low either especially that it's proven already to be the fastest chip on an Android device now. the software is not even 4.2.1 (expected final release version), we are not sure if it's the final build. if Galaxy Nexus owners are reporting improved battery life on a 1750 mAh battery with Jellybean 4.1.2 then you really think Google would take a step backward software wise?

Edit:

actually, i find the SLCD2 on the One X to be a tiny bit more saturated than the IPS+ on the Nexus 4. definitely on the top of best screens but it doesn't hold the title for me.
[Nexus 4 General] Rusty!:
That's not a photo, it's a render.
[Nexus 4 General] leventccc:
You are right, my mistake :rolleyes:
[Nexus 4 General] Red Wolf:
watch this podcast guys http://www.youtube.com/watch?feature=player_embedded&v=KlOVmk80NuA
[Nexus 4 General] wreckone:
I certainly have my hopes up that the final build will achieve respectable battery life. I had to upgrade my GNex battery to 2000mah to get thru a day comfortable with moderate use. It will be interesting to see all the reviews I'm really curious about the benchmark results it should be up there with all the other quad core devices.
[Nexus 4 General] Basil3:
For those who don't wanna watch the whole hour, they talk about battery from around 9:30. Approx 4.5 hours screen on over 18 hours on wifi, so about similar to my one x. Hopefully this will improve.
[Nexus 4 General] VictorNYC:
Ooook that's it ! That does it ! If this beautiful and insanely cheap phone doesn't give me AT LEAST 8 hours and 1 minute of continuous movie playback I WILL NOT BUY IT ! I demand THE very best for the HUGE amounts of money I will be paying for this phone ! I mean I DO TRUST way more those TOTALLY unbiased reviews from those self proclaimed geniuses at CNET and Engadget than anyone in LG or Google itself, hey Google doesn't even know how to write a Kernel or a Rom so how would they even figure out how to fix it ? I DEMAND the same SPOTLESS track record that Apple and Samsung have ! Everybody knows they WOULD NEVER release an unfinished product or software before it was 100% ready !

C'mon Guys !! Really ? Really ???
[Nexus 4 General] mazurson:
3.5h was the best I could get with my One X (I only used jellybean though) :s

so 4.5h would already make a differnce to me
[Nexus 4 General] Zurginator:
Anything is better than my current 1 hour of screen-time battery.....
[Nexus 4 General] Frunobulax:
Moderation said this should also be discussed here.

I'd like to comment and ask about the video recording.

It has been shown that the camera is only able to do 22fps 1080p recording. A result as bad as the HTC One X, that promised the world, but goes around that frame rate, too.

The first and only defensive argument is that it is "unfinished software". Look, software can't do miracles. It has been proven - remember the first Nexus 4 camera photos that floated around? They were somewhat subpar, and quality has not improved since then.

They can't do a miracle like stabilizing frame rate in 2-3 weeks. Not only they can't, they mostly WON'T. They couldn't care less about it. Does it "records in 1080p"? That's what matters, even if it looks pixelated like a 512x288 video due to bad compression.

Now, the question.

Something as difficult as that can be done by the community, then? Is there a precedent around here, so I can take a look?
[Nexus 4 General] Pragmata:
QFT.

How does streaming video compare to 100% brightness? If I want to have my phone on 100% brightness would I see times around what these video streaming results are showing? I don't watch video on my phone cause it makes my eyes bleed, but I would like to enjoy the full 100% of this beautiful display.
[Nexus 4 General] DeathmonkeyGTX:
He is correct. There are loads of ebay batteries with misleading stated capacities. Lithium Ion and lithium polymer batteries haven't changed much (not counting lab samples and other crap that isn't mass produced in China) since they were invented and if the battery says it has appreciably more capacity in the same physical volume of the battery then it's a boldface lie. I wish everyone had a great high school chemistry like mine :(
[Nexus 4 General] waterface:
Only concern is, could they NOT WANT to optimize it? Leave a few weak points on purpose.

Although 22fps is just plain ridiculous. It's a thing with Nexuses though.. Nexus S, no 720p videos; GNex, crappy camera altogether (1080p, but 22fps videos)...
[Nexus 4 General] Frunobulax:
They "manage" to think the frame rate is not an issue. It is secondary to "more megapixels".

I'd easily have only 720p if it could get 60fps than 1080@"true"30fps.
[Nexus 4 General] leventccc:
Check these stats:

Stat 1

Stat 2

Stat 3

Stat 4

All of them are from galaxy nexus forum and I'm sure if you will search you can find good batteries like these. As you can see even galaxy nexus can get +5h of screen on time with proper kernel and rom. Also developer support for nexus devices are much much better than other non-nexus devices. Maybe device can come with a bad stock rom or kernel but I'm %100 sure developers can make it much much better.

As some of you can remember when nexus s was released with same specs as galaxy s they had different battery lifes at beginning but now they are almost same.

Stat 1

Stat 2

I know both of them 2h 14 min and I didn't arranged that :) It's just a coincidence.

So we can expect almost same battery with optimus g in the future :)
[Nexus 4 General] Cusa:
I get 5+ hours of screen time with my Atrix and that is on CM7 and I know the screen time will be like 6+ on the N4 with developers tweaking the kernel and whatnot.
[Nexus 4 General] raze599:
Umm....Apple Maps....
[Nexus 4 General] haloimplant:
60% of the battery life of the optimus g is very weak sauce if it doesn't get fixed, period, and your crazy sarcastic rant doesn't change that.

If these performance and battery issues aren't fixed for the release I am worried for Google and the sanity of some people here.
[Nexus 4 General] thenext1:
Even my omap 4430-powered crappy ATRIX 2 records full HD 1080p at better than 22 fps. S4 Pro should do a full 1440p 30fps real-time encoding.

Theory apart, we should be happy if it does 1080p without stuttering... you can't tell 24 and 30 fps apart so easily.

Yes, they can do it. Actually, it's qualcomm doing all the hard work developing the drivers. LG/google need just configure them correctly for the phone. And they better care about or else it'll get bad reviews all over the web (as is already happening)
[Nexus 4 General] soulaiman:
Look guys, don't blame nor the review sites, LG, Google or Qualcomm. Some of you folks are already saying they won't buy the phone but it isn't even released. Just wait on what I call Official after release reviews to know for sure what is going on with this weird problem some got. obviously this is something to do with the kernel not being optimized like it should. I mean it works but Google is perfectionizing it right now.

Also the N4 doesn't seem to have any different or slower chips inside it. It is just the software and kernel that aren't up to date on some of the review units because clearly not every device shows these symptoms.

Also the N4 features a battery rated max 2100 mAh @3.8V. To be precise it is the LG BL-T5 li-polymer battery. it is rated at a minimum capacity of 2030 mAh @7.7Wh. at its max capacity it is rated up to 9.0Wh.

If you want to know more, the device is easy to open with two torn screws and then popping some plastic things. It looks VERY well build inside with protection and cooling everywhere on the PCB. Just look at this image:
[Nexus 4 General] Frunobulax:
Actually it's pretty easy to differ 24 from 30 if you pay minimal attention. It makes a lot of difference, since we, cell camera users, don't have "video camera stuff" like motion blur and a shallow depth-of-field. So the only way videos can look less crappy is with stable, high enough (at least 30) fps.

I am yet to see an example of such improvement happening...

Is Qualcomm really the responsible for this specific task? Isn't it the Sony camera module/driver itself that lacks proper configuration? Again, if this work gets passed down to Google or (specially) LG, I highly doubt it'll happen.

I have checked out all reviews. Only two of them clearly stated "stuttering", and only Engadget told what was the frame rate they were getting. Most of the other reviews don't have a specific video recording test, much less comment about that performance.

What matters to many is just a "1080p recording" in the paper - "secondary" stuff like frame rate is usually kept aside. Unfortunately, it's looking to be the case here.
[Nexus 4 General] chrisjcks:
Actually, didn't Google already announce 1080p at 30fps?

So, if its currently not in pre-release, I'm sure it will when released.
[Nexus 4 General] abe in space:
So I've just thought of something that could account for both the Verge praising the battery life, and Engadget panning it that doesn't include a crazy conspiracy theory.

What if the video just wasn't running in hardware? What if that's one of the current missing pieces? Wouldn't 5.5 hours be about reasonable for a software-decoded h.264/similar video?
[Nexus 4 General] draugaz:
To me it looks like a camera sensor operating in the incorrect mode or in other words: an unfinished software.

According to this http://xdaforums.com/showthread.php?t=1964850

it uses an Sony ExmorR IMX111PQ camera sensor.

Which is capable of delivering 8.17MP/22.5fps stream if you use it in "photo" mode.

http://www.sony.net/Products/SC-HP/cx_news/vol65/pdf/imx081_091_111pq.pdf

Which accidently is the frame rate we are reading about, just with 4 times bigger resolution.

So if you take that photo stream and downsample in CPU/software (because your proper camera sensor drivers are not ready yet), you will get said result.

Sensor itself is perfectly capable of outputting 1080p/30fps or 720p/60fps. To do that you need to put it in video mode where it does internal downsampling of 8mpx to 1080p (closer to 2mpx).

I don't know, maybe it is just unfinished. Like "oh ****, there is a bug in LG/Sony driver somewehere, let us just use photo mode for the time being". Or google thought they could do better video postprocessing if they get full 8mpx resolution and downsample it themselves (some geek finally found something to make those 4 cores actually useful :) ).
[Nexus 4 General] Frunobulax:
Funny you posted from your HOX - I have one too (it's in maintenance though).

HTC also announced it as having recording @ 30fps. I think you know as much as me that... just isn't true.

_____

I feel in a peaceful, perfect world around here. There's a lot of conviction that a software miracle will happen, and I'd really think it would be nice if it became true.
[Nexus 4 General] raze599:
The FPS of a video recording also heavily depends on the light levels. On my Desire HD and on the old Samsung phone I had, video FPS was good outside in bright sunlight, but use it in a slightly darker room and it just drops.
[Nexus 4 General] haydonxda:
That photo scares the heck out of me. A ton of press contact RF connectors? I remember that garbage from when Samsung thought that would work for GPS antenna on the Captivate. I can't imagine what will happen when they use that for the rest of the antennas.

I've just decided I'm sticking with the Galaxy Nexus for at least six months until reliability reviews are in.
[Nexus 4 General] Rusty!:
Phones have used them for a while, HTC especially.
[Nexus 4 General] draugaz:
Worry not, your Galaxy Nexus has a bunch of such contacts too.
[Nexus 4 General] haydonxda:
Well okay then. Just looked at the GN teardown and see a few. Not as many as this. I'll still wait a while though. :)
[Nexus 4 General] PhilipL:
Hi

....Which causes Wi-Fi antenna issues on the HTC One X :eek: In the case of the HTC One X the problem seems to be the polycarbonate back can be compressed easily, pushing against the pins depressing them, because the pins are bent bits of metal rather than true springs, after several compressions they become permanently depressed and so no longer make good contact.

The Nexus though shouldn't have this issue as the back isn't going to depress anywhere like the HTC One X moulded back, for a start it has the glass on the back to stiffen it and is a different design.

These types of connections are used quite often, and generally they cause no problems, although I wouldn't want to be taking the back on and off all the time as they will wear very easily. Probably another reason for having no removable batteries as it allows such a design to be used.

Regards

Phil
[Nexus 4 General] Rusty!:
Indeed, my phone suffered that problem and was fixed under warranty.

Still, that's more of a design flaw on HTC's part rather than a problem with spring contracts in general.
