Default [Q] Wifi drains a lot more than 3G during deep sleep

After some time with my G2 I've resolved all my wakelocks and I've been getting about 3 days battery life with moderate usage. Which is great.

However, I've got one issue that's been unresolved. During deep sleep, I lose about 13% per night when connected to Wifi. If I am connected with 3G I lose 2-3%. Can anyone else confirm this?

Wifi should be a lot more power efficient, no?

I think this pretty much depends on the WIFI reception - if the mobile has to search for the WIFI signal frequently and the connection is unstable then it's logical that the turned on WIFI will drain the battery.

The signal is strong, router in the same room as the phone. No more than 5m distance.

hmmm that's strange then...

have you checked these two settings in the extended WIFI settings:
- turn WIFI off when signal is weak > make sure tu turn this off
- turn WIFI off ehen no internet connection

just guessing, but maybe these settings let your Mobile search for a (stronger) signal more often, even though it wouldn't be necessary....

It is strange. I don't get it.

I've already tried those extended wifi settings but to no avail.
