You can actually tap on the +/- thing right abive the voltages table and set an offset.

Try going down in 50 mV steps. Go as far as it crashes (don't set stick on boot!). Now try to go +25 mV on top of the voltages that crashed and run it a few days. If it doesn't crash congrats. If it does try to set the offset higher until it does not.
[Nexus 4 General] JamesInsights:
Thanks for the help! The value in offset seems to be crazy high though.. Or is that in v and not mv.

EDIT: nvm got it sorted out, thanks again!

I have a faster binned CPU, I'm able to lower voltages by 150, but I can see some graphical artifacts and errors beginning to occur around there. No hard reboots or anything. I'd set it for -125 and everything been solid. CM 10.1 and Franco r117. 12 and a half hours battery, 3 and a half hours screen on, 1 and a half of that gaming. Best part is the temperature though, phone isn't feeling hot all the time.

Does undervolting have a long term effect on the health of the cpu? I've looked it up and some people have said that its not great as it 'starves' the CPU of the power it needs, and others have said it will help prolong the life of the CPU as it keeps it cool, reduces wear etc?
[Nexus 4 General] Spec-Chum:
You can't damage a digital chip by starving it of power, no. It has no moving parts, so nothing to be damaged, the transistors are chemical, not mechanical so nothing can grind together or break or what not. You can, however, damage you data as corruption often occurs if the voltage is too low :eek:

And yes, keeping a chip cooler will prolong it's lifespan but this is very greatly exaggerated, probably even an extra few weeks over it's entire life, so unless you do something really daft, we'll both have a new phone well before the chip gets heat damaged under normal use.

Don't worry and enjoy (and nandroid) :)

[Nexus 4 General] Beremus:
Undervolted -175mV. PA 3.1+ with franco.Kernel r121. My CPU is nominal and is very fast (4).

It's very stable but I need to test it a little bit more!

UPDATES#1:

After several tests and many hours, I have not really noticed a marked improvement in the battery life of the cell. In addition, the battery discharge by jump or 2% instead of 1%. The time between the jump is higher but still. My configuration was Max CPU: 1350 Min: 384 Off Screen max freq: 594. Now I'm trying Max CPU: 1188 Min CPU 384 and off screen max 594. I hope it will be better at least!

I tried a total charge with those configurations and I got 23h 45min ON with 3h47min On Screen Time. It's decent stuff.

I'll update when my phone dies.

motley undervolting

I'm on unofficial aokp pub and motley build 49 and I'm undervolted all the way down to 600mv at 304mhz and 1000mv at 1512, stability is very good, temperature and battery are all the best I have seen in my experimentation (I've tried franco, faux, and trinity besides motleys).

Also, just a question, why am I able to undervolt so much more with motley? I have a fast binned chip but usually I can only uv about -150mv across the board.

[Nexus 4 General] demon507:
Instead of writing -175mv or -150mv you can write voltage for min & max frequency

Bcoz I've a faster binned cpu and with -150mv i m still having low voltages than someother peoples sayin -175mv

Faster binned CPU

Franco kernel r134

Paranoid android 3.15

-150mv..(tried -175mv stable but once in a while it refuses to wake up) running -150mv uv from atleast a month

Edit: the idea behind mentioning voltages for min and max frequency is because voltages for different cpu's are configured differently..
[Nexus 4 General] N4ever:
Franco Kernel r134

Pretty stable, definitely a little noticeable lag when multitasking. All in all not too noticeable.
[Nexus 4 General] republitarian:
Okay thanks for the clarification. I started @ 384=900mv and 1512=1200mv

Now I have the exact settings as yours: 700-1000mv

I can't achieve lower then this, phone reboots.
[Nexus 4 General] Danny.ns:
Using francokernel r134, I tried to undervolt. I had a stock voltage of 1150mV for 1512mhz. I was able to lower it to 1050mV at the same speed (so -100mV on all speeds).

Upon choosing -125mV I had chrome crash on me. Going to try the mentioned voltages for a few days and see if I run into problems. I will also keep an eye on CPU temps (not worried) and how warm it feels in the hands during use (main "problem").
[Nexus 4 General] kelah:
I think google/LG messed up with voltages in more ways it looks on the first glance.

Put their values on the graph and You'll notice that the line is linear. But it should be somewhat parabolic.

It's easy to demonstrate on the graph.

Blue line - stock google voltages.

Red line - this I get when I set UV -150 (I can't go lower it).

Violet line - my stable setup.

As you can see my stable setup is parabolic. And in the center difference is big - 225mV at 1188mHz and 200mV at 1026mHz. For other values it ranges from 175 to 185. My chip is "FAST".

Green line consist of values crashes device immediatly - I set them and right after I tap on "apply" my lovely N4 rebooting. The point is what between them and stable values 50mV. If difference abot 5-25 device works but it reboot for sure in half of hour or something like that. This is the easy way to determine how much UV you can - just find values of instant crash and rise them about 50-60mV. These values are easy to find - no need to run long tests. Would be better to do nandroid before - many repeatedly sporadic reboots can corrupt some of your data.

My сurrent setup:

384 - 700 (-150)

486 - 700 (-175)

594 - 720 (-180)

702 - 740 (-185)

1026 - 825 (-200)

1188 - 875 (-225)

1350 - 940 (-185)

1512 - 1000 (-150)

Not necessarily. Higher frequencies on chips that aren't clocked at those speeds usually require more juice than the previous step.

Is the limit of my phone -124mv?
[Nexus 4 General] republitarian:
I would probably go to -100. You may notice artifacts or crashing in other apps later on and those settings may not work when the battery is low.
[Nexus 4 General] ngkongArm:
guys, is it really safe to UV our CPU? i've tried -100mV and it's stable (Carbon n Franco latest)

just wondering, is it really safe in long term for CPU or another hardware?
[Nexus 4 General] kishke:
Basically not all chips are alike, so the manufacturer puts a set value that should work with all devices. As long as your phone runs stable it shouldn't do any harm, on the contrary, it may help your phones life by reducing heat, stress on battery and degradation.
[Nexus 4 General] jiayit:
Mine was UV by 100, it ran stable but I kept losing data. My phone will reboot, then find that my app data is lost. Might wanna keep that in mind. I didn't realize it was my kernel until the third time it happened lol..
[Nexus 4 General] kishke:
I'm actually at some sort of a -175mv and everything is working great, no reboots or data losses.

If you want to see my UV check a few pages back, but keep in mind I got a faster binned chip.

then does it really affect on performance?

I don't think it affect performance at all, maybe only increases the time until thermal throttling kicks in by a bit. It's more for the overall healthiness of the phone na dbattery.

First thread, Yay!

I wanted to share with you a Theme for TWRP based on my new image from deviant art called Impact.

I am giving a lot of credit to JWhetstone02 as I mainly started from his theme and slowly but surely replaced as many icons as I could and changed the layout of some items.

If I could get some feedback, I would love to continue making these for every new image I come out with.

Instructions:

Open the TWRP folder and create a new folder called "theme" without quotes

rename the downloaded Impact-ui.zip to "ui.zip" and copy it to the theme folder

Restart into TWRP 2.4.1.0 and go to "Advanced>Reload Theme"

Enjoy!

Please notify me of anything wrong, I have only tested this on my DNA

I have also found the easiest way for me to test this every time I made a change was make a new ui.zip in my root folder and execute

"adb push C:\root\ui.zip /data/media/TWRP/theme/ui.zip"

Impact Alpha Theme is linked below, here are some mirrors:
