Cooling: a custom military-grade thermal plate plus phase-change thermal sheets (the kind used for gaming-phone cooling) fitted internally — sustained performance without overheating worries. Battery: brand-new upgraded high-capacity battery and a graphene heat-conducting back cover — battery life is maxed out. Everything except the battery and back cover is original. 🖥️ Display Durable panel with always-on support and a near-perfect picture. Faint micro-scratches on the glass — invisible once the included tempered-glass protector is applied. 💼 Everyday software — it's a full desktop OS On Windows, if a normal PC can run it, this can run it: Office: Microsoft Office, WPS Office Communication: WeChat, WeCom, QQ, Tencent Meeting Creative: Photoshop, Meitu XiuXiu and other mainstream apps Stock trading: Eastmoney, Tonghuashun (10jqka), Tongdaxin (TDX), First Capital Securities, Everbright Securities, and more Choose Linux instead and you get a full Linux desktop with its standard software ecosystem — great for developers and tinkerers. 🎮 Gaming Handles most 2D and lightweight titles: Fantasy Westward Journey, Zaomeng Xiyou, Dahua Xiyou, Wendao, Legend of Mir, DNF (Dungeon & Fighter), DDTank, QQ Games, Plants vs. Zombies, Don't Starve Together, galgames, and more. Multi-instance (multi-boxing) verified for Zaomeng Xiyou — ask us to test other games before you order.
