Electric vehicles are often questioned for their long-term reliability, especially when it comes to battery life. However, a real-world case from China is now reshaping this perception. A Xiaomi SU7 Pro electric sedan has clocked an impressive 2.65 lakh kilometres in just 18 months, while still retaining 94.5 per cent of its original battery capacity.
What makes this story remarkable is that the vehicle is not part of any company testing programme. It is privately owned by Mr. Feng, a daily commuter who uses the rear-wheel-drive sedan extensively. His usage averages nearly 600 kilometres every day, making the SU7 one of the highest-mileage examples of the model in regular civilian use.
Mr. Feng recently shared a detailed inspection report from a Xiaomi-authorised service centre on social media. The document highlights the strong performance of the car’s 94.3 kWh battery pack despite heavy and continuous use. Based on an estimated energy consumption of around 18 kWh per 100 kilometres, the car has completed approximately 506 full charging cycles.
Before the inspection, the owner himself expected noticeable degradation. Like many EV users, he assumed that such intense usage would reduce battery health significantly. “I thought it would be around 90 per cent at most,” he reportedly said. Instead, the results exceeded expectations, showing minimal loss in capacity.
The post quickly gained attention online, sparking discussions about electric vehicle longevity and real-world battery performance. Many users pointed out that the example demonstrates how modern battery management systems and thermal controls can help maintain long-term efficiency, even under demanding conditions.
Experts believe that consistent charging habits, controlled driving patterns, and advanced battery technology play a major role in preserving battery health. Xiaomi’s battery engineering, combined with careful usage, appears to have contributed to the impressive results seen in this case.
The SU7’s performance also adds to the growing body of evidence that electric cars can be dependable over long distances, challenging the notion that EV batteries degrade rapidly. For potential buyers who worry about long-term ownership costs and resale value, such examples offer strong reassurance.
As electric mobility continues to expand globally, real-life stories like Mr. Feng’s help bridge the gap between perception and reality. The Xiaomi SU7’s high-mileage success suggests that with the right technology and usage patterns, electric vehicles can be just as durable as their conventional counterparts—if not more.
