Recently purchased the T-Mobile Samsung Galaxy S2 and I flashed Beastmod v4.2 onto it. I'm experiencing a lot of battery drain, approximately 10% an hour with very minimal usage. I flashed the same ROM onto an identical SGS2 and the batterylife on that one is great. I've tried reflashing Beastmod but still getting the same issues. Anyone knows whats going on or how to resolve this?
How are you flashing it? Wipe everything and fix permissions?
Sent from my SGH-T989
I flashed it following the directions on the Beastmod thread in development.
1. Download it and place it at the root of your SD Card.
2. Boot into recovery.
3. Factory Reset then wipe cache.
4. Flash the ROM then wipe dalvik cache.
5. Reboot!
Beastmod is still 2.3.5, you should consider flashing one of the 2.3.6 ROMs and maybe updating your Radio to the latest , much better battery seems to come with the newer update ...

Why would there be such a large discrepancy in battery life though from one T-Mo SGS2 with Beastmod to the other? That's what is making me scratch my head.
Did u do a battery Calibration? If not this might the reason why

Umm yeah that too ... duh ....
There is a BIG change in 2.3.6 in battery life, at least what I am seeing and others have reported, some say it is the ROM some say it is the radio , I am using both, I get better battery life, but overall the SGS2 Hercules is a battery hog ...

I have done a battery calibration on the phone.
Disable sync for your Exchange email. I found that to be the biggest source of drain.

I feel the same way my man..no matter which ROM I use, my battery drains like a mother
A lot of this can be due to signal strength. If you're in an area where you're constantly disconnecting/reconnecting to the towers, or you're just below the acceptable level for 4g, it might be switching between 3 and 4g, draining your battery.
Another thing to note, you usually want to run a rom for a couple of days before you start judging battery. It takes a while sometimes to build the dalvik-cache, and calibrate the battery. Sometimes as much as 3 full charges.
Lastly, look at what you have running on your phone. If you've tried tons of different roms, and they all drain, chances are it's an app you have that's misbehaving causing wake-lock. I'd try downloading system tuner from the market, and first going into the startup section. Remove ANYTHING that doesn't need to run in the background. You'd be amazed how many apps run at startup that really shouldn't, at least until you start them yourselves. Battery spy and cpu spy can be useful for troubleshooting what's draining your phone as well.

Thanks for the tips. I didn't give it a chance to do 3 full charges yet and I'll take a look into removing startup apps.
From the OP, it sounds like you have more than one SG2 phone available to you. Try swapping batteries to see if the same rapid discharge occurs where transferred.

I did try this but the issue with the draining is still there.
Have you tried changing kernels? Each phone responds differently to kernels and like some more than others. I've tried everyone and Faux's "stock" kernel works the best on my phone. It's UV, on stock speeds with a screen off profile.
To make sure your phone is actually going into deep sleep check the app CPU spy on the market. it'll tell you what clocks your phone is running through and staying at for the most time.
Also, check out System Tuner to see what rogue apps could be running constantly in the background [se Bloatware Freezer to freeze or remove apps as necessary] as well as if your 2nd core is staying offline and not staying on when it's not needed.
I would also throw your phone into airplane mode and compare the drain with no data activation to how you normally keep it to check if the 3G/4G toggling is draining your battery.

I've done everything I know to do to help with her battery life. She has a hardware 0003 Evo, the exact same as mine. Both of us have Sprint Lovers ROM with PRI 1.77. I have Netarchy 4.3.4, she has 4.2.2 because 4.3.4 didn't work well on hers. The only real difference between our setups is mine. I have Titanium Backup with most of the useless apps frozen and UltimateJuice with the latest JuiceDefender Beta. I also use LauncherPro.
I've noticed that her device pulls high mA's when discharging. I believe I saw one over 1100mA earlier while looking at something on her phone.
I realize that my setup may be a bit more battery efficient than hers, but her drain should not be as high. She literally has to plug up several times a day, when I can go 2 days on a charge.
So does anyone have any suggestions? I really don't want to have to swap out her phone.
you should try nets 4.3.2 cfs havs less, or the no havs those are very stable and great with battery life, before you flash fill battery wipe caches and battery stats, flash kernel
Try installing the 4.3.4 kernel again but play around with the versions. Try a less-havs if more-havs doesnt play well. Maybe even no-havs. Try installing juice defender on hers also and see how well it plays out.
Update her PRI. I run the most up to date pri and don't have any battery problems. It's probably that I can almost guarantee it. Some phones work better with different set ups then others. To update you can use caulkins flashable update zip. Its in the dev section in the first couple pages if you don't feel like searching. Just be careful when flashing.
get a 3500 battery, or maybe her battery is defective. You're a sprint service technician? come on now

Well, I'm not versed on sense kernels, but perhaps try a less aggressive havs kernel on hers. Does he keep her 3G on all the time, cuz that'll be a battery drainer.
What she could do is change roms, or if she's willing to, try out AOSP.
Calibrate the battery.
3500!! is the answer. You can't do anything with the stock battery. Does she give it a full charge often? My girlfriend only charges were phone a few hours each night and complaines that it dies often... and thats with the 3500... Even if the light is gree and it shows 100% done, its not really done. Let that thing charge for 8 hours straight. Google Bump Charging... that helps too.
In addition to all things suggested here, never underestimate the power of turning off auto-sync and background data. I keep background data off all day and then turn it on for five minutes or so every night to check gmail, etc. If your gf is anything like the girls I mess with then she's probably just killing her battery by updating her Facebook status twice an hour and tweeting every time her cat farts. Not much you can do to help if that's the case...
Social mongers pay for their insolence in battery life. For the rest of is, there's the background data toggle

Actually, she doesn't, so I'll probably end up doing that. I tried her on CM7 but she didn't like it, gave her more problems than usefulness.
If she's not a big background data user then you should definitely toggle it off. With comparable usage, I typically get twice as much life-per-charge with background toggled off than on regardless of what ROM or kernel I'm running. It's the biggest little thing you can do.

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.
Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.
biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.
I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).
Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)

2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.
The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)

Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.
Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.

I have a ROMed Galaxy Note 2 and the battery life is amazing. My son on the other hand has a stock Galaxy S3 and it's the worst battery life I've ever witnessed. It's the typical draining while in standby issue reported by many S3 users. Bottom line, his phone is getting a ROM tonight before this phone melts down. Problem is, which one do I choose? There are so many and it would take me months to read thru every post to determine which one is right for him. So for now I'm going to focus on what really matters most, battery life.
Which ROM have you read about or used that you feel is battery life winner?

We are lucky to have MANY great ROM's out there. There are so many great devs here that go out of their ways to make the experience better. I highly suggest trying as many as you can, because each phone, after much experience with my ROM's, are different. Make a nandroid backup and try a bunch! What I'm getting at is that there are too many well made ROM's here to pick one. Flash away. Oh and make sure you turn off google now cards and locations...that will drain your battery like no other on this phone. Best of luck!

I'm on Slimbean 4.2.1 RC1 with lean kernel and I have to say it is buttery smooth and stable, fast as can be, and I'm almost two days into it with ~45% charge. Loving it
For longest time I was swearing at CM10 / CM10.1 and than I found a thread about what affect battery and now both TW and CM based roms that I use are about the same...
To get great battery life follow the simple rules:
- stay away from colour. The darker the theme / icons are the better the battery life. Some go as far as to get inverted gapps...
- no live wall paper. It will affect battery life... yes, the darker the wallpaper the better the battery life...
- turn off GPS , bluetooth , nfc and everything else that you don't need... turn it back on when you need it...
I have 15 toggle mod and I even turn off data when I don't need it. (I turn it back on once every couple of hours to get e-mail and notifications... than turn it back off... this also prevents rouge apps from dialling back home to mothership...)
- if I travel from one location to the other I toggle airplane mode on and off... this forces modem to look for strongest tower... the strogner the tower the less power you need... hence less battery consumption...
- Use Ti Backup on roted rom... unistall what you obviously don't use..
- Google apps that run that you don't know what they do... stop or unistall those that you don't need...
- Use fierwall... block everything that doesn't need to talk to internet ... less you use antenna longer the battery life...
Also, if going to new ROM wipe battery stats and let battery fully discharge couple of times. This helps as well...
Follow these simple rules and don't be surprised if your battery life doubles regardless of the rom...
Cheers

While most of this makes sense, I have to disagree with discharging the battery fully. This actually reduces battery life drastically.

I agree but idea is that you let the kernel optimize it by itself.
So you do this only a few times on new rom and that's it...
As for myself I tend to plug in the S3 to charge as soon as I hit 60-70%...
(whenever I can of course - i actually keep one charger at home and one at work)
SIDENOTE:
Forgot to mention the widgets... to me they're just short-cuts and if you set them for automatic update (weather being prime example) they'll just waist battery and bandwith... (it takes about 1 sec to turn on the data from 15 toggle mod and 1 more to start the app I want updated - email weather whatever... to me this is a small price to pay for extended bat life...)
If I may toot my own horn, how about this guy getting four days from one charge with my ROM and ktoonz's kernel? http://forum.xda-developers.com/showpost.php?p=36384974&postcount=95
Your mileage may vary but I usually get about a day and a half or two days from one charge with the stock kernel that's included in the ROM

Auto update widgets kill my batt life also!

Hey guys I'm kind of new to the rom world and let me say i LOVE IT. So much stuff you can do with the android. I'm on a i747 galaxy s3 and I've just downloaded the Pacman rom.I've downloaded other roms so i know i flashed this one correctly. I even re flashed it again last night. Both yesterday and tonight my battery went to 100%-%50 in one hour. After i charged it up it would decline 20 percent in one hour. I look at the time screen time on and to see if anything is waking up my phone excessively. And all sings say to no. Any tips? I feel like I'm back in pre ics days haha.

when you flash a new ROM it is recommended to wipe Cache, Dalvik, Factory Reset and System. If you've done that you should be okay with the installation portion.
Have you modified the kernel at all, have you over clocked anything?
Go to the play store and download BetterBatteryStats. This will help you determine the cause.

Yeah i have. When i installed i did the whole wipe thing. And I'm useing gsm batter monitor. All the readings are normal which is the weird part to me. And no i haven't over clocked (No need to imo) and haven't modified the kernel. I know that on previous androids you would have to do a wipe batter stats. I actually tried looking for that in CMW but i wasn't able to find it. Would you have to wipe the battery stats using "batter calibration" or wiping it manually in CMW? Or is that even necessary for galaxy s3s?

I would also recommend using Better Battery Stats as it is the best one I think. I always use the battery calibration app after I flash a new ROM. It usually takes a couple days or so anyways to have the new ROM settle in and everything. After a couple days you should see your battery life where it should be and not draining so fast depending on what your settings are.
Battery calibration is a myth and has been confirmed by Google themselves. Its all over the forum and wholly unnecessary. Those apps are useless. The only way to truly let your battery stats "calibrate" is to let the ROM and kernel settle into the phone after a few charge cycles.
Here's the Google+ discussion by one of Google's people: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
If you want to keep "calibrating" your battery for the warm and fuzzies, its your time and device.

Wow thats interesting. Everywhere i go people say that battery calibration is a necessary part when switching roms. Just out of curiosity what do you do for better battery life ? Basically what you use and not use settings wise.

Everyone's battery life varies. Honestly, it doesn't matter the ROM. The kernel does play a part in it but its how YOU use the phone, display brightness, sync, etc. Way too many factors.
As for me, I get about the same life on most ROM's I use after letting the phone settle for a few days. The only constant I have is the kernel I use which is in my signature. Lately, I've settled on one ROM as the dev is on top of his game with this device. That ROM is also in my sig.
