This massive capacity represents a significant leap from previous models, promising extended usage between charges. The company revealed this milestone as part of its ongoing teaser campaign ahead of the official launch.

The X300s will also sport a 6.78-inch flat display with 144Hz refresh rate, symmetrical dual speakers, and a custom vibration motor.
