Check Out How Much Faster Wi-Fi on the iPhone 6 Is

The iPhone 6 and iPhone 6 Plus are not only bigger than their predecessors—they’re faster, too. A Wi-Fi speed test by iClarified shows that the iPhone 6 Plus’s throughput speed is more than twice as fast as the old iPhone 5s.
The new iPhones boast a more advanced Wi-Fi standard called 802.11ac. On its website, Apple says the improved technology can provide for throughput speeds three times faster than older iPhones. However, users must have a router that supports 802.11ac to benefit from the speed boost.
