Microsoft Surface Book 3 15 (2020) — the detachable with a big battery and a reliability flag it earned
The Surface Book 3 15 at $566 is a 2020 detachable convertible with a Core i7 1065G7 and 32 GB of RAM. Battery capacity is the flagged strength at 82 Wh — 51.9% above the class median — while reliability is the flagged weakness at 24, half the class median of 49. Mobility reads 41 (−39.7%), a mid-band miss for the format.
Where it holds up
The 82 Wh battery is the honest headline: the biggest cell in this batch's convertible set alongside the 80 Wh Yoga Book 9i. Photo design reads 35 (mid) and portability 48 (mid) — the 15-inch detachable compromise. The 32 GB ceiling doubles the class norm, and the tablet detachment still differentiates the design.
Where it falls short
Reliability at 24 (low) is the flag that matters at six years old — the hinge and detachable mechanism are the wear points to inspect. Overall performance reads 28.48 (low) with gaming 23, modeling 19 and CAD 22 at the integrated floor. Value lands 15.5 (low). No depreciation anchor is recorded (base $0); the 2020 cohort rate is 10.38% per year.
Price and depreciation
No curve or projection applies without an anchor; the 10.38% class rate is largely played out. At $566 the ask reflects the format's collector value as much as its compute.
Alternatives to consider
The Surface Book 3 13.5 at the same $566 in this list is the smaller sibling with a GTX 1650 aboard and portability 68.3 high; the Yoga 7i 15 (2020) at $566 is the conventional convertible at the same price; and the Surface Pro 8 at $666 is the newer tablet route.
Bottom line
Fairly priced for the class. A battery-first detachable: 82 Wh and 32 GB of RAM against reliability 24 low and performance 28.48 low. Buy it for the format and the endurance; inspect the hinge before buying at all.
