I've been debating whether or not to upgrade my firmware to the latest and I keep going back and forth.
Can we discuss the pros/cons of doing so?
All I really know is that NOT having the new firmware limits support for most ROMS and can cause some issues. I have also heard its hard (impossible?) to go back to the old one if it was necessary to do so?
Thanks!

Pros:
ICS is awesome!
Smoother, faster, etc
Battery seems to charge sightly faster
Cons:
Bad battery life (horrible, worse than GB)
CPU overheats (sometimes to 110 degrees!)
Worse reception
Can't downgrade to old firmware till we get S-OFF
In other words, don't upgrade!
I personally have stayed off the firmware and I'm going to wait until ROMs are based off the official OTA or we get S-OFF.
There's a firmware patch anyway that lets you run recent ROMs on the old firmware, so that's a plus.
I've been running ICS ROMs for months with no issues and it's actual ICS.
Heard too many issues coming off the leak anyway.
It seems like the new firmware has the CPU running full tilt where the old firmware did a better job of governing. So the phone gets hot quick(for me screen on only) but stop using it and it cools off fast as well.

I thought the CPU issues were with the kernel, not the firmware?
For me, the news has all been good except for one thing re: new firmware...
Cell Reception.
I can't keep a call connected unless I go outside. Data is great, and overall signal quality is good... until I get a phone call. Then I immediately lose at least 2 bars! How dumb is that!?!?
I can't wait to get S-Off so I can flash the old radio back on. I'm hoping that fixes it.
Pro : no more Blue Flicker
Cons : Reboot like a zillion time a day WTF ??? Bur I think it's just me
Glad I posted this before just going for it. Seems like its not worth it at this point in time. S-off is a long was away, right? I'll just stick it out with the old one.

It would seem we're not as far off from it as we once were
but you're a lot better off without the new firmware IMO.

I do too, but I think it's more due to the Devs like Nils and lllboredlll tweaking their ROMS for max battery conservation than the new firmware.
I've just solved my rebooting Issue by doing this
1. Reboot into recovery -> Format all to EXT3 and wipe everything
2. Lock Bootloader
3. Flash the leak -> let it run till the end and will automatically reboot back into bootloader.
4. You'll notice the "TAMPERED" on top of the screen has been gone.
5. Flash the leak the 2nd Time and you'll be good.
I've been on it for 3 days without a reboot or slow down or heating issue. Now, I gotta say this leak is great in term of stability, battery life, signal (in Seattle,WA) and performance compared to Gingerbreak.
First, here's a poll on battery life. It seems most people got better or the same battery life with the update.
http://forum.xda-developers.com/showthread.php?p=23874951
I upgrade to the new firmware and at first thought I was getting horrible battery life, then it got better about 8 hours with 2 hours screen on time.
Then, I decided to go back down to the old firmware and radio because Andy told me he was getting better battery life on it. I went back down, a and honestly--I haven't noticed a real big difference in battery life with screen on. Both firmwares get about 2 hours on screen time. You can get awesome battery life on either ROM If you leave screen off, but that kind of defeats the whole purpose of using the phone. The new firmware gets better battery life when the screen is off, I think.
The radios are hit or miss, I think. The 4g reception is always different day to day in my daily commutes. Sometimes I'll get a constant 4g signal. Other days it'll be spotty, while some days it just stay on 3g and then I have to put it in airplane mode to get 4g again. And then 5 minutes later it goes back to 3g. I haven't really noticed much of a difference in call quality, but don't really pay attention to that.
I may go back to the new RUU, honestly.

I guess what confused me was something in this thread led me to believe that if you used the "patch" to install from GB, you would still be on the old firmware but running ICS. I'm currently on ClearnROM ICS Pro (ICS obviously)
The very first thing I did upon getting S-OFF was to get off that darned leaked firmware.
I sugesst waiting, personally.
there's so much more negatives than positive, at least was for me.
I run ICS on GB firmware and runs great. Sense 4, does as well. the patch works very well.
also before returning to GB frimware, I was running the leaked for a while and I personally didn't notice the new firmware to be much if any smoother.
all it did was overheat and destroy my batt life.
lesson learned for me.
no more messing around until we have an option to return to normal.
I am just lucky that I didn't brick my rez in the beta s-off(which the method works great BTW!, I hope to see it released ASAP!!) and was able to return to stock firmware, and enjoy my phone again.

Just so we all know, what all did it take for you to roll back to the GB firmware when you had S-Off?

How well is the radio working with older RUU? Also, how is the battery life?
Haven't really had a chance to test it. I installed SetCPU to make profiles when the screen is off and etc. Hopefully by tomorrow I will know how it goes. I only made it 8hrs on the "Out of the Box" config. So hopefully this puts a few more hours on to it.
any idea how high we can over clock?
Stock Kernel you cannot overclock
how much space do you have availible once bloatware is removed?
honestly I haven't personally deleted much of anything, as I am afraid that like other Verizon phones. I may delete a key app, that will disable the phone. Until I get a proper recovery going I have to say, you will need to find someone with more balls that I.
I suppose I could go re-flash the custom RUU that was made for rooting to get it booting again, as I have saved many people's non booting phones that way. However that would require more time than I care to waste, since I have alot of work related info I just got restored on the phone.
i sucked down 50% battery in 6 hours, not really using it much more than a few texts... and i have the LTE radio turned off in the service menu.
and, on the RUU with r/w system the phone was choppy / slow.
that sounds like my stock TB, but I use it a lot

Looks like I will wait til we can root the current firmware
LTE on the older RUU used for root is horrible.. Compared to my buddies stock TB, he's pulling over 15 meg down.. I couldn't get more than 3 ever..
Flashed back to stock and now my speeds line up exactly with his.
I am getting 14Mbps with Wireless Tether right now! Not too bad.. haven't noticed any difference with the older rooted firmware... keeping this until CM7 for TB!
HI ,

i dont quite understand the ppl who buys android phones and doesnt modify it... i mean the only TRUE difference between iphone and sgs2 is powered by iphone iOS and Android.. which is open source... the other difference doesnt really matter much.. processor ( yea its more powerful but duuh.. there isnt much things to do that really require that much power) or the screen (duuh iphone has abit better screen so what? if u dont look closely u wont even see difference(atleast not me)) so yea if you gona buy sgs2 i RECOMMEND you to do alot of flashing and rooting and play with it around
WITH BACKUP of course... especially the EFS backup
It all depend how you use your phone. Sometimes I it for hours on end and go through 2-3 batteries a day (I have 3 spares).
Today I used it very little. About 7 phone calls, 2 messages and only about half an hour browsing / xda etc. Currently on 85% after 18 hours.
So usage makes a massive difference.

do you think is there a need to change the Kernel version ? or just do the official update and it will be fine ?
Definitely stick to official updates. Regardless of what anyone might tell you, it's a fantastic phone running stock firmware. And if you're not confident about flashing custom roms/kernels (there's a small risk everytime you do it that things might go wrong/you might brick your phone), definitely stick to official firmware.
At the very least until you've done a lot of reading on here and are confident to try different roms/kernels. If things do go wrong, it might take you a few days of research on here to work out how to fix your phone (which means you won't have your phone working for that time), and at worst you'll have to return it to Samsung for repair. Which you'll probably end up paying for as running custom roms/kernels voids your warranty.
So slow and steady, stick with stock for a while and read. Then read some more. And when you're done doing that, read for another couple of months.

Sorry but got to disagree, yes its a great phone as stock but with custom ROM and kernels its an amazing phone. The devs here have done some amazing work. BUT (and its a big one) dont do a thing till you've researched your arse off, and you understand all the risks of what your doing.

(woohoo 400th post)
Latest stocks have been fine, even stock kernels have shown improved battery life. But with a custom rom/kernel combination your setting up a phone the way you like it with many ways of tweaking it.
If you do buy one, update to latest stock, try it out, if your not happy then root and enjoy.
My post was an attempt to persuade the OP to stick to stock should he purchase an SGS2. The last thing we need on here is yet another " Hlap mai fone broked !" post :-/ (and everything that goes with it).

My wifi and GPS are on 100% of the time. I never turn them off. Today, 23 hours since charge and about 2 hours screen time and battery on 69%. But 3g is off (2g only) and no email sync.
Yesterday, heavy usage and went through at least 2 batteries.
BTW, since I got the s2 I've only ever used cf root kernals. Nice and stable for me and the closest thing to stock. Others claim increased performance or have over clocking etc don't interest me. I believe the phone doesn't need them. Also using Checkrom. On the S1, well that was different.

I'm S-Off and RUU'd back to GB because the new firmware/radios had me down about battery life. Before the leak, I used to get ~10hrs total battery time with normal usage on stock battery. Once I went to ICS Leak, that was down around 6 so I figured I'd go back. After a few days being back on GB, I've found I still can't get my battery to last. I'm running Ineff. 1.4 and Incredikernal 6 currently, and When my screen is on (brightness set at 20%) for 10min I'll drop 15%. Anyone have words of advice? I'm seeing people with ridiculous battery life and wondering if I should run the GB RUU again. Thoughts? Also battery still burning upwards of 118 when screen is on for a little bit.
The latest ICS kernel was the biggest issue with battery life...
What settings do you have on the kernel?
I'm just letting it run, no Set CPU settings or anything. Should I not let it govern itself?

The first thing I did with s-off was downgrade to the latest GB RUU from the ICS leak. Now I'm on eng hboot and CleanRom 4.3 Pro with the GB patch and stock kernel that's packaged with the ROM. This was all yesterday. Today I've got 41% battery left after 16 hours (extended bat.) and have used the phone considerably setting up the ROM and reloading all my apps, plus several phone calls, emails and texts. I don't have 4G in my area so that's turned off and I know that 4G is a significant drain but this is noticeably better than what I was getting. I'll have a better idea in a couple of days when everything settles in.
I definitely would run the stock kernel for your testing purposes with no CPU control. If you still have major issues I'd look towards an app or location service that's enabled.

I unlocked bootloader and tried updating to the ics firmware and trying an ics rom but still has the same issue. I performed the s-off wire trick and rolled everything back to stock firmware and rom and that didn't work. never messed with a custom kernel. Anyone have any ideas for a fix? Or are we just going to have to wait for an official update from verizon? I've read of people on the verizon forums complaining about wake lock as well.

Ive noticed worse battery life as well after going s-off. Thought i was going crazy.
There are definitely degrees of badness here.
GB on GB firmware/radios is the coolest.
GB on ICS firmware is warmer.
ICS on GB firmware is even warmer.
ICS on ICS firmware is the hottest I've seen.
I cannot run screen-on indefinitely on any ICS without overheating the battery.
I had the same problem it appear suddenly
Cell standby took near as half screen does
I did try many rom
Only full wipe helped including internal strong
Now I'm with inf1.4
Battery is the gr8est
On the wake lock issue, someone discovered the AOSP lockscreen was preventing the phone from sleeping correctly. I can't remember if it was a certain combination or just the lockscreen running a background process.
Since you've tried all kinds of stuff I don't know if that applies to you or not but if nothing else I was hoping it might spur a thought process or new ideas for research.

Anyone who updated your SGH-I777 to ICS facing heating issues while downloading stuff from market or using internet over WIFI/DATA?
My phone has horrible heating issues after the upgrade from 2.3.6 to 4.0.3. Its terrible. My phone on GB was smooth like butter and never faced any kind of heating or lagging issues. but this ICS upgrade is just one ****.....
Please help me by sharing your experience while on WIFI or DATA connection.....
Mine has been doing that for a few months now. Since I started using AOKP. Anytime I use my phone for a few minutes it starts to get warm, getting hotter the longer I use it. I was worried at first, but got used to it. Like the camera whirring noise, I just ignore it mostly.
I am planning on getting a warranty replacement anyway sometime before the warranty runs out, so I haven't worried about it.
It could be a rouge app running all the time. Better Battery Stats will let you see if any apps are preventing your phone from sleeping. CPU spy will also let you see if your phone is sleeping. A rogue app generally causes battery drain too. I see the same battery life on ICS as GB for the most part.
Sent from my SGH-I777 using xda app-developers app
I don't think it has anything to do with the app running...... Its a very fresh installation and after the boot, I have tested downloading the say 5 apps from Playstore.The top portion of the device heats up big time. I am an android engineer and have rooted and applied custom roms on the devices but I am not willing to do that on this device becoz the Stock GB on SGH-I777 (2.3.6) is the best i have come across in terms of stability and efficiency. So just badly wanna go back to stock 2.3.6 but online I saw ppl facing problem when they downgraded to stock 2.3.4.....
I am still repenting on upgrading the device...uffff damn it
The only time I noticed anything like that was when I put my phone in the
mobile dock and using the GPS and it was a hot day plus it was charging.
Once I plugged into the regular house charger it cooled down
(even though it was still charging).
I guess they have overlocked the device and thats the reason y its heating up
I don't over clock my phone. I run AOKP with Fluxxi kernel, and don't touch the CPU speed, voltage, or governor settings. My phone didn't get hot like this on SHOstock, but pretty consistently on AOKP it heats up when ever I use it. I posted in another thread about heat issues that at the end of the day I had 13 hours up time, and less than 3% was at 800 MHz or above. The most common was deep sleep, 200, and 500.
I don't worry about the heat anymore, I got used to it. Most of the time its just warm, but if I get downloading a big file it gets really hot. It doesn't seem to affect the performance or battery life, so I don't worry.

I would love to go back to GB but scared use the ROMS that are available online.. I have done lot unlocking and rooting stuff on devices but i failed one time and thats what is holding from rooting/unlocking the device. Also I have realized that the custom ROMs are always buggy.....
Some people have had heating issues on ICS, and others not. Don't really know what the difference is. I suppose there could be some differences in the hardware.
Anyway, going back to gingerbread is relatively safe. You can go back to fully stock, or you can go back to stock plus root. Each of these options would be by flashing the firmware with Odin from a windows pc. Neither of these packages contain bootloaders, so the risk is minimal, almost non-existant. The packages are UCKH7, Gingerbread 2.3.4, although there is a UCKK6 plus root available also. You can use the guides linked in my signature, the one for returning your phone to the store for straight stock, and the one for flashing firmware without incrementing the flash counter for stock plus root.
Custom roms vary in stability. Some are extremely stable. I would say that SHOstock2 is as stable as about any rom I have ever used. It's certainly good enough for every day use. It is ICS though, and don't know how your phone would do with it. I have seen a few reports of overheating with it, although my phone rarely gets even warm to the touch.
Just wanted to echo 1) my phone also gets hot when being used heavily (wifi, bt, gps, data, sync, all on) but not to the point of concern. And 2) the reco of shostock2 3.1.0+ for stability.

One of the most stable, smooth GB roms is UnNamed 2.2.1, which you can check out HERE. I used it for a good while, but wanted to try ICS. Excellent, stable rom, with themes available.
...its called fried ice cream.

Some people have had heating issues on ICS, and others not. Don't really know what the difference is. I suppose there could be some differences in the hardware.
Anyway, going back to gingerbread is relatively safe. You can go back to fully stock, or you can go back to stock plus root. Each of these options would be by flashing the firmware with Odin from a windows pc. Neither of these packages contain bootloaders, so the risk is minimal, almost non-existant. The packages are UCKH7, Gingerbread 2.3.4, although there is a UCKK6 plus root available also. You can use the guides linked in my signature, the one for returning your phone to the store for straight stock, and the one for flashing firmware without incrementing the flash counter for stock plus root.

I did try your odin but unfortunately it didn't recognize my device at all. So I juts gave up on using your odin. I am not sure why odin is not detecting my phone. I am using SGH-I777 AT&T with ICS 4.0.3. Any idea whats the problem. Please note that I have not rooted this device and its always been on stock firmware/software.....
i m on AOKP rom with my i777, it does heat up a little bit (lcd top part and back near camera) when i m using 3g, wifi is ok..i wonder if the antenna is around there so its causing heat?

You got it right. Thats exactly where I feel the heat on my device..... Trust me, I didn't feel any heating effect whatsoever when my device was on GB. So I m pretty sure that the hardware is all good and its the firmware/software thats screwing up the device.
Personally I found my phone got hot after setting up an exchange account on it. I also got massively reduced battery performance. Once I removed the exchange account operation returned to normal.
One or more of the apps (from the old GB install) that is running in the background causing it to heat up, I was ruuning into that issue when I first updated to ICS. I end up doing the factory wipe and reload every apps back on. Now I don't have that problem.
Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

Can't find "media scanner fix" in the market. Any chance of a link.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
