I have the extended battery on my Droid 2. My phone can go uncharged with moderate usage for about 3 days. When I got it from Verizon, the extended life battery was the same price as the regular battery. I got it replaced under warranty, because I went through so many of the Samsung Omnia 2's. That phone was pretty cool, but it had so many problems. They kept on sending me a new Omnia 2, but they all had the same problems which were never fixed, so I paid $50 and got a brand new, just released Droid 2. I love the battery life on my Droid 2. Longest life than any phone I have ever had and it has a 1Ghz processor. I'd say my most favorite feature about the phone is that I can sync my Facebook up with my phone and it imports all of my friends from FB and all of their information including their FB picture, email addresses, home addresses if they have it listed, cell phone number, etc... Most of my phone numbers on my phone are from FB. Oh yeah, if you import your contacts and have your FB contacts, you can link them both together. Pretty awesome feature. Oh yeah, takes just a couple of clicks and you can upload a picture straight to your FB with the "Quick Upload" button. Easiest phone I have ever had to use too.
