There are two "dangers" from tight loops. One is just the fact that you are bending wires, and if you bend them too tight then can "kink them", and as you bend them back and forth you can weaken/break them. The same as if you would any piece of metal.
The second danger is electrical and only applies to when you are charging. As the current flows through a wire, it introduces a magnetic field. A magnetic field in turn can induce a current in another wire. Crossing wires can therefore setup a situation where the induced current might get large enough to affect the current in another wire that can lead to heating or more power draw, or both. Also, just current flowing through a wire generates heat and the more current the more heat, and you need to space out that heat so it doesn't melt the insulation.
But it is important to realize a few things. First off, the shield cables for this very reason (a ground around the wires to block the magnetic field). This is especially important to the data lines, which would be much more sensitive to this because they have lower voltages on them and higher speed signals.
Also, the thicker the cables the larger the loops should be.
I think @Mach-Lee 's images are great examples of proper improper. This isn't a garden hose.
