I am having an odd issue. I have been trying to recalibrate my battery estimate with no success. I have charged it to full, rebooted into recovery and reset the battery stats, let it run dry and then charge it full again, but I am still aving issues.
Just today my battery was indicating 10% charge. I placed it on my charger and in 2 minutes it was up to 60%. An hour later and I am only at 68%.
I've been monitoring it for a few days. Overall charge/discharge rate seems OK. About 15 hours to discharge and about an hour to charge from 10%. I think it is an issue in how the battery is reporting, not that the battery itself is bad.
I would not have complained except for a few close calls where I suddenly drop from 50% to 20% or less.
