Display
Featuring a TFT display, the Energizer E4 has a modest screen size of 1.77 inches, with a resolution of 128 x 160 pixels. The display size and resolution yield a pixel density of roughly 116 ppi, which is sufficient for basic tasks such as calling and texting but not intended for media consumption or detailed image viewing. The limited screen real estate and simple display quality hark back to an era when phones primarily served communication purposes rather than entertainment or productivity.
