Canon Speedlite EL-5 Battery Draining

[Skynet-T800]

Just received mine and was shocked to see that it drains the battery overnight when turned off?

Not owned a Flash since the Nikon SB-800 some 10 years ago.

Anybody got one of these and experiencing the same issue?

Other than that the flash is amazing but cba pulling the battery out after every use!

I'm a Nikon user with no clue about Canon but I would suggest returning it.
