Hmm didn't work. Stock 6.0.1. No root.

See attached screenshots.
[Nexus 6P General] evocalante:
Didn't work either. I tried with the nomone resolution changer and a no go. Does it make a difference if your systemless root?
[Nexus 6P General] cgjjaf:
Same thing here, I tried it and it didn't work. Stock, no root.
[Nexus 6P General] Chord_Hugo87:
Did you guys enable USB debugging and try doing it through adb
[Nexus 6P General] NordomTT:
Isn't this just changing DPI? I suspect those info apps show PPI, which doesn't change because it depends on hardware.

Textdroider_dpi is the app I used with OPO, and it worked fine. You do need root.

The first thing you notice after changing dpi is that icons on the main screen change size (to the eye).
[Nexus 6P General] Chord_Hugo87:
No it is what the title says it does. And yes in order for it to scale right u have to change DPI.
[Nexus 6P General] Matrix_19:
but there are still 1440p pixels on your screen to handle even if you change the display resolution

so I'm not sure if it will really help with anything.
[Nexus 6P General] Hrithan2020:
In terms of display power consumption, yes there wouldn't be any change. However, the GPU and to a lesser extent CPU doesn't have to be driven that hard to run the display on a lower resolution (s/w wise), hence theoretically leading to better performance, more efficient CPU & GPU. This can lead to battery savings as well potentially. (could be marginal, but needs to be tested)
[Nexus 6P General] vaesat:
Anybody tested? Can you extend SOT time? Also 1080 would not be the same proportion...

Enviado desde mi Nexus 6P mediante Tapatalk
[Nexus 6P General] Chord_Hugo87:
I found that if the phone heat up, battery Drain significantly faster and charging time would be slower too.
[Nexus 6P General] Chord_Hugo87:
did you modified the DPI? if you did what I said then there shouldn't be any distortion.
[Nexus 6P General] vaesat:
Have not tried yet. Maybe tomorrow. Can you confirm more SOT time?

[Nexus 6P General] Chord_Hugo87:
Did u read the OP? I have a feeling you dint.
[Nexus 6P General] vaesat:
Yes I read the OP. I read the whole thread. The issue is that actual no one is confirming better battery. Most do not get it to work. Hope to have some extra time tomorrow to test it. Under the theory it should work. My MacBook pro retina has lower battery consumption under lower resolution settings. This should be the same
[Nexus 6P General] npras42:
Let's re-phrase that. Not one person so far has confirmed that this works and it definitely does not on Stock, Unrooted with Terminal or adb.

Spam.
[Nexus 6P General] nardow:
Theoretically yes
[Nexus 6P General] deani77:
Testing out this mods on N Stable. Set the smallest width to 443dp. All my apps working fine including SwiftKey... Will monitor my battery life with this mods.
[Nexus 6P General] ArmStrongDickPunch:
Can you post a link? And does it work on NRD90M Android 7.0?
[Nexus 6P General] RockwellB1:
I found a tool on this site awhile back (been using this since my Note 3 I think), still works with the 6P on N. Of course N allows you to change things in the settings, but maybe you need to take it a step further. It uses the ADB commands, but makes it as easy as typing in the dpi and resolution you want. I can't find where I got the download from anymore, so I've provided the zip below on dropbox.

[Nexus 6P General] deani77:
Been using this mods since last week. What I noticed my phone a bit cooler but battery life is the same as using full resolution.
[Nexus 6P General] Jongla:
so I changed the resolution and dpi using terminal emulator.

it worked fine.

but i am having some strange problem with Instagram and some other app like this.

What can i do to make them work normal.?
[Nexus 6P General] Jongla:
None?
[Nexus 6P General] Citizen_Snips:
You could just return to stock settings? The battery / heat savings here will be negligible, at best. If you want to cool your phone you could always just use a custom kernel to throttle it more aggressively than stock. I live where it gets to be ~105Ã?Â°F outside with like 96% humidity. I've never had this phone overheat even one time and I work outside in the sun all day long. Phone running Spotify the entire day and not once has it overheated to the point of an emergency shutdown.

No disrespect to OP or anyone else here, but warm a hotplate up to 80°F and another one right next to it to 81, and go all the way up to 85°F. Place your hand on one, remove it and place it on another. Blindfolded, with the plates out of order. Yeah... not only won't you be able to tell which is which, you're not going to notice a difference at all. So if it's conflicting with your daily usage, remove the mod. Like I said you can use a custom kernel or modify your thermal throttling settings to keep the phone cooler.
[Nexus 6P General] Jongla:
The resolution actually starts to matter when you are playing hi resolution games.

I play a lot of games,and i can feel the smoothness difference between 1080p and 1440p when playing them for a long time.
[Nexus 6P General] frnt:
could anyone benchmark our nexus 6P with 1080p resolution?

it would be nice if there's a way to lower the resolution automatically when gaming only [like on windows PC]
[Nexus 6P General] yaojinjia:
Is there any negative impact on the hardware? Or does it benefit the battery life?
[Nexus 6P General] emiwonder:
there is no negative effect on hardware. Battery life won't be drastically improved, however, this mode gives you an opportunity to lower your CPU settings as FullHD display does not need that powerful CPU
[Nexus 6P General] jeremmie:
Hey im so noob. I dont how to force my resolution to 1080p pls help.

Im currently running 6.0.1 using cm13 pls advice. Hate my phone runs too hot
[Nexus 6P General] Acres4:
Why would you want to do this?
[Nexus 6P General] harshal10398:
I downscaled to 720x1280 and set density 246. Guess what, I'm getting one hour of more sot while browsing nd chatting, also 1 gb of ram free all the time and cooler, faster device. ?

I think i should not run after qhd screens from now on. 1080 is good ?

Thanks op
[Nexus 6P General] DorianX:
Actually you scaled down to 720p not 1080p

[Nexus 6P General] Batfink33:
Better performance, lower heat and better battery life.
[Nexus 6P General] infamousvincci:
Thanks for this guide. I can see and feel a better performance and fluidity with this mod. Im not experiencing any of the issues that are discussed from earlier posts thankfully. Im not a swiftkey user nor android pay user so im cool.

Testing battery life now. :)
[Nexus 6P General] mEmNiC:
SwiftKey works perfect for me after doing this.

All I did was to write it in terminal emulator, accepted root with supersu and after that I was golden.
[Nexus 6P General] jeremmie:
Can someone pls explain this to me.. As of now i dont have a desktop pc. Can it be done via nexus 6p itself?

Im currently on

Cm13
[Nexus 6P General] emiwonder:
yes you can. Just download Terminal app from Play Store, then type in wm size 1080x1920 and wm density *input the number that will satisfy you*, then reboot your phone.
[Nexus 6P General] jeremmie:
Thanks mate!!
[Nexus 6P General] infamousvincci:
My phone was responsive before, after this mod, it became even more responsive...
[Nexus 6P General] Clienterror:
Is there any way to see if it worked?
[Nexus 6P General] Winb33:
Changing on the fly with .sh

Funny thread .. :) I' ve started playing with this mod this morning ..

My feeling is having a faster phone on games , about battery consumption no report as it' s too early for me ...

I've take time to make a really easy way to use this mod on the fly without reboot !!!!

U need ROOT to use my files

_First Download Root Browser (free on playstore) and open it first time to give root access.

_Flash THIS zip in recovery (This will put 2.sh files in /sdcard/ folder ) (you can also extract files and put then manually where you want)

_Open root browser go to /SDCARD/ cllick on 1440p.sh or 1080p.sh and EXECUTE ... Bam Resolution changed !

Easy way to use it before gaming session :) Thanks [MENTION=6923150]Chord_Hugo87[/MENTION] for this tips !

Have fun
[Nexus 6P General] oussamalabbize:
I didn't expect such a difference, but here we are, the performance is so great, no difference in screen quality, all apps are working. I'll wait few days to see how the battery drains.

Thx a lot !!

P.S : I'm running the latest carbon rom weekly, wtih elemental x kernel.
[Nexus 6P General] infamousvincci:
Right? So much more responsive lol
[Nexus 6P General] rfvreynoso:
Winb33 and oussamalabbize, please do come back after you have made an assessment and give your thoughts. I used your .Sh files winb33 and changed my resolution to 1080p to test for myself, thatnks for files winb33.
[Nexus 6P General] Winb33:
After 2 day of use changing resolution several times in a day eat more battery. Perhaps was less if reboot and stay with it for a day. I also had few prob with my kernel settings app (not due to this change) so was hard to see a real difference. I've tested with real racing and boombeach phone in 1080p feel smoother and colder during games session.. but i didnt bench so just my feeling.
[Nexus 6P General] oussamalabbize:
Yeah, that's right ;)
[Nexus 6P General] lordulrich:
Has anyone experienced a visual bug in recent apps? Im on 7.1.1
[Nexus 6P General] deani77:
What type of bug... Recent apps look bigger?
[Nexus 6P General] blitzkriegger:
I tried scaling back to 720p/246 dpi a few days ago just to see if doing so will yield any significant effect on battery life, performance and temperature. I did the same things I do on the phone like play games for 1-2 hours, download stuff, browse the web, etc.

At the end of the day there weren't any noticeable differences with regards to battery life and temperature between 720p and 1440p. Performance-wise while graphics seem more fluid when doing stuff, the resolution change is pretty noticeable. In the end I'd still prefer normal resolution as there are no ground-breaking benefits to downscaling at leastcfor my experience.
[Nexus 6P General] Hymizzle:
Can you share wallpaper, thanks.
[Nexus 6P General] Krhysten:
I did not notice significant changes in battery life, but there was a remarkable performance gain. Just check on any benchmark app.
[Nexus 6P General] Dbj.Dhaval:
Yes
[Nexus 6P General] Pipiou211:
Thank you Winb33!

Guys I suggest you using this, I can imagine that your GPU will work less to render things at screen, working less and still geeting paid sounds nice. My battery drains the same but the heat/lag after x minutes of gaming dissapeared

Do not use it if you are using your 6P for VR! Enough said!
[Nexus 6P General] hecksagon:
Shouldn't really see much in the way of battery savings because the display (biggest power consumer) is still displaying a 1080p image scaled to 1440p. Performance requirement delta between 1080p and 1440p outside of games/vr is pretty insignificant, so don't expect to see any savings there. Anything saved while playing games is just being used to render at a higher framerate, unless you are hitting 60fps.
[Nexus 6P General] deani77:
I think that was normal for this mods. I have it with stock and custom ROM.

---------- Post added at 05:57 PM ---------- Previous post was at 05:55 PM ----------

If I'm not mistaken Samsung also implemented this mods in their nougat update for their Galaxy line phone.
[Nexus 6P General] hecksagon:
They also implimented a grayscale battery saving mode. In many cases this consumed more power because it filters all colors to a shade of white, only varying the brightness. White requires all 3 subpixels for each pixel to be lit, and nothing burns through power on an AMOLED like white.

Point is, Samsung implements features that make good marketing points. The grayscale was part of their "Ultra Battery Saver" feature. It makes such a dramatic change in the UI that it convinces people it must work or Samsung wouldn't implement it.
[Nexus 6P General] KindofBlues71:
I did this mod to my 6P, just flashed the 1/21 build of Pure Nexus and I can't use the nav buttons in one handed mode.
[Nexus 6P General] Krhysten:
The same here... Probably "One-Handed Mode" was built upon the original pixel density. :'(
[Nexus 6P General] vivektyagi20:
Is it just me or does reducing resolution display bigger screen font when in multi tasking window? (Attached screenshot)[IMG="Resolution"]https://goo.gl/photos/GGMkhmQVK7h67h2g9[/IMG]
[Nexus 6P General] Sheetzie03:
It does, but not a big deal ya know
[Nexus 6P General] yuva_cool:
Yes any fix for it?
[Nexus 6P General] deani77:
AFAIK there no fix for it since there is no custom ROM that supported it.

[Nexus 6P General] projektorboy:
HTC 10 - Fully Stock 8.0 Oreo

Plugged my phone into my computer and fired up adb

"adb shell wm size 1080x1920" worked correctly after reboot. I took a screenshot and it is indeed at that size.

I also use the "smallest width" in dev tools to go 360 because i prefer that
[Nexus 6P General] Will008:
I know this thread is old.

I had a OP6 which I sold to get the pixel 3XL then had trouble with my order and using my 3years old 6P again now. I ran this mod before when the phone was fairly new and there not much difference in performance or battery.

But after 3 years with the 6P now it stutters and laggy, after running this mod (I run it on 720P though) the phone's performance has significantly increased, it rarely gets hot. Battery runs better but I think this is coming from the fact that the phone doesn't get extremely hot anymore. It's like having a brand new device now.
[Nexus 6P General] sjandroiddeveloper:
How much improvement in battery life you noticed ? Also does 720p look pixelated
[Nexus 6P General] Will008:
My (SOT) has literally doubled running the screen on 720P without changing anything else.

In all honesty I think the majority of the battery improvements are coming from the fact that the phone doesn't heat up as much anymore. When the phone heats up the battery heats up drains faster.
[Nexus 6P General] sjandroiddeveloper:
Is 720p very noticeable, like pixelated?

Also resolution is 1280x720 and what's the density u set ?
[Nexus 6P General] Will008:
The display doesn't look pixilated at all. Difference isn't much to me. The trade off is definitely worth it. The recent apps all looks magnified though but doesn't bother me.

---------- Post added at 06:47 AM ---------- Previous post was at 06:21 AM ----------

Commands:

adb shell wm size 720x1280

adb shell wm density 280
[Nexus 6P General] sadmar1:
i need the Name of the files that’s Responsible for resolution so i can reset mine to default using twrp .. i cant accesses my phone i cant use adb
[Nexus 6P General] famaia:
No wm command

Trying to do this on Pie Pixel Experience ROM but got:

/sbin/sh: wm: not found

Any way to fix this?
[Nexus 6P General] Lawlrus:
Why are you trying to do this ?
[Nexus 6P General] famaia:
Trying to see if it improves battery life.

Having 2 hours of screen on time, probably battery is gone already... 2 years old heavy work use.
[Nexus 6P General] Lawlrus:
To gain what, another 10 minutes sot? If this was some kind of magical fix to get an extra hour+ on this device you wouldn't have had to resurrect it after six months of zero posts.

You're looking at the wrong place to get better battery life, look at the garbage coded social media and messenging apps you're probably using.
[Nexus 6P General] Will008:
I can confirm it helps, I had to use my N6P as my daily driver in-between my OnePlus 6 and pixel 2XL and once I scaled the resolution down to 720p the SOT was much better and the phone was smoother overall. The battery savings don't come from the lower resolution directly but when the GPU isn't pushed as hard on lower resolutions the phone doesn't heat up at all. Normally the phone heats up with normal use and the heat around any lithium battery leads to it losing it's charge faster.

This trick wouldn't work on a newer phone like the pixel 2xl/3xl for example as they don't heat up with normal use as the 6p, thus there will be no battery savings.

I agree with you about social media apps though, I use greenify to make sure they are completely off when not in use. I also use naptime.

[MENTION=9882395]famaia[/MENTION] when I used this mod my SOT almost doubled with my normal use, no gaming though. I also used ABC ROM which runs smooth AF on the 6P.
[Nexus 6P General] faris:
i also get a noticable difference even when using 1080p. I think it makes a difference when a you play games regularly. phone doesnt get too hot and that does affect the battery life.
[Nexus 6P General] apollo3x:
Weirdly I tired this out. My resolutions did lower but then my screen shots are zoomed and don't cover entire screen.

I checked CPUZ app and it says screen size is 4.3in.

Any help is appreciated. Thanks
[Nexus 6P General] Will008:
Did you change ur dpi?
[Nexus 6P General] apollo3x:
Yes i did
[Nexus 6P General] Will008:
I'm not sure what's wrong but when I did that on my Nexus 6p the only zoomed in situations were the recents panel and the pictures of articles in Google feed when you swipe left (not in the Google app though.

I would return it to stock then try again. You don't have to reboot, first time I tried it I lost the settings after the reboot.
[Nexus 6P General] apollo3x:
I did restart and it didn't loose any settings. Resolution was 1080p.

Oh I did this on resurrection remix pie rom.

This needs to be done on stock only or something?
[Nexus 6P General] tech_head:
This is not true.

If you set the resolution to 1080, you now need to have the CPU/GPU scale the picture for the pixels.

You didn't change the resolution of the display. Think of it like this, if you display a 1440 picture the frame buffer gets filled natively; with a 1080 picture you need to scale.

There is no free lunch.

Not worth the hassle. GO look at the LG G3 forums.

Been there, done that.
[Nexus 6P General] khoacao96:
How about changing DPI? It's different right?
[Nexus 6P General] Chord_Hugo87:
so you telling me its harder to downscale the screen to 1080p then to generate images 1440p?

so consider this....playing games on a laptop is it better to downscale to 1080p or play at native 4k on a an old desktop with an older GPU.

I dont care what you say but my phone has been running a lot cooler. does it save battery? maybe maybe not but I know for a fact my phone doesnt work as hard as before because my phone isnt as hot as before.
[Nexus 6P General] Chord_Hugo87:
1.did you enable debugging?

2. did you type in the right command?

3. why the hell do you own a nexus and not root your phone?
[Nexus 6P General] tech_head:
No, what I'm saying is that the savings are marginal and not worth the effort.
[Nexus 6P General] Chord_Hugo87:
seriously? what effort? I can do this under a minute...literally its copy and paste into a command prompt and press enter and reboot the phone...giving the fact that you already have ADB install, which if you root your phone u should have ADB already.

anyway I'm not pressuring anyone to do this, just giving my result from it, and for battery I am getting better then what I used to get but YMMV
[Nexus 6P General] copong:
That's not how it works. System renders directly at the target resolution.

Even if this helped with battery life, the screen would look blurry not at its native resolution. What's the point of getting a good phone to then cripple it?
[Nexus 6P General] Chord_Hugo87:
funny

does that look blurry?

how are you crippling it? whats the point of having 1440p if you cant distinguish the difference?
[Nexus 6P General] dubazar:
Thanks for the tip, it works. I will now test if my battery life is longer.

EDIT: don't forget to type the command "su" in terminal before in order to ask root access. After this, you can type the other commands mentionned in the OP.

because it doesnt?
[Nexus 6P General] Hrithan2020:
That's interesting, if true. I haven't checked in LG G3 forums, but read some reports claiming increased performance (at least CPU/GPU benchmarks). For e.g. here

Take the case of Sony Xperia Z Prime which is able to have almost similar battery life as Sony Xperia Z despite 4k resolution and only a slightly larger battery (because it only displays 4k in a handful of apps) by downscaling from 4k to 1080p for most of the apps.
[Nexus 6P General] vaesat:
Ok i have tested for myself. You need root to make it happen. Finally I get a decent SOT of 10℅ battery drop per hour of SOT. And not 20℅ as I was getting. Everything is scaled properly except one of the keyboards that I use.
[Nexus 6P General] TonzaTheChosenOne:
This was a hot topic (see what I did there :P) on LG G3 side, people claimed to have "huge" improvement in battery life, which doesn't make any sense as you are still lighting up every single pixel. There is a article about it made by PhoneArena.

So if it doesn't really increase the batterylife, and my phone seems pretty snappy already, what would be the point of doing this? My 6P is warm pretty rarely.

Don't know about you guys, but I can see the difference between 1080p and 1440p when I'm watching stuff on Youtube, altough it could just be the bitrate increase.
[Nexus 6P General] vaesat:
I am always very agnostic with battery life and SOT. Have tried kernels with not much success. This is the first time it's working for me. I used to get 20% battery drain per hour SOT and now only 10%.
[Nexus 6P General] guta12:

Can you explain a little more? Me noob
[Nexus 6P General] Chord_Hugo87:
...no you cant... impossible to see from a screen that small, unless you are viewing with a magnifying glass...this has been proven in numerous test from TV's to Mobile phone.

but do what you want, your phone, your money if it make you feel better that you got trick into marketing gimmicks then by all means "you can see the difference between 1080p and 1440p on a 5.7in screen" .
[Nexus 6P General] TonzaTheChosenOne:
Next time you try to act all-knowing god, please read the sentence fully before trying to force your "knowledge" into people. I can see the difference, but it COULD be because of the higher bitrate, not necessarily the resolution.
[Nexus 6P General] android4life92:
But it does. 1080p doesn't look as good as 2k. Can tell straight away
[Nexus 6P General] gregb882:
Chord_Hugo67 - Don't forget, no good deed goes unpunished! Thanks for the effort.
[Nexus 6P General] Chord_Hugo87:
How am I acting like an all knowing god? Its pretty common sense, if thats the case then everyone that have commonsense is a god. Bitrate is calculated with resolution as part of the formula, since we already rule 1440p on a 5.7 in screen is a marketing gimmicks then the extra bitrate that comes with it is pretty much useless. That's just common sense to me... I am by no means a video editor but just a quick google, you can definitely see resolution and bitrate goes together.
