Before I start, sorry if this I posted this in the wrong place, I couldn't find any "Battery" catagories.
My school laptop (Early 2014 macbook air) has recently started running out of battery faster than normal. Beause of this im trying to learn about batteries, so I can get a deeper understanding of the cause of the problem.
I ran a few tests, trying to limit my computers use of hardware,
eg. CPU maxed at 2% usage, low strenght backlights, no network signals.
The average time it took my laptop for a "complete" discharge was around 6.6 hours, and the average dischare rate was around -4.780W.
My battery has a full charge capacity (not designed capacity) of 44.750 Wh.
This is where im getting confused...
Wouldn't it make sense that my laptop at a average discharge rate of -4.780W should last around 9 hours?
What is causing this almost 40% difference ?
Would it come from heat?
Throughout the test the laptop barley went above 35C , so im not sure.
Any and all help is appreciated!
