All owners of Android smartphones have tasted the bitterness of the poor battery life of these devices, and have struggled to make them last longer, but even so, they hardly cross the 2 days mark. Although smartphone technology has gotten a long way, having more powerful processors, bigger screens and more memory, the technology of their batteries has stopped at some point.

Battery Life: Prominent Issue of Smartphones


There have not been improvements one a wide scale to make the batteries last longer. Some of use hope that fuel cells will provide the needed solution. It would seem that the manufacturers of the other components have invested in making them more energy efficient, and therefore making devices last longer. Intel has released the new 22nm chip, the Ivy Bridge that is up to 20% more energy efficient than the previous generations, Samsung has released the mighty Galaxy S III with wireless charging capabilities, but even so, these so called “mobile” devices are not truly mobile, having to be recharged daily.

Why smartphones drain the battery so quickly? The question that everyone thinks of has a pretty easy answer: the components that these devices have installed on them, the components that make them smartphones. The screen is in most cases the biggest power drainer of all. Even with Super AMOLED and other such technologies, this component is still the biggest power drainer of all. Also, processors and memory are big power drainers. Wi-Fi is another great example of power drainers that runs your smartphone dry. And yes, your iPhone also needs apps and tips for a better battery life.

Tips to Improve Android’s Battery Life

If you wish to increase the battery life of your Android smartphone, there are a few tricks you can try. However, these will not make your phone last a big period of time, but they will give you a few hours of extra battery life, and in smartphone standards, that is quite a lot.

  • Keep your screen on automatic brightness. Knowing that the screen is the biggest battery consumer, keeping it a bit more dim than at full capacity will give you some extra battery life. Although it won’t look as good, it will make it last longer.
  • Use Data Connection (3G connection) instead of Wi-Fi. Wi-Fi is a big power drain, so keeping it turned off more will give you more battery. It uses a different antenna and so, it will consume more power, unlike the 3G connection that uses the same antenna as the phone’s signal. It’s quite understandable that using one less component will result in less power drain. Also, if you do not use Bluetooth or GPS, it’s better to turn them off. Although they are not big battery consumers and GPS works only when using an app that requires it such as Google Maps, it adds up.
  • Do not use vibrating alerts. The vibrate function on any phone is provided by a tiny motor that turns and vibrates your phone. This motor consumes lots of power and if you can just stick with audio alerts, it will give you some increase in battery longevity.
  • Close background apps. Apps run in background after you close them. This feature allows the phone to quickly load them when you access them again. But these apps running in background consume memory, and therefore power. And this takes us to the main reason for this tutorial. Using task managers and power savers that cut off functions of the smartphone will give you a boost in battery efficiency.
  • Do not use Live Wallpapers. But try using black backgrounds. Because of the way the LED screen works, when a black image is on the screen, the tiny LEDs are turned off, thus conserving power.
