Apple looking to extend battery life by tinkering with ways to power-off Bluetooth
Apple has filed an application for a patent entitled "Automatic Power-Off of Bluetooth Device from Linked Device". The main idea behind the application is to allow those using Bluetooth to turn off all connected devices by pressing just one button. By making sure that all Bluetooth enabled devices are shutdown when not needed, battery life can be extended. For example, in the application, Apple points out that someone using a Bluetooth headset might forget to turn it off when it is not in use, eating into battery life.

Apple notes that even though some Bluetooth enabled products have timing circuits that turn off the device after a certain amount of time of not being in use, that too also uses the battery even when it is not being used. Apple's idea would allow the user to turn off one Bluetooth device and have the rest follow in-line. Besides turning off power, the linked Bluetooth enabled products could also change the settings of the device it is linked to, like an Apple iPhone.

An Apple iPhone could be preset to automatically turn off all Bluetooth connected devices, or allow minimal Bluetooth activity, when the headphones are turned off. This would allow users to change levels of their Bluetooth communications to "Sniff, Hold or Park" modes. In the "Sniff" mode, a device "sniffs" around for a Bluetooth signal using a reduced amount of power. "Hold" means that a device is connected to Bluetooth but is not being used while "Park" means that the device is connected and is active. Not only can this save battery life on an Bluetooth connected device, but also on the Apple iPhone as well. In the patent application, Apple says that an iPhone could switch to a battery saving mode until a call is received.

Bluetooth 4.0 comes with the new Apple iPhone 4S, set for release on Friday. This version of Bluetooth offers three modes, "Classic Bluetooth," "Bluetooth High Speed" and "Bluetooth Low Energy". The latter offers connectivity up to 160 feet for applications that require low-power, a longer range than the competing RFID has.

why would this not be something worthy of a patent?

I don't actually think he himself believes that Apple shouldn't have been granted a patent, he just saw the words "Apple" and "patent" together and started regurgitating everything thing he reads on the web like "the US patent system has to change"

This is highly specific and it seems like it deserves a patent.

I just am not so sure that a device automatically turning off its bluetooth to whatever extent deserves a patent.

Apps on the android market (and cydia if I'm not mistaken) turn bluetooth, 4G/3G,when the device is inactive or the screen is off or your location and time among other variables , so patterning this does not sound like something worthy

I actually had a cydia app that did that. I unjailbroke my phone for iOS 5 but yeah there is.

Someone told me about software patents like this and why they should not be approved this is basically:

-when a situation "x" is presented turn off bluetooth. They are just using anothey type of situation but the idea is the same.

Its like patterning cutting cake with an army knife, the action of cutting the cake already exist but you are using an army knife or a samuray sword To do it.

Oh and hope you can jailbreak fast =)

Yes lets hope they can get crack this ios 5 thing. : )
I couldnt agree more its an insane thing to patent turning off bluetooth differently. There is no way this goes through zero.

How about patenting the "power button"?

come on .....patents r only for some kind of innovation and not for tinkering with settings

if this trend is established then rom maker would be filing for patents in android world......sounds quite stupid

well i may reconsider this matter if Taco insists......she's really cute (but i will always be a android guy)

apple is applying for a patent by being creative and making the feature that's available on android but better? how id apple getting away with copying the notification feature on the android. it's probably the most widely used feature for me

Its a nice patent but nicer if apple is willing to share it for the right price not hug it all by itself.
