My iPhone 13 was bought second hand but I got the battery replaced and in January 2025 it was on 100% however we are in April and it’s on 95%.
Does anyone know how to help?

iPhone 13, iOS 18
On an iPhone 13, it is not unusual for it to lose 1% per month. More specifically it is 1% for every 25 charge cycles for a total battery life of 500 charges cycles, but the cycle count is not readily available on an iPhone 13 so using the monthly average is more common.
I assume you got the battery replaced at Apple or Authorized Apple Seller as the numbers provided only pertain to genuine Apple batteries.
If you find yourself needing to charge your phone multiple times a day, then review the apps that are consuming your battery at Settings > Battery and scroll down to see usage over the last 24 hours. Some apps are notorious for using vast amounts of battery power even when they are not being used. This is done through the use of Background Processes and testing by removing the highest offenders may have a significant impact on how often you need to charge your phone, which reduces your cycle count.

Battery draining percentage depends on the usage of Apps and browsing time of the device.
if the battery is reduced to less than 80% then you need to replace the battery .
How long should an iPhone 13 battery last after replacement?
