Im using zaiben rom on my lg optimus 4x hd. The performance is poor. Overall laggy and horrible gaming. I dont like using non stock based rom as they always have some bugs. I tried custom kernel like iodak werewolf but it made my phone heat up like crazy and unusable while charging. Any solution?
Buy another device stock Roms won't give you a good performance increase.

I used stock with zaiben kernel for months, uninstalled all the useless system apps with Root Uninstaller, including hangouts, gmail, maps, youtube ... and then installed them again as normal applications and used the greenefy to hibernate most applications, never had a problem of lagg or excess heat. Now I'm testing some KK ROMs , and do the same thing using iodak kernel 9.95 and I'm liking the results.
Make a bakcup and test some KK ROMs.

Believe me, if you're using an LG phone, custom ROMs are ALWAYS better.
Stock ROM got too many bugs and I don't really like modified stock ROMs as people usually add more bloatware.
You should really give CM11 a try.Latest nightlies got very good performance with iodak 9.5 kernel.And no important bugs you should worry about.

If you use a custom kernel like iodak or ww, you can tweak many parameters. Among them there is cpu clock frequency and voltage.
Personally, I've set the stock 1500 mhz frequency and undervolted Mpu and cpu respectively by -30 and -75 mV. My phone runs smooth as silk and never gets horribly hot.
The guys who replied before me are right, though, stock roms or their derivates cannot be compared with CM11 in terms of performance they are way better. If I were you, I would flash one of the latest nightly and a custom kernel.
After some trials and errors you will be able to find the correct balance between over/underclocking and undervolting.
That is, if you are willing of doing some experiments. If you are looking for pre-cooked solutions I am afraid you will be deceived.

Trickstermod is a favorite for most of the people.Check your tegra variant, if it's 1 or above, you can use -122mV for CPU with no problems, max freq set to 1.5 ghz
I'm using this for months now and I sometimes forget my phone can get hot, unless I do heavy gaming for 30 mins or more.
Also try to overclock GPU.Helps a lot with FPS issues.
If you want good battery life and decent performance, underclock to 1300 mhz and undervolt by -122mV (if your variant is 1 or above)
Btw you can check your variant via /sys/devices/system/cpu/cpu0/cpufreq/tegravariant after installing iodak kernel.Higher the variant, the higher you can overclock/undervolt.
@UP
My tegra variant is 3 o.o But when I undervolt 30mV on CPU and 75mV on MPU - as @peppethustra recommend in http://forum.xda-developers.com/showthread.php?t=2761923&page=2 - it causes freezes, even when I underclock to 1,3GHz :/

All phones are different you may have to tweak the values to fit your needs. Try upping the LP CPU voltage to -10 and work your way down. For MPU try -25 and work your way down on that as well.
Mine is a variant 2 and can use -20 and -110 with the 520 GPU overclock
Edit: also for more performance try changing your minfree values. Lower values mean better multitasking and high values mean more killing of background apps but more free ram for the foreground apps. I personally use 8, 12, 45, 65, 95, 165

Greetings,
This driver is obtained from Qualcomm's 07 Aug 14 drivers for "Qualcomm Adreno 3xx GPU on Nexus 4, 5 & 7 devices running Google Android 4.4.4 KitKat".
All credits go to the folks at Qualcomm for making the developer version of these lib files available for us to play with.
This is for testing purposes only. Please don't flash without backing up first and then start screaming if something happens to your phone!
The package only contains files for Adreno 300 and 330. I cooked the packaged to be flashable on our SM-G900T or any SM-G900 with the Adreno 330 chipset.
I'm on a "XtreStoLite_G900T_ROM_v1.3_UVU1BNG3" ROM, which is a super clean/slim version of the stock rom. This is also Android 4.4.2, my AnTuTu benchmark results dropped from 37400 to 35800 after flashing this package.
I'm requesting someone with a KitKat 4.4.4 ROM to test this and report back their before and after benchmarks.
I appreciate your feedback,
Hmm, interesting.. I'm only on 4.4.2 or I would help out..
Turned out the 3D performance on antutu version 5 with this driver puts our phone one head and shoulder above everyone else!

And this means....... I'm sorry but I don't understand the purpose... Is this supposed to make Tw snappier?
Thanks in advance!
It is updating the video (graphics) drivers. It probably improves the touchWiz performance as well (don't have evidence to support this), but what i noticed was a huge performace increase in the 3D graphics score. This will make games run alot smooter and more efficiently.
To clarify, this file resembles how your Mac/PC has a video card with say NViDIA or ATi video cards and they have their own driver releases. Our phones graphic chipset is designed by Qualcomm and it gets its own drivers as well. Hope I answered your question, and didn't make it worse!

In order to get any real "TouchWiz/Nova/Apex/etc" performance increase from it you'd have to flash this, then venture into Developer's Options and enable Force GPU rendering and Disable Hardware Overlays. And even then our device is so performance driven that you likely would likely not even realize the difference other than giving the CPU a break for a few cycles and possibly seeing a battery life increase depending on whether the CPU or GPU pulls more juice. These drivers are largely made to increase the 3D performance of your device when gaming and while it wasn't meant for us I'm glad to see someone took the time to let us benefit from it.
I'm going to flash it on an NG4 (4.4.2) release and see how it holds up to GPU rendering no hardware overlays. I don't game so if you want an objective test on that someone will have to pick up my slack. I'll report back when I know if it truly impacts it.
Tried flashing the update and ran into a couple random fcs for a few apps. Nothing device-breaking or anything, but I also didn't notice any real difference in performance or framerate in games. But I do appreciate you posting this, I'm always up for trying a little experimentation on my device to find something new. Thanks man.

Don't worry, I didn't forget about you. It takes a few days to really put it through its paces. But here is what you want to know: It works in 4.4.2 Touchwiz (Alliance Rom B4 for me)
Performance Increase in ROM function and control with "Turn Off Hardware Overlays" and Force GPU Rendering: Check
So I tested this by underclocking my CPU to the point where lag was perceivable in things likes app launching, keyboard typing, app draw opening, etc. I dropped it down to about 1200Mhz on all cores and then disabled HW Overlays. It was night and day. After the GPU took over rendering my CPU clock speed hardly moved all of the items previously lagging went right back to being fluid.
So does it help with Rendering in the ROMs? Yes, it definitely can.
The other concern people have is with battery life that goes with GPU rendering and the claims are that the GPU uses more power than the GPU. In my preliminary testing, what I noticed was lower overall CPU temps while Hardware Overlays was off, lower CPU clock speeds since it didn't need to render apps, and a small decrease in battery life.
In the power draw category I need more time with BetterBatteryStats and I need to adjust some variables. I want to underclock the GPU to the point of perceivable lag (if that is possible) and then I want to adjust the governor with KTweaker and see if I can't get better battery life. I will simultaneously lower CPU speeds to keep my core temperatures down and keep the battery cool. If these things are successful and battery life is interchangeable between the two, I may run the GPU full time for rendering the ROM. Keep in mind though, only custom kernels allow this kind of tweaking. If you use a stock ROM you are stuck with CPU and GPU clock speeds where they are so battery will drain faster.
Give me about a week to test my theory on this and see if I can find an equilibrium for CPU and GPU temperature and speed. I'll post the profile I used with KTweaker when I have my results. Until then, if you want to help and find your own settings and post them here along with battery life that would be awesome.
Edit: For what it is worth, to test application launch speeds and UI fluidity with the GPU I completely turned off system animations, I set Nova Launcher Animations Speed to Faster than light and scroll speed to "Fast" (personal preference). I got the same, or better response time using the GPU to render the UI.

I haven't tried it on CM yet, I'm about to flash the 09/04 build of CM11 by Albinoman with KT's kernel. But I won't flash these drivers prior to running the build 24 hours or so to make sure there aren't bugs that existed before flashing the files. So, if you've been running CM for awhile and want to test this build just nandroid, flash, and report any issues.

Ooo that sounds like a killer combo cm + kt kernel + adreno update = project slip n slide lol nah but I'm really curious of what results you might get [emoji4]
And once I flash this, can I go back or will it erase the update once I flash a different rom?

I'll keep you posted. I wasn't impressed overall with it's performance in Touchwiz on battery life with the CPU underclocked, so I am branching out to a more AOSP-like build. I'll keep you posted to what I find out.

Now imagine that's without kt kernel just stock kernel, I'm on xtralite 3.5a t-mobile, so what if I flashed the kt kernel AAAAND the adreno update.... would my phone explode?!?!

You guys make me sad. Benchmarks are not now, nor will they ever be, an acceptable means for telling you how capable your device is. Your scores in AnTuTu are about as capable of telling you your phone's speed as your ESN is at telling people who your phone belongs to. It is just arbitrary numbers that will fluctuate up and down based on the slightest inconsistencies.
Drivers, just like in Windows/Linux/Mac, are meant to optimize the performance of your hardware. That's it. This driver likely optimizes the GPU cycles to make it more efficient and lower heat output while performing better in games. You know why hardware review sites start out with benchmarks saying what it can do in a perfect world but still ends the review by telling you it gets 75 FPS in Borderlands 2? They do that because while synthetic tests are nice, what would be the point if our games don't play better? It is the same concept here.
I'm begging you, uninstall AnTuTu, re-install your favorite mobile game and just base performance off of whether it plays better or not.
Side Note: Drivers didn't appear to do anything in AOSP CM11 when I gave it a try. Sorry I am so late on reporting in, college takes up a lot of my time. Also, using the GPU to draw your applications does eat more battery whether you use these drivers or not. So there is no marked improvement from lowering CPU speed and using GPU only to render.

I figured since the OP stated he got less points in Antutu, I would go ahead and use the same app and test to compare...
F*ck me right?
Regardless, I don't notice anything different either, my stats are in the sig.
Can anyone explain to me what is better?
I know that underclocking reduces cpu frequency, which means lower temperatures and also better battery, but performance is worse, so it takes longer to complete tasks...but if it takes longer to complete tasks, it means it will also have screen on for a longer time right?so it saves power from the cpu, but keeping the screen on for that extra time also means it will consume extra power right?
About undervolting, is it better to undervolt or to underclock when it comes to battery life?i know that with undervolting there is less heat produced because of the reduced voltages. From what i have read (i dont know if it is correct) the power consumption is given by this equation: P = f*c*(V^2) where f is frequency, c is capacitance and v is voltage. It makes sense that reducing voltage means less heat, but if i reduce CPU frequency it also produces less heat because it reduces power. Most of the time i read that underclock is better for battery because it uses less power, but like i said earlier, it takes longer to complete tasks and in result i have to keep the screen on for a longer time.
About hotplugging, i have seen some users with good battery life screenshots, and mentioning that they disabled hotplugging, because they said that turning cores on and off also wastes energy. So is it better to hotplug or not?
would really like to get some answers because i know nothing about this..I also know that i could test each setting and and see which is better, but i dont use my phone the same way everyday so its kind of hard to determine...
Short version and after extending testing (2 cores max, -175Uv, underclocking at 1000 or 1300mHz) with different kernels and always on stock Rom,
the result was that there was no noticeable difference at the battery life with a normal setup of using of 4 cores at normal max freq of 1512mhz.
A custom kernel in comparison to the stock kernel makes more sense cause of the optimization they offer for performance and battery life.

There are different hotplugging methods.
The stock one as a boost feature, as soon as u touch the screen ur decvice goes to dual core 1026mhz for a couple seconds even if the load is super low.
Custom kernels have many variants on the hotplugging "style". Most of them dont have the touch boost included to save battery (but u can have the same kind of touch boost enabled by the governor, ex: franco kernel). Others simply advise u to turn off hotplugging == less calculation of the load to decide if the device needs to plug it or not + no waiting time to get the performance boost of many cores online (since all 4 are already online) + somewhat more heat since all cores are allways draining battery.
Im no expert and i hope all i said is right, at leats its what i know.
What i personally look for is:
Min core 1
Max cores 4
No touch boost (no heat while u are simply texting via sms on 2G with data and wifi OFF)

actually touch boost and hotplugging are different things...touch boost is a feature where as soon as you touch the screen, the cpu ramps up the frequency to the specified touch boost frequency. Hotplugging is a different thing, where cores of the cpu are turned on and off when the phone does not need them to be on all at the same time. I know that touch boost drains more battery, but i dont know about hotplugging...would like to see some tests/benchmarks, but i dont think there are any...

Different things but on stock kernel touch boost is implemented on the hotplug and not the governor.
Any difference btw 4 cores online or hotplugging must minor, and have draw backs on heat wich affects the battery capacity.
Eventhough u can say that hotplugging may drain an amount of battery to plug and unplug cores, i would say its minor.
Talk to @simms22 , he is the "trinity kernel guy", four cores online is a must for him

From my experience, under clocking as well as running a 2 core setup doesn't change anything for the better. Most times for the worst due to a worse user experience.
Undervolting is something that, solely from the physical side, cannot make things worse (unless you under clock too much). Undervolting will make your CPU cores use less current. Less current running through an electric circuit always means less heat, too.
To put it simple:
If my regular voltage at 384mhz is 950mv and I lower the voltage to 800mv and after testing it proves to run stable my device now uses 150mv less on that frequency.

If my regular voltage at 384mhz is 950mv and I lower the voltage to 800mv and after testing it proves to run stable my device now uses 150mv less on that frequency.

no matter what you do , its still going to be a mediocre battery life , best leave it as it is because the way nexus 4 is designed its still going to be getting annoyingly warm on games
Well, from my own experience undervolting definetly reduced heat and made the battery last longer. Don't expect 2 hours more sot, though. Its most notably while the device is idle.

nice man
very helpful...
Help pls..
Can any1 help me undervolting Unleashed kernel.. providing tips or the link ll be vry helpfull..
This is an outdated device, but since SD801 is so efficient, I gave it a try.
Warning - undervolting is a risky process. It may constantly crash your device, make it unusable or you can actually lose all of your data. Be aware.
So, after reading various articles about CPU binning concept, I thoroughly examined my device's potential. Note, that every device is different, regarding CPU quality and etc.
Anyways, I am running stock rom with Boeffla kernel. I actually gave up, when my device was getting hot - I don't like that at all. Since thermal throttling is really aggresive, I wanted to get away from that completely. And I did.
Currently my phone is heavily undervolted (by 0.1V to be exact) and to be honest, CPU temperatures now never ever exceed 50ºC. With stock voltages, I could easily reach 80ºC.
Anybody else tried doing undervolting? Share your experiences. I would greatly appreciate that.
what is the benefit of it?
does it give a better battery life............?

The only real benefit of undervolting is to reduce temps. Even so it isn't recommended because of the risk of instabilities.

lower temperature = lower power consumption = better battery life.

Not necessarily. In my experience in kernels, undervolting only brings marginal power savings. Most battery drain is from open apps and from the display.

Wake locks play a big role too I always turn off as may features as I can on my s5 verizon and settings database editor App to turn off more features than normally possible

Not exactly marginal from my experience. It also depends on which frequency CPU is running. At higher clocks, lower power consumption is more noticeable than on lower frequencies.

Well, that's not quite the same as what I was saying.
Different CPU frequencies use different current levels which will affect the power draw. So in this case, it will affect the battery savings. Whereas undervolting alone doesn't bring much of a difference due to the already efficient design of our SOC (well, at least in my case ).

Undervolting -> Lower Temp -> Less Throttling -> Better Performance with slightly better battery life.
Sent from my SM-G900F using XDA Labs
Throttling is really noticeable with stock voltages. Play some games for a while and you'll start to feel that phone is getting slower and hotter. Not the case anymore after undervolting. If your phone can handle upto 0.1V undervolt, then your SOC is in good shape.

i can confirm this, i feel my phone is really snappy now and slightly worm, not hot anymore
I use 300-2000Mhz and heavy UV 620-850V. I also use "use_spi_crc=0".
After phone reboot on stock i get 80'C (cpu tem module in xposed) and on my settings it is not reaching 60'C
What about battery life? it needs long testing, i can assume that its slightly better because less energy is converted in to heat
There seems to be some misconception on undervolting.
In theory undervolting should translate to better battery life. However....
Real world results tell a different story as it shouldn't really make much difference at all. For example, not all S5 phones run the same voltage tables (different CPU quality require more/less voltage), yet they achieve the same battery life. So what voltage was set by the manufacturer (Samsung) is already the optimum voltage.
You will definitely achieve better thermals after undervolting, but in the custom kernel world, most kernel developers will not be able to provide help in the case of instabilities. Some kernel developers may not even provide undervolting support because there just isn't a great enough benefit other than improving thermals.

What about undervolting Busses, Image processing System, MMC Memory, GPU and CPU?
I`ve got the exynos variant of the S5. I undervolted to -85 all of that stuff and the phone now doesn't heat at all and battery life isn't that amazing but it is noticeably better

I'm using the snapdragon variant with boeffla kernel so only the CPU is allowed to be undervolted.
Undervolting other components alongside the CPU will make a more noticeable difference in terms of battery savings. It still isn't recommended by many kernel devs as these other components are more sensitive to slight voltage changes (including the bus).

Yeah it actually makes a slight difference in battery life, But I don't think anyone should go below these values since I started to get Screen of death and all that kinda stuff that happens when phones are very undervolted haha
If there's a kernel that allows users of Snapdragon phones to undervolt that hardware, I really recommend you to do it, it really helps battery's performance if you need that extra hour of Screen On time
Now, all of this changes are not recommended cause there could be problems with your phones if you're not sure bout the parameters you're playing with.
does anybody else have problem with gpu oc ? no matter what settings i use there is no performance increase at all, its like the 600Mhz is permanent even when all monitoring programs show 700-800Mhz :/ I have tested gpu many times using 3dmark - always the same fps (600-800Mhz). With 200Mhz increase in frequency it should be significant increase in fps!
Hi, I have a one plus 3t and I would like if someone knows a configuration to play, if it exists or something.
Thank you
As long as the Kernel does not underclock your CPU/GPU for Battery Life, any Kernel/ROM should be fine.

That's what I would think. The hardware on this phone is killer. Only bettered by Snapdragon 835 phones (or the upcoming phones for this year).
I wonder if the top poster is having a specific issue with games? Or just looking to tweak/overclock, despite no real issues?

I'm guessing the latter. He's probably on Stock, and he just wants to know if there's any possibility on increasing Performance in Workloads/Games. Nothing much else.
If he does want some recommendations, Caesium Kernel or ElementalX paired with Stock or a highly AOSP based ROM like NOS should do well. Not that the other Kernels or ROMs will be much different, this is just my experience.

right now I am using the z-unleasht, it runs well the games but it was out of curiosity if there was some configuration of Kernel so that it does not drink so much battery and render better
You should try helix engine: https://forum.xda-developers.com/oneplus-5/themes/app-helix-engine-v1-0-beta-3-t3745746/
Then use "AKT balanced" (change in settings). You can choose for every App other profiles -> change it to performance for your games.
Then you have a fast smartphone with great battery life, and performance while gaming.
You need to be rooted

It's not possible to go after battery economy while wanting to perform heavy duty tasks.
It's either one or the other.
Unleashed by my rooted OP3T on 8.0
thanks for the app i am researching to have ..
Hi guys, i have tried many custom kernel such as ElementalX, Flash kernel, Boeffla, Blu_spark, Wolfram..... etc and I still find that my OnePlus 3T can't handle big games..... unstable FPS even at low settings.... and It heats up pretty quick and render the CPU to lower its frequency, etc.....
