Only during the day. But at night i turn my phone wifi off. This is what I usually do after I turn the wifi off: I go to Settings >> Applications >> Manage Applications >> Running.

From there I force close some third party apps that usually requires wifi connections like apps with ads because I notice that my battery drains so fast it sometimes only lasts about 8 hours.

One example is the craigsnotifica app. Its default setting is set to check updates every 5 min. With that app running in the background, my battery drains 10% every hour. That is where I got the idea of closing third party apps (*Note: just third party apps!!!) to save battery consumption.

Reminder: Please do avoid closing system apps 'coz these might be doing something VERY VERY important in the background.

Edit: Also check the path above before you turn on your wifi, then check it again after turning it on. You can verify some apps starting to run in the background even if you did not start them in the first place. (Maybe those apps has wifi-on-change broadcast receivers in their code, you know what I mean android developers)
[Galaxy S I9000 Android Development] Travel_Mate:
Looks like everybody is reporting bugs, so i'll take part too:). So updated via Kies, wiped before update and after.

Cons:New facebook app, creates second facebook sync account, contact app not closing after use - remains in memory, after disconnecting from charger battery drops to 99%, 15 min later to 96%. I'm comming from JPP/JP7 and this was not the case before,my battery stays 100% at least 10-15 min after disconnecting.

Pros:Really fast without lagfix, there is the new setting for the lock screen wallpaper, but also nobody mentioned it, now we can use a 480x800 desktop wallpaper - this is new and cool. Kies air is usable now, before it asked for permissions on each move of the mouse.

Also, am I mistaken or the fonts in contacts and messages are bigger?
[Galaxy S I9000 Android Development] HExa_ss:
My Battery life on JPU was Bad :( ... But now On JPX is really really good :D:D ... Is JPY have same as JPX battery life? (Sry For My Bad English :( )
[Galaxy S I9000 Android Development] wcg707:
For the last time, please understand that the decoded jpz resulted in JPY.JPY.JPY.tar. This is the same based being used for all the JPY rom. The kernel build no is root@sep-51 #1.

As for the JPY.enc, there is no decode string given. To decode, download enc file and this. Extract in the same folder and just type decodetest 'encfilename.enc' decodestring
[Galaxy S I9000 Android Development] AMDPOWERFIST:
aaaaaaaaaaaaaaaaaaaaaaaaaa
[Galaxy S I9000 Android Development] bohdans:
Mine is working fine, I flashed from JPU to JPY and kept market place etc....
[Galaxy S I9000 Android Development] ikanikolai:
I don't have problem with battery and also if I switch off the Wi-Fi, then I check in the running process, it is not running. Maybe you should do a factory reset.

Also if you have facotry reset, the quadrant result is better (I think because the phone rewrite all cache, etc.)
[Galaxy S I9000 Android Development] howzit:
I installed this via Kies and the registry patcher hack and Kies keeps reporting that my current version is JF3 :/

Other than that, it's JPY is great :)
[Galaxy S I9000 Android Development] kg3:
Was going to download JPY from samfirmware and it was 158mb but the link in this thread is 291mb. Why such a huge variance?
[Galaxy S I9000 Android Development] gicgi:
"remove the plug at 100% see its %98 in a second" problem is still there till jpu. how cool is that?
[Galaxy S I9000 Android Development] melorib:
I installed JPY from JPX last night, battery went more than 50% over night, and wifi was on in the morning, change the setting to NEVER, hope it improves...
[Galaxy S I9000 Android Development] erahk64:
Select Settings > Wireless and network > Wi-Fi settings > Menu button > Advanced > Wi-Fi sleep policy.

Default on my phone is "Never", you could try to set it to "When screen turns off".
[Galaxy S I9000 Android Development] melorib:
I mean to ""When screen turns off", of course... :o
[Galaxy S I9000 Android Development] miro666:
Because is on Samfirmware is compressed in RAR, but here is normal TAR data...If you make unRAR you will see equal....

Regards
[Galaxy S I9000 Android Development] tma200:
Getting the same here with JPY flashed over JPX. Anyone else not seeing the WiFi turn off even when set to turn off with screen in the advanced settings?

Idle battery use is great when WiFi manually disabled (87% to 85% overnight, 2G data enabled, couple of emails received)
[Galaxy S I9000 Android Development] ludovicianul:
I'm on JP7 now and I don't have either download or recovery mode working. Is there any chance of getting them working if I update to JPY using the Kies Patcher?
[Galaxy S I9000 Android Development] Adevem:
it turns off after 15mins by default unless you change it.
[Galaxy S I9000 Android Development] tma200:
Except it doesn't appear to be doing so, and draining the battery as a result. If people generally aren't seeing this peculiar WIFI behaviour with JPY I'll see if a factory reset cures it.
[Galaxy S I9000 Android Development] j.go:
The low-level package of JPU contained updates to the bootloader. There were some reports on the JPU thread that flashing that package gave 3-button recovery/download to those who previously didn't have it. You will have to ask there. On the other hand, I'm not sure how you'll be able to flash your phone without 3-button combo working...
[Galaxy S I9000 Android Development] SnoopyDog:
Yes, the full (low level) JPU package contained the proper boot loaders with 3 buttons working. But you can easily and safely get your phone to download mode with the special USB jack. Still prefer this rather than using the 3 buttons.

The USB jack is the most preferred method for putting your phone to download, you don't need to install any patch (which also may fail) - and it 100% works.
[Galaxy S I9000 Android Development] falkontre:
I confim...I've recovered my phone with this "trick".
[Galaxy S I9000 Android Development] bdl1969:
I'm finding that the WiFi on mine is turning off if I set it to 'Never when plugged in'. The 'when screen turns off' setting doesn't seem to be working.
[Galaxy S I9000 Android Development] ludovicianul:
I'll go for this trick then in case something happens :)
[Galaxy S I9000 Android Development] pixie77:
You need to re run the patch but now select false, it will then read the firmware on the phone again.
[Galaxy S I9000 Android Development] nicpol7:
updated now from jpo(with kies with registry hack) which was perfect in terms of battery drain

jpy is much faster..but battery drain is a problem

from 93% to 83% in an hour without even a phonecall..

with jpo my galaxy s lasted for 3 days..
[Galaxy S I9000 Android Development] vladtdr:
WIERD

I have the jpy, but my RAM shows only 304 available and the quadrant test is around 1000
[Galaxy S I9000 Android Development] galaxoid:
You don't have JPY or at least you don't have JPY kernel.

Maybe you flashed some kernel to "fix" something or root the system?
[Galaxy S I9000 Android Development] vladtdr:
you are right thank you so much, what do you recommend? flashing just the kernel or entire firmware?
[Galaxy S I9000 Android Development] basti107:
same problem here with jpu jpx etc
[Galaxy S I9000 Android Development] phalanger:
Oh please, not more of this sillyness. Battery stats are uncallibrated and thus very inaccurate after flashing new firmware. Give it a couple of days and a couple of charging cycles before drawing any conclusions. This is not new guys.

People that test their GPS indoors and test their battery in the hour after flashing a new firmware make this forum's visitors look dumb :<
[Galaxy S I9000 Android Development] guijarrelson:
That's look so important... This update came from Kies? A security fix?
[Galaxy S I9000 Android Development] nicpol7:
i didnt test the phone immediately after the upgrade..sorry for my english

i just say that on standby with black screen battery drains about 8 tp 10% pr hour with wifi 3g and etc all deactivated ...
[Galaxy S I9000 Android Development] QBANIN:
Same problem here... endless "connecting" :(
[Galaxy S I9000 Android Development] houlid:
I upgraded last night to XXJPY, the battery is very good. With all deactivated (wifi, 3g, gps) for the night and normal gsm, the battery almost stayed constant, which means 1% per 8 hours. :)

Even if wifi/3g/gps are deactivated, there may be some apps, running in the background, trying to connect. So you can use some task manager/killer to monitor these running apps. You can also have a look at the battery stats by going to Settings-->About Phone-->Battery use.

I will test it now with 3g activated and gmail push on (syncro).
[Galaxy S I9000 Android Development] nsa666:
I may be wrong, but I think FM-Radio sounds better with this firmware.

Ad Free works for me today. Some temporary problem?
[Galaxy S I9000 Android Development] houlid:
Yes, AdFree is working now :D, that was not the case this morning.
[Galaxy S I9000 Android Development] mithunjo:
So is this the best firmware among the 2 others before this? My concern is that in no time of me updating to jpy, samsung will release yet another firmware..
[Galaxy S I9000 Android Development] melorib:
Better too many than not enough... ;)
[Galaxy S I9000 Android Development] QBANIN:
Confirmed, AF is working now :)
[Galaxy S I9000 Android Development] Maddmatt:
I sent a few SMSs to a certain number and only one of them got through. Received messages from that number just fine. Made a call to that number and that worked fine.

Anyone else have a similar problem? Maybe just a problem with my network due to a storm.
[Galaxy S I9000 Android Development] ranwej:
Are you noticed, that there is no more scrollbar in internet browser? Or it's just my bug?? I want it back..
[Galaxy S I9000 Android Development] SiL3nTKiLL:
interesting stuff here...
[Galaxy S I9000 Android Development] seepage:
Never noticed there was a scroll bar before. I dont seem to have one on JPO
[Galaxy S I9000 Android Development] ombranera:
the bug of duplicate contacts from phonebook when you added receipt at sms or mms already rest :(
[Galaxy S I9000 Android Development] mithunjo:
When i click on the PDA button in Odin to select the tar file, the Odin application just hangs!! I tried it 3 times. Weird because i flashed JPU fine using Odin.

Can someone help me?

Edit: Workiing now. I moved my Odin folder to the drive where i had Windows. But i am not sure if this was the issue..
[Galaxy S I9000 Android Development] mithunjo:
Flashed to JPY just now. One question. In the initial phases of me using JPX , it was very snappy. But after a week or so, there was some lag. And so i went and applied the OCLF.

My question is whether even JPY would require OCLF for better performance?
[Galaxy S I9000 Android Development] Davith:
It was gone since JPU. A bit annoying but I got used to it.
[Galaxy S I9000 Android Development] ilbulgaro89:
Froyo 2.2.1 source released...

maybe we will see Kies release (without spoof hack) today
[Galaxy S I9000 Android Development] dadyal:
fab 2011 :)
[Galaxy S I9000 Android Development] melorib:
Last night, with wifi off, only used 2% of the battery... :)
[Galaxy S I9000 Android Development] rigor.m:
Updated yesterday via KIES, after a product code change to XEU and a factory reset.

Market still did not work right so SuperOneClick - rooted, market enabler and adfree for a bonus.

Speed is great, battery life is very good ( overnight 5% drain ) , browser still shows checkerboard pattern but works well.

I like this ROM a lot, finally Samsung is doing something about the (legendary) bad software support of its products...
[Galaxy S I9000 Android Development] Philio25:
Just flashed with KIES (spoof = true) and worked nicely, except for accidentally hitting German language with no option to go back on the post update setup :D

Seems very quick, equally as fast as with lag fax on previous rom (I had JPO).
[Galaxy S I9000 Android Development] zerozoneice:
can't seem to be able to remove cancelled events from Exchange calendar.

receives the cancellation mail but no option to remove from calendar.

only way is to remove manually or remove on PC (outlook) and re-sync phone calendar.
[Galaxy S I9000 Android Development] chrisjcks:
JPY is definatly slower than JPX ....
[Galaxy S I9000 Android Development] mad_scientist:
Battery drain definitely an issue for me on JPX and JPY. I noticed that it happens only when WiFi is on (I do not have 3G or other kind of data connection). I also noticed with *#*#4636#*#* that the phone does not sleep at all when this happens (even if I turn the screen off) and network transfer by "Android System" keeps growing.

I even went on and removed a bunch of apps from /system/app without any effect.

On a side note, I think it happens when the WiFi is on and connected but the network has issues (bad connection - from one room in my house where signal is poor - or no Internet access - at work I need to authenticate on some site before I am allowed internet access). I am not 100% sure about this but it does seem so.
[Galaxy S I9000 Android Development] chrisjcks:
Also, pulling down the notification bar is laggy and not smooth at all. (this is both JPX and JPY - JPO was fine & smooth)

I'm starting to think these 'are' test builds...

JPX is the fastest though, just shame about the notification bar.
[Galaxy S I9000 Android Development] alexhull24:
My notification bar was fine on JPO, and it's fine on JPX too. I flashed the whole set for JPU with Odin, then flashed JPX PDA and factory reset along with format of internal SD and clearing cache. Runs brilliant. 1200 in quadrant with no lag fix, everything now works too.
[Galaxy S I9000 Android Development] ludovicianul:
After flashing JPY with the Kies Patcher, the phone can still connect to Kies, right? Do you know if I can flash back JP6 over JPY using Kies Patcher and return to initial product code without problems?
[Galaxy S I9000 Android Development] amwebby:
I reflashed with JP6 from JPY using the reg patcher without any issues. If anything the system seemed to have benefited, with a Quadrant score of 1,000 whereas before it was 946. Flashed back to JPY and a Quadrant score of 1,250 when the slow start up and lags got too much.
[Galaxy S I9000 Android Development] NetCopAD:
Exactly my problem. My internet connection is also unstable lately and the symptoms are the same. Only solution so far - wifi off :(
[Galaxy S I9000 Android Development] masi0:
battery drain is horrible as well as mysterious "Process 0" in battery history/network usage...
[Galaxy S I9000 Android Development] sean2476:
I have had a few text messages failing too. Never had any failures on eclair or on JPO.
[Galaxy S I9000 Android Development] veay:
is it known on which build they are based on? jpx or jpy? or is it completely different?

I was reading the posts since now.. I'm waiting for more than a week now for the official release via kies..

Guess that all people who want 2.2.1 100% officially have to wait and look up every day in kies whether there is an update or not.. =/
[Galaxy S I9000 Android Development] FRLinux:
Any backup to this claim? Upgraded from JPX (full clean cache and format) and i find it snappy as with JPX. Also no battery drain for me.
[Galaxy S I9000 Android Development] AxeleroD12:
where can i download the csc file for jpy ?
[Galaxy S I9000 Android Development] tackygr:
My code is KOR now and Darkyys v.6 JPX ,if i do this trick,and then restore from CWM my current backup,will this change my code to KOR agan or it will remain XEU?
[Galaxy S I9000 Android Development] tomeks:
it should remain the one you set up
[Galaxy S I9000 Android Development] chrisjcks:
backup?

im a customer is all, and JPY has a noticeable drop in speed compared to JPX, mainly with app launcher and lag during switching of screens.

tested both throughout my work days, and JPY (to me) has a noticeable increase in lag compared to JPX.
[Galaxy S I9000 Android Development] ludovicianul:
Anyone has the "Not enough battery for update" with Kies? Any solution for this without Factory Reset?
[Galaxy S I9000 Android Development] tackygr:
i guess you are updateing through regitry hack,if so,just desable the check battery in the registry patcher.
[Galaxy S I9000 Android Development] :
Really like the idea of a different lock screen picture but such a shame it does not work with the live wallpapers :( I was going to customise one with an IF FOUND Tel. message on it.
[Galaxy S I9000 Android Development] ludovicianul:
kies is telling me now that the update failed, after downloading the files. I'm going crazy!!!
[Galaxy S I9000 Android Development] FRLinux:
I just benchmarked my phone on quadrant and linpack. Scores the same as JPX.
[Galaxy S I9000 Android Development] vladtdr:
i flashed jpy, factory reset after and my battery life is terrible, it was 50% when i went to sleep and when i woke up the phone was shut off because the battery was completely drain...without wifi on
[Galaxy S I9000 Android Development] ofulanof:
EDIT: Phone never sleeps.

Battery History --> Time spent without sleeping 9h 1m 41s

This is impossible, I hardly received 2 phone calls and installed CF-Root in 2 days. I could not have used it for 9 hours...

...

Even though I have lowered my installed apps from ~120 to 18 now on JPY, with my 3g/wifi/gps/autorotation/brightness sensor/auto sync OFF profile, the battery drains like HELL.

I went of in my pocket without doing anything. It lasted a total of 8 hours... Standby time..
[Galaxy S I9000 Android Development] Philio25:
Well I've only had this ROM for about 12 hours, speed is great for me, no problems, also I have never factory reset my phone since I got it (have had 2 different Eclair official ROMs, then official Froyo, then this) have tonnes of apps installed.

Big issue, battery life, I left work 4-5 hours ago (had full charge) and have had wifi turned on and it has killed about 2/3 of my battery already! I can obviously just turn wifi off but is there a fix for this?
[Galaxy S I9000 Android Development] _dsk_:
It would probably help more if people stated what method they were flashing (KIES or ODIN), if they were using different CSC, MODEM packages and what root methods?

The last few weeks ive gone from JPU to JPX and today JPY, so far its been a pretty smooth transition. Each time i used KIES i used the reg hack.

JM1 -> JPU (via ODIN)

JPU -> JPX (via KIES)

JPX -> JPY (via KIES)

I also did a factory reset before and after the flash, dont know if that helped. Restored my apps by downloading, nothing from backups like titanium.
[Galaxy S I9000 Android Development] SDeba:
So as I can see there is REAL problem with battery on JPY, is there any point in installing smooth system with battery drain problem?
[Galaxy S I9000 Android Development] melorib:
I always used Odin and CF-Root v1.3

Battery problems only when wifi is ON...
[Galaxy S I9000 Android Development] wireless09:
Same here...
[Galaxy S I9000 Android Development] wihan1:
There doesn't seem to be many who agree with you on the speed issue...i for one think speeds are the same.
[Galaxy S I9000 Android Development] yglodt:
Got JPX on my SGS.

Battery life is really worse than it was with JPO.

I noticed "Wifi sleep policy" says "always on", while I'm 99% sure Android defaults to "When screen turns off".

I set it this way now, we'll see the result tomorrow.
[Galaxy S I9000 Android Development] tackygr:
One thing know aout battery is that an iphone kicks the sh*t out of a SGS with JPX or JPU & JPY.

yesterday my friend was playing a 3D game for 3 hours,used internet,received calls,and played a multiplayer game with another friend for another 3 hours(scrabble),and left with his battery still going,and i dont even know if he came in with foul battery on his Iphone.

Whereas i was working and at the time he came i was on 95%,didnt use mine at all,and when he left 6 hours later i had less than 40%...i used the phone 20 times less than he did,and almost got to recharge it.

I feel proud having an SGS and generally it beats the sh*t out of an iphone in general terms,but after the JPU its nice and smooth but its rediculus to charge the phone 2 times a day.Lets hope someone will fix it soon...

Soz for the long post...
[Galaxy S I9000 Android Development] dk206:
yes the speed is great. Battery and power consumption, will have to test a bit more. Only had this for 2 days.
[Galaxy S I9000 Android Development] Davith:
Surely you must have an app that's draining your battery. Losing 55% in 6 hours is not normal behaviour. I'm sure it has nothing to do with the firmware (well, except if it's the Wifi bug).
[Galaxy S I9000 Android Development] kg3:
JPY isnt working for me. Came off JM9, re-partitioned and getting a black screen with random vibrations. Tried re-flashing again but same thing. Did factory reset and cleared cache too. Any ideas on how I can get JPY to work?
[Galaxy S I9000 Android Development] lgkahn:
I DON'T think not is full froyo version. You need to flash dome other full version first.
[Galaxy S I9000 Android Development] kg3:
I flashed to JPU which worked then flashed to JPY and the same problem. Oh well Ill stick with JPU until a new ROM is released.
[Galaxy S I9000 Android Development] lgkahn:
strange how are you flashing to jpy.. what is name and size of your file.. sounds like you have a bad file or download or something..

tar -tvf to see if the file is intact..
[Galaxy S I9000 Android Development] j.go:
Did you tick re-partition when you flashed from JPU to JPY? You're not supposed to.
[Galaxy S I9000 Android Development] gothfebrio:
+ no pit file
[Galaxy S I9000 Android Development] NetCopAD:
Hardcore found a bug in the WiFi driver. His K12A kernel solves the problem for me. Check it out ;)
[Galaxy S I9000 Android Development] kalki:
The best way is:

Flash jm8 with repartition 512

then fkash jpy without pit.
[Galaxy S I9000 Android Development] ludovicianul:
Guys, is really such a problem the battery drain. Evrryone has it?

I wanted to flsh this Rom, but now i'm not that sure.
[Galaxy S I9000 Android Development] zerozoneice:
charged JPY to full 100% last evening.

12 hours later down to 83%

wifi / apn both off, brightness @ minimum.

will test tonight with wifi ON and see how it looks after 12h.

phone being new i don't think i have 3-4 full cycles behind me, so the battery might still be needing some "training".
[Galaxy S I9000 Android Development] mithunjo:
This wifi battery issue is for real I think.

I'm having big battery drain issues with it. I have been having this problem on ALL froyo versions till now. But I think it's a little bit worse on jpy. From 100 to 90 in 35 mins.
[Galaxy S I9000 Android Development] mithunjo:
Hope someone posts a solution to this. And just to add, my wifi sleep policy settings is put to when screen off.
[Galaxy S I9000 Android Development] PAGOT:
Will be maybe difficult? Cuz not everyone has it. I for example dont. Wifi on (sleep when screen off) . And the drain is normal.

Just look for similarities what you have and dont have running. And install adfree.
[Galaxy S I9000 Android Development] chrisjcks:
ok, my kies has finally said a new firmware has been released.

this is without any patches or hacks.

UK - JPO > JPY

edit: performing the update now, and DAMNNNNN - Kies really does make me nervous doing it, when i use ODIN i dont have the same 'pressure' on my mind as the official software. LOL
[Galaxy S I9000 Android Development] SnoopyDog:
@mithunjo: I think, you'll have to investigate a bit. I definitely don't have battery issues with none of the JPU, JPX and JPY version.
[Galaxy S I9000 Android Development] got-petrol:
I'm on jpx should I update to jpy
[Galaxy S I9000 Android Development] GMH24:
As I also use Jpy I would like to share my experiences: I unplugged my sgs at 10am today, battery was fully charged. With very moderate use I am at currently 95%! I have autosync and hsdpa activated every 20 min (tasker)

Only my kernel is custom (current voodoo kernel), everything else is stock...

Merry Christmas everyone!
[Galaxy S I9000 Android Development] got-petrol:
Updated to jpy with Odin because kies will not work on my new i3 tower
