3G SmartPhone Battery Life: iPhone Leads





The battery life on Apple's new 3G iPhone isn't great, but it beats that of other 3G smartphones we've seen, say testers at PC World's Test Center. In the study's standard talk-time battery life test, an iPhone, on average, ran 5 hours and 38 minutes, a performance PC World deems "fair."

The original iPhone, which ran on AT&T's slower EDGE network, lasted 10 hours of our test. But the 3G iPhone beat out the rest of the current 3G smartphone pack, most of which fell shy of the five-hour mark that's the cutoff between a word score of fair and poor in PC World's performance ratings.

The iPhone 3G also beat out competitors on Sprint and Verizon's EVDO mobile broadband networks, including the Palm Centro (4:19) and the Samsung Instinct (5:33), PC World says.

More IPhone 3G internals photos



Portelligent and Semiconductor Insights published a document describing interals of IPhone 3G. Techonline described the details. (Previous IPhone 3G internals photos can be viewed here)

Commuunications (3G/GSM) are on Infineon chips. One for GSM/GPRS/EDGE, another for WCDMA/HSDPA (3G). GPS module is not SiRF as we all thought. Apple uses PMB 2525 Hammerhead II. The Hammerhead II integrates an assisted-GPS (A-GPS) baseband processor with a low-noise GPS RF front end and multi-path mitigation to avoid large errors in urban environments.
