Watts is a MacBook® battery management and calibration assistant tool.
It's a menu bar app that, apart from the usual battery information (power source used, current battery charge and remaining time), provides advanced data to obtain the maximum performance of your MacBook® battery.

- Your battery needs to be calibrated from time to time to keep the onscreen battery time and percent display accurate, and to keep the battery operating at maximum efficiency. Watts features an intuitive calibration assistant that will guide you through the process of calibrating your battery.

- The calibration scheduling can be adjusted for your needs, and even postponed if you want. Calibration data is automatically logged, so you can see the history of your battery status.

- Watts looks similar to the Mac OS® battery icon menu, and provides some extra options like vertical battery icon and more.

- Watts monitors you battery status constantly and provides you with information and notifications to help you using your MacBook® battery properly. Watts provides detailed information on the battery capacity, charge cycles and health. It also stores your battery data regularly, so you can check its evolution during time.

- Watts provides detailed in-app help, everything is clearly explained!

- Works on any MacBook® model (MacBook®, MacBook Air®, MacBook Pro®)

- Supports Retina® display

- Only for Mac OS® 10.11 "El Capitan" or later

What’s New

Version 2.0.3

Minor version fixing two problems.
The algorithm was not behaving when we were switching on and off the computer in the last steps. Not anymore.
Also when we setting it to sleep and awake in the very last step without plugging it was jumping to the first step. That should not happen anymore.
We hope we will have new things next time!

Cumple su trabajo a la perfección

Si es cierto, que tenían que quitar, en idioma, el Español, si todavía no está.

Muy cara para lo que es

Carisima, lo unico que hace es indicarte los pasos para calibrar la batería, cosa que viene en la web de apple y poner un icono con información y el tiempo que te queda para calibrar la batería de nuevo. Realmente no vale para nada.

Hace poco mas de un mes compré mi primer Macbook Pro y desde el primer día pensé en una aplicación para alargar el máximo posible la vida útil de la batería. Después de probar Watts durante 30 días tengo que decir que estoy encantado con ella. Una muy buena compra.
