Frequently asked
Is the X Fold5 supported in 2026?
Yes, fully. Released in mid-2025 with a four-OS, five-year security commitment, it is early in its support cycle and will receive updates well into the 2030s.
How long will the X Fold5 last?
With the Snapdragon 8 Gen 3, a large 6000mAh battery, and support running to 2030, the main limiter is hinge and screen longevity rather than software, giving it a strong multi-year lifespan.
How long will the Vivo X300 Ultra be supported?
Vivo hasn't published a separate written policy specific to the X300 Ultra at the time of writing, but based on the X300 and X300 Pro's official 5-year OS/7-year security commitment, buyers can reasonably expect the same, projecting support into around 2033.
Is the X300 Ultra sold in the US?
No. It launched in China in March 2026 and expanded to Europe, India, and parts of Asia and the Middle East by May 2026, but Vivo has not brought it to the US market, so any US unit is an import without official warranty.
