For all the complaints about battery life, I'm surprised no one has posted any information regarding the extended battery option. I've seen one post regarding someone looking for a case to cover their extended battery Imagio but nothing regarding the actual battery or it's life. So, I took the plunge, spent 40 bucks on ebay and got one. This is how it should have been from the start. Charged all day (16 hours), woke up at 5:30am, few texts and calls on the way to work (1hr commute), a little web browsing here and there (hour at most), and a 45 minute call on the way home. Still at 67 percent. Made a few more calls, surfed a bit and then tethered wirelessly for an hour (actually now) and still have 27 percent. I'm not particularly thrilled with the design but the bulge is flat and the new backing allows it to be placed flat with no rocking. You still keep the stock kickstand and all the other openings but the back now is all nonskid material as opposed to the nonskid/slick material combo on the stock. The weight is negligible but the battery door is much easier to remove than the original. All in all, I'm happy with my purchase and think that it addresses and puts to rest my main concern with the Imagio.
