My OS is eating my battery up. What could cause this?

If you pay attention to your battery life, you'll notice that the OS is usually the second most battery consuming process (well it almost always is for me). That means that if your phone in your pocket for most of the day, then it makes sense for the OS to take up most of the battery life as the screen isn't on much. This was the case for me today where I had less than 1 hour of screen time on my phone so the battery consumption by the OS was higher.
----------------------------------------------------------
I noticed that there is another battery life for the OS, so I guess the Android System is things like the keyboard, nfc, etc. but the above still applies. Check the screen time and you should notice that it's pretty low.

Thank you. I didn't know if it was a software issue because usually, and ordinary day like today, the screen always took the most %

What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?
Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.

As the graph shows... Not connected to the charger yet it increases 5% in battery life, went from 29 to 34...

Same
Mine does the same actually. Everytime I look at it when its below 50% life it always has a part of the graph as it charged a little bit. seems wierd
The battery usage and percentage in the notification panel is more of a guess of where your battery really is based on usage. A lot of usage will cause it to guess your battery is at a certain level, and then less usage will lead it to believe your battery is at a higher level.
It also has to do with the charge going to the battery, but that's a bit more involved.

This is normal behavior for a battery, i've had this with all my android phones (HTC Magic/Galaxy S/Galaxy Nexus).
I have that too. But I believe Tesla hasn't died and is currently working with Google or Samsung on some sort.
Poorly calibrated battery or a big change in ambient temperatures?
For example here in Finland, it can be like -20'C outside during wintertime and the battery seems to take a hit when using the phone outside and after coming inside to +20'C (or more) it could suddenly (when warming up) load the battery magically
Mine does the same and I love it!
this is normal for this type of battery fuel gauge because it's based soley on voltage. and you pressed the phone hard during that steep slope, then went idle, and voltage tends to rise and bounce back up when in a relaxed state. when this bounce is large enough it moves the SoC as well. it's all normal.
Has anyone else had this issue of a huge battery drop when they restart their phone?

It has only happened to me when I restart because of the phone freezing. Im running an ICS rom.

It happens every now and then. What did you last change on your phone before the battery drop?
I just had one a couple days ago when switching to Calkulin's 1.1 ICS...after that drop, I recharged that night and the next day got 13 hrs or so with 54% battery still remaining. I think that, if you change your rom and then the drop happens after your next reboot, it just means that the original battery percentage was off and it's now corrected...
In short, I think it's nothing to worry about unless it's happening frequently.
my phone is stock and has been for quite some time. I like to power down sometimes to save battery or to not be distracted.

OP this seems to be a known issue... I asked a question along the same lines a couple of weeks ago, and had a quite a few responses. Here ya go:
http://forum.xda-developers.com/showthread.php?t=1520830
The only time this ever happened to me was when my phone would reboot on its own due to a system crash but when I would reboot it again manually the battery stats would be back to what they were maybe 1-2% less.
It happens sometimes. I believe it has something to do with the Maxim fuel gauge chip in SGS2 phones. Sometimes reboots throws the battery stats off, but your phone doesn't actually lose that much charge. I've actually seen my battery % climb after a reboot. Wiping battery stats usually fixes the issue, as does charging to full of course.
Brand new stock phone...is this normal?

Don't you WANT a higher "system" usage than anything else? That means apps aren't sucking much battery.
I mean, if everything else is using so little battery (WiFi, screen, apps) what is left for the remaining percentage besides the system?

Not really.
I had this happen yesterday. It wasn't that the others were using so little power. It was that the power used by everything else was dwarfed by the power used by Android System. In just under two hours my phone had dropped to 85%. When I looked I saw that Android System had used 45% of that. The phone was not sleeping even when the screen was off. I could also see that the Stay Awake time of Android system was nearly 100% of the time I had been on battery. Something in the Android System was stuck in a wake lock.
I tried to determine what the process was that was hung up but I was unable to do so.
I rebooted the phone and the wake lock went away.
Hey guys,
I've really liked this phone - until a few weeks ago.
I had the fated sudden decline in battery life. BetterBatteryStats has been on my phone for a while, so I opened it up and checked what usually kills battery on Android: the wakelocks.
It seemed totally normal!
Then, I checked processes. (These are today's stats, still just as bad)

system_server?
I noticed my phone was getting warmer whenever I was actively using it right under the camera, I guess which is where the SoC is. It's also been getting noticeably laggier.
Also today, under the battery usage in the settings:
Android OS and Android System are using twice as much battery as the screen.
This is pissing me the hell off. My phone drains perfectly acceptable battery when it's asleep, but take it out to use it and suddenly it's draining over 20% an hour. The extremely vague and obscure nature of the process doesn't help either. What does system_server even do?
I'm running Tweaked, and I've been alternating between ColonelX and Lean with no difference in battery.
I've also dirty flashed (really don't want to factory reset) to the NF4 Tweaked 3.5 beta. Only difference here is less lag.
As for bootloader, radio, and all that stuff, it's NF4 as well.
Nearly all Samsung bloatware is frozen in Titanium Backup, and all other troublesome apps have been greenified.
Attached is a log from BetterBatteryStats.
Thanks in advance for your help!
(I'm typing this on my phone, and battery had drained over 10% since I started writing this post.)
I had exactly the same issue since I upgraded my note 3 to Lollipop. It was fine when the phone was in sleep. But when using it, it drained the battery super fast...
system_server consumed lots of CPU resource at most time.
