I read through all the threads about the new upgrades, but I have not seen anyone talk about power consumption and battery life.
Can someone who has done the upgrade lay out the differences?
It seems to have improved, but I've done quite a few hard resets and other various testing, so I can't say how much.. But it definitely seems to have improved..

About twice a week I have HELL days were the phone gets a work out and tomarrow is one of them.
The old Cingular ROM:
Turn on Phone at 6am-by 12 noon it would be dead, I use a lot of 3G and video streaming.
Tomarrow will be the first hell day since the new ROM, so I will report back tomarrow night and let you know how it goes.
After several days with the new ROM and a full day with the new 1.33 radio it appears that battery life is definitely improved.
I am running radio 1.27 and i can say that with this .rom battery has improved somewhat from what i saw in 1.20.....
The battery life is definitely better on the new ROMs. I'm running 1.27 Radio ROM and with a 3000mah battery my phone last around 10 hours now.
I certainly hope so. I would like to consider myself a power user. I have my push email downloading every 2 minutes. So I am usually dead by 3pm. I hope this will be better under those conditions.
Are people here using the battery saving hacks on the Wiki or are you using the default ROM settings? I have not checked, they might be the same in the new ROM.
I'm only using the default ROM settings.. Minus a few CABs in the extended ROM, but those are mostly things that annoy me anyway (like the Good Email and such)..

Has anyone tried the tweaks on the Wiki with this ROM? If so, how much battery asving do you get and what are the possible side effects?
bat life is so much better.... it would almost be dead by 10pm.. not its still over half by 10

I'm using Seraphim and I'm happy with the battery life. It seems to be worse than the GB ROM but I can get about 2% down every hour when the phone is idle.
I am thinking of trying different ROMs and battery life is very important to me. Which ROM will give the phone a better battery life based on your experience?
Thanks.

ah ok, im in search of a good ics battery friendly rom as well, actually downloading dag's ics "hybrid" rt now. i'll give it a go for the next couple days and post back. i was seeing about the same as you for seraphim.
In my experience, unless there's a bug, a ROM has little effect on battery life. Android is going to use a certain amount of power to run itself, and there is little that a dev can cook into a ROM to change this. Beyond the system, battery usage is from the screen, apps, and radios. If you are in an area with poor reception, and have lots of apps and widgets that frequently update in the background, this will decrease battery life.
I've used both DaGr8's Alpha II and Seraphim, and my battery drains less than 1% per hour when idling.
Guys a Search would have told you that Battery life is 99% on the user and has almost nothing to do with the rom. We could be running the exact same rom and get very different battery lifes due to the apps we use and how we have the device set up.
In the end there is not best rom. Only what works best for you.

Lately my battery usage in battery monitor widget has been going over 1000ma multiple times a day. In fact this has been the case both at the beginning of my Rezound's life on the first firmware, and again now.
At one time in between I used to never see it go over at most 700ma, and experienced reasonable battery life too. Usually I saw about 70ma to 300ma usage. This was with several different roms on the same firmware. I think it was the first or second ICS firmware but I don't remember for sure.
I'm starting to think the firmware a few versions ago was better on battery life. What do you guys think?
I was running GB with the old firmware up until just last week. I was averaging about 20 hours on a full charge with 1-2 hours of screen on time. The rom ran great and the only issue I really had was my 4G would cut out completely whenever I tried to play Youtube videos....
Last week I updated to the latest official ICS global rom with the new radios and firmware, and my battery life has gone in the toilet. I'm averaging about 15 hours on a full charge with the same 1-2 hours of screen on time. My phone gets MUCH hotter when just doing simple things like browsing the web, often getting above 100* F. On GB firmware I was usually in the mid 90's unless I was gaming. This is with the stock kernel. For the past couple days I've been trying FunkyKernel with some under clocking and undervolting which has helped the heat but not so much the battery life.
I'm kinda pissed and strongly considering finally going S-OFF just so I can roll back to the old firmware.
I actually think I had the best battery life on the first ics firmware, but like I said it might have been the second one. I don't remember how many there have been, but I have done all of them.
This latest one just seems to suck down power.
Anybody else have some input?
I just recently updated to the official global firmware and am running Rezone Redux with Funky 3.7. I'm not doing any undervolting and the only change I made to the frequencies was setting the min to 96 and the max to the stock 1512. With my extended battery, I'm averaging around 4.5 hours of screen on time, which is actually about 30 minutes more than I've ever gotten out of this battery. Then again, I keep my data, WiFi, and GPS off at all times unless they're needed, screen brightness at 13%, I'm using an app called Greenify to hibernate certain apps (not freeze, there's a difference), and I'm using the Wheatley governor. I'm very happy with this setup.

So maybe it isn't affecting your as much because you keep your radios turned off. I also use greenify and it has definitely helped.
I might go a day with my mobile data enabled all day and see what happens. I got into the habit it of toggling my data off about a year ago. The only reasons for me to keep it on would be weather updates and Facebook notifications, neither of which is really important enough to me to have them refresh automatically. I don't use push email or anything like that, either. I suppose it would make a difference for someone who needed instant email notifications and such.
Sent from my ADR6425LVW using xda app-developers app
I also keep data off most of the time unless the phone is plugged in, but still, battery just hasn't been the same since the latest firmware update...
I want to update you guys on my battery issue I thought was related to the new firmware. Every rom I had used since the newest firmware release was horrible on battery life. Using battery monitor widget to monitor power usage, I was often seeing over 1000ma usage many times per day.
I recently installed neo's infection 2.9.1 which uses a stock kernel based off Flahalf's work. My extreme battery drain is gone! The highest usage I have seen in 2 days is around 500ma, and normally it is 100ma or less! Not only that but this Rom is smokin fast. It feels like a new phone!
And it fixed wireless tethering! I'm so happy and thankful for the awesome work or devs have been doing. Thanks guys!
Unfortunately for peeps like me who enjoy gaming on their phone, the JB roms aren't all that great. Graphics performance is generally poor....
Maybe you should give it another try. I just played some shadow gun and the performance was fine.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

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.

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
Am I the only one? I just updated 3 days ago with RUU to the latest build. Before the update a full charge would last me about a day and a half with moderate use. Now with the new update I am lucky to last half a day without it going into Power Saving Mode, then about 2 hours later it will be in Extreme Power Saving Mode. Anyone else getting sh!tty battery life since the update?...

Battery life is incredibly complex and elusive. Asking if other experience the same is all but useless. Reason being, such comparisons are just anecdotal and will often not apply to you. There are simply too many variables, such as how you use your phone, what apps, and often most important is reception in your local area. It could be that the new radio deployed with 1.58 simply does not play well in your area. The intent is to always be "improving" the radio software, but its the minority of cases where it actually gets worse, which can greatly affect battery life.
Also, I've seen a lot of cases where AT&T bloatware runs out of control and kills the battery. You might start by looking into this. There are various apps that allow you to accurately see what apps are using battery (in addition to the Usage in Settings). Lots of folks here seem to like Watchdog Task Manager.

Right I understand that, but what I'm really asking are those who updated to 1.58.502.1 from the older build, did you notice a decrease in battery life... Not trying to compare my battery life to someone elses, I get how that is an impossible answer.

How is asking if anyone is noticing decreased battery life after 1.58 any different from comparing battery life? Its the same thing.
I can guarantee that there are some people that have experienced worse battery life; and some have seen the same or better battery after 1.58 (as this has and will occur for any new OTA/RUU).
Not trying to be argumentative, but my point is whether folks have seen decreased battery life or not is somewhat irrelevant, and isn't going to solve your problem. Better to look into what processes are actually causing the drain, and go from there.
try booting into stock recovery and wiping cache partition...has helped some folks in past
I actually did what dudeluv said and am using ART now. Waaaaay better battery life, actually better than it was previously. Havnt ran into any bugs in it yet either. But we will see as time goes on.

Interesting, I would not have thought switching to ART would make such a huge difference. Thanks for posting an update.

Oh yeah, full charge yesterday, using it just as much as I normally would and when I plugged it before I went to be still had 86% battery life. Compared to being on 15% by 4 in the afternoon.
