Good to know. I have my original battery (bought my n800 the day before they were released) and I generally play high quality videos or streaming audio at work. It will only play audio for a couple of hours, and if I try to download a file via the network from one of my shares, I will almost kill the battery for 500 MB download. So, perhaps time for a new battery. Granted this is all quite anecdotal, but I have noticed that "it sure isn't what it used to be".
