Hi,
I saw BravoMotolora's article about CPU binning, and I thought that it would be great if we compare CPU bin and voltages.
It will be great to know the relationship between voltage and PVS number.
Please follow this procedure
1. Install a custom kernel that lets you do undervolt, e.g. franco.Kernel
2. Do what BravoMotolora said
3. Undervolt your N5 by 25MV
4. Run Antutu
Then, you might see your N5 rebooting or giving you a Antutu score.
If you get the score, go and try the procedure again
I got to -50MV with PVS1 N5.
Please post your results(undervolt that you did and your N5's PVS) here!
Can you not do this?
Do not do what? I mean most of guys here will do undervolt to save battery anyway so won't it be good to share some intel?

I'm the same as OP... I have PVS 1 and the max I can UV is -50mV.
you do realize that many custom kernels set their voltages different than default/stock, and differ among themselves? for example, if you go -50mV less on using franco kernel, and go -50mV less using trinity kernel, it means nothing because their voltages differ to begin with. i mean you cant really compare each others voltages that way. you would need to write your voltages in real numbers, and cpu speed steps.
I honestly never saw a huge benefit in undervolting. It can also cause errors which lead to worse battery life.

agreed. i personally do better with underclocking, than with undervolting.

it's a lot easier to underclock 20% than to undervolt 10%, which approx. gives you the same active power savings. It's a lot safer too, if you don't have a spec sheet for the CPU handy.
underclocking does nothing to idle power (or leakage power) though
This phone does pretty well arlt idle I think. Can't imagine you would see much gain from UV.

I have a PVS 2 and can undervotl -75mV accross the board and -87.5mV at 300Mhz.
So 2,26Ghz I can run at 0.975 Volt.
CM11 with Bricked Kernel.
Together with Sync off, Google hotword off and optimized automatic brightness I get constantly 5 - 5,5 hours screen on time with websurfing, mail and music stream.

Underclocking drops the performance of the phone, as the peak performance is not available when needed. Undervolting on the other hand gives you battery savings without affecting peak performance at all. If done too aggressively, it can make the phone unstable, but there is never any danger of hardware damage. The instability will at most cause errors, random reboot, or a freeze up. If this happens, you know you've pushed too far under, and you can bump voltage closer to stock after booting the phone back up. If running stably, undervolting is actually marginally better for your phone hardware than stock voltage because you are wasting less of the energy in heating up the chips and damaging them.

i underclock, sometimes to 1036mhz max, with all 4 cores always on by default(no hotplugging). sure, in a benchmark itll score less, just like i expect to score more when im overclocked. but to the normal user, they would never be able to tell that my phone is only clocked to 1036mhz. meaning the user experience isnt lowered in any way. even intense gpu oriented games dont show that im running underclocked. so when you say it drops the performance, it isnt entirely accurate.

Sorry, but CPU underclocking means always a drop in CPU performance.
When you compensate this drop in your case by always having all four cores active you produce more heat with the active cores.
(and I estimate it will produce more heat/battery depletion than the original phone settings. (max 2,26Ghz and variable core usage)
When you argue that in general a normal user is not realizing a drop in performance due to underclocking...fine.
But it will always be a drop in performance.
Undervolting in opposite to underclocking produces no drop in performance but actually a rise in efficiency. (and thats what CPU/GPU development is all about).
Less heat, less battery depletion, same performance.
Why not taking advantage of that by undervolting?
Its free lunch.

I agree with you here. 1036 mhz is a great CPU speed for running the device and most apps. Most games UC the CPU for better battery temp like in PPSSPP. Less temperature throttle and more stable frames per second.
Benchmarks are a difference story though but who cares about those. UC is lag free, and buttery smooth so why not?

again, sure, if youre benchmarking the performance will drop, yes. but if its something that the user doesnt see or feel, then its irrelevant.
no extra heat is produced. also, i get 5.5-7h screen on time with very heavy use. granted, i use the browser much more than i game, but thats what i use my device for mostly.
when needing the extra performance, or wanting to, i overclock. everybody uses their device differently, has differing needs. i would never say one way is better or worse than the other way.

You can do everything you are already doing, but also undervolt, and your battery life will increase, without affecting your performance. Your performance will be different than my performance (because I don't underclock), however imperceptible as it may be. So undervolting is still better than not undervolting, even for you.
Using EX kernel 3.27, underclocked to 1.5Ghz, undervolted to "700 min" and using "stock" thermal throttling setting. Rock solid and it barely even gets warm now. Responsiveness and performance is only a touch worse than stock; the only places I really notice any performance reduction is in intensive games and app install times. Battery life is massively improved.
In some games i get lag spike like gta san anders play on medium seatings and rawensword 2 i use game tuner but not help . how to increase performance for gaming maybe custom kernel or overcloking if its possible for it or some kind programs I'm new in android staff.
If the graphics on the 815 don't work for you then surely don't replace it with an 813/819. The GPU is supposed to be better on the one you have.
I don't think these are gaming tablets really. I don't know any that are but that's not my thing. They do have more RAM and better screens than most other tablets.
any other option ?
Maybe Apple is better for gaming? I really don't know. Hopefully a clueful individual will answer you. I am too new to the whole tablet world to know much.
i find gltools maybe its improve performance i see a lot of video of it . but its need root access? who have experience from it ?
I guess you could change the thread title and perhaps get more help.
bump any suggestion? i need to improve performance for some games not to much a bit game now rawensword runs 20 fps sometime drops to 15 in fights :/ i like to boost to 30 fps any suggestion i try different programs but no luck :/
The issue is simple. The Exynos version throttles like mad with continuous high usage (games and video SW rendering). And you can do nothing about it. From what I read, the snapdragon version doesn't throttle as bad/at all. I recommend switching to android 6 if you haven't done that already, as it increases the performance by a little bit, as well as setting the resolution in those heavier game to 50% and force capping the frame rate to 30.

I've had the exact opposite experience.
The snapdragon version lags with many games while the exynos version played all these games smoothly...

It's certainly peculiar. I couldn't play Asphalt 8 for too long without setting the resolution all the way down to 50%(1024x768). At 1080p it'd start lagging really bad on me in about 3-4 minutes at best. That doesn't mean it doesn't have an adequate overall performance, it's flying, but anything as heavy as asphalt or worse would bring it to its knees.
strange in asphalt 8 i have no lag run rely smoothly only san andres and rawensword run not what great san andres 25~28 medium graphic rawensword 22 in fight with max distance other setting cant change.
For 5.1 I was using optimal rom found in development section. He also made a kernel you could over clock with synapse support found here http://forum.xda-developers.com/tab-s2/development/nn-kernel-lp-t701-t3309570.com With synapse you can force the gpu to over clock along with cpu. Download synapse from market. In setting developer options turn off hardware overlays ticking that on will use the gpu for rendering. Off (default) cpu. At least that is my understanding. Some games work better with it on others off. Minecraft on I got 60fps at 2nd highest view distance using customers textures. Yet terraria would stutter on certain conditions but never a problem with it turned off. Warning though it will make your device hot where the cpu is. I've got no idea how well you're games will play as I have never played them. I did get a noticeable difference from stock vs the above. So maybe it's an option worth trying.
Hm thx for advise but i read all posts but i don't see anything say it's for 6.0 marshmallow and my it's sm-t815 lite version i only see 810? Maybe its work for my device ?
Might be too different. Not sure.
http://www.devicespecifications.com/en/comparison/676f391aa
You have mobile data and I just have WiFi. Everything else seemed the same.
On my xoom it was from Verizon I flashed WiFi only rom and kernels. Lost mobile data but all was fine. As long as the kernal matched the rom. Worse case recover backup or Odin MM back on it. Just use the kernel with a 5.1 810 rom plus whatever you need to root it. I used that kernel with a few different romps but never cm since that's liable to be experimental still on my death bed. So it felt compatible with any 810 rom. If I was you and didn't mind losing cellular data I would treat it as an 810. Maybe do a bit more research and make sure they really are similar.
its same i see ok but one question if i flash this kernel how much i can improve performance like gta san andres can i play max at normal frame rate become on max now i have 17~21 fps i ask it become i was thinking its wort or not don't want to lose warranty
If you don't want to lose warranty then stock it is. That's my advise. I highly doubt you would break it but still if you dropped it in get it. You want that available. I've seen root options that don't trip Knox but I didn't care to research because I didn't have a warranty. I knew using ct auto root would void warrenty (method I used) before doing it. Search for different rooting options to 810.
I get not wanting to void warranty but if you're over clocking it, rooting, accept it as a trade off. You replied before I edited my last post so maybe reread. They are slightly different.
um when how about performance in gaming ? there i mention it i read it make 2.0ghz for 4 core and for others 1.5 or 1.6 it make huge boost in game or just small i rely care about it. ?
That sounds right. And the gpu goes up to 700hz. I think stock is 600. I don't play the games you are so can't say for sure performance but it was noticeable for me. I set both cpu min 1,000 max whatever max it allowed like you mentioned. So if it needed cpu it was there. Gpu I did max because there is a noticeable difference going from 600 to 650 to 700. Put the min as the max. Then toggle on turn off hardware overlays. Other games preferred the opposite. Max cpu for both and min close to max, whatever for gpu and no toggle for turn off hardware overlays.
Don't do max cpu and max Gpu. To much heat without any improvement. Pick one or the other as max, other one able to if needed. Here is what I ended up with.
Mine craft liked the first option. Not sure what it was playing at before over clocking. Maybe 30-40 fps while flying in creative mode. Got up to 60 fps no stuttering unless I was at a huge super dense forest biome where you couldn't see the ground. Probably used 25% per hour. I know mine craft doesn't sound like much but I had fancy on (transparent leaves), 128bit textures, 2nd highest view (it was far), and flying really fast in creative. Even bought a controller because of it. Though it actualy plays and feels better without. To wierd.
Terraria preferred all cpu so second option. Again you think but it's 2d. It isn't optimized by any means. Even on pc that game uses more then one would believe. I played at 60 fps with no slowdowns on second option. Without over clock it would stutter fairly easily vs completly smooth. It felt like whoever programed the cpu made sure they never gave enough power at any given time as a cruel joke. With synapse I could set the min as max and over clock it.
All I can say in the end it is noticable. It was enough to get 60fps. For a 2d game, it wasn't worth playing unless it was so. Download terraria dig a bit underground, get some lighting going and some enemies. Notice the wonderful stutter and ask why, it's 2d. Then you can decide if that vs 60 fps is worth the void warrenty and possibly broken device achieving it.
can y try gta san andres on max with overclock your system ? i'm rely curios
No.

It's very commom for any Snapdragon device to reach top clock speed when in use, download CPU-z and do a little scrolling to see that.
The lag in games you're getting is most probably because of the 3GB RAM of your variant not the CPU as SD660 can handle most mobile games with ease.
About battery life, how much SOT are you getting? RN7 should handle at least 6hrs with some heavy gaming included.
And about temperature, how much degrees is your device peaking at? Anything below 38ºC should be fine.
And lastly, about mi community......well, most people there look like VERY inexperienced users, i wouldn't take them as a parameter to prove your point.

3gb of ram is good enough for gaming unless ur playing a heavy game while on youtube and facebook at the same time. the problem with this phone is the aggressive thermal throttling, once the phone reaches 40°c the phone becomes noticeably slower.
my advice to OP is unlock ur bootloader flash some custom rom, custom kernel and root ur device until you find the performance/battery ur looking for.

3GB of RAM has not been fine for some time now, there is a lot of games you wouldn't be able to multitask with any other application with only 3GB.
Few examples: TES Blades, Fortnite, PS2 emulation.
Also what are you doing to reach 40° on your device? As for mine never passed 38° and I live in a hot country(Brazil).
I Agree with installing a custom Kernel to improve your performance overall, but right know the best optimized ROM is still MIUI as many threads here suggest.

im in Philippines, room temperature here is about 37° heavy games like pubg makes my phone temperature skyrocket reaching up to 45° especially with thermal mod.
btw MIUI has the worst ram management for this phone. its closing background apps like no tomorrow, but on any custom rom its actually quite decent.

Thanks for all your reply, i apreciated it. probably i will wait until miui 11 released, and if the phone still gets hot i will install custom rom and use EX kernel manager to disable input boost and limit the cpu.

these are very stable, miui-based custom ROMs with zero bloatware and better RAM management.
still a better ROM for people who want better performance / battery life on their xiaomi devices, but too afraid to live on the edge with AOSP ROMs.
AFAIK, that's called thermal-throttle/ing. When RN7 reach its peak performance and certain heat, to prevent overheat normally our device will slowing down its performance and it caused lags and fps drop for sure
I also encounter this problem when playing pubg even with smooth-ultra setting

It happened to me, custom roms aren't good for gaming then switched back to MIUI, when I play phone gets 45 C max, my battery gives 6 hours of straight online gaming, I'm on MIUI Global 10.3.5, Evira kernel 3.8.
:good:
660 wasn't designed for battery efficiency. Still waiting for Franco Kernel, it might fix the issue. My Redmi Note 4x can last up to 10hrs SOT while my Redmi Note 7 can only reach 5hrs even with custom ROM+greenify installed.

Nope. With moderate use I barely get 7, mostly 6. I got this sot by using apps like line, wa, instagram, youtube, browsing, downloading tons of file and one match playing pubg and pes.
I reach 8 to 9 hours sot only if i using wifi and playing videos constantly, minimum social media and no gaming.
Ofc people used their phone different each others. But, im sure they are having same battery drain. People talk about this so many times and everywhere. Ur case having 10+ sot like only happen 1:10 of all lavender users.

Its true continuous gaming on this phone (with stock miui) is bad. You will get smooth gameplay only in short term, like a one match pubg. Then it will start to lag because of heat. We need to keep the phone temp as cool as possible when used for gaming to get less frame drop. Example, playing close to a fan or inside a room with air conditioner on.

AFAIK, that's called thermal-throttle/ing. When RN7 reach its peak performance and certain heat, to prevent overheat normally our device will slowing down its performance and it caused lags and fps drop for sure
I also encounter this problem when playing pubg even with smooth-ultra setting

Yes, thermal throttle where the main reason. Its limit cpu whenever temp -read by system- reach 43/44 degree. A temp read by system are mostly not indicate the real temp. Besides, we have clockspeed max at 2.2Ghz, making our phone faster to heats up easilly. Thats why thermal throttling the cpu in such early time. (Its ruins gameplay, isnt it? :v)
If we look inside thermal-engine.conf on lavender, it use two sensor for detection and two step for throttling the cpu. First step it will limit clockspeed by 1,5Ghz and 1,9Ghz. Second step it will limit clockspeed by 1,1Ghz and 1,4Ghz. Because the temp gap between these step are only 1°, so mostly thermal-engine will going to limit clockspeed by 1,1Ghz and 1,4Ghz. Imagine play pubg with that clockspeed, lags and frame drop will occurs oftenly.
I've seen Mi 8 Lite with the same chipset playing pubg continously without any frame drop. I took its thermal-engine configuration and compare them with lavender.
Interestingly there are specified profiles for gaming and pubg are missing on lavender. Thus, both thermal-engine are really different. A same chipset should having same thermal at least. But, this show us that lavender thermal thingy are not being optimized yet while mi8 lite does already.

Lol. Agreed XD
Im gonna Re-Unlock my bootloader for the third times and use custom rom when they fix Hals. Till then i stay on miui hoping miuidev did an improvisation with next update.
Has anyone compared if the 12.0 releases have better thermal performance as compared to the 12.5 release?
My K20Pro running on 12.0 is much cooler than my 11Ultra running 12.5. Sure, people have been saying that the snapdragon 888 runs hot but at the same time I've been seeing reports that other devices include the Redmi Note series are also experiencing heat issues after updating to 12.5.
Honestly for me heating has never been an issue, what do you think a good thermal would be like for you?
Probably like not reaching 39C for anything non-gaming or video calling activity?
Mine is not reaching it
Good for you. Many others are unfortunate like me
What is your room temp?

I felt the same way. I used it for 2 days with 12.0.9 when i got the mi11ultra and i didnt feel the heat. When i updated to 12.5 e felt it.
wondering if its possible to downgrade without bootloader unlocked?

Room temp doesn't matter, not when it comes to the 11Ultra. With AC on at a comfy 24C as opposed to just a fan with a room temp of 29C its still the same heating issues just a matter of the ramp up time for heat.

Damn, so its much better on 12.0.9? I'm going to flash 12.0.9 this weekend. AFAIK, downgrading either way will require a wipe and I think you'll need to unlock BL either way.
May be not what you are looking for, I rooted the phone for CustoMIUIzer tweak. I also installed Franco kernal and there I underclocked the kernal CPU by 25% (75% working) and optimized its GPU. This has dramatically improved the thermals and battery performance. Idle temp of the phone drops to 25C regularly. For the past one day, it has not reached 37C when doing routine browsing, calling and texting etc. The temp jumped to 40C during HD video playback, and once to 41C while playing angry birds. During quick charging at high ambient temp, it touched 44C once. Normally with the Mi quick wireless charger (80W), the temp variates between 40-43C.
Im yet to notice the anticipated drop in performance of the phone. For routine games and HD video playback, 75% performance of this beast is enough so far. It is as smooth as it is supposed to be.

Buy the fastest most expensive cpu on the market and then cripple it!?

According to my daily use of the phone, I do not need the full processor power. Seventy-five percent power is enough for that. For some long tasks, such as reading a lengthy pdf or google maps on a road trip, even 50% CPU power may be enough, granting enhanced battery performance and heat management. For the most intensive tasks, I can restore it to its original might (or even overclock it for that matter) just by toggling a switch, if that shall be desired. Options are good to have. A software fix and aggressive management of heat officially by Xiaomi, the point here by OP, will be welcomed of course.

actually a snap865 is really really fast and more then capable of running everything except gamming in comparison, and if you don't game high 3d games then you don't need the full power of the snap888 which is 25% faster.
I actually paid 850€ for mostly the camera and the media comfort, so i have to agree with hellodrsoul, if your main goal is have a phone for this purposed(no hardcore gaming) then capping it is a good thing,
also yeah Xiaomi is lacking in the optimization department.
on March everyone was stating in news about the mi 11 ultra
World’s First Full Phase Change Heat Dissipation Technologyeither it sucks or xiaomi software team is at blame.

Yes, Franco Kernal manager. The link is https://play.google.com/store/apps/details?id=com.franco.kernel
You are right. There are no custom kernals available yet. But the FKM has the option to underclock the CPU and GPU and for me it works flawlessly.
Hello
I have upgraded my Tab S7 to Tab S8. And I have expected new device be much faster and smoother, but what I found that games are really lagging! It was perfectly smooth on S7 but not on S8. Game mode does not help much. I do not play a log of games on this tablet as I used it mostly for developement, but I do play Harry Potter Puzzle and Spells and this game lags pretty bad on S8.
What can be done to fix it or should I wait for Samsung to release update? I do know about Samsung's throttling on S8 devices but I never expect it to be that bad.
And in addition (don't want to open another thread) it seems that S8 has more aggressive memory settings because it unloads apps from memory over time. Which never happened on S7. S8 has more memory and I think it should keep more opened apps, not reloading them. And yes, settings in developer section (do not keep activities) is not enabled

This has to do to android 12, s7 was only on android 11, but also is on 12 now. So then it automatically puts apps into deep sleep. You can remove that under battery settings area and remove apps from deep sleep mode.
About lagging it might be new game mode from samsung since apparently samsung did on purpose limit hardware but added a settings into app that let's you gain more performance in games. Should be in game engine or w.e name is and then settings and then Labs and enable experimental feature there that should boost performance and stop limit the hardware for game.
When I replaces S7 it was already on Android 12 but I never observed such behavior. Anyway, I have put game into never sleep list. As about lags, unfortunately I found no options for that

I was noticing this particular with emulation since I don't play many native android games. When playing Sonic Colors at native res on my Tab S7+, it would almost never go below 30fps in level, and almost never below 60fps in the hub and menus. However, when I tried doing the same on the S8+, I had a bunch of stuttering and performance issues no matter what version of dolphin I used. There was a workaround to this (at least for me). These issues only happened when I restored my data to my new S8+ with Smart Switch, but when I just put all my data and stuff on there manually, the issues seemingly stopped happening. The only game I throttle in is Fortnite, which didn't have the 90fps option even though the S7+ did. The game still didn't feel much different before and after the throttle, still pretty consistent framerates overall.
Edit: Just fixing typos.

Did you used cloud backup or restored through cable or it's the same thing? I have similar problem, but with benchmark results. My device can't get even average model score in 3DMark (about 2 to 8%). Geekbench scores are worse than snapdragon 865 devices. I don't know what's going on. I already tried to reflash stock rom with odin, but that didn't help. Hopefully not using cloud backup will help.

I initially restored with a cable, but once I started getting shawty performance, I made a backup on my sd card and restored it from there with Smart Switch. I never used cloud backup since that takes a lot of time for me. After getting suboptimal results with both, I just bit the bullet and slowly started adding everything and getting it to how it was on my old devices. Only then did I get getting substatiall better results. Now I can run a lot of Wii/GC/3DS/PS2 games at 1.5x, 2x, and sometimes even 3x without getting throttled. Not sure why using smart switch tanked my performance, but all I know is that it's not tanking now.
Thats interesting. Because I also moved data using cable. I do not know how good is cloud since I never did it before (only on Apple devices).
I might try to fully format tablet and test it again.
Will provide more information later

I tried formatting few days ago, and that didn't help. At least for me this problem is not related to Smart Switch. Do you also have bad benchmark scores? I understand that benchmarks are not very good indicator of performance (especially due to GOS), but I expect to have at least average SD8gen1 performance, not the level of SD855.
Did reset to factory settings. It is much better at least for now. Benchmark - tested only Geekbench 5. Result the same
Hi.. I'm experiencing the same problem here.. any updates regarding this problem? My geekbench score can't even surpass an exynos 2100.. it only achieve around 700ish on single core.. the first time I notice this is when I tried playing granturismo with aethersx2.. and it can't even handle the 1x reso.. hhhh.. really frustrated here.. please kindly share any clues regarding this topic thanks in advance.. sorry not a native English speaker
I had same problem, but, i solved using this:
ADB AppControl 1.7.5
(disable all game service (i'm not remember how many)). For me it's work great
--edit
i disabled bixdy and others apps too
First.. thank you for the answer! Might try it out later..
So it's like disabling the "GOS" right? Is it different from the "alternate game performance" option in game booster? They said it's the "official" way to disable the GOS.. but yeah I didn't find any difference after enabling that option though... Hmm..
Hmm...also.. What makes me wonder is.. I saw some reviewers review this device without any tweaking needed and they could achieve a 8gen1'ish results in benchmarks.. and also if you know ETA prime on YouTube.. he reviewed a tab s8 ultra and is able to run a granturismo 4 with aethersx2 (ps2 emulator) in 3x reso in default settings with no problems... I know it's a different device but it's supposed to have a same Chip right?
All of this things makes me frustrated because it was not what i expected from a 8gen1 device.. moreover I saw a sd870 device could run the granturismo 4 in the same settings with no problems.. it really broke my heart..
The issue mainly lies in the SOC.
Even though, SD8 Gen 1 has a much higher peak performance, especially in GPU, it can't sustain that performance due to excesive power consumption which results in thermal throttling.
GOS is another thing that affects the whole experience, it's limiting the performance of the device.

Yeah.. I think this is mainly what cause the problem.. The 8gen1 itself..
a quick update regarding this from me..
I've done some re-test in benchmark and real game perfomance but this time im doing it in a well conditioned (cooled) room..
previously I was doing the test and gaming and in a room without any Air Conditioner and I lived in a tropical country which is really hot and humid...
the benchmark results (3d wildlife) came out Nice in a well cooled room, It scores what most of Tab S8 would score and the real life perfomance (PS2 emulator) is also improved..
it manages to handle GranTurismo 4 in aethersx2 with 3x reso on safe setting quite well..
the CPU temperature is well managed in around 35'ish Celcius compared to 45'ish when not using any air conditioner...

CPU temperature 35 Celsius degrees? Are you talking about an ABSOLUTE idle? Because even if you would put a bag of ice on the TAB it wouldn't sit that low under usage. Even small loads will put the CPU around 50-60 Celsius degrees. Under heavy load up to 85-90 till the thermal throttle hits in.
Also, that ONE wildlife mark test doesn't do much. The idea is stability, better known as SUSTAINED performance, and that's where SD8 Gen 1 ****s itself. Try running a Wildlife standard stress test (20-minute loop) and post the screenshot, you'll see what I mean.

I only saw the perf-z indicator from samsung though.. so yeah.. i know i might just straight up wrong about this I just straight saying what I saw.. and honestly I'm not an expert in this.. just a mere consumer..
Yeah I got you.. it goes downhill even after the first one.. what I'm trying to say was that I never reach that score before in warm room so yeah it's mainly the CPU problem..
What mainly being my concern before was I'm scared that I got scammed with a fake/unoriginal/refurbished tab s8.....
Harry Potter plays fluently on Tab S8 Plus here.
I have sent my S8 to my mom and bought S8 plus. Did not restore, set it up from scratch. No lagging in games, including HP. So, it could be related to thermal soliton in S8 plus as it is bigger

Yes you have to run 4 adb Commands that also disables game booster and game launcher then GOS will stay disabled even after restart. I've done this and turn ram plus off. I also disabled or put into deep sleep all of the bs apps. I also went to advance features and turned off all of everything causes I don't use the s-pen so no need for air actions and stuff to be on. If you want the ADB commands let me know.
