This is how iOS 9 will revive iPhones, iPads with 8 and 16 GB of memory

Theyesterday's conferenceby permission of
confirm some of the indiscretions that had preceded it. So, iOS 9 is
a version which brings relatively few new features, Apple having
favored the optimization and improvement of the existing system. A breath
probably necessary after two versions iOS 7 and iOS 8 which had brought
many new features.

Among the optimizations, some are aimed directly at users
of machines with a small storage space, but it will please others
also :

Thus, Apple engineers worked on optimization in terms of
consumption of storage space. We have seen it in recent years, iOS
had swelled to the point of being sometimes difficult to update on certain
machines. For their part, apps have also grown steadily over time.
as new machines and resolutions are added within the
range.

So Apple worked on the subject and generally offers three
improvements with the next version of its mobile system.

A lightweight iOS

First of all,the place occupied by iOS 9 has melted!

In fact, we go from4,58 Go pour iOS 8at a measly 1.3 GB
…

It ismore than 3 GB of disk spacewhich will thus be rendered
to the user. Perfect for storing apps, content but also
practical during OS updates which will be faster, less cumbersome to
retrieve and easier to fit into the remaining memory space.

But that's not all!

Less demanding apps

Beyond the OS, these are the applications that will take a cure with iOS 9
slimming. This is the “thinning app” unveiled yesterday during the conference.

To reduce the space occupied by apps, several optimizations have been made.
been developed.

First of all, rather than embedding images intended for all
machine sizes, or even code intended for a 64 and 32 bit processor,
only the resources necessary for the machine used will be
stored in the appduring their installation. For this, the
developers will have to carry out some manipulations but they seem very
reduced, they will continue to load their apps as before for the update
available on the App Store.

Thus, a universal app installed on an iPhone 5c, although compiled
for 32 and 64 Bits, will not need to integrate the X3 images from the iPhone 6
Plus, those of the iPad or the 64-bit code intended for recent machines
in his code.

This is so much space saved and it should be significant, the graphs
mentioned a 40% space saving yesterday during the presentation!

• A technique to read
  here on the Apple developer portal

Asecond technique(On Demand Resource) will allow
also reduce the size of applications.

This will be in the hands of the developers, who will be able to choose a
a certain number of elements within the apps, to be loaded later, when there are
needs.

The best example is a game, in which the first levels are
available for installation, but the following levels will not be
downloaded only when the player needs them. Better, the levels already
past times can eventually be cleared from memory. We imagine that the gain
can be also significant! Conversely, for a long plane trip,
there might be some levels missing...

We see, everything is done so that the precious memory bytes of our
machines are used to their best advantage. And this even on the most
old sinceiOS 9 remains compatible with iPhone 4s or iPad 2
2011notably.

A fine example of development whichdoes not provide functionality
visible, but will undeniablyserve everyone
daily!
