Frequently asked
When does the iQOO 15 Ultra stop getting updates?
iQOO backs the iQOO 15 series with 5 major Android OS upgrades and 7 years of security patches, so a unit bought at the February 2026 launch is covered until roughly February 2033. That carries it from Android 16 all the way to Android 21 and is one of the longest support windows on any performance-focused Android phone, comfortably beating dedicated gaming handsets that typically stop at two or three years.
Is the iQOO 15 Ultra worth buying in 2026?
Yes, if you want maximum performance and plan to keep the phone. Even midway through 2026 you still have around six and a half years of security coverage ahead, the Snapdragon 8 Elite Gen 5 will not feel slow for years, and the 7,400mAh battery ages gracefully. The main caveats are the 227g weight and the import-only availability outside China.
What sensor does the Vivo X100 Pro main camera use?
It uses a 1-inch-class Sony IMX989 50MP main sensor tuned with Zeiss optics.
Does the X100 Pro support wireless charging?
Yes, it offers 100W wired and 50W wireless charging.
