Inaccuracy in measurement is a good possibility, but it could also be the cold. The battery "shrinks" in effect when it is cold, and can't hold as much electricity. If it is charged as much as possible, and later warms up, it "expands" again, and is no longer completely full. You have to keep reminding yourself: that SOC number is not telling you how much electricity the battery is holding. It is just telling you how full it is. Even if the battery was so degraded that it had lost half its capacity, the SOC gauge will still say 100%, or something close to that, when you fill it up.
