Cell Phone Plan Comparisons

Comparing Cell phones & Sirius Stiletto Radios, how does the electrical needs of each device compare?

I would like it if someone could explain or breakdown the ingredients of both battery types and detail how the electrical needs of each device compares. If there's any other ditsy people like Summer who are oblivious to what I'm talking about, the Sirius Stiletto is a Portable Radio put out by Sirius.

1. I did not know that they made high-heel radios. I've heard of sattelite radio though.
2. Both use Lithium Ion batteries because they are relatively high drain devices. Cell phones can last a week on a battery.... if you're not making or receiving any calls; just standby. When you use it, the phone's transmitter takes a lot of energy and you'll run it down in a few hours. Now that cell phones are getting smaller and smaller, this reduces the amount of space available for a decent capacity battery. The Stiletto is similar in the sense that depending on what you do with it determines how long the battery will last. The least power hungry feature is the MP3 or recorded audio player. Next in line would be the Internet Radio player which operates through WiFi. Finally, the most power hungry would be the Sirius satellite radio receiver. The reason why has to do with the chipset and the complexity of the signal. The Sirius signal is approximately a 4mbps stream of data which contains all of those channels at the same time. This takes a significant amount of horsepower (in the form of a microprocessor) to decode it all and pick out the audio you want to listen to. The chipset isn't 100% efficient, either. Energy is wasted in the form of heat. Future revisions of the chipset as technology advances will yield a portable receiver with better battery life. The Stiletto comes with both a standard battery which fits flush on the back and an extended life battery which protrudes from the back a little bit. The Stiletto's batteries are generally of a higher capacity than cell phone batteries (thus are larger) because it takes more power to use.
