Download the app called "Battery Widget" from play store, it can alert you when battery is truly full. And why would you need deep sleep (only useful for saving battery) while charging anyway?

EDIT: I see there are multiple apps called Battery Widget, but this is the one I mean: https://play.google.com/store/apps/...xLDEsImNvbS5lbHZpc29uLmJhdHRlcnl3aWRnZXQiXQ..
[Galaxy Ace S5830 General] chrcol:
How do you get to see which apps using battery power like in your first screenshot? mine only shows idle, sleep, display and voice usage, but no apps.

I have trialled using airplan mode overnight and found my drain after many days of usage to be consistently higher. It does slow down its drain during the night but I can only assume tasker does more work during the day checking the time etc. to know when to start as the overall drain is higher. Also I believe tasker and setcpu to conflict as when I changed tasker to foreground onitoring the wakelock issue goes away, so I get wakelocks when setcpu is on and tasker is in background, if one or the other applies but not both at same time is no wakelocks. However tasker in foreground slows down the phone noticebly and there is more drain. So I am back to no airplane mdoe, tasker background (for my profiles) and setcpu with wakelocks.

The main issue now is during voice calls I get huge drain. A 10 minute call drains about 5%, an hour call drains about 30% in one go. These calls usually with the screen off and speakerphone off. Something in android is really inefficient on battery power, because if I compare eg. to my nokia that has only a 800mah battery but it lasts way longer and things like phone calls dont cause huge chunks to drop out of the battery. So I have dropped my in call profile clock speeds to see if that been set too high is a cause. Since most of you guys use 3G etc. all day I might for a day leave wifi etc. on and just see how my battery lasts as that I have never tested.
[Galaxy Ace S5830 General] Bakuron:
They should start to appear once you have rooted.
[Galaxy Ace S5830 General] chrcol:
I been rooted for months and they have never shown.
[Galaxy Ace S5830 General] SuperAce609:
Weird, what rom are you using? It used to be like that for me in CM7. Meaning it did show the apps that consumed the battery.

Also, I didn't quite understand those 2 paragraphs in which you stated your problem. Would you mind being a little clearer?
[Galaxy Ace S5830 General] chrcol:
still using stock 2.3.3.
[Galaxy Ace S5830 General] Bakuron:
If I remember rightly you tend not to charge your phone for a couple of days at a time. As such you have long periods of inactivity. What I have found is that the battery monitor doesn't correctly read battery usage during periods of inactivity, and when you use the phone for the first time in a few hours it exaggerates how much battery power is consumed when reaching the more accurate battery reading.

What I'm saying is that your phone isnt draining 30% in a phone call, but that it's drained 20% more than it's saying in the time it's been in sleep. You can see this more clearly when you use the phone consistently for hours on end, where there are no major drops just steady depletion.

Thing is that the Ace is designed to be charged every day. Like 90% of ALL smartphones. They never advertise that fact of course, but it's much more a hardware efficiency issue than software. As the next gen of phones are using more specially designed tech without having huge 3000mah batteries like the RAZR maxx. Only 1700 in the S3. 2000 in the HTC One X.
[Galaxy Ace S5830 General] 4r4n0r:
setcpu not needed with samrtassv2

I use the same but Max 800 (when the screen is on you have max performance you can have, when off the same as you - thanks to samrtassV2)
[Galaxy Ace S5830 General] chrcol:
That may make some sense.

eg. I can have an idle period of 2 days, make a 5 min call and suddenly the battery drops like 10% for that 5 minute call which seems crazy. Likewise taking a photo with the camera can drain 20% in one go but usually after a period of idleness.

Today I have started an experiment, got 3G on, screen timeout 30 minutes and ewill turn it back on if times out. Also trying to use it for photos etc. to emulate heavy use. Will also do many phone calls as well and see how the battery drain graph looks. So far used 10% in 2 hours.

---------- Post added at 07:53 AM ---------- Previous post was at 07:51 AM ----------

which rom you guys using? As I understand it is no official CM for ace?
[Galaxy Ace S5830 General] SuperAce609:
I know the camera takes a huge drain just by even having it on. The battery meter on the Ace is messed up. Now I understand where you're coming from. If your phone stays idle for 2 days, the battery meter will stay the same since its bugged. Then as soon as you do something on your phone, it'll drop down to the "amount left" of battery that it think it has. Put it in quotation marks because the meter is never right.

Which makes me wonder, will there ever be a fix for this?
[Galaxy Ace S5830 General] chrcol:
on todays expirement using the phone heavily I now got an app showing 2% and wifi 3%.
[Galaxy Ace S5830 General] SuperAce609:
Yeah, the detailed app battery consumption only appear on CM7.
[Galaxy Ace S5830 General] Bakuron:
Yes. Been browsing on mine today for 5 hours. Opera 10% usage. Apps dont use much. Ads in apps do.
[Galaxy Ace S5830 General] chrcol:
I think at around the 10 hours mark yesterday with keeping screen on all day 3G on and using it for things I wouldnt normally do it was down to about 25%. So I can see now why people arent happy when using it heavily, thats not a lot of use. But with that said it didnt jump down in huge chunks it was just a fast gradual drain.
[Galaxy Ace S5830 General] chrcol:
After upgrading to 2.3.6 from 2.3.3 battery life seems a large jump up, in 10 hours its used 4% battery and the awake periods on the battery graph are tiny so the phone seems to go back to sleep much quicker.
[Galaxy Ace S5830 General] Bakuron:
Did you do that through Kies?

Edit- Actually you have to stop thinking about it as a phone and start thinking about it as a computer. 10 hours is great by any laptop standard.
[Galaxy Ace S5830 General] chrcol:
but it is a phone.

95% of my use on it is as a phone.

I understand your view if I was using it on the net etc. all the time but I dont.
[Galaxy Ace S5830 General] SuperAce609:
Well, if you're gonna use it just for calls, make sure you do it on 2G which makes the battery last longer. You didn't read the phone spec sheet, did you?
[Galaxy Ace S5830 General] chrcol:
?

Obviously I do turn 3G off unless I need it.
[Galaxy Ace S5830 General] SuperAce609:
Yeah, if you STAY on 2G, you'll get a better battery life than switching between 3G/2G. But oh well. Lol your phone.
[Galaxy Ace S5830 General] Bakuron:
It's a smartphone. Which is marketspeak for a computer with phone capabilities. The clue is in the fact that it has a CPU, GPU, RAM and an OS, all things a phone has no real need for in that form.
[Galaxy Ace S5830 General] Adenilato:
I did everything you said, and 27% battery gone away in 5 minutes
[Galaxy Ace S5830 General] SuperAce609:
That's absurd. You must have had 3G on and using it. The Ace's battery goes down incredibly fast when the phone is in constant use. Either way, that's still a lot. You need some major calibration.
[Galaxy Ace S5830 General] Adenilato:
Sorry...I didn't mentioned that I just removed the charger and, without any use, good bye battery. Now is stable at 73% for 7 hours and 25 minutes (without use too). And everything is off (3g, mobile data, wifi, etc...)

When I was on step 7, the battery was good.

Sorry for my english...
[Galaxy Ace S5830 General] brix99:
based on my experience stock based ROMs outperforms CM based ROMs in terms of battery performance.
[Galaxy Ace S5830 General] SuperAce609:
Then I don't know what to tell you. My own battery is starting to have issues. It cant seem to hold charge no matter what rom I'm using. Normally on Stocklive V6, I get around 10-12hrs on 3G but now with 3G on I can't even get past 2 hrs.

Just did a complete clean flash of the rom and calibrating battery to see if its fixeable. If its not, my battery's the problem.
[Galaxy Ace S5830 General] SuperAce609:
Lol yeah. That's a definite. I don't know why though. Always wondered that.
[Galaxy Ace S5830 General] chrcol:
not on my phone now with CM and the fire kernel.

stock gave me 5 maybe 6 days at a big push when underclocking using setcpu.

I just had a 10+ day charge on CM with smartassv2 no underclocking and the fire kernel.

currently on 73% with 3 days 16 hours since charge.
[Galaxy Ace S5830 General] SuperAce609:
Geez dude, wtf do you use your phone for? Just to check the time? You're definitely not using it as a smartphone.
[Galaxy Ace S5830 General] oscake:
Brightness, 3G and WIFI are main factors
[Galaxy Ace S5830 General] SuperAce609:
Yeah but even so. Phone has to be on like 95% stand by for that much saving. And specially the Ace's battery.
[Galaxy Ace S5830 General] pyronia:
Well, it work for me...i use 5 different profile on setcpu...

In call

Battery 50%

[Galaxy Ace S5830 General] SuperAce609:
Oh really? Cool. I'll add the in call as a new profile. Thanks a lot for the heads up!
[Galaxy Ace S5830 General] SuperAce609:
Hmm.. I don't think having so many profiles is such a good idea. But oh well. Whatever works for you is fine. If you run into some performance issues, I think you'll have to fix that up. Since SetCPU is an app after all, there's a possibility it might crash or run into some problems now and then. And since it handles your CPU, well.... you can already know.
[Galaxy Ace S5830 General] arip30:
Are you using Galaxy Ace S5830? Which ROM?

Cause I've try that setting last month.. Hiusss... Lag gile..menyesall...
[Galaxy Ace S5830 General] pyronia:
Haha...wa pakai ace la, stock xwks2 2.3.5 rom...kernel cf-root b84...

System rfs convert to ext4 with 2nd partitions use link2sd...remove bloatware..

Working great! If u use custom rom such cm7, better clock down your cpu fot better battery..until now cm7 still have battery issue.

If u use stock, make sure if u delete bloatware, DONT delete syncmldm.apk and .odex (it will drain batt when remove)
[Galaxy Ace S5830 General] dragonnn:

I wonder how u manage to get cpu 600mhz??? What kernel do u use?

The profile use only smartassV2 and 2 conservative governor, why not choose powersave for screen off?
[Galaxy Ace S5830 General] pyronia:
Currenthly using the setting below...
[Galaxy Ace S5830 General] dragonnn:
I am using zImage-Mod v1.0 http://xdaforums.com/showthread.php?t=1292200 :). I am using to screen off conservative because powersave give me an unlock lag (on it you CPU is running always on the min frequency). And the battery <15% should by too smartassV2, forget to change it. The main profile is too smartassV2 and max is 800Mhz, min at 240Mhz.

Herpderp Adreno + Tegra.
[Galaxy Ace S5830 General] SuperAce609:
Its not only for CM. It should work on any rom you're using. Its just messing with the CPU settings, there shouldn't be any rom limitations. Except for stock though, for that you NEED root.
[Galaxy Ace S5830 General] noob 911:
prblem...

so on the profile tab i only will have 1 profile...? (by following the 1st post...?) please explain to me...:confused::confused::confused:
[Galaxy Ace S5830 General] SuperAce609:
Yeah. You'll only have one profile. But if you want more, you can keep doing the same thing and putting them in different situations, not just screen off. I personally only have 3 profiles. Main, screen off and charging.
[Galaxy Ace S5830 General] dragonnn:
I was talking about the zImage-Mod kernel:D.
[Galaxy Ace S5830 General] SuperAce609:
Weird, what do kernels have to do with that? Are there some that won't let you mess with the cpu settings?
[Galaxy Ace S5830 General] dragonnn:
A many, stock kernel only have a few steps of frequency 800Mhz, 480Mhz, 320Mhz, 245Mhz and 120Mhz. On zImage-Mod you have 800Mhz, 735Mhz, 670Mhz, 600Mhz and many more. You can batter adjust your settings in SetCPU like my, when my battery goes down, my processor slows to save battery but I didn't get lags in the UI, on stock kernels when you set the only available lower then 800Mhz frequency - means 480Mhz you will get many lags in the UI.
[Galaxy Ace S5830 General] pyronia:
What is your main profile?

A smartphone can be used for multiple things.

It seems everyone keeps asking me this question in different threads.

I use it as a phone with occasional internet use, and I gain from easier sms messaging etc. as well due to the keyboard layout and auto complete on words.

The phone is used, but I dont sit there playing games on it all day and using it for the net all day.

I know plenty of people with smartphones as well and they use similiar to me, dont assume one has to be using it like a computer to have a smartphone.

i've tried to underclock my ace for two weeks, it's laggy if i set the cpu at 480, so i set my cpu at 614 and everything is fine until now.

sorry for my bad english :)

Super Battery!!

My 1st post on this site!

using Apocalypse ROM for my SGA, along with a battery script tweak meant for the Galaxy mini & Firekernel OC

As of now, my battery has clocked 2days 8h and 50 min with 23% remaining.

Set CPU is a saviour! From stock rom of using 18-20 hours on battery to 2 days regularly now with frequent texting, occasional calls, music and WIFI.

Airplane mode when I'm asleep.

Smartass V2 governer for all

Normal usage (Completely lag free)

Max 614

Min 122

Profiles in set cpu

Charging, In call & Games - Max 787, Min 245

Screen Off - Max 245, Min 122.

I use advanced task killer pro to frequently kill unwanted apps but manually do it.

I'm Happy with my SGA!!:):)
[Galaxy Ace S5830 General] coolfox14:
is it gonna be laggy if Max CPU be in 480 MHz insted of 800Mhz???
[Galaxy Ace S5830 General] SuperAce609:
No it won't. It will be if you use heavy apps. But over all just for browsing, not at all. Though some things might take a little longer to load, there's nothing wrong.
[Galaxy Ace S5830 General] SuperAce609:

[Galaxy Ace S5830 General] phil boob:
So simple its genius

Why did I not think of this,

I just wanted more power!!!!!! but underclocking and using the on and off screen profiles in the setcpu app have given an amazing extension to the aces battery. Ok I have noticed that opening the bigger folders on the sd card is alot slower but hey I can live with that!

Havnt played many games on 480 mhz but its easy to change back up to 800 mhz if needs be.

Just wanted to say thanks op!!

I'm calibrating battery, now am discharging it until it turns off the phone, my question is if i charge it non stop until it says 100%, unplug it and then turn on the phone, or turn it on and then unplug it? Thanks!
[Galaxy Ace S5830 General] SuperAce609:
No, when you boot up, a little bit of battery is lost. Leave it plugged while it boots until it shows 100% again then unplug it around 10 mins afterwards.

smartass governor

m using CM 7.2 on SGA, battery life is very poor... this thread is really gr8..:)

i dnt have smartass governor on my device...

how to install smartassv2 governor..plz help..

any link.. :)
[Galaxy Ace S5830 General] SuperAce609:
I can name you some kernels but you're gonna have to look for them yourself. One is Blackhawck and the other one is Fire Kernel. Look for them in the development section.

Great tutorial thanks a lot.
[Galaxy Ace S5830 General] Peteragent5:
BTW, the heapsize is memory (ram) that apps can use. The bigger the more multitasking. Stock ROMs set the heapsize to: 64m

But I think lower is better for battery (but not too low. 48m is best), because it limits the phone from using so much ram, thus phone saves battery ;)

Deep Sleep

But how can CPU Spy show how long the device was in Deep Sleep mode at all, when its process has been stopped? I think your argument is not true.

Concerning the battery saving guide: When you set a minimum clock speed in SetCPU, that the processor should run at during Screen Off, that means that the processor won't go into Deep Sleep mode, isn't it? And that is bad, because the most battery is saved in Deep Sleep mode and not at 122MHz (that is the minimum speed that i can choose in SetCPU)!

I allready tried this method and it did not saved battery at all - it made battery discharching faster! CPU Spy shows that the Deep Sleep time was only about 20%. In my opinion that is the prove that the method ist not useful.
[Galaxy Ace S5830 General] SuperAce609:
Whether CPUSpy shows it or not, this has been proven by me and everyone else on this thread that it DOES save battery. Does it work for you? Maybe not. Don't say it doesn't then. You're just the unlucky 1%. This guide is based off what I used as settings and what gave me results, you can modify them to your needs if you'd like.
[Galaxy Ace S5830 General] neptern:
Using CM9 but soon CM10.Will try the tips to extend battery life:laugh:
[Galaxy Ace S5830 General] menschenhain:
What is your Deep Sleep time?

My problem is that it is not logical that that this method saves battery although it prevents Deep Sleep and forces min. 122 MHz ...
[Galaxy Ace S5830 General] SuperAce609:
It might be illogical but it works. The deep sleep time I'll show you won't reflect this tweak since I don't use it anymore. I bought a new battery and I don't really have the need to. I'm using 122-806 Smartass V2.

[Galaxy Ace S5830 General] menschenhain:
Hmm, obviously it works for many people... as i see everyone is enthusiastic about it.. well, it did not work for me.

BTW here on XDA is a thread with all CPU governors listed and explained:

http://xdaforums.com/showthread.php?t=1242323

Concerning InteractiveX governor:

"As you can see in the summary, this is Interactive with some modifications by imoseyon. Now instead of using the dirty SetCPU profiles method of locking the frequency to minimum when phone is asleep, the own governor will do that which is a cleaner method and with a better ramping management when coming out of sleep. Basically, it has Interactive's performance with better battery."

Smartass and SmartassV2 obviously do the same thing.

Seems like SetCPU profiles are not needed anymore...
[Galaxy Ace S5830 General] SuperAce609:
InteractiveX makes the phone laggy as hell which is why I don't use it. Smartass V2 keeps a perfect balance.

I have underclock my Samsung Galaxy Ace with 2.3.6 + cf-root 84ex with setCPU with these settings:

Main: max 480, min 245, smartassv2

Profiles:

In Call: max 480, min 245, smartassv2, priority 90

Screen off: max 122, min 122, powersave, priority 85

Battery charging: Any, max 806,min 245, smartassv2, priority 80

Battery <=50%: max 320, min 122, conservative priority 70

And this is what i got (see thumbnails)

around 8hours (between ~7:15am and ~3:15pm), before underclock, after 4-5 hours I had to plug the phone to recharge batery.

I will test on monday using waze...using it the battery goes to 15%-10% just driving from home to work starting with full charge.

I don't know why:

1. Opera doesn't appear as Facebook and Maps, in the morning I was using Opera around 40min playing Ikariam :D

2. When the level line goes yellow, seems there is no activity (continuous blue line), but the fast fall from green to yellow occurs because I was using Facebook and Opera.
