New builds don't have this issue anymore. I reverted a few things that were causing this.
[Nexus 10 Original Android Development] Poloasis:
Will the new build be a 1.6x or 1.7?
[Nexus 10 Original Android Development] bruce7373:
It seems with the latest build (05/11) that Pie and Ribbons don't play nice together. Pie will supersede ribbons on the left and/or right, but maybe that's intentional (?). But, at any rate, the gravity is off -- bottom brings up pie on the right. I do have Prevent Rotation de-selected. Anyone else seeing this?
[Nexus 10 Original Android Development] shadowblade330:
Loving this ROM after I came back to it. Just feels good to be back on it again.

Feels smooth and stable and has the customizations I need.

But can I request for a disable of full keyboard in tablet mode. It is kinda annoying when I need to chat lol. Thanks

great work
[Nexus 10 Original Android Development] slick_rick:
There's an option for that in Language & input settings already.
[Nexus 10 Original Android Development] shadowblade330:
Also one more request if center clock can work in tablet UI. It was working in Eos manta ROM. No rush but just something that would nice.
[Nexus 10 Original Android Development] c19932:
seems like recent builds dont have init.d support? any idea why its removed?
[Nexus 10 Original Android Development] mistermidas:
Loving this ROM....but I noticed it seems to reboot by itself once it hits 100% charge. Doesn't do this on Sentinels CM ROM, or Mr.Robinson's AOKP PUB. Anyone else have this issue? It ONLY reboots on a full charge....no other time, odd.
[Nexus 10 Original Android Development] shadowblade330:
That is odd. Never had that problem. Did you do a full wipe and which kernel are you using?
[Nexus 10 Original Android Development] mistermidas:
Yes full wipe, I came from cm10.1 so I had to. I'm on the 1.07build now using Trinity kernel. I didn't have that issue until I switched to Carbon ROM....well, lemme rephrase. I had it before a while back, but found out that Seeder app was causing it, uninstalled the app and didn't have the issue again. This was over a month ago and just happened again for the first time again when I installed this ROM a couple days ago.
[Nexus 10 Original Android Development] shadowblade330:
Maybe the settings from seeder app came back try installing it again and clear data uninstall and see what happens
[Nexus 10 Original Android Development] mistermidas:
Settings came back from an app I haven't had installed in over a month.... AFTER a clean install on a totally different ROM? I seriously doubt it. Thanks for trying to help though.

[Nexus 4 General] dweekie:
I've always been a big fan of undervolting. These are the lowest voltages I can get stable at these common speeds. I found I can underclock the Matr1x kernel further than some others I have tried for some unknown reason. How low have you been able to go? Also, what programs do you use to test stability? So far, I have been running Antutu test completion as a measure of stability. Any suggestions otherwise?

288MHz - 650mv

1.02Ghz - 800mv

1.51Ghz - 1000mv

ROM: Bionic AOSP V3

Kernel: Matr1x 6.5
[Nexus 4 General] WarToilet:
Noob question~ Why do people undervolt?
[Nexus 4 General] Addsome:
To increase battery life,
[Nexus 4 General] Stennan:
The Long answer is that the CPU has a number of parameters where Clockspeed (MHz) and voltage (mV) are two. Clockspeed, well that is speed. Voltage is related to the amount of energy provided to the cpu, undervolting means that you feed the CPU less juice but demand that it runs at the same clocks. You are essentially starving the CPU,it uses less energy, but can become unstable if the voltage is insufficient to maintain operations. Manufactures always have extra voltage as a safety margin so power users can check their CPU bin (slow, normal, fast or faster) and lower voltages step by step until they crash the phone during a stress test, increase the voltage slightly and boom, your phone uses less battery power while being just as fast.
[Nexus 4 General] estallings15:
I undervolt to reduce heat. It makes a significant difference. The battery saving is minimal, but the temperature difference is VERY noticeable.
[Nexus 4 General] undercover:
Took words from my mouth. This this and this. It reduces heat, which in turn reduces battery use. UV by itself doesn't save a lot of battery, it's the consequences of it. I'm normally not a fan of UV, but with current N4 sw/fw it NEEDS it. It's way too high.

Interesting observation. As of recently my phone jumps up by 3-5c from 37-38 hover. Never used to do it before, not until i got it up to 50c for about half an hour last week. Previously it would stay steadily at 37-38, now it spikes up now and again during use. What's interesting about is that once it goes over 40c battery use increases drastically. So i wonder if people that have really good battery life don't have phones that go over that temp often and vice versa.
[Nexus 4 General] ckarv:
I haven't played around with the values too much yet, just a -100mV across the board. This seems to work just fine, so I might experiment some more..

Using Franco test-r69 at the moment.
[Nexus 4 General] dweekie:
I undervolt to prevent heating like others say. My Antutu scores drop like a rock when I'm at stock clockspeeds mostly likely due to thermal throttling. Now I can run it repeatedly without having scores drop. It saves battery and runs faster while running games even for very short periods of time, so I am a big fan of undervolting. :good:
[Nexus 4 General] hicks12:
Undervolt to reduce power usage, think of the stock voltage as normally being more than is required, think of running for a bus yet you have 2 minutes why waste energy when you can walk and still make it :).

Undervolt for less power usage and less heat produced meaning battery performance is better (cooler battery is a more efficient one) and performance is up as you avoid any thermal limits in place :).

Great stuff undervolting, I have managed to get -150mV across the board ( 1.5ghz @ 1000mV) and 288mhz is 162.5mV :).
[Nexus 4 General] italia0101:
I came from a nexus s ... And one member of xda went to amazing lengths to show that undervolting really made very little differences in battery life ... And it def wasn't worth the instability .

He did loads of tests and I mean loads and basically showed that in helped so little that if you had a reboot you would use more power in rebooting then saving via undervolt

However . it is worth it for the heat decrease for sure
[Nexus 4 General] Addsome:
The more the heat, the faster the battery drains. Since undervolting decreases heat, im sure it should increase battery life. Maybe not for browsing or calling, but playing a heavy 3D game.
[Nexus 4 General] zakoo2:
is it normal that the higher the frequency the lower the voltage in setcpu?

screenshot: http://db.tt/k6r8c5oI

I'm quite new to nexus 4 undervolting, what's the average amount i can lower the voltages with? (i have a nominal CPU)

sent from my Nexus 4...
[Nexus 4 General] aimcr7:
You can do it from franco kernel updater, from frequencies and voltages - voltages - cpu voltages

But i dont recommend you to undervolt if you dont know what you do. :)
[Nexus 4 General] zakoo2:
I'm familiar with undervolting both on PC and on phone, but i had a Motorola defy before my nexus and undervolting there was a bit different. :)

[Nexus 4 General] FatalityBoyZahy:
How are you able to undervolt with SetCPU? I'm not seeing that option using CM10, and Harsh's kernel.
[Nexus 4 General] noobiekins:
Former nexus s user here, the reason nexus s didn't benefit in battery life much was that it only had 1 core, and used a higher nm manufacturing process, 65nm -> 28nm. Lower voltages in the 28nm means that it multiplies the heat/power savings more than a 65nm, and the 4 cores multiply the savings by up to 4.
[Nexus 4 General] zakoo2:
don't know, it was just there. did you try to reboot after installing the app?

[Nexus 4 General] younix258:
Yes. Do however much you can. Here is my procedure:

I set max and min cpu freq to 384MHz, set gov to performance. I lower 384mhz voltage. Then i go into cpu stability test and test a few minutes to ensure stability. When i find crashing point, i increase 50mV over the highest point at which it crashes and i call it a day. I do 50mV because as battery dies, voltages vary slightly. I wanna make sure it is very stable so i never have to worry.

Anyways, after that, i do the same for all the other freq steps.

Here are my results:
[Nexus 4 General] mefistos:
will try! thank you! :)
[Nexus 4 General] opticaldh:
I am using Franco.kernel r71, franco.kernel updater to undervolt my nexus 4.

After I set the frequencies and its voltage, should I check anything else like the "Set voltages on boot" or "Set setting CPU setting on boot" or "Set governor control on boot"? I haven't check any of them. Then I reboot my phone, I go and check again, everything return to before I set the voltage :(
[Nexus 4 General] Addsome:
Don't do set CPU settings on boot because that would mean if you make a mistake in the voltages, your phone will keep on putting those same voltages and you wont be able to turn on. Just put them in again when you restart.
[Nexus 4 General] rr5678:
Self explanatory. 1512's default was 1200mV.
[Nexus 4 General] younix258:
Wait wtf? You do realize that Voltage and Frequency should have a proportional relationship right lol? Thats def the weirdest uv ive ever seen. Also, 800mV at 1.5ghz is crazy low. Are you sure your cpu can handle it? Are you sure its clocking up to it? Whats your governor set on? Whats your max frequency?

EDIT: oops, scratch the part about it being weird, i didnt notice it was just stock V except 1500mhz.
[Nexus 4 General] Roxxas049:
What he didn't show is that he has his min and max at the 1.5ghz. Is it stable? and hows the heat on 1.5 all the time?
[Nexus 4 General] Nuu~:
No, 800mV is not stable on 1.5GHz. either it's not set correctly or it displays it wrong.
[Nexus 4 General] dweekie:
wow, thats low.

[Nexus 4 General] Ipse_Tase:
2000 pts Antutu drop when UV?

Question for the collective brain: I did a fairly conservative UV (-100mV) and my Antutu scores dropped by 2000 !!!!

I'm on Franco r72 and PA3 (see sig). I have a "Fast" binning.

Any idea why? I cannot imagine a technical explanation.... :eek:
[Nexus 4 General] 00Droid00:
I think there is a problem with trixster. Undervolting doesn't seem to stick.
[Nexus 4 General] younix258:
Did you change governor or any other setting? The uv itself shouldnt lower perf at all, if anything, it will increase perf as processor is less likely to throttle die to high temperatures. Check your premises
[Nexus 4 General] Ipse_Tase:
That's the puzzling part: I didn't change anything BUT the voltages. I can reproduce at will, it wasn't a fluke. GSam Batt Monitor does not show any diff in temperature (as you said, I should actually drop by UV).

:confused:
[Nexus 4 General] younix258:
Does putting voltages back put your antutu scores back to normal??

If it does, im gonna assume its a software glitch and if you really wanna uv, i would suggest trying a diff kernel or rom. Though you might manage to fix it by clearing cache, fixing permissions, reflashing etc. You never know.
[Nexus 4 General] Ipse_Tase:
Yup...like I said, this is reproducible: every time I lower voltages, I get lower scores...I reboot (since I don't make the changes persistent) and get 2000 extra points. I reflashe ROM/kernel but nothing changed. Wiped cache and dalvik in the process.

What worries me is that I'm the only one complaining :)

I doubt this could be hardware, but I assume otherwise someone else might have noticed here.
[Nexus 4 General] trillo69:
Compare detailed results from antutu, that drop in the score should be exclusive from cpu tests. You can even run selective benchmark, as you are interested only in cpu results.

Battery life is longer but that may also be due to the Franco r111.
[Nexus 4 General] Vanex:
Hi, I know absolutely nothing about underclocking and undervolting, and very little about Android in general, to be honest. However, this thread has got me interested in getting into it. Improving battery life, battery temperature and battery life expectancy are the main reasons. I've downloaded SetCPU. Does anyone have any recommended settings that they've found worked for them? I've currently set it so that Max CPU is 1026 MHz and Min CPU is 384 MHz, and "on demand". I arbitrarily chose these values though.

Cheers!

P.S. I am running Paranoid Android 3.1 March 21, stock PA kernel, if that helps.
[Nexus 4 General] younix258:
Lowering voltages and freq will do little to improve your battery life as far as i know. People undervolt mostly to reduce heat (or they should) since the cpu already only eats a small chunk of your battery when compared to your 720p LCD and your modem etc. and you are only lowering the voltage a small percent.

Lowering frequency is likely even more useless as the lower the frequency, the longer the cpu must be at its maximum in order to complete any task. Theres this concept of "the quicker your finish, the longer you can idle".

You should lower frequency if your phone is unstable at the current frequency-voltage combination. You should UV only if the temperature of your CPU is high and your phone can handle the UV.

Another thing is that the battery heats up more because of the amount of load on it and less because of conduction of the heat of the other components, so worry more about lowering consumption first and then about lowering heat in other components. Try to use wifi instead of 4g and lower brightness or use auto brightness since those are the biggies (imho).

[Nexus 4 General] blitzzz3434:
To be honest, I wouldn't worry too much unless you are a hardcore gamer (playing for 3+ hours). Just make sure you don't have battery charging when you are playing games as it will create even more heat and eventually ruin your battery.

I've played temple run for an hour or so and haven't had a problem. So you should be fine.

Over clocking and / or undervolting is part science, part art. The numbers you see bandied about here can not be treated as gospel. It worked for one person, maybe. Also, keep in mind that some people will fraudulently publish faked numbers to stoke their stunted ego.

Another thing, there are too many inexperienced users who are misled into thinking that they can OC/UV like the more experienced folks.

How many people run Franko kernel and think they are the sh$ts when there are better kernels? Look at the number of posts here who are either complaining or having problems when they are running franko kernel. Don't they know that franko kernel does nonstandard things to their phone?

I am not picking on franko kernel. All other kernels also have flaws and deficiencies. Nothings perfect. Understand that and you will be on your way to eternal bliss.
[Nexus 4 General] Illudrium:
I guess now would not be a good time to expose myself as an inexperienced user running Franco kernel and looking for guidance. Mainly interested in undervolting to decrease temps. Ive read stories of people screwing up their phones doing this so i want to make sure I'm doing everything right.
[Nexus 4 General] jose13683:
At the moment I'm -50mv for each frequency...trying to find the optimal values step by step,testing each step to see if it is still stable. I think that battery life will not be really affected, but the phone is really hot after some game sessions, and in this cases UV should help!
[Nexus 4 General] MisterWinkey:
There is another thread on this also........

My nominal bin CPU can only go -100 stable. The scale starts at -900. It reboots at -750 and has issues when the battery gets low at -775. Best value at 385 MHz is 800.

Wife's fast bin phone can only do a -75 under volt but her CPU starts at -850 and end up at -775. Any value lower on 385 MHz and it restarts.

I had better results from the copper plate hard mod and under volt. Can't recall the thread title....something about thermal throttling hard mod?

Also some of us like Franco kernel. Battery life was better than others I tried.

Good Luck!
