Smarter Battery is a utility for notebook battery monitoring, intended to provide you with all the battery data, to help prolong its life and save its energy. It can show you the evolution of the battery's capacity during the charge / discharge cycles and computes a few important battery parameters, such as the wear level and discharge cycles count.
This program continuously reads the battery data, making a prediction for the time remaining; it also features two alarms, for low / critical battery capacity, triggered by either values of time remaining or capacity percentage you set.
The Graphic page offers you an easy to understand evolution of the current battery capacity, drawn with a thick orange line, for an interval of 60 (elapsed) minutes. It can be captured, automatically numbered (SBshot1, 2 and so on) and saved as jpg picture in program folder (placed in user's Documents), using the Save data button.
If the battery mode is Discharging, a green line will be displayed, representing the future graphic of the battery power, based on the time remaining read from battery or estimated by the software. For a good battery, most of the time this green line should be parallel with the orange one, without big angle changes (drops of battery capacity).
The battery capacity evolution is not linear, due to the processor usage, hard disk activity, screen brightness and so on. A red line is drawn, with a new estimation of time remaining, based on the highest discharge rate encountered in the current cycle - a kind of worst possible scenario.
