Rare, very strange what happened with iOS 11.2. Beta 5 was launched four days ago, beta 6 was launched yesterday, not even 24 hours ago, and today in Spain we see breakfast interrupted by the final version of iOS 11.2 available to everyone. I think I've never seen such an accelerated launch, especially with two very recent betas behind.
But the release is what it is, so we can all update this version in a stable and without problems. The download measures between 300 and 500 MB depending on the device you have and the official notes highlights the arrival of Apple Pay Cash in the United States. By the way, iOS 11.2 also fixes a very recent error that has appeared with notifications on some devices.
Faster wireless charging
iOS 11.2 also allows wireless charging of the iPhone 8 and iPhone X using a power of 7.5W. It charges like this faster than with the 5W cable adapter that comes with the iPhone, but slower than if we use the iPad's 12W adapter. For those who want to get rid of the cables, it is very good news.
A more discreet detail that opens with iOS 11.2 is a small line under the Wi-Fi signal and battery indicators of the iPhone X. It only appears on the lock screen, indicating that from there you can slide your finger down to invoke the center of control.
