When a software update gets stuck on download on your Xiaomi 15 Ultra, it can feel frustrating, especially when you are waiting for new features or security fixes. The progress bar does not move, the percentage freezes, and nothing seems to happen. In most cases, this problem is caused by network issues, background restrictions, or temporary system glitches, and you can resolve it with a few practical steps.
Why Your Xiaomi 15 Ultra Software Update Is Stuck on Download
- Your internet connection is unstable or switching between Wi-Fi and mobile data.
- Background restrictions are limiting system update services.
- Insufficient storage space is preventing the update from continuing.
- Temporary cache or system glitches are interrupting the download.
- Xiaomi servers may be busy or temporarily unavailable.
Check Your Internet Connection
Software updates require a stable and uninterrupted connection. If your phone keeps switching networks or the signal is weak, the download may freeze.
Open Settings, and then tap Wi-Fi.
Connect to a stable network, and then avoid switching to mobile data during the download.
Restart the Update Download
Sometimes the download process simply gets stuck in the background. Restarting it forces the system to reconnect and resume properly.
Open Settings, and then tap About phone.
Tap MIUI version, and then pause and resume the update download.
Make Sure You Have Enough Storage
If your phone is low on storage, the update may stop downloading without a clear warning. Freeing up space allows the update package to download and unpack correctly.
Open Settings, and then tap Storage.
Delete unused files or apps, and then make sure you have several gigabytes of free space.
Disable Battery and Background Restrictions
Battery optimization can restrict system services, including software updates. Turning these limits off helps the update run without interruptions.
Open Settings, and then tap Battery.
Turn off battery saver, and then make sure background activity is allowed for system update services.
Restart Your Phone
A simple restart clears temporary memory issues and refreshes background processes. This often resolves download freezes caused by minor system bugs.
Open Settings, and then tap Power and restart.
Tap Restart, and then try downloading the update again after the phone boots up.
Try Updating Later
If none of the steps work, the issue may be on Xiaomi’s server side. High traffic during major releases can slow down or pause downloads.
Open Settings, and then tap About phone.
Check for updates again after a few hours, preferably during off-peak times.
Software update issues on the Xiaomi 15 Ultra are usually temporary and easy to fix. Once the connection is stable and restrictions are removed, the download should continue normally and complete without further problems.
FAQs
Why does my Xiaomi 15 Ultra update keep restarting from zero percent?
This usually happens when the internet connection drops or switches networks. Using a stable Wi-Fi connection prevents the download from resetting.
Can I use my phone while the update is downloading?
Yes, but heavy usage or background restrictions can slow or interrupt the download. It is best to keep the phone idle during the update.
What should I do if the update has been stuck for hours?
Restart your phone and try again later. If the issue persists, Xiaomi servers may be busy, and waiting usually resolves the problem.
