It would be nice if battery indicators and such worked as they should, but here is my experience:
My laptop seems ok, the indicator and time left seem to be ok, but I’ve never run the thing completely down, so can’t be sure.
I’ve yet to get a device that does what the spec says, whether it’s playtimg from the clip, run time from my cheap cell phone number of pics from my camera etc. One exception, I had a Canon p&s that did pretty good.
The shiny new car I got last year has a fancy fuel monitoring system that shows tank capacity (like every other car ever made except the early VW bug). It tells me miles to go before I need to refill, average mpg, running mpg etc.
a) The average mpg is consistently 5 mpg higher than I actually measure.
b) The miles to fillup starts flashing at a little under 60 miles to go, gauge shows two bars.
c) If I ignore it and just keep driving, after 20 miles or so the thing goes blank, like FU idiot, now you’re on your own.
d) When I do fill up, I’ve never put more than 10 gallons in what is said to be a 11.5 gallon tank.
- Despite 2 bypass operations, stomach surgery years ago and a couple of other things, I’m now exceeding the average life expectancy figure for an American male. Actually, I was born in England, maybe that explains it. Anywas, I’m not complaining about this liitle factoid.
Moral of al this is like politicians, specs and statistics sometimes lie a little.
