Custom ROM with the best battery life :)

Hey guys,
I have played around with a few different roms for my SGS2 and was wondering which one has the best battery life in your experience?
Cheers

I honestly think stock ke7.

That's an almost impossible question to answer as there are so many different factors involved which can affect battery life both on a custom rom and a stock one for example.
signal strength
push
gaming
screen brightness
Everyone will have a different experience and your best bet is to try different rom's and choose the one which suits you as a rom which is great for them may not be great for you.

If some rom creator would make make a black-red theme for his mod it would be probatly the best mod... Of course with all other goodies and tweaks.
Black-red theme because it would drain the lowest energy from the battary in the standart screen mode, but since we all use mostly different apps with different colors it will vary anyway.

To be fair, although it is purely anecdotal, people who have tried different ROMS while going through the sameness of their daily lives should be able to make a relatively valid comparison of battery life.

All the custom ROMs out at the moment are extremely close to stock, so I doubt there's much difference.

2 days?? I'm gald to reach one day.. I just flashed lite'ning V 1.3. Hope to reach one day without any problems..
have a nice day

It appears the battery indicator is often way off. I let mine drain as much as it could til it would not boot at all, then charge it for 6 hours. Now it seems to last twice as long on stock (2 days with a lot of use)

I'm going to try this right now. I'll just let it stream some music over wifi at a high bitrate to drain it quickly. And using GPS, Blue-tooth. Playing music through PowerAmp at the same time.

i have a great battery life with KE8 guys... pls try it & then comment...
its too good...i recommend litepro 1.3 for every SGS2... its the best i have ever had so far....

Same here

That would be funny if a lot of the battery problems are actually because we keep thinking it is flat when it isn't - it is just being mis-reported. Kind of iphone batterygate in reverse.
I had a lock up on my device the other night but didn't realise until the following morning when I found the device unresponsive and stuck on my last screen. Although I had to pull the battery to regain control, the screen had stayed on all night because of the freeze and the battery meter graph was red for about 7 hours. The screen was still on and bright before I pulled the battery though.
Think I will also try ignoring the meter today.

stock KE2 and stock KE8 is best
ke7 is a nightmare

Using stock ke8 got about 30 hours with juice defender, constant wifi usage and app store and constant browser usage

Best rom for battery life?

Does anyone know the best fully functioning rom with the best battery life?
(Sense or AOSP)
Thanks in advance!

CyanogenMod 7 with tiamat kernel gets pretty good battery life. The kernels tend to have mor eaffect on battery life then the roms themselves.

Thanks!
And for some reason my gf's EVO is dying really fast. I mean it drains 1% every 5 mins.
I replaced the battery and still the same thing. It's running CM7.

Try MIUI with Tiamat 3.3.7 SBC

Sounds like she might have 4g running all the time. Or maybe she might be updating/refreshing her background data to often. Only use 4g to down load big files or steaming vedio. Check her 4g connection and turn off or her sync rate set it to every 3 hours or more. If one or both are the culprit then she'll see a big improvement.
I run EVO Deck rom with cyanogenmod love it. And every thing works.
Hope this helps

I figured I'd chime in because you said you wanted a fully functioning ROM. CM7 and Deck had always yielded the best battery life for me with the last rev of the Savage Zen Kernel, but if you're like me and are very anal about the phrase "fully functioning" then it should be noted that the AOSP ROMs don't have 720p video recording. If that doesn't bother you than CM7 or Deck all the way.
That said i'm running TommyTomato's Classic ROM with the Freedom Agressive kernel and I'm getting 25+ hours on a charge which puts it on par with any AOSP ROM/kernel combo I've run. Might be able to get a little better on AOSP, but I'd say that's pretty damn good and it's fully functioning as in EVERYTHING works 100%.

4G is never on, Background data is unchecked, Email is set to manual sync, brightness is dimmed, no wifi. I feel as if I've done every battery saving trick in the book.
But I realized yesterday that I had SetCPU at 700mhz to save battery. I uninstalled it and the battery life wasn't dropping so rapidly. I can't say that was the issue. I'll have to run a few more test.

I will definitely try that combo and see what happens. I always flash roms but never kernels, to scared haha.

I get better battery on drews ICS ROM Than any from I've run in a year. I use it as a daily, it isn't completely fully functioning though, as 4g doesn't work and video is iffy.
That said, after I updated to latest radio, my battery is dying much faster........did you do the radio update ?

If you're flashing ROMs, you're already flashing kernels. Don't fear the kernel flash. Tiamat Lee on CM7 or Deck's is where it's at.

I meant interchanging kernels with custom roms.
A lot of people are saying the same thing so I guess I'll try those recommendations.

I'm on Tommys Classic Supermagic,running the Hard to kill battery calibration script from Zepplins thread and i'm getting the best battery life i've had on any other rom and i've used this script with about 10 different roms,from AOSP to Sense 3.0,wont run 3.5 because of bugs and no 4G,after a full charge with alot of phone calls,texts and surfing,i held a charge for 4 days,it was 67% on the second day and actually died on the forth AM.

I'd definitely do a comparison between screen-on and awake time.
If you don't know this, you can access it through Settings > About Phone > Battery Use/History/Etc. See if the bar graphs of screen-on match awake. If you see a long bar under awake, but not a matching one under screen-on, you probably have a process or app that is stuck and needs to be removed/re-installed or have it's data cleared.
Note: it's normal to have some awake time that doesn't match screen on as apps/processes still have to perform there activities even with the screen-off, however, it shouldn't be a ton.
The best app out there to study this IMO is betterbatterstats. Hope this helps! Cheers!

Battery drain fixed on my Vibrant!!!

After flashing numerous ICS ROMS lately, I always seemed to have one major complaint. No matter which on I tried my Battery wouldnt seem to last more than 8 hours or so. Well, so far it's gone down only 6% in the last 6 hours with moderate use. here's what I've done (on Doc's Master ICS v5 Final, icyGlitch v14 b5).
***if anyone already has this listed somewhere, I apologize. I tried to find a post telling what to change and i couldnt so this is what i came up with***
1. set min/max cpu to 400/1000
2. use glichassV2 scaling gov
3. ns tools: active scheduler set to fiops
And I must say, Doc's Master V5 has easily got to be the BEST all-round ROM I've tried BY FAR!!! Vibranturk has damn near perfected this stuff.

Don't know if this is going to help, but appreciate you posting it. I have decent life on AOKP Build 26 with icy Glitch v14b5 with CPU set to 100/1300, Glitchassv2, default scheduler, and the 1800mAh battery. But if this helps squeeze a little more out, then all the better. Right now I get about 12 hours with moderate usage.
Sent from my rough sketch of a Vibrant on a brick.

I'm running TeamHacksung's build 16 and the main thing I've done for battery life is to customize the screen brightness levels. I had battery drain issues on it the first time I flashed, but I think it was because something I had done. I odin'd back to stock and reflashed CM7 then the TH 16, everything has been really smooth. I'll have to try out the changes you mention here to see how it goes... I'd love to be able to get the same or better battery life and more performance.

well, i made it to 12 hours. but about a solid hour and a half of that was playing Need for Speed Hot Pursuit so i imagine w/o that i couldve got quite a bit more life out the charge.
I had to turn the deep idle off when it came time to charge or it wouldnt charge correctly. and, for some reason it keeps saying that its 100% charged after just a short time. after a reboot the real percentage shows up.

You guys are on GLITCH kernel im guessing to get Glitchass v2 governor?
I shall try this for Euphoria today.

Can't believe i'm saying this but it truly does work. Usually after school my battery would go to a crawl to about 20% today it stayed up about 50% REALLY fantastic standby life.
Thanks OP

x66, if you want to get even better battery life, go into the display settings, in the Backlight settings, and you should be able to edit the 'Other Levels'... Bring those down a bit if you haven't already and you'll get even better battery life as you won't be using as much juice on your screen. Has worked out really well for me.

I am on AOKP M4 and I cannot find that setting... but its cool i'm getting amazing standby life.

Ok, so i tried the op's settings, and i unplugged 3 hours ago, and I'm still at 100%.... I dunno if it's a battery reading bug, but if it's not...wow!
Also, since doing this tweak, i got an upload speed boost....i dunno if it's related..

Edit...it was a reading bug....it was a battery reading bug...i was actually down to 50....but the speed tests....still dunno how i got such high upload speeds.

Samsung Galaxy S3 *AWESOME STOCK BATTERY LIFE*

THIS THREAD WAS INSPIRED BY MOST OFF YOU WHO ARE TRYING TO GET MAXIMUM BATTERY LIFE WITH SOME CUSTOM ROMS.
Before Galaxy S3, I had Galaxy S2 which battery wasn't soo good. I was always searching for battery friendly roms and I was flashing one or two roms every day.After every custom rom I was thought like that: Why I done that, when every stock firmware gives better result(battery life and performance) then any custom rom. I know that there are some excellent custom roms, for me ,these are STOCK LOOK roms with bloatware deleted and some unused apps. But, we don't need to flash them when we can do that alone.
NOW,I HAVE GALAXY S3 :
Let's see my result on stock battery,stock rom (4.1.2 , DDELK1,XXELLC), and with some apps turned off in application manager,battery saving is turned on just for color of backoground,nothing else.That was heavy usage,I installed that firmware updated, all appps that I am using , and charged it. Viber,WhatsApp,Instagram,Sync,Wifi,3G,Facebook,Gmail, are always ON.
Results:
4h of screen on,phone was used(wasn't just screen on) , 52% battery left. I lose about 3-4% maximum during the night ( 7-8 hours) with wifi on.
See this on attachments.
Mostly ,my battery lasts for 2 days, I achieve min. 5,5 hours screen on in every charge with hd gaming,facebook,gmail,whatsapp,viber, about 40min-1h talk in 3g every day.
My tips for battery life improvement are:
-Turn the Energy saving(I turned it on just for background color i vibration,if you turn on full battery saving you will get much better result, but it seems to slow and laggy)
-Turn off apps that you aren't using in app manager( Settings,Application Manager,All > than find apps which are unusal for you. I turned off : All yahoo apps,samsung suggest,google +,flipboard,dual clock,chat on ,all samsung hubs because they doesnt work in my country, google maps(I use google earth).)
That's all. Enjoy that battery,that performance and that beauty of stock rom

I can get 7.5 hrs screen on over 3 days battery was better on ics but still pretty darn good

Odp: Samsung Galaxy S3 *AWESOME STOCK BATTERY LIFE*
Hi Guys,
This is actually my 1st post, but I was looking around xda for couple of months now.
I am using stock rooted XXELLA with Siyah kernel. I can make my phone last easily for 2 days, with 2g mostly on, disabled lots of unused apps, lowest brightness, sync off, etc. and UC to 1200 mhz. I'm using pegasusq gov and noop scheduler.
But I can't imagine 4 hours screen on and get 52% battery left, or get 7,5 hrs totally. I always monitor the usage with BetterBatteryStats and when the screen is off I can even get about 4-6 hrs / 1%. But I can't reach >5,5-6 hrs screen on. Any suggestions? Do you think I can lower the min. brightness in build.prop?
Btw, I think if you share your battery stats, it would be nice if you also share your governor/scheduler and OC/UV values.

i do exactly the same thing like you did. I am searching for custom roms giving the best battery life with good performance. But it seems like i cant get over 4 hours screen on time (especially with data turned on).
I dont know how you got that kind of amazing result... 4h screen on time with 52% battery left. wow...
I never turned on power saving mode cause i just dont like the laggy system performance. do u have any advice what to do to achieve the same battery life without having a laggy slow phone?

I don't think it would make any difference, since I have only few apps, I don't like putting garbage to my phone Could you maybe share kernel and partial wakelocks from BBS, maybe cpu states too?
And again about the 4h screen / 52% left - how did you use the phone? I can see no games, so only web surf etc?
Sent from my GT-I9300 using xda app-developers app

Everyone uses their phone differently so comparing battery life is not possible, someone who demands smooth scrolling and instant response is not going to get 2 days use or more than 4hr screen on time.
Personally I'm not worried by stutters or lag, I'd rather get 9hr screen on time over 48hr up time - this is with a super lite ROM, I have all the bell and whistles turned off and all power saving options on, as close to AOSP as a stock based ROM can get.
I'm very happy with this phone, compared to my old htc sensation I no longer worry about battery life, I have two batteries which get swapped over between phone and desk charger every two days, unless playing games when I only get 1 day life.

I don't think this is all that spectacular to be completely honest. 4hours screen on time with 5hour since unplugged - pretty much nonstop use. Just my opinion though.

Hey op, sorry to say this but you might be wrong. For battery life it depends on kernels and tweaks rather than on roms. Roms are actually just themed/stock themed firmwares with additional apps/removed apps and pre-installed tweaks and kernels. Most roms use v6 supercharger tweak. For me I use phenomenal kernel which has undervolted and underclocked gpu and cpu. But if you want more options with oc/uv try boeffla kernel where there"s an app included that allows you to over/underclock you gpu and cpu. By underclocking, it will save more battery. My ohone lasted about 12+ hours of continuous use of my phone (gaming, watching videos) with the kernels I use

I have had over 8 hours of screen time, but that was literally not using phone just leaving screen on with videos playing for a lot of the time, but everyday usage using the Xperia Rom I get about 5 hours. I charge every night so don't need 2 day 3 day usage etc, unless my plane crashes onto a deserted island where I have to survive with no form of electricity anywhere.

Agree, the op's a total noob. Turning on power saving mode and closing apps is what an average user with common sense would do. What's so awesome and special about that. This thread is rubbish for advanced users but somewhat useful for a no brainer

s2 in jb 4.1.2 battery life

hi. I am o supernexus build 5 wth siyah kernel. I got round 7 hiurs if heavy usage on gs2. I've done facebook, viber, internet using stock browser and downloading around 200mb zip file. what can you say about this battery life. its my first time to use gs2 and I am using 2000mah. the battery life seems pretty bad in my opinion. I will attach screenshot of my hardware info, battery use and screen time. hoping for any opinions out there

I think is good , for me with stock battery (1650mah) i get 3 hours and 30-40 minutes (screen on time), wifi on , screen brightness auto
Send from my SGS2 I9100 with HassanROM and latest DorimanX 8.xx kernel

I think the battery life should be better with a 2000mah battery..
Is the battery properly callibrated??

oh really that means I should be getting better because I am on 2000mah but it seems not. Im not sure what's the problem if its the battery or the kernel. I also used an ICS firmware from Samsung I9100TDULP4. I don't know if that affects the battery life

Well I dont know if it is properly calibrated. By the way I got this unit from my uncle so I am not really sure if the battery is still good. How do we know if its still good. I dont know how old is this battery. How do we calibrate the battery and does the room affect this battery life?

I have suggestion for you , go to miuiandroid.com and download the latest build , install Siyah Kernel v6.0b5 with that and you will love the battery timing on that (Trust me, i am using it right now)

you mean downloading the miui rom? yeah definitely I'll give it a try after slimbean which I will try if I see no improvement on the bAttery. Has anyone had 2000mah and siyah kernel with supernexus rom build 5? What are your timings?

right now I am using the original 1650 mah stock battery of s2. I've been doing a lot of file transfers as of this moment via e.s. file explorer and currently I am transferring almost 13gb of data via wifi from my laptop. its been awake for 4 hours now with screen time of 1 hour and 30min. e.s. file explorer is keeping the system awake for 3 hours. I did some facebook and viber chats. screen at 35% brightness.. do you think this is the expected life of the stock battery? I am fairly new to samsung and I found the battery life to be disappointing even with the stock jelly bean rom from samsung. I will post some pics of the battery stats and cpu stats from cpu spy. another thing though. is there a good app from the market where I can test my two batteries and compare them? thank you

To callibrate battery..first completely drain the battery to about 5%, then charge the phone non stop without disturbing it till 100% and immediately remove the charger..again fully drain the battery and follow the above steps and u will get better battery life after a few cycles!
About roms..battery life does differ from rom to rom...i suggest u could check the custom kernels packed with zzmoove governor, ithat particular governor definitely improves the battery backup!
And in the above post es file explorer is eating ur battery..for that u should download greenify and hibernate apps continuously running in background!

great. I will follow your steps. one more thing. how can I know if the battery is still good or if its still holding the proper charge its suppose to have? thanks

best I can get is about 3 days standby in jb stock.

I use the 2000mAh battery is primary battery.. no big surprise to expect here, capacity is just 21% more by construction...
With wifi on, JB burns in my case about 3% in IDLE.. stock kernel.. and about 5% in 3G mode, IDLE.. then battery drains more or less fast depending on screen on, phone calls etc. I use the phone extensively for work (email sync & replies, phone calls, sms and voip) and i have to topup the battery twice or trice a day!
Have tried various custom kernels with all sort of magic to reduce battery drain.. more or less effectively.. sometimes with less stability.
Right now trying out latest dorimanx 8.27.. seems thatn IDLE with WIFI on drains around 2% per hour.. better than stock.. still not quite awesome
I miss the GB battery life.. but JB is so beautiful in comparison, I cannot go back!

Does Jb stock for you has better life or does custom rom have more? I really like the custom roms but as per observation stock rom offers more battery time. Right now I just reverted to stock rom i9100xwlss. Touchwiz really sucks. Supernexus is really beautiful but offers less battery (but I will have to try yet their latest build). Also one of the reasons for going back to stock is the camera shot quality. Custom roms really have poor camera quality. I guess when it comes to lowlight shots the stock roms are best. So much for that. Does stock rom offer more battry for you or custom rom does?

Below is a reply in some other forum by Samsung offcials regarding a specific method to Hard-Reboot your phone after a Firmware update: This method particularly helped me improve the battery life on SGS2 after 4.1.2 update.
"1. I’m sorry you are having issues with your device after upgrading the firmware. I can understand your frustration about this.
Old systems settings can be left on the phone after an update occurs, which is why we usually recommend a full factory reset after updating. If this isn’t done your device may begin to give false readings from system resources, or experience technical problems, which may explain the issue you are having.
We would advise on doing the following, which is designed to reset the settings on your device. Please back up your device using Samsung KIES before you do this.
1) Remove the battery for at least 40 minutes, put the battery back in and allow it to fully discharge. Afterwards, perform a full battery charge with the device turned off. Do not interrupt the charging process.
2) After the battery is fully charged, we would like you to perform a full factory reset, which can be done via Settings > Backup > Reset.
This process will reset your device, remove old system files that are no longer needed and enable your device to operate normally again.
Please let us know if your device continues to experience problems after the reset so we can investigate further.
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards,
Stewart

Actually I only use stock JB.. and trying to get it last longer with some custom kernels.. recently trying snapdragon rom, which is stock JB as well but with some S4 apk made compatible with S2... tried some time back omega, vanila rootbox and some other android builds for s2.. but was facing few stability issues / bugs and also missed some features that i was getting from stock rom.. so i gave up with these... now just aiming at stability and if possible battery endurance.. but not at the cost of stability.
