There has been a lot of confusion regarding some of the specifications of the Galaxy S26 series. First, the company clarified that its new high-end phones do not use native 10-bit OLED panels. Now, it has released official information about the UFS version of the storage chips used in the Galaxy S26 lineup.
Samsung has confirmed to us that all variants of the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra use UFS 4.0 storage chips. Some reports suggested that the Galaxy S26 Ultra uses UFS 4.1 storage, while others claimed that the 1TB version of the phone uses UFS 4.1 storage. However, according to Samsung, that is not true.
If you are disappointed after reading that the Galaxy S26 series uses UFS 4.0 storage instead of UFS 4.1, you should know that based on JEDEC standards, there is no difference between UFS 4.0 and UFS 4.1 standards in terms of data transfer speeds. Both standards share the same MIPI M-PHY 5.0 and UniPro 2.0 specifications, which means both offer a theoretical interface bandwidth of up to 23.2Gbps per lane (around 4.2GB/s for a 2-lane device).
While UFS 4.1 is slightly more efficient than UFS 4.0, it remains unclear how much of a difference it makes to the overall battery life of phones, as a storage chip consumes very little power in a smartphone. Other components, like the display and the processor.
