Do I need DS4Windows or Steam to see my DualSense battery?

No. BatteryOnPC reads it on its own, over USB or Bluetooth. If you already use DS4Windows or Steam, you can keep them: the reading is passive.

Why does the DualSense battery move in steps of 10 %?

The controller itself only reports its level in steps of 10 %, on PC as on the PS5. A finer percentage would be an invention.

Can I see the INZONE H9 battery while INZONE Hub is open?

Close INZONE Hub first: the H9 and H9 II share their battery through a channel that only one program can use at a time.

10 models listed: 5 controllers, 1 mouse, 4 headsets

DualSense and DualShock 4

PlayStation controllers are detected as soon as they connect, over USB, Bluetooth or Sony's wireless adaptor for the DualShock 4, with nothing to set up. The reading is passive: BatteryOnPC only listens to what the controller already sends, so it does not get in the way of a game, Steam or DS4Windows.

DualSense and DualSense Edge: the level comes in steps of 10 %, the precision the controller itself reports, on PC as on the PS5.
DualShock 4: steps of about 10 % as well.
Low battery notifications for PlayStation controllers also estimate the remaining play time.

As an option, the DualSense mute button can even mute your PC's microphone: see the DualSense mute button on PC.

INZONE headsets and mouse

INZONE H5 and INZONE Buds: read from their USB dongle.
INZONE H9 and H9 II: read through the serial channel their dongle opens on the PC. Only one program can use it at a time, so close INZONE Hub if the level does not appear.
INZONE Mouse-A: four levels (10, 40, 70 and 100 %).
