When evaluating controllers, prioritize Bluetooth 5.0 or higher for low-latency connectivity and a battery capacity of at least 600-1000mAh to ensure 6-10 hours of continuous playtime. For high-end or 'Pro' models, verify the inclusion of Hall Effect joysticks, which use magnets to prevent 'stick drift,' a common failure point in traditional potentiometers. Additionally, ensure the haptic feedback motors and adaptive triggers (for PS5-compatible models) meet OEM performance standards to guarantee user satisfaction.
