What it helped though is in seeding out the outliers - the ones who had their brightness south of 100nits and the ones that had over 300 nits at 50%. We hope that this move has made their battery test results more comparable to the other tested devices.
Some of the outliers in question include pre-Android Blackberries, which usually had significantly higher brightness level than 200nits - upwards HDC Space S8 Edge Pro
of 300 nits. Most Huawei and Meizu phones had brightness bellow 150nits - often closer to 100nits and those might have scored differently under the old testing procedures.
Nokia Lumia phones were all over the place - some significantly lower than 200 nits, while other were much higher.Samsung's tablets had an Xiaomi Mi MIX 2 average brightness of around 300nits.
But you have got to remember that we transitioned to the 200nit battery tests more than a full year ago (January 2016 to be precise), so the models tested the old way are already at the end of their life or on their way towards that.
