It's your battery recovering charge after a start not your electrical system.
If your journeys are short and frequent, the battery won't recover sufficiently and in time will have a shorter life.
Just unlocking the car then leaving it without starting can place quite a large battery drain on really modern cars because so many systems "wake up" in readiness to be used and that's before you sit thumbing the manual with the radio on going through all the great things the car can do.
I always think of a battery as a bucket of water with a hole in it and how you use the car determines the size of the hole.
