The company has added a larger model this time around, so users will have the option of either the standard 5-inch handset or a 5.5-inch alternative.
Both models come with 720p screens, which works out to a 294 pixel-per-inch (ppi) density on the E4, and 267 ppi on the E4 Plus.
Internally, the phones are very similar. You’ll find a 1.3GHz quad-core Mediatek processor powering both handsets.
In terms of RAM, however, the E4 Plus comes with a little more than the standard model – 3GB as opposed to the 2GB on the E4.
But both phones feature 16GB of storage plus the option to expand the internal capacity by adding a MicroSD card.
When it comes to the camera, you’ll find an 8-megapixel rear shooter and 5-megapixel camera on the front of the Moto E4, while the Plus model comes with a 13-megapixel camera on the back, with the same 5-megapixel front-facing offering.
But perhaps the biggest difference between the two handsets comes in the battery department, where Motorola is saying it’s added a massive 5000mAh cell on the Plus model (the E4 features a 2800mAh cell).
