From b1f092f6480e0a9d8d5f99d3363e022952d1af83 Mon Sep 17 00:00:00 2001 From: Nikolaus Voss Date: Wed, 25 Apr 2012 08:59:03 +0200 Subject: sbs-battery.c: Capacity attr = remaining relative capacity Currently, the capacity exported by this driver refers to reg 0x0e, which is the absolute state of charge which according to SBS refers to the design capacity/ energy of the battery. It can be > 100 % and drops below 100 % for a fully charged battery with the battery aging. This is not what the user exspects of a remaining capacity indication between 0 and 100 % with 100 % referring to a fully charged battery. This is provided by SBS reg 0x0d, which is the relative state of charge referring to the full charge capacity.
