currently working on finding minium stable voltages....found some pretty low settings to work...but when unplugged....got sleep of death so im trying to find the balance.....Once i have a solid balance...ill test battery life at 1.9 and 1.7 which are the 2 frequencies i found the most difference between in Antutu....
also trying to toss CPU sleeper in the mix....i dropped the app when i got Sleep of death thinking it was that....but it was just too low a voltage....Ill keep people posted once i have solid results...

A message to all you devs out there- I'd love to see an app made for the note 2 that auto-tests voltages to find the lowest stable number for your individual phone. there were a few apps like this for my old droid x that worked great.

I used this app that would give error if the CPU is receiving insufficient power from UV too much https://play.google.com/store/apps/details?id=com.into.stability
A cpu stress test is also built into the SetCpu app

I have had exceptional battery life using BEASTMod.
Just my opinion
they are all good imo, im currently using gingersnap rom, has the faux kernel and i get over 20 hours of some what heavy use, and so it went with juggernaut, beast mod, and bombardier.
but the faux kernel has proved to be smoother and more efficient imo, perhaps slightly better battery.
hope i could help
I like Juggernaut + Bullet.
I am trying to make the most of my battery by:
-underclocking to 384-16xx
-turning on Battery Saver
-running Juice Defender
Anyone know how to undervolt on Bullet?
I am a heavy battery user. I use my phone all day constantly on Netflix (through Wifi) and listening to music with web surfing. I get about 16 hours on it everyday and come home with 4%-30%. It is very odd on why my battery percentage is such a big range. Screen is on like half the day. I really can not complain about this battery.
I am trying to figure out the best setting on tuner pro for dewizzed 2.0. I am only getting like 6 to 8 hours on my phone. When I've seen others get close to 24 with light to moderate use. The rom is Dewizzed 2.0, and I know the some people have the same rom while using tuner pro. I would ask the dev in the devolpment section, but I don't have permissions to do so. Also Hello everyone in xda. I am a long time visitor since the G1 days. I made this account a long time ago, but recently got tired of touchwiz, and decided to give it the boot lol.

I am running Dewizzed 2.0 with Synergy kernel and using System Tuner Pro, 1.62max 384min, 384max and 192min with screen off and am not UV because Synergy is already UV. Getting well over 21 hours of use, light to moderate usage,
Sounds like you have a app that is using a lot of battery.

I noticed a bit of lag when I first flashed Beast Mod w/Synergy. Try this before you flash, it worked for me and my phone is buttery smooth. Boot into recovery wipe cache 3 times, wipe dalvik 3 times. Then go into advanced, then mounts and storage. Format system. Flash synergy, then fix permissions. Reboot, enjoy. Also Im running zepplinrox's V6 supercharger script. That helps out with smoothness too!

Undervolting

I wanted to know some more about undervolting and was hoping someone could help and explain a bit. Basically, what I'm seeing is when I undervolt my device on the max side of things, eventually the device freezes and needs a battery pull or reboots. When I don't touch the max voltage values and only drop the min values the phone seems more stable and doesn't reboot. Can someone explain if my thinking of only undervolting the min values is correct and why this may be happening. Also, what would be the proper way to undervolt the phone? I have been using system tuner to do so on deck's 1.3 ROM using the Lee +sbc kernel. Thanks for taking the time to read this and for all the helpful responses.
Sent from my Decked Evo running Lee+sbc... It's easier this way.
I have this same question! I was trying to figure this out becuase the freedom kernels have something to do with under and over voltage to allow better OC? not sure on why the you would need and over voltage to over clock?...
What is your ROM/Kernel setup?
Remember that undervolting and underclocking are two different things. Over/underclocking, via apps like setcpu, raise/lower the frequency at which your processor operates. Over/undervolting raises/lowers the power voltage available to your processor at any given frequency. This can potentially cause problems if you have a kernel set to undervolt your processor while running an app like setcpu to overclock it. This may be why you are seeing issues with your phone.

OP clearly states he's running Deck's 1.3 and Tiamat 3.3.7 (aka LEE kernel)
OP should also state Deck's ROM version but I'm assuming 1.3d as it's most popular next to 1.3 Stable.
I'm running the same setup - Deck's 1.3d with LEE SBC. I'd like someone to explain (as the OP also asked) the difference between the MIN and MAX sides of the undervolting equation please.
(I do understand underclocking AND that it is a separate and different animal and for the record, my EVO is UC'd to 128/499MHz and using Smartass governor)
I'm just not sure what I'm looking at in the ST interface (what's the first number and what's the number in [] brackets?) and also not sure just why there is both a min and max voltage for each frequency and how it affects performance.
Thanks much for any inputs.

I use vipermod and terminal emulator for aosp roms its much more stable than using system tuner and you can drop all voltages with a single command it all depends on your particular hardware but typically around -100 the phone will lag or freeze i usually stick to -50 at stock voltages and -25 on overclock i never overclock over 1075mhz as anything higher and my phone tries to cook my fingers however now im oc to 1.6ghz on my et4g with a 200mhz min and it stays nice and cool like it was clocked at 1.2ghz stock the exynos is capable of clock speeds up to 2 ghz but the phone doesnt handle those speeds well similar to the evo not liking anything over 1.19 at 1.2 on the evo theres a good chance of frying the logic board or bursting the battery from heat if you overclock dont undervolt too much as it makes the processor get really really hot due to it having to work harder from lack of energy to power it

To answer the min/max at each freq min is the lowest voltage that freq will run while idle max is the highest voltage the freq will run while in use the voltages are depenedant on the load running at the particular freq ie how many process' are running the more process' the higher the voltage required to power the processor

I had a similar issue with undervolting and underclocking. I was setting my CPU min/max to 128-499 MHz and undervolting to -75 or -100 using Lee with Smartass v1. But I was getting too many random reboots and freezes on each ASOP rom I tried (e.g. Deck 1.3d, CM7).
I've been playing around with these settings. I changed my CPU to 128-576, no undervolting, and SZ 2.2.1 with SavagedZen governor. I haven't had any random reboots and my batter life is about the same...plus my phone is MUCH snappier. I'm still getting a little screen on lag but not nearly as much as I was at 128-499 and undervolted.
As a note, I normally run Deck 1.3d as my daily driver but for the last couple days I've been running KWIQ. It's definitely giving 1.3d a run for its money as becoming my daily driver.
Anywho, are there any rules of thumb with undervolting and underclocking? Like is 128 MHz is too low with -100 undervolting? Or are these things pretty much phone dependent? I know each phone seems to respond different to these things.

Thank you. That made good sense to me. Question then: is it suggested/typical to drop min and max by equal amounts or is it typical to drop min more (so there's juice for the proc under load but maybe being more aggressive with the sleeping/idle side of things or can the proc run at a given frequency at different voltages)?

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.

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

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)

[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

[Q] CPU Temperature exceeding 80°C! How dangerous?

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!

Does not exceeds to 80c now?
You can try a custom kernel, i would recommend you BioShock kernel, with conservativex, max freq 2.2 ghz and undervolt 25 mV... No more over warming for me, great performance and battery life

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.
