Apple iPhone will use QLC flash memory with lower lifespan/performance

According to foreign media reports, Apple will enable a larger storage design on the new iPhone released in 2026, which is expected to be 2TB. In addition, it is reported that Apple will use QLC NAND flash memory, possibly to control costs.

1. Changes in storage capacity

It is reported that Apple may change the storage capacity on iPhone 16. Instead of triple-level cell (TLC) NAND flash, quad-level cell (QLC) NAND flash is used on models with 1TB or more storage capacity.

2. Advantages of QLC flash memory

Compared with TLC, the advantage of QLC is that each memory cell can store four bits of data. Store more data than TLC while using the same number of cells, or use fewer cells to store more data. This can reduce production costs.

3. Disadvantages of QLC Flash

QLC Flash is considered less reliable than TLC Flash. The durability of written data is reduced because each cell is written more times because each cell contains one more bit.
