Hi all, I have been thinking lately about moving to WQHD resolution instead of the FHD that I'm already on. Can someone please share the battery impact and the actual screen sharpness? I have always maintained that the smaller the screen the more difficult it is to discern the actual difference between FHD and WQHD. Surely, the difference is day and night on larger screen sizes i.e. 50 inches and above. Is it really the case on our screens too? I'm on adaptive refresh rate and plan to keep it as is.

Not much of a difference in battery , may be like 30 mins of less SOT.
Gpu takes a bit of more load , and thus the overall graphics might be like 5-10% slow .
Thats my opinion, might be different for others
The difference is nearly imperceptible, wouldn't worry too much about both WQHD+ and adaptive refresh rate
Buying a phone at this price but not using the highest possible resolution is quite useless
why cant you just TRY IT YOURSELF?

Hi.
I tried both WQHD+ and FHD+ with adaptive refresh rate on for a few days each - but I couldn't discern any significant differnce in battery life with day to day usage. I'm not saying there wasn't any... common sense dictates that there must be some, but I wansn't able to appreciate it.
I was very hard pressed to tell the differnce between the two resolutions on my screen as well. When I went down to HD+, I could immediately detect the drop in quality. But between FHD and WQHD I couldn't tell initially. Over time, i leatnt to discern the differnce up close (really close) becasue I knew what to look for - but the difference was not very big. So I tested it out on my family members, and not a single person could tell the difference with confidence (none are tech nerds) - all they said is "Wow! nice screen, what do you want me to look for? Looks the same as before..."
But this was all done in the first 2 weeks since I bought the phone, so usage was erratic and frenzied. I hadn't settled into a regular routine with the phone, it being all new and shiny - installing and uninstalling new apps, tinkering around etc - so i don't think I can honestly testify as to the battery life difference between FHD and WQHD.
But I can definitely tell that my eyes found it very difficult to tell the difference in quality, even today. So I just kept it on FHD+ and forgot about it till I came across your post. Maybe it's time to try out the experiment again with a more settled down phone... as I sit here typing this on WQHD resolution, trying to imagine if the FHD+ looked any different 15 minutes ago.

I tried it and didn't see much difference so keeping it at wqhd and adaptive.
Same with 4g and 5g in my area.
Everything is on adaptive. 5g and wqhd.
Go on and use it. That's why you paid for the phone, if you don't use the feature s what's the point?
Just use the best possible resolution. No point getting a phone like this and turn things off is how i look at it.
70% of the time, on my phone: I'm just messaging/calling or using the browser to view text-based content with a few images here and there.
30% of the time: HD Video, photos, camera, video-calls, etc.
So, I do this:
(1) Remove Animations (under Accessibility or just use Finder/search to locate it) -- because I don't need
(2) Force Dark in Developer Options (goes away after a reboot, so just reactivate this).
(3) Keep the phone in 720p60fps, full-temperature Comfort Shield, Power Saving mode, AOD off, Limit CPU to 70%, Decrease brightness by 10%, etc.
(4) Use a Bixby Routine to go into and come out of this low-quality mode as desired.
(5) I have all deviceidle and other power saving settings turned off.

Now your phone will always stay dark on reboot. You're welcome.

I have seen pretty many ROMs here, but am unable to make out which ROM is best optimized keeping battery life in mind. Could anyone please help suggest me a ROM or two that give the most of the battery life. Please.
You could take any ROM that will work with a kernel supporting OC/UV (like Setiron's) and use Xan's voltage app to limit the top speed of the CPU to something less than stock (1ghz is stock, your choices would be 800, 400, 200, 100)
Then apply an undervolt as low as you can go while still being stable.
This will of course result in a slower device, but that's the tradeoff. Less speed for more battery life.
Do note that the screen is the largest user of power by far and thus you can make the most difference by keeping the backlight as low as tolerable and shut it off whenever you aren't actively using it.

Thanks Da_G. I did use SetCPU, and set the speed to 800, but for some reason it is giving me lower battery life compared to without SetCPU. So took it out.
Also, I have my screen brightness turned all the way down with auto set to off.
I meant to ask for a ROM that has all the battery hogging stuff in it removed/optimized.
I am currently like 45% left after about 8 hours with moderate usage. Trying to see if I can stretch more than this.
My today's usage statistics:
1. 11 hours 25 min 4 secs since unplugged
2. Battery remaining: 63%
3. Voice calls: 1h 10m 15s
4. Display: 1h 15m 42s
5. 2 gmail accounts with push turned on with about 10 mails delivered today
6. google voice with push all time with about 100-120 messages delivered using push
a. I do not have SetCPU.
b. I have my brightness set to 0, with auto-brightness turned off.
c. I used SamServMode to turn on EDGE, and 3G turned off since the phone was off charging hook. In short, on EDGE all the time.
d. Static but nice, colored wall paper.
Could anyone suggest me if this is good enough. And any ROM that could get me battery atleast on par with what I am getting.
A few of my ideas:
1. Use a dark colored theme. Our nice SUPER AMOLED screens don't use up much power to draw black - so the more black - the merrier.
2. Be careful of what extra apps running. Things like widget locker are one more app to run. Go slender. Theme's are okay if they replace files like frameworkres.apk but if they run in background (see it under processes) then that's bad.
3. Be extra careful of making sure you are fully charged when you flash. This means, charge, turn off, charge, turn on, charge, flash. I get a little more charge when I go back to eclair stock .
also note that 95% of battery is the screen
Everything else that was said before me was spot on so try that too.

Thank you kind sir. I shall do this. But I am not flashing anymore.
I loaded the AOSP ROM from Spaceman here

Thanks a bunch everyone who helped me on this.
Hey guys
Recently just got a optimus black and started playing games more, before i had a HTC dream and Magic was able to get 2 days of battery but atm, I'm getting like 4 hours battery playing **** what are the best settings on nova to get the most battery.
---------- Post added at 11:28 AM ---------- Previous post was at 11:21 AM ----------
+ are there any apps that really help?, using juice defender just with the balanced setting any advanced settings that improve this?
Mainly 2 things consume battery:
a) CPU ~ 15%
b) Screen ~ 80%
For a) you can decrease it by using a good governor for battery, ex: InteractiveX.
For b) it's a matter of having it on the lowest possible brightness you can handle. *
* For example, automatic brightness indoors (low) != minimum brightness, it actually consumes twice the power. Twice.

Thanks for the reply, yeah don't really change brightness so i will do that from now on, also auto uv and underclocking i am going to have a play around with.
Our SoC is already underclocked with SmartReflex.
Further UV won't do much difference.
Oh to easy then.
I bought this phone bcoz of LG advertisment :"NOVA Display automatically adjusts its brightness sensing the amount of light needed, and saves 50% energy under regular settings." (compared to regular LCD). What is the selling point for tat? LG Optimus Black eating battery damn horrible. We like LG Optimus Black including the super-bright NOVA display (LG so proud of it), then why should i need to adjust the bright to lower to save my battery? What's the point???
The point is:
- If you want the brightest screen, and to use a lot the phone with the screen on, it will drain your battery a lot.
Regards.
With CM it's possible to calibrate the auto-brightness values.
I'll try to come up with a good configuration.
Many reviewers say that they can't get the 1200 nits advertised brightness. I'm fairly certain that the note 8's display is limited by power consumption limits for whatever reason. However if you use any app that supports the video enhancer the display looks to me to be 2x the brightness. I assume samsung did this to increase the battery life. I want to know if there is a way to always run the screen in its maximum brightness mode? Maybe we could develop an app that always runs the display in its maximum brightness.
I would like to force the phone to use video enhancer in all apps including the full ui.the demo units in the store are somehow overiding the screen max brightness and they stay on the full 1200 nits the entire time.ive comapred retail note 8s with auto brighness turned off and set to optimised and the brightness on full.the demo units are brighter on max brightness than retail units.its like the demo units are somehow forcing the screens to full brightness potential but all the time and thatswithout auto turned on.and to get that type of brightness on the retail units you can use video enhance but that only works for yt and another app i cant remeber.
But the demo note 8 phones are brighter than retail handsets on full brighness
I think this would be bad for the screen with time, not to speak about batt wear
Greetings all,
The phone doesn't run 120fps all the time like for instance during the usage of google chrome, etc. You can check this by heading over to https://www.testufo.com/
On my OnePlus 7 Pro, we can enable constant 90fps via adb.
Was wondering if anyone has figured out a way to get get it working on our Rog Phone 2 ?
Cheers.
Won't this drain the battery?

No it doesn't, no noticeable drain on the OnePlus 7 pro.
Is it because the phone has variable framerate to save battery? Or because the display isn't capable of keeping 120hz?
Yes the same here.. Only after switching on the 120 hz in the topbar menu I have 120 hz also in the browser. I hope they will fix this.

Guess its a bug because when you activate it from the quick settings you get 120 fps all around. On my oneplus 7 pro, by default , on chrome and other apps it switches back to 60fps too but you can activate system wide 90fps via adb

yea, hope they get it fixed soon, sometimes after reboot it goes back to 60 or when you open and close the app. Whats the use of having 120fps if you only get to use it on the homescreen and asus's stock browser lol.
Hi, I'm thinking of getting the Asus rog 2 ultimate edition when it becomes available soon. And I would like to know if the 120 hz force mode could be activated like one plus 7 pro.
Since I had the oneplus 7 pro I had the 90hz force mode and I can't use any device without feeling the choppy effects of the 60hz. Be it iPhone or note 10 plus. And I hope someone has managed to find a way to activate 120hz ask the time.
I think it is a bug of Chrome Stable.
You can use 120hz continuously with Chrome Beta and Dev version.
You can choose, via settings, the screen mode: 60Hz, 90Hz, 120Hz. If you have 60Hz (default choice), of course the browser will run at 60Hz, no wonder about that. And, of course, the screen will drain less battery.
From the settings, you can choose to run ALWAYS at 120Hz. In some BATTERY test, tho, they showed how 120Hz ALWAYS will drain more battery. So, they suggested to use 120Hz mode only with X-Mode, so you can use it for games.
But, if you wanna use it ALWAYS, so even when you surf on the web via browser, you can activate 120Hz mode from Video Settings, in order to be Always on 120Hz.
Sorry for the noob-ish question, but is there any significant difference between a 90hz panel and a 120hz panel? I know that it's a leap from a 60hz to a 90hz panel, just wanted to know if there was any noticeable difference between the 90hz and 120hz.

Not much difference, but if I am going to keep it on 90hz then what is the point of getting the device over the ROG or 1+7. Also the battery saving isn't much you will probably get 30 mins ~ 1 H SOT vs a 60hrz constant refresh rate if I recall correctly. Any way it comes down to the type of device usage.
I will advise to try different settings and stick with the one that suites you. Personally I like to keep it at 120hz unless I am short on battery.

Plenty. Heck, I'd take this at 60Hz vs the 1+7 (or most any phone, for that matter), because there's plenty to love about the phone. Aside from the lack of U.S. support, of course...
Hello there
I'm having an issue getting around 3hrs only of screen time, and after monitoring the device for several days I noticed that the refresh rate is stuck at 120hz even if I'm on the home screen not touching the phone
After changing the refresh rate to 60hz the battery performance is now excellent i'm getting around 8 to 10 hrs
So the problem for me was that the software was not handling the refresh rate right and even while using the phone with 60hz it never drops to 1 or 5hz
It's STUCK to either 120hz or 60hz
Any suggestions about fixing this issue?
It suppose to have an adaptive LTPO2 screen...

Yes i agree with you, that is the same problem with me, I just noticed it stays on 120hz every single time. THAT'S WEIRD.
Thanks for letting me know, unfotunately, i have no solutions for it, I will be waiting for someone to find a method to fix it.
I think it can be resolved with a minor system update, it's all about this post reaching someone inside OnePlus.
Until then you should lower the refresh rate to 60hz in order to save the battery health "wear cycles".

Unfortunately it requires the phone to be rooted
I tried the 120hz now under sunlight and noticed that above 80% of the brightness the refresh rate drops to 1hz while reading, above 50% and below 80% it drops to 10hz, and below 50% of the brightness it is stuck to the 120hz
I think if an update came to fix the refresh rate under 50% brightness the battery life would be great.
