Apple's tooting its own horn about some new spec upgrades to its imminent iPhone. No, it's not 3G, GPS or anything crazy like that, but we'll settle for a battery life upgrade anytime, and screen durability doesn't hurt neither. Apple claims that its preliminary estimates of 5 hours of talk time, internet use and video playback were a tad conservative, and the iPhone instead will be boasting of 8 hours of chatting, 6 hours of internet and 7 hours of video. Audio playback has been boosted from 16 to 24 hours, and standby is at a welcome 250 hours. Of course, Apple does have tendency to exaggerate slightly on the battery life front, but these are promising figures, and should manage to provide a day or two's worth of solid use out of the thing. On the screen side, Apple has upgraded the original plastic surface of the phone to some "optical-quality glass" to improve scratch resistance and clarity. Check after the break for a handy battery life chart.

Update: Not sure how we missed this little snafu, but no Apple, you aren't the only one on that chart with WiFi.
