[Q] Disable CPU core? - Samsung Galaxy Nexus

Searched around and couldn't find much on it. Is there a way to disable one of the cores when the screen is off/on? I feel like I really don't need two cores running all the time. Thanks

You could use InteractiveX or Hotplug as CPU governor, they switch cores off when the screen is off
Though from what I saw, and what I read from other users is that switching cores off doesn't save that much on battery... the CPU isn't the biggest battery consumer. If you want to save battery you should dim your screen, it's the biggest battery killer

...since it takes longer to execute operations that run in the background/screen off.

with trinity kernel, and the trinity kernel toolbox app, you can turn off one core whenever you feel like it.

Lol I have Trinity kernel and the app but it won't let me turn it off, my screen is all low all the time. Was just curious lol I use my incredible 2 as a music player and with 5 hours playing music on that it had 75% battery and with my gnex sitting in my pocket with all data off it had about the same.. well thanks guys!

Why do I get horrible battery life with ROMS and Kernels?

I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?

I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

I'm getting about 1.5 hrs screen time. With stock in was getting 2-3hrs. As far as apps keeping my phone from sleeping. I'm running the same apps I run on stock android when I was getting a full day on average so not sure how they would run different because I'm on a ROM.

I had exactly same problem... And on stock no problems
But now... Franco m4 + aokp b37
And 3 to 3.5 hours screen

I used that better battery stats app and apparently there was audio something (sorry can't remember the exact words) causing partial wakelocks, read some google search results and disabled the lock screen sound in aokp and it went away, go figure?
I swear my battery life is better with the kernel that comes with AOKP rather than franco, which was a bummer since I'd just bought the franco updater app, perhaps just my imagination or maybe something just needs to be tweaked
Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery
Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.

Better battery life(get >= 1day)and personal tweaks!!

I'm posting this because all the rom and kernel combinations out there are just lethal for my search ego.This is to tell u guys how i get my one x to move up a day and counting without telling me low battery and with somehow constant use.I'm using the viper x rom(other great roms but this is my personal best)and the faux kernel.(0verclocking latest faux kernel). Thats all.Also u'll like to disable battery percentage as it gets ur mentality off ur use and more on looking at it.
-My trick is i just plugged my phone to the charger at 7pm(low battery).Took it off at 10pm(even though it was full before then).Slept at 12.Woke up the next day till evening it lasted and then one day after in the morning 8am i got 50%.(not really heavy use,light gaming,browsing,opening apps.....).Very impressive.I could use it the whole day again and it will die at night around 7 for cycle to continue.
-This keeps u from overnight charge to 2 days charge and its pretty awesome.
Again u cant use ur one x as a ps3(vita) or gaming console or even an ipad browsing experience and expect it to last u.Sure u can browse but......u know the risk on battery or else get locked bootloader motorollas .
NB:When battery percentage is on u are off focus always thinking of the battery.Just leave a bare battery bar.
Thank if i helped and peace.Hope it works for u.
or flash CM10 which has good overall battery life.
HOX Grey,CID 02_001,Viper x rom,faux kernel and the food is ready.:good:
Can you post some screen shots with screen on time and battery usage please?
Sent from my HTC One X using xda app-developers app
pretty simple what you guys need to do to get a good battery life.
1. make sure you remove auto brightness and set the brightness of the display to manual. so set your own brightness of the display.
2. only sync stuff that are important like emails or whatsapp.
3. if you do not use maps uninstall them as those can be battery drainers.
4. use the latest NCX kernel and use system tuner...use ondemand governor and sio/noop schedulers and keep the clock speeds at 1.2ghz and undervolt by 50 steps...
follow those steps and you should see an increase on your battery...i am using ICJ rom so if you want to go down that route your battery will increase... i always average 3hrs screen on time and battery lasts me a whole day
I know a not of people hate this feature, but I get amazing battery life with the new Power Saver feautere in JB, only disabling it when I'm gaming. The phone runs buttery smooth only having trouble when facing heavy multitasking in which cases I also disable the Power Saver.

Wow, some white-spaces and extra new lines wouldn't kill you, but would read much better.
But let's get to the point: What about your Wifi, 3G, GPS and Bluetooth usage??? And where's the screenshot of the usage when you click on the graph, the details screen?
when i want to use System Tuner or Android Tuner with the Faux or NCX Kernel the Phone is really unstable, setting the Max CPU Freq dont have an effect and the unervolting to -25 mv let´s freeze my Phone. Why ever :crying:
I use power saver mode on, lower auto brightness mod on latest ordroid and setcpu with a few profiles and I get around 24 hours with heavy use.
Not sure if setcpu has any effect??
I set the max freq to 1ghz unless I am playing a game.
Also set max freq to 640 when screen is off.
Does setcpu work under JB Roms??

Download CpuSpy and check the frequency's your phone is running at. If it shows over 1ghz then Setcpu hasn't worked

if you didnt happened to read the article, it only improves performance by continuously invoking all cores at the highest clock speed available on your kernel. this IS NOT a good thing.
" the app is forcing the CPU to stick to higher clock frequencies due to the constant I/O use. For many users, the processor running faster offers a smoother experience at the cost of your battery. As many users began to notice, Seeder was causing otherwise full day smartphones to die in four hours."
I read the article a few times. What I got from it is if constantly on, we will see a significant decrease in battery? So, can this decrease the life of the processor or is is it strictly related to battery performance? If just battery performance, I would give that up especially in the evenings when my phone is on a charger when I catch up on all the forums and rom development or searching websites that run videos or load alot of pictures. I can see not using while mobile but if I have a charger readily available I would run this as I am now and seeing significant differences.

So it lowers battery life and thus you say it is USELESS? How about those of us with spare batteries who want performance and don't care about lowered battery life? We want our rigs to scream and this mod seems to help.
Hardly useless. Better to update your OP to say, "If battery life is your number one consideration then this may not be the mod for you, but if you want to phone to run at it's fastest and don't care so much about battery life, you may enjoy this ..."
Users can turn it on when they have access to AC power and turn it off when they are going to be away from the juice for a while.
there are easier ways of boosting performance at the cost of battery life.
Performance governor does the trick just fine. (or setting min/max to the same clock speed.

That's called the placebo effect. The app doesn't do anything beyond keeping your cpu at higher clock speeds.if you're already doing this, then is doing nothing for you.
Tapatalk is a network intensive application. Whatever performance gains you perceive, are likely due to network issues.

I don't have the Seeder mod turn on by default. The other day after changing out my battery I opened Tapatalk and noticed that it was loading a half page of threads and then hanging. I turned the Seeder mod on and it immediately started loading the entire page. I turned it off and again it lagged.
There is NO DOUBT WHATSOEVER that this mod is making at least certain apps run faster.

i say it is useless because it doesnt do anything you cant already do better. it's being marketed as if it is some new miracle program when it isnt. perseus at 1.8ghz w/ performance gov on will outperform this everyday, simply because the program is writing to your nand constantly, whereas, any kernel overclocked can do this without writing to nand. battery life wasnt really what i was talking about.
i pretty positive the continual writing/erasing of things from your nand is not a good thing and will significantly decrease the life of the emmc/nand on your phone as well as the life of your cpu.
I tried it and It works great on my one. I'm using icy snap 1.5 and it was little bit lagy but now 2x faster than before... :thumbup:

Actually, you don't. Even the most experienced developers can't tell if their own applications are running faster specifically due to any one thing just by running them.
To make a causal connection, you not only need to do proper benchmarks, but also understand why.
The mod does have a side effect of keeping your clock speed higher, which can speed up your device...but if you said you've already set your governor to performance, then the mod is doing nothing for you.
And again, tapatalk is a network intensive application. Whatever improvement you see is much ado with network congestion that anything this mod can do.
...but c'mon, really though...tapatalk is your benchmark? My evo shift can handle tapatalk without lag.
Any lag you see in tapatalk is network related. And any improvement you see in tapatalk is network related.

Oh well. I continue to be amused by the fact that individuals who are not in possession of my phone seem to know better how my phone is performing that I do.
Let me say it again. My phone JUST RUNS FASTER with this mod enabled. Period, end of sentence.
And you claim that SetCPU does exactly what this mod does if I set it at 1.8 performance? But you admit that this mod does it in a completely different way? So how do you know this doesn't add an extra benefit since it is doing something differently? You don't.
You keep talking about how tapatalk is network based and therefore this mod could have no effect. Did you consider that this mod may cause network data to be parsed faster and more efficiently? Image heavy web pages also load faster. The improvement is undeniable.
I promise you I will have sold or thrown away this phone long before the memory gets burned out.

Because it doesn't. It didn't claim to do that. It claims to do one thing and thing only: it keeps /dev/random primed. Read the description of the app.
As a side effect, it keeps your clock "awake" and at a higher level. This is equivalent to switching to performance governor...but doing so in a manual way. (Less efficient way)
I think that's the problem with your over confidence. You are so sure that it's working...You don't even understand what the app does.
And the app definitely has no effect on memory management. Priming /dev/random will do nothing of the sort.
Also,You may not have noticed, I have the same phone as you. Of course, it's possible the app doesn't work for non-believers.
Yes, I know your next argument...it's not placebo because this makes things just seem faster.
I can't argue against that logic, but causality is definitely against you.

Battery depends on how you use it. Usually some custom ROMs can help save battery life but it has been proven by a lot of people that Touchwiz has the best battery life, but really there is a small difference since the phone averages 4 hours of screen time. :silly:

My battery life was always best on stock 4.1.2....heavily debloated, greenified and location, sync, GPS all off...and screen kept as dim as I could use.

Lux is good to control the screen brightness.
Also I always rebooted after unplugging from charger. Otherwise I'd sometimes have problems getting deep sleep.

Dude, if you want to just increase battery life with Jedi, I'd say find Cl3kener's last 4.1.2 Tiberius Kernel and flash that. Install TricksterMod from the play store. From Trickster change your scheduler to bfq and your governor to Ondemand. Turn minimum CPU frequency down to 192. I also turn down my GPU max frequency down to 177, and my mpdecision idle_freq to 192. You should definitely some increase in your idle battery consumption. Unfortunately there's not much to do with active battery consumption like games and video .
I used that rom for 6 months...(I stopped using it, because I started to hate touchwiz), and I didn't have any problem. It's probably going to work for you too, but just in case, take a backup. (Remember that you have to install a custom recovery)

battery runs out fast while using phone

hi all,
I recently switched from stock rom with root, to pure nexus rom and ElementalX kernel.
the reason i changed the stock rom is because of battery drain while phone is asleep.
the wakelock detector showed that the play store and google services kept it awake.
now the awake percentage is much better, but it seem like the battery runs out faster when i'm using the phone.
the battery can loose 1% an hour asleep, but it seem like every time a touch the phone it looses its power really fast.
does it make any sense?
should i just admit that the 5x battery just isn't enough for me?
i'll be happy to hear you advice,
thanks
I agree phone does drain fast whilst using the phone I can't get a full day of use with this compared to the iPhone 6 I had

Maybe you guys need to look at some of the apps you run? Facebook and messenger are known to cause these issues, there are alternatives but it may be worth a try.
I have no issues with my phones battery and last a day no problems.
I can use my phone all day at like 85% brightness and then not charge it overnight, wake up the next day and still have enough battery. Usage differences aside, the things you should be looking at are the kinds of apps you're using and the way you have your kernel configured. As suggested previously, apps like Facebook and Facebook Messenger are widely known battery killers (Metal is a good alternative). Make sure you have adaptive brightness on, the screen is, by far, the biggest battery drain. Lastly, but more importantly, configuring your kernel and cpu governor would really help. I know you said you're running the ElementalX kernel, which is a fantastic kernel. I'd recommend getting the ElementalX Kernel Manager app from the play store and using that to tweak the kernel to your liking. Specifically disabling Touchboost and trying some of the tweaks in this thread. Touchboost is a battery killer as well and rarely effects the fluidity of the phone. The tweaks / profiles in the post I linked are an easy way to apply different values to the tuneable parts of a CPU governor. These values effect things like what frequency the CPU is at under a particular load, the input boost frequency (the frequency the CPU jumps to when you interact with the screen), and generally how the CPU behaves. In most cases, users have reported a nice bump in battery life AND performance. Some people are reported achieving over 6 hours of Screen On Time on a single charge. If that doesn't get you through the day, then idk what will.
The battery in the N5X isn't huge, but it isn't tiny by any means. It really depends how you use your phone; everyone's different. I highly recommend doing what I said above, it'll make a huge difference in your device, I promise.

Would highly recommend AT LEAST getting a different kernel and following the same recommendations I made above. A different ROM that's optimized with UberTC helps with overall responsiveness and battery life slightly as well.
Hi thanks for the advice much appreciated I don't run apps like Facebook and Twitter not a fan however I will try a custom kernel and see if that makes any difference
Thanks again

thanks,
i an using messenger and Facebook, but i blocked their active wakelocks.. it think it does the trick. this is the problem with those apps, right?
when i'm not using the phone the battery consumption is OK, my problem is with the time i'm using the phone, so i think tweaking with the kernel setting may be useful... i'm trying to use free apps only, but i may consider downloading the ElementalX app if it turns out useful.
Regarding the screen - is auto brightness is a battery saver?
thanks for the help

The EXKM app has a number of good CPU governor profiles Built in.
I think it's really worth the couple of bucks.
Also if you're indoors mostly you can probably keep the brightness at 10-20% instead of auto which really helps with battery life.
I bought the elemental app last night and installed the elemental kernel before my phone used to say 8 hrs of battery remaining after installing the kernel it now says 2 days remaining what a difference I've kept auto brightness on disabled touchboost and I'm using the butterfly profile
Thanks for all the advice people

bought it too
so,
when you say use butterfly,
you mean you enter to cpu->governor options,
you load the profile for both large and big cluster,
and makes it "apply on boot"
thank you all again
