Why does Auto-Lock exist on the iPhone?

So now that you know Auto-Lock is a feature that automatically locks your iPhone, why does an iPhone do it though? Almost all smartphones do this and there are a few reasons.

One of the reasons is that it is done as a security measure because if your iPhone is unlocked and if you are not near it, there’s a chance that people might snoop or do something malicious. So if your iPhone Auto-Locks itself, it will be safe even when you are not near it.

Another reason for your iPhone Auto-Locks itself is to preserve battery life. When your iPhone Auto-Locks, the screen goes to sleep as well and suspends the background tasks, this will save battery life. So if you were using your iPhone and maybe fell asleep, it will auto-Lock after some time to save battery life.
