As Niel suggests, yes, normal. You might benefit from reading about Battery Health, so read this --> Battery Health Decline - Should You Worry… - Apple Community


I will say that you must be a heavy user to go through 54 cycles in one month. Your battery should stay normal up to 1000 cycles. When the health dips to 80%, it will be time to replace the battery. At that rate: 1000/50 = 20, which means you will likely be looking at needing to replace the battery in your iPhone in about 20 months.

It's normal for the battery in an iPhone 15 or newer to lose 1% of its health every two months or 50 charge cycles on average; the displayed percentage is approximate in any case.
