X-TREME PQ57: A rugged smartphone that remembers everything
Power and endurance
X-TREME PQ57 demonstrates excellent efficiency that is provided by the 8-core MediaTek Helio P60 processor with a 2 GHz clock speed and an IMG PowerVR graphics accelerator. This combination ensures exceptional functionality and smooth operation. The device comes equipped with 6 GB of RAM and a massive 256 GB of internal storage, perfect for running apps, downloading software, and storing photos and files. With a powerful 20,800 mAh battery — one of the strongest among our smartphones, rivaling standard power banks — you won’t have to worry about running out of charge. Plus, the device supports fast charging, making it even more convenient.
Protection and shock resistance
X-TREME PQ57 is designed to withstand drops and impacts, featuring a sturdy frame produced with the use of the bi-injection molding technique of plastic and rubber. Inside, a titanium damping plate holds all the internal components, slightly adding weight but providing additional impact protection.
X-TREME PQ57 meets IP68 standards, offering maximum protection against water, dust, and dirt ingress. It can operate in extreme temperature conditions, from scorching heat to bitter cold, ranging from -20°C to +55°C.
Thoughtful ergonomics
On the right side of X-TREME PQ57’s frame, you’ll find a power button with an integrated fingerprint scanner and a volume control key. The left side houses a shortcut button and slots for SIM cards and a microSD card. The shortcut button can be configured to perform three different actions: by pressing, pressing and holding, or double pressing, you can quickly open apps and shortcuts like the flashlight.
A USB Type-C port, hidden under a rubber plug at the bottom of the frame, is perfect for charging, connecting headsets, and transferring files to other devices. The back panel features a lanyard loop and a super-bright flashlight, which can be operated using the special Camping Light app. The wide beam is perfect for camping and other outdoor activities.
Modern display and quality cameras
X-TREME PQ57 features a 6.58” Full HD+ IPS display with a resolution of 1080×2408 pixels, delivering sharp images and vibrant colors for a great viewing experience while watching movies, viewing photos, or playing games. The screen is protected by Asahi Glass Dragontrail, resistant to scratches and minor impacts. A protective screen cover is also included in the package.
The device is equipped with a dual camera setup, including a 64 MP main sensor and a 24 MP night vision sensor, which allow you to capture quality photos in various lighting conditions and angles, and record Full HD videos. The 16 MP front camera is ideal for video calls, an essential way to stay connected with loved ones long-distance.
The OTG function for everyday tasks
X-TREME PQ57 supports OTG, enabling you to connect keyboards, mice, storage devices, and even charge other devices when a power bank isn’t available. This feature is handy in the office, at home, or on the go, allowing you to travel light without needing a computer. To use this functionality, simply purchase a special OTG cable.
Thanks to the OTG feature, the smartphone can also share and receive internet through an Ethernet cable. Simply connect an OTG cable and an Ethernet-USB adapter to X-TREME PQ57, and you’ll have a secure wired internet connection that’s much safer than Wi-Fi, making it especially useful for military personnel and volunteers in temporarily occupied areas.
Step into the future with NFC
X-TREME PQ57 allows seamless interactions with various mobile services thanks to NFC. Configure it once, and you can make payments without a card, complete instant mobile transactions, pay for public transport worldwide, and exchange photos and videos with nearby devices without hassle.
Communications and software
Running on Android 13, X-TREME PQ57 offers a clean OS certified by Google Play Protect, ensuring that the phone meets Google’s security standards. It supports 3G and 4G LTE networks and allows memory expansion through a hybrid slot that can hold two nanoSIM cards or one SIM and one microSD card (up to 1 TB). Additionally, it features a flash alert function for incoming calls, WiFi operating on 2.4 and 5 GHz frequencies (IEEE 802.11 a/b/g/n), and a WiFi Hotspot for sharing internet with other devices.
High security standards
X-TREME PQ57 keeps your personal data secure with four unlocking options: password, pattern, fingerprint, and facial recognition.
Navigation and sensors
The built-in GPS module supports GPS, GLONASS, and Galileo, providing precise positioning and navigation for any journey. For enhanced functionality, the device includes light and proximity sensors, a geomagnetic sensor, compass, and gyroscope for improved productivity and entertainment.
