FruitJuice helps you achieve the longest runtime and lifespan from your Apple notebook battery.

FruitJuice will let you know how long to stay "on battery" each day to keep your battery healthy based on Apple's recommendations. *

FruitJuice keeps a detailed record of your battery charge and discharge activity so that it can make precise recommendations about how long to use your machine on battery based on Apple's recommended usage patterns.

Recommendations are tailored to your specific usage patterns and are adjusted in real-time based on how you actually use your machine.

Flexible configuration allows you to see as much or as little information as you wish.

Notifications will let you know when to plug in or unplug your machine to keep your battery healthy and avoid the surprise of "You are now running on reserve battery power."

FruitJuice also will show you a realistic assessment of the overall condition of your battery: it combines the battery condition, age, factory capacity and lifespan numbers to give you real-time insight into the health of your battery.

The app helps me accomplish what I never made time to do


I have known for a long time that I need to care for the battery in my laptop. And for a long time, I followed an Apple suggested practice of completely running my battery down, letting it sit, uncharged, overnight and then fully charging it the next day. But my reminder to do that came at a time I couldn’t afford to go without my computer so I’d put it off and ultimately forget. Then I was in a situation where I could leave my laptop plugged in almost constantly so I did. But it seems, I killed that battery.

Well, at the time I got a new MacBook Pro, I heard about Fruit Juice on the MacBreak Weekly podast and thought I’d give it a try. It’s super simple to use (provided you can follow on-screen directions). I’ll also mention that I had reason to reach out to the developers and recieved a quick and helpful response!

No use at all


I brought this app and I’d tried it for couple of months. I found this app is far from keeping you bettery healthy. Otherwise, it kills your battery faster than you think. First, this app says: don’t plug your macbook all the time. and it give a length of unplug time as a instruction. Every time I follow this instruction, I found that no matter how faster the power consumption is was, the unplug time is fixed. For example, the suggested unplug time is 1hour and 30 Mins, even if I were play a highly power consumption Game like DiabloIII. After 1.5 hours gaming, my battery will definitely drain out. I don’t really think it will protect my battery, on the contrery, It will only increase my battery cycle time.

Great app - if you have a laptop buy this!


This will tell you when it’s a good idea to plug your laptop in. It keeps track of your battery, so you don’t have to think about it.
Wonderful for not toasting your battery by leaving it plugged in all the time!
