Here is a good place to get some thoughts: http://androidforums.com/motorola-droid-razr-razr-maxx/598942-s3-droid-razr-maxx.html

 

I actually just got a S3 a few days ago and so far I'm LOVING it! Battery life hasn't been bad at all. I got 15 hours with medium to high usage the first day and yesterday I was at 65% after 10 hours of medium usage. If you already have it in your possession give it a try for a few days and see if you like it!

 

Maybe it was because I came from a Droid X, but when I got the S-3 to beat the unlimited access deadline, I wasn't satisfied. The S-3 sounded great with all the hype, but it just felt awkward in my hand and I wasn't impressed by the gimmicky features like touching phones together. Small things but I took it back for the Maxx and am very comfortable with it and the extended battery life. I felt like I was going backward in some ways but of course it's all subjective, they're both great phones. Take some time to explore the S-3 and make a decision then.

 

Sell the s3 on ebay since it's still new you can get top dollar for it probably

 

I had a $299 Samsung Nexus when it came out. Couldn't get it to work right so Verizon let me swap it for a $299 Razr Maxx. I see that now the Nexus is $99 while the Razr Maxx is still $299. That says a lot about the Razr.

 

Great thinking!
