Some improvements since Gingerbread

First, my call quality has been much better. When walking down city streets, I was unable to hear anything. Now it's much better. The other massive improvement is battery life while using LTE. I had gone into permanent 3G usage to save battery life, and it worked well. After the outages this week, I switched back to LTE, and stand by battery life is much improved. I wonder why this has happened, and if it's permanent.:confused:

I'm still happy with the battery life. And now the GPS has been more accurate lately - and it had been pretty dismal in the past. Maybe it's the weather; it seems that the colder it gets, the better this phone behaves.
