Start thinking about learning to count.

All are wrong!!! It is faster because Apple said it is. Never mind how fast, just go out and spend spend spend.

So what’s the battery life like in comparison? For example, how many hours of play in a given game/app on the new device vs the old one? Always good to know if the increase in performance has sapped battery life.

Dickalan: it’s 50% FASTER. You are correct that 50% is .5, but saying “I improved my speed by 50%” does not mean you took twice as long to finish. It means you multiply your old speed by .5 and add that to your old speed. Essentially you’re doing 3 units of work in the amount of time it used to take you to do 2 units of work.

You guys need a refresh, what is 50 percent as a decimal .. .5 100 percent is 1 and 200 percent is 2, so if the touch is twice as fast then it is 200 percent faster

nay says the scientist. If you say “faster than” then you’re using the first object as the reference. thus 100% faster would be correct

TapTap is correct. Its speed not duration.

if 'A' moves at 100mph and 'B' moves at 150mph then B is 50% faster or a 50% increase. To confuse the subject more you could also say that 'B' moves at 150% of the speed of 'A'.

Actually, Tap Tap, doing the math, you’re right. For the increase in speed it should be 100%. I concede!

I disagree, “faster” refers to speed, not to duration, and half the wait means twice the speed.

David is right. You have to place the percentage on the newer or faster object. The car analogy stands but the percentage is on the faster car: 100mph vs. 200mph. 50% of 200mph is 100mph, thus a 50% increase. Right???
