Smarter Battery 4.0 analyzes and displays your battery's wear level, discharge cycle, and other important parameters, constantly updating its predictions of how much charge remains and sounding alarms at critical points. Its attractive interface includes a Calibration feature for new batteries, as well as Fast Discharge and Green modes. Smarter Battery 4.0 supports up to four batteries and is free to try with a 10-use, 15-minute limit.
Power plans: The Battery menu accesses and configures power plans.
Gadgets: Optional 2D and 3D gadgets display battery charge continuously on the desktop.
Capacity Evolution: Smarter Battery's Capacity Evolution page displays an easy to understand graph of your battery's life; you can save graphs as JPEGs, too.
Calibration: Continuous smart monitoring of your original battery helps you calibrate replacement batteries to last as long as possible. For best results, keep Smarter Battery running.
Trial limits: The 10-use, 15-minute trial limit might dissuade some users or mask Smarter Battery's virtues. On the other hand, its $14 price is much less than the cost of a new battery.
Smarter Battery 4.0 is among the top battery monitors we've tried. Yes, comparable free tools are available. But Smarter Battery is so affordable (and your laptop's battery so critical) that it really must be compared to freeware battery tools -- a comparison it is likely to win.
Editors' note: This is a review of the trial version of Smarter Battery 4.0.
A battery monitoring utility for portable computers, intended to provide you with all the battery data, to help prolong its life and save its energy. It shows 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. It features a new battery Calibration, Fast Discharge and Green mode functions. This program continuously reads the battery data, making a prediction for the time remaining. Two alarms, for low / critical battery capacity, can be triggered by either values of time remaining or capacity percentage you set. The battery capacity evolution can be graphically displayed for up to 16 hours period of time, so a complete charge or discharge cycle can easily be visualized and analyzed. Both calibration and fast discharge procedures were updated to perform better on Windows 10 laptops or tablets. A battery gadget, with many format options, is displayed by this utility and offers you a fast, clear view to the current battery state. The Power Plan selection is included in its menu, along with Shut down, Standby, Restart, Hibernate commands. A must have, inexpensive, easy to use utility that allows to maximize your battery life and performance.
