Well that's the magic of a RAZR Maxx ;-) I know for a fact that if I turn on WiFi instead of 4G/3G on my phone then I get at least 2 more hours of extra battery life. I know that this isn't any iPhone 4S but it's still worth it. Well thank you MattyP for your great tutorial - - hope it helps others as much as it helped me ;-)
No problem at all. I think alot of people just take the phone out of the box and turn on all the bells and whistles and then they wonder why the heck is my battery dropping like a lead balloon? And besides, if you start an app that needs wifi or GPS, it will say "you need to turn on wifi or GPS". But if you leave it on, it only chews on the battery.
