DevilMind007: You're obviously using SetCPU (ref@screenshot), and you're running an old version as well. Get the new one for I/O the functionality.

In / Out scheduler, pretty much says its main purpose. Google if you need more information.
[Galaxy Ace S5830 General] umasiva:
this is a noob question. I set the CPU max and min using ROM toolbox. How do i set the other details?
[Galaxy Ace S5830 General] lukip005:
I must say great TUT !
[Galaxy Ace S5830 General] SuperAce609:
Why are you using rom toolbox? I can't give you any details because I don't use that. Please follow the guide so I can help you if you ever have problems and ill know what I'm telling you.
[Galaxy Ace S5830 General] Chin2:
battery performance is very strange... battery was full..i checked in phone status... within few mints it drops to 90% without any usage...

it happens many times... i did battery calibration earlier... still facing this issue..

Using Democracy V2 ROM... i know stock based ROMs have more battery backup...

bt how to to fix this :(
[Galaxy Ace S5830 General] SuperAce609:
I don't know what in the world is wrong with democracy. I was using that rom and no matter what I did, the battery dropped an insane amount over such little time. I switched back to The Myth 2 and I've been having some amazing battery life ever since.

Uninstall that rom.

Tried updating kernel?

Sent from my GT-S5830
[Galaxy Ace S5830 General] SuperAce609:
I don't mess with kernels. I have very bad experience with them. Whether my phone suffers with performance or the battery gets worse. I use the ones the roms I install come with.
[Galaxy Ace S5830 General] pmcunha89:
I think the best way to save battery life is charging it at full, and then restart mobile in CWM, and calibrate batery stats..
[Galaxy Ace S5830 General] SuperAce609:
You lose battery while restarting. And why have all the trouble of booting to CWM when you can do the same thing with an app with just a 3 taps away.

1. Open app drawer

2. Tap on app

3. Tap calibrate battery.

Now you tell me, which one is better?
[Galaxy Ace S5830 General] WYPIERDAALAAC:
when you have a call and you set profile to max 480 you can have lags (for example only sound and black screen) i have it

This is the amount of RAM allocated to one application.

If larger the applications run faster but you can have less apps running in the background. (because each uses more RAM)

If you set HS to smaller apps go slower but enough space for more applications in the background - better stability
[Galaxy Ace S5830 General] SuperAce609:
Errmm.. I'm still confused. Haha. But regarding the profiles, I made this guide so you can have a basic idea of what you can do. You don't need to necesarily put the ones I've posted. You can play around with the settings to see which ones suit you best.
[Galaxy Ace S5830 General] QNBT:
Good job bro :D
[Galaxy Ace S5830 General] DevilMind007:
you have not mentions what I/O you choose for SetCPU??

sio or noop or some other???
[Galaxy Ace S5830 General] SuperAce609:
I dont change that.
[Galaxy Ace S5830 General] DevilMind007:
that is what i'm asking

which I/O is default??
[Galaxy Ace S5830 General] QNBT:
For general use, sio > noop
[Galaxy Ace S5830 General] Falcon1:
I recommend

I know that there are many ways of saving battery life. but there is one that has to do with using black or dark wallpapers and widgets. the screen color does not make use of light and your device will live more without electric cord. I tested many times and it worked:good:
[Galaxy Ace S5830 General] DevilMind007:
yup he is right. i do the same. :highfive:

-plain Dark wallpaper & theme

-every app on dark theme if option.

-screen at Max Dim (only 100% bright when i'm outside in Sun)

-Governor under speed i have Max 540-Min 122, SmartAssV2 + I/O noop is best battery saver

-no widgets run, only 2 screen at Home.

- GO Task Manager is Great, before screen lock i always Advnace Kill apps then lock it.
[Galaxy Ace S5830 General] SuperAce609:
Yeah but those are just little tweaks that will take out the whole point in customizing Android. I'd rather have a lively looking wallpaper than a plain dark looking one all the time.
[Galaxy Ace S5830 General] antartsync:
yeii.. thanks mate. i have saving battery with this method and dark wallpaper :good:
[Galaxy Ace S5830 General] guto-camargos:

I installed setcpu today and set two profiles. One is screen on with 245-806Mhz and other is screen off with 122-320Mhz. When I play songs and screen gets off then I get some glitches and same is when I turn on screen. Also with this phone is not going into deep sleep. Is it because of the cpu transition?
[Galaxy Ace S5830 General] SuperAce609:
Phone doesn't go to deep sleep when you're listening to music. But if you are, set the max frequency to 480 so the sound won't lag. I don't use my phone for music so it doesn't apply to me.

Phone goes to deep sleep as soon as it's not in use. Did you download CPU spy? What rom are you using?
[Galaxy Ace S5830 General] ankur3290:
I understand in music it won't go into deep sleep. But without music also its not going. In cpu spy its showing 122 where as it used to show more in deep sleep without setcpu app. I am attaching the cpu spy screenshot. I am using CM10 Jellaxy.
[Galaxy Ace S5830 General] livewirerules:
i had huge battery problems after updating to a custom rom.. worth giving this a shot... :)
[Galaxy Ace S5830 General] SuperAce609:
Well sir, it seems to me like it's a rom issue. As you can see from my screen shots, everything is working fine. It's also always worked no matter what rom I've used.
[Galaxy Ace S5830 General] ankur3290:
I have the latest CM10 Jellaxy. BTW which version of setcpu are you using?

Thanks.
[Galaxy Ace S5830 General] SuperAce609:
Version 2.2.4. The new one doesn't show active notifications which interrupts Set CPU and lets it get killed by the ram management. Which results in the set CPU settings not staying on and the application asking for root every time it needs to be restarted.
[Galaxy Ace S5830 General] ankur3290:
With this version its going into deep sleep.

Thanks.
[Galaxy Ace S5830 General] SuperAce609:
Oh really? Thanks for the info. I'll add it to the first post.
[Galaxy Ace S5830 General] ankur3290:
Also there are no glitches in music with screen off and on. :)
[Galaxy Ace S5830 General] SuperAce609:
So the new app is faulty.

I knew I didn't like it.
[Galaxy Ace S5830 General] ankur3290:

Hi! I totally agree with the battery calibration proccess. On the other hand i wouldn't recommend the Set CPU option cause i had tried it in the past and had some problems. Although it's good for battery life in can be frustrating when for example you get a phone call and the device is stuck cause the proccessor was working low while the screen was off (i have lost many calls like that since i had to remove the battery to get the device working again :P
[Galaxy Ace S5830 General] SuperAce609:
What are you talking about dude? Just set a in call profile to the normal one you daily use. Like 245-800 or something and it'll work perfectly.

What I posted here are just things to guide yourself by. You don't have to try these exact settings. Try the ones that work for you.
[Galaxy Ace S5830 General] stevenkyk:
But isn't setting powersave the same as setting the min and max at the same clock speed? Music players have to be excluded from this profile as it will lag if using powersave. A seperate profile that has a higher priority will solve the problem thou.
[Galaxy Ace S5830 General] SuperAce609:
Powersave will FORCE the phone to run at the minimum frequency at all times. It is definitely not the same.

Why would you set a different profile if you're gonna listen to music when a normal screen-off would apply to everything you need?
[Galaxy Ace S5830 General] Venomous Viper 119:
A tip to all :

The time you see in About phone ---» Battery, isn't the indication of how long your battery will last. But it is the indication of how much time has your phone lasted on the battery, after you last unplugged your charger. For example, if you have unplugged your charger at 9 in the morning, check the time in, about phone --» battery at 9 in the night. It should show 12 hours !
[Galaxy Ace S5830 General] SuperAce609:
A tip? Who doesn't know that? Are you new?
[Galaxy Ace S5830 General] Venomous Viper 119:
Many people were confused. They have posted the screenies & quoted that their " Battery goes crazy after charging. Just 4m 32secs on battery ! " & such posts I saw. So I thought to help avoid the confusion & by the way, I'm not new here, I've been here more than the time for which the world's oldest wine was stored :D
[Galaxy Ace S5830 General] SuperAce609:
Oh lmao alright. And yeah, the battery meter reachea 100 pretty quick and as soon as you disconnect it, it takes it as a full charge even when its not. That's why I love that 100% stock rom notification :D
[Galaxy Ace S5830 General] Venomous Viper 119:
I prefer charging with phone off & I charge it for 3hrs. after a day full of usage & I'm never mislead by those notifications. Android as a whole is great but it's equally well confused within itself. You know, sometimes I feel, our java phones are far better for what they offer.

my galaxy ace flash to CM10, clock lower proc speed still doesn't save much when i on 3G why the battery life is so bad?

even if i off 3G, GPS, bluetooth, and lower display brightness there is no termendous saving on battery life.

i will finish withn 12 hr if i on the phone .
[Galaxy Ace S5830 General] SuperAce609:
CM10 has horrible battery life which is why everyone complains about it. And if you read the whole first post, you'd know what happens when you turn 3G on. If you have over a year with your battery, it's about time to replace it. It'll stop holding charge as much as it used to before.

An even better way is to use JuiceDefender ultimate. It undervolts your phone when idle, and can so turn off wifi when you are away from your home. It is the best battery saver ever!

[Galaxy Ace S5830 General] Bakuron:
Thanks very much for creating this thread, very interesting.

I'm interested in seeing if SetCPU will work on my stock/rooted 2.3.3 (I am phobic of custom Roms due to my internet connection being so pathetic as to virtually guarantee bricking my phone when flashing).

I'm currently getting about 14 hours average life out of my beloved Ace, with approx. 8 hours 2g browsing every day. The biggest batt drain (50-65%) is from my cell radio struggling with the very poor service area I'm in. I'm not expecting miracles but if I could somehow 'underclock' without flashing a new rom and get another couple of hours usage out of my phone I'd be incredibly happy.

In fact this is the primary reason I rooted my phone in the first place. EDIT2: I've installed it on the phone, no problems, so now it's about experimenting. Any advice would be appreciated and I'm likely to be writing up a beginners guide to smartphone battery use so results would be included.

Cheers

Thanks, going to try uot kitchen, but if i cant work it, be expecting a message!.. :)
[Galaxy Ace S5830 General] Bakuron:
Ok conservative mode 480mhz max, tiny lag on keypad animation and on browser functions when running GTalk and Opera. Will monitor battery performance over next few hours.
[Galaxy Ace S5830 General] Bakuron:
With those settings applied to 'screen off' do you have any problems receiving calls or notifications?

---------- Post added 28th January 2012 at 12:07 AM ---------- Previous post was 27th January 2012 at 11:39 PM ----------

OK so this was my first experiment after applying the 'Conservative' Governor (Schwarzenegger?) I started it midway through a day of normal usage at the 30% mark.

-Went from 30% to 4% in just over 3 and a half hours (screen constantly on, almost constant browsing/chatting).

-Now at 4% (as you know the battery clings on for dear life at this stage) with totally dimmed backlight lasted for exactly 1 hour.

-Whilst at 4% only GTalk running (obv a few in background) still with 2G and background data enabled + Location via network.

That's a total of 4.5 hours on 30% battery but with almost constant use, background data and internet. That would mean a full battery cycle could be made to last 15 hours of constant usage (underclocking half the processor power) -

a good 55-65% better than I was averaging previously.

And as a reminder that's with stock 2.3.3 in a very bad signal area.
[Galaxy Ace S5830 General] SuperAce609:
Juice Defender sucks. I've had it. All it does is shut off different radios during specific times leaving the battery exactly the way it is.

This underclocking method increases your standby time so you have more usage time while using it. Unless you underclock your main profile too, then that'll increase your battery life in general.
[Galaxy Ace S5830 General] SuperAce609:
Yeah, at 480 lags a little so I set it to 787. Drains a little more juice but less lag.

As for the calling profile, since I have my min cpu set to 122 during screen off, the phone vibrates quite a bit before it displays the call and I'm able to answer it. That's not a problem for me since I still get to answer the call. But if you want to avoid that, set min cpu to 245.
[Galaxy Ace S5830 General] Bakuron:
Right, but that's on the CM kernel right?

I have the free version of JuiceDefender still, which is OK just for switching off data and background. I somehow prefer the idea of them being switched off rather than struggling along with zero processor power. But again, that's all for us masochists who are insisting on sticking with our stock roms. :D
[Galaxy Ace S5830 General] SuperAce609:
Lmfao you can still do all this with the stock rom. You just need root. I personally need an active data connection always since I use data texting and my widgets depend on it too which is why I only use Edge and not 3G for more battery saving ;D

full 40 min using 3g and quarter brightness level and only dropped!! 18% , before my amaziness :P i would have used 40 min using 3g my battery percent would be at like 17% :o lol
[Galaxy Ace S5830 General] SuperAce609:
That sounds about right. But I'm still interested in your fix. Is it some Juice Defender kind of thing?
[Galaxy Ace S5830 General] Bakuron:
Battery performance not nearly as good as hoped for today. My experiment yesterday was all about underclocking whilst screen was on and I was using it, but today I'm guessing (could be wrong) that SetCpu was using battery whilst in 'screen off' mode to enforce the 'screen off' setting of 122/245.

What usually happens when I use my phone for a few minutes after periods of inactivity is that the battery reading suddenly drops sharply (to a more realistic reading of remaining battery life) - No exception today. So right now it looks like underclocking whilst in standby hasn't achieved anything - but I could be wrong.

When looking at the 'info' tab on SetCpu it says it's spent:

- 0% of the time at 122mhz

- 50% at 245

- 10% at 320

- 20% at 480

- 20% at 800

The first and last figures seem somewhat disproportionate considering it should only have been on 800 for approx. 1 hour out of 10.5 so far today with the 'incall' profile. And surely when in standby it would be operating at 122 > 245mhz most of the time, or at least some of the time. What's pushing it?
[Galaxy Ace S5830 General] SuperAce609:
Hm. Really? My readings say otherwise. I've rarely used my phone today so I guess that doesn't really count. On a regular basis, it would've been about 15-20% by now. But also it depends on what I use the phone for. Mostly just Twitter and some facebook. Haven't experimented with 3G on instead of Edge. Taking up on that experiment tomorrow.

Are you have input some modifications in build.prop (the power collapse settings and sleep mode?) When yes it's normal, when you turn off you screen you phone goes into deep sleep mode - in this mode all process are stopped - that means SetCPU doesn't make statics.

[Galaxy Ace S5830 General] tomy2590:
Good update! :) but there's something I want to share here. In my experience, I used 122 min and 320 max with powersave as screen off profile. When someone calls me, my phone lags like hell (no, not like hell, but laggy) but still it rings. weird. It takes me to wait for at least 8 seconds before I can see who's calling. I changed the profile from powersave to smartass, and as far as i can see, there's some improvement :)
[Galaxy Ace S5830 General] Bakuron:
Thx for all replies but after reboot its working fine. Going into 120 almost all the time that its on standby. As such I wonder if its even necessary to put max as low as 240 on standby profile.

Just experimented with that now. Not much lag for me in that respect. Only that the phone continues to ring for a few seconds AFTER i tell it to hang up. Edit: I use 'conservative' with 120/240.
[Galaxy Ace S5830 General] SuperAce609:
Powersave runs at the MIN cpu ALL TIMES. Meaning it'll be running at 122 even if you have max at 320. And yeah, that little lag happens to me too. Its normal if you set it to that low frequency.

But hey, extreme battery saving in exchange for some call lag. Lol, I really don't mind.
