How Fast Charging Works
Fast charging adjusts voltage and current intelligently based on:
- Battery temperature
- Battery percentage
- Charger capability
- Cable quality
- Power management chip
Modern devices use smart controllers to protect the battery from overheating.
2. Wireless Charging
Wireless charging uses electromagnetic induction coils to transfer power without a cable.
How It Works
- The charger coil generates a magnetic field
- The smartphone coil receives it
- The battery converts it into charge
Wireless Charging Standards
| Standard | Max Power Output | Technology Used |
|---|---|---|
