Apple fed back about this battery drain issue say that it ’s normal demeanour after an update because the operating scheme do background operation , such as optimise your data and scan your photo library using update machine scholarship algorithmic program .

On 8 February Apple annunciate that iPhones will be able-bodied to serve as US Post Office terminal in the future . The function , referred to by the maker as Tap to Pay , had corresponding APIs in the iOS 15.4 beta that developer can tailor-make for their apps and military service . Access to the armed service requires registration with Apple ’s Apple Business Register portal vein . water faucet to bear is quite universal – in summation to NFC - enabled iPhones and credit card , coupon cards and workshop cards are also supported . However , it does seem that Tap To give will ab initio be US only , so it stay to be learn how it will apply elsewhere in the world .
Push notifications in Safari
The iOS 14.4 beta suggest that Apple is work on a Modern push API for iOS and iPadOS that will make pushing notifications possible in Safari . While Apple has been allowing push notifications via Safari on Mac for year , so far it has turn down to bring in the function to its mobile equipment .
Maximiliano Firtman discovered two observational WebKit functions in the iOS 15.4 beta that point the arrival of World Wide Web push and web notifications and flagged them in his blogfirt.dev . The two skidder – integrate web notifications and drive API – are disable by default and do not yet work , but he suspects that they will finally .
This should mean that websites can ask if you desire push notifications on your mobile .

Request for Siri recordings
Back in August 2019 it egress that Apple was record some Siri requests and using third parties to judge them . Worse still , this valuation was not sufficiently communicated to the user , so the account get outrage . Hence forth Apple as asked users explicitly for permission to make these recordings ( that are intend to improve Siri ) and Apple has promised not to hand over such data - sensitive information to external companies .
However , the genus Beta of Io 15.4 has uncover a bug that was causing some of these Siri requests to be hive away on some iPhones despite users ’ rejection . It seems that the mistake be in iOS 15 to iOS 15.1.1 . Then with iOS 15.2 in December 2021 Apple fixed the mistake by intercept such recordings happen on touch devices .
With Io 15.4 ( presently in the 2nd genus Beta ) , the equipment will again to require for permission for Siri evaluations , but this will be only for those user for whom Apple stopped Siri recording in December 2021 . So if you see this petition it indicates that your recording were being saved .
Apple has substantiate toZDnetthat all record resulting from this misplay have been deleted .
