The smartphone Redmi 9T has become a real hit in the budget segment due to its autonomy and reliability, but owners often wonder about the software. Initially, the device entered the market with version Android 10, which was the standard for the end of 2020. Over time, Xiaomi has released major updates, changing not only the version number of the operating system, but also the visual style of the interface MIUI.
To date, software support for this model has gone through several stages of evolution. Understanding what which Android is currently relevant for your device is critical for data security and compatibility with new applications from Google Play. Many users mistakenly believe that the smartphone is “stuck” on one version, although the hidden capabilities of the system can significantly expand the functionality.
In this article we will analyze in detail the path of updates Redmi 9T, consider the transition to a new shell HyperOS and answer the question whether it is worth waiting for further updates. You will learn how to check the current build manually and what nuances are hidden in the process of changing the software version.
Update history and current software version
The path of the software Redmi 9T began with a shell MIUI 12built on the base Android 10. It was a stable but visually overloaded version that received a lot of criticism from the community due to the abundance of advertising and heavy animations. Later, the company released an update to MIUI 12.5 Enhanced Editionwhich optimized background processes and improved privacy.
The next major step was the transition to the core Android 11 with the installation of an interface MIUI 13. This update brings a smoother experience and new widgets specific to the Xiaomi ecosystem. However, the most significant event for the owners was the receipt Android 12 along with the shell MIUI 14, which finally made it possible to remove most system applications without root access.
⚠️ Attention: The process of obtaining major updates may take time. If there is no notification about a new version on your device, do not rush to reset the settings - Xiaomi servers are updated in stages for different regions.
Model owners often wonder whether their gadget supports the latest security standards. Yes, the latest stable builds include security patches that are relevant for the end of the life cycle of this model. It is important to keep an eye on the build number in the menu Settings → About phone, as it determines the presence of critical vulnerability fixes.
The transition to HyperOS: what will change for Redmi 9T
Xiaomi has begun the global introduction of a new operating system HyperOS, which replaces the usual one MIUI. For the model Redmi 9T this transition became possible as part of the update app, although with some restrictions compared to flagship devices. The new system is based on a deep redesign of the kernel Androidwhich should theoretically increase energy efficiency.
Visual changes in HyperOS affect the control panel, notification shade and application minimization animations. Users note that the interface has become more “airy” and the fonts have become more readable. However, it is worth considering that on a budget processor Snapdragon 662 some heavy effects of the new shell may not work as smoothly as on top models.
- 🚀 Memory optimization: An improved algorithm for working with RAM allows you to keep applications in the background longer.
- 🔒 Security: A new data protection system has been introduced and advanced privacy settings for each application.
- 🎨 Customization: New options have appeared to change the style of icons and always-on display (AOD).
Some users are faced with the fact that updating to HyperOS does not arrive immediately. This is due to regional characteristics of software distribution. If you are in a region where the update has not yet been deployed, the system will report that there are no updates available, even if the firmware is already available for other countries.
Before installing HyperOS, be sure to free up at least 5 GB of internal memory. New software requires more space to unpack temporary files than older versions of MIUI.
How to check and install the update manually
Everyone knows the standard way to check for updates: just go to the settings and click the appropriate button. However, there is a hidden method that allows you to check for the latest builds before the official notification. To do this, you need to go to the menu Settings → About phone and quickly click 10 times on the version logo MIUI or HyperOS.
After performing this action, a small icon with three dots will appear in the upper corner of the screen. By clicking on it, you will see the option “Select firmware file” or “Check for updates” with forced polling of the server. This method often helps to “unwind” the system if it is stuck on an old version due to cached data.
☑️ Preparing for a manual update
If the automatic search does not produce results, you can use the method of downloading the firmware manually via_recovery_. You will need to download the official update package (Recovery ROM) from miui.com, rename it to update.zip and place it in the root of the internal memory. Then in the same menu with three dots, select “Select firmware file” and indicate the downloaded archive.
⚠️ Attention: When manually installing the firmware, all data on the device will be saved only if you use the “Update” mode (without clearing data). Select the “Reset” mode only as a last resort, having first saved photos and documents to the cloud.
Comparison of performance on different versions of Android
Many users are afraid to update Redmi 9T to the latest versions Android, believing that this will slow down the device. Indeed, the transition from Android 10 to Android 12 required large resources from the processor. However, optimization in the latest builds MIUI 14 i HyperOS partially leveled this difference.
The table below shows a comparison of key system performance indicators at different stages of the smartphone life cycle. The data is based on average tests of performance and interface response time.
| Software version | Android base | Interface smoothness | Autonomy (screen hours) |
|---|---|---|---|
| MIUI 12 | Android 10 | Average | 9-10 hours |
| MIUI 13 | Android 11 | High | 8-9 hours |
| MIUI 14 | Android 12 | Very high | 8-9 hours |
| HyperOS 1.0 | Android 12 | High | 9-10 hours |
As can be seen from the data, the latest shell HyperOS was able to return the autonomy indicators to the level of the first versions, despite more complex background processes. This was achieved through aggressive management of background tasks and improved processor sleep algorithms.
Why can games slow down after an update?
After a major system update, file indexing and application optimization can take up to 24 hours. During this period, short-term slowdowns are possible even in simple tasks.
Hidden functions and settings of the new system
Updating to the latest version Android opens access to functions that were not available when purchasing a smartphone. For example, in MIUI 14 i HyperOS it became possible to create “Widget Folders”. This allows you to interact with applications directly from the desktop without launching them completely, which saves RAM resources.
Another important feature is advanced clipboard management. The system now automatically recognizes copied phone numbers, addresses and links, suggesting quick actions. In addition, the “Privacy Protection” function has appeared, which masks sensitive data (for example, a phone number in contacts) when providing access to third-party applications.
For those who like to customize the device for themselves, the function of changing the size of the desktop grid and disabling advertising in system applications is available. To remove advertising, you need to go to the settings of each system application (for example, “Explorer” or “Music”) and disable the switch Get recommendations.
The most valuable change in the new versions is the ability to completely remove system software, which previously could not be uninstalled without superuser rights.
Frequent problems after updating and their solutions
Despite careful testing, after installing the new version Android or MIUI users may experience unstable operation. The most common problem is the rapid drainage of the battery in the first days. This is a normal phenomenon associated with the system adapting to the new kernel and re-indexing of files.
Sometimes Bluetooth or Wi-Fi malfunctions. In most cases, this can be resolved by resetting the network settings. To do this, go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth. Please note that after this action you will have to re-enter passwords for saved access points.
⚠️ Attention: If after the update the phone starts to get very hot in standby mode, check the list of running applications. Often the culprit is some third-party application that is not optimized for the new version of Android.
In rare cases, you may need to completely reset the device to factory settings (Hard Reset). This is a radical method that guarantees the cleanliness of the system, but requires first saving all data. It is worth performing it only if other methods of eliminating glitches did not help during a week of use.
FAQ: Frequently asked questions
