FYI, that 'Since' line in GSAM is when it first started collecting statistics. That will either be when you installed it or if you went into the app settings and cleared GSAM's app data. And those values to the left of the date are as much an average of your usage as it is an estimate of how long you'll get out of a charge. If you only use your phone for 30 minutes between charges, it'll say just that.... it isn't an estimate of your phone's absolute battery performance.
