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)

What's the rom/kernel combo for the best battery life?

State your setup, or the best you've had.

You're chasing unicorns with that question! There really isn't any combo that gives exponentially crazy super battery life.
With that said...
I think the best I ever had it was with:
ROM: AVA's Z3
KERNEL: Whatever version Netarchy HAVS no SBC kernel was floating around at the time.
I made it over a day a few times with that set up, but with normal use would make it about 19 - 21 hours.
I haven't had that kind of life for a while.

I have been on Fresh 3.5 since getting my Evo beginning of March. I use the stock kernel and would say I use my phone a moderate amount. Corporate emails pushed, Gmail, weather bug elite are always syncing, etc. When I have good reception, I can usually get 30 + hours on a full charge. I am not in a 4g area so I don't use that radio.

I wish I remembered my combo but I would get 60+ hours with light usage. It was dependent on setcpu + using wifi at home and work. I've been chasing it ever since I tried a different rom/kernel combo. I have gotten about 30+ hours with stock roms/kernel.

I'm on decks 1.2 with savage Zen and viperboys -75 script get 14-18hours of heavy usage. Lasts me all day at school with Pandora, music, web, some 4g... oh and I'm sixteen so I'm required to text my girlfriend constantly, so considering I leave at 8 am and my phone dies around ten each night. I get about 15 hours, light usage, no Pandora, a little music, little less texting, I easily get into the thirty hour range. as a general rule aosp roms get better battery life, and some kernels work different on different phones. Some people get absolutely ridiculous battery life with tiamat heavily undervolted.... 50 hours of constant use etc. Depends on your phone
Good luck
Edit: a few weeks ago I forgot my phone when we went out of town for the weekend. Three days gone, when I got back I had 37 percent left. Just unplugged it from full and left it on my table... then left, lol

Battery life

So far I've experienced excellent battery. I charged it fully when I got it home, and then unplugged it. Here are my results on an uncalibrated battery with moderate use except for when it sat overnight.

Good one.

My Photon can get me 4 hrs under the same conditions. Let's hope the battery will get better after a few recharge.

From A thread over at androidCentrel posting Epic Touch usage.
Tkemack
Screen On & awake look to be on roughly 70 - 75% use within 14 hr
Photon doesn't come close to such battery performance .
I'm looking forward to some Touch custom roms Battery life will get even better.

Im in debate battery life seems decent for me but no where near what other people are posting. I got 9hrs so far and im at 20 percent with screen on for 4 hours. Dodnt play any games just some web, text and xda. Does this seem right?
The first four hours the powersaver settings were still on. So wifi on, no 3g,4g,no auto sync,brightness at 10 percent.
Last five hours Auto sync is on. Brightness is 25 percent. 3 mail accounts with mail only and I've only had 1 email pushed the whole time. 4g off. Wifi only the whole time no 3g. Screen timeout 30 seconds.

Xperia S vs Xperia Acro S? - Battery-wise

Yeah, I'm curious on your recommendations on this subject. Which one of the two has a better battery life?...

The Xperia S has a smaller capacity battery (1750mAh vs 1910mAh) but the official quoted times are in favor of the Xperia S. Hope this helps, cheers

Thanks, but I've been looking more towards more personal reviews of the battery life.

I'm placing my Acro S in the charging dock every evening, before going to bed (23:00). Usually it still has about 40-50% battery left. I'm unplug it in the morning, at 7:00 AM.
As per usage pattern: I have 3 emails with push (work exchange email, gmail and hotmail). I'm browsing the net daily during my 30 minutes commute to work and from work (one hour in total). I'm listening music over BT - AD2P headset all this time.
Time to time I'm playing some games on it for 30 minutes or so ...
Some G+ (~20-30 min)
Some Talk (on average 30 min a day)
Phone calls - about 15-30 min a day.
Since I'm rocking my Nexus 7 for internet related stuff and gaming, I'm putting my phone in the charging cradle with ~70-75% juice in it.

Update, here is my battery history over few days (the vertical lines are at 12 hours apart)

My own xperia s on XTXperiance rom with advanced stock kernel does about 40 hours per charge, 4 hours of screen time. This is with 3G and data constantly on, hourly checks of twitter, 3 hours of music and some light 3D gaming (30 min) . If I use it very heavily eg. 2 hours straight of Dead Trigger with half volume, then an hour of Internet, it lasts a max of 5 hours. On calls it lasts rather long, 2 hours and I lose about 20-30 percent.

Sounds like your battery is bad. If you have the phone/battery for about a year or less, it's possible the battery is defective. If you have another battery use that one, but if you have a new battery you will need to cycle charge the battery. This means you have to charge from 0 to 100, let it deplete completely and keep doing the same thing for about 3-6 charges. This effectively breaks in a battery giving you the best longevity.

sorry to revive this thread but did a new battery work for you? I'm experiencing similar problems since the MM update, without fast charging enabled it charges at about 600mah, with fast charging enabled its about 1000mah but tapers off to 400mah once it gets to 85%
I'm not sure if its my battery or if this is a new "feature" of MM, last time that i charged from 30% it took 4 hours to reach 100% if anyone got a suggestion let me know.

3-4 hours is great compared to mine. If I use the USB cable, it'll take about 12+ hours (0-100%). Problem started after I dropped the phone. Luckily wireless charging takes about 5 hours.

Used to be no more than 2 hours before, not sure what the problem is, the battery is only a year old
