This 4.7-inch Android 4.0 handset's 2,520mAh battery claims to have the largest capacity of any sub 5-inch device in Japan, promising more than 18 hours of talk time, and between 580 (3G) and 720 (LTE) hours on standby. If that isn't quite enough power for you, you won't have to wait long for a recharge: Kyocera says the Dingo S can go from 0 to 50 percent in only half an hour.
