Should I replace my iPhone 8 battery if the health is at 68%?

My iPhone 8 Battery Health shows 68% as the Maximum Capacity.

I bought it as a second-hand device so not sure if the battery is already the default one or not.

I'm OK with the iPhone now but some people told me to replace my battery as it this way may damage the internal segments. Is it true and should I now replace my battery, please?

Thanks

You should have Apple or an Apple Authorized Service provider replace the battery once the Battery Health drops below 80%.

My iPhone sent me a notification, and put up a permanent message in Settings when that happened. I scheduled an appointment with an Authorized Apple Service provider. They replaced the battery and had the phone back to me later on the same day that I dropped it off.
