New Bluetooth Runs for a Year Off a Watch Battery

Illustration for article titled New Bluetooth Runs for a Year Off a Watch Battery

There's little stopping Bluetooth from making its way into more devices, but its battery drain is many times that of, say, tried and true IR. But a new, lower power Bluetooth is coming next year.

By Texas Instruments, a new, 6mm-square Bluetooth system-on-a-chip can operate for "more than a year" on a small button-cell battery (like you see in watches or very tiny remotes). Everything from cellphones to laptops could get a battery boost from the technology, but low power, low cost Bluetooth also opens to door to sticking the technology in more places, too (imagine an RF remote or console controller that you don't need to recharge).

It'll be interesting to see how many companies adopt the new tech when it's available next year, along with how many side with the latest developments in Wi-Fi instead. [Texas Instruments and Press Release]

What is it with Bluetooth and battery drain? The Apple BT keyboard uses 3 AAs and those last maybe a couple of months at best. My Logitech RF keyboard goes over a year on to AAs. #newbluetooth
