Notion Ink has released a list of ways you'll be able to drain your Adam tablet's battery in around six hours, as a counterpoint to earlier talk of over fifteen hours of "normal" use. 1080p HD video playback at full brightness and volume will do it, the company says, together with playing a 3D augmented reality game with camera input and 3G or WiFi for data. Solid YouTube or other Flash video playback over wireless will also sap power quickly, as will streaming 3D maps over 3G and using the hardware GPS receiver. Finally, recording HD video using the Adam's rotating camera and streaming it via WiFi is apparently a sure-fire way to drain the tablet in record time. To be fair, none of that is especially surprising, but it does raise a couple of interesting use-cases, particularly the HD streaming potential. We've seen apps like Qik do real-time video uploads, but the quality is generally well short of HD.
