Re: Does wifi really save battery life?
Yes WIFI saves battery, but it really comes down to signal strength.
BTW, Airave does not (currently) support 3G.
At my work I have both WIFI and Sprint repeaters (repeaters installed by Sprint in our buildings to boost signal strength (including EV-DO r.a)) So I get everything full strength (well since the WIFI antenna is directly outside my office and the Sprint antenna is a few floors down, WIFI is stronger.) I realize no difference in battery drain between WIFI and 3G. At home, my 3G signal is not as strong and I can see a difference (using WIFI improves my battery life at home by about 40%).
Now 4G is a different story all together. I do have 4G service, it is strong outside (outdoors) both my work and my home, but inside my home it is weak and inside my office it is zero. Turning on 4G drains the battery quickly.
