The R17 Pro's SuperVOOC charging is still among the fastest: 0 to 50% in ~10 minutes and nearly full in under 30.
-
VOOC 20W on the R17 and F9 series is no slouch either for everyday fast-charging needs.
Camera Capabilities
-
25MP front cameras across all three models make them ideal for selfie lovers.

The R17 Pro adds advanced low-light shooting with a variable aperture and night mode, while also featuring a dedicated ToF sensor (though limited by software).
Display & Design
-
AMOLED panels on the R17 and R17 Pro offer vibrant colors and deep blacks.
-
The F9 series features a waterdrop LCD and a more budget-oriented aesthetic.
Known Drawbacks

-
F9’s Helio P60 is decent for daily tasks but not meant for power users.
