iPhone SE battery drain overnight

Hi Peps,

do you notice the iPhone SE battery draining overnight from 70% to 0% died.

I haven’t seen this bad idle standby battery draining with previous iPhone 7+ (which was with low 78% battery life).

this is my 2nd day using this new iPhone SE. I saw the similarities in both days. I’m worries about this device. Can Apple help me with this please?
