https://us.community.samsung.com/t5/Galaxy-S21/S21-Battery-Life-Draining-Quickly/m-p/1700602#M7130 signal strength, screen refresh rate, brightness...all are factors as well....I am getting roughly 6 to 6.5 SOT but I have refress rate maxed, I have the display on WQHD.....again way too many factors...your LG g8 also didn't have 5g which drains battery faster. SOT is not a good battery metric. Fri, 12 Feb 2021 20:39:45 GMT cj5neal 2021-02-12T20:39:45Z
