Crazy battery drain after upgrading to 3.9, program to test?

I think my thread got deleted due to the crash, just reposting
I'm having crazy battery drain after upgrading to 3.9, about a percent a minute. Is there a program I can use to see what program is using all that juice?

The monitor function of SystemPanel is great for tracking down problems like this.
Also, if you're phone isn't sleeping, checking partial wake usage in Spare Parts will tell you what is keeping it awake.

Thanks for the quick response, I'll monitor usage for a day and see what comes up.

Have you checked your awake time vs. uptime in battery stats?

I think I found the problem, it was a corrupt copy of wireless tether that I had installed, the battery life seems okay now, still lower then what I was getting before hand. I'll post some screens here later. As for the uptime vs. awake time, I'm at 23:30:51 uptime vs 3:46:46 awake time, battery is currently at 43%

wow thats good, how do u get such good battery, i would normally only get 1:30:00 or something around there for awake time before mine would die, are u using set cpu?

I got...
32:48 up / 4:57 awake. At 37% battery.
I'm using the new OTA deodexed by Myn along with the new radio package (radio,wimax, pri, nv) by caulk. Nothing else! Set CPU is uninstalled. WiFi is on 100% along with background apps/auto sync. Mobile Networks only on when I am out of the house and without WiFi or 4G. I actually get good battery life on 4g if I keep the mobile networks off.

Here are some screens from my phone. This is after a normal days usage for me, do these seem normal for my kernal/ROM?
(This is without any type of OC/UC utility, I don't ever use those anyway)

How do u get better battery?

(TIP)Possible battery drain solution for LTE devices.

Like many here I've been having battery drain issues since the day I purchased the Galaxy Nexus. I also purchased the extended battery since day one. I've been reading through every single forum on how to reduce the battery drain and none seems to have worked for me. I've tried switching to wifi, 3g only, no email push, no google+, etc and my phone at 100% battery would lose almost 30% within 2 hours idling. Then I was looking at the settings and I came across the Developer Options/Background process limit and limited my background process from Standard to At most limit to 1 process and my battery has improved tremendously. Prior to making the change the Android OS was using 80+ % on idle (Wifi or 3g didn't make a difference), now it's uses around 20 or less. On idle I'm seeing around 4% or less an hour vs 15% battery drain.
Please remember this may or may not solve YOUR battery drain, but it has definitely helped mine and I just wanted to share with the community on what else you can try.

I've had pretty good results with my battery. I think some of ya'll are either just playing around with it too much or have some energy-sucking apps out there.

Or that you don't have a connection to the data network.
Just say'n. (I do the same thing at night)

I had Wi-fi enabled for 12 hours, and the battery only dropped to around 85%. I have been on 4G for 5 hours now, and the battery is now down to 13%. I'm going to use a Wi-fi/3G combination tomorrow. Oh and I also have my phone rooted/underclocked to 900Mhz.

I've been using it for 3 days and have had no issues. Anyways its as easy as checking the standard limit if you ever wanted to revert back.

Did I get a defective battery?

Just got my s3 like a week or so. I made a mistake and not charge it initially (thought it was a myth). I used my battery all the way to 17%. Now my battery only average up to 2 hours screen on. My sister who also got the phone as the same time has about right hour screen on time. Did I screw up or it's just my battery being defective
EDIT: attached is the battery stats

What's brightness set to, and what are you doing while the screen is on? You on WiFi most of the time?

Well, when I'm in door, I use low brightness most of the time. Only when I'm outside I would use auto brightness. Since I'm in wifi zone most of the time, yes I do have wifi on. I mostly use my phone for twitter, web browsing, and youtube, nothing heavy like gaming or benchmark.

Hard to say if its defective but I've definitely seen a lot better battery. It might not hurt to try and get a new one.

you should calibrate your battery a couple times once you get the phone. do it a couple times and it will fix itself. also check all your syncing settings. this phone will deplete a battery in 5-6 hours if fully charged and phone brightness is up all the way while watching videos.

Calibrating batteries is a myth from the days of older battery technology. Draining your battery to 0 on purpose is actually killing your battery faster because you just used up one cycle.

There's a bug on stock that makes cell standby much higher than it really is. So I wouldn't worry too much about that.
Also, Google Chrome is a huge battery killer for some reason. Consider switching to a different browser?

Still having the original battery in my vibrant and getting 8-9 hour charges while killing the battery 100% and charging it up once a week does nothing? Same thing for my g2x. I get about 10-11 hours on the thing daily original battery as well. If anything and you're not rooted to delete battery stats, its a good thing to do a couple times. I don't think I have hurt the battery at all, and if anything they still last very long...

[Q] Sharp and consistently high battery drainage

Hi, a few days after flashing ICS OrDroidX ROM from Android Revolution HD, I noticed that my phone battery starting to have sharp battery drop, for example after 30 minutes of off screen, it will drop from 97% to 92% based on the log from CurrentWidget. The current drain also extremely high, often stay between 300mA to 600 mA, rarely back to normal with 8mA draining in off screen.
I have done the wiping battery stats from the tutorial, and reflash CM10, however it get back to same battery drain though less severe than before, about 200mA drain on average, the sharp battery percentage drop still there.
Please let me know if there's anything else I can do, my phone is rooted, hence I would try to do anything I can before returning to HTC which I almost certain that they will charge me a lot for replacing a battery. Will battery overheating cause the issue as well? Thanks in advance!

I would say download betterbatterystats from the play store. It can give you information on what is active.

Does it ring any bell that something is wrong? I notice that the awake is somewhat a lot, is that due to kernel issue?
Thanks!

According to that graph, your phone hasn't been in deep sleep, ideally you would want to get a similar graph for Screen On and Awake. Go to -> partial wakelocks and give us a screenshot. Also, your signal doesn't seem very good. Do you usually get 1 bar?

Thanks a lot for the analysis! Yesterday I decided to reflash CM10 and remove all files from SD, and put them back after flashing. I get a similar graph as the previous graph that I posted.
After reflash
Partial wakelocks (because I did a reboot in between, so it shows only a short period of time, however during the screen on period of time, my battery have a awful sharp drop from 39 % to 29 %, a 10% drop in just a second...)
Shortly after I reflash the ROM and put my SD contents back into the phone, media scanner was a horrible process which hog on my CPU, after clearing the data from 'media storage', did several reboot then the phone only return to normal.
For the signal issue, my room never get full bar, normally would be stay around 2-3 out of 4 bar. Will this affect the battery life?
Now the problem seems like got two parts,
1. Screen off battery still drain quite a lot, though not as much as screen on
2. Screen on battery drain is awful, sometimes 5-10% in a just a second

[Q] Is the battery life real bad compare to G2?

Or is there any battery optimizations, both software and hardware that actually helped in giving more juice per usage? I'm thinking between G3 and G2 now and battery life is the deal breaker.

Came from G2, Z2, M8. This is the worst. Getting 3-4hrs SOT only at 60% brightness.

Yeah, I'm getting it sorta bad as well.. 3-4 sot on a daily basis... I find myself charging it twice a day lately.. But then again, I'm a heavy user.
On the other hand, my brother in law is getting 4 hours sot as well but over the course of 2 days... His usage is a low to moderate one.

The G2's battery life "out of the box" is significantly better than the G3. However, by using Greenify I've been able to get pretty close to the battery life I had with my G2. The deciding factors that pushed me toward the G3 was the ability to add memory via external sd and have a removeable battery.

Don't let them fool u. This was with 5+ hrs SOT. Rooted.
Scribed hence forth from thy LG G3
Or you can go the distance if need be
Scribed hence forth from thy LG G3

I've done a factory reset, tried zonerom, tried both kernels for the 851 and yes. Overall I would say about 30% less than my g2. Standby time is great, if not better than g2 but the sot time is significantly worse. I ordered a 2nd battery/charger so hopefully that makes this a non issue but kinda a pain to deal with.

Please post questions in the questions and answer section.
