Hi all,
Many of you have upgraded your firmware thru leaked versions posted elsewhere on this forum. My question is to all those who have used the leaked versions. What are the points of difference between the performance of these three versions : KF3, KG1 & KG2. If I understand correctly, only KG1 has Android 2.3.4 out of these three versions. So if you can share your experience about whether there is a change in Battery life, smoothness of operation, other visual changes etc.
We, in India, are still on KF3 officially and still waiting for the KG2 upgrade via Kies. But I'm using KF3 currently and Battery life has improved considerably over KE8 in the current version. Is it worth upgrading to KG2 via the leaked firmware or should I wait for the official update from Kies?
I'm on the leaked KG2 2.3.4 with a custom ROM.
I must say, battery life is amazing. I can go through a day of heavy use leaving home at 7am and getting home at 7pm with 40% or higher battery life remaining.
Mind you, this is heavy use from watching netflix (movies), browsing the web, texting, phone calls, and playing games all while the 3G is running in the background with gps location, email syncing ans google sync.
So far, I'm loving KG2 2.3.4.
I was running KG1 2.3.4 for about a week before flashing KG2.
Sent from my GT-I9100 using XDA Premium App
KG2 modem does have a stronger WiFi signal .
jje
I havent had any real battery problems since I swapped to a custom rom and nuked all the bloatware.
2.3.4 has its advantages like video in gtalk and the androidOS bug is all but gone (for me anyhow)
As far as wifi, I never had any problems with it, maybe it didnt show that many bars, but it didnt seem to have any problems even on 1 wifi bar
Looks like KG2 is an improvement over the previous firmware. I am tempted to switch to KG2 immediately going by your encouraging feedback. Will wait for a few more days for the official Kies release to come.....if it doesn't, then I'm also gonna flash the KG2

CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.zip This is the latest root kernel posted by CF. Does this have android 2.3.4 or 2.3.3?

It is 2.3.4.
Thank you, Octavius69, for confirming.
KG3 has the best battery life ever. Today I watched movies, played games, I had screen on time of 3.5 hours, and battery was at 55%. That means if I kept on, I'd get around 7 hours of screen time. A big improvement over KG2, even though the Android OS bug is still there.
Is anyone else having a problem with their wifi being connected and not working?
Ever since i flashed KG2 with the one Darkyy released ( Thanks by the Darkyy) everything has work perfectly and battery life is great. The only thing is the wifi and it seems to happen after it's been connected for awhile and when i wake the phone to browse say the market, it doesn't have a signal even tho 2 bars are showing, so i reconnect and it works again. It only happens now and then and i think there could be an issue with the mobile network as a couple have calls have gone to voicemail even tho i'm sure i had a signal.

Did you flashed stock kernel? It's a known prob that stock kernel could break wifi.
Just got my GS2 and having HORRIBLE battery life. It's locked with 2.3.3 KG2, so I'm wondering if it's a defect or if it's the build, in which case I'll get 2.3.4.
Other than the battery issues, I love the phone, but I already miss my Nexus One just a little...

Has any one tried to Update to AOS 2.3.4 on a "Non-rooted" Bell Mobile Phone?
Or can it be done after it is rooted?
I just got one and it dose suck the battery down fast... Hopping this will help. Because I heard that 2.3.3 has a battery drain problem, and also doesn't have Google Video Talk.
I have a feeling it will be a long time before we see a Bell supported update seeing as I don't think they will like the added Google Talk App seeing as they have a "pay $5 a month for unlimited video chat" feature, and will want people to pay for that...
If by update you mean installing one of the 2.3.4 roms from the dev section then all you need to flash a kernel with cwm, then go into recovery and install the rom.
Thanks for reply. I assume your answer requires the phone to be rooted? Witch was my second question. First I would like to see if it can be done with out rooting...
there is no official 2.3.4 out yet just leaks. So yes you have to be rooted.
Thanks, looks like I'll have to wait till there is a good root walk though for bell mobil phones to come out before i get started.
Thanks again.

The walk through posted above is quite easy. Literally had myself rooted and running in under 15 minutes after purchasing the phone, and getting back to my office.
What AOS did you end up using? Our can you keep using the same one, only with root? and if you can keep the same AOS, can you update it to 2.3.4 now?
I too am interested in a working 2.3.4 for a rooted bell SGS2. I've read somewhere that a guy did it but lost 3g conectivity
Currently running Cognition 1.31, just flashed the CWM/root using Odin... then nandroid backed up the Original OS (with root, we're stuck until a proper version of the original is released) wiped it, and installed via zip... no fuss, no muss, no loss of radio... However, stock, or updated kernel/radio... my HTC Sensation gets double the speed on the network... I usually hover arough 6-7Mbps on the sensation, and I've yet to break 4Mbps on the Galaxy
Actually, the two of you can help me lol
I did things so fast I didnt write anything down
can you go into the dialer, and type *#1234# and give me the numbers?

You don't need root, you go into download mode, flash the kernel then go directly into recovery mode and install the zip file. All roms from the dev section are rooted.

Would that 2.3.4 work after I rooted CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4?
Has your battery life gotten any better?
The battery life on this phone i crap! I got a my wife an iphone 4 at the same time i got this and she plays games on it for hours and only uses like 10% of her battery. If i did that it would use at least 50% of my battery 2.3.3 needs to go!
Yeah the battery life could be better. I downloaded these widgets for wifi on/off autosync on/off 3g on/off and they help quite a bit when I'm at work and I don't have time for facebook chat and all that nonsence. Besides the wifi at my work is garbage so the phone breaks a sweat connecting and reconnecting for 8 hours =/
My phone's been on for 11 hours and i'm at 85% battery after sending like 12 texts checking facebook 2 or 3 times and 2 phone calls. Those widgets really help. Autosync and wifi really drain this thing.
I just bought a Bell S2 (had a Euro version before) and I have noticed that the following apps are big culprits in battery drainage.
If you are rooted, install Titanium back up and do the following
Wifi Sharing (freeze this app using Titanium)
Wifi Sharing Manager (freeze this app)
Social Hub, there are two processes (freeze both)
IMEI Tracker (freeze)
GPS Navigation from Bell (uninstall using Titanium)
I'll report back. When I did this for my Euro version it gained me about 5 hours of battery life.

there is no battery problem it depends on ur usage.
turn off samsung apps under settings
turn off fast dormancy *#9900#
freeze wifi sharing apps via titanium backup
under power saving menu choose to go into powersaving mode when battery reaches 50%
in ur email accounts choose to sync manually. in social hub, when u click on an account it it will sync
in gmail account choose to only sync priority inbox
only use Automatic brightness when u r outside. inside the house keep it to minimum
if u dont use wifi turn it off
turn off gps
turn off bluetooth
dont use too many widges ( i only have circle battery and active applications widget running in my launcher.
if u do all above u will get 2 days of normal usage,
If I need to turn off a bunch of things or gimp my phone to get a longer battery life then why did I buy this High end phone again? My wife (and be because I don't want to know) knows nothing about her iPhone all we know is the battery lasts about 3x longer them my phone and we bought them at the same time and the Iphone is like a year+ older... That to me means there is a bug or Samsung messed up. I'm going to go with a bug...
You think they would ever release a car that is the same class with better radio and gadgets it in but it takes x3 more gas then the other brands car from a year ago... NO.
With all that said I have had my phone over a week now and it seems my batter is lasting longer, Quite longer..
Hi everybody !
Let's make a poll about the huge question of the moment :
Are you really experiencing better battery life in Gingerbread 2.3.5 over 2.3.4
Please vote above !
And please try to report only after doing a properly battery calibration and at least 2 intensive days (or normal) using !
Yes, I clearly see a difference !
With the stock rooted KI3 (CF-Root), that's important because with any other kernel i have worse battery life than kh3
I always have a intensive use of the phone, and in last 2 days after i flashed the KI3 (keeping the stock kernel) i play double time, same phone calls time, same number of sms sent and i finish my day with still a bit of battery left.
On KH3 i had to plug my phone charging during the daytime.
Totally different opinion comparing to th guy above me. KI3 for me is not better then KH3 which I used before
Sent from my GT-I9100 using XDA App
Definitely better than any before.
Sent from my GT-I9100 using XDA App
Night and day difference for me. Instead of having only 25%-30% left at the end of the day I have 40% and above now... that's after about 22 hours off the charger.

I think exactly the same actually, but I prefer to not vote on my own poll right now because I just migrated on 2.3.5 since yesterday only, but at first impression I was more pleased on KH3 (2.3.4), or maybe it's same for me. Waiting to test few days more to really put any judgement.
Still waiting for a nice AOSP theme for it before i switch i think

Hi Intratech.
Would be very interesting if you could share how your phone is configured (3G, Background Data, Auto Sync etc), which kernel you use, tweakings and so on.
Thanks.
Regards.

Exactly. With KH3 (which was significantly worse than KF2), I would barely have any juice at the end of the day (ran out a few times in fact). KI3, I easily still have 40%+... there is a HUGE difference.
Thank you Samsung!

I'm using the Frankenstein build. My emails are set to sync every hour, Gmail gets pushed to the device. SNS stuff is set to sync every 3 hours as I manually check stuff inbetween and it gets updated anyway. Data connection always on, background data is allowed. I'm using the stock kernel. The scheduler is set to on demand. No task killer is used.
I haven't actually had the time to do any tweaks to his firmware to make it my own setup as yet so it's pretty much vanilla apart from the stuff that's been frozen: Games and Music hubs, AccuWeather ( I use Beautiful Widgets instead), AP Mobile, Buddies now, days, Digital Clock, Dual clock, WiFi sharing and WiFi sharing manager and Yahoo finance.

Well, apart from the kernel (I'm using Ninphetamine 2.0.5), the rest is almost the same, with the exception of Bluetooth and WiFi Sharing (all freezed), and several Samsung addons uninstalled (music/reader hub, tasks, diary, buddies, live wallpapers etc).
Unfortunately I can't get more than 16 hours, which is insufficient to me. Yesterday I flashed only the original modem.bin of my carrier. Let's see if this provides some different scenario.
Thanks one more time.
Regards.
Using Better Battery Stats, I find my Awake time is always the same as my wifi on time.. and much much higher than my screen on time.. I'm baffled right now.. apart from that.. KI3 does seem great to me.. but my battery is in pain.
2.3.5 is the best so far for me buddy. switched to Foxhoud by BatistaRom and so far 3 hours and only 5% battery drain....hope that answers your question

That is the same thing just a no-wipe version and maybe a little modify. I always used firmwares from samfirmware and since the last firmware i think it was ki2 i had a good battery life. 4d8h max i had and with some use. This one now i have 2d8h and 32% of battery left. So i can't be if i didn't use Intratech's Frankenstein package
My battery life has also improved with 2.3.5. I'm running Leomar75's revolution ROM v2.7.1 with siyah kernel.

Ninphetamine is a fantastic kernel, but that's why you have drain.
Old kernels are not optimized for the 2.3.5
Try the stock rooted (CF-root) or the siya one.
You can always go back to ninphetamine when a 2.3.5 optimized version is released.
On the 2.3.5 the stock one is faster than the ninphetamine (3800-4100 quadrant score all the time) and battery last really a lot longer.
Also the phone under stress is a lot less hot.
Just my 5 cents i think its worth a try for you so you can check if it is better.
Again, im sorry for my poor english.

i actually beg to differ. im using batista rom based on 2.3.5 and using Ninphetamine 2.0.5 and so far 6h and 35 m and only 7% battery drain. and thats with wifi on all the time and browsing here and there. so far so good for me i say..but its always down to personal preference what kernel suits your needs i say..Different handsets kernels work differently

Ye, i think at the end the best choice is to try and see wich one best fits your personal desire. Also a kernel can act different on a S2 than another S2.
I always suggest based on my experience, but ofc can be totally different for someone else.

Hello, yesterday i have flashed a KI3 firmware from intratech and CF-Rooted my unbranded Galaxy S2 (previously KF3 CF-ROOT) because it should be one of the best stock firmwares for the device.
Well... the WiFi is absolutely crap -- i can't get a full signal being in the same room of my router-- for instance now i am in a place where i previously had 3/4 of the signal and now the WiFi icon doesn't even show, the network signal is also worse.
No noticeable "smoothness" over previous version but now i have an annoying bug where i can see whatever i was doing before the lock screen pops up.
Battery is surprisingly lasting less (properly calibrated).
The benchmark scores are also worse (CF-Bench and Quadrant).
I have wiped cache, data and factory reset from recovery mode and the only thing i backed up was the WiFi passwords using Titanium. Battery saving is disabled.
Obviously this doesn't match with the hype seen around here about this fw, is there any special configuration required?
same is here 2.3.5 KI3 flashed a week ago and only bad changelogs:
Battery is lasting less and i have an anker 1900mah battery
Lag when i write a sms or open the messagebox.
QuadrantScores same or worst as the 2.3.4 -.-
KI3 is "outdated" now. I don't recall being wowed going from KH3 to KI3.
I found a great improvement from KI3 to XXKI4 (not to be confused with XWKI4).
That said, there have been newer leaked firmwares since the last time I was on a Samsung based ROM. Some may be better, some may be worse, some might just be the same.
im using KJ3 frankenstein and this is great i am using with speedmods kernal and so far today i have been going for 8h and with total screen on so far of 45mins and my battery is still at 85% not bad!! plus i have syncs for email and twitter on try kj3
Thanks, i will try KI4 or KJ3. Also thanks for not be retarded like the guy who edited the tags list.
Also, the OTG is disabled, does it works in any of theses FWs?

Im living in Germany and i need the german language does the xxki4 have the
germany language ?
And which improvements are between the ki3 and ki4
Flashed KI4 as mudferret said, and NOW we are talking
The WiFi reception is better and more stable than KI3 as far as i can tell, comparing with KF3 though i still need to check out in some other places.
I still have the homescreen appearing before the lock but is way less frequent than KI3.
Benchmarks going up, equal or better than KF3, 300 quadrant points better than KI3, CF-Bench also better
Waiting the battery calibration to post more impressions. But the initial impression is pretty awesome, rating, four out of five smiles:

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

But you have not given the battery time to recalibrate itself .

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?

Hi,
I got the OTA update to 4.0.4 a few days ago on my SGS2 (network O2).
Coincidentally I've been running with various launchers (Nova, Mii, ADW etc) but I decided to go back to TW. So I deinstalled them all at around the same time.
Anyway, since the update my phone has been playing up constantly. I've had random reboots whilst the phone has been in my pocket. I've had plenty of short and long freezes. The stock browser locks up quite regularly if I have many tabs open (or any one of them has many images). It also reports inability to connect to the proxy server (though I haven't got a proxy set up).
And to top it all off, my battery life seems to have gone back to being terrible (if I use the phone as a web browser for an hour or so can see 50% of the battery life go!) The battery usage indicates the screen and the internet are taking 75% and the OS only 6%, which is different from what I've seen before. The phone runs very hot sometimes - the screen can get too hot to hold my finger on.
So is this something anybody is seeing, or has my phone just freaked out? Is it worth a factory reset? Is it possible to force the 4.0.4 update to be re-applied? Anything else I can try?
Cheers,
Ross
I have observed the same after moving to 4.0.4. Especially stock browser likes crashing. Anyway, all crashes happen much often for me on ics than on gb.
When I've tried LPT I've noticed extrem battery consumption while using but no crashes.
My wifes phone had similar stuff Ross so we sent it back to Samsung.Was very hot around camera and was freezing a lot,and wireless hardly connected.
When it comes back Um sticking on GB like mines..

I experienced all of this you are saying. Tried a factory reset from stock cwm, but didnt solve anything. In this point I just downgraded to 4.0.3 and had the update to 4.0.4 LPT with kies. To my surprise, all things are good and stable.

Both my wife and i have i9100's
i updated to 4.0.4 through kies - no issues at all
she update to 4.0.4 via OTA - freezes, gets hot, kills battery
Both phones unlocked unbranded
How do i down grade to 4.0.3?

Flashing a 4.0.3 firmware trough odin
Thanks very much for all the replies :good:, it sounds like an Odin downgrade and then upgrade is the way to go, I'll try that tonight. And if that doesn't work I'll try using an older modem.
And if that fails, I'll go complain to O2.
Factory reset should solve that! I had similar problems after upgrade from GB to ICS, after FR all was right.

Never recommend factory reset to someone running stock 4.0.4 ROM on stock kernel
Swyped from my Samsung Galaxy SII
An update, in case anyone stumbles on this thread...
I chickened out of doing the Odin flash, as I googled for a 'how to' and saw it'd invalidate my warranty.
I'm aware there's a way to decrement the flash counter, but I'm a noob at this. I'll stay 'chicken' for moment.
So I did the easy thing... I ran my battery absolutely flat, then recharged the phone to 100%. It certainly seems better - maybe the battery state wasn't being detected properly and caused some issues?
Certainly I've stopped getting the overheating / rebooting / freezing / catastrophic battery life.
I'd be inclined to leave it as-is, but my battery life is still pretty poor compared to how it was... if I browse the internet for a short while (over wifi) I can see big chunks of my battery percentage disappearing.
So I'll go to the O2 store that's nearby, and see if the 'guru' can help me - either by okaying an Odin re-flash, or by sprinkling pixie dust on it or some such
I had another lock up and self-reboot, so I decided to take the plunge and re-flash it, which was relatively simple.
Fingers crossed it does the trick! But if it doesn't, well I can go back to 4.0.3 now.
