Just traded my LG Revolution in today for the Droid Charge. The Revolution is a nicely built phone, very solid. Also it has a lot of great qualities including call quality (not the speaker phone).
That being said the screen is a bit washed out, battery life is okay, and it has a bit of lag at times. I threw Launcher Pro on the Charge to give the launcher and app drawer a stock feel and it is GREAT!!!!!
Good battery 1600 mAh, BEAUTIFUL SCREEN!!! Great call quality and much more!!!
Just as a general rule I run on 3G unless I need to download something of a larger size. This makes the battery last much longer than it would on 4G.
