This information was published by respected foreign technology media The Verge. Although not mentioned in the article, the same features are likely to be added to the same generation iPhone XS Max.
This feature decreases peak speed to prevent the battery-degraded iPhone from suddenly turning off. Apple was considered a problem because it was built into iOS without notifying users, and criticized it for promoting the replacement of the old iPhone.
Due to the loan repayment, the company was forced to reduce battery replacement costs by nearly a year in 2018. In addition, iOS 11.3 and above can display "battery status" and the user can check that the performance management (device slowdown) feature is on and off. Please note that this feature is only enabled after the first sudden shutdown.
