Batter lasting longer

TRY;

1. format you SDcard and ExT sd card

2. install Odex GB JVB Rom using Odin

3. Root with Chain kernel

4. Install minimum APKs ie only basic required apk

5. Keep it charging as much as possible for first 3 days

result Battery last 2.5 - 3 days after 3rd day with moderate use

I've 2 SGS but found it react differently to same ROM, 1 will drain faster but another will not and opposite on other type of ROMs. Basically it will depend on the type of ROM suitable so keep trying till you hit jackpot.

BUT owner of SGS will keep trying new ROM that is why we are on Android and owning a SGS.
[Galaxy S I9000 General] habylab:
Reverse if anything. Faster means more power, which if on same battery (which it isn't) would be worse. Battery increase should be proportional to higher performance though.
[Galaxy S I9000 General] Entropy512:
FYI, the battery "calibration" in the original post is misinformation. It is attempting to apply things that worked on HTC devices that had coulomb counter fuel gauges to devices which do NOT have a coulomb counter fuel gauge.

See http://www.maxim-ic.com/datasheet/index.mvp/id/6621 for information on the fuel gauge of our phone. Note specifically, "Unlike traditional fuel gauges, the ModelGauge algorithm eliminates the need for battery relearn cycles and an external current-sense resistor." (In our phone, the fuel gauge is integrated into the MAX8998 PMIC, however, it is functionally 100% identical to the MAX17040, to the point where our kernels use the MAX17040 driver.)

However, our fuel gauge does sometimes "flake out". Here is the appropriate debugging technique if your fuel gauge makes sudden drastic changes in percentage:

http://xdaforums.com/showthread.php?t=1209087

While it was written for the Infuse, all of the original GalaxyS series use the same MAX8998 PMIC.

I have problems with the battery life too.

I'm on Boogies Miui 3.1 with the latest FuguMod Kernel.

The Battery is empty after 2-3h of surfing with 3G.

The phone becomes really hot near the Simslot.I always thougt rhis is the heat of the Cpu, but this not the case.When i switch off mobile data and use wifi instead the phone dont become hot and the battery last much longer.

I think this could be a hardware issue,like a umts amplifier that is not working properly?

What do you think?

(sorry for my english,hope you can read / understand everything...)
[Galaxy S I9000 General] SvenGWK:
please delete this post
[Galaxy S I9000 General] dachau:
@SvenGWK: this is most likely because of missing power-save functionality in CM7 / MIUI. Samsung ROMs have a better battery life because of the sleep-mode and a better power management, that CM7 lacks yet. But there seems to be progress, as far as I got hold from the Insanity CM thread.
[Galaxy S I9000 General] SvenGWK:
Hmm, i have checked the used power states with cpu-spy.the phone is always in deep-sleep mode when the display turns off.800 mhz are beeing used during browsing. i dont understand why there is no heat when j use a wifi connection instead of 3g. how much hours ov continous surfing via 3g are "normal"? Is it comparable to the talk-time? By the way-now my battery is empty again. After 4.5 h (2h surfing via 3g)...
[Galaxy S I9000 General] AdNaNsa:
Message for @bokbacken because he have same problem but I need help from all. :D

Hello, how are you? Sorry for my bad english, I have question for you. Last weak I buy Samsung Galaxy S and my battery life is poor, phone didn't last 9-10 hours in sleep mode on a full charge! I read that you had the same problem, what have you done to solve the problem? I do not know what to do, I tried CyanogenMod7, DarkyRom last version, various kernel, various modem but nothing, consumes 10% of the battery for an hour :(

Regards and best wishes, I hope you will help me because I don't know what to do else. Thank You!
[Galaxy S I9000 General] emailrex:
Well it certainly helps in one or other...

Thanks for the sharing mate. I could at least pickup one thing from it (62% setting on screen filter.

Another thing to share is that all you guys out there with battery drain issues should definitely give a try to an app called juice defender ultimate, it has proven life saver to me at a lot of instances. Does really work wonders on saving battery and at the same time it's intelligent enough to keep connecting to the data services so that you don't miss up on your mail or other sync.

Other thing you guys can try is try different modems cuz it's something i have googled and found out and also heard from gurus over irc chat to be a major reason for battery drain issues. Try googling the right modem for your phone and your country. As far as i know if the modem is right for your model flashing different modems will do no harm to your phone or data and you can always revert back to the original one nothing works.

Alright then...more sharing and more peace to ya all...:)

Must say i have best battery performance ever since the new ICS builds that are out. Might be worth giving a shot for some ?

I miss an app, Screen Off & Dim! I think an app like that would help alot.

[Galaxy S I9000 General] zoubidou:
if you would read everything and especially go to the links included you would understand, but obviously that's to much asked for.:mad:

This is crazy und this threads just is going on exactly like the other ones, people come here to complain. why do they do this? they don't read anything, just complain!!!

If they don't like it they should go back and to KIES update and keep it that way.
[Galaxy S I9000 General] mithunjo:
Don't see any difference. Is it me or is this battery issue getting worse by the minute!
[Galaxy S I9000 General] zoubidou:
could you please at least install the free version of the systempanel (from the market).

at least it will give you some ideas.
[Galaxy S I9000 General] mithunjo:
I'm having the FULL version! I'm not getting any help from that either. What's the use when all ur Apps show less than 3 pc and the top Apps among them are all system processes etc.
[Galaxy S I9000 General] jackall:
Good Morning everyone, and hope everyone is having a wonderful xmas.

For todays report, only difference from yesterdays setup is I am now runninsg Hardcore's K12C kernel (flashed yesterday eve, before a night's charge).

When phone got off the charger this morning at 7:45 am, it was at 99% (not at 98% like yesterday). I think this was the effect of bump charging it a few times yesterday morning.

After seeing Hardcore's post here (Thanks for taking the time of looking into this thread btw), I also disabled usb debugging. (Any insight why this should be causing the issue would be greatly appreciated here.)

Time is now 11:09, battery is at 93% after 3 sms's and 2 short phone calls. I think this is good for now. (hope I wont jinx anything) :).

In my sgs-info --> Battery usage --> Network Usage I have got again the full Blue bar from process '0'. Along with 50% android system and 40% Dialer.

P.S. I have 3G on all the time, and no wi-fi on

Will report later on with more details.

Wish everyone a fantastic christmas.
[Galaxy S I9000 General] bokbacken:
HEY!:mad:

I think you should take it easy, obviusly you haven't read this forum, or you don't understand what it is.

I don't agree with you that people only come here to complain, a few of course will do that, and it's ok, soon we might be able to help them.

I see that you got upset, but I don't wan't to see this attitude in here, I REALLY MEAN THIS!

So take it easy, and try to control your anger.

WIFI toggling

I think i have one explanation for wifi draining: When i have gtalk opened and i switch from H to WIFI (sometimes) gtalk never gets connected again and it retires all the time to connect. In that time i don't get mail notifications so maybe there are retires over there too. interesting....
[Galaxy S I9000 General] zoubidou:
If you have the full version than look at the plots compare times adn cpu usage exactly. you will definitively see differences.

then you act upon your phone.

Switch WiFi off, and leave 3G on for lets say 1 hour or 2.

check again.

Switch 3G off and Wifi off, again for 1 or 2 hours.

Switch Wifi on and 3G off an so on.

and each time check the CPU and the battery drain plot.

maybe you want to write things down to keep some track of it.
[Galaxy S I9000 General] mithunjo:
I'm not really getting what to check here. Could you help..
[Galaxy S I9000 General] amwebby:
I was looking at the wifi settings and noticed it was constantly scanning for networks despite already being connected to my home network. I've turned Network Notification of and after 15 minutes there is no battery drain whereas before it was draining at 1% every 2 minutes.

Could this be it? Will report back later.
[Galaxy S I9000 General] amwebby:
Update. It is still constantly scanning for networks. Most annoying and appears to be no way to turn that off.
[Galaxy S I9000 General] mithunjo:
Exactly. I'm thinking this was the way it's always been..
[Galaxy S I9000 General] amwebby:
If that is the way it's always been then this can't account for the battery drain. The frequency of scanning is constant, which seems redundant especially when the phone is already connected to a wireless network.
[Galaxy S I9000 General] razzda:
Just an update regarding stock JPY with Voodoo 5.0.3. After a complete charge, I reset the battery stats via recovery.

Wi-fi was enabled, but I was nowhere near any access point, so anything data transmitted to the device was via HSPDA. I did approximately 10 mins of surfing with Skyfire and sent a few text messages, but made or received no phone calls.

The drop in charge has been fairly linear.

T=0 hours, 99% (after a full charge to 100%, I installed juiceplotter)

T=1 hours, 98%

T=2 hours, 97%

T=3 hours, 95%

T=4 hours, 94%

T=5 hours, 91%

T=6 hours, 90%

T=7 hours, 88%

T=8 hours, 85%

T=12 hours, 78%

T=16 hours, 66%

T=20 hours, 60%

T=24 hours, 57%

Quite a steep drop whilst surfing with Skyfire over HSPDA. It dropped 8% charge in about 10 minutes.

In OS monitor, I can see 106 processes running. CPU usage is around 20-25 %.

I ran the *#*#4636#*#* command and got the following (sorry for the approximate translations):

"Since Unplugged"

"Running 9,1%"

"Screen on 6,4 %"

"Phone on 0,3 %"

Wifi ON 100,0%

Wifi Running 100,0%"

Let me know if there is more information I can provide.

voodoo lagix suck battery very hardly.

and not giving such results as OCLF :( (1400 in voodoo vs 1800 in OCLF)

y every cooked rom uses voodoo ?:)
[Galaxy S I9000 General] amwebby:
I haven't done any flashing via Odin, only standard kernel via Kies. I just wish I could find someway to turn wifi scanning off without turning wifi off. I never noticed the frequency of wifi scanning before so am unsure if this has changed. Perhaps someone who has not upgraded to JPY or JPX could report?
[Galaxy S I9000 General] zoubidou:
i gave figured this out since a longue time already, and someone just said to me that this is a typical android behaviour.

but it is totally stupid behaviour. once a system is connected it should not send any network discovery beacon. The thing is I have not figured out how to monitor this on my network, because every monitor is just monitoring his own card, and not the others.

But i will figure it out with some network and wifi detection and hacking tools.

I have just changed the AP scanning option in wpa_supplicant.conf

and changed it to 0. I.e; driver takes car of scanning AP selection and so on.

I still scans like mad every 5 seconds. I think the wpa supplicant is the cause of this.

besides that it connects normally.
[Galaxy S I9000 General] ReiKo90:
Yes, I know - I was wrong.
[Galaxy S I9000 General] ahhong88:
I think we can't judge everything from the quadrant score. Currently I'm using darky v7 without lagfix, quadrant score is only around 1200, but the performance is very smooth.
[Galaxy S I9000 General] fire314:
I've definitely seen an improvement in battery life after installing:

Kernel: SpeedMod K12a

Modem: JPA

Wifi: JPA

over Doc's 6.2 JPY WIPE. (No Lagfix, First 4 Kernel Tweaks, BLN)

Lost only 2-3% over 9 hours of idle last night.

I do feel that part of the problem is our obsessiveness to squeeze absolutely every last micropercent of performance out of our Galaxy S's.. hence to obsessive flashing of new ROMs and the Obsessive Compulsive fixation on the value of the Circle Battery Mod Percentage reading. I bet if less people had the Circle Battery Mod then less people would freak out every time the phone used up a few percent of battery while surfing the net, etc..

At the same time however, there does seem to be a significant difference in JPX/Y battery drain, and if we want speed and battery life, we must find a fix. I found mine and it seems to work nicely for the moment.
[Galaxy S I9000 General] mopodo:
Using Darky's v7 Gingerbread Edition with JPA Modem

The Phone respones to pings when the screen turned of, sleep policy is set to "when screen turns off"

The answers come but not that fast as when the screen turned on.

avg when screen turned on 60ms, when screen turned off 500ms

1h since I unplugged my SGS

8% percent drained in total

85% screen

Wi-Fi 7%

Cell Standby 6%

Phone idle 2%
[Galaxy S I9000 General] SoSJokerSoS:
I am testing this Wifi bug now.

I suspect Wifi because when i turn my phone into stand-by it drains almost nothing, but when i turn wifi on and turn my phone into standby, it drains a lot of battery.

I will report later. Now my phone is currently at 92%. I downloaded battery snap and keep my phone in stand-by, and let wifi on for 2 hours. I will show you the results later.

[Galaxy S I9000 General] MAMBO04:
Bloody interesting :D will test wifi etc later on, but kudos for making this thread!
[Galaxy S I9000 General] salivaman:
Fact: When wifi policy is set to "when screen off", it switches the wifi off only after 15 minutes.

This is not a bug and android designed it this way. Trying pinging it 15 minutes after the screen is turned off. You won't get a response.
[Galaxy S I9000 General] mithunjo:
Any breakthroughs anyone? I mean anything conclusive?

I earlier had drain only when I was using the phone Wifi or 2G. But 2 hours before i left the phone for charging now, There was drain even when the screen was Off (10% in an hour).

I have applied the JPA Wifi update 3 hours back.
[Galaxy S I9000 General] SoSJokerSoS:
Nope, still no improvements so far. Applied it yesterday!
[Galaxy S I9000 General] dbraaker:
ive got a little more input for the miscalibrated battery thing. sometimes when i flash a kernel the battery level has changed dramaticly. i just upgraded to k12c kernel with around 40% batttery and it jumped up to 60%. looks like miscalibration on the first glance, but now my phone charges up to a much higher voltage. yesterday my phone charged to 100%, voltage jumped up to 42xx mV from 40xx when the phone reported full, unplugging lead to a drop of the percentage gauge to 98% and voltage dropped immediately to 4020 mV. now i am at 4097mV and 78% gauge, the phone is charging a lot longer than normal. somehow it seems to be possible to recover "lost" capacity by kernel flashing ;) probably you can do it the wrong way just aswell, as stated in the old battery calibration thread.
[Galaxy S I9000 General] SoSJokerSoS:
did anybody test speedmod K12C?

is it stable?

may i use it with darkys rom v7?

is it battery efficient?
[Galaxy S I9000 General] zoubidou:
it is stable

it works with darky's rom 7

don't know yet
[Galaxy S I9000 General] bokbacken:
Hi again!

@Vo1 could you back this up with some data? btw heard this before? "Not that Quadrant means anything, but my score is:..."

Why is that? We can measure the result and all of us want to have the fastest phone, not that it matters anyway:rolleyes:

@ahhong88 "Not that Quadrant means anything, but my score is:...":D

@fire314 I think you are right about the obsessiveness part in a way, but we do also have the big drainers, as you yourself have found out.

@mopodo nice to se some results, don't forget to check salivaman's info

@SoSJokerSoS nice of you to drop by, look forward to coming reports.

@MAMBO04 Started it in my selfinterest:rolleyes:, really I missed a thread like this

@salivaman thanks for the insight

@mithunjo do you have any syncs active, give us some detaild info on your setup, email, facebook, weather updates, widgets and so on

And again I will say: We must have a lot of patience in this thread, get some data before posting a revolutionary find, let's stick to the facts!
[Galaxy S I9000 General] SoSJokerSoS:
ok it has now been exactly one hour since i turned on WIFI. I did nothing, i have just turned my phone into standyby mode.

My current battery status is: 84 %

So from 14:00 o'clock to 15:00 o'clock it dropped from 92% to 84% in Stand-By.
[Galaxy S I9000 General] bokbacken:
Interesting!

We really need to get data of mV vs % from a lot of phone to make a comparison, lets all fully charge our phones and start reporting a couple of different levels:

100% for everybody that otherwise report mV and highest % you do get.

then mV at:

95%, 90%, 75%, 50%, 25%, 15%, 10%, 5%

Maybe we will understand the impact of battery calibration.

In this history also include if you reflashed at 100% or not
[Galaxy S I9000 General] dbraaker:
i dont really know if those numbers mean anything tbh, who knows if voltage is measured correctly.
[Galaxy S I9000 General] SoSJokerSoS:
how may i add local screenshots?
[Galaxy S I9000 General] SoSJokerSoS:
Here you see my battery history

*Ausführen = Execution

*Bildschirm ein = Monitor on

*Akkuverlauf = Battery history

*Seit letztem ausstecken = since unlug of the powercable

now i will turn WIFI off, an leave it for about 1 or 2 hours in Stand-By. Let's what happens.

btw. i am using:

-Darky's Rom V7

-PDA: I9000XXJPY

-Phone: I9000XXJPY

-CSC: I9000XAJAPX

-Voodo Kernel + Lagfix enabled -> ext4 FS
[Galaxy S I9000 General] bokbacken:
Pretty sure the mV is correct within a few% these AD converters on the charger has to be accurate otherwise the battery could be damaged, I do believe this is info from the charger circuit. This could of course be verified with anyone having a multimeter.

Edit:

:mad: Don't remove the battery during the shutdown of the phone, WAIT untill the configmation "buzz". When restarting the phone after measuring the battery I got the famous Samsung S logo + "bzz"....."bzz bzz"...

right now I'm reflashing ROM and Kernel, will be back later on. :mad:

:mad::mad: Wasn't enough to reflash, it corrupted tha data partition with all the installed apps, so factory reset format data, reinstall again :mad::mad:

BTW did I mention that you should WAIT for the confirmation "bzz" after shutdown before pulling the battery??
[Galaxy S I9000 General] SoSJokerSoS:
Update:

At 15 o'clock i turned off wifi, so only 2G was turned on. I left my phone in stand-by mode till 16:43.

My current battery status is: 84%

As you can see, it drained nothing! So it has something to do with Wifi, whatever, maybe a driver bug, i dont know.

(since i flashed JPA phone file i dont think that is a driver bug.... maybe kernel? software bug?)

Watch my screenies!
[Galaxy S I9000 General] kootheancheah:
Thanks for the welcome. I really like to solve this problem, too. Been bugging me ever since I changed to darky's v6 and v7.

I installed hardcore's wifi dxjpa today and tested it for a short time.

Before installation, battery level drops 7%/20 mins (84%-->77%)

After installation, battery level drops 7%/20 mins (86%-->79%)

Conclusion: No difference whether the modem is dxjpa or xxjpy.

Anybody else tested it and has similar results??
[Galaxy S I9000 General] SoSJokerSoS:
yes, i get same results
[Galaxy S I9000 General] NetCopAD:
Mate, the WiFi draining was addressed by Hardcore yesterday in his K12A kernel. Just flash his latest K12 kernel (at the moment this is K12C) and you are done. It was a leftover debug message in the kernel wifi driver.
[Galaxy S I9000 General] bigmo7:
Oooooh that's tempting, might just disable Voodoo and flash and see what it's like ;)
[Galaxy S I9000 General] SoSJokerSoS:
nice, i will test it. Thanks for this information
[Galaxy S I9000 General] kootheancheah:
I am pretty sure it's has to do with wifi and xxjpx/xxjpy in my case.

I never had this battery drain problem with wifi when I was on dxjpa.

I m now using darky's v7.

When my phone is on standby and wifi off, it hardly drops at all. Overnite for 7 hours, it drops 1~2%. However, when I switch on wifi and surf, the level drops like crazy.

My screen brightness has been adjusted to the min and data is always off.
[Galaxy S I9000 General] kootheancheah:
Appreciate it if you could report your test result with speedmod k12A here.

I am eagerly awaiting your positive results. ;-)
[Galaxy S I9000 General] SoSJokerSoS:
i am currently flashing.

Update:

Flashing succeded, testing previous case for 1 hour.
[Galaxy S I9000 General] wuffa:
I had a mail account set up to never sync, and while it never did, it was still "talking back" to the exchange servers every 3-4mins (I checked the server logs).

I knew this because I changed my password and something was locking my account out all day, so could just check for failure audits.
[Galaxy S I9000 General] suntzu123:
Small update,

Power problems are because of bad Rom, Bad Kernel, bad modem...

... Easly solution for idle power drain. Use BUJP5 modem. In JPY it drain 1%/hour, now it going 1% per few hours.
[Galaxy S I9000 General] SoSJokerSoS:
Nonesense! First of all, brilliant Rom, brilliant Kernel, and maybe a bad modem. Neverthless i replaced my modem file. (now i use JPA modem, and it didn't resolve the problem)

[Galaxy S I9000 General] ldjh1985:
Hello all , TOP THREAD

Im running Darkys v7 with k12c kernel, battery is okish, Ive done the following, drained battery completely, fully charged, reset battery stats, disabled usb debugging, disabled wifi network notification and ive lost 12%, ive been surfing the web on the wifi the whole time...
[Galaxy S I9000 General] bokbacken:
Thanks for your concern, this might help some guys, but there are not really any easy solution, I have some links in post #3 about different modem, pele78 have compiled a list with some user experiance regarding signal strenght batterylife and other info, remember to check back on my first 4 posts, they are being updated from time to time.

My phones is almost back to how I want it after my little mishap, was a good time to change my default rom's a bit to have hardcores latest kernel and I added the JPA wifi fix as well, but I did reflash at something like 60% batt, how will this affect me? We'll see.

BTW Have I mentioned: DONT REMOVE THE BATTERY UNTIL YOU GET THE "bzz" CONFIRM AFTER SHUTDOWN!
[Galaxy S I9000 General] SoSJokerSoS:
By the way what is actually the difference between speedmod k12c 500hz and k12c 256 hz?
[Galaxy S I9000 General] bokbacken:
Welcome to the thread!

Thanks for the report, but there is one tiny little detail missing from it:

How long did it take you to loose these 12%?????

Otherwise OK.
[Galaxy S I9000 General] bokbacken:
The hz is Linux kernel ticker (kind of) so the higher the freq the smoother the system.

256hz = 256 interupts/sec

500hz = 500 interupts/sec

Battery affect is said to be minimal (Yes, I did write "said to be")
[Galaxy S I9000 General] ldjh1985:
Hi there

Took roughly 70mins, now been surfing for 90mins and im down to 85%, I also forgot to mension I turned off auto sync for my gmail .
