Surface Pro 2 CPU Limited

Hi all,
I've had my Surface Pro 2 256/8 since release and all has been fine until (possibly) the firmware update.
Turbo Boost was working fine and the CPU was going up to its maximum of 2.6Ghz but it is now seemingly capped at 2.23Ghz.
I've checked in PC Settings, Task Manager and CPU-Z, the maximum that the CPU ever reaches is 2.23Ghz, as indicated.
Anyone else experienced this? I have tried all power profiles (Performance, balanced, Power Saver and there's no difference).
Thanks!
EDIT: Having used HWiNFO64 on the High Performance profile I can see that the core is limited to x23 which is producing the 2.3Ghz clock speed. It occasionally indicates x26 (2.6Ghz) for a millisecond before ThermMon shows that it is being throttled back to x23. So it appears it's not reaching maximum speed to keep the heat lower, why this has happened is still inconclusive..

Have you tried to change the CPU maximum utilization in power settings?

>I've had my Surface Pro 2 256/8 since release and all has been fine until (possibly) the firmware update.
You've answered your own question. One reason to cap speed is for battery life. That's what the latest firmware update provides. You've found the downside.

So they cap turbo mode to increase battery life, given the SP2 is advertised as having an Intel i5 CPU with no mention of speed on the MS site I think they'll get away with it...

Well, in that case, the CPU shouldn't be capped when NOT running on battery power, should it?

There is also cooling to consider regardless of if it is on battery or mains. Although was heat particularly problematic pre-update?

>Well, in that case, the CPU shouldn't be capped when NOT running on battery power, should it?
As another noted, SP2 slicks never said CPU would be running at max spec.
PCs are normally more configurable. But if you enter SP2's UEFI setup, the only thing you can change is Secure Boot. MS is emulating Apple in more ways than one.
The cynics among us (guilty as charged) would say that MS handled this just right: Release the device with uncapped speed to get the best possible performance for reviews. Then afterward, cap the speed to claim "improved battery life" as well. If MS had capped the speed to start with, SP2 would be no faster than SP, and would get slammed hard. SP2 is already slammed as having minimal improvements over SP.
Reviewers aren't going to take the trouble to revise their reviews, and even if they did, not many people will re-read them. So, with this method, you can indeed have your cake and eat it too. Think of it as a more "legal" form of juicing performance tests without the explicit cheating that Samsung and others resorted to.

Anyone thats knows the difference between the CPU's will know that theres not a huge speed increase though, the only thing they should of done was stick a decent SSD in there, I've got an unused PX-256M5M sat on my desk that reads/writes at near on full sized 2.5" SSD speeds where as the mSSD's have always had half decent read and poor write.
Other than that what else is there to improve on, the camera perhaps as per the Surface2, battery life, check, the only other thing the Pro/Pro2 needs imho is more accesories, yes they are coming but should of been ready at launch imho, I'm crying out for a dock...

Overheating

Hi, 3 day ago I recieved my Mi4c (3gb) and just after couple of minutes surfing on the net I realized, that the top of the phone is really hot (the bottom was normal). The next day I tried it with game - after just one or two rounds (about 2 minutes) phone got hot again - again at the same area. I downloaded some app and I looked at the temperature after running the game - it showed even 55 degrees Celsia. Is it faulty piece or is it just software issue, which can be fixed by different ROM ?

Under load, the SD808 can get pretty warm.
Add to that the fact that MIUI (in all of its various forms) is a steaming, overheated pile of rhinoceros feces and you have a terrible combination just asking for heating problems.
TS CM13 does a pretty good job of mitigating the software issues that lead to heating.
The phone will always get warm when playing moderately intensive games or when used in direct sunlight on warm (30c+) days.

I found that the miui versions some vendros provide are manipulated or corrupted by vendors,
I suggest you check if your bootloader is unlocked, install a recovery, do a total format (not a factory reset, a full system format from recovery) and install the latest miui,
I had overheating issues and the phone would eat the battery away in less then 12 hours, i did this and im currently going on 39h standby and around 1 - 1.5 hours screen time and i still have 34% of the battery life.
Clean house, start from zero and you might be surprised.

Just installed MIUI 7.1.6.0 Global stable from xiaomi.eu and I like it more tham MIUI 8 already. Plus, phone seems to be a little cooler. Snapdragon 808 is still a hot chip though, so don't expect miracles.
Switched from MIUI 8 because of heat and battery life issues.

I tested different rooms and every room has overheating. The only difference is the time the systems downclock the CPU.
In cm13 I changed the values so it doesn't close the big cores so fast.
But the big cores are still the most time off.
Normally my Temps are between 40 and 60 °C
And that's bad.
Miui doesn't change anything.. Only the time of throttling.
I don't need a phone that throttles itself when turned on.
When I'm home I'll try to open the back cover and take a look.
Maybe I can hard mod it in some way.

I'm facing the same problems here.
I use dual Sim, so I thought this could be the signal usage. But my battery is draining faster and faster. Some times even dropping from 14% to 10% in 1 sec!
When using wifi, the cpu reaches over 50ºC (currently 57-59ºC). MIUI 8 didn't help much.
I'm using my phone a lot, 3G and screen on for long time, but it's dropping from 100 to 15% in less than 7 hours...
Is there anything that I could do?

Install MIUI 7.1.6.0, temps and battery are better, or go Apollo the way and flash CM13 or Slim

I have over-heating problem too. Specially by keeping screen on for several minutes. I'm on miui 8 by xiaomi.edu

The overheating is caused by a ****ty rom some vendors use,
Install the latest recovery, and do a full advance wipe (everything except OTG USB), then do the format,
DO NOT REBOOT the phone, connect it to the PC and copy over the latest miui weekly (i used 6.9.1) and flash it, then see if it keeps overheating.
Apparently some of the malware some vendors install are hard to get rid of, i had weekly, monthly, slim6, Teamsuperluminal and Omni rom installed, and they all showed the same issue. it wasnt until i did this "sanitation" process i managed to get rid of the heat issue.

You found some way to hard mod it ? =) The snapdragon 808 would be very powerful if there aren´t that overheats.
Making some holes in the back cover (get out hot air) or give more space (case is extremly tightly built) ? A heat pipe (passive cooling)?

Things are a lot better using an undervolted kernel. Built one from kuma sources (not for MIUI), I could share if you want.

nice idea with passive cooling
i glued my nhd 14 to the back that helped
no serious i dont have any clue to make the phone cooler with hardware modifications.
without the backcover it isnt cooler. the difference isnt noticable.
i would say how the cpu is build into the phone is wrong.
for me the phone isnt worth it anymore. im moving to a BQ or the HTC10.
why should i use a phone that i have to downclock to a fraction of its performance ?
or i use normally and get throttled after 20 minutes?
and it doesnt matter which os i use any miui or cm version suffers from overheating.
so i think ether xiaomi make mistakes while building the phone or it is just the bad 800 series.
but looking at the lg g4 the picture is the same. so qualcomm is to blame for it.
sorry for this but the only solution is to use a fan on the back OR the better solution buy a better phone ;(
edit:still finding grammar fails

For anyone willing to try this is an undervolted kernel based on kuma's sources and a modified msm8992-regulator.dtsi with lower ceil voltages.
Tested only on CM13 but should work for other ROMs based on CM13. It can make your phone unstable (freezes, crashes), so before you try either keep a backup of your current kernel or simply boot (don't flash!) the kernel to ensure that everything works normally:
Code:
fastboot boot undervoltedk.img

@Ydraulikos
im already using a kernel from kuma (Resurrection Rom) and yeah its very great, less overheating. The Rom itself is slim for less heating too.
But its overheating though while playing 3d games for a longer time.
@kar5ten
..nhd 14.. that would look funny xD.
Yeah the problem is the cpu. Snapdragon 808 and 810 suffering from overheating, 810 more.
But xiaomi could handle this too. Not use this cpu or built better cooling system, instead make it as thin. The most temperatures i have is on the top right. If they used passive cooling like pipe heats for distribute the heat, we don´t have this problem or rather less overheating.

@Ydraulikos thanks i will try this.
@Danny94
i made another test.
i use resurrection rom 5.7.1 with oc kernel 1.12 (intelliactive gov.) custom temp. throttle at 75 C
i opened the back and added aluminium foil .
10 layers on the upper side where the cpu sits and 6 layers above the battery and the cpu. they both are connected.
now i run antutu 3-4 times and i got these results
75899-74012-70371-68155
with max temp of 53 C after those 4 runs.
the idle temps are now at 30 -35 C most time
but i only tested it for 2 hours

@kar5ten
oh nice that sounds like a good idee! And withouth foil wich results you get, antutu - temps ?
The Alumiunium foil could take the heat from the cpu and distribute it over the device, for better result thermal paste as connection between cpu and foil could help.
Maybe with another material (foil) you could improve it as well. The best result you would get maybe if the backcover consists of metal, this way you could get the heat out of the phone, air cools metal. (problems.: back cover can get hot, you can heat back cover with hands[maybe a case])
Care about that foil doesn´t heat up the battery and the metal can disturb radio signals (gps wifi mobile data).
Could you share a picture as well of your modified version here in the forum, maybe one too please how it looks inside. At the moment i don´t have a plan how to open the back cover. =)

I will post some pictures but next weekend. Before I open it again I want to test it.
I don't know the exact results from antutu before I modded it.
First 75k
2nd 60k
3rd 55 k
At the moment I didn't noticed any signal drop or something.

Hi,
Did you have the opportunity to take some pictures of your mi4c modding?
would be also great to have a slight bigger case it probably help with the overheating.
best regards,
John

@patadas I get a new case this weekend. Then I will take some photos.
But the problem is to open the phone

Question Poco X3 Pro state

Hi, I am thinking to buy x3 Pro, but at first i want to know if all problems are already fixed.
I read a lot of comments about problems, but most of these comments are 3+ months old, so...
1) under load it gets very hot. Throttling...
Just by running Antutu benchmark few times, you see how score drops over 100K.
2) Touch issues
3) lags in games, Laggy UI, delay when scrolling
4) fast battery drain
5) network Issues, unstable data connection
6) unexpected shutdowns, screen freezes
7) back panel vibration when audio is playing
There are more, but these are most common.
I hope most of these problems come from their "amazing" MiUI, and can be fixed.

I can only confirm point 7 but it's not so noticable unless you are banging music at high volume.
No heat issues but then i'm not running Antutu over and over. No touch issues here but some people mentioned it. Laggy UI? First time hearing this lmao. It's butter smooth even on MIUI. I get 3 days of battery life with 10h SoT on average with 120Hz, i dont think it's bad.. plus i'm using navigation (GPS) and camera quite abit, you can probably get more than that easily. Never had any network or random shutdown issues (almost 20 days uptime, since last update of ArrowOS) probably some people with magisk / mods reported it.

I would agree, although I'm not going so good SoT (but since I'm a light user I still get very good battery life).
Never forget that people report issues, not good experiences. If you look at each indvividual grievance, you'll never buy any phone anyway

"i'm not running Antutu over and over"
It's just one of ways to put your phone under load and immediately see/compare results.
Many smartphone reviewers do this test to see if phone will throttle.
Check this video:
I found video where we can see x3 pro from inside.
On the left is x3 NFC and on the right x3 Pro.
Very interesting decision for x3 pro.
There is copper tape, instead of metallic plate.
Plus, you see that thermal paste is only on memory (3x pro).
If they don't use paste and there is not enough pressure then heat will not be dissipated by pipe.
And here you can see how much they use thermal paste between tape and pipe.
3 small lines on CPU and a bit for memory.
Just look how much more contact surface is on x3 NFC.
Now i understand why x3 pro is so hot.
If your x3 pro is not hot, then you are lucky (there is enough pressure/paste).
If you are not lucky, then idk. It's faulty phone.

1. Yes, the phone gets really hot, but that is only while gaming, especially when on mobile data. I just bought a cheap cooler and everything is fine
2. I had problems on AncientOS only, now on Crdroid i dont have it
3. Games dont lag, ofc u cant play Genshin Impact maxed out, but overall the gaming experience is smooth. On Crdroid i have no problems with scrolling, but i also use Samsung Browser and Relay for Reddit, Chrome and Reddit app were laggy even on custom roms
4. Battery drain is a problem of MIUI, on custom roms i get 8-10h of screen time from 100-20%, but i feel like i should get more than 2-3h of gaming
5. & 6. No problems
7. Yes, the back of the phone vibrates while listening at max volume, which is to be expected with how loud the speakers are and i dont see how this is a problem. Did the people who complain about this ever hold a speaker? Even overhead headphones vibrate while listening at high volume.

wait, only 2-3 hours of gaming and battery is empty?
"Yes, the phone gets really hot, but that is only while gaming"
I think we all will agree that it shouldn't be like this. Either Chipset is hotter than they expected and cooling solution used in older models can't handle it. In this case they had to slightly undervolt/downclock. Or they have huge % of faulty phones (cooling problem) and they simply close eyes on it.
But maybe it all goes by the plan. They know that chip will be hot, but it's fast and it's enough to get good sales.

Yes, its around that, but i mostly play CoD mobile and Wild Rift maxed out, so that might play into that.
I also agree that the cooling solution isn't that good to use this phone to the max and no update will ever fix it without a performance drop. Honestly this device would have been better suited with a SD855, the SD860 is too hot for the device, or at least the body of the phone didnt allow for a better cooling solution. But i guess they didnt want to have a 2 years old chip in a new phone, even if overall that would allow the phone to work faster for a longer period of time.

It's not normal. It's defect, same as cooling system.
Here you can see comparison with Redmi Note 10 Pro at max volume.

Being honest i really dont mind it, actually i enjoy it, the speakers feel powerful.

I feel many of the bugs described on first post and I find it a real shame what POCCO has done with this phone. Cheap phone? Yes! Powerfull? Yes! and... It works as expected? No!
On the other side, there are more than 10 different ROMs available for this phone and most of them are the same. Same bugs and same problems but with different skin.
I loved this phone but after see how it evolves, i feel like i did a bad investiment. Next time i will go for Realme.

I had some of the these issues when I was on miui and before unlocking BL. Phone gets warm during gaming which is perfectly normal and on par with other phones.
I sold my galaxy note 10+ for poco x3 pro, it was the best decision I made this year. Gaming got better with no throttling on custom rom, more fluid, better battery life, native google ui.

how many hours you can play games, or watch videos?
For example, on Realme 8 you can play pubg 6-7 hours (14%/h). On poco x3 pro, around 4 hours (23%/h) But can you squeeze 6+ gameplay hours from x3 pro on lower settings?

I haven't tested that long prolonged gameplays. My comment was against my previous phones - galaxy note 10+ and black shark 2 and it easily lasts for 2 days for my usage. But 4 hrs in 23%/h is still a good life, isn't it? don't get killed yourself playing for so long

Pointless comparison, Realme 8 SoC is about twice slower. It's like comparing if Ferrari or Volkswagen Golf will empty their fuel tanks first. Ofcourse Ferrari will but there is a reason for that. Not to mention 120 vs 60 Hz screen.

Dude turn off this "protective" mode. I am not comparing, i am asking question.
I understand, you own this phone and it's most amazing thing you ever had.
"It's like comparing if Ferrari or Volkswagen Golf"
Reality is that there are more powerful phones on smaller batteries and they live way longer then poco x3 pro. For example poco F3 with 4520 mAh. Even if x3 pro has 5160 mAh, it's battery is empty at point where F3 has more then 20%. And both phones has 120Hz screens. Only difference is that F3 has amoled display.
k3lcior, i am asking question (it's not comparison): why F3 with smaller battery lives way longer? Is it because of amoled display? Is it because of chip which is hot as hell? or?
if we compare processors:
Snapdragon 870 vs Snapdragon 860: tests and benchmarks
We put Qualcomm Snapdragon 870 against Snapdragon 860 to find out which SoC is better. See performance comparison in benchmarks and games.
nanoreview.net
we see that "Efficiency of battery consumption" is the same, so problem shouldn't be in cpu.
so, amoled display does all magic?

I'm not defensive and no it's not most amazing thing i ever had. And yes you are not comparing, but you are asking to compare no?

It does save battery when there are blacks on the screen because they are not 'powered' on AMOLED screens on that large screen it can make large difference. There are also more small details which also can make some difference for example SD card slot, Poco F3 doesn't have one and Poco X3 Pro has one which has to be powered at all times.
Not to mention GSM signal, small signal difference can easily make several % battery life difference which can be easily manipulated hence why these comparisons are idiotic.
And btw. here is less than 40 min. difference in battery life from what i see.
Edit: Also UFS 3.1 in Poco F3 is more power efficient compared to UFS 3.0 in X3 Pro.

Question was, if on poco x3 pro you can squeeze out 6+ hours of pubg gameplay (even on low quality).
Everything else was just additional info.
Why i am asking? Many poco x3 pro owners wrote that battery life is bad. I am trying to understand if problem is software based, or hardware. If software, it can be fixed, if hardware, then you have powerful phone with bad battery life. If F3 and X3 Pro are both on the same soft, then seems that problem is hardware based (IPS screen).
I saw this test and F3 has 24% of battery when x3 pro dies:

Question x3 pro about undervolting....

hi people i am curious about undervolting and underclocking. is there a possibility that i can make my phone more enerrgy saver?? i don't need too much performance, i am just playing pubg at lowest settings 60fps and thee phone gives more than i need (i think). So... i need enough performance and longer battery life. what can i do

The biggest power consumer in the device is probably the display and not the CPU/GPU. Even if you undervolt, it's only a few millivolts anyway and that would hardly do anything. Setting the display as dark as possible would probably be the most efficient, although this won't work miracles either.

Of course, the CPU/GPU of the X3 NFC (5W TDP) consumes significantly less power compared to the X3 Pro (10W TDP), which means that the Screen On Time is higher compared to the X3 Pro. A computer with a Core i3 CPU and a GTX 1650 Super also consumes less power than a Core i7 with a RTX 3060 Ti. You can of course undervolt the CPU/GPU of the X3 Pro, but you will probably never get the power consumption close to the X3 NFC. The cores architecture, clock rates, the internal memory and the memory bus + RAM speed used in both devices are also different, so that you can't really compare them.
The SD860 is about twice as fast as the SD732G (at least in synthetic gaming benchmarks), so it should be clear that this additional performance has to be bought with additional consumption somehow.

They are very similar but not identical. Nevertheless, the guide for the 9T Pro should probably serve as a good reference. In any case, make a backup beforehand, every chip reacts differently. I wish you the best of luck and let us know how it turned out.

i found this

For undervolting you would probably need a custom kernel.

Underclocking is not worth it.
I did a full-time test on NoGravity Kernel with PC Mark. Way worse performance and a ridiculous 30minutes gain (minimum screen brightness)
Left is normal balanced Profile. Right is battery saver with reduced maximum frequency.

sir please can you try this on lowest frequency( i mean 720g-like performance )?????? im not expecting to work battery test, it takes too much time so dont hurt yourself. just what are your thougths

Approximately half of the CPU cores would have to be deactivated completely and even then the 720g would probably still have the edge in terms of power consumption, because the GPU of the SD860 also has three times as many shader units as that of the 720g and accordingly it consumes more power.
Years ago I played around a lot with UC/UV on smartphones, but in the end it wasn't really worth it. And it seems that it's still not worth the effort, as Haldi4803 has shown with his post.

Yes sir you are right!! 60hz is working good on energy saving. One more question: in the screenshots, first graph is beginning when %90 and the second %75. is there a wrong thing???

Battery saver preset already reduces big cores to 1400mhz or something like that.
You see performance from 12'000 to 8'500 which is about 30% performance drop. But there is no 30% Battery life increase, but only 3%.
Might be different for GPU underclocking. But I haven't really taken a lookt at that,as I don't play games on my phone.

No. Both started properly at 100%. The app just fails.
You can see the 2nd screenshot go down to 20% at Pass 80 but then still going over pass 120.

Thank you

i got two simple solutions.
1) set framerate in pubg to smooth and low at the beginning of the game. when you go for fights just increase it to extreme. also set low framerate in lobby. this will definitely keep device cool and save a lot of battery.
2) use venella os and freeze all the apps with icebox app. leave only few apps this will also makes device cooler while playing games personally i have noticed calyx os keeps this device very cool.

Themes / Apps / Mods Cool dowm your Tensor

The Tensor G2 processor on the pixel 7 series has poor energy efficiency, which will cause the phone to heat up easily.
Therefore, I decided to limit the CPU clock frequency of the Tensor G2. By adjusting the overheating threshold, the CPU clock frequency limit can be achieved. Keep your Pixel 7 Pro super cool, not hot at all, and with longer battery life.
I made a Magisk module for your input, if you are also troubled by the heat of Pixel 7 Pro, then you can try this module.
Here is the download link.

My Pixel 7 Pro is already cool. Never ever even mildly warm. But i dont play games

With the case on, when charging it reaches 40 degrees. But otherwise it's... Ok I guess?

Summer is coming and he's going to be hot, using a Pixel in China.

Thank you!!!

Great, I had to test this. I have the Battery Guru, and I have set the temperature to 30 but it always prompts, even when I am using it for minimal work. Can you share some performance benchmarks, either with Battery Guru or Better Battery Stats? and the source on github?

Great i want to test

Not trying to be negative as I like this idea!
'The Tensor G2 processor on the pixel 7 series has poor energy efficiency'
Do you have data to proof that or are you guessing?
'which will cause the phone to heat up easily'
I have not really noticed that. in fact my Galaxy Note 20 Ultra gets much warmer than the p7p.
Curious what the actual performance gain and heat reduction will be (in numbers).

Data to prove that the efficiency of G2 is poor? Sure, sir.
This shows Tensor G1, and Tensor G2 introduced an additional X1 core (2x X1 cores) and didn't improve the efficiency much apart from being slightly more efficient since it's based on 4nm.
So, long story short, G2 is somewhere between Exynos 2100 and 888 when it comes to efficiency and neither of these two mentioned is really efficient.
Pixel 4's SD855 is more efficient than both Pixel 6 and 7. lol
There is plenty of power measurement data and how the SOC behaves under load, feel free to research.

mind posting the correction of values? at what temp it starts to throttle? is something else tweaked as well? im too lazy to look at the code myself lol

Whose using this? What are you seeing in terms of battery life gain and is the phone stuttering and stalling during usage?

Installed it several days ago. Noticed that charging fell to a crawl, to the point I thought my charger or cable was bad. Uninstalled immediately.

No lag, stuttering or freezing. No issues with charging. Temperature stays lower than normally, for example while using chrome or other browser temperature used to spike up to 60-65° within few minutes but now it's down to 50-55°. I didn't notice any change in battery life.

I'm also curious to know what performance gains or battery efficiencies Pixel phones have with their 'clean' software.

5 second delay in the camera app when changing from photo to video or changing from back camera to front...

@fenibook , can you add any conditions to the module so it's inactive when the phone is charging either reorh cable or wirelessly?

For me camera works fine. Also, installed again on QPR3 and charging seems ok.

Yes my bad.. It was the one plus hide navigation bar module I used.. It was the only one that worked fine with android 13.. Does anyone know a proper one to hide that pill bar?!

AOSPmods, works fine for that. Some of the stuff is incompatible with 13 QPR3, but hiding the pill works fine.
