I switched from an iPhone 15 to this Xiaomi 17 Pro Max. I wasn't really a fan of Android before, but this Hyper OS 3 skin makes it feel just like an iPhone, only much better. I charge my phone every morning (20 minutes), and it charges super fast. I often charge it to about 80%. If I use the phone a lot, it easily lasts 24 hours. Let's say 5/6 hours of screen time on that day. So when you have 100%, you can easily get 1.5 to 2 days out of it. Transferring data didn't go entirely smoothly, but that could be my fault because I didn't know exactly how it worked between Android and Apple, but I tried different apps without success. The screen on the back is a nice addition, but I don't use it very often myself, partly because you don't get notifications on it from WhatsApp, for example. If you receive a call, it will be shown on the back screen. All notifications you receive are easy to set up so that they can be seen on your lock screen, and this works fine. I use the phone in the Netherlands, and all the apps I use work perfectly. Banking apps (ING), Google Wallet links to bank cards and credit cards work excellently, and you can simply make contactless payments in supermarkets or other shops. If you have any doubts about this phone or Chinese ROM, I can highly recommend it....
