Latest known WhatsApp problems on Xiaomi 15 Ultra
1
Why are my WhatsApp notifications delayed or not showing on the Xiaomi 15 Ultra?
HyperOS aggressively restricts background apps to save battery, which silences WhatsApp pushes. Go to Settings > Apps > Manage apps > WhatsApp > Battery saver and set it to No restrictions, then on the same screen turn on Autostart. Also open Settings > Apps > Manage apps > WhatsApp > Notifications (or Settings > Notifications > WhatsApp) and confirm the Messages and Calls channels are enabled with sound and pop-up turned on.

WhatsApp won't share or attach photos from the Xiaomi Gallery on my 15 Ultra, what's wrong?
This usually happens when WhatsApp is denied full media access under Android's scoped permissions. Go to Settings > Apps > Manage apps > WhatsApp > Permissions > Photos and videos and choose Allow all (not Ask every time or Selected only). If sharing from inside Gallery still fails, open Settings > Apps > Manage apps > WhatsApp > Clear data and clear the cache, then retry. See how others solved this on Reddit

The other person can't hear me on WhatsApp voice calls on the Xiaomi 15 Ultra, microphone issue?
First confirm WhatsApp has microphone access under Settings > Apps > Manage apps > WhatsApp > Permissions > Microphone, set to Allow. If the mic works elsewhere but not in calls, the bottom mic may be muffled by a case or a film over the mic port, so clean it and remove any covering. As a test, record a voice memo to verify the hardware mic is clear before assuming it's a WhatsApp bug. See how others solved this on Reddit

How do I transfer my WhatsApp chats from iPhone to the new Xiaomi 15 Ultra?
iPhone-to-Android WhatsApp transfer must be done during the new phone's initial setup using a USB-C to Lightning cable. On a fresh or factory-reset Xiaomi 15 Ultra, install WhatsApp, enter your number, and when prompted choose Move chats from iPhone, then connect the cable and follow the on-screen pairing. You can't migrate the chat history this way once WhatsApp is already set up, so do it before restoring anything else. See how others solved this on Reddit
5
Battery and screen-on time feel poor on the Xiaomi 15 Ultra with WhatsApp running in the background, how can I improve it?
Heavy WhatsApp background sync plus HyperOS wakelocks can drain the battery faster than expected. Reduce media sync in WhatsApp > Settings > Storage and data > Media auto-download (set photos and videos to Wi-Fi only), and lower the screen refresh rate under Settings > Display > Refresh rate if you don't need 120Hz everywhere. Updating to the latest HyperOS build and letting the battery estimate settle over a few charge cycles also helps. See how others solved this on Reddit

How to install WhatsApp on Xiaomi 15 Ultra
1
Choose how to download
On your Xiaomi 15 Ultra you can get the official app two ways: from the Google Play Store — the easiest option, since it keeps WhatsApp updated automatically — or directly from the official website. You can download an APK file, by clicking a link “Download WhatsApp directly”.
2
Open WhatsApp
Launch WhatsApp from your home screen or app drawer and accept the Terms of Service to start setup.
3
Verify your phone number
Enter your phone number. If your Xiaomi 15 Ultra uses dual SIM, pick the line you want WhatsApp tied to, then enter the 6-digit code it sends by SMS — it usually fills in automatically.
4
Restore chats and finish setup
Restore your chat history from Google Drive (use the same Google account), add your name and photo, and tap Allow for notifications so messages and calls arrive reliably.
Stay safe: only ever install WhatsApp from the official Android source. The Download button above already points there — modified copies (GB/Plus/Aero WhatsApp) can get your number banned.
