LG refreshes the 2018 gram laptop of “all day battery”
In January last year, LG refreshed its thin and thin Gram laptop series and boasted that they provided 24 hours of battery life. The problem is that the benchmark LG used to test battery life is 10 years ago (MobileMark 2007), which means that it is not the real representative of laptop use in 2017. However, LG has refurbishing the Gram series, and the requirements for the whole day battery continue.
As The Verge reports, unlike January’s Gram laptops, the battery life claim is much more believable for the 2018 models. LG has updated the 13.3-inch, 14-inch, and 15-inch models to use Intel’s 8th-generation Core i5 and i7 processors. They sip less power, so by default allow for better battery life in the same laptop.
The other key change LG made is the inclusion of a bigger battery. 2017 models used a 60Wh battery, but the 2018 models squeeze in a 72Wh LG BTY-M52 Laptop Battery. More efficient processors and a larger battery equal greatly enhanced battery life you would hope.
Using MobileMark 2014 this time, LG claims the 13.3-inch model achieves 22.5 hours, the 14-inch model 21.5 hours, and the 15-inch model 19 hours on a single charge. While that’s not the same as the 24 hour unrealistic claim made back in January, I think most people would be very happy with 19 hours+ of battery life from their laptop.
We should expect to see the 2018 LG Gram laptops put in an appearance at CES in early January. It won’t be long after that before we get some independent battery testing results appearing.
