We’re still working on iPhone talk time testing and we’ll be doing another round of audio and video tests with 3G disabled – but at least we have another piece of the puzzle to add to our review.
To give some context the test results, we also retested the first-generation iPhone, and simultaneously tested a comparable 3G multimedia phone, the Samsung Instinct. Apple’s public tech specs claim the iPhone 3G is capable of up to 7 hours of video playback and 24 hours of music playback. Surprisingly, with 3G switched on the iPhone sailed past 24 hours of music playback, but Tank when it came to video. Further testing with 3G disabled may yet redeem Apple’s claim of 7 hours of video playback.
Enough talk – here’s the numbers:
Music playback Battery Drain
Apple iPhone 3G (Wi-Fi off, on 3G): 25.5 hours
Apple iPhone (Wi-Fi off, on EDGE): 31.4 hours
Samsung Instinct (on 3G, Wi-Fi unavailable): 18.2 hours
Video playback battery drain (same settings as audio)
Apple iPhone 3G: 2.68 hours
Apple iPhone: 5.99 hours
Samsung Instinct: 4.28 hours
For good measure, we also threw in a data transfer test, which measures the time it takes to transfer a single 500MB file to the phone from a PC. Files were transferred in iTunes 7.7 for both the iPhone and first-generation 3G iPhone, and Windows Media Player 11 for the Samsung Instinct.
File transfer speed
Apple iPhone 3G: 1.35 minutes
Apple iPhone: 1.6 minutes
Samsung Instinct: 7.71 minutes
