iOS 9: new features for the iPhone and iPad notification center

Even if the visible new features brought
by iOS 9 are not as important as in previous years, it is
some which should make our lives easier, particularly in the
notification center.

With iOS 9, notifications will be easier to delete and we will see
even arriving some new widgets:

One of the most common user complaints related to this
notification center is that it is impossible to delete all the
notifications all at once. In iOS 9, alerts are arranged by default according to
their order of arrival. In this case, the user can choose to delete
all the notifications arrived during a day with a simple click
or the number of apps concerned.

Although there is still no way to delete everything at once, here it is
already a step in the right direction. For those who would like to do it the old-fashioned way
classifying notifications by apps, it will always be possible by passing
take a look at the settings.

The other new feature concerns Apple Watch users who will be able to
choose to display in the today tab, a widget showing the percentage
remaining battery. Find My Friends also gains a widget to find
his friends easily.

On the iPad side, the notification center gains a very practical landscape mode which
takes advantage of the entire screen and thus allows the tab to be displayed
'Today' and notifications at the same time.
