I might be wrong, but I would agree that in most cases, there is no real battery hit.

Just one case, there is this game "The House of DaVinci", a game like "The Room" series. It really benefits from the mod, the game is so smooth (for other games, there is no noticeable difference), but the phone does get hot and the battery goes down visibly faster.

It's probably a rare occurence, because obviously not many people play that particular game, but there it is.

It does look a lot better though ingame!
[Xiaomi Mi 9 Themes, Apps, and Mods] duvee:
Wait, sow the only benefit from it, is in games? Or am i missing something? I thought system animations for example would be more smooth..

Edit: i guess you only gave an example :p
[Xiaomi Mi 9 Themes, Apps, and Mods] kipue:
Yes, all is smoother, sorry, I focused on the impact on the battery!

I meant it does not impact the battery *really* unless specific cases :)

Hope that's clearer

Can anyone give a 60hz IMG?

I forgot to do a backup...........uhhh
[Xiaomi Mi 9 Themes, Apps, and Mods] invd:
Here is my TWRP backup

After some reading in this thread I finally tried this mod and I'm quiet impressed with the smoothness. Aside from visual glitches like green tint (which is not present for me) - could there be any long term problems for the display? Does anybody - with more technical knowledge than me - here could take an educated guess?
[Xiaomi Mi 9 Themes, Apps, and Mods] Qidamin:
What surprised me is the official answer from Xiaomi’s director of software, Zhang Guoquan, to this mod. Of course he said that the mod can cause issue, but he was pleased to see that the community was working on the Mi 9, and didn't say anything like avoid this mod at all (if I am not wrong). Maybe it means that the screen can effectively work this way?
[Xiaomi Mi 9 Themes, Apps, and Mods] zoltan78:
I try to flash this on xiaomi.eu 9.6.27 and does not work, stil 60Hz
[Xiaomi Mi 9 Themes, Apps, and Mods] pokko:
Did the App say DONE after update.

Otherwise try a different file explorer to select den dtbo.img
[Xiaomi Mi 9 Themes, Apps, and Mods] zoltan78:
Yes I have information Done.

But no changes.

[Xiaomi Mi 9 Themes, Apps, and Mods] Qidamin:
Just installed it! The phone seems much snappier! I think I have noticed a green tint at first but after a few seconds I have already got used to it. Really not a deal breaker for me.
[Xiaomi Mi 9 Themes, Apps, and Mods] HTCDevil:
Can you link please? :)
[Xiaomi Mi 9 Themes, Apps, and Mods] Nuno Oliveira:
Maybe he just wants everyone to crash and burn the screen and to go buy next gen phone...

Or not, who knows [emoji28]

Just kidding, just waiting for long term feedback on this mod to try it on.
[Xiaomi Mi 9 Themes, Apps, and Mods] Qidamin:
https://en.xiaomitoday.it/xiaomi-mi-9-84hz-80hz.html

I got scared at one moment with a kind of wallpaper I use. In the multitask window the background should be blurred but one part on top and on the bottom was just a black area, as if the pixels were dead. It didn't appear like this in 60Hz. But I don't think the screen has any damage, still displaying everything fine so it's probably just an issue with this wallpaper.

I also feel the brightness is higher in 84Hz in auto, should be nice for me to have it decreased a bit.
[Xiaomi Mi 9 Themes, Apps, and Mods] qbaqi9300:
[MENTION=6888352]Qidamin[/MENTION] I think it is not a problem with the wallpaper but with the frequency of the display. It should be reduced to ~ 75Hz

Overall the modification is great, but it should be improved. Frequency level at 84Hz without complete modification of the source code causes other problems with displaying good image quality.
[Xiaomi Mi 9 Themes, Apps, and Mods] Khotu:
It would be nice if someone want undeclock for example for 50Hz for better battery and display life :)
[Xiaomi Mi 9 Themes, Apps, and Mods] csakesz55:
you got an answer for that previously, that's a bad idea. Also, if you would've read back, it's been stated that it's not being developed by an XDA user (afaik), so asking here is pointless I think.
[Xiaomi Mi 9 Themes, Apps, and Mods] arddy1:
It wont be nice.

Scrolling text would be pain for eyes, cant play 60fps video, and the screen would look like a cheap tft display phone.

Would be a shame doing that for a flagship device.
[Xiaomi Mi 9 Themes, Apps, and Mods] ggkameleon:
Do you think work on mi 8 ? Or can you make port for it please :)

Thanks
[Xiaomi Mi 9 Themes, Apps, and Mods] Qidamin:
There are no problems with image quality. Only issue for me is that the brightness is a bit high and it decreases the contrast. That was the issue with this wallpaper in the multitask window (which is not really an issue). Other than that, I have played games during one hour under 35 degrees outside without any sign of heating or anything.

To be polite, it is getting annoying people asking for this mod for another device every two responses. If I am not wrong the mod already exist for Mi8...
[Xiaomi Mi 9 Themes, Apps, and Mods] malbert16442:
This is quite an enjoyable mod. No visible side effects on a global device. Display tends to display more natural colors however which I prefer. It turns out any overlays over the screen may produce some tints so please check your apps. I found this out using the app dimly to reduce screen nits. No other issues. I would like to find a way to reduce this mod to 78 or 80 as display prefers this hz.
[Xiaomi Mi 9 Themes, Apps, and Mods] kickassdave:
What an awesome mod.

Getting 82Hz and the added smoothness is an absolute joy

Thank you!

I did also notice a slight change in colour tone, but honestly... really not enough to bother me. This one is a sticker for me and I'll be applying it to all ROMs in future.
[Xiaomi Mi 9 Themes, Apps, and Mods] EZY-E:
Is this possible for Mix 2? :o

I would gladly donate money for this tweak.
[Xiaomi Mi 9 Themes, Apps, and Mods] sonicxd64:
I was afraid of trying this but omg this is awesome!
[Xiaomi Mi 9 Themes, Apps, and Mods] ggkameleon:
yes I understand and thank you for your answer by remaining polite.

I think if they had much demand for other devices it is that the mod you have developed (great job & good idea) is so good that everyone wants it.

It's just the beginning and if it works well in long time you risk being overwhelmed with demand.

I have search before on mi 8 thread but don't see same mod and search with Google too but only see for mi 9.

Thanks I search it again later.. Have a good day.
[Xiaomi Mi 9 Themes, Apps, and Mods] kickassdave:
I think this question is being asked far too many times already.

The developer of the mod is Chinese. Ask there.

This is the Mi9 forum and these questions waste space here as nobody will do anything about it.

I think the OP should add a note advising this to the first post....
[Xiaomi Mi 9 Themes, Apps, and Mods] Harrison8c:
their website doesn't load me the input verification text for some reason lol
[Xiaomi Mi 9 Themes, Apps, and Mods] duvee:
Come on guys.. Pls use the brains and go to the xda section of your own phone. It is really ridiculous to ask those type of questions, while every question is allready answered!

I follow this thread, and i dont like all the golddiggers trying their luck in the wrong section of the forum..

Mods?
[Xiaomi Mi 9 Themes, Apps, and Mods] iEstuardo:
Wow that smoothness! It's awesome.
[Xiaomi Mi 9 Themes, Apps, and Mods] t-r-e:
I applied the mod and it looks awesome !

I'm on xiaomi.eu 9.7.4

I had a green tint , played a little with color calibration in settings and i kinda fixed it (still visible on lock screen)

Power consumption also took a hit , 5 hours down from 7 hours screen on time

Even with all of this , I can't go back , smoothness spoiled me

My question is why ufotest shows only 79 fps ? Not all screens created equal or what ?
[Xiaomi Mi 9 Themes, Apps, and Mods] Schnedi:
I know it's not for Mi 9T but i wanted to try. Booted to fastboot.

Flashed the original dbto.img and booted to system.
[Xiaomi Mi 9 Themes, Apps, and Mods] Xhiantes:
The mod's very awesome but it's damaging battery. I'm using this mod from 2 weeks and my Phone is heating and battery life is lowering.

But really smooth and speedly.
[Xiaomi Mi 9 Themes, Apps, and Mods] Perfectdevil:
So it's worth it
[Xiaomi Mi 9 Themes, Apps, and Mods] PriPhaze:
Phone doesn't heat just with this mod.

That's probably you using the phone while it's charging or running heavy apps.

I have been using this mod lately and yesterday I went to work with 95% battery at 9am and arrived home with 75% battery remaining and 1hr 23mins SoT at 9pm. That's 12hrs and just went down 20%.

I even have the 810mhz GPU OC running all the time.
[Xiaomi Mi 9 Themes, Apps, and Mods] Hi1307:
Lanthanum crashes when I try to flash the modified dtbo.img
[Xiaomi Mi 9 Themes, Apps, and Mods] SafiZaf:
As a telecommunications and computer engineer my educated guess is this one. When parts are bought they have operation values, in the case of the screen it should be 1 to x fps. The mi 9 screen has a nominal value of 60 hz, this means that the screen was built for mainly 60 hz and at 60 hz it shows the failure rates accepted by xiaomi for this phone. Depending on the grade fail rates as an example can be 1 flaw in 100 000 devices with screens operating at 60 hz. The higher the refresh rate goes the bigger the stress generated in the parts increasing the fail rate to 1 flawed in 70 000 and so on. The values I gave are examples and are not the fail values for that part. In conclusion, the higher higher refresh rate like 84 hz can make your screen more susceptible to fails such as color shifts, artifacts, dead pixels etc. Remember the more stress the more failure chance you get. I hope I could help. :fingers-crossed:
[Xiaomi Mi 9 Themes, Apps, and Mods] EspHack2:
ive been overclocking displays since radeon was ATI, generally speaking, running your stuff harder will decrease its lifespan, by how much we can only try to guess, but no it wont blow up because of it, most screens will simply refuse to run if the parameters are out of its capabilities, and they differ from unit to unit, if its a specially crappy display then it probably will artifact like crazy instead of refusing to run and that can damage it, but you wont leave it running like that for a year i guess?

overclocking a screen often means losing color quality and/or resolution if there isnt enough bandwidth, also it can make faults more visible, like horizontal lines going up-down, discoloration, etc

so far ive never broken a screen by doing it, and it seems to me the smaller the screen the higher quality it is, laptops often do 90hz, my surface go did 110hz! but i kept it at 90 for battery, ofc ymmv
[Xiaomi Mi 9 Themes, Apps, and Mods] rpgraffi:
this greenish tone is just because of the Anti Flackering Feature. Turn it Off ant it will work right
[Xiaomi Mi 9 Themes, Apps, and Mods] *justintime*:
For me it did not help... On or off... The colors are strange especially when it's dimmed. The blacks are distorted.
[Xiaomi Mi 9 Themes, Apps, and Mods] t-r-e:
i have the same issue here , dark colors specially black are distorted in some situations (like when watching movies and some app previews in recent apps , the colors feel like they are crushed) and in other times they are just fine , but the strange things is that when i reverted to 60hz dtbo img , they stayed that way , so i thought maybe i'm just imagining things , maybe they were like this before but i'm being nitpicking after i flashed the mod ! untill i hear from you that i'm not the only one here !
[Xiaomi Mi 9 Themes, Apps, and Mods] Inkku:
+1 on the weird crushed blacks. I noticed that on low screen brightness dark grey like on the xda app tints strongly into green. Also I've been getting a double tapping issue, or even triple tapping sometimes? Like sometimes when I tap, the phone registers it as a double or a triple tap. It gets super annoying, especially when typing.
[Xiaomi Mi 9 Themes, Apps, and Mods] Dor71:
The black color is distorted for me.
[Xiaomi Mi 9 Themes, Apps, and Mods] Mohammed779:
Been using this mod since day 1, and going back to 60hz feels like a big no at this point. Colors are good with some calibration. I'm on LOS, and it's definitely better used there than MIUI. Color distortions are almost not existent.
[Xiaomi Mi 9 Themes, Apps, and Mods] hellsoft:
I tried to go back to 60hz twice and no chance - Since you get used to 80hz you can't go back.

More - after using this mod I will never buy a phone without 90hz or more.

I can barely notice that colour distortion, I'm on 50% brightness + Reading mode on + small colour calibration.
[Xiaomi Mi 9 Themes, Apps, and Mods] saleemz:
I've successfully installed it by fastboot command "fastboot flash dtbo dtbo.img"
[Xiaomi Mi 9 Themes, Apps, and Mods] Dark Messiah:
With the app "screen balance" I think I could get rid of the green tint, it adjusts the colors with just one click with an overlay ( https://play.google.com/store/apps/details?id=co.uk.quickdoc.screenbalance&hl=de )
[Xiaomi Mi 9 Themes, Apps, and Mods] qbaqi9300:
I'm still waiting for a better mod without distorted colors - any of apps from Google Store does not fully fix the problem.
[Xiaomi Mi 9 Themes, Apps, and Mods] Krazhil:
This mod is the only reason I unlocked and rooted my device. After some struggle it was really worth it.

I would have never expected this mod to be so nice, although I have already experienced 90Hz and 120Hz displays.

There is definitely a greenish (and some blue) tint on the screen. After reading the comments I was a bit afraid of applying the mod, but the greenish tint can be "fixed" with the build-in color adjustment tool (see the attached screenshot).

Of course you can chose that color which pleases your eyes the most and you can also boost the colors by selecting "higher contrast".

Even though the colors are not at the level of e.g. a Samsung Galaxy S10, you should keep in mind the price of this phone and the possibility to do this mod.

I have the Global Xiaomi Mi 9.

Can this mode be tried on xiaomi 9t?

Thanks

If you can't use the app, just flash the img in twrp to dtbo. Or use "fastboot flash dtbo dtbo.img". Never used the app in OP.
[Xiaomi Mi 9 Themes, Apps, and Mods] hellsoft:
Is there any other/newer dtbo.img file to download? If so please share the link. Thanks

How 's the battery affected by this mod?

Is there a way to format dtbo partion and do a clean flash to regular 60hz dtbo image ?

I'm experiencing a wired crushed dark colors (noticed on low brightness and when watching movies "like there is something wrong with color gradient")

The problem still presist even after reverting to 60hz ..my thought is that flashing the 84hz img missed with something on dtbo partion , so is there a way to format dtbo partion ?
[Xiaomi Mi 9 Themes, Apps, and Mods] bornlivedie:
what do you mean by crushed dark colors?

if you mean the purple tint/ghosting when scrolling, that's normal and happens on all AMOLED screens in the whole universe
[Xiaomi Mi 9 Themes, Apps, and Mods] t-r-e:
no , like there is something wrong with gradient in dark colors ( 8 bit like effect in grading)

see the attached picture to see what i mean
[Xiaomi Mi 9 Themes, Apps, and Mods] Daenjel:
+1

I've also seen this, just after going back from 84Hz to 60Hz, I thought it was normal but now looks like its an issue caused by the mod itself
[Xiaomi Mi 9 Themes, Apps, and Mods] omgomg:
Anyone else having issues with the fingerprint sensor with this mod? It just doesn't recognize my fingers anymore.
[Xiaomi Mi 9 Themes, Apps, and Mods] catalindobre:
dirty flash again the ROM on top of actual one, and you should be fine.
[Xiaomi Mi 9 Themes, Apps, and Mods] syndicate333:
Would it be possible to backup dtbo via ADB? If yes, how? Thanks!
[Xiaomi Mi 9 Themes, Apps, and Mods] johnslash:
I do have some fingerprints issues when using auto brightness on a really dark area. You just have to increase the brightness and it should work, it should also work when unlocking via the always on display.
[Xiaomi Mi 9 Themes, Apps, and Mods] DiGiTaT:
I just switched back to 60 Hz. Damn..., it's really lagy and not smooth.

> I can't go back to 60 Hz. I hope the screen won't damage with that mod.
[Xiaomi Mi 9 Themes, Apps, and Mods] MickyZa:
I ordered my mi 9, so what is your opinion guys, should i try this mode or no when phone arrive.
[Xiaomi Mi 9 Themes, Apps, and Mods] Krazhil:
tl;dr:

+ Much smoother

+ Less touch-delay

- Colors (initially green tint which you can drown out in the MIUI options, so you won't notice it that much)

- You don't want to use a phone with 60Hz ever again

From my experience I can tell you the following:

Before I used this mod the Mi 9 was for me already the smoothest experience I have ever had. After flashing I immediately noticed the difference. The animations and reaction when touching the screen was noticeably better. I tried to go back several times, but I just can't. When going back I feel the latency/delay and that the animations are not THAT smooth. It's about the same experience as with the iPad Pros.

The only downside I've noticed so far is the colors. Even after adjusting the colors in the display settings the colors are not that strong, even when using the "higher contrast" option.

I think the problem with the colors can be fixed if there were a calibration tool, where you can adjust at least every color. With the current option you can only "increase" the other colors. So the green is still present, i.e. the contrast and colors are not so punchy.

I remember from my Nexus S or Nexus 4 (I don't remember which of these) that there was a really powerful calibration tool, where, with an appropriate kernel, you could calibration every aspect of the display colors.

Edit: You won't notice the color difference on high display brightness. If you do this mod, i would suggest you to go into a shop where they have e.g. a Samsung Galaxy S10 (= known for best displays). Go to the Samsung Options->Display menu, chose a "neutral" color profile (deactive the PUNCHYYYYY demo colors if active), and try to match your Mi 9 display colors to Galaxy S10's.
[Xiaomi Mi 9 Themes, Apps, and Mods] Daenjel:
We can adjust all that using Kcal over a custom kernel and use some app to edit the color parameters and saturation (Like FK Kernel Manager), but sadly, we don't have any kernel developers working on this device right now, we could start a fundraiser to donate a Mi 9 to a great developer like Francisco Franco or Arter97, but dunno, this community doesn't seem interested on all the benefits that comes with custom kernels and that stuff..
[Xiaomi Mi 9 Themes, Apps, and Mods] Daenjel:
It's just from what I've been asking to others here in xda and over other forums as well, I'm not saying that this is a fact, that's why I used the words "doesn't seem interested" but, if I'm wrong, then we should start it, why not?
[Xiaomi Mi 9 Themes, Apps, and Mods] bhazard451:
In order to hit 84hz, we are probably decreasing color gamut. I much prefer 84hz over 60hz though.
[Xiaomi Mi 9 Themes, Apps, and Mods] MickyZa:
Thats great, but i seen many people here switching back to 60hz. So i was doubtful about this rom. And one more question, when you switched back to 60hz you said you feel latency, is that caused by mod or it just doesn't feel smooth anymore after trying this mod?(sorry for my shi*y grammar)
[Xiaomi Mi 9 Themes, Apps, and Mods] Krazhil:
It is because I am used to 84Hz now. I also did 2 complete wipes of the phone and still noticed a difference before I flashed this mod ater wipe.

Btw.: Unlocking my device and flashing Xiaomi.EU Rom broke my GPay (I tried lot of possible solutions, but didn't help), so I can not pay with NFC anymore.
[Xiaomi Mi 9 Themes, Apps, and Mods] Sammy1221:

[Xiaomi Mi 9 Themes, Apps, and Mods] mongoload:
Using this for 2 days and it has been great! Scrolling is so smooth, it can be compared side to side with other phones and you will see the difference!

Only issue is the slight greenish tint on grey color when the brightness is set to low.

My only concern is the longevity of the screen. Does someone find the model # of our screen?

Thanks for OP on this mod! Reading tech news about our device always put a smile on my face. It was such an excitement to try this mod and it really delivers!

I made a backup using TWRP and flashed the .img file in TWRP as well.
