Use Your Phone Effectively to Increase Battery Life

Well as the title says, this story is not exactly about 4G/LTE, rather we are going to discuss another aspect of LTE – energy consumption by the devices over LTE networks.

As early 3G takers experienced there are early battery discharges on their mobile phones when they are on 3G. The battery backup of the phones are significantly increased while he is on 2G.

Country’s only LTE operator Airtel is offering two devices – a usb dongle and a wifi router (not the pocket ones). The usb dongle does not need external power, and the WiFi Router is not as mobile as a mobile phone. So in India LTE devices are yet to expose to energy crisis.

There are some reasons behind the heavy power requirement while you are on LTE network. First LTE accounts for several complex algorithm which pack more data in same wavelength, as a result the radio chip uses more power than 2G or 3G/HSPA. Secondly in some LTE phones (for eg from Verizon) have dual antenna for LTE and CDMA1x – to offer voice over 1x via fall back mechanism. Thirdly as LTE network is not as made like a blanket coverage in most of the geographics, while you are off the LTE network, the phone search for the LTE network – which will end up in faster discharge of battery.
