The X Power promises monster battery life.

Two days of battery life. That's how long LG says its X Power phone, which it officially announced earlier this summer, is expected to last between charges.

You might think that such a giant 4,100mAh battery would top a list of other high-end hardware, but LG takes the opposite approach, surrounding the (nonremovable) battery with midrange specs that help pin the full retail price to $130.

Already available for US Cellular and Cricket Wireless, Sprint and Boost Mobile's version contains one important difference: it uses MediaTek's Helio P10 chip (1.8GHz octa-core) rather than the quad-core Qualcomm processor found in other models.

While we haven't yet been able to compare this with the Qualcomm variation, that'll be one of the first things we do when we get our hands on both phones.

Curious about the other important specs? The LG X Power also has:

  • 5.3-inch screen with a 1,280x720-pixel resolution
  • 8-megapixel rear camera
  • 5-megapixel front-facing camera
  • Android 6.0 Marshmallow software
  • microSD card slot

The LG X Power goes on sale today at prepaid carrier Boost Mobile, and arrives at Sprint next week.
