IPHONE 4S is first phone for low-power Bluetooth.
It has a little-heralded feature that makes it unique among phones, at least for a while: It can talk to a new class of wireless devices, such as watches and heart-rate monitors.
The phone, which went on sale last month, is the first to have a new type of Bluetooth chip that can connect using very little power. The chip uses so little power that it can go into devices that are powered only by a standard "button cell" battery common in watches. The battery can last for years.
Bluetooth Special Interest Group, the industry group behind Bluetooth, this week said these small devices will be labeled "Bluetooth Smart." More fully featured devices such as the iPhone that can communicate with them and with other, standard Bluetooth devices will be labeled "Bluetooth Smart Ready."
Casio of Japan said that late next month it will introduce a watch that's Bluetooth Smart. It will be able to link to a smartphone and alert the wearer to incoming e-mails and text messages by beeping and vibrating.
Sony Ericsson had a watch five years ago that used regular Bluetooth to do the same things the Casio watch will be able to do. But the Sony Ericsson watch weighed nearly half a pound because of its big, rechargeable battery, lasting only three weeks on a charge.
