Motorola ES400S (Sprint)
07.06.11
The Motorola ES400S isn't an ordinary cell phone , or even an ordinary business-class phone. Instead, it's what Motorola calls an Enterprise Digital Assistant, designed for business users in vertical markets, as well as for information sharing across multiple devices. It also meets military specification 810G, meaning that it can survive several foot drops onto concrete as well as extreme wind, rain, dust, and other conditions. Regular consumers should stay away from this phone for a multitude of reasons, but the corporate sector may find what it wants here.
Design, Keyboard, and Call Quality
The ES400S isn't small, but given its rugged design, that's to be expected. It measures 5.1 by 2.4 by 0.7 inches (HWD) and weighs 5.5 ounces with the standard 1540mAh battery. An optional, tremendous 3080mAh extended battery adds an extra ounce and another two tenths of an inch in depth. You'll want this, because the ES400S's paltry talk time of just 3 hours and 25 minutes with the standard battery was a real disappointment. The 3-inch PenTile LCD display is a mixture of old and new technologies. It's plastic and resistive, it offers standard VGA (640-by-480-pixel) resolution, and it's designed to be used with the supplied plastic stylus, all of which makes the screen old tech. But it's also LED-backlit and features haptic feedback, which are two unusual features for a stylus-based display. Regardless, it looks unusually bright and colorful for a plastic screen.
