Default Battery drain with wifi ON

I have enormous battery drain when wifi is ON, also when the screen is off and the phone is in deep sleep. I lose about 6% of battery without touching the phone. Tried different combinations of roms and kernels but nothing changed, how's it possible?

You have to check for the apps which are using wifi while it's on. Some apps, like Facebook, whatsapp, hangout, and many others stay on the background searching for Internet connection.. Another problem could be related to synchronization, do you turn it off when it isn't necessary?

Also, check in wifi - advanced - wifi scanning always available. And make sure it's off (on KitKat roms)

Maybe the fact that you actually played with the kernels so much, determined it to drain so fast. Go back to the stock kernel and you'll see the difference .

Try an app like Networklog to pinpoint the apps using your WiFi

Try this: uninstall trickster, or the different app you're using to set kernel values, then reboot the phone (it will boot with default kernel settings).. After that, reinstall trickster, then set your custom values..make sure you're using cubic as tcp congestion algorithm, (Westwood assures smoother data transfer, but it drains battery faster, especially while you're using mobile data, in my opinion..)

If you are on stock rom then DONT set "keep wifi during sleep - never,when screen is off,set it to alwayse since sometimes this command get stuck and will reproduce know wifi delay on sleep wakelock.

I do have exactly the same problem. Using CM stable 10.1.2 with default CM kernel.

Deep sleep is fine when Wifi is on (no wlan_rx_wake issues) but nevertheless it is draining like 7-8% per hour when Wifi is on...

Hey,
just like u i have the same troubles, the battery drain was the main reason to root and start with custom rome.
For sure some rom gave me better battery but finally i figure out that wifi has bigger battery consumption than 3G alone.
So i use wifi for big downloads or if theres no data network.
In normal use (music, internet, mail...) i never reach one day without charge d the phone.

ATM, am under the latest beanstalk ROM, wich is quite good, with wifi off last night, i've lost only 2% battery

U can also try this app: https://play.google.com/store/apps/d...octor_en&hl=fr
It was working quit good under 4.3 rome like slimbean or vanir i haven't tried under kikat based ones

Hope it helps
