Question Pixel 6 (Pro) Variable Refresh Rate - Google Pixel 6 Pro

Hey guys, looking for confirmation. I recently started exploring this phone's VRR to see if I could find a way to force max refresh of 90hz on the pro to try and save battery. Ran into trouble and found this video showing the phone only goes from 60-120hz:
I've heard arguments against being able to see the refresh rate with the developer options tool, as refresh rates of LPTO displays happen at lower (hardware) level than the "show refresh rate" tool (software) can view.
Many VRR displays use profiles rather than true "seemless" switching, ie: 1hz, 10hz, 11hz, 24hz, 30hz, 40hz, 60hz, 120hz.
Does anyone have the necessary expertise to tell me what's going on here? Do our Pixel 6/Pro displays have two refresh profiles, 60hz and 120hz, and that's it? Or is this a failure of the methodology being used in the above video's test? Further, is this a hardware limitation, or something that can be fixed via a software update in the future?
Thanks to anyone with some insight
*Edit* Here's a pic of the website "smartprix" claiming the P6P is variable down to 10hz

Here's another troubling post about the display on this thing, if anyone is interested. I'm hoping we can get some of these things addressed in updates, because I really love this phone. I just want to find a way to make the battery last a bit longer..
Are these issues that perhaps custom kernels may also address? Sorry if any of these are obvious questions, I just plan on keeping this phone a long time and hate seeing these head-scratching issues. Thanks

He also mentions in that thread that this is pretty much unfixable. I wouldn't bet on custom kernels etc being able to fix this.

It is fixable (in theory).
The hardware supports a variable refresh rate from 10-120 Hz, so in theory that can be used "fully". Meaning 10, 30, 60, 24, 90, whatever.
BUT - Google locks it down. As of now, we do not know why, or how.
Maybe someone will find/make a fix/a mod one day, maybe Google will do it.
Right now we do not have a fix, and don't know more. Not much more to say.

So, would it be better to force 120 Hz in developer options?

I don't see how, it would just cost more battery. The phone ramps up to 120hz fine, it's lower frequencies that are the issue. Which leads to yet another thing that's compounding battery problems

Is it possible to get different control with a custom ROM?

Interested to know if you've found any updates on this in the almost 2 years since you asked. Setting the max refresh rate to 90Hz would be cool!

"Force GPU Rendering" in Development options

Hi all,
Noticed the "Force GPU rendering" option under the Developer options which was off by default but is captioned "Use 2D hardware acceleration in applications". Is this advantageous to turn on? The few online resources I've found suggest it could be because it offloads all 2D graphics work onto the GPU instead of CPU. Having turned it on and played a bit I /might/ have noticed some more fluid animation, but could be a placebo effect.
Also, reckon this would have any impact on the battery life? (Desperately looking for ways to make this thing last through a day).
Thanks!
It forces all apps to use the GPU to render themselves instead of using the CPU. This is more efficient and actually does improve the fluidity of the UI. To test it out, download the Twitter App from the marketplace. Try with and without Hardware acceleration. You should notice a definite improvement. My suggestion is to keep this option on. After Apps update themselves to use GPU rendering themselves (it's only one line of XML code) this option will be pointless. The option is already pointless for Google Apps, as they should all be updated already to use GPU rendering.
Sweet. Anyone try running benchmark apps with it on? I'm trying to figure out if the SGSII hardware acceleration played any tricks on their benchmark scores (I've always wondered).
Knew I was noticing some improvement in apps, including Twitter!
I have noticed a couple of apps so far that this option breaks:
Vouchercloud (doesn't display anything on screen)
Tiny Tower (crashes during load)
So beware, if you have this on and some apps crash or display strangely, try turning it off.
I'll be keeping it on unless I need to use one of those two apps though.
Thanks for the full explanation.
Amazing tip, thanks! I loaded Twitter and noticed it was slow, then I remembered reading this thread before (read so many whilst waiting for it to be delivered) and tried it with this option turned on and it was perfectly smooth.
Cheers

That's a perfect example of why they didn't set it to default ON. If developers had actually followed the API there would be no problem but some seem to use a known side-effect of the old rendering model to skip some lines of codes for screen redraws. Google explained this in a Google IO talk.

I've noticed also shazam and radiant also break when using the 2D accel option.
Slightly annoying you can't set up a blacklist - but we'll see how quickly these get updated.
Also crashes:
Square
PicSay Pro
Shazam works for me
Perhaps I'll make a new post so that we can compile a list of apps which have trouble when Force GPR rendering is turned on.
For quadrant it seems to be give and take with the option forced on.
This is my Nexus S w/ CM ICS, GlaDOS kernel. Pics captured on 2nd run, after consecutive runs.
You can tell which had 2D hardware rendering forced by the 2D scores on the bottom.
An ongoing list is over at:

HTC 10 Refresh Rate Subpar

Has anyone else noticed that the HTC 10 is not constantly at 60hz? It's not that it drops frames, but I think software is capping the frame limit or changing the refresh rate constantly. Videos seem 60hz but on the launcher or in apps, it seems to run 48-55hz, and it kind of annoys me that my two year old Xperia Z3V feels much smoother and more premium. Anyone else want to test with testufo.com and see if this happens?

Doesn't bother me tbh. Only time I start to give a damn about frame rate is when I can see noticeable jitter.
I ran the test and it maxed out around 57 and 59.
Tested side by side with Galaxy S7 -> same thing.
58fps~60fps
The lowet value was by S7, with 52fps

The refresh rate situation is further exacerbated when viewing VR content... It's definitely not as smooth as even the SGS5. Any workarounds to get the refresh rate up??

you can try boosting the CPU by a setting in developer settings

Unless you go custom, you can't fix this because it's an overly aggressive powersaving thing from Htc.
If you're unlocked, then you can flash something to disable it and then your phone stays at 58FPS.

Tried that also. Didn't work.
Beginning to think it is a combination of the powersaving function PLUS LCD's refresh rate.
Ho hum, pretty bumped considering the power of the 10 under the hood :/
It will definitely make a killer VR device.
How did you get the graphical Back/Home/Recents navigation buttons on the bottom of the HTC 10? I don't see this as an option anywhere.

My Viper10 rom has that option, but I think this is some AOSP based rom.

Question How is That Even Possible

As you can see my phone Charges pretty fast. It Charges 0 to 100 in one hour. But charge Drains fast also like 4 and half hour screen time. Im on MIUI 13 global.

That's stock MIUI, right? It's possible you have some background stuff going on that drains the battery on a regular basis. If you haven't already, try clearing your Recents view to see if that helps.
I am using Arrow OS 12.0, myself, and ended up enabling the Developer Options selection for 'kills all activities once user leaves them'. This improved my active consumption rate from being ~8-9% per hour to ~6% per hour. You can give it a try, too!

Yes its stock. I couldnt find any app yet, im Still searching and looking for a help.
Oh, maybe you have the same issue that I had.
Check if the MIUI gallery is going crazy in the background. I have yet to figure out what caused that, but it wrecked havoc on my device.
Get something to view your CPU frequency in real time, normally all cores should idle at under 1000MHz with nothing else open in the background (I used CPU Float to check that).
If your little and/or middle cores appear to be clocked high, try to see if force closing the gallery and not reopening it helps. I fixed it for good only after having disabled its storage permission, ended up switching to google photos instead.
Hope this helps.

It looks like this and going crazy up and down all the time. I force stopped gallery and remove the permission but its Still the same.

Question Advices for a fresh user

Hi .
I'm about to get my s21 FE this week. Could you perhaps point me to the right direction and show me what are the things I should consider changing when I start using the phone.
I'm aware of the app that will make the adaptive refresh rate and I guess I'm going to use it right away.
Perhaps there are some good guides for newbies how to improve battery life etc.
I also dont want to get rid of the device warranty by doing any changes.
Thank you in advance for any help!
Hi,
To manage the refresh rate, you can use this app:
[App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods, QS Tiles, Tasker Support and More)
About this app: Refresh Rate Mods Change default refresh rates -Easily change the overall refresh rate settings of devices supporting multiple refresh rates. -Set supported mid refresh rates as the maximum refresh rate limit for battery...
forum.xda-developers.com
But beware, the S21 FE does not support adaptive refresh, only 60 or 120 Hz.
For battery optimization, there is a lot of discussion and a lot of differing opinions.
The best way to preserve it is to try never to go below 15% charge and never above 85%..... but this is difficult to implement!!
Or, you can also pay no attention to it and plan to change the battery when it begins to show signs of weakness
Finally, you can also optimize your smartphone by following this complete guide which does not require root access and therefore does not modify it irreparably :
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...
forum.xda-developers.com
Great.
Thank you for the links. Going to try those when the phone arrives.
Is there any option in wellbeing that changes 100% to 80% of the battery capacity? Perhaps this could be an option to prevent it from going to 100%.
There is battery protect, it limits charging to 85%
I've applied most of the settings and now I'm trying to debloat the device. Is there any recent list for s21 fe ? There is so many samsung packages that I don't really know if I need or not... Gettting a bit complicated there.
Also I wonder about restoring app before making a phone update. Do I need to reinstall all apps that I deleted and disabled before I actually make an update? and after the update delete them again ?

Question Poco F3 Overheating

I have had my device for 8 months without issues. Just 5 days ago it started overheating out of nowhere. Temperature can rise from 31 to 47°C between just a minute when I'm on a call. This comes with a huge battery drain during these spikes. Similar thing happens when I'm downloading or doing any network intensive activity. I used to get 7-8hrs SOT now I can barely get 3hrs.
When I switch to Wifi I don't experience this temperature spike and battery drain when I'm downloading stuff.
The heat is at topmost part, around the camera areas.
I have full LTE connectivity
Any help?
I'm on stock and I don't have any apps apart those downloaded from the playstore.
That means you can't help in any way.
Thanks
Never heard of this before. Try setting network mode to lte only. Go to dialpad and enter *#*#4636#*#*. Select phone information 1. Then under "set preferred network type" select lte only. Hope this solves it.
You can also change the sim to slot 2 and see if the issue persists.

I've done exactly that but still. The attached image shows the power draw when making a call.
I think it's a problem with the modem although I'm not sure. WiFi connection however is totally different, it doesn't spike up temps and battery drainage.
I have the exactly same problem.
What do you think might be the problem?
i have same issue
U have few options
1.root ur phone to a different os other than miui.
2.buy a phone fan cooler.
3.buy and expensive phone like Samsung s22ultra or the likes that have no overheating complains .
4. Wait for 5 years because a specific company is making ssd cooling technology and will implement that in phones in the near future . Then buy these phones.
Frustrated android user indeed .
Thanks for your suggestions
i found out that gallery is making these battery dragining and overheating problems.
SOLUTION: FORCE STOP gallery if your are non rooted user like me and use google photos instead.
BTW: they didnt fixed it with miui 14
I got my F3 ten months, and never experienced this issue.
I would suggest trying the following steps.
1: Go to Developer options.
2: Scroll down to Apps heading
3: Check background Process Limit. By default Standard will be selected.
4: Change it to either Atmost 1 Process at a time OR 2 process at a time.
I cant guarantee that the steps above will solve your problem but it fixed mine.
Try it and let us know if that helped.
