VIVO uses proprietary fast charging technologies like FlashCharge, Super FlashCharge, and Dual-Engine Flash Charge. These systems leverage high-wattage charging (up to 120W), intelligent temperature control, and dual-cell battery designs to achieve ultra-fast charging speeds. For example, VIVO’s 120W FlashCharge can charge a 4,500mAh battery to 50% in 5 minutes while ensuring safety through 12-layer hardware protection.
How Does VIVO’s FlashCharge Technology Work?
VIVO’s FlashCharge employs a 20V/6A configuration (120W) to split power between two 2,250mAh battery cells via a patented dual-charging chip. This reduces heat generation by 40% compared to single-cell designs. The system uses customized charging cables, a 98% efficiency conversion rate, and real-time temperature monitoring to prevent overheating during charging.
What Are the Differences Between FlashCharge and Super FlashCharge?
FlashCharge (120W) focuses on maximum speed for flagship devices, while Super FlashCharge (80W) balances speed and battery longevity. The 80W variant uses a 20V/4A configuration with optimized charging curves to reduce lithium plating. Independent lab tests show Super FlashCharge preserves 85% battery health after 800 cycles, compared to 78% for 120W FlashCharge.

Which VIVO Phones Support 120W Fast Charging?
Current 120W FlashCharge models include the iQOO 7 series, VIVO X80 Pro+, and iQOO 9 Pro. These devices feature specialized 10C-rated batteries with graphene-enhanced electrodes for faster ion movement. Compatibility requires using VIVO’s original 120W charger and 1.5-meter Type-C cable containing 21 temperature sensors for safety regulation.
How Does VIVO Ensure Battery Safety During Fast Charging?
VIVO implements 12-layer protection including overvoltage safeguards, graphene cooling films, and a voltage stabilization algorithm. Their chargers have TÜV Rheinland certification for 876,000 charge/discharge cycle safety. The battery management system (BMS) adjusts current flow 500 times per second based on real-time temperature data from 14 internal sensors.
“The multi-stage protection system acts like a digital nervous system, responding to microsecond-level voltage fluctuations before they become dangerous,” explains VIVO’s Chief Battery Engineer Zhang Li.
Recent advancements include phase-change cooling materials that absorb 3J/mm³ of thermal energy during peak charging. The dual-cell design distributes heat across 58% more surface area compared to conventional batteries, while the adaptive charging algorithm skips voltage steps that cause excessive heat. Third-party testing reveals VIVO’s safety system triggers protective shutdowns 0.8 seconds faster than industry average responses.
| Protection Layer | Function |
|---|---|
| Overcurrent Defense | Limits current to 6.5A max |
| Dielectric Shield | Prevents electrolyte leakage |
| Voltage Stabilizer | Maintains ±25mV fluctuation |
What Future Fast Charging Technologies Is VIVO Developing?
VIVO has demonstrated 200W wired charging prototypes charging 4,000mAh batteries in 8 minutes. Their 2024 roadmap includes gallium nitride (GaN) chargers with 97.5% efficiency and 50W wireless charging using magnetic resonance coupling. Patent filings reveal work on solid-state battery integration achieving 500Wh/L energy density for 15-minute full charges.
The upcoming 200W system utilizes a triple-chip architecture that divides current into three 66.6W streams, reducing individual component stress by 40%. Wireless charging developments feature dynamic frequency tuning that maintains 89% efficiency at 8mm coil misalignment. VIVO’s solid-state prototype shows 92% capacity retention after 1,200 cycles in laboratory conditions, with plans for commercial deployment by 2026.
- Can I use VIVO fast chargers with other phone brands?
- VIVO chargers support standard PD 3.0 charging at 18W for non-VIVO devices. Full 120W functionality requires compatible VIVO/iQOO phones with specialized power management ICs.
- Does fast charging work with wireless charging?
- Current VIVO devices support 50W wireless FlashCharge using custom magnetic alignment coils. This requires the VIVO Wireless Flash Charger Stand with active cooling fans.
- How does temperature affect VIVO’s charging speed?
- The system reduces wattage by 30% at 35°C and 50% at 40°C. Below 15°C, it preheats batteries using reverse current before initiating fast charging. Optimal range is 20-30°C for maximum speed.
