Watts overview

Watts provides MacBook battery management and calibration assistance. It's a menu-bar app which, 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.

Calibration of a battery itself as was in early days promoted is bad for a Li-ion battery. The electronics can be "calibrated" by doing a SMC reset.

Hmh… this can be done in Terminal. Easy. Or do it this way: Let the battery drain, wait at least 5 h, then charge it up to 100 %. This is what Apple says.

Does not work on Mavericks. It worked fine on previous OS X releases. The developer (Binary Tricks) does not respond to my emails. Too bad, I have to look somewhere else.

Over a month ago (as of 23 December 2013) I'd contacted Binary Tricks on an ongoing issue I'd been experiencing. I'm *still* waiting for a reply. Having recently upgraded from Snow Leopard to Mavericks I noticed another quirk in its behavior, the timely reminder to calibrate. It requires 5 hours of uninterrupted rest before plugging the power cord in. It got almost 10 and still sent up the alert that the power plugin had been premature. Looks like I'll be searching for a replacement, especially considering the unresponsiveness of Binary Tricks. A shame.
