Its official!!!! Read this!

Well its official... 2.3.4 DOES still have the android OS drain problem!
My phone had an issue with the usb port and had to be sent away for repair last week.
I picked my phone up on Monday (2 days ago) after it had been repaired and it had been upgraded whilst it was away from 2.2.1 JPY ( I flashed it back to stock JPY before sending it away ) to 2.3.4 JVQ.
I have read a lot of posts debating that the OS problem is due to custom kernels etc etc, but my phone is still at the moment completely stock with only a few apps installed.
It was ok for the first 2 days but i have taken it off charge this morning and the android OS was draining 47% battery!
I lost 12% battery in 2 hours.
So yes the android OS bug DOES still exist n 2.3.4 stock roms.

Figure of speech mate...

please look at definition of "OFFICIAL" in dictionary...

I've never had OS drain in 2.3.4

Mostly this bug is caused to an app that doesnt let your phone go to sleep. Deinstall some apps and watch your drain again

you should get a warning to make you think next time

As far as i'm concerned your talking out your arse!
Mine is completely stock JVQ updated through kies, with heavy use i can get a day out of it and with light use just over 2.

As far as im concerned YOUR talking out of YOUR arse.
Mine is completly stock JVQ flashed from the samsung repair center and i got android OS drain after 2 days of having the phone back with like 4 apps installed from the market.

poor you =) oh yeah and it is official !!!!

OMG...it's official! Whatever shall I do.

"Its official!!!! Read this!" Seriously? Do people even read the forum rules? It's actually about good practices, really...

Try putting your wifi to sleep when the screen is off
Oh and that is unofficial but works
and there is a section that tells you now what its doing
The only bug that is left is the Phone FC problem

Why not just go back to Froyo, it's not that much different from GB anyway?...

GB is like the Custom ROM version of Froyo.
I guess it comes down to speed vs battery life...

I've never had OS drain on 2.3.3 stock after clearing cache partition and dalvik cache. Need root to clear dalvik cache though. Battery life is great seems much better than tweaked 2.2.1.

Even if it's "official" I oppose all the opinions that Froyo was so much better for battery life:
I have been running every GB Stock ROM (with Voodoo or Hardcore Kernel) and the battery life with my 200+ apps is slightly better (after a workday with wifi on I still have 30-40% battery left with GB instead of runnning empty on Froyo). I had battery drain after flashing some of the stock rom versions, but I also used Titanium Backup to restore system settings so I blame this for the bad battery life.
Now - running on JVR with Hardcore K15i T10 - everything works great!
But, if you feel like going back to Froyo, do so and stop complaining about problems with GB you most certainly triggered yourself....
BTW, even if if this is OT, could you please use more specific thread titles and stop insulting yourselves?

News on ICS bugfixes?

Any News from Google about the ICS bugfixes? I want to upgrade to ICS again, but until that horrible battery drain isn't fixed I won't.

Curious
Im curious too, gimme your ICS!!!

yeah i upgraded and although i didnt mind at first... this battery drain is really really annoying.

Is it really that bad?

I have no battery drain maybe wipe all and install ics from scratch

Though the Android OS kept awake for a loooong time,
the battery does not drain so much

As I've posted in the other battery thread, I'm definitely seeing worse battery life running ICS. It's about 10% less than what I'm used to seeing by the end of the day, while maintaining about the same usage.

So, no one knows anything?

I'm at 10hrs with 31% battery left. As someone else wrote its about 10% more than normal at this time of the day for me. So not horrible but some improvement would be nice, its not enough for me to go back to GB. NS4G

Google hasn't announced anything so no one knows. I'm pretty sure most employees do not return to work until next Monday, so I wouldn't expect anything new for at least a week or two.

I'm pretty sure that this bug will be fixed right away
Sent from my Nexus S using XDA App

I had the same issue in the beginning, but not any more after a hard reset with G+ & location services disabled. Actually, the battery performance is awesome.
Sent from my Nexus S using XDA App

I'm also assuming since this is 4.0.3, it already addressed bugs that were in .1 and .2 builds. I wouldn't expect a .4 anytime too soon.
But hopefully better battery life is among the improvements.

Myself
I had no problem with battery drain myself, but a really annoying bug - music was stopping itself withing 1-10 minutes after I`d started it. Wipe didn`t help. Sh*t!

So I guess all we can do is wait.

Try it yourself, charge your phone and before taking it off the charger you will still have thae last cycle details and graph in usage..
And if you look at the screenshot, it clearly says "Battery used by the display and backlight" .....

How do you get your Android OS to be so low. My note is always around 25% to 30%. Do you think I have something running that's draining my battery? I do know that I'm not getting anywhere near the battery life you guys are saying you are getting.

he could have disabled all animations, force-closed processes, etc.
I have bluetooth running eight hours a day, streaming music for four to five of those to it, at least three to four hours of reading massive PDFs (textbooks), ppts, and word documents, WIFI on whenever available, etc.
I've gotten 10-13 hours without too many issues. The 10 was with a LOT of screen time, wifi or data running always, and bluetooth running always.
It also depends how you charge your battery. I make sure to fully charge my battery, and then run it into the GROUND (eg note powers off completely) before I plug it back in. Every time. You get maximum capacity that way, there's a name for this, but I can't remember what.
Anyway, battery 101. Kill processes, disable unneccesary services, use WIFI when you have it, disable everything you don't need, disable sync if you want/need to, disable gps, animations, and especially use minimal screentime. I don't see why the note wouldn't pull at least 36 hours if it was left in airplane mode the whole time.

Actually I was just watching movies and listening through bluetooth, thats why I don't have other processes eating my battery but I didn't do anything special..just straight 6 hours of watching movies using mobo player..
But I noticed that using mobile data to surf the net would drain my battery faster, so try to use wifi whenever available..
Everything about my setup is stock, only de-odexed to manually install my language..
Also noticed that when my phone left idleing, there will be Android OS drain in my battery usage, wigh "suspend" and "events0" showing in BetterBatteryStats but I still didn't figure out how to solve that..

Dear ics users!

I've been pondering over whether or not to upgrade to ICS now as the german version is released. My question is whether or not the battery life is similar to what you get with gingerbread. I've attached an image of what i get on a normal day, when i am at work and use my phone normally and not when i am sitting at home and never let my phone hit deep sleep!
Sure you get a lot of added features but battery life is what i really care about at i need to go sometimes two days without charge.

Got around 74 pct after 9 hrs of extreme light usage.
Sent from my GT-N7000 using XDA

How does it compare to ICS hour by hour? any difference would you say?

I would skip this Samsung release of ICS. Samsung's interpretation of ICS is not terribly different then GB unless you run a different launcher. I thought battery life was worse on the German release. With the added risk of bricking a few have experienced, don't do it.
If you want try the ICS, go with this one;
http://forum.xda-developers.com/showthread.php?t=1627854
With this one, you can easily and safely role back to GB from a nandroid backup. This one does not have Touchwiz and the SPen is not fully functional as it is in TW.

I find battery better on GB personally but not by much when u compare it to the silky smooth quickness of ICS

It's a shame because i really wanted to put ICS on but if my battery is going to die out in a day, will be pointless to have. Thanks for the advice people!

I'm getting about the same, maybe slightly better its hard to judge, yup never use your phone the same each day

For me so far samsungs 's ICS has not even been close to the battery life I got on Stunner. I'm a little disappointed but not enough to go back to ASOP or GB. Oddly enough I love TW with ICS Elements fused in.

It looks like it drops pretty quickly even when your screen isn't on. Are you sure you don't have wakelock problems? I think your battery life could be better, even without ICS.

Well i've just downloaded the app, xda edition ofcourse, lets what happens but judging from my deep sleep time, doesn't seem like i have a wakelock issue.
Any settings i need to change in the application or leave it to run its magic?

My battery life is noticably worse in ICS. I'm getting a lot of odd wakelocks that I never saw in GB.

This is my phone . You decide.

Well, if wakelocks aren't the problem.. Then I don't know.. ICS battery life seems better in general, but GB shouldn't be that different (and wasn't for me me I used it). Not that your battery life is bad or anything, but it could be better. Like I said, your phone in deep sleep should hardly use battery at all.

Well looks like I will have to test it out and see the outcome, looks like I shouldn't get my hopes up.
