I updated my new Droid RAZR to 6.12.181 last week. Before, I had multiple issues, including horrible battery life. After the update, I've talked on the phone for almost three hours with barely a noticeable drop in the battery gauge. I've played games or used other multimedia features such as Youtube with the same results. It looks like (at least for me) this update really did the trick. It's like having a whole new phone.
After owning every iPhone since day one, I have to say that my current Droid RAZR has the best battery life I've come across. Way to go. I hope the ICS update builds upon this and makes for an even better user experience.
