Energizer Hardcase H501S Battery and Connectivity

Battery and Connectivity

The phone is equipped with a 2500 mAh non-removable Li-Ion battery. While modest in capacity, such a battery is expected for a device focused on ruggedness over extended battery life. The absence of fast charging may require users to plan ahead for full charges. Connectivity features are comprehensive, with 4G LTE capability, Wi-Fi a/b/g/n, Bluetooth 4.0, and GPS/GLONASS. However, the lack of NFC and FM radio might be limiting for some users, and the reliance on a microUSB 2.0 port is somewhat outdated given the prevalence of USB-C in modern devices.
