I usually forget to switch it back on and end up using my 4G allowance at
home...

My Android phone uses wifi in preference to mobile data, when wifi is
available.

Assuming wifi is switched on, of course.

It can be SMS, it could even be electronic billboards or display

you, you'll be pleased to know that we currently have 50p off our jumbo

Why would anyone use a phone at home when there are alternatives with proper
screens and keyboards, virtual or otherwise, not designed for fingers the size
of those of a 5 year old?

Are you presuming that there is a correlation between whether people
keep wifi on and choose particular routes? If we assume they are
independent then TfLs analysis still stands.

Presumably by analysing ticket data we can see what percentage of
passengers are carrying a device with wi-fi enabled (although in my case
that is often 3 or more - before you ask, personal phone, work phone and
kindle)

You have to carry a work phone? You have my sympathies. There's nothing worse
than the invisible leesh tying you to the office when its not really required
by the job (ie you're not a travelling salesman or on site engineer etc).

Why change environment when you're used to reading fb, usenet, text,
WhatsApp etc on your phone all day? Not tied to one room, use it in
kitchen, lounge, bedroom, bathroom, garden etc. In any case my laptop and
desktop are both so slow that they really need replacing - but I use them
so little that it's not really worth replacing them...

Thats a bit like saying why bother switching to a 32 inch TV in the evening
if you've been watching stuff on a 4 inch one all day.

I fell foul of this, switched off wi-fi and the phone used all my data
allowance when the software / apps updated - should have been free over
wi-fi but ....

Lesson learned!

Sheesh! My dog would tell you he's mostly on a leash.

Can't browse fb/usenet on my desktop while I'm watching that 32" TV, though

Well indeed, and the reason I carry a work phone is that I don't have an
office and can therefore work wherever I feel like but obviously need to
be in contact.
