(The developer notes some Mac models group multiple cells into a single cell item Apple never shows more than four cells total regardless of how many are in a laptop.) This section also shows the voltage held across the battery cells, separately chargeable battery components, that make up Apple's overall battery module.

A few more percentage points and I'll take advantage of AppleCare's replacement policy, which calls for swapping out batteries that can't hold at least an 80 percent charge. With my 14-month old M1 MacBook Air, I'm already down to 85 percent of the battery's original capacity. Using Battery Monitor over several years, I can see the quick death of a 2015 12-inch MacBook's battery its replacement and then my current Mac's too-fast capacity decline.

You can see how many times the battery has gone through the equivalent of 100% of its capacity (a full charge cycle) and its expected remaining number of cycles, and compare its current maximum capacity available against what it started with at the factory. Some of this information is found in Apple's System Information app but not as neatly presented. The Battery Health section provides a window into any problems with the components of the battery. To get more information about the adapter connected, click More info and the app reveals what it knows: the name, if available across the connection its negotiated voltage, current (amperage), and power, or the rate at which it charges when actively charging and the kind of adapter it is. The Battery defects label picks up any information Apple registers through self-checks and which are also shown as an alert or status in the system Battery menu. Amperage and Power may be at zero if the computer's battery is fully charged and not currently charging using Apple's algorithm for preventing battery wear. If you have your laptop connected to a power adapter, you'll see the voltage.

The upper-left and upper-right portions provide details about the battery controller (the hardware that manages the battery), including its serial number, and your Mac, noting its manufacture date.Ī Battery Status section breaks down the current state of charging. The overview window has four sections and one very useful button. Raw data about capacity can help demonstrate to Apple what's happening with your battery.
