: Freeing up space (keeping at least 10–15% empty) allows the system's TRIM command to work efficiently.
Modern Android devices do not use HDDs. They use Flash storage, specifically eMMC or UFS chips. These are Solid State Drives (SSD) with no moving parts. In a Flash-based system, the time it takes to access data is the same regardless of where it is stored. Therefore, moving files around to be "next to each other" provides zero performance benefit. The Risks of Defragging Android
Technically, defragmenting flash memory is not only unnecessary, but it can actually be harmful. It causes "write cycles" that can degrade the lifespan of your storage chip over time.
