BatteryBoi is a free, native macOS menu bar app that displays live battery status for your Mac, Apple Watch, AirPods, and other Bluetooth accessories in a single, unified glance.
What is BatteryBoi?
BatteryBoi is a lightweight menu bar utility that replaces macOS's scattered, hard-to-read battery indicators with a clean, always-visible overview of every device in your Apple ecosystem. Instead of hunting through System Settings or relying on the Bluetooth menu to remember whether your AirPods Pro are at 12% or 72%, BatteryBoi surfaces everything at a glance the moment you look up at your menu bar.
The app installs without drama — no elevated permissions, no background daemons hogging RAM — and it slots into the menu bar as a compact, readable percentage badge. Click it and you see a polished popover listing every connected device alongside its charge level. It is the kind of small utility that, once installed, you genuinely stop thinking about because it just works.
What does BatteryBoi do best?
BatteryBoi shines as a unified battery dashboard for households with multiple Apple devices. If you routinely work with a Mac laptop, Magic Keyboard, Magic Mouse, AirPods, and an Apple Watch nearby, keeping mental track of five separate battery levels across three different macOS menus is quietly exhausting. BatteryBoi collapses that cognitive overhead into one popover.
- Unified device overview: Mac, Bluetooth peripherals, and accessories shown together.
- Menu bar at-a-glance: percentage always visible without an extra click.
- Low-battery alerts: configurable warnings before you get caught mid-session with a dead keyboard.
- Minimal footprint: the app is genuinely tiny — it does not try to become a system optimizer or offer twelve features you never asked for.
- Aesthetic polish: the popover feels intentionally designed rather than slapped together, which matters on a menu bar you stare at all day.
I use it specifically because the stock macOS Bluetooth menu lists device names with no charge percentage unless you hover over each one individually. After a week with BatteryBoi I deleted that Bluetooth menu icon entirely — it had become redundant.
Is BatteryBoi free?
Yes — BatteryBoi is free to download and use. The developer distributes it at no cost, and the core functionality (multi-device battery monitoring, menu bar badge, low-battery alerts) is available without any paywall or subscription. There is no freemium tier to navigate and no features held back behind an in-app purchase at the time of this writing.
Who should use BatteryBoi?
BatteryBoi is the right pick for Mac users who own more than one battery-powered device and are tired of getting surprise-drained accessories at the worst possible moment. Power users who keep a full desk setup — wireless keyboard, mouse, AirPods, Apple Watch — will feel the benefit most immediately.
If you use only a MacBook with no Bluetooth accessories, the built-in menu bar battery icon is honestly sufficient. But the moment your accessory count climbs above two, BatteryBoi earns its place. It is also a natural fit for anyone who has already decluttered their menu bar with a tool like Bartender or Ice — one app, one icon, all battery state, zero scrolling.
What are the best BatteryBoi alternatives?
The closest competitors are coconutBattery and Battery Health 3. coconutBattery goes much deeper on MacBook battery diagnostics — charge cycle counts, design capacity vs. actual capacity, temperature history — but it is overkill if you just want to know whether your AirPods will survive the afternoon. Battery Health 3 sits in a similar niche: detailed health reporting with a paid upgrade tier. Neither matches BatteryBoi's clean multi-device at-a-glance simplicity.
AnyToDMG and Apple's native Bluetooth menu round out the free options, but neither was built for this job. If deep battery health analytics matter to you, coconutBattery wins on depth. If you want frictionless awareness without opening a separate window, BatteryBoi is the cleaner daily driver.
How does BatteryBoi compare to coconutBattery?
BatteryBoi wins on simplicity and multi-device coverage; coconutBattery wins on MacBook health depth. coconutBattery tells you whether your battery cells are degrading and whether an Apple Store visit is overdue — it is a diagnostic tool with a menu bar widget as a secondary feature. BatteryBoi treats the menu bar as the primary surface and keeps everything lightweight. For day-to-day peace of mind across your full device fleet, BatteryBoi is the better default. For a laptop health audit before selling a machine or filing a warranty claim, open coconutBattery.
