iPhone 3.0 and ACID3 Test

Very disappointing, I upgrade my iPhone 2G to 3.0 last night and ran the ACID3 test again (see http://acid3.acidtests.org/ ), as iPhone 3.0 was released after Safari 4.0 was released for Tiger, Leopard, Snow Leopard, and Windows, and Safari 4.0 gets 100/100 I was expecting the iPhone to also get 100/100.

However it 'only' scored 97/100 😉

By the way, Safari 4 finally has teh snap 🙂

MacBook, Mac OS X (10.5.6)

I would guess that your iPhone isn't quite fast enough to complete the tests fast enough.

Taken from http://ln.hixie.ch/?start=1207096078&count=1
"To determine the "score" for performance in a browser that gets 100/100, click on the "A" of "Acid3" on the test after having run the test twice (so that the test uses the browser's cache). An alert should pop up, giving a total time elapsed, and reporting any tests that took longer than 33ms."

Each of the 100 tests has to be completed in 33ms or faster in order to pass. Try checking to see if that's the case. Your 2G iPhone probably doesn't have the speed to do that, while the newer 3G or 3GS might.

However, we're talking ms here, and a 97 is pretty darn good!

Yes I am using an iPhone 2G (via WiFi), and thanks to your tip clicking on the A reveals several tests took longer than 33ms. However it did say three tests failed as follows -

Test 46 failed - expected 'none' but got 'uppercase' - case y2 failed (index 22)
Test 77 failed - expected '4776' but got '5552' - getComputedTextLength failed.
Test 78 failed - expected '90' but got '0' - getRotationOfChar(0) failed.

So these appear to be real failures not due to the slowness of my old 2G iPhone. 😟

iPhone OS 3.1 now passes 100/100 on the ACID3 tests, and is fast at doing it as well.

Congratulations to Apple.
