Performance: Battery life
We test battery life in two scenarios, one "worst case" and one "best case" scenario. The "worst case" battery test consists of SunSpider in the foreground and a playlist with music in the background. For the "best case" battery test we play and loop an MP4 film until the battery dies. WiFi is enabled during the test, but it's not connected to a router or access point.
It's clear that the battery in the ASUS Transformer Pad Infinity TF700T drains quickly under heavy loads, but that's not really a surprise. The other ASUS tablets traditionally don't score that well in this category. The score for the Prime here is without dock, even though it says otherwise. When playing back a video file the companion core of the Tegra 3 does a great job of improving efficiency, with an impressive 10-hour single charge. Watching movies on transcontinental flights is definitely possible.
