MIUI+ 跨屏互联（小米手机与笔记本协作）

中文

MIUI+ 下载与安装前，先确认小米手机符合 MIUI 12.5+ 条件，且设置中提供 MIUI+ 或设备互联。本页介绍手机与笔记本的通知、应用、文字、图片接力和文件互传，并说明跨屏互联连接排查与准备事项。官方页面目前标为 Beta，未列通用安装包、数字版本或逐项更新日志；下载入口仅指向产品说明页。

MIUI+ 是什么：手机和笔记本间的内容接力

小米官方把 MIUI+ 页面标为 Beta，并将它介绍为手机与笔记本协作功能。页面列出通知、应用、文字和图片接力，以及在电脑上浏览、编辑或互传手机文件等使用场景。它依赖两端的系统与应用条件，不能仅凭 Windows 安装包名称判断设备兼容。

MIUI+ 支持条件：核对手机系统与笔记本应用

官方说明要求手机运行 MIUI 12.5 或更高版本，并且在“连接与共享”设置中能找到 MIUI+ 或设备互联选项；笔记本则需已安装 MIUI+。页面没有在本次核验到的说明中列出完整支持机型表或 Windows 最低版本，因此这些未确认项应以对应设备的官方支持信息为准。

MIUI+ 安装与连接步骤：使用当前官方入口

1. 先在手机系统设置中确认 MIUI 版本，并检查“连接与共享”下是否显示 MIUI+ 或设备互联。
2. 确认笔记本已安装 MIUI+。若此前卸载，官网建议通过“小米笔记本电脑助手”重新安装；本次核验的产品页没有提供通用 Windows 安装包直链。
3. 从 MIUI+ 官方说明页查看当前要求，再按设备上显示的官方说明操作。不要把第三方目录标注的 2.5.4.228 当作已核实的当前官方下载版本。
4. 首次连接后先测试一项低敏感内容，再按需启用通知、应用接力或文件互传；部分功能要求手机保持解锁。

MIUI+ 版本与更新记录：Beta 页面未列数字版本

当前核验的小米产品页将 MIUI+ 标记为 Beta，但没有展示可确认的数字版本、发布日期或逐项更新日志。因此本页不把列表旧记录中的 2.5.4.228 当作当前版本，也不将产品页罗列的功能写成某次更新新增内容。若要确认最新状态，请重新查看官方 MIUI+ 页面及设备端官方提示。

常见问题 FAQ：MIUI+ 下载、连接与文件互传

MIUI+ 从哪里下载？ 小米当前产品页是说明入口，不提供可见的通用安装包链接；页面建议卸载后通过小米笔记本电脑助手重新安装。

为什么手机里找不到 MIUI+？ 检查 MIUI 12.5+ 与“连接与共享”设置；具体可用性还取决于设备支持，官方页面没有给出完整机型列表。

手机锁屏后所有功能都能继续吗？ 不能这样假设。官方说明指出通知、最近文件、镜像或便签等部分功能需要手机解锁。

MIUI+ 文件传输速度慢怎么办？ 小米说明传输速度会受周边信号环境影响；先检查两端连接环境，再尝试较小文件。

MIUI+ 与 Xiaomi HyperConnect 是同一产品吗？ 不是。小米将 HyperConnect 作为另一项跨设备服务介绍；它的客户端和支持范围不等于 MIUI+ 的安装包或兼容清单。

MIUI+ download guide: check MIUI 12.5+, phone settings, laptop app, file sharing and connection fixes. The official Beta page lists no installer or changelog.

What MIUI+ does: handoff between a phone and laptop

Xiaomi labels its MIUI+ product page Beta and presents the service as collaboration between a phone and a notebook. The page lists notification, app, text and image handoff, plus browsing, editing and transferring phone files on the computer. Availability depends on both devices and their software conditions; a Windows filename alone cannot establish compatibility.

MIUI+ requirements: check the phone and notebook app

Xiaomi says the phone must run MIUI 12.5 or later and show MIUI+ or device interconnection under Connection & sharing. The notebook must already have MIUI+ installed. The product information reviewed here does not provide a complete supported-model matrix or a minimum Windows version, so check device-specific official support for those details.

MIUI+ installation and setup: use the current official entry

1. Check the phone's MIUI version and look under Connection & sharing for MIUI+ or device interconnection.
2. Confirm that MIUI+ is installed on the notebook. If it was removed, Xiaomi's page points users to Xiaomi Notebook Assistant for reinstallation; the product page reviewed here does not expose a general Windows installer link.
3. Read the official MIUI+ page for current requirements and follow the instructions shown by the devices. Do not treat the ranking archive's 2.5.4.228 filename as a verified current official download.
4. After setup, try a low-sensitivity item first, then enable the features you need. Xiaomi notes that some functions require the phone to remain unlocked.

MIUI+ release and update notes: no numbered build is listed

The Xiaomi product page reviewed labels MIUI+ Beta but does not show a confirmed numbered version, release date or itemized changelog. This guide therefore does not present the third-party archive label 2.5.4.228 as the current version or describe general product features as additions from a particular update. Recheck the official MIUI+ page and device-side notices for current status.

FAQ: MIUI+ download, connection and file sharing

Where can I download MIUI+? Xiaomi's current product page is an information entry and shows no general installer link. It points users to Xiaomi Notebook Assistant for reinstalling after removal.

Why is MIUI+ missing from my phone? Check MIUI 12.5+ and Connection & sharing. Actual availability also depends on device support; the reviewed page has no complete model list.

Do all features work while the phone is locked? No such guarantee is stated. Xiaomi says some notification, recent-file, mirroring or notes features require the phone to be unlocked.

Why is file transfer slow? Xiaomi notes that transfer speed can be affected by surrounding signal conditions. Check the connection environment on both devices and try a smaller file.

Is MIUI+ the same as Xiaomi HyperConnect? No. Xiaomi describes HyperConnect as a separate cross-device service; its client and requirements do not establish MIUI+ download or compatibility details.
