PS5 and PS4 Controller Battery Level on PC

Read your PlayStation controller's battery level and charging state on a computer, live, without Steam or extra software.

Connect a controller, then press any button

Plug it in with a USB data cable or pair it over Bluetooth. Browsers only reveal a controller after a button press, so press A or ✕ if nothing appears. Nothing is sent anywhere.

The diagram lights up as soon as your controller sends input.

Battery level

Connect a DualSense, DualSense Edge or DualShock 4 directly to read its battery level and charging state. Your browser asks which device to allow, and the permission lasts until you close the tab. This page only reads the controller and sends effect commands (trigger effects, light bar, player lights), never calibration or firmware, and it resets them when you leave.

Decoded from published formats (the Linux hid-playstation driver and SDL); not yet tested on a real controller. Over Bluetooth, deep mode switches the controller to its full report format until it reconnects, and asks first: if another app or game stops seeing it, turn the controller off and on.

Not connected.

Battery

The level the controller reports, in 10% steps, and whether it is charging. It updates live, so plug in a cable to check the charging port.

Motion sensors

Tilt and turn the controller: the model follows it, and the graphs show the gyroscope (turn rate, degrees per second) and the accelerometer (g) on each axis. Put it down flat and run the rest check to measure gyro drift.

Touchpad

Draw on the touchpad with one or two fingers. Each finger gets its own colour and the ID the controller gives it; a dead strip shows up as a gap in the lines. Press the pad to test its click.

No touch yet.

Adaptive triggers (DualSense only)

Pick an effect, then press L2 or R2. Resistance pushes back from the start point; click is a section of resistance that gives way, like a trigger pull; vibration buzzes the trigger from the start point. The bars show where each trigger is.

Report interval

How often the controller sends a report, from the controller's own clock and from the time each report reached this page. This is the report interval, not end-to-end input lag: it leaves out the time a press takes inside the controller, in the game and on the screen.

Press every button once: each one gets a tick when it registers. Values show analog pressure from 0.00 to 1.00.

Health tests

1. Stick drift

Measures where each stick settles when nobody touches it, and checks for buttons or triggers that read as pressed. Pass: under 5% of full travel. Warning: 5–10%. Fail: 10% or more.

Not run yet.

2. Circularity

Rotate each stick slowly around its outer edge. Measures how far the edge strays from a perfect circle. Pass: up to 10% average error. Warning: up to 20%. Fail: above 20% or a direction that can't reach 75% of full travel.

3. Vibration

Plays a rumble. The strong motor is the heavy, low rumble in the left grip; the weak motor is the finer buzz on the right.

Connect a controller to test vibration.

4. Input update rate

Estimates how often the browser receives new data from the controller while you move a stick.

How to check the battery

Connect the controller over Bluetooth or with a USB data cable, click Connect for more tests, and pick it in the list your browser shows. The battery panel shows the level the controller reports and whether it’s on battery, charging or full. It updates with every report, so it changes the moment you plug in or unplug a cable.

Checking the charging port

A worn USB port is a common fault on older controllers, especially the DualShock 4’s micro-USB port. Connect over Bluetooth first, then plug in a cable:

The state should switch to charging within a second or two.
Wiggle the plug gently. If the state flickers between charging and on battery, the port or its small charging board is loose.
If it never shows charging, try a different cable and charger before blaming the port: many cables only carry power one way or are damaged.

Reading the level

Both controllers report the level in about 10% steps. The Linux driver turns the raw value into a percentage the same way this page does: the reported step times 10, plus 5, capped at 100, and 100% when the controller says it’s full. Over Bluetooth, the DualShock 4 adds a cable flag instead of a separate charging state.

The level alone can’t show battery wear. For that, time a full charge down to the low-battery warning. The DualSense Edge has a smaller battery than the standard DualSense, so expect it to run out sooner; see the DualSense Edge tester.

This reading is decoded from published formats (the Linux hid-playstation driver and SDL); not yet tested on a real controller. Over Bluetooth, deep mode switches the controller to its full report format until it reconnects, and it asks before doing so: if another app or game stops seeing the controller afterwards, turn the controller off and on. Deep mode works in Chrome, Edge and Opera on computers. The controller tester covers sticks and buttons with any browser.

Frequently asked questions

How accurate is the battery level?

The controller reports its level in steps of about 10%, so 55% means somewhere around half. It's the same figure a PS5 or PS4 shows, not a precise measurement of the cell.

Can this test battery health?

Not directly: the controller doesn't report the battery's capacity or wear. Charge it to full, note the time, then play until it's low. A DualSense usually lasts several hours; one that drains in an hour or two has a worn battery.

Why does it say charging error?

The controller itself reports a charging fault, for example when the battery is too hot or too cold or the voltage is out of range. Let it rest at room temperature and try another cable and charger.

Does it work over Bluetooth?

Yes. The battery level is in every report over USB and Bluetooth. Over Bluetooth you can watch it drop; over USB you can check that the controller charges.
