Best Mac Battery Apps for MacBook in 2026

The best Mac battery app is the one that does the job you actually have. "Battery app" covers four different jobs: knowing how long the battery will last, checking its health, limiting how far it charges, and monitoring the whole system. No single app does all four well, so here is the best pick for each, what it costs, and what it can't do.

A note on bias: I make TurtleBar, so weigh that pick accordingly. It is listed first because it is the only app here built around runtime. Every other app's features, prices and requirements were checked on its developer's own site on September 26, 2026, and where another app is the better fit, this page says so.

1. TurtleBar: best for time left and saving battery

TurtleBar answers the question the battery percentage can't: how long you have. The menu bar shows a countdown like "3h 42m", the clock time the battery will be empty, time and percentage, or just the percentage, drawn inside a battery icon by default.

The estimate reads the battery's actual power draw in watts and smooths it, so one heavy web page doesn't swing it. When your workload really changes, it catches up within about a minute and says "Adjusting" while it does. It also learns what your Mac draws at each hour of the day, so it gets more accurate over the first few days, and shows a ~ while it isn't confident yet.

The part that saves battery is the automation. TurtleBar can turn Low Power Mode on when the charge drops below a level you pick, when runtime drops below a limit, when your Mac won't reach a target time, after a few idle minutes, or when you open specific apps. It skips the rule while the charge is above 80% (adjustable), turns Low Power Mode back off when you plug in, never undoes a change you made yourself, and every automatic change says why. The popover also shows what Low Power Mode would add ("Adds about 1h 10m", for example) and the five apps using the most power, in watts and in runtime.

• Best for: anyone who works unplugged: students, commuters, people on back-to-back calls.
• Not for: battery health, cycle counts, charge limiting, temperature or Bluetooth device batteries. It doesn't do those; use the apps below.
• Details: $4.99 once, no subscription, 14-day refund. macOS 13 Ventura or later, universal for Apple Silicon and Intel, about 7 MB, signed and notarized by Apple. Battery data never leaves your Mac.

2. coconutBattery: best battery health app for MacBook Pro and Air

If you searched for a battery health app, this is the one to install. coconutBattery shows your battery's current capacity next to its design capacity, the cycle count and other live details, and it can save readings so you can watch wear over months. It reads iPhone and iPad batteries too, over USB in the free version.

The free version covers the Mac and iPhone/iPad diagnostics, saved health readings and a menu bar item. coconutBattery Plus, a one-time purchase, adds Wi-Fi reading of iOS devices, a battery lifetime analyzer with temperature and voltage data, and threshold notifications. It needs macOS 12 Monterey or later.

• Best for: tracking wear over time, or checking a used MacBook before you buy it.
• Not for: today's runtime. It reports on the battery; it doesn't change how your Mac uses power.

3. AlDente: best charge limiter

First, check whether you need it. Since macOS Tahoe 26.4, Apple silicon Macs have a built-in Charge Limit between 80% and 100%: System Settings → Battery, then the info button next to Charging. If a simple cap is all you want, that's free and already there.

AlDente goes further. It stops your MacBook charging at a level you choose, so a Mac that lives on a desk doesn't sit at 100% all day, and it also offers heat protection, sailing mode, calibration mode, a top-up option and Apple Shortcuts support. There is a free version; AlDente Pro is sold as a yearly subscription or a lifetime license, and through Setapp. The developer lists macOS 12 Monterey through macOS 26 Tahoe, on Intel MacBooks from 2013 as well as Apple silicon, so it also covers Macs that can't use Apple's Charge Limit.

• Best for: a MacBook that is plugged in most of the day, when you want more than a simple cap, or an Intel Mac.
• Not for: making today's charge last longer. A limit means less charge when you unplug, which is the opposite of what you want before a flight.

4. iStat Menus: best full system monitor

iStat Menus puts CPU, GPU, memory, disks, network, sensors (temperatures, fans, voltages), weather and battery in your menu bar. Its battery module shows detailed battery state, a menu item that changes when you're draining, charging or full, and the battery levels of AirPods, Magic Mouse, Magic Trackpad and other Bluetooth devices. It's paid, with a 14-day free trial, and needs macOS 11 or later.

• Best for: power users who want every number about their Mac in one place.
• Not for: someone who only cares about the battery. It shows you the data; the decisions stay yours.

5. Stats: best free battery monitor

Stats is a free, open-source (MIT) menu bar monitor for macOS 12 Monterey or later. Its battery module can show the level in the menu bar with the time remaining next to it, and its popup lists health, cycle count, battery temperature, power in watts, the top processes and time to charge or discharge. It can notify you at a low or high battery level. It also monitors CPU, GPU, memory, disks, network, sensors and Bluetooth devices.

• Best for: a free coconutBattery or iStat Menus alternative.
• Not for: automation. The time it shows is the raw estimate macOS itself calculates, the same one Terminal's pmset -g batt prints.

6. Battery Toolkit: archived, so look elsewhere

Battery Toolkit is a free, open-source charge limiter for Apple Silicon Macs only. It can hold the charge between limits you set and cut power from the adapter. Its GitHub repository is now archived and read-only, so it won't get fixes for future macOS versions. If you're looking for a Battery Toolkit alternative, you're on Apple silicon, so the simplest one is free: update to macOS Tahoe 26.4 or later and use the built-in Charge Limit. AlDente is the best-known maintained app if you want more control.

macOS built in: what you already have for free

• Battery percentage: System Settings → Control Center → Battery → Show Percentage.
• Battery Health: System Settings → Battery, then the info button next to Battery Health.
• Cycle count: hold Option, open the Apple menu → System Information → Power.
• Charge Limit: System Settings → Battery, then the info button next to Charging. Apple silicon with macOS Tahoe 26.4 or later, 80% to 100%.
• Low Power Mode: in Battery settings, always on, off, or on whenever you're on battery.
• Which apps use energy: Activity Monitor → Energy tab.
• A time estimate: only in Terminal, with pmset -g batt. Apple removed it from the menu bar in macOS 10.12.2, in December 2016.

If that's all you need, you don't need an app at all. The best free Mac battery apps guide goes further, and why Apple removed battery time remaining explains the gap.

Is there a MacBook battery test app?

"Testing" a MacBook battery means one of two things. A health test is maximum capacity and cycle count: coconutBattery, Stats or macOS's own Battery Health will tell you in seconds, and our battery capacity guide explains what the numbers mean. A runtime test is how long it lasts doing your real work: TurtleBar shows the actual draw in watts, the time left, and five-hour charts of power draw and battery level, so you can see which part of your day costs the most.

Which one should you install?

• You work unplugged and want to know if you'll make it: TurtleBar.
• You want to know how worn your battery is: coconutBattery, or macOS for free.
• Your MacBook stays plugged in at a desk: macOS's Charge Limit on Apple silicon with Tahoe 26.4 or later, or AlDente for more control.
• You want every stat about your Mac: iStat Menus, or Stats for free.
• More than one of the above: combine them. TurtleBar alongside coconutBattery or AlDente works because each does a different job.
