Yeah what the question title says ..
Also I would like to know for everyone that has a Nexus 4, how long does your battery last when using it constantly with brightness on & off, without battery savers or anything, just the average of how long your battery last
Definitely S3. When I bought S3 I had about 2 days activity and about of 5-6h screen. In N4 I also have 2 days activity, but about 4h of screen. Same using.
I have my N4 with franco's, greenify and lux. Around 3-4hs of SOT.
I would say my Nexus 4 lasts longer than the S3. I had the S3 for about 2 months and I didn't like it. I get one hour less on screen time than on my Nexus 4.

S3 imho
It's pretty subjective when you consider two things.
S3 has a removable battery and can be extended with something like a 7000mAh one, the N4 does not
S3 has a dual-core 1.5ghz Krait processor vs Nexus 4's quad-core 1.5ghz processor which will consume more power*
*(S3 is dual core for north american and Japanese models, I9300/International is quad core 1.4ghz A9, the international version has 1GB ram versus the 2GB in the other models)
Just looking at that comparison, especially to the US/Jpn model of the S3, you can pretty much assume the S3 is going to be capable of running longer on battery. Just not sure why they didn't put 2GB ram on their quad-core phone, the combination of both would have been nicer, but there's so many variants of the S3 it's probably why Samsung doesn't even list processor specs on their site officially.

What do you mean by "Screen" ? Screen time? Cause I'm talking about constantly using it
I feel like they're roughly the same. Probably give or take 30 minutes screen on time

Hi,
Had it a week now, and the battery life is awful compared to my prior Note 2. The old phone could get through the day, no problems, but this one is flat by 6pm.
I suspect its to do with the Knox process using 10% of the processor (according to usage timelines pro), even though ive not got Knox enabled.
Also it seems to struggle to reconnect to the 3g network (three UK) after losing signal. I have to put it into airplane mode, and off again for it to re-connect to the network.
Hoping both these can be fixed with a software update, but has anyone else found these issues, especially people coming from a note 2
thanks
George
On a poor signal mine is the same, my note 2 has a signal, when my note 3 doesn't. Also battery seems better on my note 2, on day 5 will see how a few more cycles of charge pan out.

I blame Exynos. The US and JPN versions will be much better.
Just turn off all the useless gimmicks such as air gesture and smart xx features and give it a few days before judging. I'm on fifth day with the phone and its temperature and battery life is better than it was on first day.
To give you an idea, that's my battery usage for today and I'm still at 43%. Didn't even start at 100% but 92%. Though I've been on wifi all day with good signal, not on data connection, so that helped with low battery consumption.

Samsung has the worst antennas anyway. where i am living i had 0 to 1 bar at my note 2. with note 3 it improved a little bit. it displays the same amount of bars but at least i can make phone calls with no problems.
At the same area i testet the new Xperia z1 and it has almost all the time 3 and more bars...what the hell samsung...not everybody is living in an signal oversaturated city....
After 5 days, battery life is impressive and improving (i think)

San Francisco doesn't have a saturation of signal?
Same thing again and again.
Buy a top notch mobile and turn off all features that make it top of the line to make the battery last one day.
Really poor battery life on mine.
Sent from my SM-N9005 using xda app-developers app
I think it's a cell handover problem
I'm not sure the antenna itself is weak...I've pulled over 10 megs on 3g in a two bar situation. However it seems over keen to switch cells . I have a tool that logs which cell you are on and even when I'm stationary it keeps swapping cells
Also the number of bars on different brands cannot be meaningfully compared since some companies stretch the truth about signal strength by not having a linear scale *cough apple
Looks like the poor handover was the sim card... went into three store and they said it probably was .
I was very sceptical since it worked fine on my note 2 but it does seem to have fixed it

Mines got better too
tbh its got better after a week of cycling.
Its still annoying as anything that knox is munching 7-15% of cpu power constantly and I dont even use it ... however its not as bad as it seems, since it seems its the CPU idling at 300MHz so in fact its less than a 3rd of the apparent figure...

You may try to
- turn Google Now! off entirely, voice search and answers still work just not the cards or some app controls (but there's S-voice for that)
- switch searching for wifi networks off
- I do not recommend turning wifi off during deep sleep, it causes more wakes and drainage on my Nex4
- use the S alternatives of as many Google apps as possible
- look around Maps to see if some sort of location sharing is ticked in, allow the only apps to access location data that you really need
- look around Know security, maybe it is part of the drainage
- optionally: try out AppOps to manage individual permissons per apps, I don't know if this works with the Note 3 though
Hey guys I just got a Nexus 4 with a cracked screen for $50, I just fixed it also.
I love the phone, I cut my AT&T sim to fit it.
I've just got a few general questions though:
If I disable two CPU cores, will it still be a snappy phone? Kinda like the S3? I mean the S3 has two cores right, not 4. Would it improve the battery life a lot more?
In the battery mod thread I've seen, I asked if anyone has the 3D model for the backside of the phone(to add another battery). I was wondering if anyone has some info on this? I would gladly risk this phone for an extended battery
What app could I use to disable two cores? Is there a kernel for 4.3(jss) that does this?
Thanks,

As far as I know, it's only using all the cores when neccessary, so if you're worried about battery life just reduce the number of apps you use. I'm using the Purity rom now and easily get a day out of the battery.
As counter-intuitive as it sounds running more cores in a multicore CPU is more power efficient than running a few cores in most modern multitasking systems. You're spreading the process load over multiple processors that can be run at a lower clock speed than a smaller number of cores running harder.
Well drooling over the Ok Google feature of the moto(always listening).
Is it possible to make a kernel that would have 3cores running max, and 1 core running 196mhz?
Then make an app that's using that one downlocked core to always listen. I wonder what our battery life would be though
What is the typical battery life / performance for Galaxy Note 4 users on this board? And what is the typical life advertised by Samsung, and featured in reviews?
I get about 13-15 hours, with 3 hours screentime on my Korean Note 4 (sm-n910k). But I thought I'd seen reviews boasting near two day usage...six-ten hours screentime.
What is going on then for me? I am BITTERLY disappointed with battery performance: The attached screenshot shows my typical day. Is this normal for you too?
In this screenshot example no calls made during the day, no GPS usage, and almost no apps beyond Gmail and Twitter. I have just a handful of additional apps installed, but the phone does however appear loaded with bloatware.
I took the device to Samsung Service Center in Seoul on the weekend (for a second time) and showed them the problem. It drained 5% from 15 mins of screentime right in front of the engineer.
After resets and reboots engineer said this was normal and that all tests showed the phone to be normal.
Or is it only normal for the Korean variant, but NOT for the international variant?
Help much appreciated!
Mine from Korea too 910L
And I haven't use 3g that day, only play some heavy graphic game 45 minutes and use wifi
Sent from my SM-N910L using XDA Free mobile app
I got both the SM-N910K an the SM-N910C at home, mostly because at first my 910K did not want to enable 4G in my country no matter what (even though it was supposed to be supported) So when we got the local 910c i got one too. It turned out that after a firmware update, my 910K started working in LTE in Brazil normally, i dont know why. But what shocked me was the terrible battery life of the K in comparison to the C. SO i swapped their batteries to see if it was a battery issue but the C kept maintaining amazing battery life. So I rooted the K, replaced the rom with a custom N910S rom that i found online (it works just fine because they are identical) and begun deleting crap that i knew was unneeded because my C didn´t have it and while i am still running some tests it would seem that the battery life of the K has been improving. There are a ton of bundled crap inside the firmware, even the custom one...so hang on to your K, once a decent custom rom comes out of it, it will be a lot better. Mind you, i also compared them a bit and the screen on the K seems better than the C when it comes to color fidelity (the C is a bit warmer), and going thru benchmarks, the K always pulls ahead by a bit. It´s almost as if it was clocked a wee bit higher. Keep digging!
N910H with N910C SweetRom v2
12-15hrs autonomy, 5h30 to 6h of screen on time. 50% WiFi, 50% HSPA+.
Disappointed a bit because I expected an improvement over Note 3 and it's not the case at all.
OP, something is wrong there try a factory reset or a custom ROM. Root and install a wakelock detector to figure out what's happening
Thanks for the feedback. What are others getting in terms of time?
Especially interested in non korean models.
Hello everyone .
I am currently a Note 2 owner and I skipped upgrading to note 3 as it did not seem such a big upgrade to me plus all the goods <software> was brought to me by the devs of the Eteam . Was willing to upgrade to Note 4 but then Edge came along and now thinking of getting one of these frontier devices.
The problem that I see from the forum is the battery life in this device , I can consider myself a power user and I do get in average of 4 to 5 hours of screen time on the 2 year old Note 2, anyone coming from Note 2 can shed some light regarding this issue as I am so used to have more than just 4 hours of screen time and that is a compromise I am not willing to make since I consider this am upgrade , is Edge worth or better get a Note 4 ?
Thank you in advance.

Here's the thing, note edge/note 4 has double the screen resolution as your note 2, and the edge has a battery 100mah less than the n2. Granted the processor can give you plenty of standby time, but screen on time won't be as good as you currently have it. You can always carry a spare battery, since it's a Samsung.

I thought the new screens are more power efficient <25 %> compare to the 2 year old tech on the Note 2.
So with a Note 4 would be also the same issue you say ?
Sent from my SM-N910C using Tapatalk 2
I had the Note 2 and it was not exactly a stellar performer in SOT from what I recall. You won't notice much difference going to the Note4 or Edge in that regard. Maybe a slight improvement. But the screen quality and performance will more than make up for it. Plus the new fast-charging capabilities are pretty effective.

You can get the Ultra power saver mode too in custom roms but I am asking in identical conditions, which of the 2 has longer screen time , it makes no sense to me to use a 1000 usd device in black and white just bcs of the battery .

You can't compare the note 2 and note 4 or Edge as apples to apples. The processor alone on the Note 4 is more efficient. And if you get the T-Mobile variant you'll get root and can do greater control of things that eat battery.
But even the stock versions allow you to at least disable most of the bloat or apps you won't use thereby stretching the battery life out.
I have both the note 4 and note edge and get at least a full day on them. I consider myself an average user doing primarily email, music, web and some gaming (temple run 2 is my addiction) and I get at least 4 hours of screen time with about 25-30% battery left by the time I go to bed.
I picked up the Edge after having a Note 2 from release. I see a massive battery life difference for the better. I had replaced the battery in my Note 2 twice, and in it's prime with Ditto Note flashed, I was pulling almost a full day if not a full day of heavy use. Since picking up the note, I've been getting home from work with atleast 30% left. Actually, I don't think I've had a low battery notification since I picked it up. Looking forward to rooting, but out of the box...I'm impressed Samsung.
OMG N2 to N-edge
YOU WILL LOVE IT, I cant put it down. The phone drinks battery but purchased 2 extra batteries with portable charger. When you buy the phone samsung gives you 50% off all accessories. Well worth it, I loved the N2 and the N3 wasn't enough to upgrade off contract. N-Edge AWESOME:laugh::laugh::laugh::silly::silly::silly::victory::victory::victory:
And as an added bonus, the edge has 'adaptive charging' which allows you to go from 0%-50% in 30 minutes. That combined with 'quick charge 2.0' and swappable batteries, you should be good to go.

This was SOT of my Note 2 when battery was new.
More than 9 hours on one charge.
When I hear you guys telling that I need to carry a spare battery with me or that the supercharger does 50 % in 30 min , I simply get scared.
Of course I will root and debloat the device but .............
Still sitting on a fence about getting this awesome device or not.
Thank you all for the feedback.
Maybe someone will come out with an extended battery that will last all day? At least I hope they do.

Same situation. Same comments. I'm on the att varient. I heavily modified my note 2 and frankly I'm OK with no root for now. Very happy with my upgrade.
I switch from a Note II to the Note Edge a few days ago and I love it! The only thing I'm missing is root... Ordered the spare battery charging kit just like with the Note II using the 50% off coupon. do iT!
I'm in the same boat.... but want an exynos version. ...

You'll receive a 50% off coupon code once you register your device with Samsung. It's a one-time use only... Hope that helps!
My Note 3 has about 15% better battery stats than my Note 2. The Note 4 from what I can tell is about the same as my 3 but that's with the higher res screen. My guess is that the Edge will be about the same as the 2, at least that's what I'm expecting anyway.
Now only those with an edge could attest to this but if you use your edge screen wisely to skip all the full screen on 10 sec checks of whatever wouldn't that save bat in the long run. If you can quickly edge through your notification without turning the whole thing on that should save you lots by the end of the day.
