Apple released iOS 11.2 earlier than expected due to a weird date bug that started crashing some iPhones on 2 December 2017. This bug has been fixed in iOS 11.2. Consequently, the software arrived unfinished and will probably need more tweaks over the coming days.
Apple has introduced a few new features including Apple Pay Cash which is a peer-to-peer money transfer service now available to users in the USA.
Apple Pay Cash to send, request, and receive money from friends and family within iMessage app or by asking Siri via Apple Pay account. Thankfully, Apple resolved that one quickly with the 11.2 update afterwards, but this one, pushed out of the gate as quickly as Apple could bake it, brought with it another share of problems, it seems, this time involving the latest and greatest iPhone X.
The new version of Apple's iOS is now available as an over the air update for the iPhone and iPad, and of course the iPod Touch. This facility is only available for users in the United States as of now.

Only when 600MB update is installed should users turn back on notifications. It also automatically notifies compatible devices to upgrade and will continue nagging users if they haven't already. The battery test is run using the new iOS 11.2 software, It is then compared to previous battery tests that were run on the same devices.
Apple would fix the Face ID issue formally in the next iOS update. For the meantime though, better stay clear of the update.
