Iphone 11 pro max Battery

I charged my battery to 100%, it drained to 97% when i was using it and then again i put my phone on charge and it was settled there to get to 100% again.

The battery cycle on 10 May 2020 was 36 cycles , and even considering that i charged my device 3-4 times of 3% each time it makes 12 % not a complete cycle but to my astonishment , on 12 May 2020 the battery cycle count increased to 37

Please help out
