Hi there folks! So, the galaxy s2, it's an awesome phone, the best i ever had, probably as powerful as a decent netbook. almost impossible to make it lag, the screen is awesome etc... but there's a serious drawback, which is making me want to go back to the iphone4, the battery life. i know, there are bazillions of threads about it, but come on, all people reply to those threads are suggestions, almost placebo like. e.x. "use juice defender", "turn off wifi, gps..", come on, these are not solutions. even with minimal usage, i can barely get a day out of my samsung, with heavy usage, i have to charge it 3 times a day, and considering that it uses a stupid and extremely low current limiter through the chipset (around 500 mili amps?) it takes 3 hours to charge it. for comparison, i have a asus transformer with the keyboard dock, hell, this makes me even more sad with the galaxys, as the transformer, lasts a whole day (at least 14-15hrs) at 70% brightness while gaming.
so, what the problem samsung? I'm using Ninphetamine's kernel with lightening rom (all up to date), i tried other kernels, other roms, but all of them have this issue, even when everything was stock, a day of minimal usage. here are some screens, android os is consuming most of the battery, does the section "android os" also include the kernel battery consumption?
is there a extended version of the android built in battery usage, a more specific one?
Works fine for me. Get a grip and read around. Easily get 3 days with average use.

I hope you wipe battery in between your rom flashes...
I am Heavy user and it lasts me around 13-15 hours and am on stock not rooted.
Besides was curious How heavy you use it cause If you are like sitting whole day with it you are better off on the computer I guess

If you are using ninphetamine and an android 2.3.4 ROM and still having battery issues, it's your problem. You have an app installed that drains battery, this is not a suggestion, this is fact. Do a completely clean install of an original dev rom, remove google latitude if it's included (known to drain battery).
If you aren't making it through atleast a full day of heavy use with that setup, then it's a hardware problem and you should RMA it.

well no, i never wipe my battery, why would i ? battery drainage by android os seems to be consistent. well just in case its a magic trick, i'll try it now
The transformer is a tablet, of course it has space for a huge battery extended by another huge battery in the keyboard. Perhaps you have a faulty battery that's not keeping charge well because I get nearly a whole day on a single charge, med to heavy use. And juice defender is a legitimate program that actually works, its not a placebo. Get a grip and stop blaming legitimate programs, or else no one will take you seriously. Read around, try some different roms, but it might just be a bad battery, if you have warranty, get the battery replaced. It couldn't hurt to try.

Well threes your problem. Its not a magic trick, its fact. Do it every time you install a new rom Also, as I said before, it might be a hardware problem.
15 hours off charger, 53% battery left, 1 hr voice calls, 1 hr screen on. Not bad I'd say. I've maintained everything on except bluetooth. I have google talk, and trillian, whatsapp, facebook, tuenti, push email and a couple other things going on in the background like twitter and such, and I couldn't be happier. Well, if it could make me breakfast . I'd say you're doing something wrong. Stock, 2.3.3 not rooted. I'm just a normal geek joe!

So far I've used VillainROM with ninphetamine which gave great battery life, and MIUI with the kernel included which is also pretty good (not as good as villainrom with ninphetamine though). As daily ROM I use MIUI though since I love the interface and theming options.

I wouldn't suggest Cyanogen at this time, it works pretty well but it's not a stable or near final release. Also you can't use ninphetamine with Cyanogen without breaking things since ninphetamine was made for stock ROMs.
Battery wipe DOES help. I can say that with confidence cause I have seen the effect.

Like everyone said: Wipe Battery Stats, and/or switch to VillainRom. I dont think Lite'ning produces the best battery life in my experience. I couldnt stand the rom.
And one of the good things about Android phones is that you can buy an extended battery from ebay. They're quite affordable as well
I get crazy battery life on Litening rom. You need to do factory reset before or after installation.
Hello, i just bought an atrix on ebay with alien4 and was wondering if i should stay with this rom or not? I have no mod experience on this phone. I would like to get better battery life and get rid of blur if possible. It might just have a weak battery, but it goes down fast when im not even using it. I believe it is unlocked bootloader. I dont want to go crazy, just like a nice setup thats fast and good on battery life. Thanks!!
Try the current rom out for a while, and then give CM7 a shot...

There are a few different choices. Definitely get comfortable first with flashing ROMs. Use the guides here in the forum to teach yourself how to do it. After reading the guides, read them again. You do not want to end up bricking your phone.
A few I myself have tried are CM7, HomeBase and Aura. I use HomeBase as my daily driver. My battery life has been pretty good. I usually get around 36 hours with pretty heavy usage of streaming music and videos.

I would give HomeBase a spin, but just remember that the de-blurred Moto ROM's do have certain things missing just have to read about whats there and see if you can live without it. I personally use HomeBase 2 which is slightly de-blurred and it looks and feels like a vanilla ROM. Some blur is good. Definitely read through a few posts and guides in the Development section to get a handle of whats going on and then start trying things out. I don't know what recovery you have but I would suggest first going to this link and learn a little:

Then going to this link to get the latest recovery (it will save you some headaches):

As for the battery thing, try calibrating. If that doesn't work, it could need a battery with it being a used phone.
I tried Homebase and Aura a couple days ago, and I went back to Alien#4. Couldn't put my finger on why I didn't like them. But you should try all the ROMs you think you might like and see what works best for you.
I get really good battery with light-medium use, and my phone is very smooth. So if it helps, here's my setup:
Alien#4
Faux's OC Kernel 2.0 (to 1.3GHz)
Undervolted (75, 75, 75, 75, 100, 100, 100)
SetCPU "Screen Off" Profile to clock down to 456000Max
The biggest battery killer by far with that setup is the screen. There's a mod in the development forums that can lower the brightness much more than the stock minimum, but I haven't bothered with it. I only use my phone in quick bursts most of the time; check an email, send a text, etc. so it's not that big a problem for me. I can go couple days without needing a charge.

It all started back in May. I purchased my first "smart" phone, and caught a qbking77 video on how to root. Now I'm addicted to crack, and love our awesome devs. They have done so much for me, if they had car trouble, id be the first to lend my hand. On to my question now. I realize our hardware doesn't respond the same to various roms, but why is it, even after multiple epic 4g's, does MIUI always have the best battery life? I know its not fully complete, but it just rapes the competition. Any knowledge here?
Sent from my SPH-D700 using XDA App
probably because as you said, its not completely running everything the hardware can so it uses less battery
From my understanding though, mms and 4g still aren't working, which I never use anyway, and these are huge bettery drainers for a lot of ROMs, so what gives? 4g is sprints joke laughing down on us. MIUI is an asian based software right? Is it the 2.3.7 tweaks that make it better?

i guess each device is different. before i went to gb, i used to take my phone to the gym with me as for music. i usually streamed pandora, sirius, or googlemusic, sometimes listening from my phones hd. I would go to the gym about 1.5-2 hrs and leave with about using 25-35% of battery avg. With GB, i used about~20%... but this is only 2 days so far..
Well, I've been flashing and testing a hell of a lot of Rom and kernels lately, and the best battery life seems to be with SenseiSimple's SleeperROM. I use the latest version of earthbound [iap]'s Samurai kernel. That kernel allows for a hell of a lot of flexibility in terms of frequency and voltage, so you can fiddle around a bit to find a combo that works for you best. The SleeperROM already uses the Samurai kernel by default, but it is presently still compatible with the latest BETA version.

Hi all,
Just wondering if your all seeing reduced battery life with the ICS builds for the DesireZ?
I was using Miui (2.x) and now trying out Ice Cream JIBWich,and Im discovering the battery life is most certainly less. I've also tried CM9 Alpha and Andromedus r13, all roughly the same.
Battery Widget reports on average 40(ish)mA in sleep, I havent compared it to Miui but just wondering I've done something wrong here..
Install procedure this time was a factory wipe.
Comments?

I don't know if my battery life is worse on ICS than on CM or stock 2.3. Because I don't have any logs of battery life. Maybe I will do some tests in next week, just for curious.
So... I'm getting 30mA - 34mA drain on idle on Andromadus v13 with default kernel. It is lower than yours. I'm using latest radio now (.19).
After implementing new features and fixing bugs, there is a stage of development called optimization. That is when you will see all the battery life milked out of a rom.
And none of the ICS roms are even close to that stage, so battery will probably not be indicative of the final product.
I don't have any hard numbers, but based on my moderate usage, (8am to 11pm) I go from 100% to about 40%. Fairly good IMO when compared to sense roms (that i'm used to) but not as good when compared to AOSP GB or MIUI roms..
Hmm I found my battery doing suprisingly well compared to aosp gb, now that I'm using ics its lasting longer than ever.
It probably has to do with better app/process management.
That's my experience..

Well, this might sound strange to say but i'm actually getting the best battery life i've ever had out of ICS so far with Andromadus v13/Jibwich 1.3 on my phone. I seem to manage to get really long charges of at least 48 hours. Maybe i'm not using my phone as much as i was with GB? I'm not quite sure if that's the case or not, but i'm consistently getting longer lasting charges than ever before with GB.
Thing is though that ICS ROMs DO seem to drain the battery more while the phone is actively being used (in comparison to AOSP GB ROMs), this seems to be the case for me, as well as some other people that i've seen.
There were a few strange versions of Andromadus and Jibwich though which seemed to cause severe battery drain for me. Fortunately, that hasn't been the case with any of the latest versions.
All of that said, i still don't think anything compares to the battery life on G2 Slim (Gingerbread AOSP ROM), that ROM has ridiculously good battery life. With that one, i'd use my phone a fair bit (couple hours of tethering, gaming, lots of texting and calls) and it would still last for at least 44 hours or so.
In the end though, there are still some GB ROMs that have much worse battery life than ICS for me. For example, all CM7 variants that i've tried has always had this frustrating radio related battery drain, then some Sense ROMs seem to drain the battery a bit more than AOSP ROMs too. In response to the OP, i never really got amazing battery life with MIUI, so ICS has been a much better experience so far in that regard.
What i do know for sure though is that battery life with ICS is MUCH better than the stock gingerbread OTA update that our phones got.
thanks all,
I've done some checking and according to battery monitor, my JIBWIch rom seams to be fluctuating .. from 36mA to 97mA in standby which to be indicates something's running.. not sure what... Anyone recommend a decent process monitor, there's soo many of them

Agreed..
I'll see how it goes but I might have to go back to Miui (GB) as I use the phone for work..

Here was my (personal) record breaking charge on Andromadus v13 https://www.dropbox.com/gallery/12263406/1/screenies?h=c9ef42
You can see part of my configuration there (radio and CPU speeds).
On top of what's already there, i use supercharger RC6.9 with option 6 and nitro-lag-nullifier.
here are my usage patterns for good battery life:
-I generally stick to 2g networks as i don't do much web browsing while i'm out but when i do, i just switch to 3g.
-I also don't regularly use any task killers but if i detect any choppyness i kill app using Advanced Task Killer.
-I don't use auto-brightness and instead i just use the notification power widget.
-I do lots and lots of texting, some calls here and there, i often use wifi hotspot and i play 2d games a little bit at times, so i'm generally a light-moderate user.
-I also "debloat" as much as possible by getting rid of any system apps that i don't use.
On a random note, right now, i'm using Jibwich 1.3 and it is so great, battery life seems the same as andromadus v13 but this ROM is actually much more smooth and fluid on the home screen.
I hope this helps a bit, give me a thanks if you found this useful ;D
hey thanks for this, yeah very nice!
Just occured to me, im currently in Madrid (Roaming), and the phone's on 2g at the moment, I WONDER.. just wonder, if its constantly hunting for 3G signal.. now that would account for the random power demands...
Meanwhilst I found this app http://androidadvices.com/save-battery-android-phone-enabling-2g-network/
Apart from adding a 2g/3g toggle it also makes the phone go to 2g when sleeping.. I mean when its sleeping we dont need 3g access....
Anyone else tried it? or can recommend a different better/app?

Go to settings --> wireless and networks --> mobile networks
Now see if you have "use only 2g networks" checked. If you do, that'd be why you're always connecting to 2g networks.
As a battery saving tip, it's best to always check that option when you don't need mobile data (like when you're at home and wifi is available).
In addition to that, if that option is NOT checked, then your phone will connect to 3g networks where applicable, you have to check if your carrier actually uses 3g networks on your plan.
Also that app seems fine, but i wouldn't use the "use 2g when sleep" option because that could cause problems with reception between waking and sleeping because it'll be erratically switching between basebands all the time.

It looks to me that yes. Tried 3 ICS inluding JIBWich and CM9 based and battery life was reduced to me about 1/3 maybe 1/4. looks like that. Hope some improovment will come in near future.
I'm running Andromadus v13 and it seems to be only a bit worse than the latest CM7 nightly. However, this is only my subjective opinion, it could be that I'm using my phone more with ICS
I also have the .19 radio and the tweaks associated with v13.
Well from what i've seen, ICS has very steep and sudden drops in the battery stats graph when the phone is being used. This is in contrast to many gingberbread ROMs which just have a sloping negative curve on the battery stats graph. This seems to indicate that ICS uses more battery when the phone is being actively used.
I'll post pics after this current charge is over to show a comparison of ICS battery life with Andro v13 and GB battery with Virtuous G-lite 2.0.1.
I don't see any difference between GB and the ICS battery usage, maybe because i allways configure it from begining and don't restore apps via titanium backup or any other app...
Also battery needs to calibrate under new ROM and after few charges you will see it working little bit longer and longer...
ps. Do you have disabled Google Talk on ICS fresh install? He is always on after installing and eats a lot of battery.

I also configure all new rom's from begining and on Affinity 2 - my battery in averange usage die after ~16h but on ISC os about ~13h, I don't know why.
My battery after full charge get 4.212 V , tried clear battery stats bin no effect
My avg runtime on one charge on CM7 w/o oc, with ilwt or pershoot kernel is 60hours (yes! 3 "work days") or atleast 2 days with 50-70 min calls and 25-35 SMS
Turning data and/or wifi when needed makes phone battery least looooonger...
Now testing Andromadus Audacity b1, charged 7.5h ago (4207mV), i will post when empty (or near ~3600-3650)
Also remember that we don't have the proper kernel source for our phone. There are some tweaks that can't really be made yet, and probably a bunch of wasted cpu time where errors and stuff get worked through.
GB battery life was worse than Froyo at the same stage of development. It'll even out better when we have the official kernel source for the DHD, I think.
Sent from my HTC Desire Z using XDA
So most ICS based roms have roughly the same battery life?
I'm current on the audacity beta, getting about 20 hours with no charge with moderate use. Gingerbread i could go about a day and acouple more hours.
I'm a bit bitter that I can only use 3G or higher on Bell with my DZ...that means if I want better battery life I need to ditch mobile data altogether. Boo.

Better battery life
All,
I was just about to install "Elitemod", which claims to be tuned to bits wrt battery life, and I noticed AudicityBeta1 was released.. so i thought Id try it out.. and
And yes I think its much better!.. this morning I used it a bit, made a dozen phonecalls, sync'd email and for the first time the "voicecalls" are less than the screen.
(see attachment)
Im wondering if the recently released qualcomm drivers made a difference..
At this rate it will last ~40hrs... probably less but as long as it lasts the day Im happy
Anyone else want to confirm my findings?
Hey guys,
I think I read somewhere that threads like this are not really wanted here? So I'd like to clarify first, I'm looking for certain aspects and not for "the best" rom or whatever. If there's more than one which would meet my criteria, feel free to just name all without any opinion to it
There are just so many roms and kernels and I'm having trouble finding information what they can and cant do...Sometimes it's just a download link and thats it!
I will be travelling with my Nexus 10 and would like to use an internet dongle via USB OTG to access mobile internet in the various countries and I would like to use OTG for storage (usb sticks i guess).
Also it should be stable/fast and I would like to somehow prolong battery life (UC/UV? Dont know anything about that yet but I guess that would be how?), just in case I won't be near a power outlet for a couple of days.
I don't really care too much about design, so minimalistic is best!
Which kernels can I use? Does the rom even matter? are there certain roms that seem to work best with the kernel I would need?
Thanks for any help!! I will get the tablet the day after tomorrow so it'd be awesome to have some information so that I can root and start trying stuff out immediately=)
If you seek stability then go for CleanRom and aosp+ kernel. As for battery life there isn't anything magic out there, just turn the WiFi off when you can.
UV doesn't help, no matter what you will be told, it's just placebo.
I've used mrRobinsons AOKP PUB ROM + Ktmanta kernel for the last 2 months. Just took it on a long trip, used a 32gb USB OTG just fine. I watched several movies and had great battery life. Performance is awesome too.
No experience with an internet dongle, sorry. I just use the hotspot function from my phone.

It bothers me when someone says that such and such is the only stable combination, it obviously isnt or no one would ever run anything else. I have never had problems when I ran AOKP, or when I used to run CM10, or running on Rasbean which is based on AOSP. Each kernel can have certain releases that have issues, just as Craig's AOSP+ kernel could at some point, but not every release has always or will always be unstable. To my knowledge only Franco's R12 has issues right now and all other kernel releases are fine. Franco's R11 is perfectly fine too.
Also I can both mathematically prove undervolting can save battery and can show you plenty of people with actual experience on it saving battery. So you should really stop going around and spouting off "facts" which are completely untrue. But you are right about there being no magic stuff, it is all science.
I get wonderful battery life daily using KTManta and a tweak of the CPU/GPU. But then, my tweak stops doing so well if I use a CPU intensive app like FL Studio. I can go about 12 hours or more and still have 30-40% of battery left, with off-and-on usage all day including some gaming. Extended gaming (I'm talking Asphalt 7, Shadowgun, not Plague Inc) will murder that, but that's what I set up my CPU/GPU to offset.
Also completely stable with RootBox ROM (or CM10, or AOKP, etc) so long as I don't try "hotplugging"
