Owners of Xiaomi smart TVs often face a lack of built-in storage. 8 or 16 GB of built-in memory is quickly becoming insufficient for installing modern heavy apps, games and streaming services. Android TV requires free cache space and proper operation, and a crowded drive leads to a slowdown in the interface and program crashes.
Fortunately, most Mi TVs have USB ports that support OTG technology. This allows you to connect external drives and use them as an extension of internal memory. In this article, we will discuss a technically competent way to solve the problem, which will allow you to install more applications and store media files without having to delete old data.
The expansion process does not require a deep knowledge of programming, but requires careful choice of equipment. Incorrectly selected flash card or erroneous formatting can lead to the fact that the device is not defined by the system. Below are proven methods that will help turn your TV into a full-fledged multimedia center.
⚠️ Attention: Before any manipulation of the file system, we strongly advise you to copy important data from the flash drive to your computer. TV This means full formatting, which will destroy all information on the media.
Choosing the right one USB-expansionary
The first step is to choose the right external drive. Not all flash drives work equally well with the TV operating system. For stable interface and fast application loading, it is recommended to use drives with high read and write speeds. Cheap models with USB 2.0 interface can become a bottleneck, causing slowdowns even when watching high-resolution video.
Memory also plays a role, but it’s important to balance this: Too little (less than 16 GB) won’t work, and too much (over 128 GB) may not be properly defined by older firmware versions. The optimal solution for most users will be 32 to 64 GB models.
Pay attention to the form factor of the device. For TVs that hang close to the wall, the dimensions of the device being connected are critical. Bulky external hard drives can hit the wall or interfere with other cables.
- 🚀 Use the standard drives USB 3.0 (usually blue) for maximum data transfer speed and fast application performance.
- 🔌 Choose flash drives with a compact case or use short ones USB-Extension devices to avoid loading the TV port.
- 💾 Make sure the drive is formatted in the file system FAT32 or exFAT before the initial TV connection.
⚠️ Warning: Some external hard drives require active power if your drive has dual drives. USB-cable or your own power supply, be sure to connect them, otherwise the TV ports may not be enough to start the device.
When buying a new drive, you should give preference to proven brands such as SanDisk, Samsung or Kingston, which ensure the stability of the memory controller, which is especially important for systems running 24/7. Cheap Chinese counterparts can overheat and shut down at the most inopportune time.
Technical requirements and verification of OTG support
Before you start setting up, you need to make sure that your Xiaomi TV model supports memory expansion. Virtually all modern models running Android TV PatchWall, which has built-in support USB-However, the way you integrate may differ depending on the version of the operating system.
There are two main ways to use external memory: as media storage and as extensions for installing applications. The first option works by default, the second requires activation of the memory function or use special utilities. Compatibility check begins with checking the specifications of your model on the official website or in the instructions.
An important aspect is the power consumption of ports. Mi TVs usually give USB currents up to 500 mA or 1 Amp. If you plan to connect energy-intensive devices, make sure they can work in economical mode. Otherwise, the TV may periodically lose communication with the drive.
| Parameter | Minimum requirement | Recommended value | Impact on work |
|---|---|---|---|
| Interface. | USB 2.0 | USB 3.0 / 3.1 | Application loading speed and menu |
| Memory capacity | 8GB | 32-64GB | Number of installed programmes |
| File system | FAT32 | NTFS / exFAT | File support >4GB and stability |
| Reading speed | 10 MB/s | 100 MB/s | No lags when playing 4K |
On older versions (below Android 6.0), Adoptable Storage may not work at all or is unstable, and in such cases, memory expansion is only possible for media files, but not for system applications.
Preparation of the flash drive: formatting and markup
For a Xiaomi TV to use a flash drive as part of the system memory, it needs to be formatted correctly. The standard FAT32 file system has a 4GB file size limit, which can be critical for high-quality movies, so NTFS or exFAT are often required.
You can do the primary formatting directly on your TV. Connect the drive to a USB port (preferably blue if any). The system will automatically detect the new device and prompt you to configure it. Select the option "Use as internal memory" or "Expand storage."
☑️ Preparation of the storage device
If the TV doesn't offer to format the flash drive as internal memory, you can do it through your computer. Use MiniTool Partition Wizard or standard Windows tools. However, remember that once formatted for Android TV, the drive will be encrypted and can't be read on other devices without re-formatting.
The formatting process takes 1 to 5 minutes depending on the volume, during which time the system creates the necessary partitions and file structure.
⚠️ Warning: After formatting the flash drive for the internal memory of the TV, it becomes invisible to the computer. Do not try to force it to read data on the PC - this is impossible without a reset that will remove all installed applications.
Set up Xiaomi TV to work with external storage
After successful formatting, you need to set recording priority. By default, Android TV can continue to store cache and new applications in internal memory, ignoring the connected USB drive. To change this behavior, you need to activate the appropriate settings in the developer menu or system parameters.
Go to the Settings menu → The device → Memory. Here you'll see a list of connected storages. If the flash drive is correctly defined, it will be displayed as "Inner Memory" or «USB-Select it and tick the "Use by default" box».
Some versions of PatchWall require USB debugging mode to be activated. Go to Settings → About TV and press 7 times on “Build Number.” After the message “You became a developer” appears, a new section will appear in the menu.
- 🛠️ In the “Developers” menu, find the “Default Download” option and select yours. USB-accumulator.
- 📂 Make sure that the “Storage” section displays the total volume (internal) + external).
- 🔄 Restart the TV through the switch-off menu → Reset to apply all changes.
