Frustrated with smartphone batteries that last only half a day?Wolverine XXX Parody LG's new smartphone, the company claims, is a whole-weekend piece of hardware.

The LG X Power2 -- a new product in the company's "specialist" line -- has a monstrous 4,500 mAh battery, which allows for 15 hours of video playback or 18 hours of web surfing, per LG's claims.

The battery is more generous than that of the phone's predecessor, the LG X Power, which had a 4,100 mAh battery, but it's not the largest battery around. Then again, the LG X Power2 is not as fat as some other phones, coming in at 154.7 x 78.1 x 8.4mm. Plus, it apparently takes only two hours to fully charge.

Other than the big battery, the LG X Power2 is an unremarkable, mid-range phone, with a 5.5-inch screen, a 1.5 GHz octa-core processor, a 13-megapixel rear camera, a 5-megapixel selfie cam, 1.5/2 GB of RAM, 16 GB of storage memory, and microSD support.

The LG X Power2 will be available in March and pricing will be announced later.
