Every time you share content on the iPhone, Siri likes to make suggestions. These suggestions are the best guess from iOS about which of your contacts you'd like to share with, as well as what apps you can use to share. While Siri's suggestions can be helpful, sometimes the suggested contacts are incorrect. The share sheet can also become cluttered, which is why contact suggestions can be disabled.

Over time the iPhone connects to many Wi-Fi networks, which are stored for future use. After all, this is how the iPhone can reconnect to a known hotspot automatically. iPhone owners can stop this by switching off auto-join, or forgetting a network altogether. There is also a way to see the list of stored Wi-Fi hotspots in iOS, delete networks from the list, and even view their passwords.

One of the most power-hungry components on an iPhone is the screen. Battery life on the iPhone is naturally extended by turning off the screen whenever possible. This is why the device is normally set to auto-lock after a minute or two. Many iPhone owners don't bother to manually lock, so this feature keeps our devices secure as well.
