"After it got done announcing a small army of inexpensive Windows convertibles and laptops today, Acer turned its focus to smartphones. The company unveiled a brand new Android phablet, the Liquid X2, and it contains one of the largest batteries we've yet seen in a phone. Rated at 4000 mAh, the Liquid X2's battery is larger than the Droid Turbo's. It's bigger than the Note 4's battery, as well. Even when it's powering a 5.5-inch display (Acer hasn't specified the resolution), the enormous capacity of this battery should allow you to skip the charger and keep running through another day or two of use. Lenovo recently announced its own smartphone with a 4000 mAh battery for the Russian market, and we don't yet know whether the Liquid X2 is US bound."
