I've had this battery problem before and then it suddenly went away, and now it's back once again. I posted this in the captivate forums and got no luck. I've searched on google multiple times and found no solutions. Just recently, my captivate battery has been draining very fast. I've been going from 100% to 0 in about 8-12 hours. The main battery consumer is Android System. There are no processes that are keeping the phone on according to BatterBatteryStats. I loose about 7-8 percent every hour while it is in idle/deep sleep. If I enable the extreme setting on Juice Defender, it bumps up the battery life to about 45+ hours. But if I use juice defender, sending and receiving mms is very difficult. I tried it on another spare battery and it gave me the same results. This problem started earlier this week and was present when I first flashed a ICS rom back in June and hasn't gone away yet. Does anyone know how to fix this problem? I did not change any settings or flash anything new to my phone. One day it suddenly went from 100% to 40% in 5 hours and after I rebooted it dropped to 5% in a matter of minutes. I recalibrated the battery but that did not do anything.
Your battery might be going bad?

Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.
Wiping battery stats in CWM does reset the battery useage screen.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

Thanks, I logged out already will report back after some time
I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?
try wiping battery stats in recovery with a full charge
I did a search and found similar threads, but it seems that my problem is slightly different.
I have been using different CM9 Roms over the past few months and they have all been pretty stable, and the battery life has been pretty good.
However, I was on a trip last weekend and all of a sudden, my phones battery went from 100% to 40% in a matter of hours with the phone screen completely off.
I tried flashing other ICS ROMs, installing the blue sleep fix to no avail (wiping in between each, even doing a fastboot wipe as well). Then I restored a nandroid I had of a CNA ROM where I knew I wasn't having any battery life problems, but the problem still persisted.
I installed better battery stats to see if I could get an idea of what could be wrong. For example, this morning, my phone was charged to 100%. I took it off the charger, and it literally sat on my end table for 2 hours. I didn't touch it. I then looked at it, and it was down to 80%. I went into better battery stats, and it said under the partial wakelocks that the longest wakelock was only a few seconds. I then looked at the processes, and it said that deep sleep was the dominant process at 1 hour and 45 minutes.
Obviously if the phone is in deep sleep it shouldn't be dying that quickly (I would assume). Is there anything that anyone knows might be wrong with my phone that it is killing the battery across all these different ROMs?
My only other option is to completely wipe the phone and sd-cards and install nottachtrix, since I was getting 2 - 3 days of battery life on that ROM.

Have you tried the app CPU spy on the cm9 ROM to see what's eating at the battery CPU wise and to see if your getting deep sleep?

has anyone else suffered from this this is the 3rd time this has happend to me in 2 weeks i leave my phone charging overnight then take it off when i go to work so its at 100% charged then the battery has been draining really quickly this happend to me on tuesday and again today on tuesday it was at 20% at 11:30 am i take it off charge at 8:00 am and today the battery is already below 50% and its only been 2 hours since i took it off charge keep in mind i hardly use my phone at work and the days i do use it more than usual i still go honme with a battery level of around 50% when im off work wondering what can be causing this or do i have a faulty battery??
You got something killing your battery way too fast. Take a look at what you have downloaded/installed. Try wiping it clean and install everything back, one at a time to find the problem. I'm using Freeza's ROM and kernel, getting a full day of moderate usage and usually ending up around 50-60% by bedtime.
You in a bad coverage area?
Have had this phone for about 2 - 3 weeks. Starting yesterday, I noticed the battery draining abnormally fast. I am not using any email client other than gmail. So basically, nothing in my routine changed. I didn't install any new apps, or started using any apps that I wasn't using before. Essentially, out of the blue, my battery is draining like crazy now. I had to recharge it mid day yesterday, had about 30% left before going to bed, woke up and phone was dead.
This is the s6's battery..i go out at 8 and at 12 my phone shuts down..buy an external pack and youll be fine

The reason I made the thread is because the battery was fine for me until a couple a days ago, now it drains 30% over night and I can barely get through half a day on light use. One problem after another with this phone. I guess I have to do a factory reset.
Booting into safe mode could tell you if the fast drain was caused by a rogue app.
