There is something poetic about endurance.
Not the loud kind that brags, but the silent one that simply keeps going.
In the fast-moving world of electric vehicles, battery degradation is often the biggest fear whispered among potential buyers. People ask the same question again and again: How long will the battery really last? And more importantly, what happens after years of daily use?
Surprisingly, the answer comes not from a laboratory, not from a marketing brochure, but from a long road traveled—265,000 kilometers long.
According to Carnewschina, a Xiaomi SU7 owner named Feng shared his real-world experience after 1.5 years (18 months) of intensive use. What he found was unexpected, even to himself. He thought his battery health had fallen to around 90 percent. Instead, the data showed 94.5 percent.
That number is not just impressive—it is reassuring.
The vehicle in question is the rear-wheel-drive Xiaomi SU7 Pro, equipped with a 94.3 kWh battery. Feng drives an average of 600 km per day, a distance comparable to a round trip between New York and Boston. This is not gentle usage. This is real life, demanding and relentless.
And yet, the battery endures.
For many readers considering switching to an electric vehicle, stories like this quietly answer the biggest doubt. Not with promises, but with proof.
Moreover, What Really Happens to an EV Battery After 18 Months?
Let us pause for a moment and look deeper.
Battery health degradation is normal. Every electric car battery loses capacity over time. The real question is how much, and how fast.
Based on Feng’s driving habits and an average energy consumption of 18 kWh per 100 km, the Xiaomi SU7 battery is estimated to have gone through approximately 506 full charge cycles. In reality, the number may be even higher because Feng often used partial charging (20–80%), a method widely recommended by EV experts to prolong battery lifespan.
Industry standards tell us that most manufacturers offer an 8-year warranty or 150,000–160,000 km, allowing for 20–30 percent capacity loss within that period.
Now compare that to this case:
-
Distance driven: 265,000 km
-
Battery health remaining: 94.5%
-
Degradation: Less than 10%
The contrast is striking.
This is not just a technical success. It is a psychological breakthrough for consumers who still hesitate. When a battery performs this well under extreme usage, it quietly reshapes expectations.
And there is another detail that matters—cost savings.
Feng shared that he saved more than 100,000 yuan (approximately IDR 240 million) in fuel costs compared to using a conventional car. That is not a future promise. That is money already saved.
For individuals, businesses, or fleet operators, this kind of efficiency changes long-term financial planning entirely.
Therefore, Why This Story Matters for Future EV Buyers
Every purchase decision begins with trust.
Electric cars are no longer just about innovation; they are about reliability, sustainability, and long-term value. The Xiaomi SU7’s real-world performance offers a concrete illustration of how modern EV technology has matured.
Although this data comes from a single vehicle, it represents something larger: confidence.
Confidence that:
-
Battery degradation is no longer as frightening as it once seemed
-
High-mileage usage does not automatically mean rapid battery decline
-
Proper charging habits truly make a difference
This story arrives at a crucial moment, just ahead of the next-generation Xiaomi SU7 launch in April. For potential buyers, it acts as a bridge between curiosity and commitment.
If you are considering:
-
Purchasing an electric vehicle
-
Transitioning your business fleet to EVs
-
Using EV charging optimization services
-
Consulting battery health monitoring or EV maintenance providers
Then real stories like this are not just informative—they are persuasive.
Choosing the right EV services, charging solutions, and long-term maintenance partners will determine whether your experience mirrors Feng’s success or falls short. Smart decisions today create savings, durability, and peace of mind tomorrow.
Sometimes, the best stories are not loud.
They simply last.
And in the quiet endurance of a battery after 1.5 years and 265,000 kilometers, the future of electric mobility feels a little more certain.
