      while testing video playback, what do you do with the audio? do you turn on the loudspeaker and set the volume level? or just silent it? or do you use earphone for the audio output?

        You should put brightness for example at 150 cd level, not just 50% - this means some devices will give dim screen, some much brighter.

                          Battery life testing at 50% brightness is not the best approach as display technologies handle brightness percentages differently. It would be better if this method is changed from brightness percentage to brightness level (200 cd/m2 or 250 cd/m2. This will make the test more practical.

                            Why are no Lenovo models like the p780, s860, and Z2 Vibe Pro, included in the battery tests? They have 4000mah power and I am sure their battery test results would be interesting to compare with other more popular brands.
