    Simple question, which uses more battery power, 3G or wifi?

    I'm gonna have to disagree. I believe 3g kills the battery pretty quickly compared to wifi.

    I can say with a fair degree of confidence (haven't done any methodical testing) that 3G eats up more battery than WiFi. On both the iPhone and the Droid, I find that leaving WiFi on gives me better battery life than if I had turned off WiFi and relied on 3G.

    My (loosely) timed testing reveals that: WiFi is far more efficient than 3G.

    Happy DROIDing​

    Do you GPS as in using Google Maps, or when GPS is accessed every so often, by checking your location through apps such as weather bug.

    Also, does wifi use less battery while constantly streaming? I killed my phone's battery (almost full) streaming a radio station, in 4 hours.

    Thanks.

    Do you SERIOUSLY think a bunch of Droid owners off the street are gonna' have a clue about a question even a Motorola Droid design engineer would have to do calculations to answer?

    Opinions - sure. But opinions are like $%&!_#, everyone's got one.

    Actually I find mathmatical calculations to be BS, I would rather have realworld opinions from realworld users who would be using the phone the same way I would.

    Mathmatical calculations are like **sh)(&%, every scientist thinks his is right

    The problem is, very few real-world users actually write down any real data on usage... They mostly give their opinions, which may be incorrect.

    But, based on what I've read in various places, it would seem to me that WiFi is a bit more efficient, most of the time.

    But I don't use WiFi because a couple of my widgets don't work with it. And the difference between 3G and WiFi is pretty slim, at any rate -- otherwise, there'd be no argument about which is more efficient. It'd be very clear that one is better than the other.

    WiFi uses more power then 3g. That's my opinion. I keep it on 3G except when I'm home then I put it on WiFi.

    I think my results speak for itself on the android forums.

    It depends on the quality of the signal. The weaker the signal, from my experience, the more current will be drawn from the battery to try to boost the strength of the receiver/transmitter.

    Do tests of your own. A guy sitting in the 3rd floor basement of a building 6 ft from a WiFi router will say WiFi is better. :icon_ banana:

    I just started leaving my gps on and I have not noticed any decrease in my battery life. Now I don't have any apps set to check my location continuously but I still leave it on. I figure its a pain to have to turn it on every time I want navigation, or places around me. I think as long you don't have apps set to check location on a daily basis then leaving gps on doesn't effect battery life.
