A number of times lately, I've got up in the morning to find my iPhone is dead. Looking at the battery usage, I see that the BT Wifi app is active in the background during the night - strangely, starting at 3a.m. I think it's looking for a BT Wifi hotspot but don't know for sure. My home wifi is available all night so I don't understand what it's trying to do. If it carries on, I'm sorely tempted to delete the app altogether. Can anyone advise?
go to app then connection settings and turn off stay connected
Bt Broadband customers are automatically signed in to BTWIFI and requires a manual effort to sign out of BTWIFI
you don't share your home wifi but your hub sends out a BTWIFI network which other people can use but it is totally separate from your home network which remains secure
if you have opted out then no point in having the BTWIFI app
