BatFi 4 for Mac
Mac UtilitiesBatFi, from micropixels, is a battery charge limiter for Apple silicon Macs. macOS has its own optimised charging, but it decides for you. BatFi lets you set a specific limit, such as 80 percent, and hold it for as long as your Mac stays plugged in, which can help slow battery wear on a desk-bound MacBook. The current BatFi 4 line also works alongside the charge limits built into newer macOS versions.
Key Features
- Set and hold a custom charge limit, for example 80 percent
- Charge to 100 percent with one click when you need a full battery
- Change the limit automatically by time and place
- Menu bar app showing charge level, cycles, temperature and health
- One-time licence covering every Mac you own, not a subscription
How to Download
- Check that your Mac has Apple silicon and runs a supported macOS version; BatFi does not work on Intel Macs.
- Download from the official site and run the installer or open the download in the Mac App Store.
- Install BatFi, turn off the macOS charge limit and Optimised Battery Charging as the app instructs, then set your limit.
System Requirements
The developer lists macOS Sonoma 14.8 or later and an Apple silicon Mac for the current BatFi release. Intel Macs are not supported, because BatFi controls charging hardware specific to Apple silicon models.
FAQs
Is BatFi free?
No. It is sold for a one-time payment, and one licence covers every Mac you own. Check the official site for the current price and trial terms.
Why limit charging to 80 percent?
Lithium batteries wear faster when they sit at a full charge for long periods. Holding a lower limit while plugged in at a desk can help the battery keep its capacity for longer.
