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.

From 69% at 12.15 AM, battery dropped to 61%.
That's what I've seen when I press the home key at 6.45, cool :;
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.

Thanks a lot
Thanks! I will try your settings, mine were a little off and gave me 45mA in standby One question though, what sample rate do you use? mine is still default (50000).
I have setCpu 2.03 installed but i can't find the Interactive setting?
Where is it, or do i have the wrong setCpu version?

Hey guys, I posted these settings in the main thread of darkstone, and it worked good for some, i'm making this thread to show the setting i'm using to conserve bettery.
I have been using Setcpu and advanced task killer combined and so far my battery life is amazing. I had the phone unplugged and fully charged at around 7 pm, used it for few calls and some gaming and also downloaded some apps, it was at 70% when i went to sleep at 4am, now it is 10 am and the battery is 66%.
You need SetCpu, you can get it from here http://forum.xda-developers.com/showthread.php?t=505419
And Advanced Task Killer found on market for free.
I thought I would share those settings hopefully they work for you guys too,
For SetCpu:
Main Tab: max 1113, min 245, ondemand, check set on boot
Profiles: 1- Screen Off, max 245, min 245, ondemand, Priority 100
2- Battery <25%, max 652, min 245, ondemand, Priority 0
Advanced: Sampling rate= 20000
Up Threshold= 35
leave the rest at 0's and check set on boot and apply.
For Advanced Task Killer:
Go to setting, then auto kill level chose "aggressive", and auto kill frequency set it to "when screen turns off"
I'm using radio 2.12.50.02_2 and stock Tmobile US ROM HSPL3
I hope that helps some of you.
I've had major issues with battery drain. The best I've got so far is about 5% to 7% drain per hour on standby.
I'll try your recommendations too.
Battery is the only thing holding be back from using Android as a full time OS.
Do you charge your battery in Android or in Winmo?
got settings from other thread, thought they were working well turned out they were not lol had to jump back builds
Battery life is keeping these from being fully usable. I can't make it through a full day, I have tried juice defender, set CPU (max fre 800, 245 w/ screen off), turning sync off. I always get at least 5% drain/hr at idle and obviously worse than that when I use the phone.
I am going to charge overnight tonight in win mo then boot android tomorrow morning and see if I can get through the day tomorrow.

Ok let me know if these settings work for you.
I have the same config in this build
[BUILD][17.08.2010][mattc Leo + Froyo w/Sense 1.5b][Kernel: huanyu 2.6.32.9 #6]
and it is working well even there!
I hade 11 hours down to 15% left of battery yesterday.. and I hade it on surfing by wifi and trying some new games and hade a lot video streaming through youtube the last 2-3 hours.
Before I couldnt last for more than 3-4 hours and the phone got very varm....so this i a start and a very usefull app to use!
If you want to extend it further turn of "data connection" at the point you know your not gonna use the phone for a while.
@Notorious.Marwan, won't having setcpu at 1113 for both max and min be draining the battery more as opposed to having it at 1113 for max and 245 for min? or would the difference be not noticeable at all?
Notorious.Marwan, those settings will not be very good for battery life.
You have max and min set to full clock speed...this is going to use a lot of battery power.

I am going to try this.....I was on Darkstones HD2Froyo without setcpu and batterly lasted only 6hrs maybe even less.......
Now i am using Mattc-NexusLeo_v1 build w/ the lastest kernel, used the default or suggested setcpu settings from one of the xda members and i am never at full 100% only 99% or 98% and gives me about 8-12 hours of batt life.
I will try your settings and report back in 24hrs with an update, thanks again for the info!

Also too...Something that I missed at first...In the Advanced Task Killer settings...you have to ignore SetCPU or it will kill it when you turn the screen off and defeat the whole purpose.
Still ridiculous battery drain. 99%->93% in 27 minutes. Using mattc 1.5b.
I've tried the following:
-SetCPU
-juicedefender (data on only when screen unlocked)
-calibrate battery
-delete batterystats
Still need to try a class 2 card versus the class 4 the phone came with.

UPDATE:
I set my CPU main to "ondemand" at 94% within 30 mins I was at 74%. So I charged for about an hour back to 99% setcpu main screen back to "conservative"..
Today 8/21
- 5am - 99%
- 7am - 90%
- 730am - back on charger
-10am - FULL%
-11am - 95%
-2pm - 85%
- 3pm to 8pm, this is when i got locked up and sent to jail for 5 hours, soooo now I am at 59%
Sooo, in conclusion for mattc NexusLeo Builds vs Darkstone, keep everything the same except your main screen
Max 1113600
Min 245000
Scaling conservative
set on boot
thank you good night
I have found the best combination is Advanced Task Killer and Juice Defender. Don't even need Setcpu with the combination of the 2 above, meaning your build runs as fast as it can, even overclocked I can get easily 1 day out of it. Overnight drain is ~15-20%.
Is it worth it - in terms of speed, fluidity and no screen lag - to set the max value as 1113, instead of the default (998)?
I'm always thinking that we're burning the CPU and draining much more battery.

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,
thanks a lot sander! Using your guide I got my battery drainage on standby from 50-60 mA to 7mA! Really helps, cheers again!

Good find. Shutting off GPS when it was not in use changed my resting MA draw my a large amount. I think that is strange as GPS was not even being used. (seems that this is different between different radio versions).

I use Y5 from the market for shutting off WiFi when I am away from 'known' WiFi points. That really helps with battery drain.
this helped alot now im down to the double digits how do I go down to the single?
What does rooted device mean ? As the application mentioned it in the bracket when i searched it.
Tested on rooted NST with firmware 1.1 and stock kernel.
Simply install SetCPU and set this configuration:
1- go to Main. In scaling select ondemand. Mark set on boot
2- go to advanced. Mark set on boot. Sampling rate=300000, Up Threshold=90, Ignore nice load=0, Powersave bias=300. Apply.
(See attached pictures)
This is the configuration i like, but isn't the one working. You can try new ones.
Underclocking is possible with a free app like CPU tuner (and maybe with other apps, i think), but configuration is a little bit more difficult.
After trhree days of use i can say that really improves battery life.
Enjoy!, and sorry for my bad english.
Has anyone tried this trick?. Works it, really saves battery. Some opinions, please.
I did these settings with SetCPU last night at a full charge, and about 10 minutes later turned off the screen with the battery at 98%, wifi off.
24 hours later, powered on and battery is at 95%.
So I do not see much improvement with battery life during sleep. I'll see how it goes during normal use.
Sent from my NOOK Touch using xda premium
of course you cannot see any difference in deepsleep mode, it changes the cpu behavior while not sleeping (i.e. when you are reading)
by the way, you can also use AnTuTu CPU Master (Free) to do the same for free
Celeborn, I've downloaded Antutu CPU Master. Do you have any recommended setup for this app???
i used the same setup of the [OP] hombretranquilo, it seems to work good
Thanks a lot for the easy settings. I already own SetCPU so it was a piece of cake. Let's see just how effective the app is.
Did anyone tried to underclock it more, to 600 MHz for example?

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.

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.
THIS READINGS FROM MY SGA.
And never ever install the Facebook App if you want to use your phone for more than 3 hours!

Don't get apps that take background processes like what xellar said, facebook, and some other apps like tap tap revenge 4. Anyways thanks for the tips and link to free setcpu
Other people can also share VALID ideas about saving battery.
Will help many users.
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?

This way works without an app.

Didn't help. But deleting batterystats.bin helped. Thanks anyway. :good:
Take a other kernel with better voltage and governor configuration.
Set Display time to 30sec.
Kind regards.
enable "only 2G"
turn off wiifi
turn off bluetooth
black screen wallpaper help?

If you are on CM7 try this... From CyanogenMod setting.
This will help to save battery.

On Amoled-Displays it should help. Inverted Apps, too.
setCPU
i testet the new version of setCPU 3.0.9, deep sleep works perfectly.
If profiles are not used it exits and there is no use of RAM in both versions (But then you do not have the unique feature of auto switching profiles ).
Is there another app with auto-switching?

Actually no idea.
But other simple and best app for controlling CPU is NoFrills.

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
Yes that is nice...

Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:
<snip>
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!

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.
I am using auroraspv3ce final.
With most of time in sleep with wifi, it goes 8-9 hours.
If i use for example twitter facebook, it goes maximum 4-5 hours.
And mostly applications stop or lag so ihave to stop activity. I am using automemory ptimizer in aggressive mode (100 mb free) but still i have this problem.
For example when someonecalls me, 2-3 seconds waiting, i can see the person name. It shows number first.
What applications do you suggetst or what should i do?
I want to do tests memroy and battery tests to see if something is wrong. How?
I have battery problem too is normal not that much. Did you try to reduce clock speed governor? Interactive is good. Try and report.

I dont know how to reduce and what governor is. Can you please tell me about it?
wHEN i open battery in settings, screen is about %25 at least. But my display is always lowets. %15 cell standby, %15 android %15 phone idle and twitter facebook each %4

Yes of course. Go to menu and run application No-frills CPU control. For example select 806 Mhz for Max.clock and 245 Mhz for Min. clock. Governor you can choose Interactive.

I did, it success but what is that for? To reduce battery? It seems now fast, opening apps, closing.
Yes it's for reduce battery. Namely if you don't play games (like me) that clock is perfect for that purpose. Interactive governor is good too mainly if you don't always need screen on aka idle.
You can test others clock for min and max but that governor is excellent.
so eeez
best way to improve battery live is propper calibration
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
it needs root.
best way to calibrate battery is fully charge then unplug restart device plug in charge till 100% and do it again over and over for 3 times then... calibrate battery
fully discharge and charge again till 100 w/o breaks
also update your soft to soon coming v6 of auroraSP
hope i helpd
Battery Drain Wifi
I have done calibrations and changed clock speeds to no avail, Wifi really chews battery on most ROMs. e.g. Fully charged at 8pm and completely dead when i wake up the next morning.
Might simply be a case of new battery, does poor battery affect phone performance?

Yes your battery is dead or almost it's not normal take out so fast
.
You can buy this battery http://www.bigupbattery.com/T-Mobile-HB4F1-Pulse-Battery-p/bupb1694.htm is good but don't except to be perfect. I have that and phone can be 1,5 2 days without charging.
