Wireless mouse: Bluetooth vs 2.4GHz vs cable

Wireless mouse: Bluetooth vs 2.4 GHz vs wired (practical guide in Portugal)

You want a clean, cable-free desk and a mouse that won't let you down for calls, work, or gaming. Great—but not all "wireless" is created equal.

DECO reminds us of the basics: wireless mice have the disadvantage that you need to change the batteries from time to time.
From there, you choose the right technology.

1) Cable (USB): simplicity and total stability

  • The battery never runs out.

  • Zero pairings

  • Great for gaming and intensive work.

If you want to "buy and forget," the cable is still the best option.

2) 2.4 GHz (USB dongle): consistency and a "fast" feel

In many cases, a 2.4 GHz receiver offers:

  • very consistent connection

  • excellent response feeling

  • Simple installation (plug-and-play)

Warning about interference: There is a well-documented problem: USB 3.0 devices/cables can generate interference in the 2.4 GHz band, causing erratic behavior and lag. Logitech describes this phenomenon and warns that it can result in delayed mouse/keyboard response.
Intel also has a white paper on USB 3.0 interference in 2.4 GHz devices.

How to solve it (in practice):

  • Connect the receiver to a cleaner port (often USB 2.0 helps).

  • Move the receiver away from USB 3.0 drives/USB 3.0 cables (use a USB extension if needed).

3) Bluetooth: perfect for laptops and multiple devices.

Bluetooth shines when:

  • You have a few free USB drives.

  • Do you want to switch between laptop/tablet/PC?

  • You want universal compatibility.

In terms of HID profile design, there is technical documentation stating that HID was designed to allow low-latency connectivity with low power requirements.

When does it make the most sense:

  • mobile work

  • for use at home + outdoors

  • setups with multiple devices

4) Polling rate and wireless battery life

Logitech notes that higher polling rates may consume more battery power in wireless mice.
So, if you want maximum autonomy:

  • You don't need to "force" maximum Hz for office use.

  • Choose balanced mode (especially on Bluetooth).

5) What to choose? (recommendation by profile)

Office / study / laptop

✅ Bluetooth (multi-device) or 2.4 GHz (if you want "zero dropouts")

Gaming (primarily competitive)

✅ wired or 2.4 GHz (with good stability)

  • Keep the receiver away from problematic USB 3.0.

House with many devices (Wi-Fi, hubs, external hard drives)

✅ It could be 2.4 GHz, but position the receiver correctly (or consider a cable connection).

Quick checklist (wireless)

  • Do I need multiple devices? → Bluetooth

  • Do you want a maximum response? → cable/2.4 GHz

  • Do I have USB 3.0 drives connected all the time? → Beware of interference.

  • Want long battery life? → avoid excessive polling rates
