Not me551ah, but the problem with Android is that: 1. iOS is an Apple operating system. Every iOS device has a daemon running a service that connects with Apple's APNS (Apple Push Notification Service), and that service routes the notifications of every App to the user's device. APNS is non-negotiable, every iOS device has it running, and every App that wants to [reliably] deliver notifications must use it. It's part of the OS, so the OS won't kill it, in fact, if it crashes, the OS restarts it. It also means it's "well behaved", meaning it won't mine cryptocurrencies in the background (unless Apple breaks bad and decides that it's $1T value is not worth it anymore). 2. Android is not a strictly Google operating system. Google has it's APNS analogous, GCM (Google Cloud Messaging), but not every Android device has ties with Google, its open source, meaning millions (billions?) of Android devices out there are running without any Google ties. So in turn, many Apps device to have their own background tasks running all the time, with a persistent connection to the server to watch for notifications. Problem with this it's okay when you have 10 Apps with notifications, not when you have 100 Apps with notifications, each one having it's own background service. Some Android OEM's want their users to have great batt life and kill those background services, leaving notifications dead.
