Dave,

I have an ipod touch I upgraded to 2.0 and I have downloaded several of the new apps.  Most can only work when I am on 
wireless and I notice that the device gets hot as you said and that the battery indicator seems to drop as I watch it.  
I do not use it for email, so it that is not it.  Wireless was always battery intensive on the touch, but not like this.

As much as I like the ipod touch and the iphone, I would not think of giving up my BB (t-mobile) until both Apple and 
ATT get their act together.  I have called t-mobile at all hours of the night from all over the world when I have a 
problem, and they are typically there and helpful.

Steve

It is my experience that battery life is much worse in practice. I have a 1st gen iPhone with 2.0 software. 
Periodically the phone gets hot as hell. Why, no ideabut the battery goes down fast. Might be the "push" mail but 
sometimes it is good sometimes bad . mail always runs?


By the way I am still deeply disturbed by the lack of understanding of Apple that many of their customers do not enjoy 
standing in line in the heat just because Apple can not seem to understand scheduling . Weird. Dave Crocker might have 
it right.

Dave

Dave,

Given the iPhone's expensive to replace (for non-hackers) "permanent"
battery, I'm interested in reports of rapid battery decline
associated with the rash of new iPhone applications, many of which
involve keeping the display lit, long-period data streaming, etc.

Question: Will the new applications make the non-user-replaceable
battery much less palatable than previously, given that many users
may burn through its available cycle life much more rapidly than
before?

Thanks.
