Vivo V11 Pro does support the fast charging. It takes just about 30 minutes to charge from 0% to 42% and about 60 minutes to charge the battery from 0% to 80%. You need to use the supplied original charger for the best results.
The Vivo V11 Pro is a solid all-rounder at Rs. 25,990 and offers better value than the Oppo F9 Pro (Review), but for a bit more money. Think of it as a Vivo X21 with a bigger battery and better front camera, but at a much more reasonable price, which is a good recipe.
