I got it about a year ago. I watch NetFlix on my PS3 semi often and occasionally watch a BD movie. Using a PS3 controller to watch movies/TV shows is just annoying.
Anyway, the batteries that came with the remote died a few months back. I actually thought the remote was broken or needed to be resynced. I didn't think the batteries could possibly be dead after such short of time. Well, maybe the batteries that came with it were new old stock or just cheap or whatever. Benefit of the doubt. But the batteries that I put in a couple of months ago have died already! Why does this thing kill batteries so quickly?
My thoughts are this: The remote has to communicate with the PS3 via Bluetooth, right? So if I turn on my PS3 with my remote, the remote is connected to the PS3 and stays connected (using battery power) the entire time the console is powered on. Unlike an RF remote that only uses battery power when you press a button.
Pretty annoying. The batteries in all my other remotes last for years, but I guess I'll have to change the batteries in the PS3 remote every ~6 months.
