Hi!
I tried to search for the solution, but didn't find one.
I've installed MIUI-NB ROM recently (unfortunately, I cannot post there, because I don't have 10 posts to post in developers' forums; if somebody can append the question to that topic, I'd appreciate).
Generally, I like this ROM very much, but today I have experienced HUGE lags when accessing the Internet via mobile data (especially noticeable on 3G). Load average jumps to 8 and more, lags are so noticeable that render the phone unusable. Did someone experience that?
Reboots do not help. Switching to WiFi cures the lags immediately, thought the load remains pretty high (about 2.5).
Did someone else experienced that and can give a bit of advice, please?
I did, I couldn't figure it out. I believe it has to do with either kernal or modem. Try miui LE 9.1 which is what I have with the kb5 modem and its super fast. I've haven't experienced any lag yet.

Its more likely do to the fact that he adds to much bloat and useless apps....hogging up all the ram.
I also use lithium with kb5 modem....can't beat it
Hey, i was a NB supporter, and loyal too, but it started to crash on me lately so today i went to Miui PRIME and so far.. its AMAZING no lag what so ever.
I heard Lithium was good too but i asked one guy and he said he got 8 hrs from light usage... so i was like ehhhhhhhhhhhhh
I was also on NB but it was too laggy ...so had to move on to lithium 9.1 ...which is working great
I had to go back to cm7, I started to get reboots during calls and had to take the battery out to shut it off. If i put the battery in it would fire up on its own. That was a first.
Ok here's an update I'm on LE 9 and I'm at 72% battery at 7 hours. Ill give you guys a total of hours when down to 2%.
This is with light to moderate usage, YouTube, FB, xda, web, texts and calls

Don't expect great battery life with any miui...I think the best I've gotten was around 12 hrs with lite use....I went and got cpu master and uv'd to 800 but im not sure it really helps but it definitely oc's very well

Battery usage isnt a huge prob for me, my problem is after a week or two ive gotta reflash the same rom, setup my apps. hate too but im thinking of flashing back to stock and running bionix. not having a stable build is getting frustrating.

How's the battery life on MIUI Prime? My phone, too, has been crashing after a day's use. I would have to restart it every 1-2 days in order for it to become responsive again. It gets annoying and I'm already contemplating on going back to 2.2 again. lol
Agreed I've been thinking the same thing.
Ok guys last update on my battery before I go to sleep. I'm at 6% battery left and it has lasted me 16 hours. I am using juice defender so that is helping. I used the phone to listen to music, FB, text, calls.

I was on bionix, and it was starting to drag and GPS wouldn't lock. so I wanted to try a newer ROM, just flashed MIUI-NB, but the low battery life worries me.
OK look at it this way....you know how your computer starts out really fast and all...then after awhile ....after so many downloads and websites visited it starts to slow down and then starts freezin up and all that....well that's what's happening to your phone,after all...it is a computer.
What I do is completely wipe everything including formatting system and SD and external SD...reflash your favorite rom and WHAM! Fast as hell again.
Thing to remember is all the BS you install and uninstall,isn't completely gone....its there and its hogging up your ram.
Just a hint guys... this rom your talking about is slap full of bloat alot of it is needed just to get fair results becuz of all the crap that's been done to it .
I'm back to 2.2 after almost 8 months of playing with miui and gingerbread,and I've realized something....the grass isn't greener on the other side.....especially when the proper files have not been released.
I do not mean to offend anyone...I am just posting my opinion off what I see after many many flashings.
I love miui with all the customizing that is made available with it but its just not what it could or should be and probably never will be and you can thank Samsung and T-Mobile for that.....unfortunately the vibrant is fading out as with the smartphone before it and the one before that.
One thing is for sure though.....the vibrant was the beginning of a Great Era. and that is a fact
After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

same here i upgraded to ICS xxlpq and have been using it for 3 days, im struggling to get a day out of it ... its exactly the same setup as when i ran XEU (KI4) 2.3.4 unbranded UK. I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
Hey friends I am currently running the OMEGA v28 4.1.1 JB ROM on my international GS3 i9300 and it is also rooted of course and I don't think I'm being paranoid but my battery life has took a massive drop since rooting my device. I am not overclocking mu CPU and I have tried out some rooted apps like battery saver for example and I actually think it made it worse. I have all the usual setting disabled to allow for optimal battery life like brightness right down, auto sync off, wi-fi off when the phone is locked I also only use the wi-fi manually if and when I need it and all that good stuff like smart stay and vibration off. I am wondering if anyone knows of something I'm not trying???
Had it charged to 100% this morning at 9PM and by 1PM I'm down to 79% already and I haven't made any calls and only used it to check my email and facebook for around 10 mins!!! is this normal for everyone else???
:crying::crying::crying:
Cheers

Sound normal for Sammy JB rom.
Some said Facebook is also causing the battery drains.

Did you reset your battery stats? Charge to 100%, reset battery stats from CWM or delete batterystats.bin -file, let the battery run out.
You might want to use currentwidget to log your battery usage.
I noticed big battery drop between 4.0.4 and 4.1.1 used to get 24 hours one charge 4 hours screen time. Now I get only about 12 hours.
Might just be me :/

I'm using also omega rom v28, have it installed recently. I cannot say how good is the battery with this rom, but so far I have like 56% in 20h, with 2h screen, sopcast 30min, voice cals 37mins....etc (also using wifi manually when needed)
Try out different roms and find out what works for you.
You can also use an app like BetterBatteryStats to check what's draining your battery. Its just to check whats use power.
Don't use batterysaving apps most of the time they are making it worse
I'm running Omega ROM V27.2 and yes it's normal to have a difference about battery life between ICS & JB.
To improve my battery life I installed the phenomenal extreme kernel, and now I'm totally happy with it. You should take a look to its topic in the GS3 Android Development forum. The dev developed 3 versions of his kernel to fit to most of the phone.
Also as others told you, you should get BBS app to point out the wakelocks & define which app is your problem.
Personally, I'm at 45% charged, and already used it during 21h 10m including more than 2 hours screen on. My auto-sync is always on and my WiFi only when I enable it. I'm using a live wallpaper and a lot Twitter.
When I do nothing I can reach more than 2 days.

Hallo,
I have the OMEGA v28 4.1.1 JB ROM flashed on Thuersday and i´m testing the ROM at a long time.
I use the Phenomenal4.0Medium Kernel and i must say the BatteryLife is very good. I`m working over 15 ours with him and i have 58 % on it.
My WIFI is every time on and Autosync when i use my calender and planners. For me a good app handdling battery life is "GREENPower" in Market Place.
But it´s my idea.

As he recommends ...identifying and reducing your wakelocks should be your primary concern. Been reading loads from developers that the insecure jb kernels themselves should already provide good battery management.

Hey guys, if you are going to use custom ROM's you should be prepared for bad battery. The developers are adding so many different features and hacking certain apps to make them work in their ROM's without a lot of investigation into what the reprecussions to battery are. I used to always use custom ROM's but haven't installed one in about 6 months and haven't any problems with battery life. I have the latest JB on my 9300 and battery life is very good. I use GSAM to watch apps that want to go rouge and start sucking battery life. Media Player Service is a big offender as is Facebook. Also stock widgets that get placed by these JB ROM's are always pinging for new data and kill battery quickly. Get rid of them! If you have a stock ROM and are getting bad battery, 99% of the time it will be bad apps, your job is to determine which ones they are and apps like betterbatterystats and GSAM work great to help diagnose the issue.
can anybody else confirm the above post? because i am not sure about the custom roms.
Sent from my GT-I9300 using Tapatalk 2
I will soon have an S3 so I cannot speak specifically about this device / ROM(s).
What I know from using a lot of Android devices and testing original ROMs vs. custom ROMs:
- original ROMs have too much garbage built-in apps and are slower
- original ROMs have everything working
- custom ROMs are much cleaner and faster
- custom ROMs have (too) much problems, something always not working 100%
- custom ROMs usually have stability & battery issues
My personal advice:
- install latest ORIGINAL ROM.
- root it
- install the free app "App Backup & Restore" from Google Play
- search unuseful apps from Samsung (& others) and block the autorun of these apps (note: do not block basic android or samsung apps, as phone, contacts, etc)
I use this method for 1.5 years and this way my Android is clean (you can save over 100-150Mb RAM), FAST and much better battery. Try it.
In the end, if original ROMs have too many original apps, custom ROMs have to many tweeks that in the end, for my taste, the original ROMs + App Backup & Restore win hands down.

I have always had custom roms on all my android devices but at the moment I am running stock ics in my s3.
I don't think the S3 needs it.
To be honest I find a lot of the stock based roms full of changes I don't really need, ARHD was a great Rom but recently has started to lag really badly for me (and some other users) so I went back to stock just to see and so far I can't complain. Smooth, fast and the battery is as good if not better than the custom roms.

Is anyone else getting Android OS around 50-60% battery use?
I have tried every ROM included going back to stock. I have ran the phone with nothing but Stock and no apps installed for a day and still get the same drain so I can only assume its a kernel issue.
I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.

I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals. I'm underclocked to 1350 and using powersave gov with deadline.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.
I can't speak for anyone else but FDT did wonders for my battery life. I was only able to go about 12 hours prior to disabling FD.

This is good for sure... it's just that compared to other phones, Android OS and Android System should not be that high.

^^^ This is indeed worth considering.... I think the question then becomes why is it consistent among the 3 roms we are using? Maybe when JB source is out and something is built from source all will be good.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.

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.

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

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

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?

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

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

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

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

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