In the morning when I take the bike to work, I have my Xperia Z2 in the backpack.
If I am then at work, I take it back out and put it on the desk. Since the last update my Xperia Z2 has ever the data connection and also builds these no longer autonomously on. Even switching between airplane mode does not help. I always have to restart the Xperia Z2. It seems, according to his display but only the data connection and not the entire network connection.
This was previously not so and other colleagues, which almost identical way to work as I have, the problem did not. However, they also have other smartphones.
