The Pixel 2 charges much more slowly below certain temperatures, but it doesn’t tell you that
Battery advancements haven’t kept in step with performance improvements, but the charging tech for topping those cells up has come a long way. Now, most phones come with some flavor of quick-charging technology that promises to fill our capacious flagships in arbitrarily small periods of time. But in the case of Google’s Pixel 2 XL, it turns out that its “Charging rapidly” notification isn’t always an accurate statement. In low temperatures, Google’s flagship will claim to be charging quickly (10W+) when, in fact, it’s actually charging at less than 4W.
