Z80 Ultra vs X300
Winner
Vivo X300
Lifespan decides this one: the X300 is supported until Oct 2032 at $9.32 per month of safe use, while the Z80 Ultra runs out in Oct 2028 ($25.32/month). On a which-lasts-longer question, that's not a tie — it's the whole answer.

Frequently asked
When does the Nubia Z80 Ultra stop getting updates?
Nubia and parent ZTE make no clear multi-year update promise. In practice their flagships have often received only one to two Android upgrades and a couple of years of patches. We estimate around 2 OS updates and roughly 3 years of security support from its October 2025 launch (into about 2028), which is shorter than most mainstream flagships, so buy it for the hardware, not the software timeline.
Is the Nubia Z80 Ultra worth buying in 2026?
For the price it is one of the best hardware bargains around: a Snapdragon 8 Elite Gen 5, a 7200mAh battery, a genuine periscope zoom and an under-display camera for well under $750. The trade-offs are Nubia's rougher software and short update support, so it suits enthusiasts and value hunters more than someone who wants years of guaranteed updates.
How long will the Vivo X300 be supported?
Vivo has officially committed to 5 major Android OS updates and 7 years of security patches for the X300, dating from its October 2025 launch. That pushes its end-of-support date out to roughly October 2032, making it one of the longest-supported compact Android phones on the market.
Is the Vivo X300 available in the US?
No. Vivo does not sell the X300 through official US channels, so any US unit is a gray-market import without manufacturer warranty or guaranteed full-band 5G support on US carriers.
