Comment 6 for bug 1373463

I am using Ubuntu on my primary phone so I can confirm that disabling
cellular data save battery, and a lot (less than on Android it's sure).

Then, I'm all the day on the road, in places with by coverage generally
(mountains), so disabling cellular data is really an important battery
saver for me (and every one, even if they are on Android, in my team). I
often forget to disable Wi-Fi and it doesn't use as much battery.

I don't know how Ubuntu manage this, but probably, if Ubuntu switch to 2G
only when there is no data (it's not really clear with current design), it
would explain why it's save so much battery for me (more of that, no 4G, so
everything with in 3G, the worst for battery)

I understand that every little think added add more clutter to the
indicator, and so it lose interest. Do you know if there is a tool to
measure battery usage ?
