Show off your OC and UV settings here.

Every TF is different. Someone has reported being able to unvervolt by -250 or more. I don't know how the hell he did it. Anyway, I thought I'd start this thread to let people show off their OC and UV settings. I thought I could get a feel on what the stable limits are.
Remember, guys, it's only considered stable if the camera doesn't freeze. I don't care how much stress test you do. If your camera doesn't work, then it's not stable.

The 2 lowest clock settings there are, it's like 250 and 320 mhz or something I can run a 250 undervolt. This is extremely useful because I run on interactive and my tablet runs on almost no battery at all while on standby.
As for my underclocks up from that to about 1590s(My tablet can't handle 1600s) I have a steady 65 undervolt for all frequencies. I found battery life to be amazing...

Hi there! What are you using to undervolt and/or overclock? I'm using CPU Master Free to overclock, but it doesn't have any undervolting options.
EDIT: also, which kernel are you using that supports Undervolting and Overclock?

Prime kernel doesnt seem to support uV at the moment
Blades does
Clemsyn does
Dont think netformer does
Settings im still playing and waiting for uV on prime kernel as ive found it the most stable at the moment will post back later

Does your camera work when you set everything to -65? My camera will not work if I unvervolt 608 or 456 mhz.

mpdecision

I'm running fauxs kernel, and in his op it says for battery life to turn mpdecision off. When I leave it on only the first 2 cores run and idle at 384mhz, but when I turn it off all 4 cores are running constantly, and the 3 & 4 core idle at 702 mhz. Maybe I'm missing something, but how can turning mpdecision off be better on battery when you have all 4 cores running constantly instead of 2?

Sounds like you're running his enhanced stock kernel, the recommended settings only apply to faux kernel

No, I'm using the 008 mainline

mpdecision kicks in when you touch the screen it ramps the min cpu speed to 1026 so it uses more battery but increase responsivness

See, that I knew already, and it does make sense. But when I turned mpdecision off, it was doing the exact same thing, but instead of only having the first two cores online, it had all 4 cores online constantly with the last 2 at 702mhz. From what I read, people are saying turning mpdecision off is better for battery but I just don't understand how it could be with 4 cores running constantly instead of 2, unless I'm doing something wrong (which I probably am lol)

Best kernel for battery management

Hi guys. Do you know which is the best kernel for 4.2.2 for the battery management? Now I use jelly shot with marmite 8.5 bigmem
Sent from my Nexus S using xda app-developers app

You are probably using the best kernel for battery management... If you want to save some more battery, then follow some or all of these steps...
Change governor to smartassV2 and I/O to row
Go to developer tools and make max background running processes to 3 or 4
You can also overclock your system to 800Mhz max for saving battery
Use Greenify app from Play Store and hibernate all your apps, so they don't run in background
Jellyshot v4 was a real battery saver for me... Had been given around 5hr+ screen time in a single charge...
However, I switched to Carbon because it had more features, but obviously, a bit less battery life...
Try these steps for sure and I'm definite that you'll save huge hours of battery fr sure

I'll try. Thanks a million for your help!!!

I Say go for gamerzrom with stock kernel it has pretty good battery life and a lot better performance .. Carbon is also good but I have too many random reboots with it becoz its Still in nightly mode not a stable version and even for a nightly its pretty good .. And jellyshot is the king of all the roms with marmite 8.5 bigmem is amazing these are my suggestions best of luck !

Mulit-core hacks

So I have a very thought out question now I have a 4 core phone right? Well my battery life is below average and I was wondering if I had all my cores running at once would it balance out battery life? I just need some help from someone who knows about all this and are all cores mandatory?
Sent From My Liberated E970

You can select how many active cores are activated with trickster mod and (necessary!) a kernel that supports this.

I know how to and can with my kernel but I need to know if more cores are activated if the battery life will be better or worse
Sent from my Optimus G using XDA Premium HD app

I would definitely take a look in to what my batter usage is and how to control that before I worry about the cores. Just my two cents.
P.S. I am sorry but I believe the Multi-core in the title is spelled wrong.

More cores active would mean more processing power, and more processing power requires more energy(atleast on the same cpu), so disabling most of your cores would result in better battery life, maybe by a little bit though.

Hahaha I didn't realize it said mulit

useful topic

It seems to me that by disabling cores wont make a difference to your battery life, only to your performance. It doesn't matter if 2 cores work for 5 seconds or 1 core works for 10 seconds, it is practically the same power consumption

Play around
I would say download CPU-Z from the Play Store and look how much Cores are active and which clock they're at.
Then flash a custom Kernel, which lets you control the clock, govenor and how much cores are active, undervolting may increase your battery life too.
Play with the settings (PLEASE DO NOT RAMP UP THE CLOCKS or set the voltage to the lowest point you can, it may break your phone, stay reasonable, it's not my fault if your phone bricks) and look what's best for you.
Pro Tip: Take a look at the different govenors and look what they do. Google them!

I hope I could help you a little

Im using trickster mod and I know about all of this I studied up and have undervolted by 200 MV stable but I'm using the hotplug settings to 1:2 so not all 4 cores are active and I get almost two days on one charge!so I guess that does mean less cores use less power

I can reduce cpu voltage on all frequencies by 40 mV but gpu lags at anything above 450 mhz(performance governor), also I'm on doomkernel and I can't properly underclock for some reason...

Mine is 1574 mhz max and 300 mhz min interactive row, stock kernel and @Nut 4.3 ROM..do i need to set on boot the default governor? Battery life is good and not overheating too much while playing NOVA 3..

If you do that all your seffings will go back to default like governors. There should be the option to set the same parameters on boot to keep all like you have right now. I don't know if on rooted Z1 there is this settings but should be because I remember I did all of this with android on different devices.

(I see a lot of people are using row though, so may need to test it and see if I notice a difference - that and undervolting..)
