thank you legnum7 for posting your details. I also use battery plan as "best battery health" most of the times, but it stops charging at 50%, but you said it as 80%,
how to change it?
i am using Lenovo Energy management ver 6.0, i dont find any option to change the stop charge %.

2) 6-cell 48 Whr
3) Battery usage of the course of 1 year:
Scenario 1: Web browsing with average page refresh of 1 seconds, word and excel document and 30% brightness (5 to 7 hours)
Scenario 2: Web browsing while listening to WMP or Youtube music video in the background + around 45 to an hour of full screen flash video, an avg page refresh of 30 seconds and 30% brightness (3.5 to 4.5 hours)
I never played 3d games on the battery as I don't want reduced performance when gaming.

4400 mah battery, z580 i5. About 1 1/2 hours downloading/surfing over wifi + 1/2 - 3/4 brightness setting using the battery conservation mode where the battery charges up to only 60%. Thus, 1 1/2 hours for 60% battery is pretty good - that's about 2 1/2 hours if I started from 100% full charge.
