How's your battery life estimations?

[CrippsCorner]

Just been sitting here and noticed how absolutely crap it is!

81% - 1 hr 15 mins
75% - 3 hrs 42 mins
73% - 2 hrs 45 mins
72% - 3 hrs 4 mins

It's all over the place! Anyone else experiencing this?

Yes, the algorithm they use to estimate battery life is very poor. Primarily it seems to need to look at a longer sample set and smooth the data a bit more. It seems to respond almost instantly to whatever the load is at the moment. Idle? 10 hours! Catch it during a CPU spike? 2 hours!

At one point yesterday I had over 14 hours on my estimation

I treat battery life estimations the same way I treat miles-left estimations in my car. I pay absolutely no attention to them because they almost invariably mean diddlysquat.

The same thing applies to a large file download or a copy to another system estimates. You would thing they could come closer to real figures.
