Mobile phones have grown incredibly sophisticated, with a growing number performing many of the functions of a full-size computer, as well as some things a desktop computer can’t do, such as navigating with GPS or starting a car. A 2011 Pew Internet Project survey found that 25 percent of smartphone owners do most of their Internet browsing on their phones.
The dilemma is that the more you depend on your phone, the faster you’re going to drain its battery. While screen, processor and storage technology has advanced significantly, lithium-ion batteries haven’t changed much in 15 years. Incremental improvements in battery efficiency have been far outpaced by processing power and screen size and brightness, as well as 3G and 4G radios, Wi-Fi and Bluetooth antennas, HD cameras, GPS and a variety of other hardware, all of which require power.
To conserve battery life on your phone, turn off what you don’t need, optimize what you do and perform a few tasks manually instead of automating them. You can both increase the time between charges and add to your battery’s usable life.
