    Verdict

    The Doogee S100 is a rugged smartphone powered by a 6nm MediaTek Helio G99 octa-core processor and runs on Android 12, featuring a generous 20GB of RAM (12GB physical plus up to 8GB virtual RAM) and 256GB of internal UFS 2.2 storage, expandable up to 2TB via microSD. The main pros include its durable construction with IP68/IP69K and MIL-STD-810H ratings for water, dust, and drop resistance, a massive 10,800mAh battery with 66W fast charging and 15W wireless charging support, and a versatile camera system highlighted by a 108MP main sensor and 20MP night vision camera. Cons include its bulky and heavy design, the lack of 5G connectivity (it is a 4G phone), and potentially average graphical performance for high-end gaming compared to some competitors.
