Any idea why my battery would drain about 49% overnight? I attached a screenshot of the battery usage
My battery has been crap the past 2-3 weeks. Right now, it's down to 42% in 9 hours with 53 minutes SOT while on WiFi w/o BT. I was getting 2-3x better than this until recently. No new apps installed. Could be an update, but battery stats has Android OS as the primary culprit.

since this weekend when i start noticing my average charge got me about 8 hour of battery life with barely any use. I've flash and updated my phone to Twin rom by myn and flashed the collin battery script. Took the phone off @ 5pm and now it 9:39pm and im @ 0% in 4:39 hr i burned through 100% battery with the phone on idle.
40% Cell usage (Time with out signal 0) allways full bar
34% Idle usage
22% Android System
4% Display
I am running CM10.1.3.1 with the nitest 7/20/2013 kernel and FC19 modem, on an Onite 1900 mAH battery.
I used many of the tips in this post;

10 hours overnight with minimal usage, my battery now drops to 78% and shows 4 days 15 hours of similar usage before the battery will be drained fully. I've never, since buying the phone new, had better than 26 hours of stand-by time show up with a fully charged battery. I'm now showing 5 days.
Of course, screen usage is still the big impact, so actually using the phone drains it just as fast, but it is nice to know that, if I am not using it, I don't have to keep it plugged in all the time now.
I could be completely wrong about this but...
Have you been rebooting your phone? From what I've read rebooting the phone can throw off the battery stats. Basically the battery storage and usage is all the same its just the reporting thats off. I'm guessing battery stats get readjusted over time if the phone remains powered on.
I noticed about 3ish weeks ago that my battery was depleting at a faster rate than before on my GoldenEye 4.2.2 ROM
Here's where it gets strange...
Regardless of my screentime I think that my battery depletes the same...right now I have had 56min on screen time and my battery is 48%
I tested how much time I could get out of my phone, and I can go from 100% to 0% with about 4ish hours of screen time....
I seriously feel that I'm getting more efficient usage by having my screen ON rather than off...
Here's my stats right now
Screen: 37% 56 minutes
Cell Standby 25%
Media Server 15%
Device Idle 7%
Skype 5%
Android OS 4%
Android System 2%
Seriously, whats going on? why is my battery being depleted so much with so little screentime???????
It's something Google did with the new update of Google services. No one knows exactly what it is tho.

I'm having 3 hours Screen-On-Time, and while I think it's "acceptable" I read about some people with 5-8 hours of SoT. I was having some problems with battery drains on Ressurrection Remix and Temasek and the best rom I found for me was Purify. With it, I don't get crazy battery drains and I finally had 3 SoT again, but I find it strange that on the battery usage chart the screen percentage is closely followed by the Android Operating system, not only that, Purify's developer said that he can get 8 hours of SoT (For me this is just impossible).
I'm using Better Battery Stats and GSam battery Monitor to check but there are some stats that I don't know how to interpret, as I don't know if it's normal system usage or a wakelock.
Thx for reading and thx for helping.
Call me crazy, but after the latest updates I got heavy idle battery drain. Same apps and use, I only could get a maximum of 2-3h SoT.
So I thought I would install GSam Battery Monitor to monitor the battery drain, and guess what? I suddenly got 6h SoT again... Wierd...
I uninstalled the app and tried a new full charge with the same amount of use and got no more than 2-3h SoT again.
Today I decided to install it again and now I have 46% left with 3h 10m SoT.
Am I crazy or what?
