Four years of android user. Just switch to iphone6 2 month ago.

Almost every app requests too many permissions. Almost every app starts a background process to receive notifications. which are very bad.

iOS apps do not (can not) "start a background process to receive notifications".

Notifications are globally handled by the OS over a single dedicated optimized connection. And then dispatched to the individual applications.

And i think Google introduced an API in 5.0 that offers a opt in to something similar.
