Does switching display resolution impact the battery life of the device? How significant is it?
My experience is not much. Higher res will make higher demands of the battery. I use WQHD+ instead of FHD as not really seen much of a hit though that said there is not a lot between either mode. I should try FHD+ again.
Not that much, I always get about 6-7 hours of screen on time with WQHD+ on FHD+ is about 30 min more.
But on the other hand the difference in actual resolution is not that high either. So you will barely notice any difference in sharpness.

Hi,
1st off I love this phone. I am extremely pleased and have zero complaints so far. Buttery smooth too....
My Question is how is it possible that the screen resolution is adjustable? Does the display turn off pixels? Does it merge pixels? Please enlighten me..
Thanks,
Joel
I'm pretty sure it must be 'rooted' first to allow those changes.

Sorry even though u r pretty sure. This info is wrong. U DON'T need root. Just like samsung graxe ui. On LG V30 u go to display - screen resolution and switch between 720,1080 or qhd+.
But the OP never asked if changing resolution was possible. He most know that we can already change res in the setting. What he is asking is HOW does lowering resolution works.
Im not sure about this but from tv or any pc monitor u can upscale to max reolution of the monitor or downscale to a lower resolution. The pixel are still on but the screen is not push very hard.
Amoled are very power effecient and this has been discuss in the S8 forum for quite sometimes. After all the testing the xda members have been doing it seems that going from QHD down to 1080(full hd +). Doesnt save that much battery (around 5% better battery)
Actually I'm wondering because on a 1080p TV, when you feed it a 720p video, the TV stays 1080p. The video is just enlarged to fit the 1080p display. On the V30 I'm under the impression that the display will actually change. Kinda like having a 3 displays in 1...

U wont see a smaller screen. The screen will stretch out edge to edge but it will look very blurry if u do 720p. Not so much in 1080p mode. So u can say that the software upcales lower resolution. Just like riptide 2 which u can lower or max res in the setting of the game.
Wait, so the software downscales? You sure? Just Android or all apps too? I don't think so. How could software down scaling effect battery life?

The screen is cap at 60 hz. Let say u are playing a game ( this goes with the ui smoothness aswell). Since the screen is cap at 60hz means that the fps is up to 60fps max/cap At 1080p is you play a game that can reach 80fps(cause is not pushing QHD pixel) the cpu/gpu doesnt have to work has hard. So instead of doing 80fps it only have to do 60fps meaning that cpu/gpu doesnt have to work 100% since is able to maintain easily the frame per second require from the 60hz screen.
This is why the new RAZER phone with 120hz screen can do 120fps.
Now if u increase the screen to qhd (1440p+). The same game with higher resolution the frame rate will be much lower. Now. The game probably is reaching 55fps instead of 80fps max (is an example). The screen is 60hz (60fps). So the cpu/gpu is gonna be working 100%. Much harder cause is trying to reach 60fps but it cant. Which equals more power comsuption, hotter device and also cpu/gpu throlling cause of the heat.
Can anyone share some opinions about smart resolution based on he's usege,just I'm curious how is better with or without that toogle and is for real helps for battery life.
I was also curious about that .... I have used smart resolution since the beginning and now i will change to fhd+ to see if i get a dip in SOT.

my mate 10 pro is New, I take it yesterday, using smart resolution for now, test fhd+ later
I am using smart resolution, and I am wondering the same. How is the results from the experience from using FHD+?
Maybe it switches to 1080p when you play games. That's the only reason that I can think of that would help prolong battery life.
I'm using Smart resolution too and to be honest I don't see any big difference from my day to day use using FHD+
Regular mate 10 here and I see no difference when using smart resolution. The only time I noticed anything was when watching a video with numbers in the picture...the numbers were a little jagged along the edges whereas the rest of the image stayed the same. Changing to the highest resolution made the numbers sharper/smoother while the rest of the video image remained the same...to my eyes.
i only use HD+ and its still sharp as ****.
hd+ is more then enough for me.
I changed it from smart to FHD+ and have not noticed any big hits on battery life. Still goes a whole day with 5-6+ hours of SOT
I was just wondering what display settings does everyone use and how to get the best performance out of the display. If anyone can tell me all the things to turn on and off for getting there, it would be great.
Thanks

I use the best settings possible, what's the point In having a good phone with the best display if you ain't gonna use it
Exactly. When you say best performance, what are you looking for? Higher synthetic benchmark scores to brag to your friends who also don't understand benchmarks, or the best looking display to actually USE the phone?
Do what makes sense for you. I keep mine on HD+ (720 pixels in the short direction) because my eyesight isn't great and I can't tell the difference. Samsung pushes the higher resolution because it looks good on paper (specsmanship), however I am doubtful that most people (even with good eyesight) can tell the difference between FHD (1080) and WQHD (1440) pm this size phone.
Other people don't matter, check for yourself. I would look at straight diagonal lines and text. If it looks jagged, then go to higher resolution. If not then try lower resolution.
There is a small battery gain from using lower resolution. You can see what Samsung thinks the battery gain is by going to the battery power saving screen and note the savings projected in the "apply" button at the bottom. Change the screen resolution and the projected savings in the apply button will change immediately. The change in projected savings between two modes presumably represents the difference in power consumption that Samsung estimates. For me it is rough ballpark 10 minute life saving from 1440 to 1080 and another 10 minute saving from 1080 to 720 (when checked with battery near full)

I agree with you. I believe that's what my original question was. What are the settings which will give me the best display performance?

I was referring to display performance, which includes having the best visually appealing display settings. I do not care about any benchmark scores. I believe most people have stopped caring about that a while back.

Thanks. I do keep my resolution at WQHD at all times. I was wondering about all the other settings such as Settings -> Device Maintenance -> Performance Mode -> High Performance (I've heard this is needed to get the best display) and other things such as what screen mode looks the best and most saturated (Adaptive, AMOLED cinema, AMOLED photo, etc.) or if there are any other settings.
Guys what settings you keep in adaptive display?
The difference between HD and wqhd is easily noticeable, I have mine on mac settings and the screen is stunning

I was wondering, what resolution are you using?
I've started with WQHD+ and moved to smart, since i didn't noticed much difference(didn't really test battery life, just DPI and fonts).
What resolution do you use, and why?
I've always left it on smart resolution. Never found a reason to change to a specific option.
Im running it on FHD.
Couldn't notice the difference.
I´m considering to buy this phone and need some input from owners.
1. How is the battery life SOT on 90 HZ ?
2. Is there any EIS in 4K?
3. Is the Display brightness enough to use the phone i direct sunlight?
Thank you for your time!
Brightness is lower than the competition. If you need a bright display you can use in sunlight outdoors, buy a different phone.

How about 4k video and battery life?
Sot in 90 Hz is about 10% lower than automatic one. I use the smartphone principal for gaming and I obtain about 9 hour of sot.
The display is not really bright and usable under sunlight but is pretty good .
I don't use a lot camera for videos... I'll try and tell

Got the phone and I'm positively surprised!
Great stability in 4k to.
Battery life is too early to tell.
I started getting 8+ hours of screen time over 45 to 48 hours on a single charge.
On 90 Hz.
