Is your battery not lasting as long as it used to?

In many ways, your laptop battery is like the muscles in your body. Generally speaking, if you exercise regularly, your body responds by staying lean and healthy. Your battery needs exercise, too! If you routinely use your laptop on battery power, your battery responds by maintaining its charge, allowing you to work or play longer.

We’ve Got Your Back

FruitJuice monitors the charge state of your battery and can show you the percentage of usage time you have spent plugged into a power source. Remember: Plugged in and fully charged is the battery equivalent of being a couch potato!

FruitJuice also keeps track of your calibration history, in case you need to someday prove to someone at the Genius Bar that you’ve been treating your battery properly!

Ever wonder how old your battery is? Would you like to know the overall condition of your battery?

Knowledge is Power

FruitJuice to the rescue! We show you all the battery information you need in order to get a complete picture of your battery’s health. Apple’s about notebook batteries page says that your battery should maintain 80% of its original capacity for a certain number of charge cycles. What they don’t tell you is what your current capacity is relative to the factory charge capacity or how many charge cycles your battery should be able to complete!

You’re in the 80% Now

FruitJuice shows you this information and continually tracks the condition of the battery relative to this factory capacity so you’ll always know where you stand relative to this “magic number” of 80%. While we can’t make your battery last forever, we can make sure that you get the lifespan that Apple promises.

Has your laptop ever suddenly shut down even though it said it had 30 minutes remaining?

If so, then FruitJuice can help! The process of calibrating* your battery can cure this discrepancy, allowing you to once again trust the battery estimates shown by your laptop.

You might be asking, “So, how do I calibrate my battery?”

We’re so glad you asked! Apple has a whole article on the long, error-prone procedure! After you read what the procedure involves we think you will agree that, without assistance, battery calibration is difficult to do correctly!

Enjoy a Refreshing Beverage

One of the main features of FruitJuice is that it automates the entire process of battery calibration! In addition, the FruitJuiceApp.com website provides you with automatic notifications (email and SMS) letting you know exactly what you need to do and when. It’s mega awesome! We take care of all the details for you!
