The device can be used to make contactless payments in Switzerland in a similar way to Apple Pay, as it supports NFC and Google Pay should work on it. The Xiaomi 15 Ultra has NFC, which is a prerequisite for mobile payments, and Google Pay is indicated as working on the device. This allows you to make contactless payments with your smartphone in Switzerland, provided your bank supports Google Pay. Apple Pay is limited to iPhones, but Google Pay offers comparable functionality on Android devices.

I have intensively compared the two cameras and their images (on a calibrated large monitor) and I am not a fanboy of any brand (no matter which one). The Xiaomi 15 Ultra definitely delivers better indoor pictures in less favourable lighting conditions compared to the Samsung. BUT: The two styles Leica Authentic and Leica Vibrant are both not designed to give you the most realistic colours possible. For example, my parquet floor is always shown in a completely wrong colour on the Xiaomi (if you only take pictures of landscapes outside, you won't notice this). The Xiaomi also has strong tendencies for overexposure which often leads to "wrong" pictures. You can adjust a lot via filters, but in this mode it has problems with strong light sources such as LED lights, sun, etc. The S25 Ultra is easier to adjust via the filters and you can achieve almost 100% true colour reproduction. But unfortunately there is a lot of noise and sometimes colour distortion indoors in poor lighting conditions. However, if you simply like the Leica style and don't particularly value pictures that are as close to reality as possible, but simply like "beautiful" pictures, you will love the Xiaomi camera. So since both have advantages and disadvantages, it depends on your personal needs.

The smartphone supports VoLTE (Voice over LTE), which allows you to make calls via the 4G network. This enables high-quality voice calls via 4G, which is important for your network operator if 2G/3G calls no longer work.

It is best to report this case to our customer service via the Galaxus Assistant so that it can be checked individually.

The battery has a capacity of 5410 mAh and offers a very long runtime, for example up to 25 hours of video playback. With normal use, the battery usually lasts a whole day, but with intensive use you may need to charge the smartphone once a day. Fast charging is supported with 90W wired HyperCharge and 80W wireless HyperCharge.

No charger included with the smartphone, only a USB C cable supplied

There are some third-party bloatware apps, but they can be completely removed. As far as I know, Chrome cannot be removed from any device (regardless of brand) without root access and neither can most other Google apps. Most (possibly all) MI apps can also be uninstalled, but I would be careful with system-critical apps. Regarding adverts: I haven't seen a single app-integrated advert so far, so I don't think there are any. Hope this was helpful, best regards.

I don't know, sorry.

This version supports multiple languages, including German and English, and comes with a 24-month warranty.

According to our information, third-party camera apps such as Open Camera or Camera FV-5 may have limited access to the full camera hardware. It is common that only one sensor is accessible and often not at maximum resolution, due to API restrictions. Full multi-camera support and advanced features are usually only available via the pre-installed camera app.

According to our information, the product does not include a feature identical to Samsung's Secure Folder. However, it does offer a similar function called "Second Space," which allows the Creation of a separate user environment with its own apps, data, and security settings. This area can be protected with a fingerprint or password.

According to my research, the Xiaomi 15 Ultra does not support desktop mode like Samsung DeX. Xiaomi has not yet built a similar function into its smartphones.
