I have noticed after two weeks of owning the atrix that the battery life is average at best but somewhat weird at the same time. From my past experiences with blackberry and IPhone, both of which last longer, that once the battery gets to 30% or less on those devices it goes quick. On this phone it will still last several hours from that point. Of course, I am of the opinion that I shouldn't have to fiddle with this thing to get great battery life. Doing so in my opinion is letting the manufacturer off the hook and allowing them to falsely advertise the devices capabilities over and over again. Keep in mind I am not asking much, unplug at 6am do my work through out the day. You know the drill corporate email, take some calls, read some news, check the weather, etc.... I don't even watch movies on it and can barley make it to 6pm. I have depeleted the batter completely, that's where I noticed the strangeness in the 30% area. It lasts longer if I am out at a business function until late, beter than average chance I will be taking calls on a landline because the phone died.
Really need a good app that would show exactly what is chewing up the battery, but I suspect it is just the phone itself.
