[Q] overclocked kernels and nexus S? - Nexus S Q&A, Help & Troubleshooting

Back with another of my noob questions that is hard to find definitive answers to. Ok so I am running on a 1.4 kernal....is this good for the health of a phone? Now it seems the kernal side of development is really motoring....what can kernals offer ultimately to users? Thanks in advance

custom kernels mostly provide performance improvements. but sometimes they can also enable features that werent available with the stock kernel(for example... 720p video recording and fm radio in the nexus one)

Thanks I understand battery performance can be increased also?

absolutely!

A kernel with cpu undervolting could give better battery performance.

Excellent. Well the benchmarks don't lie and my phone certainly boots up quicker at 1.4. over or underclocked I look forward to more kernal flashings. Modding is a bit addictive

[Q] HTC Sensation 4G T-Mobile US Kernel above 1.5Ghz

Has anyone used any kernels for HTC Sensation 4g (TMO US) above 1.566Ghz?
I am currently using a ROM by Mike1986 and kernel witch took my phone to 1.566Ghz and i am loving it.
However, i am a big OC freak and i would like some pointers on any tested kernels above 1.566Ghz, preferably that work well with Mike1986's ROM as i find them to be most stable our of all i have tried (i have tried 3 different types).
Any input is highly appreciated and welcome. Thanks team.

I honestly don't see the benefits except lower battery life and a warmer device, I doubt you'll notice the speed difference past like 1GHz. All of the higher freqs seem pretty much the same and aren't really worth the bother with, use a governor that accesses higher freqs quicker and you won't be needing high freqs.

What governor would you suggest??? also, i know that when using you phone and maybe even playing games i wouldn't see much of a difference between the stock 1.2 Ghz vs 1.5 or 1.9Ghz but it's all about the bragging rights, lol. I like to go to my geeky friends and slappin’ a higher clock frequency than they have on their poor devices or silly I Phones. Also I have to tell you from my tests I do see Mike1986’s latest 3.6.7/4.1.7 Rom using much less battery life than stock Rom. I have noticed about a 10% improvement, maybe even more.
Also i do see a big improvement in Benchmarks. When i was using stock 1.2Ghz setting i was benchmarking much lower than the 1,5Ghz i am at now.
Thanks again for the input.
The benefit of custom ROMS and kernels, is that they are optimized to run well. Unless the chef sucks, most big name ROMS are optimized and more efficient.
I was running 1.2ghz for a while and whenever I'm playing Snes roms it would FC. After bumping it up to 1.72ghz it never did it again. Although 1.72ghz may be overkill for what I use my phone for but everything seems to be running extremely smooth.

I use conservative(810/192), super charger v6, ultra smooth rosie on 4.1.6. I haven't used benches, but they'll be low on this ROM since I'm assuming it's based on the Sense 3.5 leak for sensation.

Best kernel to keep things simple, stable

I'm really very happy with my Nexus S 4G. It's unlocked and rooted, but otherwise pure stock and I really like it that way.
Coming from the Hero it's a pleasure to have a phone that doesn't require heavy modification to make it perform properly. Still, I miss the thrill of flashing ROM's and kernels.
I would like to try a kernel...mainly to simply o/c a bit, but I don't want it to suffer stable and reliable operation. I recall with the Hero, some of the kernels would adversely affect things like the GPS, making it something I couldn't rely on.
So my question: what kernel can I use that is uncapped, but will otherwise be as close to stock as possible?
Thanks for your thoughts!
Kernels are pretty different over here. I don't even know what's closest to stock. They pretty much all have mods in them. Matr1x kernel is pretty popular. You may have to up the voltage for it if you oc to 14xx. 1200 seemed pretty stable to me with default voltages. Currently franco kernel is pretty popular. You can't oc it, but it seems pretty snappy without oc. GLaDOS is also being used a bit but i've read some mixed reviews and for me at least it did seem a little lagging at times for the short period I ran it. I tried Trinity kernel when I first moved over from the hero and it seemed kind of flaky though it's possible that could have been due to the kang I was running. There are a few others out there. Cm7 kernel has a lot of the same mods cooked in though it's likely not the latest updates. You will see a lot of mention of BLN and Voodoo. There are apps on the market for those features and there's an app nstools that has some kernel config settings you can adjust depending on kernel. Mainly just try to read a lot. Most of the roms and kernels haven't given me any major issues beyond the random reboot, which coming from the hero, just means "normal" lol.

Once you flash you can't stop O_O that my experience i'll direct you to Peteralfonso's kernel on his website here
Searching the forums would help you more than anything. You will get more info by searching, rather waiting people to reply here. These questions are asked on daily basis. And get the same replies everyday. I don't sound to be mean but seriously there is more info than you can get by starting another thread, only thing is you need to dig the info.
I have tried a few different roms and kernels and for once cm7 runs perfect for me w the supplied kernel. No reboots. Has been stable at 1440 performance for testing but I usually leave it at 1000 on demand.
Yeah they all have this blinking light crap in it now by default which I hate, and the lights turn off and I don't like that either. I want the light on when I'm using the phone and off when I'm not, not the other way around!

I like the bln mod, but I do not like the one that turns off the backlights when using the phone. It's just easier to use the buttons imo and gives a quicker visual reference for everything. Otherwise I mostly am left wondering what is up with all the black space.

I hear you on that, and spent a lot of time reading comments and concerns and problems about the various kernels available. They all seem to pretty much be experimental, with various idiosyncratic problems and lots of bells and whistles such as aforementioned BLN, Voodoo, deep idle, etc.
I thought maybe I was missing something in my search for a kernel that would allow o/c, but not have the stability concerns of a the feature-rich, highly customizable kernels.
I think the Matr1x kernel will be your best option, u can OC it till 1400mhz, what I don't recommend to do, but at 1200/1300mhz its pretty stable.
It also got many options like BLN, BLX, Live OC, touch wake, etc.
But if you don't want them, why you just don't use 'em?
Like just flash the kernel and keep it like it is, and maybe do some overclocking.
wanna stable ? stock kernel
basically , there is no kernel more stable then stock ...

True, but he prefers to OC it a bit.

franciscofranco's kernel (link) works best for me. It's fast (no lags even without OC, I'm running at stock 1000 MHz), reliable (I've been using it for at least month and I haven't got any random reboots or application hangs) and battery efficient (thanks to deep idle and other tweaks).

Never found a more stable kernel than Pete's. However, I've been on Glados for the last week or so and am seeing excellent battery life with Deep Idle.

personally i think overclock is totally unnecessary , why ? 1 GHz is sufficient to handle all job you require to the phone...
Best thing to do would be compile your own stock kernel with oc.

True again. I love 1100mhz because it gives you a bit more speed with no lagg, and you batterylife is still awesome.

with deep idle OFF, the difference between the two is minimal, idle stats displayed deep idle has been 0
Downloaded and testing peter alfonso's kernel now. Its very minimalistic, no options like deep idle etc, and u can OC it up to 1400mhz. Running 400-1100mhz for a day now and the battery life is just awesome.

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.
woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw
Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.
Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

For battery life? isnt mdj's kernel overclocked? (GPU&CPU) Stock better i think.
Yes, it is overclocked but it can be lowered to 1.5 and has been tweaked to provide better battery life.
And its also known to corrupt internal storage

But GPU have to stay overclocked
I haven't experienced any corrupt internal storage issues with the kernel. I suppose that is part of the risk with flashing anything though.

You can always flash back to the stock kernel. I was also a little worried that OC'n everything would drain battery like crazy, but I easily get 1-2 days out of my phone. The biggest battery drain comes from the screen. If you're playing a game, browsing the internet, or anything else that requires the screen to be on while using the device... it doesn't matter if your processor is unclocked to 800Ghz, you'll only get a few hours (3-5) of battery life. There is no rom or kernel that is going to fix that.
If you think about it, overclocking the processor will allow you to do things faster and minimize the on-screen time.

Kernel

Hy friends I'm coming from note 3 and I've searched but can't decide what kernel is best for sound and battery I'm not interested in games or something else .I have to say this is so much better that crap touchwiz but on note 3 the battery was good and faux sound rocks .thanks all and appreciate the opinions .overall happy with the decision this is so much better than samsung

kernel wont really help with battery. battery life is all about how you personally use your device, how you personally set it up, what apps you choose to install, and very much the quality of your phone/data signal. all other things are very minor when it comes to battery, including kernel.

If only I had a stock answer saved in my ever notes, that I could just paste in every time.
Oh.... Wait....
"Best" ROM.
There is no such thing as a best ROM.* The question itself is*ambiguous.* "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM,*ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people*are using, you can see which threads stay around on the first few*pages (and have the most posts) in the*Android*Development or*Original*Android Development forums. You can also see what other people*are running by reading the*What*are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device -*they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery*if they have a feature that is badly coded.* You will likely be able*to read about this in the ROM threads.* ROMs do not impact battery*life.* The only impact to battery life are your apps, your settings,*how you use the phone and mostly, environmental issues such as Phone*Signal.
For tips about improving battery life, please read*[Battery*Life Help] Troubleshoot battery issues here!
"Best" Kernel
Also, please note that as above, "best" is still subjective.* What we*all want from a kernel is different. Again, many people have the*misconception that Kernels affect battery life.* Let's get this*cleared up.* Although Kernel devs will build in optimisations and*efficiencies that will improve battery life, these are very, VERY*tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery*life".* This is actually wrong. *Kernels respond to user settings.*Setting up the governor to favour either battery life or performance*is simple enough to do, you just have to do some learning.* The reason*people think Kernel x is better than y is because developers set their*kernels up with their preferred governor settings.* This is what we*refer to as out-of-the-box settings.* The out-of-the-box settings for*kernel x may well produce better battery results than the*out-of-the-box settings for kernel y, which favour performance.* The*fact is, you as the user have the ability to tune kernel x or y to*perform the same, be that battery or performance - so start learning*how to do this yourselves - that way, you can choose the kernel based*on the FEATURES you want, and not the fictional performance benefits*of one kernel over another.
Hope this helps

Use one or the other. You will cause conflicts otherwise. My bet is on Viper.
No conflicts I use fauxsound with quality and viper4android for the rest of the settings the only thing is that I'm using the driver from viper but no problem sound is great I feel that soundstage is better than what I had with note 3
PS : any opinions on sound on lollipop I know that on l we have support for 24bit 192 kHz
