Jack Bauer & Battery Life

We are currently trying to upgrade our cell phones. We've been pouring over the specs to see which ones are the best. One of the specs that is important to us is talk time or to put it another way, battery life. Most of the phones we've looked at are rated at somewhere between 3 hours and 4 hours of talk time. Standby time (no talking just waiting) is somewhere in the neighborhood of 300 plus hours (some as high as 16 days or 384 hours). So if no one calls you, your battery can last up to 16 days without recharging (yea right). But if someone (or several someones) does call you have at most 4 hours or so before you need to recharge.

So how does Jack Bauer talk on his cell phone during the 24 hour crisis he faces each season? I have yet to see him charging his phone in his car or at CTU. Maybe he carries around extra batteries (at least 6, 6 batteries X 4 hours of talk time = 24 hours). He carries around ammo clips so why not batteries? I have yet to see him change a battery. Maybe he does it while he's off the camera and we are seeing another scene.

Then again I have never timed how much time he spends on his cell phone. Maybe if we timed it he doesn't use his cell phone for more than 4 hours. You know that would be an interesting feat for someone, timing how much Jack Bauer uses his cell phone on 24. I can just see it now on Trivial Pursuit under the "Entertainment" category - How much time does Jack Bauer actually spend on his cell phone during the season of 24?
