Pretty much expected results. Google and Samsung use minimalist AODs, so their battery life is less impacted when it is on, compared to apple’s full screen AODs approach. All of them uses LTPO panels at similar sizes and resolution (probably all made by Samsung anyway). When off, their rankings pretty much revert back to their SoC’s efficiency. Xiaomi for some reason made their pictogram stupidly bright that it drained as much as apple’s.
Also, pretty sure the article’s average and maximum brightness graphs were swapped.
