I noticed a few different times now that it takes my iPad from a full charge of 100% about 45min to an hour of running before the battery life indicator starts to go down. So lets say that after using the iPad for 60 mins, I see that it's at 99% but then it goes down to 98% after using it for a whole less than 60 mins. I guess battery life is not linear and after an initial time at 100% it goes down more rapidly. So the question is - is this how all batteries are supposed to work? or is this some issue with the measurement, where the measurements are imprecise and it's really an approximate measure.
Got a tip for us?

Is iPad battery life usage linear

I think more important as the intervals between the percentages is the overall battery life.
So, if i know for 3 days at 100% then it takes 1/2 a day to hit zero after that, I can go for 3.5 days.
I do know on other Apple Devices they recommend calibration monthly. Google it. It is a process where once a month you run down to 0 and leave off for awhile before charging.
