[Linphone-developers] iPhone setIdleTimerDisabled and iterate timer

[Mark Krenek]

I've been reviewing the linphone iPhone code to see about using it. I've barely 
scratched the surface but I was wondering about a couple of things that might 
affect battery life.

(1) In startLibLinphone, a timer is set up to fire every 1/10 second. The timer 
calls linphone_core_iterate. I can't tell how expensive all the code in 
linphone_core_iterate is, but I was wondering if there was some other way to 
achieve the desired results without this timer going off all the time. It seems 
to me that a good iPhone app should be event driven and not polling all the 
time.

(2) The PhoneViewController is calling setIdleTimerDisabled which effectively 
keeps the screen from dimming and consequently eats up the battery. Does any 
one know why this is being done?
