Simply express the charging speed of VOOC flash charging technology through numbers, not specific instructions. After charging for 5 minutes, the power can reach 20%. This speed is really fast, just like forgetting to charge at night, brushing your teeth and washing your face early can basically be done. OPPO is really powerful.
