The unknown villain

You may think that the villain of the battery is the screen brightness or even the WiFi, but these are already known resources that consume more battery. What many people don't know is that when there is no carrier signal (2G, 3G or 4G) the battery is extremely consumed.

It's true! The higher the signal, better! Your battery "goes into space" if there is no signal because the phone or tablet needs to work hard to get the signal. A good alternative when there is no signal is put into "Airplane Mode" that turns off 3G, 4G, Bluetooth and WiFi, saving battery power.

Many people use the phone as an alarm clock beside the bed. Check the location where the device is and if the signal is very low or if there is no signal. You should always leave the phone in places with much signal or if you don't need receive calls use the "Airplane Mode" until you're awakened.
