Par for the course, really?
The RAM has very little to do w/ power consumption of a smart phone (it's next to last on the power consumption charts last time I checked), and especially the amount of it. RAM pulls the same power constant regardless of size/how much memory is actually being used iirc. If you're going to attack Android phones over shorter battery life then you should be attacking the CPU/Display/4G networks.
Try thinking critically for once. This was an obvious spin article. There is no reason they couldn't have upped it to 1 gig of RAM, other than that they knew their zombie consumers probably wouldn't care since they're all too invested in the "ecosystem" in the first place.
