The whole issue behind bump charging is not as big of a problem as it is made out to be. The reason the battery drops so quickly without bump charging is the battery charge trickle effect and it is intentional. If you charged your battery to capacity over night and it didn't trickle down then it would be constantly charging even when full. This would cause a shorter life of the battery in the long term. By constantly bump charging your battery you are decreasing the lifetime of your battery as well.
From what I have read, every so often (1 or 2 times a month) you should ruin your battery down to 5-10%, then fully charge it and bump charge it. This seems to recalibrate your battery readings.
