5 Reasons the Xiaomi S40’s Longer Battery Matters for Large Homes

The S40 runs 150 minutes per charge, while the H40 lasts only 100 minutes. That extra 50 minutes is critical for homes over 1,000 square feet.

With the H40, you often need to recharge mid-clean in larger spaces. The S40 can finish a full pass without stopping.

A mid-clean recharge adds 2–3 hours to your cleaning time. The S40 avoids that delay entirely.

The S40’s battery handles multiple rooms or floors in one go. The H40 may struggle to cover even a single large floor plan.

For smaller homes under 1,000 square feet, the difference is less noticeable. But for larger layouts, the S40’s longer runtime is a practical advantage.
