AirPods, Controller & Bluetooth Device Battery Dashboard

Windows knows how much charge your wireless mouse, keyboard, headphones and controllers have left. It just never tells you until something dies mid-call. fTool Battery Monitor puts every connected accessory on one screen, warns you before any of them runs out, and tells you when a device has finished charging. AirPods are broken out into left, right and case. Everything is read from your own PC and stays there.

Why fTool Battery Monitor

Know Before It Goes Flat

A desk without cables is a desk full of batteries you cannot see. Windows hides the percentages inside Settings, shows one number for a pair of earbuds, and says nothing at all before a device cuts out. Checking six devices by hand is not a habit anyone keeps.

Every Device on One Screen

Mice, keyboards, headphones, earbuds and game controllers appear together with an exact percentage, whether they are connected, charging, or have stopped responding. No opening Settings, no guessing from a three-bar icon.

A Warning You Actually Get

Set the level you want to hear about and a Windows notification arrives when a device drops below it. Another one tells you when charging is finished, so a controller does not sit on the cable all night.

AirPods, Broken Out Properly

Left earbud, right earbud and the charging case each get their own reading, instead of the single combined number Windows shows. You find out which side is about to go quiet before it does.

What You Can Do

Six Devices, One Glance

Cards or a List, Your Choice

The card view gives every device a dial you can read from across the desk. The list view fits far more devices into the same window when you own a lot of them. Both show the percentage, the connection state, the time of the last update, and the Bluetooth signal strength where the device reports it.

Low-Battery Alerts on Your Terms

Pick a threshold anywhere from 5% to 50% and a native Windows notification arrives the moment a device falls below it. The gaming mouse you use for hours can warn at 30% while the keyboard you charge monthly waits until 10%, because any device can carry its own threshold instead of the global one.

And a Nudge When It Is Full

Full-charge alerts fire once, the moment a device finishes charging, so you can unplug it instead of leaving it on the cable overnight. Like the low-battery threshold, it can be turned on for everything at once or for only the devices you care about.

Quiet When You Need Quiet

Set a start and end time and notifications stay silent in between. A mouse that hits 19% at two in the morning does not need to wake you, and a presentation does not need a toast about your headphones.

See How Fast It Really Drains

Open a device and you get its recent activity, charging and discharging with timestamps, alongside a trend of the battery level over time. It is the difference between knowing a controller is at 40% and knowing it will not last the evening. While a device is on the cable and enough progress has been observed, an estimate of the time left until it is full appears too, and stays hidden until there is enough data to stand behind it.

One Click From the Tray

The tray icon opens a compact list of every device without bringing up the main window. Rename devices to whatever you actually call them, hide the ones you do not care about, and put the rest in the order that suits your desk.

Reading the Dashboard

What the Screen Is Telling You

The Colors on a Dial

Green — comfortably charged. Nothing to do about this device today.

Amber — getting low. Worth putting on the charger the next time you stand up.

Blue — charging right now, with a full-charge alert waiting at the end if you asked for one.

Gray — no response. The device is asleep or switched off, so the last known value is shown instead of a fresh one.

What Each Device Shows

Battery level — the exact percentage the device reports, not a three-bar icon.

Status and last update — connected, charging or not responding, with the time the reading came in.

Signal strength — the Bluetooth signal in dBm, for devices that report it.

Left, right and case — earbuds are split into three readings instead of one combined number.

fTool Battery Monitor can only show what your devices are willing to tell Windows. That shapes what it can and cannot do, so please read these points before you buy.

Good to Know

A device has to report its battery level to Windows to appear here. Accessories that keep the figure to themselves cannot be shown by any app, this one included.
Wireless accessories sleep deeply to save power, so a reading can be a few minutes old. Move the mouse, press a key or play some audio and the device wakes and sends a fresh value.
A device that is switched off or out of range is marked as not responding, and its last known value is shown so the card does not simply go blank.
Left, right and case readings depend on what the earbuds report while they are connected. AirPods monitoring has its own switch in Settings.
The app has to be running to watch your devices and raise alerts, so turn on Start with Windows once your thresholds are set.
An internet connection is needed for purchases and may be needed to verify your license. Day-to-day use does not require one.
