1. Dont set any of them higher then 1075. I've found that on multiple HD2's that higher then that causes instability because the chip doesnt like to be pushed that hard.
2. I have my primary profile set to 1075 max, 614 min, and getting good results.
3. Set your primary to interactive, and all profiles to interactive EXCEPT your low batter profile.
4. Add these profiles:
Temp >
Charging/Full
Batt < then
Screen off
-Temp > Set the temp around 40 degrees C. Set to interactive. Max around 576, min to 245. Reccommend auduable warning on. Priority to 100%
-Battery <. Reccomend you set to around 30% battery. Powersave mode, max around 576 or so, min at 245. Priority at 90%
-Charging/Full Max to 1075, min to somewhere in the 500 or 600's, or higher if you want. Interactive, and Priority at 80%
-Screen off. Set max to 576, min to between 300-450. DO NOT set min to 245, as this may cause a screen freeze when it tries to wake up. Interactive, and priority to 50%
Thus far, this combination of settings has, on the multiple devices i've been playing with (about 6 total at the moment) is giving the best battery life, and the least amount of screen freezes on wake up.
Thanks for sharing these. AFAIK setCPU is quite important to the stable and productive (sans improved battery life) of Android on our beloved's.
Personally, I've taken to 245/245 for sleep mode. I haven't noticed a "groggy" wakening, but maybe I'm alone here...otherwise I like your settings.
Thanks again for taking the time to post.
android can run perfectly at 650+ mhz max, 245 min

I used to use 245/245 on sleep, but noticed a 4-5 second delay on one of the devices.
Actually, that may have to do with your SD card itself. my phone (running Bangsters 1.3b build) has a rare delay on awake, and a class 4 card.
Another HD2 running darkstone has a consistant delay, 245/245 and its running a class 6.
And still another has no delay, and is set to 245/245 but the stock non-speed rated SD card..
I have constant screen freezes on any build i use. bangsters1.3b has the lowest. it only freezes when i am in a phone call and the screen turns off. It lasts for about 15 seconds to 1m. then recovers. makes for some interesting post ended phone call conversations.
Trying your settings, MadRabbit.
Will give it a try, thanx
Should be better if we post our impressions so far within 24 hours

Yep, that way we can find tune the settings for what works best.
ill give this ago i dont tend to get slow wakeup problems but i do how ever get screen freezes so hope this helps as when i playing a game it can make it really hard to attack people when screen isnt picking up my figures
What exactly is the interactive governor? And why not set the mins to 245 so the processor is scaled down when its not being used?

Minimums may cause an issue with the phone when it wakes up from sleep, especially if you have a higher class memory card.
I've noticed that my usual drain became slow during last hour, I'll report better news tomorrow, leaving device in stand-by at 69% battery left.
Ok, i didn´t think i was that stupid at this but now i don´t know anymore
I´ve searched both in andoids market and on the XDA app on the phone but i can´t find the app setCPU.

thanks man! just tried your setting, and then used current widget to check : 4mA when the phone was in sleep mode. This is the lowest result i've ever have ( i got 7~9 mA before)
ive ran this setting today and battery its definitely draining slower... ill report in a few days of using these settings...
I use it until this morning and I find that very good.

Hello,
This is something I do want to share for people who has problems with the battery drainage. I don't have the intention to know it all, and I am not a developer. I'm just happy XDA user.
Like most of the users here we all like Android on our HD2 but the battery drainage can be annoying. I searched a lot threads for the right settings with SetCPU etc.
One day I was fed up with it and installed a new ROM, new radio, new kernel and a new Android. See my signature which versions (also for download).
All I needed to install again was SetCPU. On the Android market I found a program called CPU Tuner. So I installed it and looked what I could do with it.
There wasn't really much to adjust, but weirdest thing of all is that the battery drainage is really minimal. I send some textmessages, had a few phonecalls... Surfed the net for like 15 minutes. My Wifi and 3G are on all the time.
Please don't ask me how it's possible, but I thought just to share it with you.
Here are the settings of CPU Tuner:
Tab Current
Governor
interactive
Max 998 MHz
Min 245 MHz
Tab Profiles
I have 3 Profiles
1st
AC Power
Interactive
Max 653 MHz
Min 245 MHz
2nd
Battery Power
Interactive
Max 768 MHz
Min 245 MHz
3th
Critical Battery
Interactive
Max 691 MHz
Min 245 MHz
Tab Settings
Got "Enables Profiles" switched on
Got "Start on boot" switched on
Got "Statusbar notifications" switched on
Got "Toast notifications" switched on
So it looks like setCPU a lot but can't change settings that much.
If you got any questions, feel free to ask and I'll try to answer them.
grtz. Sander
I dont have the interactive option on mine... just indemand and others such as powersave.... but no interactive. What should I use?
Also what is your current widget drainage showing?
Is your phone rooted? And which kernel do you have?
If you have a rooted phone and Hastarin 8.1 kernel, you should have the option of interactive with CPU Tuner (also with SetCPU).
Do you have a widget for me to measure my drainage? I will let you know if what it is...

Use CurrentWidget on the market.
With my current setup (VBNROM Reloaded 2, NexusHD2-FRG83 v1.6, hastarin 8.1 kernel, 2.15 Radio) I've found the only way to get consistent <10mA idle is with setCPU and Tasker. I understand that setCPU is supposed to be redundant with the newer kernels, but without it, my phone drains in the 20-30 mA range. I only use a screen off profile on setCPU, 245 max. That's it.
I've also found that GPS tends to really drain the battery when the phone isn't using wifi for location. Tasker (available for $$ on the market) is great for this - I set it to only turn on GPS when I open maps or navigation.
Also -- searching for wifi seems to also drain the battery, so either turn it off when you aren't using it, or set wifi to sleep when the screen is off (settings --> wireless & network --> wifi settings --> [menu/start button] Advanced --> wifi sleep policy).
I use Shubcraft 2.0, with the ElBartoMe kernel (no overclocking, or undervolting as far as I'm aware) and NO setcpu at all, my drainage is <8Ma on average in standby and my battery lasts about 20 hours with what I would call moderate usage (about 2 hours a day listening to mp3's, at least an hour on the phone, 3G permanently on and syncing every 30 mins for facebook, gmail etc and about an hour or so gaming as well. Even at the 20 hour mark I've still always got about 15% left anyway, I just leave it to charge while I get my (very little amount of) sleep.
I've downloaded currentwidget and I will keep it running from now on.
I had it set on refresh every minute
operation on value "none
Checked Write to log file
Checked Log running applications.
So tommorrow I will share my log file. Maybe you people can get more info out of the file
I use the new MDJ S2 kernel with the smartass governor.
It has the CPU profiles built into the kernel, so you don't have to use any SetCPU profiles, and it extended my battery life by like 2X, it's pretty amazing, I was on hastarin r8 before.
I recommend you try it out.

So if I'm right, the latest kernels have already the right settings built in?
Like Hastarin 8.1 and the MDJ S2 kernel...
And I was thinking that I found a solution by accident
I have created a log, but I have logged it from minute to minute.
So if you are interrested I will place it.
For now I chanched it to every hours so it will be easier.
I downloaded the cputuner but cannot find the governor "interactive" on the list. Is there another one that would work?
Hey,

Just one simple question. When phone is in deep sleep, the cpu's running speed is the min frequency I choose from the cpu settings or a default lower one?
I use smart ass 2 with min at 768 and max at 1516 . So in deep sleep my phone is running at 768?
Thanks in advance...

Not 100% sure but freq is minimum as it can be. And if cpu is not used no metter is freq 10000MHZ or 300Mhz it uses almost the same power. But when cpu is in use freq is important to power usage. Freq management is good not because it lowers freq but because it lets use lower freq on things that is not require hi freq. so it saves LITTLE LITTLE BIT of power. In idle mode (deep sleep) no meter what freq is.
But i still don't understand the need of governor. It's good only in cases where you overclock cpu but if don't - i don't see why it should be used.
PS Use app called CPU SPY it shows on what freq your cpu is being used and how much of the time.
Thanks! I use CPU SPY and it says tha about 60% or more is in deep sleep, 15%-25% is at 768 and the rest higher, which seems to be a good thing. But my phone still lasts for about 10-15 hours with normal use.
So i thought that maybe my min 768 frequency drain a lot of battery.
To clear things up a bit I use latest oxigen rom+latest franco kernel+zram+Juwe ram script...
Actually deep-sleep state is a special state supported by your phone MCU. In this state, a lot of functionality (therefore a lot of logical gates) are disabled thus MCU consumes very low power compared to normal functioning states. The thing about a CPU/MCU is when it is running even if there are no work to do no code to process, it has to run some command. While idle it must run NOOP (no-operand / no operation) command or do something equally unnecessary like counting a not required number. But in deep sleep mode, MCU actually stops working except for core functions to keep your phone going on.
Think about it this way, in a normal working state, CPUs most basic functionality is to read a command from memory, execute it and proceed to the next command to continue. Thus, in an operating system or a single purpose embedded software, CPU/MCU has to execute a "do nothing" command when you have no job to give it. But even a "do nothing" command need all of the MCU/CPU resources to be kept readily available. If you're sure that you have absolutely no job for your MCU/CPU to do, what you can do is to tell it to go and sleep fr a while until you wake it up again. In sleep, MCU/CPU can shut down a lot of its support systems like math processing, external memory access, graphics related functions (if any), even IO outputs. Depending on your CPU/MCU, this means until an interrupt occurs or a special sub system wakes it up, most of the sub-systems within your MCU/CPU thus may be millions of transistors will not be working so, your CPU/MCU will not consume as much power.
In layman's terms, deep-sleep state is a special state that shut down most of your MCU in your phone, thus while crippling it by removing its ability to function, making sure that it doesn't consumes much power. So OS (Android) (with the help of some additional hardware) controls when your MCU will sleep and under what circumstances it will wake. So it shuts down the engine -so to speak- when you're not using it for long terms and saving fuel rather than leaving your car on idle.
Hope this helps..
Thanks t_d_z. That is also how I imagined things...
But what is wrong with my battery which today, for example, went 33% down in 5 hours with 68% (from cpu spy) in deep sleep, without wi-fi on.
As i said above, I use latest oxigen rom+latest franco kernel+zram+Juwe ram script+smarass2 governor...
I also calibrated my battery by wiping battery stats, like i read in a post.
I have read in an other forum that if you use smartass (I use smartass2) or ondemand (I think...) governors, the governor is learning your habits and after a week you see the difference. Is that true?
Finally, can you guys who have "good" battery life, post your settings? (By settings I mean: rom, kernel, governor with cpu parameters, how you use the phone and everything else you think is important).
Thanks again...
I get about two days of battery life. I use Oxygen without any modifications. CPU is min. 245 (or something like that with 200, I dunno now) and max. is 800. Wifi is always on when I am home.
Try installing Oxygen-r1 and use it with a full battery, do not change anything and do not install too many apps. There will be apps that just won't stop running (like BBC or CNN app), I do not install those. Then you will see how long your battery lasts. If you just write some messages throughout the day and call somebody for 1-3 hours you should get about 2 days.
Then install your apps and test it again - maybe your apps are the problem.

Look not at cpu spy but in battery usage to find out what drains your battery. And i can tell All roms are kinda lame in terms of battery, except CM7. In deep sleep it takes about 7% of battery in 10hours. I tried all roms but non of them was so efficient. But latest franco kernel (which i think even more improves cm7 rom) does not support cm7 right now, so i've attached older version if you would like to test cm7+franco kernel.
With normal usage of 50 sms and 30minutes of calls and sometimes wi-fi to download few apps and 20minutes on easy games my battery lats about 18hours. Whan only sms it lasts 30hours. depends how long lcd is on
Well, I'm not an expert on smart phone OSes but I'm an expert on embedded systems and micro controllers. If the designers are not really stupid (which I'm sure they are not) all the peripherals gets suspended when the main CPU goes to deep sleep mode. So, it is almost impossible for the phone to consume much power in deep sleep state. Most likely your phone consumes that power the rest of the time when it is not in sleep mode. I agree with Tommixoft, you should use battery usage info rather than CPU spy to find what drains your battery. Also, here is a quick check list about what consumes power :
1. Screen, especially when it is brightly lit
2. GSM network (Even when you're not talking to phone, GPRS/Edge/3G network communications drains almost as much power)
3. Wireless network
4. GPS
As an additional note, if your phone is not going to sleep mode regularly try to uninstall applications that have "prevent phone from sleeping" security setting.
Hope this helps, and of course there are a lot of more experienced people in the forum that knows about the details of the kernel so they might provide additional info.
Regards,

Oh I forgot to tell the MOST important thing, 768MHz is way too high a value to set as minimal frequency. Try to set it 245. I use 122 MHz and it work pretty well. Don't forget, when you need the CPU power, the governor will provide it for you.
Hi and happy easter to all, thanks for your fantastic works on HD2. I always asked to myself which is the SD-rom that preserve more battery and which are the "must have" programs that keep the battery alive . This is my first problem on HD2. (the second is the video lagging, but I can understand that HD2 processor is not so fast..)
Thanks
Should be moved to Q&A
Video recording on CM7, MIUI and Sense 2.1 downwards ROMs is stable and smooth, and for the battery first check what kind of drain you're getting.using the application CurrentWidget . On airplane mode it should be no more than 3ma (probably 2) so if it is then you have quite high drain. I personally use the profiles features of SetCPU and JuiceDefender and get an easy few days worth of battery if I use it very little, and even with a few hours of listening to music on the bus I still have 70 percent battery at the end of the day.

For your setcpu issue, make sure that you aren't setting the frequency when screen is off too low, set it to something like min 245 Max 576 with the scaling as ondemand. I really didnt do anything with juice defender, just installed it, set the main scaling thing to balanced and let it run

Disclaimer; This does not damage your phone at all or fry/mess your cpu.
This method is used to lower CPU stress and increase Battery life
This method works for all rooted phones.
IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.
LINK
Deep Sleep breaks when charger is plugged in, you can see this by CPU SPY application available on playstore
Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:
Also Turn BLN off when you are sleeping.(It also Consumes battery and sometimes prevent deep sleep of CPU)
Set your Brightness to minimum and disable auto brightness.
LINK to Display Brightness
Instead use lite app called - Display Brightness from play store.
Turn off wifi and mobile data when not in use.
Use toggle for auto rotation, and keep off when not needed.
For more battery Saving, disable all animations and set screen timeout to 1min.
The S plus sucks in battery life. We all know that.But here's a fix, Try Under clocking instead of Over clocking.
When screen is on:
MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)
MIN 192Mhz
Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 365 Mhz
MIN 192 MHz
(This prevents lagging when playing music and other activities when screen off)
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!
NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do.
SetCPU:LINK
Specific instructions for those that can't get it to work!:
On SetCPU:
Click Add profile
Where it says Profile, select it and tap "Screen Off"
Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)
Set priority (in case you have other profiles, otherwise don't bother)
Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)
Tap save
Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.

To check if its all working, install CPU spy from the playstore: LINK
For Playing GAMES(HD)/HEAVY GAMES, Plug your Charger in and play if possible.:good:
Most Important thing is to calibrate battery,
Calibration of battery is needed when you change your ROM.
This process wipes batterystats.
Battery Calibration
1. Charge 100%(NON STOP)
2. Download any battery Calibration tool from play store; (Link to App)
3. Open that app, click battery calibrate
6. Unplug your charger
7. Discharge your phone down to 0% during the day
8. Charge back up to 100% (NON STOP)
This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.
The worst battery killer is 3G. No matter how much you try to optimize battery by tweaking and underclock, if you have 3G on, you're gonna have a bad battery drain.
Make sure that Autosync is disabled.
Done A small test usage 14 mins , you can see in attachment your CPU should look like this.

Nice advises. I'm already using these.
One more good thing is turning mobile data off whenever you are not using it, also bluetooth, lowering brightness.
Good app for doing so is Power Toggles. You can always have widget on home screen and switch on/of these things with one tap.
Riiight.. Turn off autosync, disable 3G and wi-fi, dont use apps or games.. I might as well buy Nokia 3310..my phone lasts easily whole day with wifi on..with 3G it can get me at least 6-9h which is fine.. The key is to turn off 3G when you are on wifi and turn down brightness.. Everything else is not using your smartphone smart..
1) Set your network mode to 2G only if you're not using 3G/WCDMA
2) Manually set your operator in settings.
PS: After flashing one of firmwares I got a bug - battery is not charging to 100% while phone is ON. Only to 99% and not showing a message about fully charged battery... But when the phone is in off mode - it charges to 100%. Anyone knows how to fix this thing?

But it has no profile-autoswitching, in fact no profiles at all. Voltage control Extreme has at least profiles, but without autoswitching. What is good about Voltage Control Lite/Extreme is that it sets cpu setting with init.d and so the app does not have to start on boot

MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)
MIN 192Mhz
Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 365 Mhz
MIN 192 MHz
(This prevents lagging when playing music and other activities when screen off)
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!

Many thanks for the battery saving hints. I'll finally kick out the Task Killer App, doesn't really seem to do anything except creating problems ..
For the statement that Underclocking would help in saving battery I wouldn't fully agree. A slow cpu needs more time to complete a task before returning to a sleep state. Of course the battery drain is higher with a higher frequency (which also require higher voltages), but I believe, that there isn't much to gain on this front. As long as I don't see any profound evidence I'd even suspect, that an underlocked CPU overall could even cause more power consumption. You can also read more opinions about this in general in this thread.
Much more beneficial would be to identify those apps that cause frequent wakelocks. Does anybody have hints here, how to track down those 'bastards' ? (From my Linux I know 'powertop', does something similar exist for Android? (Or are the battery statistics in CM10 sufficient to decide which app to wipe?)

Better battery stats is application useful for identifying partial wakelocks.
Its an paid app, but Google helps... Lol
Your above sentence about UC comes true for heavy usage.
Normal apps can run smoothly and at same speed as of OC.
