OPPO F31 Pro Plus Battery and Charging Features
The phone’s endurance is powered by a massive 7000mAh silicon-carbon battery, designed for users who consume media, play games, or work remotely without frequent charging interruptions. Paired with efficient hardware and ColorOS’s smart power-saving technologies, this battery comfortably provides a day and a half of moderate to heavy use.
Charging is handled via 80W SUPERVOOC Flash Charge technology, which rapidly charges the battery to approximately 42% within 20 minutes and can fully charge the device in around 40-45 minutes.
