[Poll] Wqhd or Fhd? - Samsung Galaxy S7 Edge Questions and Answers

What are you using?
Did you feel much difference?

FHD for power saving under 15%. WQHD for everything else.
With a live wallpaper like "Solar System Your World" from Google Pixel, if it's FHD you can see the pixels moving.

There's absolutely no reason at all to run anything other than WQHD. Power saving are negligible.

Hello,
How did you manage to install that lwp on your phone? I found a thread on xda and I install the apk but I can not find the wallpaper later to turn it on...

Android 7.0 required. Install like any other app alongside Google Wallpapers from Playstore.

I use the Gear VR, therefore use wqhd.

I use WQHD simply because why have an AMOLED WQHD screen if you won't use it?
Also, what with the usefulness of fast charging, I've found the power changes to be negligible.

tried both, WQHD preferred, especially when you look at the icons and all other stuff on the phone

Yesterday my phone went into a constant reboot loop. I let it go until the battery died because I couldn't do anything else. When I charged it back up it went to a previous backup and lost all my customizations.
Now I cannot put it into wqhd. If I try it just crashes the settings app any advice?

I switch between the two and I've noticed something, I can't tell the difference lol they both look the same to me lol 2nd the battery ? dies a bit quicker running WQHD

The only real difference in battery life between the two is if you spend the majority of your phone usage time playings graphics intensive games. Without games the battery savings from FHD are negligible/nonexistent

For me , both the same . i've been tested and same battery and results .

well this thread is getting more exciting.. let's compare the battery life results between QHD and FHD .. or even with HD

Anyway to decrease screen resolution in marshmallow safely?

WQHD ofc as if you don't game the power saving is not worth to have blurry image. It's just too little of a difference + the phone feels faster/more fluid on wqhd. FHD is if you game more to have better framerate and battery life as the GPU will have a lot less stress. For general use either resolution is of a no problem for that GPU. Cheers!

So why does the power saving profiles want to decrease screen resolution? I'm currently testing, though. I really don't see any big difference in terms of quality between WQHD and FHD.

you will be able to tell more if your wallpaper is a picture you have taken with your camera and not just a bad quality one from Google etc
Wqhd is a lot better
Go to change your power saving mode and customise it
It will tell you even if you go down from qhd to just hd it will only save you 4 minutes of battery

[Q] Downscale Resolution to 1080p to increase performance?

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.

Thank you for pointing this out !
NOMone resolution changer in the app store lets you bring it down to 1080P.

Marshmallow and Always-On 4K

Since Marshmallow supports 4K display at all times on the home screen, etc., it seems that this phone could do 4K all the time.
I've read that some believe they won't even turn it on for Marshmallow because if the CPU/battery drain.
Two questions:
1. Does anyone agree or disagree with this? Maybe it will at least be a setting (in developer options)?
2. If they don't turn this on for Marshmallow and it runs like Lollipop on "Full HD", could a custom ROM enable permanent 4K? Or rooting? Would this even be possible?
Thanks!
Bet that you will return to FHD mode when you look at the battery anyway. Plus most icon resources inside apk will almost certainly stick to xxhdpi (around 480dpi) which won't bring any advantage on 4k screen.
I don't care about battery life. Anyway, does anyone have any answers/guesses to my questions?
Sent from my E6883 using Tapatalk
Well to answer your questions :
1. I disagree as per my answer, it is just not viable for the battery life and plus iirc when i read marshmallow changelog, it only states that it supports 4k but doesn't say anything about native resolution and apk resource resolution addition, the changelog only specifies that it is natively supported but in an upscaled way.
2. If anything, nothing is impossible. But not everything is viable.
Doing QHD at all times and 4K during media is fine by me.
Do it Sony.
I hope via root is possible.
About battery life, I have nice battery packs that maintain the charge for the whole day .....and I suggest any intense user of smartphones having one o more too
Marshmellow comes with native 4k support which will allow developers to turn on 4k on demand.
I don't see a reason to have the the 4k display always on unless its for gaming/movies/viewing high res pics.

What if Sony can let the user decide which resolution their phones wanna run.
Like windows in a separate setting under display user get the ability to select the resolution.
People who don't care 4K they can use FHD and if they like 2K they can have 2K , if not 4K all the time.
But by default gallery and movie apps upscale the content to 4K. I think if they can pull that off it'd be so cool.
Yeah, should be offer 2 modes in display setting, quality and battery life.
4k is already possible! thanks to the guide from the previous post lol, I was able to take a screenshot of my phone running in 4k using a different screenshot app

lag?
now gpu is pushing four K resolution, did u noticed any lag?
also did anyone try xperia z five in trinus VR.its and app which allows you to stream PC games to mobile for VR

But the important one is the dpi though. The 3840x2160 means it's physical pixel count isn't it? But when you look at the density it's obvious that it's still 1920x1080. Cmiiw though.
Are there third party apps that run in 4k mode?
Netflix? Ultraflix? Riptide gp all run in 4k on my shield tv
As hansip87 said.
Also running 4k all the time will increase the phone warmth in hand - try it yourself while watching a 4k movie for an 1h30min
I think it's great that it's possible to run at 2k and 4k all the time but for me it's Battery life others is screen quality /viewing pleasure
After performing the wm size and wm density as shown in the thread fesar posted earlier in this thread, I stumbled upon a few problems that persisted even after restoring to default.
You can read more about my rather bad experiences in the mentioned thread.

Hey which app did you use to take the screenshot with when at higher dpi? Thanks
I changed the resolution to 2K ,and changed it back after half a day ,cannot bear the battery drain

This seems a bit shady imo. Native Resolution @ only Full HD from the box.

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.

Lower Resolution Power Saving

Hey all,
I have bought the P10 Plus VKY-L29 and although it's a great phone, the battery life can be slightly erratic. To combat the issue I've tried the Lower resolution power saving mode but it doesn't seem to do anything - the resolution still stays at 2K
Does anyone else have an issue with the lower resolution power saving mode not working?

Your not going to notice lower resolution on your phone really because there isn't that much difference. ++ If you have viewing mode / density on small and you lower the resolution you aren't going to notice it. You'll probably only notice it if you put viewing mode on big so text and icons are very large and then let it go in ultra power mode. I personally have never tried it, maybe it isn't working but I'm saying you won't know the difference.
I get what you're saying however the thing is the mode is supposed to reduce the resolution from 2K to 1080p. Activating the mode it doesn't do so. .So the initial question still stands. Does the lower resolution power option actually work or is there an issue with my device?

Again, you're not getting what I'm saying. You're NOT going to notice the resolution change. It's different to your computer resolution as your screen is larger on your monitor. Lowering the resolution to save battery is a myth a lot of people rant about.
So again, the resolution is probably lowering but you're not seeing the difference.

On EMUI 4.x the resolution physically changed and this was reported on the About phone screen under the resolution heading. In this case even with low resolution power saving on the resolution heading still shows as 1440x2560 so it clearly hasn't changed!
It doesn't matter about the size of the fonts changing when clearly the resolution hasn't changed at all. You would certainly notice the resolution change as it used to work on my P9 when changing from 1080p to 720p.

Mate, going from 1440x2560 to 1080x1920 you will NOT see the difference!!! Again like i said, it may be broken but I'm telling you, the resolutions are identical. 720p from 108p is a bit of a leap as that's when you start losing HD. If you're that bothered, send it back in.

Hey all,
I have bought the P10 Plus VKY-L29 and although it's a great phone, the battery life can be slightly erratic. To combat the issue I've tried the Lower resolution power saving mode but it doesn't seem to do anything - the resolution still stays at 2K
Does anyone else have an issue with the lower resolution power saving mode not working?

Unless you can, ( like the op ) show us through command prompt that your resolution is still on 2k when in ultra low power saving it's just your word against his. If you both feel that it is not scaling down. Contact huawei. Because ATM there's nothing any of us can do.

1. It doesn't bother me much but i noticed the same behaviour on my device, resolution does not change.
2. I don't know why you keep saying that one can't see the difference, that is not the point here, don't you get that? The point is that no matter if you actually can see difference or not the resolution DOES NOT CHANGE in the first place. When using a tool to show the current resolution it STILL says 2k regardless whether low resolution is being activated or not. Normally - and it DID work that way on the P9P - when you switch to low resolution the device should ask you to reboot and after that it would have the lower resolution, regardless of ultra power saving mode. It clearly does not work this way here, so there seems to be something wrong with this firmware-wise.
3. Afaik OP didn't ask for anyone here to do something, he merely asked whether other people are experiencing this, too.
4. OP, which firmware are you on currently?
I'm almost 100% sure it's not working properly. If it was I should be getting more than 4.5 - 5 hours of sot. Unless there's something going on with the hardware as compared to the Mate 9 that you just can't see in the specs.

I've got nothing to contribute to the thread but I've something to say to you. I've been using 2k 5.5 inch screens since the LG G3 and side by side with smaller 1080p screens the difference is noticeable to not only me but also to my friends who own the 1080p phones.
I think you're trying to say that the phone may well have switched down to 1080p resolution but OP can't tell that. I'm not sure I buy that but I'll get back to you on that.
i am experiencing the same thing on my P9 after update to latest EMUI and P10 since bought. Was working on honor 6, and my p9 before upgrade. so EMUI should be the culprit since different phones having same issue. hope they will fix it as soon as possible. i need to get extra juice from my p10!
some people think they are too smart. Even if OP cannot see the difference, that isnt the point. We are curious whether the feature is malfunctioned. and yes, u can check the current resolution on about phone. Do urself a favor to try and understand before bashing repetitively. it looks too stupid, im sorry.
Yes you can't really tell the difference when it's 1080p because it's being upscaled to a native 1440p screen anyway. There will be a worthwhile difference in battery life from doing that though. It's why the galaxy s8 is configured to do it out of the box.
Those guy who did not have our devices are useless here. I got 2 Honor V8, and before update to Android 7. I noticed the difference when I down the resolution. But when updated to Android 7, resolution is the same whatever I do. I have Honor V8 knt al10 and knt al20. Hope the next update will solve this issue. Regards

If the resolution really changed, when you take a screenshot IT MUST be 1080p instead of 2560, otherwise mean resolution it's still on 2K, and I can confirm that the function to lower the resolution of the screen at the moment is not working > it's not changing the resolution of the screen.
It has nothing to do with "you are not going to notice the difference"
you can do tests on your pc monitor, when you lower the resolution your screenshots will be smaller
I am trying as well to drop the resolution to 1080p and it's currently not working.
Noticed the difference in some apps.

Question: did someone test the battery difference?
I know that the prediction is about 2+ hours in my P10, but does that translate do the real world?
How to lower the resolution in P10 to 720p?
I don't use the low res setting and Accubattery still reports over 8 hours SOT. Mind you, I don't use my device very heavily - maybe browsing and music. Funny thing though, my "new" phones only has about 93% of a full battery's worth of capacity... Hmm...

Just the "low power resolution" setting for now, saw screenshots of an actual setting to change coming in EMUI 8/Oreo.

Impact on battery life - FHD+ v.s QHD+

Hello,
I searched around this forum and didn't find anyone talking about this topic yet, so thought I would start one. Has anyone done any tests or observed the difference in battery usage between FHD+ v.s QHD+ screen resolution on their S8/S8+? Also, can anyone actually tell the difference between the two different resolutions?
Thanks
I can tell a very slight difference in resolution, my fiance has the same phone, so I set them to the two different resolutions and pulled up the same webpage. Next to each other the text is crisper, but not worth the hour and a half SoT that I lose for it.
I can see a clear difference when reading a pdf version of a tabloid size newspaper. Fonts are too fuzzy when using FHD but on QHD they look sharp.
On FHD+ I often notice the icons are fuzzy, they have blurred edges, et cetera. Did not notice any battery impact so far though.
If you want to see clear difference, use it with VR glasses, here even QHD is not enough, you can still clearly see individual pixels even in QHD and forget about FHD, the pixelation is actually distracting. As far as battery goes, I think it depends on a usage: If you play graphic intensive game I can see how rendering extra pixels can affect battery, but often this may be offset by higher frame rate. In more static displays I don't see how this should be making much of the difference, I think all pixels light up regardless of the resolution and it just takes more GPU power to process more pixels, but I could be wrong.

I noticed fuzzy icons on my s8 also however I am using a custom icon set and nova launcher. I was able to fix the fuzzyness by re-selecting/resetting the icons for each shortcut on my launcher. Now regardless of the resolution chosen the icons stay sharp. Maybe the same will work for you if you're also using custom icons that is.

For some reason, even though I'm the highest level tinkerer when it comes to that, I prefer to stick to the stock launcher and icons with the S8. So it was with stock icons.
I know this is the S8 forums, but I've been testing this for the past week or so on my S8+, and I consistently get an extra 1-1.5 hours of SoT when its set at FHD+ vs QHD+. I personally can't tell a difference between the two 99% of the time. Everything is still pretty sharp for me on Nova and a custom icon set (Vopor).
Still not sure which resolution to settle with. It's nice having the extra SoT, but I also feel like I should be making the most out of the gorgeous screen; even if I can't tell a difference most of the time lol... I get about 4-4.5hrs total SoT on QHD+, as opposed to 5-5.5hrs SoT at FHD+.
I have the Canadian Snapdragon version. I set it to FHD+ once and got about 1-1.5 hours more SOT. The text is noticeably more fuzzy, like it's always out of focus. I already get 6 hours SOT with WQHD+ so I just stuck with that.

You actually hit it pretty close. All pixels on the screen are used regardless. Just a bigger sample size with FHD. However, QHD will use a little more battery if you are changing the image on the display. For the fact that it has to draw that many more pixels each time the image changes. Which is millions of pixels. But I believe a lot of static image changing is done by the cpu and not the gpu. where gpu is used mainly for constant motion on screen.
But honestly part of the reason they have such high resolution is for VR. That and to make more sense of taking UHD pics and videos. Most people won't notice a working difference between the two through regular use unless they keep it really close to their face, or have very good eye sight.
So you will see it use some extra battery. Not a detrimental amount more unless you are a heavy user of games and whatnot. Or if you force GPU rendering, then you should see a big difference in battery

Hmm... yes, that is the dilemma for me as well. I could tell that FHD looks slightly more fuzzy compared to QHD. Facebook and Whatsapp apps showed more washed out texts when comparing the two, for example. Would be nice to get more feedback from the others
I am using QHD+ on the S8+, as it is a little larger than the S8. As a techie, using a display at non native resolution is unbearable Kidding, with pentile, you can not tell anyway. I am having good to great battery life and I like small fonts - so I do definetly see a difference and therefore amusing the higher resolution.
I set mine to HD. That's not an option in the poll though.
I enjoy the extra battery life so FHD+ ftw. And on the occasion when I do consume 2160p content on YouTube I simply drag down the quick settings/notification pane and change the phone from Optimized to Entertainment. No big deal.

Or someone with old eyes that can't tell the difference...
Whenever I go into phone maintenance and enable the battery saver thing it tells me I only save like 15mins by switching from WQHD+ down to FHD+ so that's doesn't seem worth it at all. Anybody else seeing the same... It actually tells me most of my battery savings (around a hour) would come from disabling the AOD.
Hmm all this time I've been thinking the difference between fullhd+ and qhd+ would be significant, guess il be changing it to the latter then.
Not even thinking about that lol just i can see the screen and its bright and great i dont care else
FHD+ is my way to go.
I've had it on QHD+ for the last 2 weeks but I never really found any difference and the "fuzzy" things got fixed when I changed the DPI so I have no problema at all. Even if FHD+ provides 30 minutes more of battery life I take it.
