更智能的Siri

????蘋果的個人數(shù)字助手Siri給大家?guī)硗耆煌捏w驗。全新打造的用戶界面不必多說，可以同時使用男女兩種語音也符合人們的期待。更重要的是，蘋果還承諾將提升Siri的應(yīng)答速度、答案來源也將更多元化。新的Siri更可以完成回電話、播放語音郵件，或者控制iTunes Radio等復(fù)雜功能。

續(xù)航時間更長

????和OSX小牛一樣，iOS 7也進行了徹底改造，以實現(xiàn)終極節(jié)電。例如，應(yīng)用程序能利用新的多任務(wù)系統(tǒng)判斷用戶的無線或WiFi信號是否良好。如果信號夠好，應(yīng)用程序就能獲取數(shù)據(jù)——這將消耗電能，如果信號不夠好，它們就繼續(xù)等待。（在信號不好的情況下獲取數(shù)據(jù)會消耗更多電。——譯注）

A way better Siri

????You'll notice something different about Apple's spunky digital assistant, and we're not just talking about a new coat of paint, or the fact that Siri sounds more natural with an updated male or female voice. Apple promises faster answers to questions, more sources for Siri to dig through, and the ability to ask it to return calls, play voicemail, and control iTunes Radio.

Better battery life

????Just like OSX Mavericks, iOS7 was designed from the ground up to conserve battery life where possible. As just one example, the new multitasking ability helps apps figure out whether or not users have a good mobile or WiFi Internet connection. Depending on signal strength, apps will fetch data -- drawing energy from the battery in the process -- or hold off.
