To confirm that the sleep is the issue, plug the device into USB and check the developer option to keep the screen on while charging and see if your calls still happen every 20 seconds (if it's still arbitrary, you have some other bug.)
Read up on wake locks and alarms if you need to wake it from that sleep. Note that battery use while awake is close to rate of use for "talk time" (full to empty) and while asleep is close to "standby", so keeping it awake will drain the battery much sooner. * note that the term "sleep" is overloaded and I only use it because there isn't a preferred term for when the processor shuts down when you don't hold a partial wake lock (vs when the screen goes blank but the processor still gets cycles.) My use isn't related to any language sleep function but intended to describe large periods of time where the application processor doesn't get cycles to do things because the OS has shut things down and no wake locks or partial wake locks are being held. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
