Help 3G vs. Wifi


Well-Known Member
so i've heard on here that Wifi uses less battery than 3G.

Why is it that when I have Wifi on it comes up under battery use but when 3G is on it doesn't show anywhere. Is it just lumped in with something else like android system or something?



Android Expert
3g is included as "Android System"

Turn on airplane mode for a few hours (like I do at work) and you'll see that android system uses a significantly less amount of battery.


Frell me dead
The simple explanation why Wifi uses less battery is that the range of WiFi is quite significantly lower than the 3G, therefore the radio in our beloved devices do not have to push as much power to acheive and maintain connection. This would be great for me because I am almost constantly with good WiFi connection, however my S.O. and I work vastly different shifts and when she is at work, just about the only way to contact her is through Skype, which does not work with WiFi for me :(
