One thing fundamentally broken on xiaomi phones is GCM. So if you are not whatsapp or Facebook (they have pre configured exceptions) and you need push notifications, you have no options. You can't even have a persistent connection because your app is killed whenever. The user needs to specifically turn off restrictions for your app which do not persist across updates. Users don't really understand all that so your app is "broken" for them.
