The Honor X9c, equipped with a large 6,600mAh silicon-carbon battery, has achieved top rankings in DxOMark's battery tests, showcasing the advantages of this emerging technology.
Until recently, smartphone batteries exceeding 5,000mAh were rare. However, silicon-carbon batteries are changing this, offering benefits such as higher energy density and improved longevity. While silicon recycling is not yet commercially widespread, these batteries represent a substantial leap in smartphone battery technology.
Impressive Battery Life
The Honor X9c's high energy density allows for a substantial battery capacity within a lightweight and slim design (189g). DxOMark's testing highlights its impressive battery life:
- Talk time: Over 42 hours
- Video playback: 29 hours
- Gaming: 15 hours
- Moderate usage: Up to four days
- Heavy usage (7 hours/day): Over two days
Charging Performance
The Honor X9c supports 66W fast charging via USB-C, achieving a full charge in just over an hour and reaching 80% in approximately 42 minutes. While not record-breaking, this speed is commendable considering the battery's large capacity. This compares favorably to the Apple iPhone 15 Pro Max, which takes over two hours to fully charge its smaller 4,441mAh battery.
The Honor X9c's performance demonstrates the clear benefits of silicon-carbon battery technology in terms of both battery life and charging capabilities.
