If you have any apps running before connecting your mobile phone to the charger, quickly close it and switch your mobile phone to airplane mode. This will turn off all the wireless radios of your mobile , so that the facility of calling , browsing the web or using GPS on mobile phone will be stopped. The special advantage of this is that your mobile phone will charge faster than usual. During this time, your phone's battery will stop charging in the background. You can get the same benefits by charging with the power off of the phone , but for those who depend on the clock or alarm , turning off the power of the phone completely is not the right solution. Charging in this method does not make much difference than the normal method. But every moment is precious in a hurry. One thing to keep in mind is that the time to charge depends on the size of the battery and the capacity of the charger. Another important thing to keep in mind in case of fast charging is not to see how much is being charged repeatedly. The backlit and display consume a substantial amount of charge. If you see how much is being charged in a hurry, the charge on the display will be lost. Instead, be patient and let the phone charge and unplug the phone before leaving.
