Manage susbscriptions after disconnect

I couldn't find a proper documentation about disconnect method.
On my application usually I disconnect the meteor connection to avoid sending messages and save battery, but when I reconnect it I realized that I don't receive updates of a subscription unless I subscribe again.
I have been looking for documentation about disconnect method (on Readme in this repo and in the Java code), but I haven't find what is the exact behavior when disconnecting (with `mMeteor.disconnect()`) and reconnecting again (with `mMeteor.reconnect()`).

I would like to know if there is any way to manage this situation other than tracking which are the subscriptions you use and manage them with an auxiliary Class. Or at least a method to get all active subscriptions.

Thanks
