官方注释:Standby: Testing conducted by Apple in May and June 2007 using preproduction iPhones and software. All settings were default except: Call Forwarding was turned on; the WiFi feature Ask to Join Networks was turned off. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary. 作者: woowoo 时间: 2007-6-19 23:07
Another concern for early iPhone testers, Wu said, is battery life. Apple says iPhone will deliver up to eight hours of talk time (6 hours of Internet use, 7 hours of video playback or 24 hours of audio playback.) The company also claims the iPhone will feature up to 250 hours-more than 10 days-of standby time.
"We hope those times are accurate, but some of our sources have indicated iPhone's active use battery life may be closer to around 4-5 hours for heavy use, similar to other smart phones," the analyst told clients. "However, because an iPhone also serves as an iPod, unless Apple's claims on performance specs are accurate, 4-5 hours of video playback may not be enough for usage such as on international flights, and for phone use afterwards."
Wu said he'd like to see Apple move to a replaceable battery design at some point, similar to its MacBook and MacBook Pro product lines. "We believe this gives customers more flexibility and could even create a lucrative, aftermarket battery marketplace for Apple with its licensing partners," he wrote.
