Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 113600 Hz | ≤ 75 % brightness setting |  |
The display backlight flickers at 113600 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 75 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 113600 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

相信很多买家已经等了这款全新MacBook Air许多年。重新设计最大的亮点就是屏幕，相比老款MacBook Air，新款的屏幕在分辨率上得到了很大的提升，然而在亮度、色域和质量上仍然比不过更贵的MacBook Pro，苹果的原厂校色值得称赞，所有的测量值基本上都在标准范围内。新MacBook Air采用了亮面屏，这并不新奇，但与上一代相比，新款更加引人注目。
新设计的外壳给我们留下了很好的印象，但是与MacBook Pro 13相比，Air并没有便携性上的明显优势。它们的占用面积相同，而Air的后部甚至更后；重量差异也只有100克，很难成为购买的理由。如果你想要最小巧的苹果笔记本，MacBook 12仍然是最佳选择。
我们最初的Wi-Fi续航测试得出了11-12小时的优秀结果，但是再次充电花费的时间较长。
处理器在一开始的跑分中没有给我们留下好的印象，因为与MacBook 12和老款Air相比，性能几乎没有提升。不过即使在长时间使用下，新Air仍然能保持同样的性能水平，只是风扇会比较响。我们不禁发问，对于日常使用来说，性能是否足够？是的，目前来说的确如此，但是，Air的竞品们均采用了性能更强的处理器，甚至有着战未来的能力。
这就回到了我们当初的问题，那就是，新款Air在苹果众多MacBook产品阵容中是否显得多余？稍加思考我们就能理解为什么今年苹果没有更新MacBook Pro 13（改进的键盘，Touch-ID，TrueTone和更快的处理器）。因为如果更新了，买家就没有什么理由去购买新的Air。但即使没有更新Pro 13，较低的价格基本上还是新Air的唯一优势。
下一次更新将包括噪音测试，我们还会看看苹果是否真的改善了扬声器性能。
