4. Bluetooth
Bluetooth can be a blessing. Not only does it allow you to enjoy the generosity of people, it keeps you productive as well. With Bluetooth, you can connect your phone to a Bluetooth enabled headset, share and receive files and so much more. When your Bluetooth isn’t needed, be sure to turn it off. Forgetting to turn if off, like many people do, will drain your battery faster than a bullet train traveling to Tokyo.
