Remarks
1. Try it at your own risk.
2. System instability reported with 2 active cores. (Original LG QuadGearBox)
3. The 3 cores active option does not work. I don't know why. I leave that option to test by yourself.
4. This app has been tested on rooted phone. It should work on non-root phone, need some test please.
Bugs
Sometimes it just doesn't work. Reboot phone will fix it.
Note
V1.1
initial release
V1.2
Activate by Power Saver
V1.2.1
Fix incorrect popup message.
Usage
Open LG GearBox
Choose CPU Max Speed and Active Cores then click Apply button

Testing it with my unrooted phone.
Setting clock to 1100, use 2 cores.
Quadrant benchmark then drops to 28xx (before is 47xx)
So I guess this app worked.
Let's see next if this setting have effect in battery usage.

Thanks for testing.
I will edit the post for no root requirement.

app works as it should, but i don't think that it will have a big effect in Battery usage, the Management for the cores is quite good and
quad is used not much, also the core's itself are not the big drainer's.
If we have full access and custom Rom's/Kernel's - than we can expect power savings ....

Underclock does improve my battery life and also less heat.
V1.2 will be more useful by Power saver trigger.

yeah, i misspelled that, underclock surely will improve, but i think reducing the cores will also give us more juice, but not so much i think,
but i test the new version now

Actually LG Hidden Quadgearbox is where I started to look in LG API. Basically, use the same API to set 2 cores active.
I think freeze/restart is the reason why LG hasn't release it in official firmware and that's why we need this app

Im saving more battery on this than quadgearbox. No problems with it so far - Singapore V10C - except the speed resets to 1.5GHz after reboot. Number of cores didnt.
Edit: is the fix for the resets coming any time soon? My setting is 2 cores at 1.2GHz. After reboot its 2 cores at 1.5GHz

Works but it freezes my phone twice already.
Also, it fires up the other cores even though I set core number to 1.
Will be keeping it but I won't be using it till next stable update...

Can this turn all 4 cores back on as I believe lg quad gearbox has turned 2 off and they won't come back on

The originally QuadgearBox set active cores on boot so you have to turn eco mode off in QuadgearBox.

Exactly.
Once, I had 3h screen time, browsing and facebook, and still 65% left. So, theoretically, using Wifi I could browse for at least 8 hours.

3Hrs sot,23Hrs total time & still 49% charge remaining :highfive:

Stop using SOT as some sort of benchmark. SOT differs for everyone and it depends what you're doing. For some, 3 hours is great, for some that's bad. It depends what you're doing. Anandtech got 6 hours SOT on the wifi benchmark for the Nexus 4 which requires the screen to be on at 200 nits brightness the whole time. You can easily get 6 hours reading an eBook.
So what?
Furthermore, underclocking your phone down to 1ghz isn't really an acceptable compromise to most.

Running it on dual core mode plus underclocked to 900 mhz and undervolted... Of course u can hit 6 hours
Nothing too fantastic

Also, please stop making this "contest" on who's getting better batter life... just charge it every night before you go to bed, and everything will be fine.
Going camping in about 2 weeks, no internet there, i'll wipe everything, and go on a clean, stock, 4.3 ROM without installing any app, that way i can determine how well android works with the battery on its own.

CPU Info

I am using Carbon ROM 4.3 with Chronic kernal. The settings were at a min of ~1700mhz and a max of ~2200mhz. Before i set this I let the cpu temp cool to about 23 degrees Celsius. I then set the cpu governor to performance. Then I started running AnTuTu benchmark ver4. After the cpu integer test the cpu froze up. I was cooling my phone using a freezer with the phone on a paper towel which was on a bag of ice. The CPU crashed at the CPU float point test.
After another test I found that my CPU becomes unstable after 2160mhz.
The settings for the posted benchmark were CPU Min at 1674mhz and CPU Max at 2160mhz with the governor set at performance.

The minimum freq is mute when the gov is performance. Performance just keeps the cpu at the MAX freq.

I am aware of this. I did have it in the freezer until it cooled down enough. The problem was not overheating, it was the CPU becoming unstable at full load with the processor being overclocked. The phone was still cold but it went to a reboot or just turned off.

Gotcha. I missed that part. I wasn't fully awake yet at 4:30am.

Ok buddy here is your issue buddy its all about volts and throttle limits ive been fine tuning oc steps on antutu, cf bench, geekbench2 and geekbench3. Im stable all the way up to 2106 so far I use ktoonzs kernel cuz it has more options in his app the control alot of the throttling and volts. Ok understanding what it means what the phone just shuts off or reboots when the phone shuts off and wont cut back on you either have to do pull the battery out or plug the charger in to get the phone to boot up that means you had a power overload it drawed to much power on the battery which means you neesd to drop volts on your max step. Now if the phone is just rebooting or if the app FC back to the home screen that means that you dont have enough volts for your max step you only have to add or substract volts on that one step not on the whole board the best way to do this is just by finding your volts for that max step first yes scores will be low but once you find the volts then you start adjusting the throttle limits that way you can control the heat of the cpu but once you find the sweet spot of that oc step move to the next one and start over again for the next oc step doing the steps I listed above I will post pics of what I gotten so far. On a further note I have found that the freezer trick hurts you more then gaining anything cuz if you cool the cpu and battery to much it will make the cpu run sluggish cuz its to cold to run and if the battery is to cold it makes the phone think it dont have enough power to run on that oc step and makes the phone reboot so bare in mine the freezer isnt always the best way to do this I found that if the battery is below 28c it will reboot the phone during benching and if the cpu is below 25c it sluggish as hell the best app to use is cool tool on the app store if you use kt kernel I can give you the direct path to monitor cpu temp like his app does hope this helps you understand alil better of whats going on if you need anymore info just pm me

Nexus 5 Undervolting thread

I found this thread very useful on the N4 forums, so here it is for the Nexus 5.
First, what is undervolting?
No two CPUs are made equally, every one is slightly different. This means they each need a different minimum voltage to run completely stable, so manufacturers set it high enough so that every chip can run without needing a voltage tailored to that specific chip. But this means that most devices can have their voltages lowered, and still run 100% stable
What are the benefits of undervolting?
In my experience, heat reduction is the main benefit. However, this heat reduction has implications elsewhere; for instance it means the thermal throttling will kick in later, so there is less of a performance drop. Also, less power is wasted to heat, meaning marginal gains in battery life. If you cannot run higher frequencies, i.e. over 2.26GHz, undervolting/overvolting these frequencies may help.
Any disadvantages?
Not really - you may experience reboots and instability, but that means you need to raise the voltages. Also, make sure you don't check set on boot until you know the voltages are stable, but if you have any problems you can flash the stock kernel, or in worst case wipe the data from a recovery.
How do I undervolt?
Many CPU apps are available to change the voltages, but personally I use Trickster Mod (donate). Just slowly decrease your voltages, small amounts at a time, and set them on boot when you are happy they are stable.
If you want to really want to get your voltages perfect, you can set the min/max frequency to one you want to modify, and edit each frequency to perfection. To save time, I'd recommend starting with the highly used frequencies - many apps can tell you which your device uses most often.
CPU Binning
I know on the nexus 4 the cpu bin was related to the amount users could undervolt, and Im sure the case is still the same, so heres how you can find out your CPU bin: http://forum.xda-developers.com/showthread.php?t=2515593 It would be useful to include your CPU bin in your post.
Here are my initial voltages, running ElementalX v0.7, CPU bin 3 and PSX - please, feel free to share yours (and your knowledge);

Same has just happened to me too, so I'll bump them up to -62.5, although I think I should be able to keep the lower CPU clocks at lower voltages as I'm sure the higher ones are used when turning on the screen

I'm running franco r14 and got two almost immediate reboots on your settings. Gonna go a little easier. I have no experience doing this, so it's still a bit confusing.

can probably go a bit easier on the higher clocks, my settings are -75 mv below 1.8 ghz and -50 above. Just played some deer hunter 2014 and seems to be fine. No reboots so farr! My bin is 3 as well. Running stock rom with faux003b6 kernel

I have a bin of 3 as well. I've only been brave enough to go -37.5 on Fauxs latest beta kernel
Sent from the jaws of my Hammerhead!

Got a CPU bin of 2. I went for -50 undervolt for all frequencies on Faux kernel 002 a few days ago, no reboots so far. Haven't tried -62.5 but -75 was too much, so I'll stick with -50.

I was a little bummed when I found out I had bin 2, but I've been running -75mv no problem for the past few days on bricked kernel

You guys are lucky. My phone has bin of 1, could only uv 50mv on high frequency and 75mv on the low end, and I have higher default voltage to begin with.

It might be helpful if everyone included the actual voltages as well, as some have reported starting with different voltages, and some kernels UV put of the box.

Battery life and CPU

Although this might seem as a question. It really isnt.
What kind of battery life do you get on the First? Screenshots would be nice, but what is like the max time and min time you got and what kind of setting do you use, voltage, clock speed, usage etc.
Also has anyone been using the MSM-DCVS (dynamic clock and voltage scaling) CPU Governer? And if yes then have you gotten better battery life? I will do a test tomorrow and see how it goes.
My best stats.
Well before i got into cpu governors, by default the phone uses on-demand and i could max out 14 hours with variable usage. screen on maybe 50% of the time the phone was on and minimal gaming. texting. I dont have data so that didnt take any battery (i hear 4g and 3g take away lots of juice, is that true?).

Okay. So just did a quick test with msm-dcvs.
Basically for 5 minutes I tested each governed doing the same stuff.
Msm-dcvs utilizes deep sleep ALOT more. Almost 8 times more than on demand. And doesn't really use anything in between. So it goes from deep sleep to minimum 300mhz to get it going and then jumps to the max of 1.4ghz and if the screen is on it uses 700mhz.
So using deep sleep it saves batter.
On demand on the other hand tends to use 300mhz instead of deep sleep. It also jumps around a lot between all the various clock speeds using just about anything it can. So i guess on demand will get worse battery life but I will report my findings in a few hours seeing bow battery life goes with dcvs.

Just a quick update. On demand is crap. Performance is really good and dcvs is performance just more intelligent

Use performance. It has a really fast "rave-to-idle" speed. This means that the phone will finish tasks faster and go to idle/deep sleep. So it should save you batter. Unless you don't mind lag and use msm-dcvs which is performance just it takes time to ramp up the speed.

What app do you use for this? All the ones I've tried don't make any custom settings stick

CPU master by antutu. I've always used it. Best one there is

Alright I'll try the app. BTW I'm pretty sure 918mhz isn't the stock minimum... Must explain my horrible battery. What do you have yours on?
Edit: so far so good. I'm feeling some better battery life even tho it might just be a placebo effect I know that the CPU will have less strain & rest more now that the minimum is at 384. And few more questions, what do you have set for your I/O scheduler and also did you configure the voltage?

It's important for battery life, that the phone goes into deep sleep while screen is off. Use this app to test whether thats the case: BetterBatteryStats
Also you can see which process "wakes up" the phone while it should sleep.
My First normaly runs about 2 days without charging. So battery is pretty good!
PS: I'm using deodexed rom with stock kernel.

Wow that's great battery life.
I'm yet to test dcvs in my first and see how long that lasts me. I have Wi-Fi on all day. So I can get up to 14 hours max.

No I have yet to figure out io bit tinkering with voltage isn't a good idea since the battery is specifically set to a voltage the phone needs.

Okay I have some new findings. Idk about the custom kernel...bit with stock you only get 3 I/o schedulers. Noop, deadline, and cfq. Noop is first come first serve. Deadline reorders the task sequence and does what it thinks should come first...good for like gaming. And cfq. Which evenly distributes the power amongst all tasks. If you are using cfq make sure you kill unused tasks all the time. If you use a lot of things on your phone and multitask a lot use deadline. Noop is pointless unless you don't use your phone for anything. And cfq is just an alternative to deadline. So I/o won help much.
Then in CPU master. Go to advanced. And press "disable perflock". It will explain what it does. Hit set on boot. And reset you clock settings. Now we shall see what we get.

Okay guys. I used deadline to see if that would change anything. With the same dcvs setting with deadline I got 15% batter down in 2 hours. That's pretty good. That's 7.5% an hour.
And this is with screen on and wifi on about 70% of the time.

Okay this is my final say on how to get the most out of your battery life.
There are two set ups
1. Lag free/ smooth set up
Min 384mhz, Max 1080mhz
Governer: Performance
i/o Scheduler: Deadline
-This set up will save battery why? Because 1. You don not need your max 1.4 ghz to keep the phone running lag free, and in performance mode, the phone is LOCKED into 1.4ghz until you dim the screen and it goes into deep sleep. no inbetween. So clocking down will help save EVEN MORE battery. So unlike dcvs you will not have lag when you turn your screen on. It will jump from zero to 1ghz in a few milliseconds.
2. Inteligent
Min: 432mhz, Max 1.4ghz (default max. Dont over clock)
Governer: MSM-DCVS
i/o Scheduler: CFQ
-This set up will save battery, i go down about 1% every 6-20 minutes depending on usage. (6 being max usage and 20 meaning iddle). Once you turn the screen on your device will lag slightly and then will work just fine. This set up is good for those people who dont ALWAYS need max performance. Example: Reading an email doesnt require your phone to be locked at max frequency all the time so it will down clock the device. It simply takes time for it to rev the engine.
3. On Demand
Well this is simply absoule minimum to absolute maximum with NOOP as the i/o. This is the ultimate ondemand set up as it will do what you are currently doing first then do the rest while constantly changing clock speed.
Also...btw changing clock speed takes battery that is why performance saves batter not uses it. Its either deep sleep or max and thats it.
I will add screenshots to this soon once im done with all my tests.

Battery life today on msm-dcvs
I should be at 30% right now bit pretty good battery tight now

Tried today MSM-DCVS scheduler on my stock rooted firmware. Don't like it. Lags a lot when screen on (and CPU at max 1.4Ghz). And i do not see any significant battery improvements, instead it seems that it takes longer time for phone to do background tasks like mail checking etc.
Concerning battery life - in general I receive 3-3.5 hours of screen time. And it can be 1 day to 3. It all depends on usage, but screen on time never goes above 4 hours.
In attached file - Stats for my phone while traveling from the U.S. to Russia. As you can see, delivery does not take very much time And in standby mode phone can last almost two weeks (with wi-fi and nfc on).

Personaly i dont have NFC or 4g on at any time. 1. i dont have data and 2. i dont use nfc cause the so called "modern world" is still stuc on stupid apple devices.
I noticed the following issues with managing the cpu
1. When setting cpu clock speed, after about 5 seconds after you left the app it changes the clock speed back to how it was
FIX: in cpu master (or the app of your choice) go to advanced and turn perflock off. then go to the cpu settings and set the speed you want. you must do that every time though cause of the htc kernel
2. MSM-DCVS lags.
FIX: set your minimum to 450-500 mhz
3. 4g drains batter (or so i hear)
FIX: idk yet but if someone could show me their battery life with 4g on and normal daily usage i could try to figure something out.
Hulo. Try this set up
Performance, 300mhz - 1080mhz, deadline
IDK my phone syncs things quite well and lag isnt a big issue for me, i can deal with it because my old phone overclocked is 700mhz so lag isnt anything new to me. So i just notch up the minimum to reduce it.
MSM-DCVS saves batter when screen is off and when screen is on but idle. playing games or actively using the screen will drain battery no matter what setting you use. This is made for people who are constantly on their phones.
Performance saves battery when screen is OFF period. When screen is on its at its max. this is best used for people who dont use their phones alot.
With dcvs i got an extra 7 hours of battery life. usually i get 11. But i hear with 4g on your battery dies in about 6 hours? is that true?!

I'd just like to add that 4g actually consumes LESS battery than 2g/3g/3.5g only LTE tho. That's because it's more optimized and advanced I've read and experienced it in many occasions

Alright then. Interesting. My friend on his s3 gets 6 hours of battery with 4g.

I should add that the optimized battery life for LTE is only true tho for new snapdragon CPU's including Apple's processors as well. I'm not aware of tegra or any exynos at the moment.
