Hi Guys,
I am on the Three network in UK. I recently updated my to JB and immediately noticed that the battery performance has deteriorated. I used to get nearly two full days with a 2 - 2.5 hours of screen time, 1 hour talktime and 1 hour music and little maps with GPS. I can merely a day now with the same usage. I would like to mention that the standby time was brilliant on the last update I received on ICS. Is anyone facing the same issue. I am thinking of of doing a full factory reset. Not sure if that will solve the problem. The battery graph shows that something keeps the phone awake

I flashed the french version last night and I literally only got my S3 yesterday too and I can't really comment on the battery life compared to ICS but the battery life is way better than on my Xperia Play... Anyway I intend on trying out CM10 soon.
for me the other way around
ICS used to eat battery faster.
everything depende on how you setup and how you use your phone. it's not as simple as ICS > JB or JB > ICS
All the leaks I used, including the Polish Rom, had rubbish battery. H3G is working fine. Even better than ICS (or about the same).

Yep getting similar battery as that screen shot... Seems to be a lot of wake locks also I have realised even with data turned off it still drains battery as if it was on... On ics with data off I would lose like 2% over night bit with jb data off I lose 10±% battery easily over night... Hoping this is fixed soon... I though jb is suppose to be more efficient than ics?

I know how to disable Google Now, but how to disable S-Voice on a stock (unrooted) ROM other than simply "not using it"?
Like an earlier poster, I used to get huge battery life with ICS by turning data off overnight etc, however now with JB it seems to drain much quicker.
I'm only sync'ing the minimal essential things as before, pretty much exactly the same settings, so disappointed in the battery life.
I made a point of doing a full wipe both before and after the update to be sure of starting "with a clean slate".
Some people have said that battery life should improve after a few days. Why should that be? Is it busy housekeeping its flash memory or something?
Did you try Settings->Application Manager->All->S-Voice->Disable?
Works for me.
I'm the same. Ics was much battery. I have turned everything off, disabled everything unsynced everything and batteryvstill draining at 3-4% per hour, whats the point of a smart phone if you can't use it! My battery drains pretty much the same whether the screen is on or off!
I found battery life in JB to be poor IF my wifi was connected - with wifi off or just disconnected battery life seemed to be similar to ICS. I use wifi a lot though, so for the moment I've gone back to ICS... wifi range and performance seemed to be lower in JB too for what it's worth.
Im loosing 2% overnight using foxxhound

I get roughly 10-15% more juice out of JB with identical apps and settings.
My battery life is a lot worse on stock unrooted UK BTU JB aswell ... didnt even get 10 hrs out of it yesterday ... doing a full wipe and restore just now but its taking hours to put my apps back on ..
Didnt take this long to restore a iphone or is something wrong here ...My back up is only about 300mb and its been about 3-4 hours and still just at 50% complete ...
To be honest, that looks alright to me. 17 hours with network on all the time? And look at those wakes while the screen is off.
Post some BBS stats

i will hope that fix it when release the final version
If you guys having some battery issue or drain battery. I suggest you need to change your battery. Its not a firmware anymore. Because i also experienced this i purchased new batt then no more drain issue already.
Sent from my GT-I9100 using Tapatalk 2
Mine has notiably decreased. I solved a lot of it by freezing crap loads of apps and making a lot of adjustments with the autostarts app. One notable differace that I didn't expect was a few non-system files with 'test' in the name that was appearing under "Media" in the battery usage part of settings. I still have faster drain than normal and am not convinced I'll stay with this build just yet or not; it will take some days of testing. One good thing I noticed was that with a poor signal after being off of wifi for a big chunk of today, it didn't drain any slower than when I had a good signal.
The above said, though, about my battery life, I was previously also using autostarts with a heavy set of disables and had Dorminix with some severe tweaks. I actually stayed on AOKP as a result of better control over what ran actively (back button to kill maps for example) as the decisive thing over being on 4.04 prior to this release. Even on 4.0.4 I got worse battery life than the AOKP build that had the Earth and Moon aligned for my particular handset. Glad to have the Samsung camera back for the time being. Maps seems to draw WAY less than on the AOKP builds on Samsung as well, including this update.

It seems like a coincidence for a number of people to all have more battery drain, due to a dated battery, when they all go to a new ROM. Some people have issues, some people don't. It seems to me that its more a device specific thing than a mass placebo effect resulting from an update. I could be wrong though, since I'm partially making the assertion based partially off of my own handset and battery.
Battery not Charging
i have updated to JB 4.1.2, 2 days back but i am facing a strange problem. My battery is not charging more than 67% even charging for more than 5 hours. its becoming HOT and after 67% its not charging more .. it is OK on all other Stock and Custom ROMS.
Battery Life, in my case, is considerably better than under 4.0.4, and it's not even comparable to CM9 or CM10 that always died very fast on me.
for me its even better, i got 18 hours of battery and still 38 pacent left... 40 to 50 messages, 30 min of wify etc
I still got 23 hours, the lastest ICS version last for 27 hours and 17 minutes
So it's the battery is it?
"Stable" ROM to a test release and it's the worn out battery, which was fine on the previous "stable" ROM, that's causing the piss poor battery run-down?

Hi guys,
A couple of weeks ago, Note II informed me of an upgrade. I did a bit of googling and found out it was to fix some exonys bug. Seemed pretty important so I did the upgrade post haste.
At first the battery life was atrocious (like a 50% drop). The same thing happened with my old iPhone 4 but everything reverted to normal within a week. So, I though maybe things are new and Android will fix itself up after some time.
How wrong was I ? LOL. My phone gives me just a day's worth of battery life. Earlier it was a solid two days. Which was why I justified carrying this brick of a phone. It is pretty ridiculous to see the battery drop by 30% at times in three or four hours (despite zero use).
Any suggestions to improve or remove the pathetic firmware upgrade.
1. Use the nova launcer
2. Auto brightness with the slider dragged to 1/3rd
3. 3G always on
4. The battery screen shows screen taking 70% of the battery! I have the auto off timer set to 15s the minimum.
Any suggestions guys? I am frustrated with this phone post the update. Thinking of switching back to the iPhone as atleast it gave me a day's pf juice in a much pocketable format.:crying:

Honestly you can't do anything. In American english, you can't do nothing!
Turn 3G off, when you don't need it. Keep brightness at as low as possible.
That's all. 4.1.2 drains juice faster than 4.1.1, it's the truth, doesn't really matter if someone agrees or not.
You could go back to 4.1.1 ROM you know and depend on your luck for that Exynos issue. Otherwise give up on great battery backup and stay with 4.1.2, like I'm doing. Nowadays I don't even monitor how much battery backup/screen on time I'm getting, on 4.1.1 it was the opposite story however.
Hey, so should I just resign myself to a gimped battery? What really hurts is how awesome the battery was before.
Any word on when samsung would release a good update?

Download better battery stats to make sure there is no wake lock. I will advise despite my best efforts the battery life has plummeted when upgrading to 4.1.2. Stick to 4.1.1 for battery life. It still lasts much longer than an average handset saying that

After updating to 4.1.2 my battery runs down about 20% quicker overall I would say. 70% for your screen seems severe. Mine is always set to 50% auto and takes between 30 to 35% of the battery usage.

If you go back to 4.1.1.... Stock even....you'll have the same battery issue.
After about 2 weeks of having the 4.1.2 (the second update I received) on DBT my battery life one day just magically got better! I had been having terrible battery life (like 1 days worth) for 3 months, and now I get home every day from work with 50-70% battery. I charge it every night, regardless of the %. But it just magically got better. I'd say give it a go for a week or 2, and see if it helps. I don't know what happened with mine, but it looks like the software just "settled in" because I didn't install ANYTHING new, and in fact, I hadn't even uninstalled anything! It just got better after using it. Do a few battery pulls / restarts, too.
I went back to 4.1.2 last night and right now I'm at 50% charge, 17 hours standby time and 5 hours of screen time... I'd say my battery issue is fixed.. for now lol
I also must say that after a week or so of using 4.1.2 battery went much better overnight. I automatically turn on airplane mode during night, and on 4.1.1 I had like 1-2% drain overnight from full charge. After updrage to 4.1.2 it jumped to 10-20% !!! Now, it is down to like 4%, which is not that bad. Still have to see how it behaves during the day, I think it is not any better. Well, at least that standby drain is (much) better....

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

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 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?

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.

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.

So to summarise op. You have created this thread to advise people to turn off a few apps and turn on power save mode. Ingenious.

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

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.
