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.

Release Notes:

- Address macOS High Sierra compatibility issues, including seeing notifications twice if you use Alert style notifications.
- Refine logic around calculations that trigger the "more battery time recommended" message. These should now be less sensitive.

Version 2.0.0
Review by Lkrndu

Does what it says, very well - This app does exactly what it says, especially the part about giving alerts for various battery-related events. This is why we bought it, to help with a discipline of keeping the battery in a sweet-spot range between 40-80% as recommended by some experts to prolong battery life. A little pricey for what it does, but that's ok too, because it DOES do what it says. This review is an "addendum" to my previous one, raising my rating to a full "5".

Version 2.3.2
Review by Caiuszhao

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.

Version 2.3.3
Review by Charlie Lewis

Mostly inaccurate - A Fruitjuice user for some time, it just occurred to me that what the durations of what I had presumed had battery life is not, in fact, the case. My MacBook Pro had been left plugged into the charger at 10PM last night. About 15 minutes ago (2:00PM the next day) I decided to use the laptop, removed it from the charger and powered it on. I then opened FruitJuice’s “Power History” from the menu bar. Instead of seeing the actual time on battery power–––in this case less than a half hour–––the graph depicted 4 hours after charging had completed, giving the misimpression that the laptop had not only been powered on but had been either in use or in sleep mode. I consider this to be misrepresentation.
