Design and Build

The Energizer Hardcase H621S is designed with durability in mind, reflected in its robust physical dimensions. It measures 163 x 78.2 x 12 mm, with a weight of 241 grams, making it a solid device that feels substantial in hand. The heavyweight build can be attributed to its rugged design and the large battery it houses. The black color variant adds to its aesthetic appeal, providing a sleek yet utilitarian look.

Display

The device sports a 6.2-inch IPS LCD screen with a resolution of 720 x 1520 pixels. This translates to a screen-to-body ratio of approximately 75.3%, with a pixel density of 271 ppi. These specifications ensure that the display provides fairly good viewing angles and color reproduction, though not as sharp as some of the higher-end models. The IPS technology ensures better color accuracy and visibility under direct sunlight.

Performance and Hardware

At the heart of the Energizer Hardcase H621S is the Mediatek MT6762 Helio P22 chipset, built on a 12 nm process. This chipset powers an octa-core CPU clocked at 2.0 GHz Cortex-A53, combined with a PowerVR GE8320 GPU. The hardware configuration is tailored to suit everyday tasks such as web browsing, social media, and light gaming. With 4GB of RAM, the device can handle multitasking reasonably well without significant lag.

Camera Capabilities

The Hardcase H621S is equipped with a single 48 MP rear camera featuring PDAF for faster autofocus. This camera is complemented by a dual-LED flash, allowing for better low-light photography. The rear camera supports video recording at 1080p@30fps, providing decent video quality for personal and social sharing. On the front, the device sports an 8 MP selfie camera, also capable of 1080p video recording, ensuring clear video calls and selfies.

Storage

The device comes with 64GB of internal storage, sufficient for a reasonable amount of apps, photos, and videos. For users who require additional storage, the device supports microSDHC cards. However, it uses a shared SIM slot for expandable storage, meaning you'll have to choose between dual SIM functionality or expanding storage.

Battery Life

A highlight of the Energizer Hardcase H621S is its long-lasting battery life, owing to the Li-Po 5000 mAh non-removable battery. This capacity ensures the device can last through a day of demanding usage without necessitating frequent charging. When it is time to charge, the device supports 15W wired charging, which offers reasonable recharging times.

Connectivity

The H621S is designed to keep you connected with GSM / HSPA / LTE network technology, supporting a variety of 2G, 3G, and 4G bands. The device also features dual-band Wi-Fi (802.11 a/b/g/n/ac), Bluetooth 5.0, NFC, and a USB Type-C port for versatile connectivity options. GPS is available for navigation, and there’s an FM radio for additional entertainment.

Additional Features

This smartphone accommodates useful features such as a fingerprint sensor mounted on the rear for secure and convenient unlocking. Other sensors include an accelerometer and proximity sensor, contributing to an enhanced user experience.

Software

Running on Android 11, the Energizer Hardcase H621S provides users with a clean, intuitive interface that is easy to navigate. Android 11 also brings features like improved privacy settings, smart notifications, and a better overall performance, ensuring users have the latest Android experience.

Price and Availability

Announced and released in June 2021, the Energizer Hardcase H621S is readily available in markets. Priced at approximately 200 EUR, it offers a competitive option for users looking for a durable smartphone that doesn't compromise entirely on modern features.
