So I have this laptop like 5 months ago, and the battery used to last 8-7 hours max doing regular stuff like browsing, but now it last like 3-4 hours max.
The Dell Power Manager says that my battery consume is excelent.
Sometimes it says that I have 5 hours of battery and then 2, and then 4, I don't know why.
It was because I drainend the battery too fast when I played games or could be something else?
 
Solution
I cannot explain it but I like my battery meter to show me % instead of time left. I don't know why that works better for me.

You may want to, say once a month to run on battery and take it down to like 10% before recharging again, to calibrate the batt meter.
