This has been interesting. I've not noticed any change in battery life really, and to be honest I wasn't expecting to. The biggest change has been fluidity of the UI. Things like clearing all recent apps, scrolling, and any of the animations are smoother. My phone doesn't necessarily feel faster, it's just an increase in the quality of the feel of the interface. Silkier I guess haha
[Nexus 6  General] skullassfreak:
I use an app called pixel battery saver. It shut off every other pixel to be off (black). I haven't notice any resolution difference but I do get a little extra battery life on it.
[Nexus 6  General] 414isaiah:
I've changed my resolution to 720p. There are games that I play, which run MUCH better at this resolution. I can definitely tell the difference. Maybe this particular game isn't optimized for pixel dense displays, whatever the reason, gaming seems much better at 720p.
[Nexus 6  General] Scott:
No, this is not placebo. And no I didint buy for the 1440p. I would rather it be 1080. I bought it because it was 6"

If its placebo then how did I do this? 58K. I was doing 54k to 55K before the mod.

I see no difference in Visual clarity at all either.

Battery life. Prolly no difference at all. I will agree with both of you there! The biggest battery hog is the actual screen itself regardless of resolution.

CleanROM 1.5.0 with Elemental X on stock settings.
[Nexus 6  General] Scott:
I will report back on Battery tomorrow however I expect it to relatively the same.

The gains are in the UI. The dialer doesnt lag horrible now...
[Nexus 6  General] selayan:
Also wondering about battery life improvements.
[Nexus 6  General] biggiestuff:
I'm lazy...i want to play my games but I wish there was a toggle button to perform this task.
[Nexus 6  General] guitardoc64:
Ditto that! That would be awesome.

Tapped from Shamu
[Nexus 6  General] Scott:
Working on it :D

Weird enough...

I did not expect better battery... However I got it... I am saving 10% a day. That sounds magical, I know, but I can give numbers to prove it.

-Scott
[Nexus 6  General] Damon13:
Thanks a lot for testing it out, but do you see any difference in the display since it's going from QHD to FHD? By the way Clean ROM is awesome.
[Nexus 6  General] selayan:
That's one difference I see. Stock keyboard here and as you can see its a little bloated by the three dots. You can also tell the icons and the menu bar circle on home screen is a bit bigger. Other than that I don't really see a difference. Haven't ran it for a few days to see what battery life I get.

The ui seems slick too but it was like that on stock resolution too. I'm running a custom darkslide kernel that my friend put together. So far besides the icons being bigger at first, haven't seen drastic differences.
[Nexus 6  General] Damon13:
Thanks for your input, I am going to give it a try. Also any problems with widgets? Darkslide kernel? ummm sounds interesting!
[Nexus 6  General] selayan:
At first the widgets seemed oversized but after a normal reboot they seem about the same. Just try it out, if I get better battery I'll keep it, if I don't see a difference its easy to go back to stock. Look up team ecliptic on here, buck made the kernel for the n6 and I've been testing it for him.
[Nexus 6  General] Damon13:
Awesome! Will def check them out.
[Nexus 6  General] Scott:
There is a minuscule change in positioning and size but in reality the aspect ratio is the same so if you picked up the phone as set to 1080P and had never seen the 1440p you would not notice any issues. The Google keyboard does have the larger dot issue as illustrated above but I dont use it, I use Swype.

And there is a HUGE difference in how smooth the UI is. Just check out the ultra lag Google put in the dialer. Then make mod, then check dialer out again. I see good gains there. The rest of the UI is snappier to me as well.

This is best mod ever!

I did check out 720p but did not see any real world gains of 720p over 1080p so I am keeping my phone at 1080p
[Nexus 6  General] Scott:
Ok full disclosure...

When I posted that I forgot that I had set my WiFi to disconnect with screen off so my battery gains may not be from the mod. However this does not negate that the the UI is more fluid. The 805 just cant handle QHD like I thought it would. Its certainly better than then 801... However 1080P seems like a sweet spot for all processors on the 8xx series.

My bad if I got anyone excited. I'll do some more control testing later in the week :good:
[Nexus 6  General] selayan:
Yea the ui seems a bit smoother but I don't even realize it. I'll stick with 1080p for a few more days.
[Nexus 6  General] Scott:
By all means do. I would be interested in what you have to say / think.

For me its the difference between... Geforce GTX 250 and a Geforce GTX 750.

Big step up when it is "realized"
[Nexus 6  General] Damon13:
There is a def improvement in the smoothness of the UI, waze and maps don't lag like they used to. Battery seems to have improved a bit when using maps or playing games.
[Nexus 6  General] selayan:
So I see that playing games and watching videos it benefits from 1080 because battery is a little better. Normal use though since I don't play many games or use the GPU a lot, its about the same.

I only use maps when I need to use the GPS so they have never lagged for me even when playing around. I'm going to switch to Swype keyboard to rid the 3 bigger dots.

I guess I don't mind either mode but if you play a lot of games or use a lot of video intensive apps then you should use 1080 mode. I've gone back and forth between qhd and 1080 and maybe I can't tell, but the ui to me is the same. Maybe its the kernel I'm running, not sure.

But its cool that we can switch between the modes easily. I think as you mentioned if it wasn't for stock keyboard, people who would pick up the phone in 1080 and not be told it was changed,would not really notice the difference unless they have an eye for the bigger icons. I think after a reboot or two I either got used to them or they have not changed.
[Nexus 6  General] PunishedSnake:
I definitely want to do this but I am waiting for 5.1. That being said is there a way to root without having it wipe my phone
[Nexus 6  General] selayan:
Nope not that I know of. You need to unlock the boot loader and that will wipe the phone. But you can use nexus root tool kit to backup all your media, contacts, apk for apps before unlocking and rooting. I'm also waiting on 5.1 . I'm hoping it will be more optimized.
[Nexus 6  General] fahadali2315:
Amazing. Haven't tested battery timings. But for sure there are some performance improvements. Especially with the flipping dialer.
[Nexus 6  General] JuannTwo3:
I changed it to 1080 some days ago and the battery difference is either negligible or nonexistent. When I first changed it I did notice the difference as things seemed a bit blurry (nothing overly dramatic) but now it seems normal. I don't run a lot of intensive applications so I didn't really notice a difference in performance. Either way, this was an interesting experiment.
[Nexus 6  General] tylerjames09:
can someone please post instructions on how to revert? basically, the proper dpi and resolution to go back to stock. thanksss
[Nexus 6  General] lyall29:
They are in the tutorial at the very end. They are the same commands but with the stock resolution numbers.

su

wm size 1440x2560

wm density 560

stop && start
[Nexus 6  General] juggamonkey:
I use this app to change resolution to 1080p...noticed the resolution change at first but eyes adjusted quickly and ui is defiantly smoother battery hasn't had any noticeable improvement

https://play.google.com/store/apps/details?id=com.nomone.resolution_changer
[Nexus 6  General] selayan:
You can also do

Su

Wm screen reset

Wm density reset

Stop&&start
[Nexus 6  General] bleached45:
You could try tasker to set it to a lower rez for games when they open and then back to whatever res you prefer when you exit the games. Not sure if it will work (do you need to reboot after application?).
[Nexus 6  General] PoisonWolf:
I'm not sure if the wm size command is actually changing the device resolution to what you want, or if it is actually still rendering at QHD, but made to look and report at 720p or 1080p.

IIRC, the only way to actually and truly reduce the resolution is to make kernel modifications to change how the image is drawn, etc.
[Nexus 6  General] selayan:
It still renders qhd by default from the GPU then adjusts to display 1080p. You can see this in a log cat if you record and lock and unlock the screen. It does help with battery somewhat if you are intensely using the GPU. But the GPU still has to push those qhd pixels rendered by default.
[Nexus 6  General] lyall29:
This mod does seem to make my Nexus faster/more fluid, and the resolution doesn't bother me at all. So far so good!
[Nexus 6  General] Megaflop666:
The GUI definitely feels much smoother since I made this change. Battery? Eh, I've noticed no drastic difference.
[Nexus 6  General] bigkevbosky:
This definitely makes an improvement in fluidity on stock based roms. I can't tell a difference in sharpness either so its a nice mod. It doesn't seem to make a noticeable effect on CM 12 based Roms though.
[Nexus 6  General] Megaflop666:
Maybe pure coincidence, but I tan into a problem with this mod...

After making the change everything was great, very fluid GUI, etc. I had several times I sent texts and the phone would freeze for about 10 seconds. During the freeze I would hear the sent bleep and about 10 seconds later the screen would unfreeze and catch up. Since it was the only mod I had done before the behavior started, I did a wm reset and have not had the issue since.

Anyone else run into this?
[Nexus 6  General] guitardoc64:
I ran into an issue with TouchPal keyboard. It didn't resize to the display and was unusable. I went back to stock.
[Nexus 6  General] grayson73:
So performance will increase, but battery life will not. That's similar to what they found with the G3. Almost 50% 3D gaming increase, and only 2% battery life increase:

Has anyone tried downgrading Nexus 6 to 720p?
[Nexus 6  General] fethi2:
You can always buy 3310 :)
[Nexus 6  General] aalupatti:
So difficult to find a new one [emoji12]
[Nexus 6  General] PJcastaldo:
Smh.. You guys drank the kool aid and the snake oil. Any gains you think are making your device faster or more fluid or whatever.. Its in your head.
[Nexus 6  General] doitright:
I haven't tried this and won't, but the results make absolutely perfect sense.

Think about it for a moment;

The Adreno part handles graphics. Its job is to calculate triangles as fast as it possibly can. The higher the screen resolution, the more triangles it has to calculate. Since it can only calculate a fixed number of triangles in a period of time, having to calculate a greater number of triangles per *FRAME* means that it takes more time to calculate each frame, number of frames per second (FPS) goes down.

Any time the GPU can't produce frames FASTER than the rate of consumption, it is pegged. It can still be pegged at a lower resolution, but be producing more FPS *while* pegged, hence negligible battery savings.

When you are operating at a lower set resolution, obviously the screen itself has to output the same number of physical pixels, but the GPU doesn't have to calculate all of them.

These AMOLED displays cheat on resolution to begin with. RGBG matrix means that the real resolution is actually only 720x2560. Except for green, that is, but green is only one component of 3. They claim that your eyes can't pick up the lower R/B resolutions, but you can. If you knock the resolution down to 720x1280, then you are actually matching the resolution in the horizontal direction, and although you are actually cutting the vertical resolution in half, the resulting pixel density actually ends up being the same as you get in horizontal direction.

In other words, at 720x1280, each individual pixel is SQUARE and looks like this;

RGBG

[Nexus 6  General] Saad Ali:
On what rom do you get this option to change resolution?
[Nexus 6  General] chenxirui1995@163.com:
how to return it？ ：（（（
[Nexus 6  General] StrizzMatik:
Download a terminal emulator from the Play Store. In the terminal, type the following (Requires Superuser access):

qHD (Stock)

su

wm density 560

reboot (if it doesn't automatically reboot)

1080P

su

Battery

It lasts longer battery with low resolution ?
[Nexus 6  General] furrycurry:
Read more literately with low resolution?
[Nexus 6  General] Pilz:
The pixels are still being used so no it wouldn't get better battery life. You are only changing the resolution of the display not how many pixels are being used to render it.
[Nexus 6  General] MrIc3c0ld:
Problem with density in some apps

Hi Folks,

I changed to 1080p and Density 420. it looks nice but some apps like google sheets and co. Don't look right. Also the copy paste menu vor the three dots in the keyboard are huge.

Is there a fix for that?

Thanks in advance!!!

:)

Cheers
[Nexus 6  General] thomase00:
Shouldn't developers already be using the hardware scaler to render 3D games at a lower resolution? Console developers routinely render to a virtual framebuffer at a resolution lower than 1080p and then upscale. Android developers have GOT to be doing this in order to maintain decent frame rates for their games. That being said, if the frame rate is "good enough" while rendering at 1440p, they might not be motivated to go the upscaling route. This is unfortunate because such a high resolution on such a small display is probably not much of a benefit for a 3D game. Rending 2D text and icons is a different story...

http://android-developers.blogspot.com/2013/09/using-hardware-scaler-for-performance.html

For reference, my 2013 Moto X (Adreno 320) rendering at 720p gets nearly the same on-screen graphics benchmark scores as the Nexus 6 (Adreno 420) rendering at 4x the resolution.
[Nexus 6  General] ps000000:
The home screen icon look bit blurry on 1920x1080 but I think this mod is good.:laugh::laugh::laugh:
[Nexus 6  General] Darian71:
Stock Resolution screen, rooted and running UberMallow ROM now with despair kernel OC'd to 2.7MHz.
[Nexus 6  General] grandmasboy:
It actually is. Changed between 1080P and 720P, and even though 720P is obviously less, with even less DPI, it comes out a bit ahead in my eyes.

The only downside is some of the stock stuff doesn't really support resolution that "low", and some things get cut off.

Not an issue if you use third party apps.

Kind of funny that google's stuff won't work well at 720, but third party software has no issues.
[Nexus 6  General] doitright:
It isn't that they don't, Nexus 4 is 720p, and in fact, Android works very well at considerably lower resolutions, like 480. The problem is that there are more differences in the system image where it was compiled to the higher resolution than just the dpi override you are doing. And in fact, Google even produces many different gapps packages based on target resolution. You could get a perfect output, but it would be a highly customized build.
[Nexus 6  General] Semseddin:
I've put HTC M8 and Nexus 6 side by side and run Marvel Contest of Champions on both. The edge graphics of the characters on the HTC M8 with 1080p is pixelated jagged edges while Nexus6 with 1440p you can't find any pixelated stuff on the edges. So, i am not buying 1440p = 1080p no difference story at all.
[Nexus 6  General] doitright:
You do realize that you are comparing two DIFFERENT phones to each other, don't you? The GPU on the Nexus 6 is a lot more advanced than the M8. Your side by side comparison means absolutely unless you are comparing over the claim, which would require you to have two Nexus 6's side by side with the change implemented on one of them and the other all original.
[Nexus 6  General] Semseddin:
Yes, i do and you are logical in your argument. However 1440p and 1080p have no difference is just a pink story.
[Nexus 6  General] ivanov13:
CyanogenMod 12.1 powered by ElementalX

Resolution: 720x1280

Density: 280
[Nexus 6  General] doitright:
Huh? That benchmark shows *MASSIVE* difference in score. You are roughly 6000 (SIX THOUSAND) points higher than normal Nexus 6 due exclusively to improved 3D performance. Typical 3D performance on Nexus 6 is about 17000, yours shows over 23000.
[Nexus 6  General] ivanov13:
I was pleasantly surprised when I saw the score.
[Nexus 6  General] ivanov13:
This is what I get with ElementalX oc to 2.8 GHz with stock resolution.
[Nexus 6  General] doitright:
That appears to be a much more modest improvement. Only 2k on the graphics (vs 6k for the resolution change), no doubt more specifically with respect to CPU-bound graphics tasks.
[Nexus 6  General] ivanov13:
I apologize for incorrect info. I just looked at the pic I posted and realized that resolution is 720x1280. Here is the stock 1440 with Elite kernel no OC
[Nexus 6  General] Ygor Cortes:
I was using it at 1080p and it was worth it for a while, but then the UI bugs really started to piss me off and the gain in performance was not that huge because Marshmallow is fluuuuid and I don't usually play games. But the difference in heating is kind of big, so let's see... I changed the resolution back to the stock just now and will test it again. It would be really good if the UI bugs weren't there.
[Nexus 6  General] YevOmega:
Everything except Swiftkey seems to have scaled fine. Swiftkey is super huge, and I tried uninsta and reinstall. And yes, I rebooted. Help!!! Thanks!
[Nexus 6  General] danarama:
I dont think there is anything you can do. Some keyboards just dont respond well to this.
[Nexus 6  General] YevOmega:
Nuuuuuuuuuuuuu!!!!! Thanks!
[Nexus 6  General] supergear:
I don't see any reason to change resolution
[Nexus 6  General] simms22:
many falsely think that lowering the resolution will raise battery life.. as i said, falsely.
[Nexus 6  General] angourakis:
change DPI on system/build.prop and voilà, it should work fine !
[Nexus 6  General] benleonheart:
Skipping on this.

I bought my Nexus 6 to display that gorgeous 2K screen.

If I want 1080p I'll power up my Nexus5.

Not to rain down on your parade, it's an awesome find. But for 15 minutes more? hell, this thing has quickcharge. 15 minutes plugged in gives you a whole lotta juice.

Increasing performance with this mod? it's negligible IMO.
[Nexus 6  General] jmgib:
I think most people are missing the point. The benefit to lowering the resolution should be to increase performance, though this may also be a negligible benefit. Any power savings would be nil, since the pixels still have to be lit.
[Nexus 6  General] simms22:
lol, theres no performance increase when lowering the resolution, if someone thinks there is, then i challenge them to a benchmark battle with my encrypted n6 :)
[Nexus 6  General] Strephon Alkhalikoi:
Are you one of those that chooses to run their 1600x900 laptop display at 1280x768? I don't know of anyone who would do such a thing, so why in the heck would you do it on your smartphone? Regardless of the resolution you've set the screen at, the GPU still has to drive all those pixels. You won't see any improvement in performance, but only get larger images.
[Nexus 6  General] jmgib:
Oh, don't misunderstand, I'm not doing this on my phone. It's just that most of the negative comments in the thread seem to be saying it doesn't help with power saving. I don't think anyone is making that claim at this point. The argued benefit seems to be saying it helps performance.
[Nexus 6  General] Strephon Alkhalikoi:
Well, it doesn't improve performance either. It's a waste of time and energy.
[Nexus 6  General] simms22:
oh, believe it ot not, mamy people still think itll help their battery.
[Nexus 6  General] electricpete1:
I'm kind of new to this. I built a spreadsheet to try to make sense of the numbers. Here's what I came up with:

Name dpi W H ( H/.W) ( W/dpi) (H/dpi) Diagonal (*)

------------------------------------------------------------------

Native	493	1440	2560	1.778	2.921	5.193 5.958

Stock	560	1440	2560	1.778	2.571	4.571	5.245

“1080p”	420	1080	1920	1.778	2.571	4.571	5.245

“720p”	280	720	1280	1.778	2.571	4.571	5.245

Columns of above "table"

(H/W) column just verifies the apsect ratio is constant among all options.

(W/dpi) column calculates the physical width if we assumed dpi represents physical pixels per inch (inches = pixels / pixels-per-inch)

(H/dpi) similar to above

Combine width and height to calculate diagonal*

* Diagonal = sqrt({w/dpi}^2 + {h/dpi}^2)

"Native" I guess is where you don't lie to Android... you set the dpi equal to the actual pixels per inch that correspond to physical screen dimension (accordingly this is the only one that predicts the actual 5.96" diagonal dimension).

Any other dpi setting other than native fools Android into thinking our screen is larger or smaller than it actually is, so it will adjust size of displayed items accordingly....

If we tell Android we have a higher dpi, it thinks the screen is smaller so it enlarges things (icons etc) to help us see them.

If we tell Android we have a lower dpi, it thinks the screen is larger and can tolerate shrinking things more to fit more onto the screen (like a tablet).

I put 720p ad 1080p in quotes based on doitright's comments

I don't have great eyesight. I can't see any difference from the 1440 down to 1080 and I can only see a small difference going down to 720. So there's not much downside at 720p for me even if the benefits are marginal.

Using 720p with the proper scaling 280 as above everything is the same size as before. Apps that give me a slight hiccup are:

1 - Tasker scenes/menus

2 - Gravity Box custom navbar key (app launcher) menu

3 - Zoom widgets

I can deal with these... Minor glitches and still very readable. I'm going to keep 720p for awhile and see how it goes. If I don't see a noticeable effect, I'll probably go back to 1080...I don't see any point in going all the way back to 1440 with these eyes.
[Nexus 6  General] Diatomix98:
As a previous owner of Xperia Z, I have to say that it actually affects the performance quite a lot especially in terms of UI smoothness and gaming performance. There was a huge difference in performance on 720p which the GPU obviously is struggling so much on stock 1080p. However, you guys are right about this when it comes to the 2k screen era, newer processors like the Snapdragon 805 and above in our phones are able to handle such high resolution with no sign of struggling. So my conclusion is, it is useful but only on older processors. :)
[Nexus 6  General] hackthis02:
You could do this with Tasker.
[Nexus 6  General] benleonheart:
Same, running an encrypted N6.
[Nexus 6  General] ncwildcat:
Would doing this help with screen tearing issues on custom kernels
[Nexus 6  General] Strephon Alkhalikoi:
It could make the tearing worse. Honestly, any perceived benefits I believe are due to the Placebo effect.
[Nexus 6  General] electricpete1:
The comments about benchmark battle seemed strange to me since of course there are many more variables between phones than the screen settings. Why not compare the same phone before/after changing the resolution. Those type numbers were posted at beginning of thread and as I recall and showed perhaps marginal improvement. It might be worthwhile for me if it introduced no adverse effects, but I just came up with a big adverse effect that's a deal breaker for me...

Google camera app "lens blur" effect (keeps subject in sharp focus and blurs background) post-processing screen (where you re-select area to focus and adjust intensity of effect) was totally unusable for me at 720p, 1020p and even stock 1440 with custom 600 dpi (600 dpi was my attempt to make things render a little larger). Only when I set it to stock 1440 and also stock 560 dpi was it usable. So I'm back to stock settings.
