The Bluetooth Special Interest Group on Wednesday has approved the Bluetooth 4.0 low-power wireless networking specification, which focuses on dramatically reducing power consumption, paving the way for tiny wireless sensors
“Some of these new low-energy devices will be able to operate for years on just a tiny, button-sized battery,” said Mike Foley, executive director of the SIG in a blog post.
“The ability to run on such a miniscule amount of power – as little as 10% of the energy used by classic Bluetooth devices – will enable a host of new uses for wireless products in everything from sports and fitness to healthcare and home entertainment,” he said.
Such devices could include wireless heart-rate sensors, pedometers and GPS locators for athletes and health monitoring, as well as home automation tools to control security, lights, appliances and temperature.
The SIG even suggests Bluetooth-enabled watches, which would notify users if they leave their mobile phone behind. The Bluetooth SIG has more than 13,000 member companies worldwide, including Intel, Lenovo, Microsoft, Motorola and Nokia.
Products using the Bluetooth 4.0 spec should be on the market by autumn of 2011, Foley said.
#5. Disable Bluetooth – Knowing that wireless networking can also drain the iPad’s battery, you then can temporarily disable the Bluetooth networking function. This pertains to the connection of accessories as such with the headphones, keyboards and speakers to the iPad. If you would not want to connect these paraphernalia then you can turn the Bluetooth feature off.
Majority of the approaches used to saving battery life of the iPad device are done by temporarily turning off or disabling some of the features that can drain the battery. Other ways to preserve the iPad battery are fulfilled by reducing the brightness of the screen, utilizing auto-brightness and auto-lock feature sooner, disabling equalizer and location services. You can make use of these quick iPad Battery tips to preserve your gadget’s battery life.
7. Avoid using unnecessary features
If you know if might be awhile before you will be able to charge up your phone’s battery, don’t use features or applications that will surely drain its power.
Connecting to the internet, using the camera (especially if your phone is equipped with a flash), updating your Facebook status, sending multi-media messages or listening to music can drain your battery quickly.
Sometimes you don’t know how many apps are running in the background of your smart phone. Using a free app like TasKiller for the Droid, you can turn off all features on your phone saving the battery life.
8. Turn off Bluetooth and Wi-Fi
Bluetooth technology allows you to connect to a wireless headset. Wi-Fi allows you speed up the process of downloading e-mail, applications or music.
Any type of transmission your cell phone does will shorten its battery life.
The Bluetooth feature on your smart phone is constantly on so even if you’re not using your headset it will still drain your battery.
When you’re not using a Wi-Fi hot spot to increase the speed of your phone’s features, turn it off. Just like Bluetooth it, the Wi-Fi technology on your cell phone will continue to look for a Wi-Fi network to connect to.
You will also lessen the chances your private information will be stolen by limiting your use of the wireless Bluetooth or Wi-Fi features.
1. Turn on Auto-Brightness
The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it. Turn this feature on and you’ll save battery because your screen will need to use less power in bright places.
Find it in Settings -> Brightness
2. Use programs with 3D less often.
Not surprisingly, I’ve noticed that when I play games rendering 3D, battery life drops. Using the graphics chips more intensely will crank up power usage, but maybe the drain is also because of the nature of gaming
3. Reduce Screen Brightness
Users can control the default brightness of the screen. Needless to say, the brighter the default setting for the screen, the more battery it requires. Keep the screen dimmer to conserve more of your battery.
Find it in Settings -> Brightness
4. Turn Bluetooth Off
Bluetooth wireless networking is especially useful for cell phone users with wireless headsets or earpieces. But transmitting data wireless takes battery and leaving Bluetooth on to accept incoming data at all times requires even more juice. Turn off Bluetooth except when you’re using it to squeeze more juice from your battery.
Find it in Settings -> General
5. Turn Off 3G
The iPhone 3G and later models operate on two cellular networks, EDGE and the faster 3G. Not surprisingly, using 3G requires more battery life to get the quicker speeds and higher-quality calls. It’s tough to go slower, but if you need more battery, turn off 3G and just use EDGE. Your battery will last longer (though you’ll need it when you’re downloading websites more slowly!).
Find it in Settings -> General -> Network
