Just out of curiosity, I wanted to know why does battery indicator is not linearly related with the amount of time i.e. If we see the screenshot which was taken at 4.55 PM , it said battery percentage was 27% or 47 min remaining however, at 5.00 PM the battery percentage was showing 25% but the time increased to 1 hr 3 mins. I don't understand this behavior ? I was not using any program at both instances of time and my system idle process was 99%. Ideally if battery capacity decreased to 25% the time should also been reduced.Why windows behave in this way? or am i running with a poor battery? (which i doubt as i have just got new 6 months back).
OS- windows 7 - 64 bit
Model - Dell inspiron
Thanks very much for answers in advance.
