Better Battery Stats
Start by installing Better Battery Stats:
http://forum.xda-developers.com/showthread.php?t=1179809
That will help pinpoint what is running the battery.

If you lose 10% in like 30 minutes, that means that whatever you're doing, you can do that for like 5 hours. That may not be bad at all, depending on what it is you're doing.
Of course, if you're doing nothing and have the device in your pocket or on your desk with the screen off, 5 hours really bad.

Can you explain how auto brightness causes battery drain, because that's new to me. I assume if I'm using the optimal backlight for the room, I'm using optimal battery.

If you're in a bright environment, brightness on the screen goes up with auto brightness
Manually set the screen brightness to low = less battery consumption

auto brightness doesn't even effect the battery performance. Speaking of "battery saver" apps, don't ever use those, it only makes the problem worse. I suggest don't use live wallpapers, end unnecesarry background apps, or just free the phone storage

Rarely going into deep sleep.

Hey, I recently installed paranoid android v20, (my first custom rom on this phone) and I'm noticing that my phone isn't entering deep sleep very often. Last night I rebooted to refresh everything and get fresh numbers. I plugged it in and put it in airplane mode. And this morning it showed 5 hours in 192mhz and only 1 1/2 hours in deep sleep. (I only slept for 6 1/2) any idea what I can do to increase the use of deep sleep?
More detail: I have my cpu set to 1350mhz max - 192mhz min, with interactive governor, using Kernel tuner.

You can go to settings, developers options, and make sure that " stay awake" is not checked. Because if checked it will prevent device from sleeping. Also check permissions on your installed apps and make sure they don't say prevent phone from sleeping. You can also try the app from the market called " Deep sleep battery saver " it puts the device into deep sleep when not in use. I think this will be helpful for you! Best wishes and hope I've helped you!!

Stay awake is off. And I tried that app before and I'm not sure if it worked. But I'll try it again. And how would I find out which apps have "prevent phone from sleeping" other then checking each app one by one? And, other then uninstalling, how would I disable it? Thanks.

You could install BetterBatteryStates.
It monitors 'wakelocks' which keeps the phone awake. You might find the app/settings to blame.

I remember now why deep sleep battery saver doesn't work for me. It turns off wifi at home, yet I need wifi for groove ip phone calls. So can't use it. I'll check out better battery stats, maybe that'll fix it. Thanks.

Okay, last night I charged my phone and left it unplugged with better battery stats monitoring. This morning I look and find a 22% drain after 10 hours, 9 hours in deep sleep, 1 hour awake. I checked and 44% of partial wake locks was Google maps. Why? Am I being tracked? Sheesh! So I used link to SD to freeze it until I need to use it. (which isn't to often as I primarily use Waze for navigation, maps is mainly for bus directions.) hopefully that will increase my battery life. Thanks!

Yeah okay, maps wasnt the problem its googles location service thats always checking where i am. So I disabled it. Hopefully that will fix the problem.

I have a similar problem, that is when I look at battery status plot under settings sometimes I see that the phone NEVER goes into sleep mode (always awake).
I installed BetterBatteryStatus and I see a lot of time spent under "partial wakelocks": mainly AlarmManager and Event Log Service. Any hint on how to solve?
Thank you in advance.

The guy who made the app is very responsive and a lot of the people there will help you. so, make a dump of your partial wake locks and submit it in the thread. you should also read through it a bit to understand others problems which may be similar to yours. see thread link below.

Battery Drops

Hi again,
If having a problem with my music effects in settings wasn't enough, I have a problem with battery drop too. It seems that when I reboot my phone, the battery seems to drop as you can see in the screenshot. I have deleted batterystats.bin and recalibrated using the app "One Power Guard" but that didn't seem to work :/ any suggestions? Cheers

Try switching to different kernel

Data dormancy is the big drainer, try turning on Stamina mode. As for kernel best to stay stock (if your custom). Also remove/disable unused apps.

Hello!
I think that this might help you: http://forum.xda-developers.com/xperia-l/general/tut-disable-fast-dormancy-battery-life-t2348597
That was the cause of battery drain on my Xperia L, some months ago, and when i disabled fast dormancy, the drain stopped.
You will need to have your phone rooted and buxybox installed.

Yep same here,phone app drain,since new firmware (15.3.A.1.17)
Fixed with above solution,with this rootkit http://forum.xda-developers.com/xperia-l/general/root-firmware-15-3-1-12-t2591290

Check which App is drawing battery uaing better battery statistics and look for any app causing wake issues! Disable them and things would improve !

Best way to turn off data connection or wifi when not in use
Use GSM
WCDMA when needed
Kill background apps
