Hello,
I've picked up my first Android device to mess with and caught a deal on the Hisense Sero 7 PRO (Google Nexus 7 <1st Gen> clone).
I was wondering if anyone was aware of a kernel that supports undervolting? A few of them allow overclocking the CPU, but I'm more interested in Undervolting for extending battery life.
I've read through as many Sero 7 PRO centrix posts as I can, but I cannot find mention of undervolting. Any help would be appreciated. Thanks. :good:

im just speculating, so dont quote me
many times oc and uv go hand and hand, so frequently it is included.
im thinking it is a good possibility that most of them have the ability to do both and it just is not stated.
i would make a backup first, then move it to a safe place, then try some out.

I had hoped they went hand and hand but every app I've DLed that lets me play with parameters and advertises the ability to OC and UV, has had the UV section grayed out or it doesn't show up like in the screenshots for the app in the play store show. This is why I was wondering if I perhaps hadn't hit on the correct kernel yet.

I know I will probably get accused of being, umm, "frugal" but I don't want to pay for the app only to lose it when I upgrade to a new ROM later. Suggestions would be appreciated.

CPU Planner worked fine for me when was running stock ROM.
SetCPU is free for XDA members. Its on the forum somewhere. Though if you like it and it works then you should buy it/donate. Also I think someone made a free alternative to SetCPU and posted it up somewhere on the forums as well. Can't remember what he called it.

It is in the HTC Dream forum...but do contribute if the software works. It helps keep apps and developments comin'!

Its only 2 bucks and well worth it imo
Upgrade to CM7 and you get all the functionality of SetCPU already baked into your ROM

Changing roms wont make you lose paid apps.

Quick question: are there benefits to runing SetCPU on a stock rooted NC? I hear the most you can clock a stock rooted NC is 800MHz (the Nook's advertized clock speed), but I'm unclear as to whether the Nook Color really runs at 600MHz most of the time.

The only benefits I can think of, using SetCPU on a stock rooted NookColor would be maybe preserving potential batter life and increase your CPU processing "on demand" (one of the scaling options with SetCPU); there might be more benefits, but the only thing I would think is preserving battery life and manging cpu processing when not needed.
And to monitor if your device really runs at 600Mhz, you would another app to monitor the cpu processing, a good app that might help you view what's going on behind the scenes is Norton (Beta) Utilities and System Panel, both are available within the market.

Why would you lose it? Apps are attached to your Google account, not your ROM or device.
There's one rolled out with the 6.8.5 image called "No Frill CPU". It works fine and I am currently OC'ed to 1.1Ghz.
"CPU Tuner"

I have a rooted stock NC and SetCPU is set to run at 300MHZ unless an app needs the 800MHz clock speed. I now get days of run time before charges. Originally I got less than a full day. Well worth the price.

How exactly did you do that? I just got this and I want to make sure I'm doing it right. All I want is to conserve battery life because I don't want to charge it every day.
On the Main tab I set it for "ondemand" with a Max of 800 and a Min of 300. I chose two profiles Screen Off and Battery (which I set to <20%) and set max and min at 300 for all. I didn't change anything on the Advanced tab so the Sampling Rate is 300000, the Up Threshold 95, Ignore Nice Load and Powersave Bias are both 0.
For the people that maintained root through the update; are you able to use an app like setcpu or something to underclock the newly overclocked kernel?
Why would you want to underclock it?

to improve battery live, but really undervolting would be more useful.
for underclocking, the companion core works much better and is very effecient for standby/basic use senarios.
undervolt won't work until we can flash custom kernels, which need a custom recovery to flash them, which needs an unlocked bootloader.
i don't think apps like setcpu know how to deal with tegra3's 4+1 core setup right now, someone can correct me if i'm wrong
My guess is that the UV/UC battery gains are going to be quite small with the ninja core taking the majority of the strain. There should be some kernel source from nvidia which indicates what the transition is from the different states - maybe the best gain would come from locking out the G processors.
I saw some LP <->G switching info in dmesg with a pre-ICS version, but it seems not to be there any more...
Well the reason I asked was because I'm one of the people who gets nothing but boot loops after the ics update. After trying everything, I was wondering if this could be done, which would narrow the issue down to a kernel problem.

Is there a version of this kernel without the OC? What I'm really interrested in is the BLN support. Most of the other roms that have it have so much other junk in them, they don't interest me. This one seems very slim and to the point, but I have no need to overclock and further drain my battery.
Or in this version, can I simply "not" overclock and it's just an option?

Overclocking is just an option.
Yes, you can set the cpu to do whatever you want. Max and min and decide on what governor you want. Setcpu is what most use I think. I use system tuner pro.
Excellent. Thanks to you both. I'll give it a go.
If you look in development on the end posts of the collective rom thread there is a post with the bln fix you can flash over your stock root to take care of that. I would post it here but my note won't let me upload files here.

Hello, could anyone please tell me what some good settings on set cpu , for a rooted T-Mobile Alcatel one touch fierce would be ,

I don't have the same phone as you but Intellidemand / Zen (governor / schedular) seem to be a winning combination for performance vs battery life but it will probably vary from ROM to ROM and supposes the kernel you've installed supports it.
Perhaps you could say what you're hoping to achieve? Max battery life (slow the CPU down) vs performance.

Oh, sorry, I'm hoping to max battery life and maybe speed up the phones performance, (if possible) I got the paid app from the market even though we don't have the same phone but if you could share your settings I guess its better than the factory settings
Once again thank you, and sorry I forgot to put what I was hoping to achieve in my original post

You have to choose. Best performance or best battery. If you want the best compromise then like I said, Intellidemand and zen if your kernel supports them.
I'm not sharing settings as we have different phones and different Kernels so it'd be pointless.
I used to have lots of profiles for various times of day, screen on, screen off etc but now I pretty have two. One for general (min and max are whatever the kernel allows) and a profile for low battery where it max's the CPU at 30-50% whatever is max and changes to the conservative governor.

Ok see didn't know that, so I would choose performance over battery life then I am new to this and don't want to brick my phone I bricked a rooted android trying to change a boot animation using root explorer so just trying to be careful, also if you could help me with the "MHz" settings it would be great to the choices are 497, 754 ,988 & 1209 that would be great to
I have all the good root apps titanium backup pro root explorer pro and a lot others, but lol I just don't know how to use them yet...any knowledge on a boot animation logo change would be appreciated to I learned a little after I bricked ny phone I know that I didn't put it in the right folder but every post I read people say it bricked their phone so maybe I should staw away from it until I am a little bit more experienced idk.
But for cpu performance would be what I would choose
Thanks again..
Hey heroes of XDA!
I have a question, since watching a video from youtube, making a DIY gaming phone, he used a Mi 9, since the Mi 9 and Mi 9T Pro/K20 Pro has the same CPU and GPU, i wondered if i can overclock it too the same way he did, but since he rooted the phone to overclock it, i have doubts, if i root, overclock it to my heart´s desires, and unroot, does it keep the overclocked values? or does it reset?
here is the link for the youtube video where i saw the idea, and in minute 3:24 he shows how to overclock the CPU, GPU and the display (i know how to overclock)
im actually copying the idea he had, but instead of a Mi 9, im using a Mi 9T Pro/K20 Pro since i already have the device in perfect condition, i know how to root it, but i had to unroot due to safetynet issues that was way out of my knowledge how to fix the problem, thats why im asking if i can unroot it after overclocking the CPU so i dont have to deal with the same issues i had before,
i dont want a custom kernel/firmware or whatever, i want the phone as stock as possible excluding the chip overclock, heat and battery life isnt an issue since im planning to cover the back with a thin layer of copper plate, with a custom phone case (cutting the middle of the case) and im buying the blackshark funcooler 2 pro to take care of the heat, and since i already have a 20k mAH battery pack, power isnt a problem for a whole day outside my house gaming with the phone...
i know this might be a foolish question for some of you, but i dont know, since i never tried rooting then overclocking, then unrooting..
thanks in advance and have a wonderful day/night!
WRONG FORUMS!! AND I DONT KNOW TO DELETE IT!, I ALREADY POSTED A NEW THREAD IN THE PROPER FORUMS OF K20 PRO, SORRY FOR THE INCONVENIENCE!
