As you're going to state here, not everyone agrees on what the "existing terminology" means. You can call it whatever you want as long as everyone using the term understands what the terms mean. Mickey's terms clear up the ambiguity. > > I think what you refer to as 'suspend time' should really be called 'standby > time', since it is how most people think of it - how long will the battery > last when the phone is not being used. That makes assumptions that we can't be sure of yet. We should work to clear up those assumptions first. > > What you call 'usage time' I think we could keep calling 'talk time', since > it seems to me to be the same thing, and is in common use. Broadcasting a GSM signal uses more power than playing Sudoko so the times will be different. I don't think either term here really clears that up. How much talk time does the Freerunner currently get? This means while broadcasting GSM signal. How much usage time can the Freerunner get, for instance playing sudoku? What is the frame in between? Could someone expect 10 hours of "sit on my desk while I sleep and have the phone do nothing"? Does this drop to 6 hours when playing music via a bluetooth headset (since it's processing audio and broadcasting over BT). What battery life could someone expect while making a call from full charge to battery death while using a Bluetooth headset? Perhaps a battery life FAQ might make more sense... I'll see if I can't start one. > > What you call 'standby time' doesn't seem like a very important state to me, > I would think that for most people the phone would either be used (what you > call 'usage time'), or in your pocket or whatever, when you want maximum > battery time, what you call 'suspend time'. There's a critical difference, but exactly how requires more information. The GTA01 currently can't accept incoming calls while in suspend, so for the "average person" suspend is useless since suspending does NOTHING except essentially decrease boot time - it has the same functionality as turning the device off and uses more power. Can the Freerunner resume on incoming call? If so, someone could suspend the device and toss it in their pocket/purse, reap maximum battery life AND keep the primary functionality intact. If it can't resume on incoming call, I'd agree it's essentially useless. > Maybe we could call it 'music > playback time', since that seems to be one usage of this mode. > > /Erland > > > _______________________________________________ > Openmoko community mailing list > community@lists.openmoko.org > http://lists.openmoko.org/mailman/listinfo/community > > _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
