I did have a few doubts. If you watch the video, the battery is accessed via an app out side of settings. Maybe this is possible but its also not difficult to write an app that will mimic this. What I want to see is a DEAD phone that will not turn on charged to full.
I have no doubt that the battery level displayed is genuine. What I do doubt is how much juice is actually in the battery they have connected to the phone; supercapacitors aren't new. They also have severe issues with actually providing enough sustained power to be useful in a cell phone context.
Remember that story about a year ago about the high school girl who was going to charge your cell phone in 20 seconds? Same promise, same problem - supercapacitors charge really fast, discharge really fast, and just can't compete with a l-ion battery.
As soon as someone demos one of these batteries that can actually provide 10 watt-hours on a 30-second charge, call me. Until then, yawn.
