The Mous wins at 4.2 by having no weak category. It finished fourth in both
drop tests, holds the phone at 13.4 lb, gives the screen 1.22 mm of clearance,
and — uniquely here — adds essentially nothing to button force, needing 20 oz
against the bare phone's 19. That last point matters more day to day than any
drop rating, because it is the thing you touch a hundred times. Its MagSafe is
merely adequate at 4.15 lb, and at $85 it is the most expensive case tested.
The value case is not close: the $27 ESR won the side-impact test outright,
tied for first in corner impact, and was the only case in the group still
showing minor damage after a 42-inch corner drop — a height that destroyed
everything else. It also has the deepest screen bezel at 1.52 mm. Two real
caveats: at 78.62 g it is a big case with stiff buttons, and it grips the
phone the least of anything tested at 6.6 lb. The Rokform is the pick if
protection is genuinely the only criterion, tying ESR for first at 30 inches,
but it is the heaviest case here at 86.36 g.
The most useful finding is how badly price predicts protection. Both $50 cases
finished near the bottom: the Apple placed 15th of sixteen in side impact with
one of the shallowest bezels in the group, and the OtterBox's corner folded
under a 24-inch drop, took 47 oz to operate its buttons, released the phone at
just 4.3 lb, and was the only case that blocked wireless charging. Meanwhile
the $21 Miracase finished third of sixteen for corner protection, ahead of
every premium case except the two winners. And the baseline holds throughout:
a bare phone dropped from 24 inches was in worse shape than any cased phone
dropped from 30.
