Battery drain while using new IOS26 3D depth effect feature on lock screen

I slept with my phone battery with 33% and woke up with 21%. Before sleep, I turned off WIFI and put to airplane mode then put the display brightness to super low. I was not expecting the 11% battery drain overnight because normally I only get 2-3% drain. The battery setting says, the lock and home screen makes use most of the battery.

Is that the effect of the new IOS26 feature of the spatial depth effect on the lock screen? Or is this temporary since its newly launched?
