Do you guys turn off WiFi and mobile data when not in use?

Recommended Posts

If you have bad LTE reception or WiFi not connected to anything, I personally do turn it off because it has a noticeable effect on battery life for me.

Your mileage may vary.

i do but its more of an habit i guess .... if you ever had an 600€ phone bill you know what i mean


Wifi can actually drain your Battery because it constantly updates the available WLANs

At home I turn on wifi and turn off data. Vice versa when I am not at home. Simple :)

Awareness is key. Never enough, even in the face of futility. Speak the truth as if you may never get to say it again. This world is full of ugly. Change it they say. The only way is to reveal the ugly. To change the truth you must first acknowledge it. Never pretend it isn't there. Never bend the knee.

No, not unless I am leaving the house for example, for wifi... and for mobile data, only turn it off if I am in a poor coverage area for a while as it will constantly be looking to try and connect.

I used to turn them off when not needed, but that had very little effect on the battery TBH for me, but again your mileage may vary.

Please quote my post, or put @paddy-stone if you want me to respond to you.

Strictly speaking, you don't need to unless you're on the fringe of a given network and making your phone strain to stay connected.


The battery life hit from leaving WiFi and mobile data on is normally quite low these days.  Your phone doesn't check for available WiFi networks often enough to really hurt the battery.  And besides, having WiFi on can help with positioning, plus public hotspots you might want to use (I'm thinking in underground train stations and other places where you'd otherwise have trouble connecting).

I used to have the Stamina  Mode on (Xperia's software) which would disable the WiFi when the screen was off and periodically check new notifications... but it was around 5 years ago and things were different with less notifications, since then I've never tried to enable that feature in any other phone, but sometimes I just turn on Airplane Mode when I don't really want to use the phone and/or want to save some battery (i.e. doing a bit of tourism, I quickly check the directions for some place, turn on Airplane Mode, walk for 15 mins and if in need, check again)

But besides that, I always have wifi or data enabled and the only time I don't have it on is when I go to sleep. If it's important call me, don't text me via WhatsApp.
