[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.

NOMone resolution changer in the app store lets you bring it down to 1080P.

[Q] Is it possible to overclock the s4 screen refresh rate ?

Hi, I know that super AMOLED screens have a really short response time and so I'm sure we can go easly to 144Hz and more, but how can we get that ? Does just an app with root privileges can do that ? Or a custom kernel ? Or it is just impossible ?
Thank you for helping

I don't think there is. There is not much to be found on google about the subject. I also don't think the phone would be able to reach that 144 fps. Android phones have some kind of vertical sync which limits fps to refresh rate.
You can disable that fps limiter, but doing so creates visual artifacts.
Also, I did disable mine once and in quadrant's fps counter the fps never got above 110 fps..

Huawei Mate 8 [3 days] Mini Review (+ Nova Launcher)

Hi there,
You can call me Eme, and I am here to share my knowledge as a tech-oriented engineer. I am humbled to be one of the first to own a Mate 8 (UAE) after a long wait from Hong Kong.
My findings are reflected on day to day performance (work + daily activities). So far what I found:
- Packaging looks gorgeous.
- The fast-charge takes a while since its a 4000mA.
- Colors are vibrant.
- Blacks are average, not as good as LG V10/iP6s+.
- Battery lasted to the second day with 35% (with extensive use like gaming, downloading, youtube, camera test).
- Speakers sound crisp, rich and loud without distortion. Louder than iPhone 6s & Samsung Note 5 (bass is much deeper).
- As for Huawei's new headset, you will notice an improved sound on DTS mode. There is no information whether or not a dedicated DAC is inside the Mate 8 (like V10/Note5). The sound is crispy clear and rich in highs, mids and lows. You can increase the functionality by activating "Smart headset control" feature to have total of 9 commands executed with just 3 buttons (volume up, volume down and mute).
- Headset design is copied from Apple's. It doubles as a radio antenna (keep it).
- The aluminum unibody is rigid.
- Antennas are excellent and signal reception is always full bars 4G (there is a signal boost feature which can increase signal intake). Haven't tested that one yet since I am in the city.
- Not on the thick-heavy side like iPhone 6s Plus.
- Lock button is clicky, just like Mx Cherry Red keyboards. Likable.
- SECURITY screams out of it. Whether it is from Marshmallow 6.0 or Huawei EMUI 4.0. The device is restricting every single bit going in or out.
- 1.93 GB is available out of 4 GB RAM as observed. After deleting Huawei bloatware RAM went up to 2.4GB.
- The Camera takes sharp photos during daylight. I have yet to test night shoots (Super Night mode).
- Camera app features: Panorama, Super Night, HDR, Professional, All-focus, Watermark, Online Translation, Slow-mo, Object Recognition, Audio note and Document readjustment.
- Launchers like Nova run smooth and fluid.
- Gaming performance, minor games with high graphics might find screen tearing & inverted colors. It may be good for average games (or top games with medium settings).
- There is a data transfer speed monitor besides the battery indicator on top (very handy).
Super Night mode:
From what I noticed so far is that you need a stand or hold the phone steadily to wait for 23 seconds in order for "Super Night" to process both high and low ISO shots then combine them into a picture. In my opinion this is not what users are looking for in a big gathering or a date. More photos will be posted later on.
Gaming:
"Kritika" example: Notice the top is Medium settings. Bottom is High settings.

Wow that game performance doesn't sound great at all. Almost unusable.

Have you set it to performance mode for gaming? GPU is ~85% of the power of S810 but only on a 1080p screen here. Emulators running fine for me here, just installing Dead Effect 2 to see how it goes. If you have performance mode on then I'd suspect it's more a matter of poor optimisation for the SoC, which unfortunately is not likely to improve a whole lot given the number of Kirin 950 devices will be small.
---------- Post added at 08:56 PM ---------- Previous post was at 08:53 PM ----------
Also, you need to give Play Store internal storage permission to download those large games, until I did that I had same issue as you with large game installs appearing to cause the Play Store to crash.
ADDIT: Tried Dead Trigger 2 on max settings and seems fine. Riptide GP2 also fine, although won't allow the highest shader setting (crashes), maxed apart from that.

The phone is gorgeous, it is my daily driver as of now
Performance mode is on when I have done the testing.. Screen tearing and stuttering are still there (Kritika on high graphics). Probably due to the fact that it is a Mali-T880 MP4 (less), not MP8 like Samsung's.
I will post a screenshot after I finish my 10 post limit restriction.

Might be that one game, just tested Asphalt 8 in addition to the above and no issues on max settings. Also, doubt it's 4 cores vs 8, given the difference in screen res here.

Some games worked fine and some didn't. All the games I tested ran smoothly in Note 5's old gpu Mali-T760MP8 on high graphics. Performance mode didn't help the in gpu department.

Just installed Kritika and played all the intro levels, no issues here.
Some games working well and not others points to lack of optimisation for the SoC, rather than indicators of the GPU performance I think. Kritika had to redownload the game assets when I left and restarted, which didn't seem like an indicator of a high quality piece of software to me (that and the game is utter freemium trash).

OP is correct tho in saying that the upcoming S7 will have the same gpu but actually with 12 core (T880-MP12) instead of the mate 8's MP4. fine by me though, i dont really game on my phones [emoji14] thats what i use my high performance laptop for

Of course, never said otherwise. It'll significantly outperform this for graphics. For native resolution workloads the difference will be far less pronounced.

very true! at perfect scaling and all other things being equal, the MP12 will be performing at 300% of the MP4 at identical resolution. considering a 2K screen will have 78% more pixels than a 1080p screen, the real world performance will be more like:
300% / 1.78 = 169%, thus "only" 69% faster than the mate 8
in any case, the mate 8 gpu will be almost twice as fast as the current setup in my nexus 5
Sent from my Nexus 5 using Tapatalk

Yeah, in absolute terms faster than my Note 4, in relative terms taking into account native resolution quite a bit faster.

I was talking about overall experience not initial impression. You won't notice that because I have played the game for a while and my character has high level armor which started tearing and changed color from dark grey to pink.. Let me upload the image to show my findings later.

where is the test photos for the camera ? we are all eager to see how it performs ?
the mega pixels says nothing.
What I expect is mediocre camera that will not handle evening photos very well like most, and it will have a lot of shadows if the light conditions is not ideal.
This is what I expect.. Nexus 6P did prove this and they killed the megapixel race... since manufactures understand now it is not about megapixels.
Appel have told us that since stone age.

This is not intended to show the true power of this device. It is basically tap and shoot. There is a Super Night mode I have yet to test. More photos incoming.

Thanks for pics, not yet shot a low with mine yet. I have a steady hand, so for static night images I would use a low ISO for reduced noise and compensate with a slower shutter speed in super night mode, but good to see point n shoot performance. Will post some of my own examples later.
Regards some games "crashing the Play Store" - you might want to update that for readers with the solution I posted later.
I still think you're still making far too much of an issue with a single game. I know you haven't tested as many other higher-end games as I have as you hadn't worked out how to install them, please post some more feedback when you have tried some of those much larger installs.

Regarding the photos in your first post.
The photos seem noisey even in daylight shots.. .
Did you install the latest firmware update which did improve the camera ?

I shouldn't be making an issue if the graphics wasn't behaving that way. If in this mid-tier game graphics can't be handled then there is probably plenty other games that will show same behaviour or even worse. It has to be tested further.
As for crashing. Thanks for reminding, It will be updated soon.

[Poll] Wqhd or Fhd?

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.

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

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.

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.

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'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

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.

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.

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.

Low resolution works only in games and some apps, not in system

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.
