For me QHD displays are too much for a 5.7 inch phone. The exynos version looks pretty powerful, but I guess I`d rather have better performance than insane ppi.
Watching some on/off screen GPU benchmark reviews for the LG G3, Oppo Find 7 and S5 "Premium", the off screen (1080p) tests had an average of 51% higher scores than on screen (QHD) scores. I mean, WOW! That`s a lot! I can post the results here if you want to skip the trouble looking for it.
One guy on youtube changed his LG G3 resolution from QHD to Full HD using NOMone Resolution Changer and used Xposed to change DPI and font scale of native apps to make them work.
What do you think about this? This could possibly increase overall performance+battery life and definitely increase gaming performance.
The videos about resolution downscale on the G3:

Sounds like you need to stay with your note 3
... and reduce resolution to 720p
and, no one cares about benchmarks..
and... lol reading above comments make me laugh
why you bought note 4 if you want to reduce it's resolution, there will be 1080p device later if you want SD805
Daaaaaamn, this a deal breaker... If I cannot reduce the resolution of the Note 4 to 4:3 CRT TV 480i letterbox... I will not buy it, what a piece of crap! I was hoping to get at least 6 months of battery life on each charge with CRT resolution... I reduced to 320i my note 3 and it lasts almost a year on a single charge. The only problem is that I am having issues watching YouTube in HD for some unknown reason.
funny stuff!
we ***** and moan that we want QHD/4K/ultra definition on our "5 inch video screens", then once we get it, we complain that it uses too much battery life, so we have to "downrez" it..
you just cant make some people happy...
I'm more curious of how the screen will look like if in 1080p, especially the pentile effect. We know that we still see the pentile effect somewhat on Note 3, not sure on Note 4's 1440p screen.
Don't really care about performance.
I can't see any difference, but I can't see any pentile on 1080p phones too so...

if you reduce resolution to 256 x 144 battery life will be improved by a factor of 10!
much better than 1080p! OMG!
Is there any sound reason for bashing the OP ?
Just because he thinks a little bit different than you, maybe a step ahead of you ?
His idea is no nonsense.
If it IS possible to boost perfomance by lowering the resolution to e. g. Full HD, that would be quite beneficial.
Practical example: Let's talk about a game, "World of Tanks - Blitz".
Great game on the PC, not so great game on Android. Reason: Graphics are not the best. At present, there's a kind of universal version out, all reduced graphics to make sure the game works with most Android devices, even the weaker ones. Game publisher said they're working on a version you can adapt to the performance of your system. Hope they won't lie.
2560 x 1440 pixels is quite a number.
Rendering that many pixels WILL take a lot of processing power, WILL be quite a burden on the CPU and the battery.
So the results are likely to be: Great graphics but bad performance - or bad graphics because the game recognizes the overall performance as being too low for high details AND fluid gameplay.
Plus: You can watch your battery going down in no time, as rendering that mass of pixels will take a lot of power.
Let's say we've got a resolution of 853 x 480. SOUNDS like subzero quality, but don't forget the tiny screen (compared with a large PC monitor).
If it's possible to display 853 x 480 using the highest details setting, the result will look classes better than 2560 x 1440 with low details. You won't be able to spot single pixels, just a wealth of fine graphics.
So a reduced resolution and highest details will look MUCH better than highest resolution and low details. That's benefit one.
Second, gameplay will be vastly improved by a higher framerate and more CPU power for handling all the netcode and stuff.
Third, our battery will last far longer because of the lower battery drain.
Result would be a great looking, blazing fast game which won't suck your battery dry in no time,
And that's a reason to laugh at the OP, for bashing him ?
I do NOT know if reducing the resolution AND saving ressources is possible.
But IF it's possible, it would be a great step forward.
You will NOT able to see the difference between full resolution and reduced resolution on the tiny Note 4's display.
Only differences will be graphics and details quality - and higher speed, better framerates, more fluid gameplay.
And there will be always some room for compromises like slightly higher resolution and the like.
Now bash on if you still feel like.
Just a bunch of trolls. There are many people dowscaling resolution to play. I personally leave at 1080p all the time. Just restart and everything rescales to the right dpi.

I don't know of a way to reduce it to 1080p, but wouldn't it make more sense to buy an s5? Battery life was superb on my s5, still wouldn't swap it for my note 4 though, optimise your note 4, it holds its own in terms of battery life and performance.
All depends on why you got a note4, I love the s-pen, I like the added fingerprint reader and heart rate monitor, and like the better camera with OIS. I already can't see the pixels on my Note3 though, so why would I care if I downgraded my Note4 to "only" that same resolution? Having longer battery life and higher performance for all the bits that matter to you sounds like a much better plan than having more pixels than you can possibly see.

You didn't get the idea at all. It's about making games run faster and with far better details. Same as with PC games.
Read my post!
Edit: It was me not reading the post correctly. Sorry !
I'd be interested in this also. I would love the ability to lower the resolution for a few apps I use on my note 4
I like this idea for performance in games and battery saving but you definitely can see the pixels on the Note3 and indeed any 1080p mobile right now. The extra resolution on the Note 4 really pays off for normal useage but games should be able to default to 1080p at the very least.
Phones should have a resolution change option like pc's these days anyway.

Sorry, I think you misunderstood. I was agreeing with you. My point was that I don't really "lose" anything if I downgrade the resolution as on a screen this size I can't see individual pixels even at 1080 I was also countering those who said the OP should have stuck with a note 3 by saying that the note 4 has many other improvements as well, and that the resolution, though better on paper doesn't really matter.

Yes, I indeed did - I did not read carefully enough.
Just added a comment to my post regarding this.
Thank you for pointing this out !
NOMone resolution changer in the app store lets you bring it down to 1080P.
Has anyone tryed this?
I´ve seen people modifying the regular sized GS6 EDGE build prop to change the resolution to 1080p and the dpi to 480
They get an amazing performance improvement and a nice bump in battery life
Has/Can anyone try this?
I will test this with my GS6 EDGE + as soon as it arrives but i wanna know if i can scale it down to 1080p since 1440p is a bit overkill for me
How is that even possible?
Its not really, all that happens is that everything is rendered at 1080P and the GPU then has to upscale everything to 1440P to fit the fixed resolution of the screen.
People make grand claims for performance and battery improvements but really little changes and sometimes its worse.

I cant see how modifying the build prop would not only upscale the camera to true 1080p but also improve battery life?
Surely the more the camera is used the more it will burn through the battery?
If your going to get it working I would love to see some screenshots of performance benchmarks and whatnot.
Hi all,
I personally don't think there's much difference between 2.5K and 1080p on a ~5 inch display. Has anyone with root found a way to and tried down scaling the display output to 1080p?
If so do you notice any visible difference and has it noticeably improved battery life?
I'm not convinced how much difference it would make as the display itself would still be physically outputting 2.5K pixels but at least the processing side of things would only need to push 1080p.
Thanks!

I searched for an answer to the same question. I doubt it's have much impact on battery life honestly. The gpu isn't working as hard, but that's not the biggest drain by far. The best reason to do this would be improved performance in gpu-intensive activities like gaming. However with this phone that hardly seems necessary.
(I suppose, theoretically, you might get better battery life during gaming)
1080p won't look nice on this screeeen

My guess is the won't matter because the GPU will need to work just as hard. The number of pixels you push to the screen will always need to be converted to the number of pixels the screen is designed for. Pixels are more hardware related than software related.
A screen has several tiny LED's that illuminate to display the image on the screen. The 6p resolution is 2560x1440 which equates to roughly 3.7 million pixels. It has to display 3.7 million pixels. 1080 equates 2.1 million pixels but the 6p has to display 3.7 even if you only push 2.1 million pixels to it.
Depending on how well the Android OS is designed it wouldn't be out of the realm of reason to say that dropping the resolution to 1080 might reduce battery life instead of save it depending on how well the code is reused internally and where the interpretation of scaling happens in the chain.
I talk out my ass a lot so I am only guessing that the above is true.
Downscaling to 1080p won't do much for battery , the pixels still need to be lit, but the GPU will be less stressed, it doesn't have to render those extra pixels with new information, its just upscales

That's my understanding as well. It's still rendering at lower resolution, which requires less from the gpu, but then upscales to the native resolution. I'd still suspect this will improve battery while gaming, but not in general use. Entirely direction though.
It won´t look good on the screen, that´s for sure. Downscaling might only be needed if you want to play a heavy game which wouldn´t run fluid enough on the Nexus 6P, due to hardware limitations.
Samsung is advertising S8 and S8+ 2960 x 1440p the device defaults to Full HD+ and can be changed to Quad HD+ (WQHD+) in the settings. My concerns are why? Battery life? Better bragging rights concerning performance? I am going to play with one today and will report back on if it makes a difference switching but I wonder if reported battery life from Samsung is going off of Full HD or the full pixel count. It sucks to even have to question this.
Yup I've been posted about this for a few days now. They are being incredibly misleading and they are doing it on purpose to disguise the **** battery life. The Samsung battery life is using FHD I am pretty sure because on their spec sheet they say that the "default" resolution is FHD, which will then be what their rated battery life stats are based on. Of course they then have people comparing the S7 stats vs the S8 but the S7 ones were based on it running its native 1440p resolution because at the time of release, the ability to change resolutions did not exist, it came in Nougat. So effectively Samsung are being extremely sly. You have battery life stated on the S8 which is basically the same as the S7, and what they obviously don't want people to figure out is that the S7's was 1440p and the S8's was 1080.
How much difference that makes will be interesting. It will obviously make less difference on browsing and light use (but might still but noticaeble) and a lot more difference on video and games.
Of course the other issue is they keep touting how good this 1440p display is in all the advertising......but it doesn't run at 1440p by default does it? Noooooo, because the battery is ****!
Why use max hd it's only any use in vr
It uses FHD resolution by default
The Galaxy S8 and S8+ have QHD+ screens like its predecessors. Unlike its predecessors, however, Samsung is tuning down the screen resolution to 1080p by default. This is for power efficiency purposes, as it decreases the number of pixels that need you be rendered. This is the same optimization that Sony used on the Xperia Z5 Premium, but that had a 4K screen.
Of course, when the content calls for it, the Galaxy S8 switches to its native QHD resolution. And you can always set it to use QHD all the time. It’s just something you have to keep in mind if the user interface looks a tad too big for your eyes.

I took a few pics and very closely eye balled the settings while going through them. I have a true dedicated theater room I spared no expense on and literally a HUGE freak when it comes to imperfections with any display. Options are HD+ 1480 x 720, FHD+ 2220 x 1080 (out of the box) and WQHD+ 2960 x 1440 and you can tell a difference but it didn't bother me. Obviously the higher resolution is sharp and starts to fall off from there. In a blind test you would be able to notice at regular viewing distance imo however its not at all distracting and my guess is no one will ever question the beauty of the screen at even 720 to hunt down settings outside of people like us. Having said that, when I locked the demo unit it reverted back to WQHD+ so I compared at the screen resolution option right there.

It's not opinion its fact. If they weren't trying to make it look better than it is, they would provide a like for like comparison with the S7 instead of conveniently showing battery life stats that are almost the same as the S7........and leaving out the key detail that they are completely different resolutions and not comparable at all. It was pretty clear something was up during the reveal event when they VERY quickly flashed up the mah of each battery and then quickly skipped past it without mentioning the battery life at all.
I still don't see what relevance an article by slashgear has to do with anything. It's an article written by slashgear, barely mentions battery at all and provides no comment on the battery stats vs the S7.
Your argument is like saying its our opinion that the earth is round but not everybody believes it.....doesn't matter what they believe, it's just a fact. If they wanted to be open about it, they would have provided battery life stats for the higher resolution so that it can be directly compared to the S7, instead they provide a 1440 screen, go on about thish high resolution screen in all the advertising, then set the default resolution to 1080 and quietly provide battery stats that are based on 1080, but don't actually ever tell you that the stats are based on this, because that would make it clear it isn't a fair comparison to the same stats they provided for the s7.
Umm sorry to break it to you but the Galaxy S7 with Nougat also defaulted to the lower resolution and it made ZERO difference to battery life. There is plenty of reviews and comments about this. Though it does make a difference in some apps and games where the scaling works better at 1080 resolution as higher than that and the assets are so small they are harder to use with a touch screen. So instead of stating facts with no actual facts why don't we wait till some real reviews come out and test the battery before we jump to conclusions.

BIngo!
The one thing people seem to overlook with lowering the resolution is the positive effect it has on the processor. Samsung may very well have it set at FHD out of the box for better performance power for the general user. Obviously, they also say it very slightly improves battery life - but by all accounts - and even my own experience with my S7 - it's pretty negligible.
If you don't mind, I would love some clarification on the S7's ability to change the resolution:
First: doesn't the display draw power because it needs to produce light? Don't 2 pixels at half brightness create the same amount of light as 1 pixel at full brightness (since this is an OLED screen) or is that single pixel more power efficient because power draw isn't linear?
Second: does it physically turn off pixels or does it just change the DPI because turning off anything but 1/2 looks incredibly bad so I'm assuming it just changes the DPI. If it does just change the DPI than the power draw from the display should not change much but the GPU usage should fall.
Isn't the resolution also a function of the power savings plan settings which was new in the S7? The power savings plan also throttles the SoC and limits data speeds.
my 2 cents
When switching resolutions on my S7 Edge I haven't noticed any battery increase or decrease. So I just keep it at QHD

I think it's more about gaining performance, especially in games where you wouldn't really notice the lower resolution anyway. It's also easier on the eyes for some people in certain applications as the UI elements don't shrink so much.
It's nice to have the choice. When I swap between QHD and FHD phones the difference is negligible, certainly you can see a slight sharpness decrease if you look hard enough. Just not enough to warrant the loss in performance for many people.
There is a reason Apple haven't increased their screen resolutions yet. The need just isn't there for the average user. VR is the biggest reason for a higher res, that's something that definitely benefits from it. Again, not everybody has that need.
Personally, I like choice. I'll be switching between both depending on what I am doing.

I really disagree on most points.
First, the myth that people won't notice the difference, they will. In the near future when screens keep improving, you will notice how bad a low res screen looks so having QHD is nice in future proofing.
The UI elements can be changed by changing the DPI which Samsung did from the Note 4 to the Note 5 (Note 5's UI has smaller elements, they are both 1440p) so there are obviously people at Samsung working to make the UI visible and accessible and the resolution isn't a problem for them.
The performance hit isn't that big to be honest, it comes down to hardware and software optimization, a slight change in DPI will not make much of a difference.
And one last point, it's nice for phones to have great displays because it puts focus on display technology and increases research on those areas.

I agree, I wasn't saying that phones shouldn't have a QHD screen. I was merely suggesting that it's nice to have a choice and Samsung has provided it. There is of course a slight difference between the two but because of the smaller screens phones have, there comes a point where the resolution doesn't make a difference anymore. 1080p to 4k on a TV is nice but even that isn't a huge leap, even on my 75 Sony.
The real difference comes from other areas such as colour and HDR. QHD is pretty much the max you'll ever need unless it's for VR.
I have had many phones and there is only a small difference between QHD and FHD but it is there. I will be using QHD for browsing the Internet and photo viewing etc and I will drop to FHD for gaming. Options are a good thing.
The difference in battery use between FHD and QHD is so small it's not really noticed. The reason FHD is default is because a lot of apps look sbetter in FHD.

Is that statement backed up by real world testing of S8 battery life or are just guessing?

Very educated guessing for 2 reasons.
First: small battery/screen size ratio. Compared to the 3600mAh for 5.5in on the S7 Edge, the S8's 3000mAh for 5.8in is ridiculous.
Second: the new design. This happened the last time Samsung changed the design with the S6, the battery life was horrid on that. Plus this design seems to rely a lot on looking a thin and slick phone from the future and that has probably compromised the battery life.
Edit: and also the 10nm process isn't enough to make a difference, you could remove the processor from the S7 Edge entirely and there wouldn't be a difference comparable to 600mAh because the main power draw on any phone is the display.
Wondering if anyone knows whether using the smaller display option impacts game performance? I am not seeing noticeable difference by eye, but I assume the option changes the dpi and this potentially could effect games much like going from 720p to 1080p would on a pc.
It does not affect the resolution so only the system UI is different. The one-hand mode does not affect performance in any meaningful way either.
