Greenluma Steam Deck [2021] Jun 2026

All ports line up perfectly. The USB‑C port’s cutout is wide enough to accommodate the official Valve dock cable without removing the case. The headphone jack, micro‑SD slot, and power button are all accessible with a single press. Thumbsticks and face buttons retain their original click feel – no added friction.

| Test | Method | Result | |------|--------|--------| | | 3‑ft drop onto concrete (four corners, flat surface) | No visible damage, no functional issues. TPU absorbed impact. | | Heat Dissipation | 30 min of continuous gameplay (Elden Ring) at max settings | Surface temperature rose ~7 °C above the naked Deck; no thermal throttling observed. | | Button Responsiveness | 100 rapid presses on each face button, D‑pad, and thumbsticks | 100 % registration – no lag introduced by the case. | | Screen Visibility | Outdoor daylight (direct sun) | Screen protector’s anti‑glare coating helps, but brightness still limited by Deck’s native panel (as expected). | | Port Durability | Insert/remove USB‑C dock cable 30 times | No wear on port cutouts; case remained snug. | | Weight Impact | Benchmarked Steam Deck’s battery life with and without case (same game, same settings) | ~3 % decrease in runtime (≈ 20 min over a 10‑hour session) – negligible. | greenluma steam deck
