I would interpret twice as fast, and that's only 50% rather than 100% reduction of execution time :)

relative performance = new time - old time / old time.
2x = -50%
3x = -75%
etc

-100% means new time = 0, and performance is infinite.

"The benefits? Some sources are reporting a 50% increase in speed. Others say it’s closer to 100%. Many claim they’ve seen their battery life increase by 25% or more!"

Got to love those 100% speed increases.  Apps really fly when they take no time at all...
