Xiaomi launched its high-end smartphone, Mi 11 in China on December 28, 2020. It features a 6.81-inch E4 AMOLED quad curved DotDisplay with120Hz refresh rate, equips 108MP primary camera, packs a 4,600 mAh battery with 55W, features, and more.
MIUI 12.5 update comes with a bundle of new features including new system animation design, new light Cone dynamic effect architecture, System sound design, hundreds of global biological sounds, new snow mountain super wallpaper, and more. It also supports Android gesture Turbo which provides extremely fast response in the system and upgraded its computing power.
The progress bar of the Xiaomi Mi 11 system update can be completed directly on the boot interface. After the progress bar is completed, it can be used directly in the new system, avoiding prolonged off-state loading.
Xiaomi Mi 11 uses an Android virtual A/B partitioning mechanism to achieve a seamless update effect, improve update stability, and avoid problems like phone blockage due to abnormality in the OTA update process.
Android works on the two update mechanisms that are A/B (seamless) update and non-A/B update. To reduce code complexity and improve update ability, Android 11 added these two mechanisms. The new update mechanism combines the advantages of the two predecessors by seamlessly updating all devices without reducing virtual A/B storage costs.
- Virtual A/B update is as seamless as A/B update. Virtual A/B updates can reduce the time that the device is offline and unavailable.
- Virtual A/B updates can be reverted. If the new operating system fails to start, the device will automatically revert to the previous version.
- The virtual A/B update only uses minimal additional space by copying partitions used by the bootloader. Other updatable partitions are snapshots.
After installing the update, the device will update the files in partition B while keeping the phone in partition A. You can update the inactive partition B in the next version of Android until the user restarts and the device switches from slot A to partition B, remaining on the updated version of Android.
This makes the update process almost entirely in the background. If your phone is updated frequently, then this feature is called seamless update which can save a lot of time.
The seamless update is a big victory for Android users but at the cost of storage capacity. However, this storage space strategy has not yet been accepted by some companies. Taking Samsung as an example, it will occupy up to 3GB of additional storage space on the device.
As Android 11 devices adopt mandatory A/B partitions, seamless updates may also be more common. This can help Android users to update their devices more often as it will take less time.
