The 13.3-inch model will last up to 22.5 hours, with the 14-inch at 21.5 hours and the 15-inch version at 19 hours.
The new models continue to be the most easy-to-carry laptops available on the market today.
LG will show off the Gram at CES 2018, with the laptop going on sale in U.S. in January; more countries are set to get the Gram soon after. The takeaway from this detail is that touchscreens can be thicker than standard screens due to the touch-capable layer, but that is not the case with the panel used in LG's Gram-branded laptops. The body designs have also allowed LG to squeeze the 14-inch model into a body the size of a typical 13-inch laptop, the company says. The 2018 Gram laptops have passed seven US military MIL-STD 810G durability tests for resistance to impact, pressure and temperature.
These aforementioned boosts will be made possible by stronger, more efficient 8th-generation Intel Core i5 and i7 processors as well as larger, 72Wh batteries throughout. The series also comes equipped with DTS Headphone X that provides the multi-channel sound of up to 11.1 channels for 1.5W hi-fi surround sound. The fans have also gotten a bit quieter. The laptops will also feature fingerprint reader and Thunderbolt 3 port as well. LG offer more powerful laptops that deliver greater work efficiency and durability while continuing the products original identity of offering lightest laptop in its category. No word on pricing just yet, but LG is expected to show off the new laptops at CES 2018 next year.
"We're very proud to introduce the new Gram PCs, which have been designed in direct response to those wishing to get an all-around, high-performance laptop with maximum portability", Chang Ik-hwan, head of LG's IT business division, said in a statement.
The models come in 13.3-inch, 14-inch, and 15.6-inch options, weighing in at 2.12 pounds, 2.19 pounds, and 2.41 pounds.
