You plug your POCO F6 into your laptop expecting its storage to pop up, but all that happens is the battery icon starts charging and the computer behaves as if nothing is attached. No drive appears, no folders open, and dragging photos or downloads across feels impossible. The reassuring part is that the POCO F6 has a USB-C port and ships with a USB Type-C cable in the box, so it genuinely supports a wired connection to a PC; the link just needs the correct setting selected on the phone. Work through the fixes below in order, starting with the quickest and safest, and leave the reset for the very end.
Why your POCO F6 charges but never shows up on the computer
On Xiaomi HyperOS, the phone, not the PC, decides what a USB cable is allowed to do, and out of the box it defaults to a charging-only mode. When you connect, the POCO F6 shows a small pop-up offering three choices: [No data transfer], [File transfer/Android Auto] and [Transfer photos]. If you do not actively pick File transfer, the computer only sees a device that is charging and never mounts any storage.
That single default is the number one reason a POCO F6 appears to "not connect," and most owners clear it in under a minute. Because POCO is a Xiaomi brand, the authoritative guidance comes from Xiaomi's official HyperOS support, and it applies to POCO HyperOS phones even though there is no separate POCO-only article for USB-to-PC.
Start with the on-screen USB prompt
Fix 1. Switch the USB mode to File transfer
This is the most common cause, so try it first. With the phone unlocked and connected, the pop-up gives you the mode that decides whether the PC can see files.
- 1.Unlock the POCO F6 so the screen is active.
- 2.Plug it into the PC using a USB-C data cable.
- 3.On the phone, tap the USB pop-up or the USB notification.
- 4.Choose [File transfer/Android Auto] from the options ([No data transfer], [File transfer/Android Auto] and [Transfer photos]).
Once File transfer is selected, the phone's files and folders should become visible on the computer so you can drag content across in either direction.
Fix 2. Re-select the file-transfer prompt each time you reconnect
If files still do not appear, unplug the cable, plug it back in, and make a point of actively choosing the file-transfer option in the pop-up window every time you connect. The official file-transfer guidance is explicit on this, instructing you to "Choose to use USB for File Transfer/Android Auto in the pop-up windows." The prompt can reappear on each new connection, so do not assume the phone remembers your last choice.
Rule out the cable, the port, and the computer
Fix 3. Use a known-good data cable, not a charge-only cable
Plenty of USB-C cables can pass power but cannot carry data, which produces exactly this symptom: the phone charges yet never mounts. Use the original cable that came with the POCO F6 whenever possible. If you are relying on a third-party cable, confirm it is in good condition and actually rated for data transfer, and as a quick test see whether another phone can move files using that same cable.
Fix 4. Try a different USB port and a different computer
A faulty or under-powered USB port on the computer can quietly stop a data connection from forming. Move the cable to a different USB port on the same machine and try again. If it still fails, connect the POCO F6 to a completely different computer; if it works there, the problem lies with the original PC rather than the phone.
Fix 5. Clean and inspect the phone's USB-C port
Lint, dust, or debris packed into the USB-C port can block the pins from making a solid data connection while still allowing a loose charging contact. Look into the charging port on the phone and check that it is clean and undamaged before retrying. Clear out any visible debris gently, then reconnect and watch for the file-transfer pop-up.
Restart both devices and clear software blocks
Fix 6. Restart the phone and PC, and force restart if it is frozen
A temporary glitch on either device can stop the handshake, and a clean restart often resolves it. Restart both the PC and the POCO F6, then reconnect the cable and select File transfer again. If the phone is unresponsive or the screen is frozen, force restart it by pressing and holding the power button for more than 10 seconds, then plug it back in once it boots.
Fix 7. Temporarily disable antivirus or firewall on the PC
Security software on the computer can occasionally prevent the phone from mounting as a storage device. Temporarily disable any antivirus or firewall software on the PC, then connect the POCO F6 and choose File transfer once more. Remember to switch your protection back on as soon as you have finished moving files.
Make File transfer the phone's permanent default
Fix 8. Set the Default USB configuration via Developer options
If you are tired of catching the pop-up every time, you can make File transfer the standing default. This requires enabling Developer options first, then changing one setting.
- 1.Go to Settings > About phone/tablet > Detailed info and specs.
- 2.Tap [OS/MIUI version] multiple times until Developer options are enabled.
- 3.Go to Settings > Additional settings > Developer options.
- 4.Find [Default USB configuration] and change it to [File transfer].
With this set, the POCO F6 connects in file-transfer mode by default, so the PC should recognize it without you needing to tap the pop-up each time.
Update HyperOS to clear a USB detection bug
Fix 9. Install the latest HyperOS update
A software bug can break USB detection, and the fix may already be waiting in a system update. On the phone, go to Settings > About phone > Xiaomi HyperOS > Check for updates and let it search for and install the newest version. Keep the phone sufficiently charged and stay on a stable Wi-Fi connection, and do not interrupt the process while it runs.
When nothing else works, reset and call in Xiaomi
Fix 10. Back up, factory reset, then contact Xiaomi support
Treat this as a genuine last resort, because a factory reset erases all data on the phone, so back up anything important before you start. If the cable will not carry data at all, you can still move your files wirelessly using the built-in Mi Share, or via a cloud backup, before resetting.
- 1.Go to Settings > About phone > Factory reset > Erase all data.
- 2.Select [Back up] (or choose not to), then perform the factory reset.
If the connection still fails after the reset, or the USB-C port looks physically damaged, the issue may be hardware. Submit the problem through Settings > Services & feedback, or take the phone, along with its original cable and charger, to a Xiaomi authorized after-sales or service center for inspection.
Frequently Asked Questions
Does the POCO F6 actually support a wired connection to a PC?
Yes. The POCO F6 has a USB-C port and ships with a USB Type-C cable in the box, both confirmed on Xiaomi's official specs page, so it supports a wired connection. When a PC does not see it, the cause is almost always the phone sitting in a non-data charging mode rather than any missing capability.
Why does my POCO F6 only charge when I plug it into my computer?
By default the phone connects in a charging-only mode, so the PC sees nothing more than a device drawing power. Tap the USB pop-up or notification on the phone and select [File transfer/Android Auto], and the storage will appear on the computer.
Is there an official POCO desktop app I need to install to transfer files?
No separate desktop app is required for basic file transfer. The phone mounts as a standard storage device once you select File transfer on the screen; for a wireless option, Xiaomi's official guidance points to the built-in Mi Share.
How long do I hold the power button to force restart a frozen POCO F6?
Press and hold the power button for more than 10 seconds to force restart, following Xiaomi's official wording. Release once the phone restarts, then reconnect the cable and choose File transfer.
Can I move files off the phone without a cable at all?
Yes. If USB will not cooperate, the built-in Mi Share lets you transfer files wirelessly, and a cloud backup is another route. These are the alternatives named in Xiaomi's official USB-transfer guidance.
