For lack of signal, any phone would use more battery.

The relevant, and most interesting part is: NOTE: Please note that with any mobile phone; if you are in an area with no wireless coverage, your Treo searches for a signal, which consumes power. If you cannot move to an area of better coverage, temporarily turn off your phone. While your phone is off, you can continue to use the non-wireless features of your Treo. What they don't say, but what I think applies here most strongly is that in areas of marginal coverage, the Treo consumes more power by having to "work harder" to hang onto the signal. Turning it off isn't an option in the circumstances in which I most often find myself. When I'm up in the mountains out of coverage area I do turn it off. The battery life seems to be about 7x with the cellular radio turned off. Sorta reminds me of the Pilot days. Well, only sort of. Remember having replaceable batteries that lasted a month? Of course, with that came a monochrome backlit screen, but why quibble? Addendum: It seems that my experiment is proving my hypothesis. With the longer antenna back in place I have not noticed the rapid battery drain. I've only been in my stationary poor coverage area once since then. I'll be testing that again next Tuesday!

I just got the short antenna on the 700 about a week ago.

Since a digital phone only puts out a signal when it's contacting the tower or actually being used to make a call, warmness happens at that time. I infer that the warmth that I notice (and you did too) when the phone is not in use is caused by its having to up the power output to get/keep in touch with the tower. Do also notice quicker battery drain? I suppose it could be a coincidence and my Seidio 2400mAh battery could be just getting old, although it's only 9 months old.

I have noticed that my 700p also gets warm even though I am not using it and it is set not to access the broadband access. Why is it getting warm?

I think the consensus has been that there is little if any degradation in signal associated with using the short antenna. In my experience that's true, with one apparent caveat that's important to me, even though it might not be important to others. I live in the Denver metro area. In Denver proper, and in most of the larger suburbs, Verizon's signal is quite good. Not great everywhere, but one can make a call without much fear of having to say "What? What? I can't hear you! I'll call you back!!" However, the area is sufficiently large and the population sufficiently spread out that there are many times when the signal is just barely good enough. Here's where the difficulty comes in. I have now spent the majority of a day twice with the short antenna in an area of marginal coverage. It is an indoor location in which I've spent many days in the past, and I never had a problem with the original antenna. I noticed on each of these two recent occasions, however, that the battery plummeted in power, going from 85% to 20% battery in a matter of 6 hours on one of the trips. I didn't make any cell calls during this time, either. This is very unusual. I use a Seidio 2400mAh battery which always gets me though the day. During this time I noticed that the Treo seemed warm all the time, too. What happened during these two days tells me that the signal is just degraded enough that the Treo was constantly having to reach for a signal, burning through the battery in short order. During this second trip I actually turned off email sync and Bluetooth, leaving only the cell connection, just to make sure something funny wasn't happening with Exchange Activesync or with Bluetooth. The results were instructive! The battery drain happened with no email, no cell calls, no Bluetooth. I'm actually sending this email from that same marginal signal location right now, having put the originally antenna back on yesterday. I've been here two hours and have made one 5-minute phone call and the battery (with Bluetooth on and Versamail push enabled) has dropped 4%. That's more like it!! I will probably experiment further, but this seems pretty conclusive. For me, the short antenna doesn't work because of the areas in which I find myself. If I were just in Denver all the time, it'd probably be just fine! I'll report back if I find more data points, but in summary I didn't notice any call degradation, but in formerly-marginal areas the battery lost about 10% per hour.
