• “I want to make sure if this is normal for this time period or if there might be an issue with the battery.”

Your battery is likely doing better than average.


Normally, the battery will decline about 1% for every 40-50 charge cycles.....regardless of the age of the battery.


Keep in mind that Apple expresses battery performance in an unusual way. The never show a "tenths" of a percent and instead round down the number to a whole number.


For example, the battery might really be at 98.9%, but this will be displayed as 98%. So what looks almost like a 1% decline might really only be a .1% decline.
