Apple slowly bumping up the speed on iPhones?

No. Battery life depends on CPU speed but not on code efficiency.
So they can keep the old CPU speed and battery life and use better
code to speed things up, or they can slow down the CPU and increase
battery life use better code to retain the same functional speed.

True, but CPU speed can be controlled by software, and I assume the
iPhone's is. It can be set to stay low when the device is "idling" and
cranked up when doing processor-intensive stuff like playing video. Love
the iPhone, hate it, or anything inbetween, it has a phenomenal battery
life for such a loaded device (WiFi, BT, etc.)

Your tilt has great battery life as well. I tried one and after hours of
playing with it it only lost about 25%

It is a big one. And it's a user replacement. My friend loves his. He had
the Moto Q But loved the Tilt so much he paid the 175.00 ETF to Verizon just
to get one. Sold the Q for 150.00 so it was almost a wash for the ETF.

This has been my experience, and why I've often gotten 3 days between
charges - even with WIFI use (which I use a lot).

I wish I had a Tilt! I'm still using a T-Mo MDA (HTC Wizard)- I'm waiting
for T-Mo to release a version of the Tilt (HTC Kaiser) that will be
compatible with T-Mo's oddball 3G frequency.

Not bad. I'm hoping T-Mo releases a version soon- my MDA is getting a
little outdated, despite the er, um, "unofficial" WM6 ROM I've installed on
it. I have a 2400mAH extended battery for the MDA that makes an already
thick phone thicker, because the standard battery (even when new) barely
makes it through a day with my use. I generally only use the extended one
when traveling and can't guarantee I'll have access to an AC or car charger
at some point throughout the day for a quick "freshen up."
