I have flashed numerous kernels some of which people claim to get 15 to 20 hours of battery life with 4g on. I still can't achive good battery life with moderate use every 4 minutes of use my battery life drops a percent.
Sent from my ADR6400L using XDA Premium App
well for myself, I prefer the smartass governor, but not all kernels come set to use a governor that achieves battery life like that. They may come preset to ondemand, performance, etc. Some governors need to have profiles set to keep the clockspeed low while the screen is off. I am using adrenalynes 2.0 kernal still (haven't had time to flash his new one, will be doing that in a few) and Set to the smartass governor, I am at 22 hours, with 43% left, while running the tesla coil rom.
and oh, cause I love making people tell me it is a waste, I have a task killer set to auto kill every 30 mins...
When my phone isn't on, my battery stays up in the 90 s for about 2 hours... So on and so forth
When I use it its a different story

Yes I am familiar with smartass and so on i've flashed so many kernels. It's seems like I get good battery life for a few like taking 2 hours to drop 5 percent with use but after a certain point it just drops quicker and quicker

I like all the kernel tweeks, but the extended battery is great.
install current widget, and log your idle power draw readings over a few hours. that's the only way to see what your phone is doing with the battery. then i use system panel monitoring to see the highest used apps of CPU percentage, and deal with those accordingly.

you make sure to bump charge your phone and then wipe battery stats everytime you flash a new rom?
i noticed CWM doesn't seem to wipe battery stats, so I went in and wiped them with root explorer myself. Renamed the file to batterystats.bin.back and rebooted and have had nothing but super perfect battery since.
/data/system/batterystats.bin
nosympathy-
So I assume that the batterystats.bin file is automatically rebuilt (new file) after you rename it? Do you have to restart the phone or anything? What about if I don't bump charge? Will this still help?

My battery meter almost never goes down... started doing this after flashing BAMF remix, then i reflashed..no dice. Sometimes ill see it drop by 2-3 percent at a time.. sometimes 1%, after like 30 minutes or so, but with constant usage and 4G on this shouldn't be possible.. Could my voltages actually be getting me better battery?
Here is all I use, running Bamf CF 2.0 kernel (ignore my signature)

768 875
1024 1000
Also rebooting drains about 3-12% of battery at time... give or take.

The same thing is happening to some people, including me, in this thread:
losing about 5-10% battery on reboot
Someone suggested bump charging and wiping battery stats, but that hasn't fixed the problem for me.

If you're on the standard battery then nothing is wrong, that is common.

Use wifi as much as possible. Shut off data when not using. Don't use 4G unless needed. Minimize screen on time. Turn off autosync. Switch to a different kernel, etc. Juice defender really helped me, also. Make sure you set your CPU to minimum when screen is off. Two days probably isn't realistically possible with the stock battery, but you can probably get more.

Sounds like an issue with the software, more specifically the kernal. Are you rooted and running a rom/kernal combo? If so, try reflashing. If that doesn't work, try a new combo.
I've found a happy medium that I can live with... getting anywhere between 10-16 hours with around ~2 hours of screen time.
Running bamf stripped 1.7 using its stock kernel with the smartass governor and underclocking to 368/245 when screen is off.
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.
Sent from my SGH-T959V using xda premium
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.

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).

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.

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.

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.

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.

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.
