Hey guys,
Ive been using SetCPU since it was fixed for the sensation. I am curious about what others have observed as far as battery life and performance goes.
I am running 1.8Ghz with a cpu voltage of 1.265V (1265000uV).
My battery doesnt last all that long despite all the profiles I have in place. I guess thats expected when you overclock by that much, huh? Is it worth it though?
Im sure more of you out there have experience to share. Im not talking Quadrant and benchmark scores, Im talking REAL use!
I am beginning to feel that dropping the frequency down may be in order since I cannot find anything that needs 1.8Ghz to work on this phone. Plus, less frequency means less required voltage. That would mean more battery!
Anyone care to chime in with their overclock frequency + voltage and experience?
Matt
I'm also interested in getting some input from other users, without having to clog up the respective overclocking threads in the Development section.
Yesterday after work, I set up the 1.5Ghz Undervolted option using utking's tool (http://forum.xda-developers.com/showthread.php?t=1168707). I didn't see too much need to push my CPU too hard, and a stable UV always piques my interest.
I created a couple of basic SetCPU profiles (screen off, battery below 20%, temperature < 50C), and scaling on demand up to 1512Mhz, my phone took about another 7-8 hours of moderately heavy use (Navigation, Maps, Yelp, photos, etc.) before it was on its last legs.
Bear in mind that I've been using the Anker 1900mAh battery. But even after the OC-UV that I set up, this was at least as good of battery usage as before without any SetCPU or overclocking, and actually seemed to be a little bit better to be honest.
I just dropped down to 1.6Ghz @ 1.26V...
I couldn't keep my phone from freezing with anything less than 1.26V @ 1.6Ghz. We will see how this goes for a few days and compare to my previous 1.8Ghz @ 1.265V.
So far, speed seems to be FASTER than 1.8Ghz. My Quadrant score (only being used here for comparison reasons) was 2700 right off the bat, whereas 1.8Ghz would peak around 2700-2800 after several tries.
The carousel works much better! I can swipe through quickly and have it scroll with zero lag. I can also fast swipe and watch is spin nicely!
Google Earth and Maps is about the same as 1.8Ghz.
Before, at 1.8Ghz, I could probably get 16 hours out of my phone with VERY LIGHT use. (A few 2min phone calls, check mail throughout the day, check the web a little). I am charging the phone up and will report back later.

I went down from 1.62 UV to 1.5 UV,because I could not see any difference in general use nad in benchmarks(except Quadrant) and battery consumption is much bigger with 1.62 with exact same profiles on setCpu.I think that this is best compromise between speed and battery life and as far as I know this is native clock speed of 8260 Snapdragon.

How simple is it to temp-root and overclock? I am really only interested in overclocking to speed up Sense, and you said it performs better with a speed boost.
Sent from my HTC Sensation 4G using XDA Premium App
Very,very easy,just read this tread :http://forum.xda-developers.com/showthread.php?t=1168707
I have mine undervolted at VDD_1175000 and 1500MHz. I like it very much...makes a big difference in quadarant score, but not sure in reality how much faster. Battery life is fine (when the phone is on). Have not experiened FC's
I have modified eugenes batch file to push my kernel file and preferred speed after perma-temp-root and now is all in one click...
So here is a little update:
Its been about 8 hours since full charge and I am at 55% battery left.
1.6Ghz @ 1.26V, On Demand.
Ive been checking email, making a few calls, and surfing the net with both wifi and GPRS (was out of the network, away from 4G). I also played Angry birds for a little bit and showed off Google Maps and Earth to my Mom.
Now that Im back home, ive turned back on 4G...
Ive noticed a slight amount of hesitation while opening and closing things, but nothing bad.
I havent had any profiles kick in yet, but they will soon with the battery getting low. I will resist charging the phone and see if I make it through the night, using it as I need it. I will report tomorrow.

I must be doing something wrong.
I am rooted and running LeeDriods 1.2 Rom. When I launch setcpu the only options i have are 1000 mghz? WTF am i doing wrong?
i think at LeeDroid 1.2 you must not use setcpu but Demon control?

Hmmm, okay. I saw where set cpu was updated for the sensation in the latest release but it doesn't seem to support overclocking with this rom.
Shame that as i was about to get that rom and flash it onto my phone, glad i came in here now
Running Leedroid 1.0
Kernel @ 1.7ghz max, i have it set to 1.5ghz and 192mhz
Runs hot when i play finger racing or reckless racing or modern combat 2 or something intensive, but besides the heat, it drains just like it normally would to be honest, maybe a little quicker, definite speed increase in overall user experience, without an OC the rom just flops, better than stock but just crap, OC is needed.
Is there any particular reason the second core always drops down to 216mhz? This happens with any custom kernel I run, currently running moray with electra kernel at 1.5Ghz using pimp my cpy to OC.

when it's needed, it goes to the required frequency...
sounds reasonable but I will notice some lag and stuttering while I am using the xoom, i will open os monitor and the second core is sitting at 216, i move it manually to 1.5Ghz and the tablet is more responsive...
Edit
Sorry I should have been more specific about the situation. When I say the 2nd core drops to 216 I mean the max frequency drops to 216 so the 2nd core does not clock up any higher unless I manually intervene.
same on my xoom with tiamat 2.2.2 and setcpu. i have two profles , screen off with 216-456mhz and other with 216-1200mhz. only the first score is over clocked after switched on, the second stucks at 216-456mhz. i contacted the developer of setcpu someting around 2 weeks a go, but no solution till now.
okay i see wat u mean...i just checked and i'm getting the same results... it sits on the min freq, all laggy, then when i manually set the frequency, it's super responsive like it shud.... i'm over-clocking to 1.6 btw

I don't think that it strictly a SetCPU problem. I also have an Advent Vega and have used SetCPU to overclock it. Had almost the same problem, except both cores were stuck at 216Mhz.
Tried multiple overclocking apps and have had the same problem with all of them. Device fine until it goes into sleep mode, CPU stuck at 216Mhz when brought out of sleep. Even setting the minimum setting to 456Mhz still resulted in the CPU being stuck at 216Mhz on wakeup.
so i guess the big question is whether it is the kernels (I've tried a few) or in the way these apps OC a dualcore processor...It makes me wonder about the OC apps though, they were all built for single core originally and in each of them you only set 1 max and 1 min speed. OS monitor is the only app that displays both cores, at least that I have used, but it doesn't set an OC value at boot. Maybe if one of the smart devs on here could comment maybe even just to shed some light on this
Is there no solution to this issue yet?
Is it a tegra fault/problem?
Is it a Kernel issue?
Would flashing back to a stock kernel fix it? (if that is even possible...)

Seems to be a nice idea. But could you elaborate as on why the text is bold and you had to use capslock for 1/2 of it!?
@slind ok i fixed the post. i will be posting links to the posts who are great battery savers without loosing performance
So basically, we use an I9500 like an Ace or a Grand to get rid of heating and battery drains.. Andyou suggest that it won't result in performance loss. I'd suggest playing games that are more graphically intensive and not just Temple Run.. Try copying data from one memory card to another, or simply try running a Full HD Video. Also, check out web browsing or maybe multitasking, and you'll see where the performance dies out.
I think the fix should come in the upcoming releases of stock firmware by Samsung. By turning off a couple of cores, you're only going back a couple of years. I don't think I upgraded from the S3 to S4 for that reason.

everyone has there preferences and there needs in a phone. and there own settings. and this is a Battery discussion thread. we will be doing many performance and voltage mods, so everyone could choose the settings that suits them. now please dont post aggressive post like that, im not stupid. i know that my settings are very low.
but for my most played games and most used apps. it doesnt seem to effect my performance, so im comfortable with my settings
i had the phone for 2 weeks, happily showing off battery performance and then i asked myself again, why the heck i bought this phone in the first place? BECAUSE IT HAS REPLACABLE BATTERY!.. LOL.. how silly i am trying to squeeze that little drop of power out of the battery when I can double the battery just by getting another spare.
no need to turn off anything, no need to drop performance or screen brightness.. just pure enjoyment of the full potential without worrying battery problem.. just get a spare.

I didn't mean to be aggresive and sorry if you felt like that. All I mean is, there is a limit to which you can undervolt/underclock your phone without losing the functionality or speed. While underclocking to 1.0 ghz or 1.2 ghz sounds kinda normal, going all the way down to 800 Mhz and that too only on two cores is like running Galaxy Ace Dual Core instead. Why would I want to spoil my S4 for it?
That is all that I meant. And the phone is normally shelling out a good day's use in normal usage. Why bother so much about battery really???
My S4 i9505 came with MDE ROM from the factory, apart from doing dirty flashes over dirty flashes, finally someone came up with a recovery which is working. So i've :
1. Formatted system , cache , dalvik
2. Loaded in Djembey's stock slim deodexed ME2 ROM.
3. Using PimpMyROM, did some moderately less aggressive tweaks.
4. Capped the Max frequency at 1674MHz. Interactive gov, Noop sched.
5. Fully charged and unplugged.
6. Fully on 3G . Gmail sync for calendars, contacts, mail, keep, notes. Moderately heavy on Gtalk and Whatsapp. Browsing news and websites.
Observed 4 hours screen time.
Almost 15 hours of total usage + standby (This doesn't mean much, screen time depicts usage time more)
The phone still feels warmer than S2, under operation.
I've yet to try faux kernel yet, but i doubt it would get much better than this. The physical limit i feel is on the CPU, HD AMOLEDs, and the modem itself under normal usage.
Feel free to comment.
Hi,
hope you may be able to help. I have been trying almost everthing to increase the music volume as the s4 does not drive my senheiser headphones as well I would like. Is it possible to increase the gain through a kernel mod somehow?
Wow you're really random. This thread isn't even remotely discussing about the issue you raised.
Try the omega ROM thread, see if the functionality list includes volume hack.

Hey guys!
I've been experimenting a lot with my S4 and I figured out why many games lag...
The reason is that my gpu clock drops from max clock I set, to 320mhz once the temperature reaches 68C!
Some may say, this doesn't happen because the gpu doesn't thermal throttle on the S4 like on the HTC One...
Well...I used performance governor which is supposed to keep the gpu clock to the max at all times, and guess what?
When the temperature reached 68C my gpu clock went down to 320mhz even with performance governor!
How is that possible...?
Performance governor can't throttle down!
Thermal throttling is to blame. (or something else, that doesn't care about governors? )
It's not a coincidence this happened at exactly 68C like before.
(If anyone wants to argue with me about this I'd appreciate if he/she doesn't spam my thread for the love of god and pm me.)
Anyway, enough with the prologue..
This was a royal pain in the ass for me because I almost regret selling my silky smooth S3.
After tons of random searching and messing with the system of my phone I found the solution!
Here it is!
Sell your S4!
Nah, I'm just joking!
It's a great phone.
Here's the real solution:
I set
/sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/min_pwrlevel
to 0 out of curiosity, which controls the lowest power level, or clock, that the gpu will use.
By default it's set at 4.
Since max was already 0 which means it's the highest value I set min to 0 too, and guess what?
The gpu clock remained at my set max, 504mhz, all the time, even after 68C!
Tried three games I know this problem happened and all three worked at 504mhz!
(for pure information, it was Modern Combat 4, Gangstar, and Asphalt 8)
How can you try it?
I've attached two scripts, one that sets the value to 0 and uses max gpu frequency all the time and one that sets the value to 4 so that the gpu can use the lower clock states again!
For Script Manager Users, free
Use script manager as root to run these widgets and I'd recommend you put two widgets on the home screen!
One for the first script enabling this tweak, and one for the second that disables it.
For Tasker Users, need to pay
If you have tasker you could use it too and set it to run the content of the first script as root at every heavy game and enable the tweak automatically, after that use tasker again to run the content of the second script when you go to your home screen (or anything else you want to set) and disable the tweak automatically!
Beware!I will not responsible if you damage your hardware!
Recommended prerequisites:
- Custom kernel preferably ktoonsez's or ausdim's, but any kernel with undervolt and thermal throttling control support will do.
Increased heat may be produced after doing this, so I recommend you to undervolt at least a little to reduce the overall heat, plus increase the thermal throttling limits too to prevent the cpu throttling down.
I use 85 as start limit and 82 as stop limit but you don't have to use my values.
I just find them safe enough and high enough so that they don't interfere with my games.
Try it and report back, many games are way smoother now, at least for me.
I'll be waiting for your results!
Have a nice day guys!
P.S. If you need to tune even more your device, take a look at my personal settings found here:
http://forum.xda-developers.com/showpost.php?p=45103847&postcount=1106
The gaming profiles are set at 1242mhz min now, not 1458mhz like before, because the gpu clocks work properly now the cpu doesn't need that much boost to avoid lag.
And the gpu clock I use now is 504mhz instead of the stock 450mhz in the link.
That's it!
You said that the gpu clock remained at my set max, 504mhz, all the time, even after 68C, but you didn't say how hot it got.
Did it get hotter than that? I'm a bit wary of frying the board to squeeze out a few extra frames on my device, but that's just me.
Haw much does it take you to reach 68° ? I have the 9500 version and i didnt face that problem yet.. it s going warm but doesnt lag

You won't don't worry.
Both the cpu and gpu have a tolerance up to 100C, plus the system automatically shuts down before reaching critical high temperature.
For me it didn't get much hotter, only a few degrees.
You can monitor the frequencies and temperature with the Qualcomm Trepn Profiler which is an advanced free monitoring app for Qualcomm devices:
https://developer.qualcomm.com/mobile-development/performance-tools/trepn-profiler
or
you can use this app by senior member @rlorange which is much simpler and gets the job done just right:

Sorry but this is not for the i9500, this is the first thing I wrote.
I don't even know if this happens on your device mate.
Anyway, it doesn't take much, play a heavy game for a few minutes an you'll reach 68C.
Updated link with my settings, now it's correct.
Sorry about that.
Is it possible to change this value without a reboot ? Like in a small app for example ?
Hey buddy...juz chk yu are having any thermald file under /system/etc...??
thanks mate!! It's working perfectly
So this won't work with a rooted s4 on stock rom and kernel?
If not I'm returning my phone. I played vice city today and the lag was terrible. I've only had this phone for two days and I'm dissatisfied with verizon and samsung for gimping it and then locking it down.
imo, companies advertising the power of their chips is false advertising when they set temperature throttle so low

No mate, I'm sorry.
But good news is Samsung WILL fix your phone no matter knox 0x0 or 0x1.
(confirmed)
So flash your device and try again!
I must agree, companies are full of crap when advertising their products, it's so furstrating!
This throttling issue happens with any device, including iDevices.
Bootloader is locked. Most likely forever.
Don't have MDK so I cant loki.
Even with safestrap (which doesn't work for my MJ7) you can't flash custom kernels.
This phone is going back :good:
I'm going back to my trusty gnex for now. It would probably play GTA better at s4 resolution because I overclocked it and disabled thermal throttling.
Maybe I'll get a g2 with loki support...
Either way, I would like to give a Linus Torvalds Salute™ to samsung and verizon.
Too bad. :/
Wait for some exynos device or anyone with custom cpu/gpu because qualcomm imho isn't good enough.
I got this to work on my s4. Are there similar settings I can modify to prevent cpu throttling?
Edit: cpu throttling settings exist. But it wasn't throttling... it was changing governer and minimum frequency.
I set the governer to performance with root explorer and it's working perfectly.
Thanks op for the location of the gpu settings. There was no way I would have found it without your post.
I've tested it (works fine) but I have the feeling that somehow the phone is too warm

Glad it worked guys!
Well, the temperature will definitely increase because of the increased gpu clock speed, but as long as cpu throttling temp is <=85 you should be fine.
That's what I've been searching for all day, I knew this device can handle those games, but the random stuttering was painful.
It lowers the GPU to 128 MHz, I measured that when I played Apshalt 8 and got my TricksterMod set in background. When the game dropped massive FPS I switched to Trickster and saw that the GPU is running 128 MHz, shocking. Ktoon's kernel has a touch boost which works nicely but Asphalt 8 is a racing game that uses the sensors to steer and so I did not touch my screen so often and I need that.
You sir deserve a medal.

I knew something was off the minute I started playing modern combat 3 and saw the same performance as my S3.
I researched quite a bit and found this in the end.
I even got in an argument with a guy at ausdim's kernel thread about this because he was saying I was talking nonsense and he wanted proof in order to believe me.
Well, here it is.

Ah, yeah no one can say to me that the games run buttery smooth without any modification.
A game does not run smooth on 128 MHz.
And all those amateur reboot your device and etc... They are complete nonsense.
I want ask a thing before flashing... Is this only an unlock and gpu scales the frequencies as it needs or I have always gpu freq at max on depending on what I'm doing? I hope this only unlock the max frequency otherwise became e battery drainer hack! Tell me guy!

Hey there,
so i have been trying to get my girlfriends A700 on a modern version of Android, but so far stuff like Omni ROM or Pacman ROM had REALLY bad performance. I'm talking about 7-12 fps in the launcher and most other apps, which to me is unbearable. Today i was experimenting with kernel settings, and for this activated the CPU usage overlay.
It showed that 90% of the time only CPU0 is used and all other cores are deactivated and idle. I'm not sure if this is intended behaviour, but in combination with the choppy performance it's kind of suspicious to me.
So basically i have 2 questions:
1) Are all the Android 4.2 and up custom ROMs just really slow, or is there something wrong on my gfs device?
2) Should the device be running on one core all the time?
Mine is quite laggy too (currently on PAC rom).
Did a couple of updates via Google Play Store today and had a look at the CPU overlay. All 4 cores showed up to 1,25 GHz.
No idea how to check the fps though.
