post some screen...i would see

No noticeable battery drain. Goes one and half day. I am not music and video guy, but 3G, emailing, sms, calls, wifi, etc on most of the time.
I disabled some bloatwares in app manager. Disabled MLT (lg log app) from hidden menu.
I use Advanced Task Killer, which stays in memory all the time and kills other unwanted background apps EVERY HALF hour in CRAZY mode.:good:Works perfect on all of my androids since last three years.
I also use Smart Profile which Automatically, Darkens screen to 20%, starts silent profile, switches off 3g/2g data, BT, wifi, etc all at 11pm automatically. In the morning the profile automatically changes back to normal at 7:30AM.

totally useless use of task killers. I'm surprised at you

I think battery drain can be related to Media Scanner, it consumes a lot of cpu time and takes longer on my 32gb microsd.
I disabled its autostart and battery life is still good on Jelly Bean.
Do you see it in battery stats?

i see in Kernel Wakelock -> PowerManagerService and wlan_ctrl_wake, the most
and Partial Walelock -> NetworkLocationLocator of Maps, but disabling it, Google Now maybe not work

Respect your opinion. I am nuts. No surprise.

---

no battery drain found
instead, the battery life becomes greater :good:

---

I also noticed much less battery life on JB. Even with similar use, hard to get 1 day out of the phone now (with music, fb, wifi etc), while before by the end of the day I still had around 30%

Yep I agree.
In android it's not a good idea to use a task killer.

Same here now i have 1gb ram. Okay 768mb stupid system eats 200mb+ but never less i dont use a task killer. It killes te ram it self doesnt lag. With my old lg o2x wirh 512 mb 380 with ram hack i used task killer other wise always lags.. but now nen is okay

---

AW: Jb battery
JB L9 has its own Taskkiller, so i've activated it, set to once per hour, lowest value.
And battery drain seems to be higher here, too. Maybe there will be some bugfixes in the near future, so currently no root for me.

---

I noticed battery drain, too

---

Problem is there is not a valuable reason for battery drain. We need to understand why with new jb there is battery drain. Hoping in an official fix by LG obviously.

---

As per my observation, I think main cause of battery drainage in JB is media scanning service wich runs too slow and consumes lots of battery. After stopping this service from running services, battery percentage stops getting down. But i am unable to freeze this service. One more reason to freeze this service is that we can't use any stock app related to media while media scan is running. I even don't know after freezing media scan what bad thing can happen.
