Did the CPU speed go up in 1.1.2?

[ebp2kEM1]

I looked before and after.

1.1.1: 400

1.1.2: 412

They bumped the bus speed by 3 MHZ, which means a 12 MHz bump in the CPU speed.

I also found a site that debunked the 600 MHz claim. Don't have it handy, but there are several out there.

For the record I can indeed stress the CPU (via multiple SSH sessions, all running tasks), but it never goes above 412 MHz (just as it never went past 400 MHz under 1.1.1). It also never drops below 412 MHz.

So, again, I am 90+% convinced Apple increased the clock speed in 1.1.2. It also doesn't seem like they are using CPU scaling in the iPhone at this time.


BTW: There is a lot of doubt the CPU is spec'd to 600 MHz. What I am saying is, even if 600 MHz is true (which I doubt) Apple capped to a lower speed to save battery life. This could be how they magically increased battery life a month before the device hit the streets. And, for some reason, they have increased it (a little) in 1.1.2.

Mike,
To add more fact to your claim. I have noticed here and in other forums. iPhone users are reporting faster battery drains, after updating to 1.1.2. Once again you have found the elusive answer to the question...M

I wonder...is that a good trade-off? Faster clock for shorter battery life. Is it worth even upgrading to 112? What do we get with that update besides multi-language w/keyboard?

I haven't noticed any significant decrease in battery life. Ive been on 1.1.2 for three days now.

It also isn't a whole lot faster - so it shouldn't be a huge drain on the battery.

Same here. Good so far but not as good as I had hoped for.

My battery life also seems no different.

Is it reasonable to expect to notice a difference of a 3% faster clock in either application speed or battery drain? Interesting that they did it, but why bother?

I am on 1.1.1

400.00MHz
100.00MHz

Every little bit helps and so far 1.1.2 is indeed snappy for me.

It is becoming obvious that a change in CPU speed did indeed occur with 1.1.2.

Haven't noticed any less battery life, but that has always varied (depending upon usage).

More importantly, to me, is that this bodes well for a possible future over/under clocking utility. Lower speed to save battery (say 200 MHz), higher for CPU-intensive apps (games, etc.).

Agreed... My 1.1.1 phone was always quick compared to newer versions of the iPhone, i have one of the originals, now with 1.1.2 its blazing quick!

Anyone else notice how much faster wifi runs as well?
