iPhone 17 Pro vs Galaxy S26 Plus vs OnePlus 13: Key Slim Case Differences
iPhone 17 Pro (149.6 x 71.5 x 8.25 mm) slim case: MagSafe passthrough at 25 W, titanium frame aesthetic compatibility, Desert Titanium colorway. Galaxy S26 Plus (157.8 x 75.8 x 7.3 mm) slim case: 25 W wireless, Samsung wallet magnetic attachment, ultra-slim 7.3 mm phone base creates remarkably thin total profile. OnePlus 13 (165.6 x 76.0 x 8.9 mm) slim case: alert slider cutout, 50 W AirVOOC passthrough, tallest of the three at 165.6 mm. The slim series uses 0.33 mm back panel across all three — the difference in total case thickness is driven entirely by the device's own dimensions.
The Gorilla Cases Slim Series Across All Three
All three share: 0.33 mm frosted matte back, 1.5 mm raised camera lip, 0.8 mm raised screen lip, tactile volume and power buttons, wireless charging passthrough, flexible TPU with anti-yellowing UV resistance, and drop protection up to 4 feet on flat surfaces. The MagSafe passthrough is exclusive to the iPhone 17 Pro version — Galaxy and OnePlus versions do not have embedded MagSafe ring magnets.

Which Phone Has the Best Slim Case in 2026?
If MagSafe accessory ecosystem matters: iPhone 17 Pro slim case is the choice — MagSafe wallets, PopSockets, ring stands all attach through the slim case. If ultra-thin total profile matters: Galaxy S26 Plus slim case at 7.3 mm bare creates the slimmest phone-plus-case combination of any flagship in 2026. If charging speed through a slim case matters: OnePlus 13 at 50 W AirVOOC is the fastest wireless charging through any slim case in this comparison.
Alert Slider Cutout on the OnePlus 13 Slim Case
Unlike the rugged series, the slim case presents a more challenging tolerance question: a 0.33 mm back panel leaves less material for the alert slider aperture housing. The Gorilla Cases OnePlus 13 slim case solves this with a reinforced aperture ring — 0.8 mm border thickness around the 4.2 mm slider aperture — maintaining structural integrity without adding bulk at the upper-right corner.
