Wanna save some battery?
Have a look at this, my experience on undervolting my Nexus using Franco kernel:
Red - system not stable
Green - system stable and runs without any crash

the 3 minutes were tested under heavy duty - frequent task switching, video streaming and file system stressing. I'll update the document once I find any unstable voltages, so please come back for updates if you wish.
btw, everyone's phone is different, so the voltage settings may not work on all phones.
Here's what I've been using

If you wanna take the time to play with the voltages, you will get better battery life than using SR. I watched SR and it was running a good 75+mv higher across the board than when I underclocked it. Its been just as stable and smooth manually undervolting.

I was reading about few people showing undervoltages and stuff but I get really lost I dont want to mess up my phone.
I am running the lean kernel or imoseyon and I flashed it via the franco kernel app it has his kernel and the one I said.
Now I have no idea which settings to choose and which are safe... can anybody help me out?

Some people should only use SR, since they do not know how to uv, and troubleshoot that by themselves.

So, what's the point OP? Wonderful chart for your own use, but does little for everyone else.

Its a reference for others, not a "guaranteed to be the best voltages" chart.

I've used these as a good reference.
The voltages have been stable on my Galaxy Nexus. They are good to reference. In most cases the most I could undervolt from these settings was 25mV. So far, I've had pretty good battery life. I'll definitely vouch for houzuoguo's spreadsheet.
Anyone have real statistics and battery readings that prove undervolting is even worth the effort?
where is the test? i dont see any testing

I'll try to do some identical real world testing with my normal usage with Smart Reflex on then with my undervolt settings. I should be able to report back in a day or two.
The Results
Okay, so here are my results:
ROM: AOKP build 36
Kernel: Franco 166
Governor: Interactive
SmartReflex enabled
CPU: 192MHz to 1036MHz
Battery: Stock 1850mAh
3G on when screen is on with occasional LTE usage. Never used WiFi.
The first 3 attachments are without undervolting.
Attachments 4-6 show my undervolting settings.
The last 3 attachments are with my undervolting settings enabled. FYI, I used the saved values for the last 3 attachments.
If anyone wants anymore information on app usage just let me know. I have a few more screenshots, but didn't feel like uploading a ton of files.
I'm not sure if these results are sound, but I just updated to AOKP build 38 and Franco Milestone 4 kernel. I'll continue to test and see if these results are consistent.
Doesn't look much of a difference with doesn't it? according to CPU Spy and screen on time, as well as looking at 384MHz and 1036MHz CPU.
Thanks for the suggestions Houzuoguo. I am running LiquidSmooth-ICS-v1.5mr1 and Franco Kernel Milestone4
I took your settings and raised them all by 25.
I used Set CPU to set them and i also set the CPU to ondemand and dropped the CPU speed to 1036.
Are you using Set CPU to do this?
My Results
Thanks you very much BrandT90!! I tried some of you settings and changed some values. It's incredible. 11 hours!!! :good:
Look at the screenshots
ROM: Paranoid Rom 2.16
Kernel: Franco Milestone 5
Governor: Ondemand
SmartReflex enabled
CPU: 230MHz to 729MHz (but I use the schedule feature in SetCPU for Apps which need more CPU)
Battery: Stock 1850mAh
I set my brightness to automatic and tweaked the settings in cm10.
3G/Wifi: Juice Defender manages them.
Without undervolting I had the same results like BrandT90. (Look at his first 3 screenshots)

Thanks for these settings! I'm hoping this continues to get updated.
I just picked up my Nexus 7, and I have tinykernel installed, and I am now using trickstermod to undervolt my device. I would really appreciate it if someone could screenshot their undervolted settings just so I have something (like a benchmark) to go off of, along with an estimate of how much battery life I stand to gain by doing this. Thank you very much for any help!

Here are the settings I am running my Nexus on. They arent maxed out, I may get some millivolts here or there but its is at least stable. My GPU is running on -150mv
One thing to note is that I have an ACPU BIN 6 CPU.

Thanks, will try to give it a go when i have the time.
Did you notice your battery life improved vastly or were the results only marginal?
What do you mean? You mean you have a better binned cpu? How can i see my binning?
These are the stock voltages btw if anyone cares:

My best is 26777. I'm on latest Mahdi, using Demetris kernel and the optimized dalvik. I actually tested several times on Mahdi, then flashed the optimized dalvik and tested. Got a good increase. Then flashed Demetris' kernal and tested. Again an increase. Averaged 23847 on Mahdi, 25647 with optimized dalvik, and the 26766 after the kernal.

I usually use the optimised files as they have been the highest scoring for me, though I check with quadrant.
That score I posted above was running Art as I changed over last night to see how it runs and ran antututututu out of curiosity.
When I get a chance I'll switch to optimised dalvik and bionic and do a few runs.

24761 run once, on the V510 out of the box using the sleekai kernel. Nothing else is optimized on my device. I really don't know if the stock kernel would be any different. Maybe. They still ramp up to maximum cycles during the test. Stock default is Performance and CFQ, whereas sleekai default is On-demand and deadline. I do think the deadline is better at handling scheduler requests. I get a smoother scroll action I attribute to the deadline scheduler. Also a way better battery life.
I don't really think benchmarking is a good way of judging the performance of the device within a 5000 point range, but thats just my opinion, and may be wrong. If your cpu heats up too much during the test, your device will slow it down.
Edit* Newest Antutu Benchmark on the 510 out of the box using the sleekai2 kernel is 27052
As a side note, The gamma problem has been resolved entirely using this kernel. No more need for Trickster.

As I said in another thread , the secret sauce is this http://forum.xda-developers.com/nexus-4/general/4-4-4-4-x-qualcomm-optimized-dalvik-t2546120
I'm guessing the v510 doesn't need these libraries for its high score but we do.
It's all moot for me. I'm currently using ART, which scores in between the two when benching, but in reality I don't notice any difference between the three approaches in daily use.

whoamigriffiths said:
This is how I tested.
I installed Antutututu and quadrant.
I ran both several times to get base results.
Then I flashed the dalvik file and wiped dalvik and cache and ran both benching tests several more times and noted those results.
Then I reflashed my backup and right after flashed the Bionic file only.
I wiped cache and dalvik again, booted up and re-ran benches.
After noting those results I flashed the dalvik, so I now had both flashed. I wiped dalvik and cache again and ran more benches.
I've done this on cm11 and mahdi.
All the best rich
Just an addendum,
Whilst I have ran these tests, it has been for a bit of fun,
As I said in the Antutututututututututu thread, I'm currently running Mahdi and ART.
It scores around 4k less in antutu, but in practice I see no change in behaviour In my gpad.
I guess the gpad has enough power that the extra oomph that these files are supposed to deliver, is just a small ripple in real world use. Even if it's 4k in antutu.

Yeah, tried ART as well but didn't notice any sort of improvement. What i'm mostly after is solving the "thing" that makes UI animations a bit less then 60 FPS. It's more like its 30-60 FPS and one can definitely notice a drop here and there. My old Nexus 7 (2012) is more consistent in that regard and it's UI (stock, unrooted) actually responds faster to touch events which is a bit odd due to its old Tegra 3 processor and non-modded/rooted OS.

Ran a bunch of benchmarks. All in all it's way too inconclusive since the difference in average pretty much is in the margin for error (the highest average only differ around 1000 points from the lowest average).
I don't seem to be able to go beyond an average of 24.348 so it's odd to see some of you post scores that is almost 3000 points higher then that.
What could i have missed?

I would say your governor might be the cause : you are using OnDemand, have you tried swithching to Interactive ? In my experience, it would solve most of my stuttering launcher issues.
If you want better scores, you might wanna try Performance, but I wouldn't recommend it for everyday use.
I wrote a long reply last night and lost it so today I will do it again but a bit at a time
Ok as already mentioned I also prefer to use interactive and if the kernel allows then it's always interactive /row.
If row is not allowed by the kernel then I use deadline.
I would like to suggest that it's probably not just one thing that needs to be done, but a number of small tweaks that accumulate to achieve a better bench score.
Now some of these tweaks are only for benching whilst others will give you a zippier feeling tablet.
This would be a typical setup for me to bench and I'll point out which I used day to day to speed up my old N7.
First flash the dalvik and Bionic files (obviously not tried on the tegra N7)
After booting up go to developer settings and uncheck the three animation settings, then scroll down and check force gpu rendering. (this mod is good for daily use for a bit more zip, I used this on my N7 2012.
Next go into whatever app you use to adjust cpu.
Adjust the min and the max cpu frequency to 1.728 ghz (you may get reboots with the minimum set at this, so just dial it back slightly or increase the voltage value for 1.728 ghz)*this is most definitely not for day to day use *
Next go to the gpu governer and change the setting from ondemand to performance (I believe this has quite an impact and I reckon that it's a good one to try for day to day use)
It's worth spending a bit of time having a play with sd read ahead value.
I set mine to 2048, more from habit than any testing on the gpad. It is definitely the way to go on my phone but ymmv. This can be used all the time if you see a worthwhile difference.
To a degree I too stop some apps before benching but in the past I noticed if not careful this can be detrimental to antutu.
I use clean master for this as you can go into settings and modify the ignore list.
I think that is just about all that I do. I will update this if I think of something I missed.

Yes, with interactive i didn't notice better performance. In previous tests interactive actually always scored lower.
Sure - the performance governor can get better scores, but i'm not just after scores and ondemand or interactive should manage to score almost equal to performance when benching (within a 1000 point error of margin at least).
Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.
Solved!

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.

Okay, so I have had 3 android devices so far, and as I upgrade, each phone gets more advanced and there are things that are new to me. I've dealt with kernels in the past on the OG RAZR, but not to the extent of this phone. Now I understood what clock speeds were fine on the RAZR, but not one the One. Can someone explain to me the limitations on this phone? This includes clock speeds for this phone, GPU overclocking, which I've never done, and voltage settings, which I don't understand at all. I've never tried going this advanced into a phone because I've never had a phone this advanced really. I am currently running EclipticROM, which uses the Lunar Kernel. Any explanation or help is appreciated! Thanks!

Check your bin and PVS. The higher the PVS, the higher you can clock the cpu. Keep in mind, overclocking will drain battery faster when it hits those higher frequencies. Like my bin is 1 (normal) and PVS is 2 (not good for OC, but a tad better in battery savings) PVS also determines how low you can UV, but you will only see very little difference in UV (maybe squeeze a few extra minutes on a full discharge at the cost of possible instability just for -50)
