It can be much longer – depending particularly on the number of charging cycles the iPhone has clocked up.
But in your case there could be another factor: The iPhone X was introduced in 2017 and perhaps your 2021 replacement battery had been sitting in the Apple Store since then. A battery can degrade simply by being stored and not used.

I don't know, so I asked the free A.I. app ChatGPT:
An iPhone with a weak battery can seemingly recover some strength after it has been restarted. What could be a possible explanation for this?
When you restart an iPhone with a weak battery, it can temporarily appear to recover some strength due to the way the device’s operating system manages power and background processes. Restarting the iPhone stops any background apps and processes that might be consuming power excessively or inefficiently. This can provide a brief respite from battery drain, making the device seem like it has regained some battery strength.
Additionally, software glitches or bugs can sometimes cause abnormal power consumption. Restarting the iPhone can help reset these glitches and temporarily improve battery performance. However, if the battery is genuinely weak or degraded, the improvement will likely be short-lived, and the battery’s overall capacity will continue to diminish over time.
