Good effort posting your findings, I'm sure it will help a lot of people...

I've played with SetCPU for a while trying a few things and found this setup to be the best for me:

I use the undervolted kernel from here.

I use SetCPU as follows:

Main Page

Max: 1113600

Min: 245000

Scaling: Interactive

Set on boot enabled

Profiles

Enable and Notifications checked

Screen off

max: 245000

min: 245000

scaling: interactive

Priority: 100

Charging/Full

max: 111300

min: 245000

scaling: interactive

Priority: 50

Battery < 25%

max: 652000

min: 245000

scaling: interactive

Priority: 50

Advanced tab

Min Sample Rate: 50000

I also have Autokiller installed with moderate settings. Remove all other task killer apps, including Advanced Task Killer...more info why HERE.

I use APNdroid to disable data connection when I'm not using it. But have wifi on all day.
[HD2 Android Q&A, Help & Troubleshooting and Genera] aussiebum:
I can confirm that having the keypad lights ON when starting up Android from WinMo does definitely keep standby at 3-10ma. The other thing you need to do to keep that level of drain is to switch off GPS unless you're using it.

My speculation tells me that there must be something wrong/missing with the gps and keypad light libraries after the dev's modified it to work on the HD2.

Oh yeah and this is on Darkstone's HD2Froyo v2.1
[HD2 Android Q&A, Help & Troubleshooting and Genera] jigners:
nice try but with that "configuration" it would be better if i go back and use my

nokia of 4 years ago. thats no smartphone:o
[HD2 Android Q&A, Help & Troubleshooting and Genera] selivus:
hey bud, i was having the same issue as you. However, i'm pleased to say that doing the following has given me a 3-10ma standby over the course of a week with multiple reboots (just to check if it would work again). I pulled this from the "possible solution for heavy battery drain thread"

"If you start Android don't use WM at all, use auto-boot on 6 sec with Exceller Multiple Build Loader for Android/Ubuntu if you want to use windows, use it but reboot the phone before you start android."

I'm using this with an Energy Rom, 2.10 radio, and warrenb213's t-mobile us optimized build. Works a treat, hope you have the same experience :)

Ps... Doesn't matter if setcpu is enabled or not, I still get 3-10ma on standby, remember if you have autosync enabled you will occasionally get a spike while the phone syncs.

How can you see your power consumption in ma?
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
Its a widget called current widget.

It really really really helps.

I try not to focus on the battery anymore It drives me batty.
[HD2 Android Q&A, Help & Troubleshooting and Genera] selivus:
download "current widget" from the market, once placed on your screen, click on it and set it to update every 1 minute, also it will have an option to write a log file, enable it. Then allow your phone to go into standby for at least a few minutes. You can then view the log file by using astro (which you can get from the market as well). The log file should be on the root of your sd card.
[HD2 Android Q&A, Help & Troubleshooting and Genera] poweroutlet:
Thanks a lot.

Ouch, I'm doing 60ma idle...

I notice I get great battery life when I am in areas with good signal, but right now I am on a boundary of EDGE and 3G coverage so the radio has been going berserk all day switching back and forth between the two. 79% of my battery consumption today has been from the radios, wtf.

Power Tutor is also a nice app if you want really high detail on how much power each application and component in your phone is using. It also produces graphs of this data. Nice app but not to be used on a regular basis as it consumes a fair amount of power/resources itself.

[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
Interesting, people keep saying my phone is slowed down, but thats NEGATIVE. I own an Nexus one as well, My set cpu settings are sufficient, im not sure what programs people run but i NEVER got any slow down on any app, my Hd2 on 600mhz set cpu and no bloatware makes it runs just as good/fast as my nexus one and SADLY to say 600mhz for me runs faster than EVERY persons HTC evo that i have see and used myself which is 1ghz. If anything Evo people complain about slowness, they use my Hd2 with android and 90% of them instantly say "Damn, it moves smooth and fast" so im not sure what people mean by its running SLOW because i set it to 600mhz lol dont let the numbers fool you, my phone runs so smooth you would think i have it set to max cpu.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
Maybe try the 2.12 radio, the latest one. Made a difference in data stability and call quality when i switched.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
if you didnt try the settings yet, why are you trying to slam it? Lets do a quick rundown:

-Tmobile G1 was a SMART phone, i had that it was set on like 333-400mhz by DEFAULT and the phone was still a hit and still enjoyable,

- the Iphone 1 and 3g werent even clocked above 500mhz, still fast, still enjoyable.

- Iphone 3gs, 833mhz processor but only clocked at 600 mhz exact, VERY fast, very enjoyable. and im not sure about the Iphone 4.

-Moto Droid clocked @ 550 Mhz

my phone at 626 mhz is FAR from a dumb phone and i witness ZERO lag using launcher pro. So what exactly are you calling a dumb phone? maybe im a bit confused because your statement makes no sense if you know the best selling smartphones and know the ACTUAL mhz they run at, STILL FAST, still functional, still enjoyable, still SELLING...for a reason my friend.

If a phone processor tells you its 1ghz do you think it runs at 1ghz actual speed? lol set it to the full 1ghz if it makes you feel any better, the MAIN thing i was highlighting though was the speed you set it to when the screen is OFF, that seems to be what bothers people. go to sleep with the phone at 100%, wake up and its either DEAD or down at like 30% thats not cool lol but there are ways to work around it with apps like Set cpu and task killers.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
You can set the speed to any settings, no problem, i was just putting emphasis on the screen off settings and the ROM, Also when i had auto sync on, i didnt get screen freezing, actually i never seen screen freezing so im not sure what causes that. My Auto sync is off for gmail because i use K-9 push mail so that auto checks and i dont need to auto sync contacts so its off and i still get my emails right on time with great battery life lol.

I owned android since day 1 so from various experience, that GMAIL auto sync can drain battery single handedly, they need to work out the kinks there, give K-9 mail a try though if email is the thing you want to come INSTANTLY. Oh and my twitter app auto refreshes too, i just think that stock google gmail sync or the gmail app period...WHACKY! lol IMO
[HD2 Android Q&A, Help & Troubleshooting and Genera] ounkeo:
Brilliant, I'll try that out today! :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
first let me start off by saying you are more than welcome to do anything youd like.

I am making this clear because I dont want anyone to take this the wrong way.

What I do feel is that we really shouldnt promote task killers. Only time they should be used is if you are hunting down a piss poor coded app.

As it stands froyo takes care of the apps handling. If you are having a speed problem It might because by a crap app.

Mvp77 Has put up info on why task killers are unneed and sometimes harmful.
[HD2 Android Q&A, Help & Troubleshooting and Genera] blackwalker:
thx a lot hazard99 for your info!

I'll try some of your settings and i'll let you know,

I set the "airplane" mode in winmo, this also cuts down battery drain, no problems so far within android, apart from the problems i already had (disconnected bluetooth, and disconnected data connection once a while)
[HD2 Android Q&A, Help & Troubleshooting and Genera] robhoeppner:
hi folks,

someone could help me? just tried out some of these hints listed here, also installed current widget and it says it battery drain is about 189mA, got down to 140mA... wtf? is this normal?

in sleep mode it is at 4ma what seems good i think.

got chuckyrom as winmo, turned off everything there.

radio is 2.12.50, android is hyperdroid 1.1.

got autokiller installed but got no clue if it works^^ still got some not necessary processes running. but autokiller looks after free space instead of running proccesses, right? so i just hope it does its job^^

but whats normal battery drain with screen on? i got 3g,wifi,sync,bluetooth,everything turned off.

edit: so i looked in the logfile from current widget right now and the battery drain goes up and down between 100ma and 450ma. in screen off, it goes by about 5ma.
[HD2 Android Q&A, Help & Troubleshooting and Genera] vysus:
Set my phone the way is written in first post.

Left in charge all night while off.

I usually have Exchange Server always on, other mail accounts with every 5 min. check, permanently disabled stock exchange and Gmail checks.

Woke up this morning and started at 7.15, few minutes after battery was 97%.

Now (it's 9.40) battery dropped to 80%: received some mails and SMS and a pair of calls, it seems like it doesn't work for me :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
Are you still using FroyoStone android rom? I get poor battery life on that build no matter which settings i use, i think the battery difference lies heavy in the rom that i used in conjunction with the setcpu settings when screen off. But trying the settings on a different android rom may not work since i know from experience lol
[HD2 Android Q&A, Help & Troubleshooting and Genera] Pitchb3nd:
Hi, first of all, thanks for sharing your setup and personal experience.

What I don't really get is why change any setting on winmo since haret actually stops and wipes out the winmo kernel from ram memory.

Also underclocking, 40% your processor speed obviously helps but is it really worth it?

Just my thoughts, in any case as I said thanks for sharing and trying to help.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
Good post, yeah i seen those forums saying why they are bad, i personally had no problems with task killers but i do see how they can mess things up. I almost forgot Froyo has that built in task killer, I will actually disable task killer and see what I can pick up on.

Battery can suck sometimes in general, as seen with the Htc Evo, Iphone 4 etc, the more advanced these phones get, the more sync features they add and the more speed they add to the 3g or 4g towers will drain more battery, in this case i see phone technology shifting toward the better but battery technology....NOT MOVING AT ALL lol, this is the main problem these days, ha ha ha.
[HD2 Android Q&A, Help & Troubleshooting and Genera] vysus:
So your case is exactly like mine: no matter what build I put on, I constantly have horrible battery drain...
[HD2 Android Q&A, Help & Troubleshooting and Genera] robhoeppner:
so i tried some settings for now and must say autokiller is not as worth as most ppl here say.

only running autokiller seems to kill some processes but current widget still shows me ~200ma - 300ma while normal use. when the phone wakes up current widget shows 5ma and jumps up to over 200ma.

with advanced task killer in auto kill mode on screen off, it stays on 5ma on screen off but when wake up just jumps up to round about 150ma.

dont know if that brings some advantage but seriously know what is better.

and someone else have major issues, that the phone restarts soft resets? just happens since i installed current widget. maybe the combination of setcpu, autokiller or atk, and current widget, produces some issues?
[HD2 Android Q&A, Help & Troubleshooting and Genera] mb:
Might want to switch to GSM mode too, 3G is a drainer.

I will try your settings, but my gut feeling (at least in my experience) is that the drain can be fairly random, rather than SetCPU or anything else being implemented.
[HD2 Android Q&A, Help & Troubleshooting and Genera] 1999TL:
You're not supposed to use a task killer in Froyo that's why.

The drain can be random b/c it depends on where you are and how much signal you have.
[HD2 Android Q&A, Help & Troubleshooting and Genera] robhoeppner:
even not autokiller? thought thats what to use in froyo?!

so uninstalling autokiller and ATK will reduce some draining?
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
Autokiller is not a task killer. It allows you to modify froyos natural ability to kill task when needed. 100-200mah while screen is on is not half bad.

This is not winmo I don't see how you guys can argue with Google's developers and say task killlers work. Once again if you are having spikes while sleep something is wrong

I did the same thing and it says Im running between 500 and 600 ma while screen is on and off. That def has to be bad right?

how do I fix this? Im using bangsters latest build and 2.12 radio
[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
what in the heck are you doing?

post your info setcpu and all.
[HD2 Android Q&A, Help & Troubleshooting and Genera] thenameismax:
while screen is on 768 max 384 min set to interactive

screen off 460 max 384 min set to interactive

wifi off 3g on avctice sync off screen brightness low

what else do you need to know?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Ryan Cordero:
is that -? or while its charging?
[HD2 Android Q&A, Help & Troubleshooting and Genera] thenameismax:
Wow I feel dumb lol it was while it was charging it was that high. But, is that still normal?

Now its running from 100 to 160 mA while the screen is on and off 50 to 60 mA. From what I recall in other peoples posts 50-to 60 is bad
[HD2 Android Q&A, Help & Troubleshooting and Genera] mentalityx:
Dang is that a constant reading for you?? I get occasional spikes to 300mA but that's when this beast wakes up and I update my programs.

i agree with you on the auto killer part but google devs say the exact opposite and so does cyanogen

[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
What i noticed

No problem, i know what you mean. hey EVERYONE, if you try these settings under a different android rom than the one i posted, im pretty SURE you will see a big battery drain because i have tested them all with the same settings, some better than others, if you want to see what im referring to and experiencing, give the rom a try THEN use those setcpu settings and let me know what you think.

For the hell of it, I used titanium to backup everything, switched back to Hyperdroid, used the same setcpu settings and i get worse battery life and in sleep mode im still losing a fair amount of juice.

I switched to Froyostone v2 again since thats what i was mainly using before, great build, but same thing, used the same setcpu settings, got BAD drain with screen off using the same settings.

Switched back to ▐HYBRID▐07.09.2010▐warrenb213 CM6 9/6-V1.5a T-Mo US Optimized▐ Kernel:mitchyprima r10▐ RMNET version http://xdaforums.com/showthread.php?t=775150

entered the same settings again, and get MINIMAL battery drain even with my email sync and twitter refreshing on. did my "Overnight" test AGAIN, battery was on 72% when i slept, woke up TODAY about 9 hours later and the battery was down to 61%, my emails were there, my twitter was updated in the background and all, so my conclusion, whichever kernel or coding they use for their Android rom on that Hybrid must make a HUGE difference because the battery life has been amazing since using this SPECIFIC rom.

Im not sure what it is but give the ROM a quick test run for the hell of it, you will be SURPRISED. :cool:
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
Thanks Hazard, and I use Battery Indicator since its free and it puts the percentage in my status bar, i will give current widget a peep though. I generally try to stay away from widgets since i had a superstition that they add on to battery drain, i have a charger everywhere i go so its worth a shot lol

[HD2 Android Q&A, Help & Troubleshooting and Genera] hazard99:
widgets that constantly poll information pull a lot of data. The current widget does not.

With current widget running I still see sub 10ma drain.

I had the engadget widget running and that caused 40 t0 60 ma drain.

But thats cause it was cycling through the news.

[HD2 Android Q&A, Help & Troubleshooting and Genera] eenbox:
I had a friend who bought a G1 together with me a WHILE BACK :) and anyway - on the end we ended up returning it to Tmobile (he and I, both).

Anyway, he calls Tmobile Customer service and tells them about keyboard, how battery is getting hot and it does not last for very much long. Customer Service Rep from Tmobile tells him to turn-off auto-sync (!), to turn-off 3G and switch it to 2G only (!!), during the charging it is safe that on 50% he takes out the battery and let it cool down and then plug it back to continue charging (!!!) - and he stops the guy that was talking and says: "Don't you think it is the best to shut-off my phone completely because that way I can really preserve the battery - why did I even buy the phone if I am shutting everything down on it!?!?!?!?!?"

I laughed abnormally!!! He ended up returning it the following day.

Point is: Yes, if you want an Android Phone - you gotta be ready to charge your phone every night (overnight) and enjoy all of the bells and whistles :) ... at least that's what I do.
[HD2 Android Q&A, Help & Troubleshooting and Genera] thenameismax:
Well for charging it is. But now that I messed the setting a bit its down to 140 mA with screen on and 50-60 with screen off

is there a post you can direct me to for this trick?

Get 3-10mA on standby

For people who experience 50 - 60 mA on stand by, please try this trick before changing the LED light module trick:

Boot to WinMo and install Exceller Bootloader (Search on this forum). Go to that program and set android auto boot at 3 second. Reboot the phone and let it boot straight to Android. Now check and see of you get 3 - 10 mA on stand by. This works for me every time.

What the trick does is that it doesn't let WinMo fully boot up - base on my understanding - and save some battery power. Good luck....
[HD2 Android Q&A, Help & Troubleshooting and Genera] carhigh:
Im getting the same results, as far as battery consumption in standby and screen on are concerned , with

▐ BUILD▐ 30.08.2010▐ ★shubCRAFT 1.5★CM6 Final★▐ ★Kernel: ElBartoME 2.6.32.9 #1★ ▐

I didnt need this thread to get my results either. This stuff is posted everywhere, and hundreds of times in most of the roms threads.

I highly double these claims!! You sure you played that game all day? With the screen actualy on?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hakeem5:
sure man, its fun to get on Xda and lie about battery stats..... #FAIL results are REAL, and as the original post says, try the specific setup and settings then let me know the results you get, I tried the same Shubcraft rom you had, battery still wasn't as good. People can doubt, thats fine but until you try the exact setups, you wont see the results I posted trying the settings with those other roms because i tried the same and results were not good. Im just on here to share what i have been experiencing for the past 4 days straight, no lies, no frills. Even today, fell asleep with battery on 45% woke up 7 hours later and battery was on 34% so its GREAT on the "screen off" battery management and K9 mail sync on(Main thing that people were looking for).

I play wordfeud all day when at work means, each hour when i get 10-15 mins of a break before clients, i play my turn between 3-5 games then go back to work, my k9 push mail was running, still better results than the other roms i tested.

My screen brightness is at 25%, H and 3G data on, and i still use a task killer to manually close out those hard to kill apps as soon as im done with them.
[HD2 Android Q&A, Help & Troubleshooting and Genera] velayo:
Well, I've been using bangster's rom, with similar settings to yours and I get 0 to 5 mA on standby. On Friday, I unplugged the phone at 9:00 am and made several calls in the morning, installed apps from the market, surfed the net a bit and played some light games (no 3d). In the afternoon I made a call that lasted an hour (around four oclock). Still had around 30% of the battery when I hung up. I used the phone a little more with wifi on and downloaded some walllpapers and other stuff from dropbox. My battery went down to less than 10% after 9:00 pm. That was well over 12 hours worth of battery life, and don't know if I would qualify my use as heavy or moderate, but it was just a regular day of use for me. That battery life was better than winmo, which I had to charge at midday to prevent the phone from dying in the afternoon.

Well, I was using tmous with 2.10.50.26 radio and a 4gb class 4 card. I read that some people were getting better battery life with 2.12.50.02-2 and I just flashed it today. Will be testing battery life with the new radio.

Just wanted to say thank you for sharing the tips. Although, I wouldn't go out to say that I hated winmo on my hd2, I do enjoy my phone better with Android.

Thanks for sharing.
