The Energizer Hardcase H591S embodies a rugged and durable design that is aimed at providing a robust phone withstanding harsh environments. With dimensions of 164.2 x 79.4 x 12.2 mm (6.46 x 3.13 x 0.48 in), it offers a solid build and significant protection, although it was never released officially. Despite its bulky body, weighing at 260 g (9.17 oz), it promises durability and endurance. The device is designed with a Hybrid Dual SIM (Nano-SIM, dual stand-by) slot, allowing flexibility in usage for the user.
The Hardcase H591S features a 5.99 inch TFT LCD display, maintaining a screen-to-body ratio of approximately 75.9%. With a resolution of 1080 x 1920 pixels and an aspect ratio of 16:9, it offers a dense pixel density of 368 ppi, ensuring clarity and sharpness. Protected by Corning Gorilla Glass 3, this screen is designed to resist scratches and minor impacts, making it apt for rugged usage.
Under the hood, the Hardcase H591S is powered by the Mediatek MT6763 Helio P23 (16 nm) chipset, featuring an octa-core 2.0 GHz Cortex-A53 CPU and Mali-G71 MP2 GPU. This configuration promises smooth performance for everyday tasks and moderate gaming requirements. Running on Android 8.1 (Oreo), the device provides a decent user interface with most necessary features, although an upgrade to newer Android versions is not available.
The smartphone provides 6GB RAM coupled with 64GB of internal storage, ensuring smooth multitasking capabilities and sufficient storage for apps, media, and other data. If more storage is needed, it supports microSDHC cards through a shared SIM slot, offering additional storage flexibility.
The dual main camera setup includes a 16 MP primary sensor with Auto Focus and a 0.3 MP depth sensor. This arrangement is further enhanced by a Dual-LED flash, supporting 1080p video recording at 30fps. The front camera comprises an 8 MP sensor with a supplemental VGA depth sensor, accompanied by an LED flash, ideal for selfies and video calls, albeit without specific video resolution support.
Equipped with a hefty 5800 mAh non-removable Li-Ion battery, the Hardcase H591S guarantees extended usage time. Although the charging solution provided is a basic 10W wired charge, it is sufficient for average recharging requirements, promoting an all-day battery life suitable for an extensive range of activities without frequent recharges.
The device supports GSM / HSPA / LTE networks, compatible with multiple band frequencies. It offers connectivity features like Wi-Fi 802.11 a/b/g/n with Wi-Fi Direct, Bluetooth 4.2 with A2DP and LE, and NFC, increasing its usability for modern connections and transactions. Additionally, it provides GPS for positioning, and the inclusion of a USB Type-C 2.0 with OTG ensures enhanced data transfer capabilities.
Housing a fingerprint sensor rear-mounted along with other sensors such as accelerometer, gyro, proximity, and compass, the phone expands its input and security options. Though announced in February 2019, the device was unfortunately cancelled, and it never made it to the commercial market. Its singular black color gives it a sleek yet rugged appearance.
In conclusion, the Energizer Hardcase H591S was poised to cater to users requiring robustness and durability while offering decent hardware specifications. Although the device is officially cancelled, its design and features reflect an ambitious attempt to fuse ruggedness with functionality, appealing to a niche market of users led by endurance and reliability as primary criteria in selecting a smartphone.
