My iPhone 12 battery capacity dropped in 5 days from 100% to 97%

I have an iPhone 12 since March 2023 and for 6 months the battery capacity was at 100%. But suddenly about 5 days ago the capacity dropped from 100% to 99%. Another 1-2 days went by and it dropped to 98% and today it dropped to 97%. What could be causing this and should I take it in for service?

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.
