Battery Eater Pro is a small tool to measure the status of the battery installed in your laptop or netbook. On the basis of the simulations performed on the computer, it is possible to estimate the probable operating time of the device without external power supply. This simulation, which is designed to perform a large number of operations using the CPU, graphics and RAM, is nothing more than rendering a simple 3D animation.

It is so well optimized that it is able to subject the portable device to the average load that is generated by many of us in our daily work with a computer. You can start by disconnecting the power cord from the device. The principle of the program is very simple.

During the tests, from time to time, information about the current time and battery status is saved in the log on the hard disk. After the simulation is finished and completely discharged, we can learn how long the laptop has been working on the battery. Battery Eater Pro also offers the function of generating battery charging charts, as well as several test modes (in addition to the above mentioned simulation, which is recommended, among others, the reader mode, simulating only reading text on the device, etc.).

Importantly, in order to get the results as close as possible to the actual results, you need to set up an appropriate power plan and deactivate all applications and system functions that can start working when the computer is not in use.
