Hi
I'm new on this forum, have been lurking around before, but i digress.
I just got my SGII 2 days ago, and i'm in love with it (not literally, lol).
So, i already rooted it and today i backed up all my apps with Titanium Backup, and made a ROM backup with CWM.
Now, i find like many other users, that the battery life of JB is very poor on stock 4.2.1.
With WiFi on, and brightness settings on Auto, i lose about 2% in maybe 10-20 minutes.
When i game very shorty for only 5-6 mins i drop from 100% to 96 or 97% (don't know if this is normal or not with Minecraft and Asphalt 8, sometimes GTA 3 and Age of Zombies).
Now, with battery saving on, and brightness on the lowest settings (not auto), the battery life is alot better ofcourse, but still the battery drains pretty quickly when i'm playing a game (losing 3% maybe every 8 mins?).
Is this normal with JB or is there something wrong with my battery?
Also, if it's just the ROM, can you advice me a ROM with good battery life, preferably android 4.4?
Also, i read about Cyanogenmod 11, how is the battery on that ROM?
Thank's in advance!
Sorry if there'are any spelling errors, i'm Dutch
EDIT: sorry, my post was a bit incomplete
Battery resource usages.
Screen: 51%
Android-system 16%
Mobile standby 5%
Media server 3%
Those are some of the apps that eat up battery
3% in 30 to 40 minutes with Wi-Fi on?
I'd recommend you don't change a thing. Consider yourself fortunate because those are good numbers.
Unfortunately, Camera has stopped.

Sorry, corrected the post, 30-40 mins was incorrect
Also, another question, when installing a custom ROM, does it matter if it's a T-Mobile version or Vodafone?
Or doesn't that matter as long as its for the i9100?
Carrier specific custom roms ?? Not sure what you mean by that; there's no such thing.
If you mean 'Can I flash a stock rom for a different country or carrier ?', the answer is yes.
I strongly recommend you read the guides/tutorials stickied near the top of General section. This will give you a good grounding in 'the basics'. If you're going to be modding your phone at all, you'd much rather read & learn, rather than learn the hard way & end up with a busted phone.

Hi guys sorry for this thread new here so please go easy on me. Had a galaxy s2 for a few weeks now and i have to say best phone ever. Did the normal rooting and flashing roms and i have noticed recently that my battery has been going down quite a lot after a few hours. I tried roms like Villainrom, Cognition, Batista and etc which i find them very good but on my battery stats it says that i have high display usage and the percentage is like 56 - 85 and sometimes goes and stays to 91. i have since then when back to 2.3.3 stock firmware rooted it as well and i only have display percentage of only 25% which i think is normal and my battery lasts longer. I have spoken to Samsung regarding this situation and they are sending me a new battery but im just wondering why i cant flash a custom rom without having to worry about the high display % and what can i do to fix it? do i have to give it a few days for the battery to settle on the rom or shall i just stay with the stock rom for now till i get my new battery and then try to flash? sorry for the long essay i just need to find out if any one else had the same problem as i really like to use a custom rom that my normal one.
THanks
I too find it very hard on the battery with all the custom roms that I have tried out. I tried, Villain, Cogniton, LeoMar, Batista, etc..etc..etc. I have in fact tried out all the ROMs out here. Tried even different combinations of Kernel, but all only lead to the frustration when it comes to battery life. I finally tried MIUI ROM and I can say that it is giving me very good battery life compared to other ROMs.
It is interesting to note from you that the STOCK ROM has given you better battery life. Could you please tell me how long did your battery last in Stock ROM and what are the Apps that were running in it?
Install Better Battery Stats, I don't think anything wrong with the battery.
See under Wakelocks what apps/processes are going in background and causing the drain. Then take necessary steps with TB Pro.

to xdadeveloporian: thanks for your reply bk and sorry to hear that you had the same issues. like i said above i am very new to all this so apologies if i am replying with noobish comments. with wifi on and the normal widgets i had a battery life over a day. only charged it once and it still going. is that rom that you using now good?
and to ithappy sorry what do you mean by your reply i do not understand sorry. and do you guys think with a new battery it will fix my problems and i will be able to flash roms or do i have a faulty phone?
% is not important, what really matters is total time on for the display. Are you sure it isn't that the stock ROM burns more power in other areas, so the display is less? Or maybe the brightness is different? I'm not even sure how the display proportion of battery drain is apportioned - is there really a current sense integrator?
now that i have the stock rom with firmware 2.3.3 display is 30% followed by android os 15 - 19% which i think is normal into regards were i was on customs roms and the os was 15% and display 50% and over. brightness is basically at the lowest i can put it i am using touchwiz launcher and i only have two pages with widgets and nothing else. just a bit confusing thats all. i mean with custom roms the battery should be alot better not the other way round if you get me.
apologies if im not making any sense here. thanks again for all your replies it does help

I don't believe that stuff, why battery life would be better in a Custom ROM, because they added/modified some stuffs, nah. You can make a Stock ROM custom with some little modifications if you are rooted and have great apps like Root Explorer, Titanium Backup etc. I, for me, will never ever use a Custom ROM. But that's just me, don't take it any personally.
And about battery, don't see that how long are you getting with it, like- 1 day, 2 days, they don't make any sense, just keep an eye on the 'Screen On' time, if that is around or above 5 hours then you are very fine. And also keep checking that your Awake and Screen On bar is synchronized or not, if it is not then you must have something going on background, like- Latitude, Email exchange etc. which you can see under Better Battery Stats. And also, when not needed turn off, 3G, Packet Data, WiFi, Auto Sync, Background Sync and check how many apps are on Auto Sync, if not needed then modify it to Manual Sync.
Regards.

Maybe they fixed some bugs - specifically a custom kernel might have improvements or bug fixes (since there is lots of work going on here from many companies making contributions). This takes time to filter through to the official ROMs.
Maybe they removed some of the stock apps which contribute (maybe only slightly) to power drain.
Maybe the small differences in the ROM mean that existing bugs are less likely to have an impact, so even not fixing the bug it seems to have gone away.
Custom ROMs are as likely to make things worse - but if many people are affected then it is likely that someone will track down the reason.
Look all i know is that as soon as i started flashing custom roms on my phone my battery life has been going down like hell. Checking battery stats the most thing that is taking up battery life is the display being as high as 80 even 90 percent. I am not a expert on android having had an iphone all my life so when people say underclocking and other stuff its like new things to me so i do apologise for being such a noob. i do love my galaxy and i think its the best phone out there at the moment. all i need to know is if there is something that i can do to bring the display down and not to have it drain so much out of the battery..
Thanks again for everyone for replying
very niceeeeeeeeeeeeeeeeee
huh? has anyone else experience high display usage on their phones when checking battery stats?
is that from the android market i can get that app?

Hi there,
probably that request would make more sense in the developer forum but i didnt post enough yet
Actually i get insane battery batterylife with the bali 1.8.8 UV version, therefore i tried the non UV version with even more lowerd voltages via set cpu. it was stable but drained a lot faster. don´t know why.
so my request would be "pre-undervolted" bali kernels that might have even longer batteryliftime. Any hints on that? Someone who is able to compile something like this?
Best regards,
vibrantoparanto (from germany)
Hint' Bali X+Voltage control app= win !!!
Sent from my SGH-T959 using xda premium
^^ that is your answer....currently what im using
bali-x is what i used before - i lowered the voltages up to -150mv with some frequencies but it still gave me only about half the battery lifetime (less than 24 hours with moderate use) then i get with bali uv. What did you use to manually undervolt and how is your battery lifetime?

i hate to burst your bubble, but youre chasing a ghost. uv'ing will not produce very noticeable changes to your battery life, especially if were are talking baout different versions of the same kernel.
take a look at this: http://forum.xda-developers.com/showpost.php?p=21024393&postcount=8
Cannot agree with that. I tried *a lot* and flashed different roms and kernels for years now. With stock kernels i get up to two days standby with low/moderate use, with bali UV i get almost three days. I have no idead why, but at least the standby time differs dramatically between kernels. At least thats for sure - under load that might be another thing. But probably you´re right and its just a "good standby behaviour" which would hardly benefit from lowered voltages. Would be still interesting to try a hardcore UV kernel
TopShelf, it is funny that you posted that note/post b/c I was just getting ready to PM you that I put part of it in my guide like I mentioned a week or so ago and the apps too.
Take a look at the Guide and maybe you will find some answers to your questions.
If you want to UV to the max, then you will have to test that yourself b/c every Vibrant reacts differently to OC/UV. Step it down -25v each day (don't set on boot until you know they work) and see where it freezes. There are OC/UV examples in the guide but beware, they are both for MIUI kernels.
Is there probably any admin out there who understands what i talk about and can move that thread to the developer forum?
this thread belongs here, you posted in the right section. posting in development will not get you answers from developers, it will only get you yelled at by hall monitors.
it is a common misconception that "developers" ONLY visit the "development" section. this is far from the truth.
sorry to say, the reason you have not gotten answers isnt because you posted in the wrong section, but because requests like these are pretty much never honored. the reason is because if a developer decides to make a slight alteration to a ROM/kernel for a member, he will then get BOMBARDED by dozens of other members who have tiny little tweaks that they would like in their ROM/kernel
Still trying to bring back some life to my request with this argument: I just checked my girlfriends device (using zendroid 2.1.2 with bali 1.8.8uv) and couldnt believe it: 3 days and 14 hours since unplugged with 8% left. The battery is a stock 1500mHa. And as its my girlfriends phone its definity not "overtweaked and calibrated". Personally i care much more about standby time than super heavy usage (guess that should be fine then too).

Since you didn't like the answer you got, for clarification purposes you are basically asking for a dev to use their time for FREE an modified/debug/test a kernel with your requirements just for your own sake ?
i wanted to point out that this is a very interesting kernel with great battery lifetime. if you have a look at all the other threads of people desperatly trying to get 24h of battery then you probably wouldnt consider this request as "wasting free time of others for my own sake".

i can prove to you that UVing does not make that much of a difference. if youre willing to learn, try this little experiment:
-UV your phone using your current settings
-put your phone in airplane mode
-turn it off
-charge it to 100% while its off
-after it boots up, leave it in airplane mode and immediately lock the screen
-let your phone sit idle in airplane mode from full charge to death (record the time)
--------------
Once youve done this, repeat all of the above steps but with STOCK VOLTAGE. record the time.
now compare the two times. i would be willing to bet a large sum of money that it is not a notable difference, if any.
my point is instead of trying to convince yourself that your theory of UVing is correct, why not do a TRUE battery life test, and simply find out for yourself. you cannot run true battery tests while you are actually using your phone becuase phone usage is massively different on a day to day basis, even if you dont think it is, it is. there is background data, text messages/calls, notifications, etc. (which is why i said to put it in airplane mode, that way its just sitting there, with little to no variables)
i guarantee you that you are putting way too much thought into voltage settings. they do not help as much as people want them to. dont say im wrong until you actually try what i said above. although youre probably nto going to.

sorry, but this does not prove anything. what are you comparing it to? your phone? you cant compare her battery life to your own unless you guys have the same exact setup, same exact apps, and same exact usage habits, etc.
you are not going about this battery things the right way. you NEED to be willing to learn more instead of trying to come up with your own reasons in your own head as to why your battery gets a specific lifespan. If getting THAT MUCH more battery life was as easy as UVing your phone, dont you think the manufacturers would incorporate that and use that as a marketing strategy?? "New from Samsung, the Galaxy S III!!! This will revolutionize the mobile industry, curing the battery woes across that smartphone world...now with lower voltage for drastically improved battery life!! Pick yours up today!!"
It's not that easy, you need to read up on what affects battery life.
thank you for your thoughts topshelf, but as i posted earlier i am on that topic for years now and i really tested a lot. not as scientific as running phone on idle with different frequenzies but trust me: I know a whole lot about this topic. Also i share your thought that the voltage is not that important in the end. On the other hand i have to say you guys are quite ignorant about my observations i did earlier:
1. The bali-x kernel with manual undervolting provides (provable) worse battery lifetime than
2. the 1.8.8uv kernel.
Conclusion: As you say it is not that much about the voltage but about the way the kernels work as a whole. On the other hand it would be *very* interesting if the insane battery lifetime of bali uv could be even further improved. And no i wont put my phone to sleep for days in order to do scientific test (whoever is willing to i will donate - battery lifetime almost like astrology)
Last but not least: It is true that different roms provide significantly different battery lifetimes - for whatever reason. Some roms turn your phone into a handwarmer, others give you almost the standby times you were used from the non-smarthpones. And i think even the big companies have a hard time to write device specific code that is highly optimized - i mean you still get new devices with gingerbread instead of ics and so on. conclusion: on the software side *is* much room for improvement if it comes to battery lifetime on most devices.
just my 2 cents

Look at your post, you and "others" are asking for some one to do research and development on their free time and for free ? little selfish on you.
Look at all the kernels thread in the development section and read thru all the comments, I bet there is far more people whining and complaining about this and that, than providing actually constructive and monetary feedback to the developers.
Its not as easy as it seams, ecotox already tried this before with his ultra low power kernels and some reported great succes while others couldnt even boot, it goes down to the quality of the silicon on each particular phone. no dev has the time/money to develop such request considering all the different variables involved.
lastly if you are so fond on this idea, why dont you take the initiative and learn to compile and patch and make your own kernel ?

im not trying to pick on you, but this sarcastic response shows your overall attitude that jrafael is trying to make you realize. you want somebody to take time out of their day/night to do something for you...yet you arent even willing to let for phone sit for a day in order to learn a thing or two...letting your phone sit doesnt even take any effort, compiling a kernel takes a lot more effort than that
i hate to say it, but why should someone help you, if you dont want to help yourself.
thank you jrafael for the links - thats a great read.
@topshelf: still think you overreact here. For one who has developed it and has the workflow it is a matter of a few minutes - and no one is forced to do anything unless he thinks its might be worth it - maybe its inspiring? i am just asking. not everything idea must be done by the one who thinks about it. and the quote about battery life is true i would say - we are really lacking valueable info on battery drain with different setups.
Anyones gs2 seem to drain battery quite quick? Ive had a few android phones and the gs2 battery seems to fly down.. Im a heavy user most days like get up in morning facebook and apps all day long.. Strange thing is though i get about 5 mins worth of usage before it drops the first line off the battery.. I get max of about 5 hours of heavy use before i need to recharge.. This normal for gs2?

I am using the stock ROM and not having any issues with the battery lasting less than a day. I had to make a few changes to the settings, but once tweaked I am really happy with it.
Normal for me... a day and a half of light to moderate use. Plenty of syncing every hour, lots of Wifi and GPS, never switch any radios off, lots of FM Radio, auto brightness.... blah blah.

You're phone is active most the time, rarely sleeps. If you compare with mine above, you notice that the activity is in short infrequent bursts. The screen being on takes a huge amount of power - it's a big screen. And OLED.
I would say considering the sheer amount of use you give it, it's doing rather well... NO comparable smartphone (except the Razr Maxx) will give you much different. It can't.
By the way. not sure why the battery falls off a cliff from around 30% in your pic - scary!
1st, the post was apparently originally posted in a different location, then got moved to the Q&A section by a moderator.
2nd, your screenshot has what looks like a LOT of screen on time. What are your display stats for screen on time? (hh:mm:ss) From my estimation just looking at the bar graph, it looks like you have over half, and nearly 2/3, if not 3/4 of your overall battery time with the screen on, and the phone being "awake". With your overall battery time being 7:16:39, from your screenshot, that's about 3.5 to 4 hours of screen on time? If you are constantly using the phone, or keeping the screen on, it logically follows that the battery will drain.
3rd, JJEgan's point was this: This entire forum is meant for developers. (the name of it is "XDA Developers", after all) Yes, there is a Q&A forum, but more and more, users who are not developers are posting all over the boards stuff like "why is my phone doing blah blah blah" on commonly answered questions, (which is a clear indication that they didn't look or search very hard for the answer, even if they say they did) or, even more offensive in my opinion, "upload XXXX file for me" without so much as a please.
Non-developers are welcome, obviously - heck, anyone can join. But more and more people completely disregard the forum rules, which are plainly posted for everyone to read at the very top of each forum section.
Ahh ok.. Sorry.
I joine the forum as i have a genuine interest in all things phones wise.. Wether that be cooking roms, mods tweaks etc etc.. I dont come on here on the sole basis of asking questions.. Every now and again somethings niggle me about my device so the best place for info surely is xda developers. Though i only use the app at the minuite to view posts i did'nt actually know where the search link was. Though now i do i will use it...
Anyways:
Yea i did notice that big drop on the end of the battery stats.. Thats happened a few times ive noticed.
Dont think ive seen anyone elses screenshots look like that.. Could it be a sign of a dying battery? Or just wrong stats.
Ive read that the battery stats clearing does nothing as the stats it shows is whats using the power n not actual battery level.
My phones only about 5 months old too so everything in it should be in as new condition.
Strange..

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
5) Read about jb settings/issues.
Sent from the little guy
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.

S2 battery life
jsiv said:
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.

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.

Do you calibrate battery after every ROM change?

Can you please point me in the "settings" direction? I think I'm doing all things right, going real low on app usage, sync-ing of apps, screen settings, etc.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

Cyanogenmod roms are very fast ROM they are good as hell
Ur problem is genuine go to the playstore and download battery calibration app and follow the instructions in the app charge or battery up to 100 % and caliberate the battery u should have made an nandroid backup before upgrading

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.

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

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.

As far as the battery issue is concerned,do a clean ROM install through Odin.

at first: this is not a "whats the best rom" thread.
i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.
1 each phone is different depending on what's installed and running.
2 read there threads or flash each ROM and find out that way. You forgot about aokp?

2. thx for informing abaout aokp!
1. im asking for someone who did a test with the same phone and all roms. i dont ask for different situations, i sked fpr idle time and features!
Probably there is somebody out there who testet it and can present his results

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

Thx for your long, interessting and helping text!
im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.
greetings

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..
Sent from my GT-I9300 using Tapatalk
Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work
