I actually don't find any statistics but lot of websites advising to disable mobile data with GPS or Wi-Fi to avoid finishing out of battery. Here are few of them :

But you will find that it's very often advised to prefer Wi-Fi over cellular data to save battery : this prove that cellular data uses even more power than Wi-Fi (it depends, of course, how much you receive these two networks : a very good cellular is better than bad Wi-Fi, but when you are moving (train, car...), you often pass by bad cellular network. More of that, another reason that make cellular data using more power is that, when you have it enabled, there are a lot of background process that use the cellular network to share data (searching updates, mail, twitter notifications...), and of course, to send data, the phone use battery it wouldn't used if it didn't send these. I "test" a lot of time in the train to go back home (ie when I forgot to switch off data) : with cellular data, I don't have battery at the end, without data, I still have some. -- You received this bug notification because you are a member of Unity API bugs, which is subscribed to Network Menu. https://bugs.launchpad.net/bugs/1373463 Title: [indicators] Impossible to disable cellular data from indicator Status in Network Menu: Triaged Status in Ubuntu UX bugs: New Bug description: I was wondering : Why it isn't possible to disable data from the network indicator ? Probably with a switch button that offer the choice between no data or data activated (with the last data activated state (2g only or 2G,3G,4G). Why this ? Because it's the first setting to change to save battery, and probably one of the most used (I asked around me, everyone agreed they would prefer that over Wi-Fi if only one was possible). I think it's stupid to go to the settings app for the most common action (and very frustrating). Of course, this also apply for the battery setting page (that already contain Wi-Fi, GPS, Bluetooth and brightness settings). I asked that on the phone ML, I've been invited to file a wishlist bug there to "help" designers with next iteration of network indicator. So here it is !
