OnePlus 12 Battery health down to 98%

My OnePlus 12 battery health reduced to 98 % yesterday. Bought my device on first sale Jan 30th On April 27 it reduced from 100 > 99 And yesterday June 27 its down to 98%

Many said that 1% reduce every 3 month is good, but it seems mine just reduced 2% within 5months. So, Any other recommendations for good battery health?
