battery issues ??
Authored by: danieleran on Sep 17, '04 01:41:52PM

Bluetooth phones maintain a radio connection as long as they are linked (paired).

My 610, connected via a Dlink USB/BT dongle, seems to lose the link randomly when I connect with the phone in Address Book, but with Salling Clicker, when I publish the menu on the phone, it seems more likely to stay connected, perhaps because Clicker is more aggressive in maintaining a connection.

Even if you aren't transferring files, the phone and the Mac's BT are talking. If BT wasn't in constant communication, it wouldn't know instantly when you leave the area. Actually transferring files probably has little change in how much battery you are using. While BT is designed to use as little power as possible (it uses less power than 802.11b), the tiny battery in small digital phones can't maintain a constant radio link for days on end without recharging.

Having BT switched on makes a minimal difference in battery life; having it on and connected (paired) sucks it dead pretty fast - you can almost watch the battery meter go down!
