So this 2 or 3 days I'm getting this kernel wakelock. Device isn't able to enter deep sleep mode and battery is draining fast. Can you tell me what is this wakelock and how to prevent it? See the screenshot.

Wakelock Detector show a list of what wacklocks been active.
The easiest way is to uninstall this app.

Hi all,
Is there any app to kill apps that are causing wakelocks above a certain amount of time?
I don't know if you experience this problem, but sometimes whatsapp goes into a wakelock called "fullsync" which basically knackers the battery. If I am lucky, I can detect this early and do a reboot
If I am not lucky, it just eats away the battery, major bummer.
Watchdog doesn't really kill apps if it is not using CPU power isn't it? This whatsapp wake lock doesn't use CPU power, it just sucks battery from nowhere
change Kernel mate.
Hello, I have installed BetterBatteryStats and CPU SPY, because I noticed that I had a faster than normal battery consumption when the tab was left alone.
I made a 30 mins test Wifi OFF, Flight Mode On, where the 29 mins of them showed me l2_hsic under Kernel Wakelock -> Since Unplugged.
Does anyone know what causes this and how to prevent it ?
Thank you.
( I am running Stock ICS 4.0.4 rooted)
Hello. I was curious about deep sleep and looked at the battery settings built into the phone: settings -> battery -> click on graph -> and it shows awake in blue. Is it accurate to assume where I don't see blue the phone was in deep sleep?

It'll improve battery life a little. But what drain battery is 3G and wifi and the service that prevent your phone to go to deep sleep mode while 3G/wifi is on. You can install CPU spy and wake lock detector to investigate what drain your phone battery and try to stop that service or remove it.

Thanks for ur reply...ok let me try with cpu spy and come back to u....but i have already installed wakelock detector...
I use Greenify to stop services from those apps that I am not currently using. When Greenify hibernates the app, it also hibernates the related service.
I did see a small increase in the amount of deep sleep and a small battery life improvement. Of course, your mileage may vary due to not all services waking the device.
Battery drain almost 10% in 6hr .when the phone is in sleep. screen off.
I checked apps are running (other than default googles ones)and even use greenify aggressive doze.
Using RR 5.8.4.
Even with setting CPU governor to powersaver .I still drain same amount of battery in deep sleep
Got any Idea why is that?
simply it don't go in deep sleep...something wake the device
Look Resurrection Remix thread. You need 3107 version with newest black screen kernel and power saver configuration.
