Performance
Under the hood, the Energy JR is powered by a dual-core 1.3 GHz processor, alongside a Mali-400 GPU. Operating on Android 4.4.2 KitKat, the device is clearly rooted in earlier software technology. Aiding this setup is 256 MB of RAM and 512 MB of internal storage, extendable via a microSD card slot. As such, the device is optimally designed for basic functions such as calling, texting, and using lighter applications. However, power users would likely find the performance constraining for more intensive multitasking or gaming.
