DOOGEE Blade 20: 10300mAh Battery Rugged Gaming Phone

The DOOGEE Blade 20 rugged smartphone combines a massive battery with a surprisingly slim design. It features a 10300mAh battery—nearly double its predecessor’s—capable of lasting up to 1415 hours in airplane mode for extended outdoor trips. Despite this large capacity, the phone maintains an ultra-thin 15.8mm body, making it the thinnest rugged phone with this battery size. It supports 18W fast charging for quick power-ups.

The phone runs on Android 15, offering AI-driven interactions, performance optimizations, and advanced privacy tools. It also integrates Gemini AI for text, image, and voice interactions, assisting with tasks like scene recognition and summarization.

For media, it has a 6.6-inch 90Hz HD+ punch-hole display for smooth visuals and a 16MP main camera with an 8MP front lens. The camera includes AI scene recognition and Google-powered features for object search, homework help, text extraction, and translation.

Performance is handled by a T7200 octa-core processor, 20GB of RAM (4GB physical + 16GB virtual), and 128GB of internal storage, expandable via TF card up to 2TB.

Built for durability, it meets IP68/IP69K and MIL-STD-810H standards for resistance to dust, water, and harsh conditions. Additional features include NFC for payments, fingerprint/face unlock, side smart keys, and multi-system GPS support.

It is a dual-SIM 4G unlocked phone with a triple card slot (2 nano-SIM + 1 TF card). Supported bands include 4G TDD: B34/38/39/40/41; FDD: 1/2/3/4/5/7/8/18/19/20/25/26/28AB/66; 3G WCDMA: B1/2/4/5/8; 2G GSM: B2/3/5/8. Please verify band compatibility with your local carrier before purchase.
