I asked about this earlier, but haven't seen any clarification yet. When they say "up to three hours more" in low power mode, exactly what does that mean? Three hours left when it says 20% on the battery? Or three more hours than you could normally get without low power mode? I looked up the Apple battery data and the WORST thing it listed for an iphone 6 was 10 hours of internet use (cellular network). I suspect some games may be worse, but they didn't list that. So, assuming the battery drop matches the display percentage correctly (iow, not like how a full take of gas usually drops slowly for the first "half", but much faster for the last "half"), that means 20% power would give you another 2 hours anyway of the most demanding use. So "up to 3 more hours" is an improvement, but really may only be 1 MORE hour than normal. For things that takes less power, the improvement would be even smaller. So, anyone know how to properly interpret that "more" part? Is it going to be an hour or less more than normal or 3 hours more than normal?
