With a 5000mAh battery, this phone should have no problem lasting three full days between charges with regular use. Blu has even added the choice to charge other devices from the Studio Energy 2's charging port so you can top your friends phones up as long as you use the included adapter.
The navigation buttons are off-screen. They have no backlight, which means that at night they are nearly impossible to find. During the day, they are harder to see than other phones which have a backlight as opposed to blending into the bezel.

Just by looking at the Moto E you can easily tell that it's a budget phone. It still feels sturdy, however it is very chunky at 12.3mm (0.48") thick, and the bezels are large (screen-to-body-ratio is under 65%).
The antenna bands on the side stick out more than they should, and the back panel creaks. The back panel itself is removable, and is made out of plastic that is textured to look and feel a bit like leather. Side bezels are fairly large as well, although the rest of the front looks alright.
The rear panel peels off, allowing access to the removable battery. This means that you can carry an extra battery with you, and replace it and get a full charge instantly. Or, down the road once the battery decays, you can swap it out and get another few years of use out of your phone.
