Most people purchase a new iPhone, or indeed any tech product, and they leave the settings set to the defaults laid down by the manufacturer. This is a perfectly acceptable routine and no problems are likely to appear because of this, but there are times when you can change the defaults to offer a much more positive experience. These changes will bring incremental improvements, but together they should give you an iPhone that feels a little snappier and which is easier to use throughout each day. The latest iPhone 13 devices are perfect fodder for tweaking because the software and hardware are as complex as can be found in any iPhone, and this gives you the opportunity to make them more suitable for your needs.
