2.3.6 Kills the battery

Have not got around to calling samsung yet after complaining, but find that the battery dies a lot faster than before. I recently uninstalled juice defender to test and will reinstall under the new os to see if that had a effect. Any any ideas or clues to fix it?
Thanks

Did you re-calibrate your battery after the flash? Usually a good ideal, and it usually takes a few days for the took to settle in.

pretty misleading title.. 2.3.6 has been a big jump up from the older leaks for me. To each their own. I would re-calibrate.

2.3.6 had given me great battery life. I would definitely calibrate your battery either through CWM or the battery calibration app. Almost always after a new flash my battery is horrible until I calibrate.
Another thing may be... I previously had Juice Defender in the past. I found that it seemed to kill my battery faster than without it. The way the android operating system is set it automatically helps save your battery life. Most running applications get moved to the background and are using very close to 0 battery. For anything that I do not want running constantly I use titanium backup and freeze. It works flawlessly.
I do not use anything such as juice defender or auto task killer and get about 44 hours out of my phone overclocked to 1.3 with moderate to high use. Let android do its thing and you will be better off IMO.

Juice defender does help when setup properly. I've gotten over 100 hours of battery life using JD - though I'm still on 2.3.5

Check your battery stats to see if there are any unnecessary programs or tasks that are killing your battery life by running all of the time. Something that you may have had set-up or syncing differently since you updated.
2.3.6 has been giving me great battery life, I am running stock KJ6 with KJ6 Voodoo-kernel, no UV or OC, no "battery saving apps" and I'm getting 12 to 14 hours with heavy use, 30+ hours with light use.
Check this post

And the link on it...it explains how the SGS4G will automatically calibrate the battery under certain conditions, and how to go about it.

I never had a problem with the battery life before. On froyo it usually lasted all day with about 50% left.
On kj6 it lasts all day and about 70% is left at night.
I have no task managers installed and syncing with google, exchange, facebook, weather and couple other services.

How many here use Bluetooth? I usually use it quite a bit, but noticed that the new official kj6 uses an unusual amount of Bluetooth share (my battery life has dropped dramatically as a result).

yes I did.
I'm currently at 66 hours with 24% battery left. probably won't make it to 100 (4 days+) on this charge, but I have on more than one occasion.
I am a light user though, only some wifi browsing and wifi calling, along with regular calls, and maybe checking traffic every once in a while. I don't really use my phone for games or music.
oh, and I've never calibrated my battery or cleared the battery stats.

Cell standby: AOSP vs. Sense

Okay, I've been meaning to ask everyone about this for a while now. Has anyone noticed extremely high cell standby use in battery stats? The reason I ask is, when I am running a sense ROM it reads right around 5% usage. But when I am running any AOSP ROM, it usually between 35-40% and causes me to get really poor battery life. Has anyone else encountered this? Thanks for any info.
Sent from my HTC Glacier using Tapatalk 2

No, i have used both and havent really noticed anythiing like that. It may be just crappy cell signal, what roms were you comparing

I've flashed just about everything available for Mt4g except the ICS ROM's. I'm running team Inferno's arhd at the moment, but have in the recent past tried coredroid, tdj's sense ROM and a few others as well as cyanogenmod, MIUI, and some other AOSP roms too. I get great service in my area, and this has been an issue on all three mt4g's I've had.
Sent from my HTC Glacier using Tapatalk 2

I remember someone posting on here about sense or aosp roms, that you could open titanium backup and delete something called "Google Backup Transport" to help a lot of battery issue. I'm not sure if its related to what your problem is though..

Look into getting BetteryBatteryStats (http://forum.xda-developers.com/showthread.php?t=1179809). This will help you figure out exactly which process is draining your battery, as it isn't always Google Transport.
Also, this is a long shot since you said you have this issue on all AOSP ROMs, but have you tried changing the kernel just to see if that makes a difference? I know each ROM comes with a different kernel, but maybe there's a combination of ROM + other kernel that will work for you, instead of the default. I know that was my issue at one point.

On the AOSP Roms I always thought that it was normal for cell standby to be the highest battery drainer in the list because that's just how it was reported for some reason. I could never get the Display's battery drain to be higher than the cell standby. But either way I got the same battery life whether I used Sense or AOSP. The only difference was that AOSP just displayed the battery usage wrong.

+1...I do receive better battery life on AOSP tho, unless I debloat Sense. But the cell standby is always high on AOSP

I've tried most kernels that are out there, and still have the issue. I thought at first that the readings might just be different in AOSP vs. Sense. I usually let the ROM settle in for a day or two to make sure, but cell standby is usually double what display is in battery stats. I can literally watch the battery get crushed. Average battery life is about 8 hours on any given AOSP ROM and close to 24 hours on sense roms. I just seems like it should be the other way around haha. I really appreciate all the help I've received from everyone! You're all great!

Hmm, well one thing is for sure when your on AOSP and your in a area with bad coverage the battery drains significantly trying to connect to T-Mobile. Have you tried putting on airplane mode in those situations? It's what I do when I'm in school because I have literally no service there.

Did you try disabling mobile data when not using it? Or using juice defender where it would turn of data when the screen turns off?
Sent from my HTC Glacier using XDA

I've got juice defender plus. It adds around an hour and a half of life. The problem is, it seems that most of the battery isn't used up by data being enabled, but the phone being connected for voice and text. I'm not willing to shut off all radios for extra battery life because what use is a phone that people can't call you on?

Battery life ics

What ics ROM have you guys the best results for battery life? On AOKP, I'm getting like 8 hours with 20% left. I don't use data because it kills the battery fast.
Sent from my SGH-T959V using xda app-developers app

Prepare to be flamed for asking this question. Not sure why, but everyone seems to get their underwear in a bunch when this question is asked. Just a heads up.
Anyway, I had the same problem as you. I had the exact same setup as I did on CM9, but had much worse battery life, even after multiple fresh installs. I also don't have any widgets or many apps that sync very often. It seems that you just have to wait for the OS to "soak in." Make sure that you wait at least 10 minutes before doing anything after you flash the ROM. Just let your phone sit. After that, you can go into settings and tweak the phone. Also, try to go into the power saver settings, and setting sync to turn off after a set amount of time (I put 15 minutes), and for data to either turn off or turn to 2g mode after x amount of time.
Also, I'm sure you know the obvious.. turn off wifi/data/gps/bt/etc. if you're not using it. Set brightness to low or automagical.
I began with ~7 hours of battery life, and got to ~14 hours. Typically I don't have to be on battery power for 14 hours, and I tend to end up having ~35% of battery life after a full day of use.

Well I'm just asking how everybody uses their phone and hoe much they can get with it. Not saying that the battery life just sucks. I'm supportng my battery life with details
And i don't use many widgets either. I took off my live wallpaper too,i waiting to see how that works out

How is your signal where you live? Do you use your phone as a mp3 player? Have you seen this yet?
http://forum.xda-developers.com/wiki/Samsung_Galaxy_S/SGH-T959V/Why_is_media_server_using_my_battery
Not everybody will get the same battery life. If you are getting good battery on another ics rom and not another it is user error. Even if you are getting good life on gb and that kind of life on a ics it is a user error. Next time just flash and dont restore any data at all.

My battery life problems are pretty much not there anymore. I'm running AOKP M6B3, and getting 16 hours with 25% left, mild data usage, Facebook, GMail push, GVoice push, always on 4G and wifi on too.
I think the key was a Heimdall to stock, then to AOKP.

Yep. That's what I've been recommending to people complaining with battery on CM9 and AOKP to do. My battery life is great, and I use GR every time I go to a new build.

Well, to be fair, I went stock to AOKP M6B1, installed apps. Then just did an upgrade flash to B2. But still, much better battery life.

I'm running M6 version/beta 3. Gremlin remover does work but I did not do that I flashed over remics and doing great. I clear the battery stats and use all aokp features such as turn off wifi data when screen is off. I also have auto bright on and screen time out after 15 seconds. You also want to stay away from rebooting to much that will kill the battery and I also heard task killers drain the battery.

Look in your battery stats and see what is draining the battery.
I know there are a few ROMs that have the 'android os' power drain bug. I don't know the cause or whether a solution is being worked on. It seems the core of many of the ROMs are based on the same things. Kernels, modems, etc.
If it's the android os draining your battery start airplane mode, and then turn it off. Everything should go back to normal.... at least for a day or two.
I've run Zeus and JB-paranoid android. both has this issue. When i ran CM9 i didnt seem to have problems.

If it is not an issue for you, then upgrade to the latest build.
The one you are running is almost a month old now, so a lot of development has occured since then, specially at Scott's pace.
I don't guarantee it will solve your issues.. maybe it is one of your apps. But it definitely would not hurt to update, plus i'm pretty sure you will enjoy it

Battery life

This is probably one of the worst phones on battery life that I have ever had... No matter what I do, what tweaks I use of what rom I'm on... I always only get 7 to 8 hours of battery with 1 hr screen on time.
I honestly have no idea what to do... I'm so sick of it. Anybody have any suggestions?

Seriously?
I have been on my phone all day with a full charge and I still have about half the juice. I am on stock 4.0.4 ICS. The one that droidstyles has in his guide. The Rom that came with my phone sucked on battery. This Rom works great for some reason.

What are your settings on? Post your settings (like screen, whether GPS is on, ect), a lot of times it has to do with your settings. I used to have so-so battery life but I tweaked some stuff in my settings and am very pleased with the phone.
Believe me, if you want bad, try the Droid Charge. Worst 4g phone I have ever had in terms of battery life.

This is on clean rom. Ignore the screen percentage, going down since this was a recently flashed rom.

Possible Idea
Don't know if this problem could occur with different ROM's, but I had issues with a runaway process that kept showing up. Maybe try Developer Options -> Show CPU Usage. I noticed that one called gsiff_daemon kept showing up at the top and was making my battery drain extremely fast. Everyone on this forum said it was a common issue and that it wasn't a crucial file, therefore I should just change the name so it wouldn't get accessed.

On RLS7 and kt kernel? This kernel has capabilities for overclocking/underclocking & overvolting/undervolting. By default your min Mhz is set to 384. Go into ktweaker and lower it to 96, test your phone out with a scaled stress test (play store app for stress testing). Then you can also go into the extra settings of ktweaker and set the Mhz for when your screen is off in addition to the governor (many options of which some are powersaving labelled).
If you want to save more battery read the kernel's thread to see starting undervolting values and lower from there while testing your phones limits. More undervolted you are, the less battery your phone uses for that particular frequency.

You obviously never had the thunderbolt, now that battery sucked. You have to let the rom settle in and your battery will improve. Usually for me the first day not so good after that everything is fine.

I had a Thunderbolt. Yep, now that was poor battery life.
My S3 gives me 12 hours if I use it heavily. Typically, at 16 hours, I still have 40% remaining. I leave WiFi, bluetooth, and GPS on 100% of the time.
As bad as your battery is, I would suspect that you have a poor radio signal.and the radios are cranking up the power to work. Try using WiFi or turning off mobile data for a while to get the LTE radio turned off.

man, i barely get 8 hours at times

This. For example, I have a 4g tower nearby at work, normally (4-5 bars). But sometimes it disappears, and I end up on a 1-2 bar 3g tower for the day. On those days, my battery life is around 8hrs max, barely using it. On good signal, even with crazy heavy usage (4hrs screen on and lots of 4g web browsing) I can get over 8 hours.
Signal strength has a LOT to do with battery life.

Check your Google account sync - could be something in there is not syncing correctly. Settings / Accounts / Google.
I had this - Internet Sync was not working but kept trying burning CPU, network, and battery. Disabled the failing sync and all was better.

Is it switching between 3 and 4g a lot? Constantly searching is rough on a battery.

I seriously doubt you guys are getting 7 plus hours of screen on time with the stock battery. If you are then you are charging it at some point.

I am using stock battery on stock jellybean leak and get 30+ hours with 5.5 to 7 hours screen on time you can see from the pics above that we are not charging. The bar would go UP at some point if we were.
I just have my phone set up the perfect way to get maximum battery life.
It's simple. I personally have nothing to gain from lying about something so silly as battery life.
