7 Worst Battery Life-Guzzling Gadgets
ASUS Taichi ($1,299)
Battery Life: 4:37
Cost Per Hour of Juice: $282 per hour
One of the most innovative Windows 8 hybrids of the year is also one of the most disappointing. Almost everyone who sees the ASUS Taichi, which has a second screen on the back of its lid, can’t help but say, “Wow.” All you have to do to transform this 11.6-inch wonder from clamshell to tablet mode is shut the lid.
While we wish both displays offered touch capability (just the outside one does), my biggest complaint is the lack of staying power. In laptop mode, the device lasted 4 hours and 37 minutes, and with just the touchscreen active, we saw only 3:37. The average ultraportable laptop lasts 1.5 hours longer. While it’s bigger, the $1,199, twelve-inch Dell XPS Duo lasted 5:46, translating to a much better efficiency rating of $206 per hour.
