For all of you that have gained root access, I will show you how to dramatically increase your battery life
Step 1: Download SetCPU from the market or get its via XDA-Dev
Step 2: Install it and allow SuperUser.apk to gain access
Step 3: Leave the settings alone on the main tab. Should be at the top of the max bar and the bottom of the min bar with ondemand selected in the scaling.
Step 4: Check "Set on Boot" on the main tab
Step 5: On the Profile tab, check "Enable" and "Notifications"
Step 6: Click "Add Profile" and add the following profiles
Condition : Charging USB/Full
Max: High as the bar will go
Min: Low as the bar will go
Governor: ondemand
Priority: 50

What this will do is change your CPU usage depending on the state of your phone.
The phone will be allowed to run on full power when on charge if needed.
When the screen is turned off the CPU will run between 245 and 384mhz
When the battery is below 30% the CPU will run between 245 and 384mhz
You should find this will save a ton of battery. I have had ebuddy running in the background for almost 5 hours with 3G connectivity and my battery is at 72%
You can get more juice from your battery is you use JuiceDefender.
Also, remember to add SetCPU in your task manager ignore list!
Im a little fuzzy here. Where you have:
Step 5: On the Profile tab, check "Enable" and "Notifications"
Where is Enable? On the individual profiles or do you mean "profiles on" at the top next to "Notifications"?
Also,
Step 6: Click "Add Profile" and add the following profiles
I can't find "Add Profile" anywhere. I just have a bunch of preset profiles that I can enable and three of them are exactly the same??
I would really like to use this app so any help is appreciated
Edit: Never mind I figured it out. Thanks hope this will help with the performance

Profiles on would be the one. Mine says enable put it'll do the same thing
Once you have turned profiles on you will see an Add Profile button in the profile tab. Just add one with the condition i said and change the options
i've done it, lets see what happens. tomorrow i'll feedback. thanks
Wowzers im gonna try this out. Thanks!

whats the difference between this and overclock widget? i have that set:
screen on:
min: 998400
max: 998400
screen off:
min: 245000
max: 998400
basically same settings i had for my G1
Applied to mine as well, I'll come back tomorrow with results. I wonder what the device does by default in terms of CPU clocks though?

No because USB provides less "charging power" than a wall plug
I totally agree with max when the screen is on, but I set mine to total minimum when the screen is off. Background tasks when the screen is off don't need much CPU power.

are you guys shure that the rom doesn't have any scaling by default.... because my battery holds on for about 1 day wifi on and working with apps....?
HTC locked their stock kernel with a "perflock" to prevent users from underclocking the kernel. Well, good news is that a new function in the SetCPU app will now allow you to underclock your Evo and get you a real, tested increase in battery life.
According to my tests, my Evo with the screen off should theoretically get a 64 hour battery life!

Know what you're doing? Short version: Get latest SetCPU (version at least 2.0.0) and use Menu -> Perflock Disabler in the Main tab to enable underclocking.
Don't know what I'm talking about? Good, follow this tutorial:
Prereqs:
You need to have ROOT. Unrevoked root method is confirmed to work, and so is Toast's root method. Usually I wouldn't recommend using Unrevoked, but it's just so fast to set up, and perfect for those who have no clue what ROOT means.
Buy SetCPU from the market, or download it from XDA forums for free. Please support the developer of this incredible app! The version must be at least 2.0.0
Be on the STOCK kernel. If you're on a custom kernel, chances are that perflock has already been disabled, and you won't need this tutorial to underclock. Some custom ROMs come with the stock kernel (like Fresh 0.5.3) and some don't (like Baked Snack .9.6)
Alright, got the prereqs down? Lets start this.
HOWTO:
Open SetCPU and give it root permissions as necessary. As a control, go into the Info tab and do the Long Bench a few times. You should get around 1000ms.
Go to the Main tab, hit MENU, hit Perflock Disabler (read the warning!), and hit Disable Perflock Beta: May crash!
It will work for a while, and then say it's successful. You can then click the X on the top right to exit the Perflock Disabler.
Go into the Main tab and drag Max: all the way down to 245000 (245Mhz). Make sure the green xxx max xxx min label above the sliders show 245 for both and also disable any Profiles you've set. Go to Info tab, then hit Long Bench again. This time you'll get something ridiculous like 5000ms, meaning that the Perflock Disabler has worked!
Change your settings Profile tab to something similar to my settings. You can mess around with the Battery < xx% profiles to fit your needs. Your exact Profile priorities do not matter, it's only important that some have HIGHER priority than others. On the Main tab, set Max all the way to the right (998400) and Min all the way to the left (245000), Scaling to ondemand, and check Set on Boot. Do not check Set on Boot yet if you're the super careful kind. You can check it later when you've tested that your phone isn't crashing
Congratulations you're now able to underclock your Evo!
Comparison:
The only applicable parts is after the charging finishes (after the solid green bar ends)
Before Perflock Disabler:
After Perflock Disabler:
See that little dip at the end? That's when I was turning the screen on and messing with the phone for this tutorial. What a difference.
Disadvantages:
Yes, not everything is happy and pretty. As the Perflock Disabler warning says, you HAVE to apply the Perflock Disabler on every boot. If you forget, then your SetCPU settings will have no effect on the Evo. Install a custom kernel that already has Perflock disabled if you do not want to do this on every boot.
Also, since this clocks the Evo down when the screen is off, you may get a slight (super slight!) delay when you turn the screen back on. This is because the profile changes from Screen Off to Battery < xx% and SetCPU needs to clock the CPU from 245mhz to 998mhz.
FAQ:
What is Perflock Disabler?
HTC added a "perflock" in their stock kernels to prevent over/underclocking. SetCPU's Perflock Disabler, like its name implies, disables this restriction.
How come your screenshots show that you can go down as high as 1.19Ghz and as low as 128Mhz?
I'm using this custom kernel.
Will this work with OTA update xxx.xxx.xxx.xxx?
Yes, as long as you have root, and don't lose it when you update (do your research!) then this will work.
What are your settings?
Wifi ON, Bluetooth OFF, GPS ON, Mobile network Data OFF (ATT contract with dumbphone still not over), Screen Timeout 1MIN, Brightness AUTO, Advanced Task Killer Pro set to SAFE kill tasks when screen is off.
What is that cool looking battery monitoring app?
That's SystemPanel, paid on the market. A free alternative is JuicePlotter, also on the market. Screenshots were taken with Drocap2.
Thanks for this, I'll try this now.

Which version of SetCPU do you have? 2.0.1? Don't know if it's going to help, but try something in between 2.0.0 and 2.0.1 like 2.0.0b.
Does it happen only after you do the Perflock Disabler? Or does it happen every time you use SetCPU.
Try another kernel. There are tons. Maybe try this one that I'm using here http://forum.xda-developers.com/showthread.php?t=711964

Yea that's really bizarre. we have almost the same setup. Except I'm running the under-voltaged one.
Edit: Actually, that kernel already has Perflock Disabled by default. You shouldn't have to follow this tutorial. SetCPU should "just work" with your kernel.

I guess so. Since this custom kernel already has perflock disabled, you can use another app like OverclockWidget to underclock the CPU. Try it out and let us know maybe.

Nice, glad it worked out. OverclockWidget has very basic profiles, but they do the job. Any version of SetCPU should work for you, since you dont need the Perflock Disabler with that kernel.
ok, I got setcpu 2.0.0c and started doing the profile like yours, got to the second seting about the charge/full and saved, got the reboot...

Lol I don't know what to say man. Something's screwy.
Trying to figure out what the optimal settings for CM7 on the EVO Shift.
CM7 is a very advanced ROM that gives you control over a LOT of settings and it can be very hard to understand and frustrating to get the optimal settings.
Cyanogenmod 7 latest nightlies and change log available here:
http://cm-nightlies.appspot.com/?device=speedy
As of this time the latest "official" gapps is 828 and is available here: http://www.goo-inside.me/gapps
If you're feeling adventerous CrashV2010 has a new gapps with newtalk and market 3.2 included here:
http://forum.xda-developers.com/showthread.php?t=1311342
How to flash:
1) Get rooted with Clockwork recovery.
2) Download/Open ROM manager, flash clockwork recovery.
3) Reboot into clockwork recovery
4) Upgrading to a new nightly: wipe dalvik cache, /cache partition, /system partition, and battery stats
Clean install: Choose wipe/data factory reset and wipe dalvik cache, /cache partition, /system and data partitions anyway (just to be sure).
5) Partition the sd card how you like (wanna do this on first installs only usually, this will erase your sd card, so copy all necessary files off sdcard to computer before doing this and then copy them back)
6) Choose zip from SD card -> Flash CM7 zip file
7) Choose zip from SD card again -> Flash google apps.zip and then google apps new talk.zip. As of this time the latest gapps is 828 and is available here: http://www.goo-inside.me/gapps
If you're feeling adventurous flash CrashV2010's gapps zip located here: http://forum.xda-developers.com/showthread.php?t=1311342
7a) Flash a custom kernel if you have one.
8) Reboot phone
9) Wait 5-10 minutes for dalvik cache to rebuild and phone to load
10) Once phone boots skip google account setup and get connected to wifi
11) Menu settings -> privacy UNCHECK automatic restore
12) Menu -> settings -> accounts + sync -> add account -> google, sign in.
13) Open market: search for "pub:Google Inc." to find all the google apps
14) IMPORTANT: After installing GMail go to accounts + sync settings -> google account and check the gmail check box. Otherwise gmail will not sync!
15) Flashing a kernel: Download kernel manager lite from the market, open kernel manager lite, load kernel list, allow super user request, menu -> advanced options, uncheck "Automatically flash", back, choose AOSP kernel, download, reboot in to recovery of your choice (clockwork in my case, wipe cache, wipe dalvik cache, install zip from sd card, go to sd-ext dir, kernelmanager, choose kernel zip file and install.
You should be good to go at this point and you can start tweaking CM7 using my settings below or however you want.
At the time of this writing I am running nightly 224, Crash V2010's Google Apps with Market 3.2 and new talk included and Scarystable kernel, latest Clockwork Recovery, Patriot 16GB Class 10 SD card on Sprint. Also, using Google voice for text/voicemail and Launcher pro as my launcher.
I'll usually reboot once every day or two just to make sure it's working properly.. I blame this more on bugs in CM7 than the kernel. Then again I haven't run toastcfh's (stock) kernel in a long time.
4G works
Wifi works
overclocking works
phone is fast
battery life is good
ONLY use ScaryGhoul's governors. (SCARY, TOASTY, BATTERYSAVE!)
ALL OTHER GOVERNORS HAVE STABILITY ISSUES! (interactive, ondemand, performance, etc. etc.)
2 things to take notice of: There is a notification power widget (which goes in your notification/status bar) and a power control widget (which goes on your home screen).
What I'm really not sure about is which takes precedence over the other and what network modes to use.
Update 10-6-2011: I am ALMOST 100% sure the power control widget that you add to your home screen takes precedence.

^^This is wrong, you NEED auto-sync! And I don't know what code for strikethrough is obviously.
UPDATE: Auto-sync needs to be checked in order to receive gmail push notifications.
Background data is what apps like Facebook and Twitter use to sync data in the background.
In order to preserve battery life you should tweak the refresh interval in each application if possible. Other than that you are pretty much stuck with leaving both of these on unless you don't mind manually updating your applications.

=============================================
Explanation of governors:
Quote
From XDA-Dev & setCPU :
CPU governors control exactly how the CPU scales between your “max” and “min” set frequencies. Most kernels have “ondemand” and “performance.”
ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
interactive- The 'interactive' governor has a different approach. Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle. When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.If the cpu was not 100% busy, then the governor evaluates the cpu load over the last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down to.
smartass (Available only in certain CFS kernels. Not usually avaialble in BFS kernels like CM.): - Based on interactive, but better. Performance is on par with the "old" minmax and smartass is a bit more responsive. CPU spends much more time at the lower frequencies. Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more!
Scarykernel specific governor explanations:
Governor exlainations
Toasty makes one transition to the max speed and stays there(benchmarks only usually)
Batterysave! sits at the bottom and when the cpu load increases past the threshhold it scales up to the next speed and takes another load sample and keeps doing that(best on battery life/performance ratio)
Ondemand sits at the bottom and when the cpu load increases past the threshhold, it scales ot the max speed then takes another load sample and scales down accordingly
Powersave makes one transition to the bottom speed and stays there
Smartass(Quoted from another author http://www.ziggy471.com/2010/11/07/s...-governor-info ) - "is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works – by taking over the idle loop – is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the “old” minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!"
Scary - A new governor I wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.
===============================================
CHOICES OF KERNELS:
To download/flash a new kernel download kernel manager from the Market.
Differences between kernels are speed/battery savings/overclocking/underclocking/undervolting.
Right now I prefer ScaryKernel Stable. It is way faster than the stock CM7 kernel.
AOSP/CM7 based:
ScaryKernel SUV - ScaryGhoul
ScaryKernel Stable - ScaryGhoul
GirlyKernel - ScaryGhoul
V8 aka Pershoot - SparksCo
Tiamat_Shift - cayniarb
x99kernel-CM7 - x99percent
bcblend VR tinyRCU v - bcnice20
Official CyanogenMod 7 Kernel - toastcfh
You can use Antutu benchmarker (available from the market) to see the performance differences between the different kernels. I got over 4000 on Antutu with Scaryghoul's SuperStable kernel (which is available for download in the dev forum or kernel manager lite app, make sure you are on wifi before downloading through kernel manager lite) on Toasty governor at 1900mhz.
Your results will vary with performance. Not all phones can OC to 1900mhz and all phones will eventually get HOT running at 1900mhz constantly. There ARE different hardware versions of the phone. Mine is version 0004. You can check your hardware version ONLY with a Sense based ROM.
Sense based (DO NOT FLASH ON CM7!!):
ScaryKernel SUV - ScaryGhoul
ScaryKernel Stable - ScaryGhoul
Dodgekernel - dodgejcr
x99kernel-Sense - x99percent
Stock 2.2 Sense - Dodgejcr
Backups:
TITANIUM BACKUP OR BUST!
Please post your settings differences.. also if you could offer an explanation of the stuff I marked in ??? and which takes precedence the power control widget or the power notification widget that would be appreciated. Also provide the kernel you are running, nightly build number, and provider.

This is great!
Yeah just going to come out and say this, I didn't read all of it but you SHOULD/MUST take your phone off of toasty.
Toast is performance renamed. It spends all of the time clocked at the max speed....So you've been spending all this time at 1.9ghz. I recommend either dropping your clock speed down to 1ghz -1.2ghz or doing that & changing governors. Should never spend a long period of time at high speeds/voltages.

Updated the governor suggestion to Scary. I like having it at max CPU settings in case the phone needs to burst up to that speed.
In fact on either toastcfh's kernel or Tiamat's kernel Jesusice noticed that setting the max cpu speed to the highest actually improved his battery life. I don't know maybe it's different with your kernel.

Having the max set higher is not a problem as long as your phone is stable at that speed. Personally I don't like to go above 1.5 but each device is different. The problem is having the governor set to Toasty or Performance. With those governors you're not going just get a quick boost to the max when your phone needs it, it's actually gonna stay at the max all the time. Currently I'm using Smartass on Tiamat's. Scary can correct me if I'm wrong but I believe Smartass scales to your max when actually using the device but scales all the way down to the minimum when screen is off. I believe Scary is a modified version of Smartass.

Oh, and as far as performance settings I used to have purging of assests and lock home in memory checked and VM heap changed to 48 but lately I've gone back to the stock setting (unchecked with 32 VM heap) and I think I like it better. I've noticed no loss in performance and have noticed that Tapa used to require me to restart it frequently or it wouldn't refresh but now I don't have that problem. No comment on Compache since I'm not on Scary's kernel and that's the only kernel I've noticed that adds those settings.

Tiamat's kernel kept freezing on me. I could try it again soon sometime.
As of right now Scary governor + ScaryStable kernel has not frozen at all. Running good.
@Jesusice, could you take a look at the rest of the settings and let me know what you think?
How's about the data and sycn buttons? I turn off the sycn thought it'll save battery.

You can do that if you like, but I didn't really notice much of a difference..I find they are more trouble than they are worth and sometimes my sync stops working. The bigger question is notification power widget vs power control widget.. it's like 2 places to put in some of the same settings. Anyone know about this?

Using both the notification widget and the power control seems kind of pointless. Unless you would rather have the widget set for different toggles because you don't like scrolling the notification widget. I don't know...

There are settings you can change in power control widget that you cannot change in notification power widget settings. Add the widget to your homescreen and see for yourself since you ARE running CM7 after all.
Most of the settings you list are subjective and there's not a "best" setting or "better" setting. So, I'll just go over some of the settings that I have enabled and enjoy.
This is how I have my homescreen and power widget set up:
I don't have 2G/3G toggle enabled because I don't believe it actually does anything on our phones. I wish it did though. And I don't think you have to worry about which widget (power or status bar) takes precedence, they work together. For the status bar widget I have my media controls (prev, play, next) and my torch.
I've been using Tiamat 1.1.2 since release and have kept all performance settings at stock default. 1ghz max w/Smartass governor. I also use AutoKiller Memory Optimizer set to Optimum preset (40, 50, 60) with all the Advanced System Tweaks enabled except "Remount all partitions as noatime". I did have that enabled for a while but then I noticed that when using Gameboid it wouldn't keep track of my quick save correctly.
For me, the beauty of CM7 is in CyanogenMod Settings. There's just some small tweaks available that I don't think I've found in any other ROM that's not based off of CM7. (And I don't feel the need to use a ROM based off of CM7 when I can just skip the middleman and use CM7.) For example, long pressing volume keys while screen off to skip tracks is freaking awesome! (Big up to Bobtsunam for enabling it on MIUI, thereby removing one of the dozens of reasons that prevent me from using MIUI). Also, incoming calls in the background is genius. There is a small bug with it when using apps that exclude the notification bar since it locks the home button but otherwise it's awesome sauce.
If you turn off auto brightness then you can slide along the notification bar to adjust brightness. The long press action for Home, Menu, and Search can all be customized to open whatever app you want. I have my Menu set to bring up Subsonic when held. Whenever I want to leave an app that doesn't provide an easily accessible exit button I just long press Back and BAM!, app killed.
Oh, and I've also been using ViperMod and lowered voltages by -50mv yesterday and haven't had a problem yet. It may be a fluke or because I just wiped battery stats at 100% but I've been getting amazing battery life today. About half and half on wifi and 3G with moderate usage I've gone 7hrs 15mins and am still at 66% =)
I am on nightly #178.
BTW: To any new users reading this, you really shouldn't even bother with the CM7 RC for the Shift. That thing is way behind the curve. I know it's the only CM7 posted in Development but you should really check out the nightlies. 178 is my recommendation. The nightlies thread is in General if you have any questions.

UPDATE:
I found that you DO need the Power Control WIDGET on the home screen. I was having problems after turning off switching from Wifi to 3G.
Still researching 4G/3G, updated some other settings.
updated, changed allow purging of assets to be unchecked. better performance.
THANKS!
Thank you Vico! It was a pleasure to meet you the other night =)
I am still trying to figure out if they have a Voicemail app that works well now..

I google it but i'm not understand very well.
What is intelliplug? It is a type of governor or a improvement for governors?

first you have to understand what hotplugging is. this is my understanding. hotplugs are used for screen off and on cpu usage. example: when the screen is off the cpu only uses a certain amount of cores. when the screen is on it uses all the cores. also it reduces the wake time of your device by ramping up the cpu frequency to get a faster response. they reduce the on screen lag. this was introduced by qualcomm with mp-decision. but mp-decision is a little aggressive.
intelliplug is a hotplug replacement for qualcomms mp-decision. it's supposed to be more "intelligent". it has a set of parameters that's usually not tweakable and set by the kernel. this is why you normally can only enable or disable it. you dont want to use mp-decision and intelliplug at the same time.
hope this helps.
Hi.
I am looking for pretty long time for a method to disable "Touch Boost" feature on MTK SoC or any way to force lower frequency while touching the screen.
I want to do this, because on low load i am having "temperature spikes" because of CPU frequently jumping between lowest and max frequency and thos feature is pretty useless with custom kernels.
I haven't found any parameter in "system" folder on stock or custom ROM with "normal" kernel or Tensei kernel

Hello there, you could try an kernel manager tool. It would be able to trace the function you are searching for, otherwise try for this path: sys/module/cpu_boost
No "TouchBoost" options in: Kernel Auditor, Device Control, EX Kernel Manager, no "modules" or any trace of "touch boost" in root folder.

then what makes you think you have it? LOL
Yes, i see it in "cpu monitor" charts.
Screenshot- Low CPU load, only touching the screen.
