Froyo roms increase your battery life! try this (UPDATE 08/26/2010)

this may be posted in the wrong section but i would like everyone running froyo to test this out
HERE IS THE LINK TO GET THE LATEST SETCPU
http://forum.xda-developers.com/showthread.php?t=505419
So I have been doing some experiments on ways to save battery life....I think i have made a break through it is not fully tested i would like for some of you to try it out.
with the latest updates to your ROM itself, setcpu, superuser, and the addition of cache cleaner and the incredible AUTOKILLER (a must have) i have been able to run extremely low setcpu sleep profiles without any noticeable loss of performance.
Believe it or not i have my sleep profile down clocked to 19200mhz with out "noticeable" performance loss
i would like for some of you if possible to try these profile out for a while and see how it works out for you
DEFAULT 480min---whatever you want max (mine is 787) ondemand (for performance)
OR DEFAULT 245min---whatever max (for even more battery savings)
SLEEP 192min---480max ondemand (works great even without sleep to wake lag)
it works dont believe me then check out set cpus new feature "time in state"
open setcpu
go over to info
scroll down a little and you will see the times in state your phones cpu runs in the most
you should now see values at the lowest state of 19200
if this works in theory we can benefit from longer battery life
and faster charging
please try these out and report back to the post or PM me...this could be good
Thanks
UPDATE 8/22 EDIT: some users are having success running an even lower default 19min--whatever max (thats even more savings) will be looking into it
try these even lower profiles
DEFAULT 122min--whatever max (screen ON cpu does not drop below 122mhz)
Screen OFF 19min--245max (no lag just ran pandora and cardio trainer at the same time here no lag from sleep to wake either)
or Screen Off 19min--480 max for more performance
REMEMBER not to have conflicting profiles and to have SCREEN OFF at your highest priority
please post here your own findings and results
Thanks again
UPDATE 08/24/2010
after experimenting with other speeds i have finally settled on these speeds for my personal taste on performance and battery savings
MY FINAL SETTINGS...
DEFAULT 19MIN---786 or whatever MAX on demand
SCREEN OFF 19MIN---480 MAX on demand (highest priority) think deeply about why this is the highest
TEMP <40 19MIN---528MAX (screen off overrides this which cools anyway)
BATT <40 19MIN---604MAX
next more into advanced settings....coming soon
UPDATE 08/26/2010
im almost at the holy grail here
try this set up
SCREEN OFF 19--480 (95 priority)
TEMP <40 19--580 (90 priority)
ADVANCED SETTINGS
SAMPLING RATE---100000
UP THRESHOLD---98
ignore nice ---0
power save bias---0
hit apply (if you like it check set at boot)
ALL CPUS ARE NOT CREATED EQUALLY WE ALL KNOW THIS SO DONT EXPECT MY EXACT SETTING TO WORK FOR EVERY SINGLE PHONE
I CAN ONLY OFFER A STARTING POINT BUT ITS UP TO YOU TO TWEAK IT BUT ITS WORK
I HOPE THIS HELPS
things to notice....
in the main screen in setcpu watch the main frequency values bounce up and down...after a few seconds the values seem to stabilize at the lowest frequency of 19
in time of state screen even when screen on most of the time the 19 freq get the most values
i need a few guys to run, test and monitor the values that i just posted ^^^HERE^^^
this may further the battery life once we stabilize the frequency to 19 most of the time while keep the SAME performance which i think i may have did
run some linpacks and quadrants with those setting
i got
5.4 linpack running 787max
431 quad running 787max
then it drops back to 19 and stabilizes
hope this works and please post all your feed back and setting so we can learn this and get it perfect
thanks

I even use 122 and 480 for my screen off profile.. And I don't have any lag at all.

19 is even lower try it

Oh 19200? Wow I wasn't paying attention well enough. I'll try it.

Almost from the beginning of my rooting in May and using SetCPU, I've been using 19.2- 748.8 (on demand) with the screen on (sometimes higher but recently reduced the max to see if it helped with some FC's I was having - still haven't determined if it was the profile or the ROM that fixed my FC's).
I use 19.2-245 for screen off. I'd venture that there's about a one second delay for the caller ID to work once a call rings in, but it's more than bearable and worth it.
I have it go to 19.2-528 when the battery is less than 25%,and 19.2-480 if the temperature is above 49 degrees celcius.

I wonder what it's like when receiving a call. I just set it and I'm not having any lag with just turning it on or anything. I'll test it out with other things. I hope this greatly improves my battery.

shame on you for keeping that secret all to yourself
SHAME

By the way why did you say froyo roms specifically? I'm trying this on tainted tenzo and it's working. I'm usually on a frooy ROM though.

Hi Guys,
Can you please tell me how to get setcpu? I can't find it in the market.
Sent from my Nexus One using XDA App

Search for it on his website, idk what his website is you'll have to search for it. Or download a ROM with it already in it.

im on froyo 30 and was unable to get the 19.2 to show on time in state with screen off profile set to 100 priority at 245/19.2
i was however able to have it start using that frequency by using 710/19.2 as my default setting, then enabling the 245/19.2 profile as screen off.
ive read its not too good to have the cpu jump more than 300mhz per profile though so im not sure how this will work out.

hmm last time i was on sense rom sense fell apart if you clocked lower than 245
epically receiving a phone call
but i only test this method on froyo

I've heard that too. Although I don't know what is bad about it.

i heard that too but all froyo dev have a 245 to 710 stock on their roms
thats why i kinda spilt the two profiles and why 245min--- is experimental
leave your screen off for a while and see if the ime of state shows up
also make sure not to have conflicting profiles running in setcpu

Hmm. Well tainted is vanilla but has some sense elements (like sense dialer) So idk. It seems to work. I'll test out calls.

oh ok tainted is not vanilla
tainted IS sense with sense removed with vanilla remaning hence the word tainted
some sense is still there
i think

Yeah it's got sense contacts and stuff but vanilla messaging. But it has the sense dialer so I think it would also have lag with calls if the sense ones were having lag. And I just tested it and it took a lil while for it to recognize whose number it was but it still gave me plenty of time to answer the call. I'll be testing to see how it improves battery. Thanks for the find

Im also testing setcpu Advanced settings batery life (without performance loss)

What settings are those?

[Q] IS IT POSSIBLE?? pls help

I didnt want to root my phone HTC WILDFIRE because I am a little noob at these things a I thought I would totally destroy my phone.
But I found out that it is not so hard to root it as I thought, so today I succesfully rooted my phone. Than I wanted to overclock my procesor from 528 Mhz to I think 768 by downloading new kernel etc... Everything went good. I succesfully installed(or what, I said I am a little noob) that new kernel and was happy that my Wildfire will be faster.
But now I can see that my phone is lagging more, sometimes it freezes what i couldnt see before when It had original kernel.
HOW IS IT POSSIBLE?
Pls help

Do you have SetCPU installed? Then turn it a bit down, till 690~710 Mhz
Maxing it totally out can make your phone unstable. Think about it like a car, when it has 100 hp's and you tune it to 150 hp's things might break.
From stock 528 to 768 isn't a walk in the park, it's +45%

Yes I have setCPU and when I set my procesor to about 710 Mhz it lags and freezes. When I set it to about 580 it is doing the same. The only one solution of this I think is to reinstal the kernel.
Now I have 2.6.32.21-HCDRJacob-ga91 e 73b- [email protected] 1.
That is the full name of it. And in setcpu info it shows me before the version ( 2.6.32.21-HCDRJacob-ga91 e 73b- [email protected] 1) Linux versio... Maybe thats the problem???
And I have to find some solution as fast as possible because sometimes when somebody calls me I cant answer because of a biiiig lag. And then I cant do anything.
Thx for help

What id the minimum speed set to? I wouldn't go below 160. And my max is 672mhz.
Are you running different profiles or just the main profile in setCPU? Mine used to lag when i had a few profiles running but i have removed them all and only using the main profile and the lag has now gone.

when i went to wildpuzzle i found whatever speed i set my processor through set cpu it froze about 4-5 times a day. after flashing the kernel to remove overclocking it has not frozen in a week. everything really responsive, checking auto detect speeds with set cpu shows max 528mhz min450mhz

I tried many options and at last its OK. firstly I had a big difference between max and min of my procesor at setCPU, so I tried to set it to min about 630 and max about 700.
Now it is OK I dont know how, but I am happy the ****y problem is somehow solved and everytjing now goes very smoothly, thx u all

So what kernel did you flash it to?

[Q] Wakeup timeout too short

So I have the screen timeout set to 1 minute and all is dandy.
Exception - when I take the phone out of standby, 1/2 times it would just show a black screen for two seconds before turning off again. The other 1/2 times it would show the lockscreen for more or less 2 seconds and then it turns off again.
Build is HD2ONE 3.6.0.
Anyone have any idea how to fix this?

You can set a screen-off profile of 422 mhz in SetCPU, also using MDJ's s8 kernel seems to help, and lastly, try to hold the End Call button when waking your phone instead of just pressing it.
In my opinion, the cpu just doesn't seem to scale back up fast enough from the default 245 mhz, and with it set at 422 you can still get 3-6 mA in standby

I'll give it a try, thanks.
MDJ however warns in his kernel page not to set sleep profiles and not to set a minimum of over 245, though.
Also, the last time I used SetCPU I totally destroyed my build by accident.
Well, no risk no glory.

It's no use clocking your CPU any higher than 245mHz in standby, not gonna change a thing.
I suggest to either try a NAND or Gingerbread build, these were the only 2 options that finally completely fixed this issue (for me)

The 422 mhz sleep profile really does work for me. I have my sleep profile set to this on MDJ s8 with BlueTopia and JMWD Ultimate 1.62 and get no SOD with either.
I know it's not recommended, but it's still worth a shot if you want to try things to eliminate SOD.
If you're worried about borking your build, just make a copy of your data.img before applying any changes, then you have a fast easy way to revert, so there's no risk

That's true, and the reason my last build was 'borked' (lol, never heard that word before) was that I pulled the 'max' frequency too high and the damn thing froze, and to make matters worse, I had 'set on boot'.
Now I have a nightly Titanium Backup schedule, I know better, and I can plan ahead so I guess I'll give it a try. It's easier than completely going NAND, which scares the bejesus out of me, or going Gingerbread which doens't have working GPS ATM.
Thanks for all the help guys, you truly rock!

[MAY 01] AmeriCanAndroid AOSP HD2 GB234 CM71|bkup2sdext234 [KERNEL:AmCanAndroid r501]
This ROM works well for me. Maybe you can gv it a try

CPU isn't scaling, not affecting battery life?

Here's an issue I just noticed late last night. My CPU seems to be stuck at max. I've tried different governors, wiped cache/dalvik and reflashed kernel and rom. I also killed all running apps to see if an app was causing it, to no avail.
Here's what really stumps me, my battery life seems fantastic. Not what I'd expect if my CPU is running at 100%. Could there be an issue with detecting CPU speed? As I mentioned before, trying different governors doesn't help with scaling but I notice when I select "powersave" my CPU jumps from max to the minimum value and stays there, still not scaling.
Before someone mentions I did search before posting. Went through the threads, tried the suggestions within and still have the problem. Hence why I'm posting here now.
Am I overlooking something? Any help will be appreciated, thanks!
Edit: My current rom and kernel are in my sig.

so are you monitoring this via setcpu on Decks?

Yes I am, is there a known issue?

My understanding is that having both setcpu and the native CPU performance running will result in some conflict. that is probably the problem, but I don't know how to monitor the scaling with the native performance. so i see what you are trying to do.
I never run setcpu on CM7 or Decks because it is built in, but if the battery life is alright, it would appear the built in takes precedence.

Is there a good way to monitor the CPU without setCPU? Thanks

check out "system panel"
edit: or android system info app > system tab > cpu. gives you a break down of time (%) spent at each frequency.

Thanks, I like that app a lot.
Unfortunately even after deleting setCPU I'm still seeing 100% CPU usage. According to system panel the System is using 80%.
Edit: I am underclocked to 499MHz, and that's where she's pegged. Still oddly enough I'm getting the best battery life I've seen in weeks.

My CPU doesn't scale correctly either. Its either running at MAX, Deep Sleep, or 245mhz. Never does it use the in between frequencies no matter what govenor I use(I have tried them all). I use CPU Spy to check scaling and No Frills CPU to change the governor both are from the market.

so if you do this:
or android system info app > system tab > cpu. gives you a break down of time (%) spent at each frequency
what is the frequency while it is sleeping?
1. you may need to overclock just a bit
2. you may want to reflash rom without wiping the data and see if that helps
3. every phone is slightly different, so yours may need more time to process the commands at 499, especially if you are undervolted as well. which is why you getting pegged.

Thanks, says the time spent at 499 MHz is 92.51%. I don't think underclocking is the issue. If I overclock to 1113MHz it will peg there as well. Seems to only go 100% when screen is on however according to the system panel app. I'll try your suggestion in (#2) and report back.

Tried reflashing the rom without wiping. Still have the same issue. So odd. I'll try a different kernel just to see if that helps, but I'd hate to part with my 3.3.7 LEE kernel.
Last thing I can think of is doing a full wipe, but I'd like to avoid that if I can.

Definitely experiencing the problem with other kernels. I'm out of ideas.

Did you try tiamat 4.1.0? I'm using it now and the battery life is right there with 3.3.7.
Sent from my PC36100 using XDA App

Did you restore any apps with titanium backup by chance?
Sent from my PC36100 using XDA App

By the way, I appreciate all your help alaman68.
Tiamat 4.1.0 was the other kernel I tried. No luck. Also I've never used titanium backup to restore apps. I'm stumped as to why my CPU won't scale anymore. The Android System seems to be using as much as I allow it.

Trying, you could try a sense rom for a day and check the scaling for a benchmark.
Is there anything else you are running? Undervolting, v6... Anything else?

Not undervolting as my phone never liked it. Nor running V6 or any other scripts either. I'll try flashing a sense rom, see if I have the same problem there. Or else, think doing a full wipe and reflash everything would help?

if all else fails, a clean flash won't hurt. Even get a new download. Gotta ask, did everything properly? you using amon_ra recovery? did you download any new apps when that started happening?

I may just have to. I suppose there's always a chance I made a mistake somewhere, but I've been at this rooting/flashing thing for a long while. Thing is, everything was fine up until I noticed it last night.
I'll do a clean install. I can always nand restore if it doesn't work. (Save me the time to set up everything.)
I'll report back

Did a clean install and guess what, my CPU is scaling again! There must have been a conflict somewhere. Thanks again alaman68 for all your help and suggestions. Sometimes these phones get gremlins I tell ya.

Wifi issues on all cooked roms? Overclocking side question

I have a HD2 with an older version of android cooked on. Android version 2.3.7 Kernel version 2.6.32.15_tytung_r12.4-heebf2c Mod version is CyanogenMod-7.1.0 Desire (Typhoon_v3.7.0 Magldr) I think my radio is 2.15.50.14
I really need the wifi calling feature on my phone to work. Do all the roms have this problem on our phones? Would it be easier for me to just install a new rom? Every time I turn on wifi, the phone freezes completely. I read through the post regarding this issue, but there was no specific information given about how to overclock the phone. I downloaded nofrills cpu control and have tried random combinations, but was wondering the ideal oc speed?

I never used Tytung's GB rom but wifi generally works very well. I used it all the time with Typhoon GB, Tytung's ICS and JB.
For overclocking Install Setcpu from the Play Store.

Can you give me an estimated range I should set my cpu to? I can't find the thread, but somewhere along the line I read something about how you should over clock your processor in multiples of something. I'm not describing it well, but maybe it had something to do with a mhz speed and then a frequency or another unit of measurement for power. Like volts. I have no idea, what I'm trying to say is that I read there is some sort of calculation you need to figure out in order to properly adjust your cpu settings.

I think that all better apps for this already take care of much of what you are looking for. I know SetCPU does - in fact it has profiles for numerous phones, including the HD2. The one disadvantage that I tend to forget is that it isn't free. If you look at the app's description on Google Play you will get a lot of ideas. Likewise, the developer's web site also has some good info.
Briefly, I do not set any profile's low frequency below 245 MHz (potential SODs). The high-end you can experiment - if the HD2 locks up reboot and set it lower.
I have a default profile and change it to faster MHz if plugged in (I don't care about using more power when plugged in) or lower frequencies for sleep or overheating and such. If you do get SetCPU you can plug in the attached profiles (don't forget to unzip it first!) and see if you like any of them. They can all be changed or deleted, of course.
