His battery is worthless ... You charge it in the morning and by evening the screen will freeze, the measurements are mediocre and when you have it connected to my phone it often happens that I mean I have ended the call that is coming to my phone and it still rings

The accuracy of its sensors is quite good, but its battery life is extremely low, even without using the Bluetooth connection permanently. If you are interested in the eSIM function, you should consider moving to another smartwatch, as it is not compatible with mobile networks in Greece. In fact, the list of countries and mobile companies mentioned on the official Amazfit website has not changed since its release, and in a related question to the company's support, the answer was that there is currently no forecast for Greece. As for updates, there has been no update for a long time, unlike other models from the same company, and it generally seems like Nexo has been abandoned.

The watch works perfectly after the first update, which included all functions except for voice commands. The only negative aspect I could find is the battery, which lasts approximately 25 hours.

Within 2 days, the battery became faulty. Without having anything open, not even Bluetooth, the battery was dropping rapidly, every minute I looked at it, it would drop by 10%, resulting in it shutting down within a maximum of 3 hours. I sent it back for replacement and the exact same thing happened with the battery within 2 days. At least with 50 euros more, you can get a better brand that actually works!

With all the Firmware updates, battery life lasts for 2 full days of use! You can also make calls with Bluetooth. The initial version of the software doesn't have these capabilities and has some connection issues. Everything disappears in the latest version after the updates! As for its durability, I'm afraid the ceramic frame will break after a fall, so be careful! I would prefer it to have Wear OS, but it's okay. I would also like it to have a more compatible strap so I can choose more easily.

I have the watch for about a week so I have to say on the positive side: Very good construction, screen with very good resolution, many functions, very fast charging about 50 minutes. On the negative side: frequent disconnections (with a Samsung A50 if someone can tell me something that will help with this accepted), battery life lasts one day, does not work as handsfree.
