The battery was improved in the 2016 refresh, with Apple claiming ten hours for Internet browsing, and eleven hours of iTunes movie playback. Apple claimed nine hours of Internet browsing or ten hours of iTunes movie playback. It uses a new 39.7 watt-hour lithium-polymer terraced battery cell which was advertised to provide "all day" battery life. The battery was custom-designed to fill the available space in the small enclosure. The aluminum enclosure was 13.1 mm at its thickest point at the hinge end. A similar technology (3D Touch) is also used in the Apple Watch and introduced with the iPhone 6S. The trackpad was later brought to the Magic Trackpad 2 and the 2015 MacBook Pro. It also introduced the Force Touch trackpad, a solid-state trackpad that measures pressure sensitivity, and replicates a click with haptic feedback. The keyboard's backlight no longer consisted of a row of LEDs and a light guide panel, but instead used a single LED for each key. The MacBook introduced a new Butterfly keyboard, with traditional scissor mechanism keys replaced with a new, Apple-designed butterfly mechanism, making the keyboard thinner and, as Apple claims, individual keys more stable. ĭespite its small size, it features a full-sized keyboard and a large trackpad. Shortly after the MacBook's introduction, various companies began announcing cables and adapters for the USB-C port. Thunderbolt devices, such as storage media and the Apple Thunderbolt Display, are not compatible. It was one of only two Macs, along with the 2012 Mac Pro, to not support Thunderbolt since it was introduced to Macs in 2011. Although Thunderbolt 3 technology uses USB-C connectors, the MacBook's USB-C port does not support Thunderbolt. Apple markets an adapter that can provide a full-size USB connector, and a "Digital AV Multiport Adapter" with a charging pass-through, full-size USB port, and HDMI output. The port supports transmission speeds of up to 5 Gbit/s, and can be used for data, and audio/video output, and charging it was the first MacBook without MagSafe charging. The MacBook has only two ports, a 3.5 mm headphone jack and a single, multi-purpose USB-C port it was the first Mac with USB-C.
