I found app that lets you send push notifications, Skype Notify.
Tried it with a friend, push goes through even if neither of you are logged into skype. Worth a try to save battery.
Sure. But don't you both have to be logged into Skype and have it running?
Kills the battery on my phone...This way, I just open Skype when I need it to make a call.
i log in once and it stays logged in for like a week or so, i don't have to stay in it to receive push notifications, it doesn't use any more battery when you're out of it than that skype notify app, or do you not get how multitasking works on the iPhone?! lol
Do you get how it works? Skype doesn't use push notifications like other apps do. If you check the list of apps that you can allow/deny notifications for, you will notice Skype isn't there. Since Skype is a VoIP app it is an exception to the multitasking rule that other apps follow. Skype does run in the background, and in many people's opinions, it does drain the battery.
It doesn't use the push notification API, it uses the VOIP API which is briefly described here.
I just did a test. I turned off push notifications, then logged into Skype. I exited Skype with the home button, and waited 45 minutes. I called the device and the phone rang. How would it do this if push notifications are turned off? The answer is that some part of Skype is running in the background, and not using push notifications.
The app the OP mentioned sounds like a good solution to the battery problem I get when Skype is logged in and accepting calls.
