How much baterry usage when just staying connected to wifi?

[Daniel Szabadi]

Hi all,

I've been using my phone in a way that it disconnects the wifi when locked down (I have a data-plan so notifications are coming through edge usually).
And I've just realised that it's a bit annoying (actually no big deal^^) that when I want to check something relatively fast,
I need to wait a few secs (depending on the wifi, ~3-5 secs) to get connected again.

I wonder, how much more does the battery get drained when the phone is always connected to wifi?
Is there a "connected but idle" state?

Thx

I've started using my 928 with WiFi always on but I turn my cellular data off if im on WiFi and I noticed a huge increase in battery life im talking 20 plus hours
