Yeah Jim, sure did. Always do with a new ROM. This only started a couple of days ago. No complaints about it up until then. Was running really smoothly, then it decides to start being a complete ######. Had trouble turning it back on last night after it reset itself. Apps FC don't bother me, it's just the resetting that's doing my napper in.

I have just had MAJOR Force close, and Battery issues...???

Everything was fine, I was writing an email, nothing different there, Then BANG! All hell let loose!

I restarted half a dozen times and the battery drain was more like 1% a second!!!

Something is seriously not right with Gingerbread!

I am going back to FoYo, but first some playing... Just flashed Cyanogenmod7, I will see how I get on with that, but I feel the Dark side calling 

[Northern-dj]

I did tell you it would happen 

Get your jig out Soup you might need it !!!!!!

JPY crahed first time.

i flashed JPK then JPY (Crashed) Needed jig But when it says can not install media pull battery and go into download mode, Flash JPK again (Fixes Bootloader Then JPY works fine after that )

I have tried to ask the question on XDA if any one had tried to fix this and got slaged off, and then it all kicked off on there lol

Which was funny.

Hope you con give you phone som TLC and get it back on the mend if any one can you can.

Thanks for your kind words mate. 

Thanks for the advice about JPK, good to know!

I am on CyanogenMod7 now  This is how Gingerbread should have been!!!

Can you post the link to your question on XDA? I could do with some cheering up!

Hi Guru's...

Need a little help, I have flashed my phone with the samfirmware I9000BUJV9 ## and seems to be working fine...but If I now plug the phone back into Kies it states my version as PDA:JV9 / PHONE:JV3 / CSC:JV5 (KOR)...this does not look like a EU version am I correct? and how do i go about getting one and that it will continue to work with Kies for future uploads.


cheers

Dan

(KOR) is Korean, if I'm not mistaken.

Don't know if this will work, but you could try to flash it back to 2.2.1 I9000XXJPY (also available on SamFirmware), then Kies should update it I9000XXJVO, which is the latest stock 2.3 (unbranded).

[Northern-dj]

Vandit there is no need His CSC has defaulted to KOR and needs to be changed to VOD You will need your IMeI number for this 

*#272*imei#* (Display/change CSC code) where it says imei put your long number in there then #* at the end youwill then get a menu scroll down to VOD then select it the phone will reset, Now if you have VOD firmware on which you then kies will then confirm you have the correct Firmware on.

JPY 2.2.1 Is a XEU firmware

Wish i was as brave as you for doing that is every thing working ?

Oh the post is god noes were now on the thread i'll have a look its probs 20 pages in by now 

[Danielpb]

Hi Thank you for the quick reply. i tried the imei input and i can only select KOR nothing else is displayed. I has any of you guys installed the same firmware?

@N-dj

Yes everything is working really well...  

Mate, I consider you to be one of the most knowledgeable people on here, compared to what you have done already, this is a walk in the Park!

I would recommend you follow jimc130's Guide in the resource board. I followed it to the letter and I had no problems at all. 

Think, Darky's Rom, and then imagine it to be 10x better! I have put all the screen animations and transitions to slow, really looks cool! Plus it's 2.3.4 JVK.

[Northern-dj]

Any screen shoots possible ?

[paulchambers061]

no native screenshot feature in CM7, I suppose that's why it's so mysterious.

crossing the streams, I mean threads now.

[Northern-dj]

Well I have always been tempted do co custom with darkys, But as I'm looking after three company's phones one of which are all SGS phones when i get this problem its a pain plus when my own phone goes questions get asked. 

I hope we do get a stable Gingerbread. Not all want to flash a long as it does what it says on the box 

[thesoupdragon]

@N-dj

Here are some screenshots of CyanogenMod7 for you!

Northern-dj & Vandit  just want to say cheers for the help I have managed to restore my phone back and can now use Kies again for my updates.

Just need to re-flash the phone with I9000XXJPY then change the CSC using the *#272*IMEI*# and setting toe XEU. This then allowed Kies to see an update was available.

so thanks guys!

No probs Dan! 

Changing the CSC doesn't work on all firmwares. Couldn't do it when my SGS was on Vodafone's 2.2, VOD was the only option. Which seems to be the case for KOR too.

For all those Boys and Girls who are suffering with the Samsung Gingerbread update...

I found this post on another well know forum which has had a lot of positive replies to this OP.

Basically it has transpired that the issues are due to two Samsung system apps, namely Software OTA Update & Samsung Account which to my knowlege are not required.

You will need to be rooted and use something like Titanium or root explorer to get rid of these apps.

Of course custom Roms such as Darky's have already got ridden of them hence why they don't have these issues.

VT

Anyway here's the original post:

There is a lot of threads going on about battery life related problems, let's try and keep everything in one place.

First we'll see how to fix some Gingerbread specific problems (JVB & JVK), followed by a bunch of general recommendations to save power on all ROMs (Eclair, Froyo, Gingerbread) and there is a guide to calibrate the battery.

Android OS bug on Gingerbread ROMs

This is the most annoying Samsung/Android bug.

A good few people have been seeing battery drain on Gingerbread. It comes randomly and apparently once it starts the only way to stop it is to reboot... But it comes back after a while

You can identify this drain by checking the Battery Use in Settings : if Android OS is above 20%, often between 40 and 60% of the battery consumption while your phone has been idle most of the time, then that's it.

The good news is that there is a fix  found in XDA: 2 system apps are responsible for this leak, here's what to do using Titanium Backup :

Find Software Update & Samsung Account, select them one by one and "Clear Data". Now you need to freeze Software Update (if you have the Pro version of Titanium Backup) or to backup the app and delete it. Since you don't delete the backup, it's like a freeze. (But keep the backup in case you want it back for some obscure reason)

Or simply use the default app manager to clear the data and Root Explorer to backup/delete Software Update.

If the Android OS battery drain comes back after freezing/deleting the 2 apps above then I suggest you read about the app below. You can back it up and delete it as well and see if it improves:

wssyncmlnps.apk (info) - make a backup in case.

Please share your findings posting in this thread so everybody can know.

Tricks for all Android versions

Other important things to improve battery life:

- Set Wifi sleep policy to "never" in Settings > Wireless > Wifi > Menu key > Advanced > Wifi sleep policy.
- Set Settings > Display > Animations to "NO or SOME animations" (thanks to Phazeman for that), you will still have the overglow effect and the CRT screen-off animations is you select "some"

Now a little bit of magic:

Toggle the airplane mode on/off 3 times in a row, that will reduce your Cell Standby battery usage (thanks to Phazeman for that).

It should only be necessary to do it once after flashing but if you think Cell Standby uses too much power at some stage you could toggle again the airplane mode

Usual, basic recommendations :

- The best advice ever is to always flash with 100% battery
- Avoid having too many widgets,
- Avoid using live wallpapers,
- Avoid using energy saving apps (they actually run non-stop in the background, hence they use battery),
- Set your screen time-out to an acceptable low value, like 30 seconds,
- Brightness: use a low value (between min and 25%) or tick auto-brightness,
- Try different modems (as they are responsible for networks and networks use a lot of power) in this guide (bykakado74)
- Buy a 10% higher capacity battery (1650mAh) made by Samsung for SGS devices (fits perfectly of course )
- Calibrate your battery.

Battery Calibration

(not needed if you flashed with 100% battery and let it deplete/recharge fully 2 or 3 times)

Sometimes the battery isn't being used to its full extent, or it shows wrong values. This is due to some wrong data stored in a file called batterystats.bin stored in /data/system. The steps below will show you how to stretch the battery use and delete the file in CWM (ClockWorkMod) in order to start with a full battery and fresh stats.

- Charge your battery full, bump charge to get the highest level possible ; note that it's not a big deal if it shows 97% when you unplug after bump-charging, more info in this article,
- Drain your battery to 0% until it shuts down by itself (without plugging the charger or connecting the phone to a pc),
- Wait 2 minutes and reboot the phone to ensure the battery is completely flat (it might reboot fully, half way, not at all, don't worry) until it dies again,
- Remove the battery and wait 2 minutes,
- Replace the battery and plug the charger without switching the phone on until it shows 100%,
- When phone shows 100%, boot in recovery (volume up + home + power) and go to > Advanced > Wipe Battery Stats > Confirm (move up/down using the volume keys),
- Reboot the phone and unplug the charger when the "battery full notification" comes (wait for the notification before you unplug the charger!!!!!),
- Now use your phone until the battery is flat again and charge full (no need to have it turned off, unless you it to charge faster). Repeat 2 or 3 times and your battery will be calibrated,
- Only wipe battery stats once, run a few cycles of full charge / discharge and after that just use your phone as normal (i.e. no need to deplete / charge fully anymore).

Some explanations

The battery calibration tutorial I offer has been elaborated after a lot of reading. By draining the battery flat (completely flat) your kernel somehow learns from that and charging full while off will teach your phone the full battery range available to your phone once you turn it on.

For example for some people the battery indicates 1% left and they can still play 1hr with it before it shuts-down by itself, that's because the phone didn't know the full range of the battery (I don't know why though)

So if they recharged their phone as soon as they reached 10 - 5% then they never used the full potential of their battery. This is where the battery calibration does its work, it will not purely increase the battery lifetime but show accurate percentage left. And it will become more accurate after a few cycles.

Instead of doing this calibration you could also keep charging your phone full and empty the battery fully each time and that would also calibrate your battery after time.

Anyway I repeat that the best thing to do is to Odin-flash with 100% battery and let the phone discharge fully at least once, then let it charge full. I reckon this is enough and painfree.

* People reading this should be aware that leaving the phone completely flat for a while can simply kill the battery (Li-ion batteries can't go below 3.5V or they stop functioning). I reckon a phone left completely discharged for 1 week **could** destroy the battery for good. But I also think that very few of us would live without their phone for too long

This hasn't happened again, so it seems it was a one off.

OTA and Samsung Account aren't running on my SGS, so battery usage isn't a problem for me. Getting a good 24 hours out of mine, that's with medium to heavy usage. Hell of an improvement compared to 2.2 JPY.

[vandit]

I just jinxed my SGS with that last post....damn thing just FC and re-booted itself again!!

[Northern-dj]

Oh another SGS with the force close this is what I was Getting welcome to the force close CLUB!!!!! Which is joined now with the Brown Trouser club.

Nice to see some one on here having the same problem as me, I had it reset and it loses the use of the bottom buttons 

I have read all that that guy wrote and that just one problem I can not believe Samsung would put such a bad rom out.

Vandit the fix is I'm afraid that it's back to JPY then were ever 

Flash JPK Or JPU First then Flash JPY you may have to do this twice to get rid of the bootloader

Strange how we have not heard from Vodafone on this as there version is the same, they normally pick up on battery drain as they did with 2.2.1 this is three times as bad
