For all the speculation/rumour/claims that the i9500 would be more efficient than the i9505, I can't find any reports supporting or disproving this now that they're both out there.
Has anyone had the opportunity to side-by-side test battery life on both versions of the S4? (regardless of what AndreiLux says about the premature firmware).
I'm very interested in this information as well with the current setup of the devices.
I'm about to buy a i9500 due to the claimed better battery life over the i9505 as I don't care about LTE, but I have been unable to find out any information about if its actually better.
If the battery life is about the same, then I would get the version with LTE in case I decide in the future to switch networks and use it.
Anyone got any links to a review on battery life between the 2 models?
they have the same screen so they also therefore have ROUGHLY the same screen on time. standby time will be spectacular on both due to the 2600mah battery.
both seem really good though
There was a marginal difference in my tests...
Started from a factory reset
Both devices on 100% (recd the fully charged msg)
Did the same benchmarks on both for about 40 mins (edited to much less in the video)
By the end of the video the Quad (I9505) was about 1% lower (87% compared to 88% on the Octa)
Isn't really the best of tests but would give you a picture
The recording quality in the sound recorder on both devices is also very different... check the video to hear samples

LTE eats more battery period.

Thanks for that Ashwin - 1% means a lot of fuss over little difference! The sound quality seems more natural on the i9505, and louder/hollower on the i9500.

Yes, regardless of what that thread says, I wanted to know what people are seeing in actual usage, with firmware/chipset/ROM/etc in their current state.
http://www.gsmarena.com/samsung_galaxy_s4_i9500_vs_i9505-review-930p3.php
Looks like the i9505 is quite a lot better with the battery currently. Plus wouldn't you rather take the chipset that is better with sharing source code for drivers for custom roms

Are there any comparisons of the two cpus available on the s4 when it comes to battery life? Thats the only reason for me to try to get an exynos version if its shows to be better in that respect.
Yeah, that's a good question I want to know the answer too, there are many people having testing devices but they are too hungry about testing the damn processor and gpu instead testing properly the battery life. -_-

Lord knows battery Life is very important to me.
the guy that's testing whatever people tell him to test said that when his battery got down to 30% it lasted like 3 hours with max brightness and benchmarks running

With wich cpu? Also no comparison to the other version mentioned here.
I'm not convinced, even with S3 you can spend all the battery juice in 3 hours if you want. To do a proper test you need to leave the device doing the same job like an Snapdragon S4 during the same time.

Octa has a longer battery life than SD600.
That's why samsung used 8 cores technology.
And by the way the 5inch HD screen saves power too for both version

Thaty what one hears, yes.
However I would like some actual test reports - for instance how long does the phone last for web browsing, for video playback and on standby?
I would like to see actual numbers.
As for the screen:
It is said to use 25% less power compared to previous amoled display generations. However that 25% value is something we have to trust samsung on I think, at least I have not seen any actual tests on power consuption of the display alone and it's probably not easy to test.
The way they have managed the display to consume less power is to use use phosphorescent instead of fluorescent green diodes, which use way less power. Until now they could not produce the green ones with an acceptable lifetime. The red ones have already been phosphorescent, and the blue one are still fluorescent since they are hardest to produce.

This. This so many times over.
So many people are parroting the "Exynos will have better battery life" thing but this really remains to be seen.
If the better battery life is in exchange for crippled A7 performance at inconvenient moments then it's useless. If better battery life isn't available for when you're using intensive apps then it's also useless.
Hey guys, really, even though we try to justify it and show good performance of the battery of our new machine, the truth is that the S4 is very disappointing. The advertised battery with a very good performance and duration of up to two days, but the truth is that in reality do the same things I did with my S2 and S3, the duration is shorter. Roms developers have struggled to reduce consumption, but remain excessive and reheated, not because of them but this time Samsung blew it with the battery, as it did at the time with the first version of the Galaxy S. was a great revolutionary cell, but the battery was not the same level.
What to do about this? complain all, writing in the forums, on the website of Samsung, on Twitter and on all networks require Samsung to correct and improve performance or improve and launch a new battery. Or will we wait for the release and change of cell and paid so much for him to only have four hours of screen use? I leave it to your consideration.
forgive the long and the English with a translator, but it's crazy not to use it how and when I want x fear of running out of battery.

well before you complain, test first.. I have an S3, I ha a note 2, and now S4.. I can safely say the battery longevity with my usage is in between S3 and Note 2... so it is actually good... bearing in mind I only had the S4 for 2 days and the battery hasn't reached its full potential.
On my old S2 I was able to get about 2 hours of screen use. S4 give me roughly 4-5 hours, so yes dear OP very disappointing. Maybe two weeks of constant use would make You satisfied? I think that it can be easily achieved by Samsung - by using car battery.
Hi guys.
I'm making a decision between this and the Samsung galaxy tab s 10.5 .
It seems that the battery life on the sony is actually much better than the samsung despite the samsung having a greater capacity. Could somebody please post up some stats from the real world usage of the sony? I'm thinking total screen on time, total battery life, time between charges.
Thanks!

I will not have less than 5% battery till 2 days or so. But I can tell you for now that watching movies, a full charge last 11 hours.

Look in the tweak for more battery time thread a few down from this one. I posted mine in detail.
Considering the capacity of the battery, the battery life is outstanding. For example when the tablet is idle it uses virtually no battery, games and movies will see it drop but not at a fast rate, it would defo see you through a day of hard labour. This is why sony stuck with the quad core, and the very beautiful screen. Having looked at the samsung galaxy s with their superior resolution and octa core, Im glad I went with sony, as looking at the threads over on xda people are not happy with battery life, and they are complaining about lag in games, I guess the octa core era has not been totally settled
Hell. 4 cores is more than you need really! Especially in Android. It's not even really used fully in a much more complex os like windows!
BS. 4 cores is saying nothing about the capability of a device.
There are plenty of laggy, slow phones and tablets with 4 cores out there.
I think that the number of cores is less important than the actual day-to-day handling of a device.
I am trying to make a decision between the two best devices here, and the Samsung has double the number of cores. This is irrelvent if software and hardware implementation means a slower actual experience than a device with half the processor cores.
Or indeed a longer-lasting device with a ~30% smaller battery capacity.
I've seen the battery thread mentioned in the reply above- thanks for that.
Can anyone else post their screen-on time or general impressions of battery duration?
Thanks

My point wasn't that because a device has 4 cores it must be good. I have two Rockchip 4 core devices that are not fast! My point was that octa core is complete overkill as even with 4 cores they are barely ever all used.
On an additional note: I know that the point of the Samsung octa cores is that they can run on the lower freq cores for low Intensity processes for improved battery life, but our 2.3ghz cores can also run at a lower speed when more is not needed and although this may be slightly less efficient than the Samsung 1.3ghz cores, I would still choose the Sony any day on cpu alone!
Duplicate post. Please ignore/delete.
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.
Hey guys
I have a brand new GS5 and the batterylife is nowhere close to what reviews say. Yes I get 20+ hours but that is only counting in all the hours I am asleep.
When taking it off the charger and just browsing the web on autobrightness inside in just under a hour the battery is at 79 percent while on wifi...
Also Android system is what consumes the most. How can I fix this ? I don't want to root it yet but if I must do that that's fine for me.
Also while sleeping the battery loses 12 percent in just 6 hours. This can't be right ?

bear in mind battery technology hasnt advanced quite as far as screens and connectivity has. we have bigger screens and constant connected wifi and apps.
you're not going to get all the battery life you want. under mdium use id say this phone is about 12 hours use
Yes I know that buy it is worse than my s4 and even moto g. It can't be right. I've owned the one M8 and it should more or less like that phone but it is not by FAR. I wish I didn't break my z2, that phone couldn't be sucked dry in one day.
All this aside : if Android kernel and system is using the most energy something must be wrong

ok let me ask you this then instead
how much battery life do you want from a device that has a 1080p screen, wifi, 4g and a cpu thats higher than a P4 desktop?

Let me say you this: that's not the point. Don't try to defend samsung because you like them.
To the point: this is one of their flagship devices and I know that normally it should last a lot longer than it does now. And to answer your question it should last almost as long as the one M8 wich has near identical hardware but a less big battery.
My xperia z2 with the same chip but an even bigger display that is brighter lasted at least 22 hours with 7 hours screen on time. Yes it had a 400mAh bigger battery but that doesn't mean that there should be such a big differencr in things like browsing the web. A 1 to 1,5 hour difference yes maybe. That being said I clearly have problems with my battery draining while I'm asleep.
I have owned two s801 devices and I know it is a really power effecient chip so it is not normal that I lose 30 percent after 1 hour on really low brightness. The fact that android system and kernel is at the top of the power consumption chart is also an inidcation that there is something wrong with the firmware. I tought someone could help me that has had the same problem by suggesting for example debloating the rom, installing a certain kernel, disabling a certain samsung app and so on.
So if you have nothing better so say please may I ask you to not respond so that this thread can be maybe somewhat usefull to other users
Root, takes of all. Touchwiz craps and change a kernel you get more battery life.
