Since the official launch at MWC, ASUS has been mum on how many hours its upcoming PadFone can stay on the treadmill for, but earlier today, we spotted an official promotional video -- which has since been removed from ASUS's YouTube channel -- that mentioned 16 hours of battery for the phone itself, 63 for tablet mode and 102 for laptop mode. Something smells funny here so we pinged ASUS, and guess what? Those turned out to be just continuous talk time over 2G, so perhaps said video clip was pulled to be re-edited.

Conveniently, ASUS was also kind enough to share some very realistic battery life figures from the lab. With the corresponding screen set to 137 nits (about half the brightness), you get the following for phone mode, tablet mode and laptop mode, respectively: 2.6 hours, 10.7 hours and 17 hours of continuous WiFi browsing; and 2.1 hours, 8.9 hours and 14.1 hours of continuous 3G browsing. Just as promised before, the PadFone Station (the tablet) and the PadFone Station Dock (the keyboard) do seem to pump up the battery by about five-fold and nine-fold max, respectively.

Now sure, these may make the 1,520mAh battery inside the phone look feeble and silly, but do bear in mind that these aren't the "up to" numbers. As always, stay tuned for our own tests whenever the PadFone finally lands on our doorstep.
