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.

Battery Usage

Sup guys,
I was curious to know while actually using your charge how fast does your device drain the battery. I know it can vary depending on what your doing (video streaming etc) but lets use web browsing as a example. Looks like I lose 1 percent every 3 mins. Does this sound normal?

Last time I tried that it messed with my data connection and completely killed it to the point of wiping data...

You should be able to get 2-3hrs of screen on time per charge cycle. This is also dependent on what you are doing when the screen is on, and also how much your phone is doing with the screen off as well.

Which thing messed with ur data? The battery saver? I had that problem with other battery savers (juice defender, battery doctor) but no problem at all with AnTutus battery saver.

I go 100MHz-800MHz conservative, and almost all my apps run smoothly. If something like an intensive game needs more juice i go 1.2GHz and smartassv2. Ondemand is junk don't use it.
EDIT: I just went 12 hours 29 mins from full to completely dead (powered off) with 2 hours 23 mins of screen on, much of that was heavy web browsing (lots of tabs on Opera) and gaming.

going to try your setup. Any minor synchronized apps? Like weather for example.
Sent from my SCH-I510 using XDA

Interesting. I run TS1.4 w/ PBJ (no ext4) and I went through a number of settings and I could not get sav2 or sio to be lag free. The combination of ondemand and noop yields the best performance for me. Now if I happen to have 5 or more apps going then RAM becomes and issue and I have to march out w/ task killer.
I also 100/1200 for CPU settings, no volt modification.
Up until the latest google maps update last weekend, I have the sensor thingy killing my battery every few days, and that has seemed to clear up.
I also bought one of those extended batteries from ebay w/ 3500Mah and it is a beast (last 1.5 days easy), however a bad result of that is that it interferes w/ the BT and Wifi reception to the tune of -20db so it makes a marginal connection crap. It looks like the charge antenna is on the right, right next to the battery, and the beast sticking out is messing w/ the signal. I am going to try a few different materials over the battery to see if I can sort it out.
It is almost fearsome how quickly the stock battery drains...I mean if I am out work and going out until 3AM, no way it will last unless I use the beast.

Weather Channel, turned sync as low as possible to the point where there is nothing in my status bar and I go into the app to check it.

Also no latitude!! Make sure you are signed out of latitude in Maps and never open that app. It updates your location to google which wakes the phone and stuff.

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.

Idk why your battery life is so bad.
I have power save on, no vibration, and sync set to manual. That's about it. Battery life for me is amazing.

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.

Rooting is completely different . Not related with you battery juice.
1. So in case u want to extend your battery life switch off your data connection/WIFI when not in use as it uses most of the battery. When on 2G/3G battery drains like hell.
2. Turn of sync which also eats most of your battery.
As far as juice defender is concerned i personally didn't find that much of a difference using it. Set up is not that difficult either. Just install and use it. Not sure about the error you are getting.

hi bro
do as what i do in the pics
Settings=>Applications=>Mange Applications=>All=>You will see so many apps only the (chat,games,apps you downloaded yourself you don't use them at that moment )=>Force Stop
example:play store,yahoo,browser...=>Force Stop when you don't use them
After every restart your phone some apps automatically open again=>Force Stop
Data,WiFi,Bluetooth when you don't use them turn off them
some say black wallpapers use little bit less than color wallpapers pixels
don't use any launcher it use your battery so much because you run them
battery life apps it's all fake only you root maybe it will use less
(i use international stock firmware version it asia frimware and it's has so many apps from stock and automatically become open and it's not good eat my battery in bad way better for this to use some firmware that orginal with support of your country language and less apps)

1) turn off wifi/mobile-data when not in use. Also, turn off autosync when not connected
2) Use 2g instead of 3g when net speed isnt an issue .. most browsing/messaging will work almost the same on 2g or 3g ... 3g uses a lot lot more battery juice compared to 2g/wifi
3) Turn off automatic location reporting by google maps
4) If you do all above, you can save more battery juice by uninstalling all battery saving apps and task killers

Battery problems

Hello there,
I noticed that my battery really doesn't last long. It's been 100% full and now, 4 1/2 hours later, there are only 6% left. The weird thing about that is that I did not really used it during that time. WLAN has been turned on over that time, display was really dark, no backlight notifications or anything. Has anyone any idea how to fix this? (LG P940)

Thats not really much of a battery for the hardware,.. how old is it? Is this a recent problem, and when did you flash to CyanogenMod ?
To me it sounds like something is draining the battery pretty hard. Is the Wi-fi signal stable? Any processes under Apps>All, using excessive memory?

To me it sounds like you are having wifi/gps/bluetooth on all time, and if not, you should close ALL apps next time. Some running apps on your background could even drown your battery from 100% to 0% in less than 2 hours. Big apps or games cause the most trouble

If this phone/battery is more than one and half year old, this could be just battery dying, like mine (LG P920, 2 years old, 1500mAh) is dying right now.
It can't last more than 6 hours lately, so i bought a new one.
A li-ion battery (standard models) just can handle frome 300 to 500 charging cycles, thus if tou charge your phone every day, battery life has about 18 months lifetime.
After, it just dies, more or less slowly.

Thank you all so far.
Bought the phone 1/2 year ago so this can't really be the problem. The battery has never been great but got worse about a month ago. I flashed it about 2 weeks ago and this didn't seem to influence the battery.
I always keep GPS and Bluetooth turned off (only turning GPS on when I go running, but I never noticed that this influences the battery either) and Wi-fi is pretty stable. As I heard that Wi-fi is really bad for the battery I tried turning it off as much as possible and so far it seems a bit better.
I also took a look at how much memory the apps use and saw that Facebook, Kingsoft Office and Whatsapp really need a lot. I think I will uninstall Facebook and KS Office then and see if this helps.

Also problem with battery
I had a similar problem, my battery got "sick" after I used my phone as a GPS during 2 or 3 days. the phone was quit warm during the navigation. After that The battery life was reduced from around a day to 9-10 hours. In addition when battery is around 20%, the phone just shut down due low-battery and as soon I turn it on, as soon it turns off!
The solution was to buy a new battery, but that is odd that using the phone as GPS navigator damages the battery so badly!
Btw, my phone is a HTC desire w/ Android 4.2
