timmmay: Does airplane mode stop data leaks?

Lizard1977: Haven't tried that, but I wouldn't expect it to be different, as all that is doing is turning off the wifi and mobile data radios.  While I haven't turned off the wifi radio at night, I have turned off the mobile data radio, so (in theory) it should be the same as turning on airplane mode.  I'll give it a try from tonight anyway.

As mentioned by rugrat, airplane mode does more than that. By law, the manufacturer has to switch off all mobile comms. So you have

• Airplane mode (enforced by regulations)

   

  • Mobile data: No
  • Voice calls: No
  • Text: No

vs

• Mobile data off (user choice)
• manufacturer can possibly choose to ignore the wishes of the user

   

  • Mobile data: No
  • Voice calls: Yes
  • Text: Yes
