More iPhone battery test results

Music playback time is in and the results are good.

Apple's iPhone

We have more iPhone battery results from CNET Labs. The talk time, video time, and music time tests are completed and we can report that the iPhone largely delivers on its power promises. And just to remind you of those promises, the iPhone has a rated battery life of 8 hours talk time, 24 hours of music playback, 7 hours of video playback, and 6 hours of Internet use.

Talk time: When we tested the iPhone with the Wi-Fi function turned off, we got about 7 hours, 45 minutes of talk time. When we tested it with the Wi-Fi activated, we came away with 4 hours less.

Video time: We were able to play 7.3 hours of video with the Wi-Fi function turned off.

Music time: Music-only time was also satisfactory. We got 28.4 hours of music playback time on a single charge.

Just keep in mind that it's rare you'll be using just one feature for hours on end. As such, your battery life will vary widely as you switch between functions. Large color screens such as the one on the iPhone tend to be battery drainers, so you'll most likely need to charge your handset every couple of days.

Details about Apple's 'spaceship' campus from the drone pilot who flies over it

MyithZ has one of the most popular aerial photography channels on YouTube. With the exception of revealing his identity, he is an open book as he shares with CNET's Brian Tong the drone hardware he uses to capture flyover shots of the construction of Apple's new campus, which looks remarkably like an alien craft.
