Correct me if I'm wrong, but isn't the point of web sockets a persistent connection to the server, to facilitate sending updates? You assume the battery life hit in using them.
It'd be interesting to see the trade-offs between web sockets and persistent polling.
- CaveTech 13y agoI did extensive research on this about 2 years ago for Android. Holding long standing connections is much more efficient than using multiple HTTP requests, polling included. The reason being mainly the session negotiation and teardown required for making multiple requests, and the fact that the antenna required a higher energy state for creating a new connection compared to keeping an existing connection open.
- thatthatis 13y agoIs it the same result using cellular vs. using wifi?
- CaveTech 13y agoSomewhat, but multiplicative. Wifi requires a good deal more power to begin with, and the high power state of wifi is one of the biggest drains on battery life (after the screen).
