I have an Acer Predator Helios 300 9th gen with a GTX1660ti. The battery seems to drain quickly, a couple hours from a full charge seems about right. I was wondering if anyone has done benchmarks on the refresh rate and how that effects the battery life. I have searched the internet but I have only found speculation that it might help to set it to 60hz down from 144hz, but I have not found any metrics with data on how much battery life might be extended by doing this.
