Battery Life - Keeps getting better

Engadget editor Chris Ziegler recently reviewed Motorola's new Defy.  In case you forgot, this is Motorola's new 'party phone', water resistant, scratch-proof screen, something about rolling around in the sand (watch the commercial...).  This is also the Oprah phone... the phone given to the audience members of Oprah's first show of her last season.

But I don't want to talk about all that.  The Defy comes with Wi-Fi Calling.  Some industry commentators continue to propagate the rumor that excessive Wi-Fi use drains a smartphone's battery.  That may be the case, unless that phone has Smart Wi-Fi technology.

In Chris' review, he actually credits Wi-Fi, and Wi-Fi Calling (aka Smart Wi-Fi), as the reason why the battery performance was "stellar."

"In our experience, the Defy seems to have stellar battery life, which is relatively hard to come by among Android phones. Not only we were able to consistently make it comfortably through an entire day on a charge, but we were surprised to find that after putting the phone away with about 75 percent charge, it was still on with 21 percent remaining two days later. Granted, it spent most of that time in WiFi calling range (which disables the cellular radio), but many smartphones give up the ghost from 100 percent charge in less time, so we were pleased to see that." 

Smart Wi-Fi... actually making Wi-Fi on Smartphones 'smarter'.
