A smartphone is powerful on its own, but with the right accessories, it becomes even more versatile, durable, and enjoyable. Whether you use your phone for photography, productivity, or streaming, certain add-ons can elevate the experience. While flagship phones like the HONOR 400 come fully equipped with cutting-edge features, complementing them with a few essentials can help you unlock their full potential.
Must-Have Smartphone Accessories for Everyday Use
Protective Case and Screen Guard
Your smartphone deserves protection from accidental drops and scratches. A high-quality protective case provides shock absorption without adding bulk. For slim devices like the HONOR 400—just 7.3mm thick and 184g light—a lightweight case maintains comfort while shielding the phone’s sleek, flat frame. Pair it with a tempered glass screen protector to guard the display against cracks. The HONOR 400 features a brilliant 5000nits HDR peak brightness display with 460PPI and 1.07 billion colors. A clear, scratch-free screen keeps visuals sharp, whether you’re watching Netflix HDR content or capturing stunning photos with the 200MP AI Main Camera.
Power Bank and Fast Charger
Battery life is a priority for every smartphone user. Although the HONOR 400 comes with a massive 6000mAh silicon-carbon battery that lasts all day and supports 80W HONOR SuperCharge, having a power bank is still smart for travel or emergencies. Choose a compact power bank that supports fast charging to match the HONOR 400’s performance. This ensures your phone stays powered during extended photography sessions, especially when using features like the AI Creative Editor or AI Power Film Simulation portrait mode, which rely on advanced processing and sustained power.
Wireless Earbuds or Headphones
Audio accessories are essential for calls, streaming, gaming, and voice commands. While wired headphones still serve a purpose, wireless earbuds offer freedom and convenience—especially on the go. Pair them with the HONOR 400’s AI Intent Recognition Engine for an immersive audio experience during video playback or while editing motion photos. For users who rely on their phones for productivity or content creation, high-quality Bluetooth headphones help block distractions and keep focus on the task.
HONOR 400 Features That Make Accessories More Useful
The HONOR 400 stands out with its 200MP Ultra-clear AI Main Camera, complete with dual OIS + EIS stabilization and a 1/1.4-inch large sensor. Whether you’re shooting at 15x or 30x zoom or enhancing facial detail with AI RAW models, this kind of clarity deserves support from proper accessories. A compact smartphone tripod helps stabilize shots, especially in low light. Pair it with a Bluetooth remote shutter to avoid blur during night photography or motion capture. With the HONOR 400’s AI Blur Calculation and large model clarity boost, even small adjustments in shooting setup can dramatically improve results. Some accessories enhance internal performance. While the HONOR 400 runs on the Snapdragon 7 Gen 3 Mobile Platform, which handles multitasking with ease, cloud storage subscriptions or microSD card adapters (if supported) help you offload large files from AI-enhanced videos and images. This is especially useful when using HONOR’s seamless sharing function—like transferring motion photos between phones or posting straight to social media. Having organized storage makes sharing and editing faster and more efficient. Streaming and reading feel better when the phone is propped at the right angle. The HONOR 400’s 120Hz refresh rate, AI Vivid Display Technology, and DCI-P3 Wide Gamut make video playback a visual treat. A sturdy phone stand enhances this by offering hands-free comfort for long viewing sessions.
Conclusion
Accessories don’t just protect your smartphone—they expand its functionality and improve your overall experience. Whether it’s a case to preserve its elegant design, a power bank for uninterrupted use, or a tripod to support the camera’s 200MP clarity, the right tools enhance everything your phone can do. With the HONOR 400’s intelligent features—from AI photography to dynamic display technology—accessories become more than extras. They become part of a complete mobile ecosystem. For anyone looking to get the most out of their device, starting with the right essentials is the smartest move.
