This tiny simple service effectively logs battery and AC use. Lacking an interface, Battery Life Service merely creates a text log of battery and AC use. Installation is simple, but may be unfamiliar for novice users. The app must be installed through a DOS command, and requires a system restart.
Battery Life Service tracks changes in battery life and when the system switches between AC and battery. The log file is easy to read into a spreadsheet app, but the program only lists date, time, battery life time, and battery life percentage. Users have no indication what apps or hardware pulling a load on the battery. Nevertheless, this app could help some users discover battery life trends.
Battery Life Service uses little overhead, and the text file is easy to access. Any user looking to track battery life should give this freeware app a test.
