Yes wifi is disabled when you lock the phone. So you need to rely on 3G then.
Though if you download something it will stay on as long as its downloading even if you lock your phone.
Yes. But if you have 3G turned on that will kick in once the screen is off. Alternatively if you have the phone plugged in and charging then WiFi remains on.so...if I'm at home using wifi + whatapps and the phone get locked, i won't receive messages from whatsapps ? is it what you are telling me?
Remember, this is a Smartphone. And Smartphones use data. Just sayin.
With older Li-ion batteries it would have been an issue, but it's not anymore.I know it
It's because in my work i have WIFI, so there is no need to use 3G instead of WIFI, right ?
I most of the case i have a source of power when i'm using WIFI
but... i intend to get a Lumia 800 which has unibody closed, so no chance to change battery if it got harmed...
In my case the phone will be plugged all the time ( wifi environment).
won'tt hurt or reduce the battery life ? cause...you know...leave it plugged all the time it's not good to battery life, right?
