The Xiaomi SU7 battery retained 94.5% of its capacity after 265,000 km

The owner of a Xiaomi SU7 electric vehicle shared unique data on the battery's health after 18 months of intensive use, covering 265,000 kilometers. Official testing at a Xiaomi service center confirmed that the battery retained 94.5% of its original capacity, representing only 5.5% degradation over this period. The 94.3 kWh battery completed approximately 506 full charge cycles, demonstrating exceptional wear resistance even under extreme loads exceeding the annual average for most electric vehicle users.

These results significantly exceed standard automaker warranties, which typically allow for 20-30% battery degradation over 8 years or 150,000 kilometers. By comparison, Tesla guarantees at least 70% capacity retention after 160,000 kilometers. The Xiaomi SU7's performance is particularly impressive under heavy use—the average daily mileage was approximately 500 kilometers, exceeding the typical operating conditions for personal electric vehicles.

An additional inspection revealed the excellent condition of other key components—the brake pads did not require replacement during the entire period, and the coolant maintained its original characteristics with no signs of wear. The owner plans to continue intensive use with the goal of reaching 600,000 kilometers within three years, documenting all changes to the vehicle's condition.
