Smartphone Buyer’s Guide – Battery Life

In a series of articles I clarified most of the factors that you must consider before you buy a Smartphone. When you take a look at most of the Smartphone specification you will find lots of terms that we discussed here and many marketing jargons used in promotions as well. Now you are in good shape to shop for a Smartphone with solid knowledge about them.

Quick Catch-up

Here in the last article in this series I’m trying to focus the attention on Battery life of Smartphone. No matter how advanced they are, once the battery is gone it just become a piece of plastic. So having long lasting battery is very important factor that you must consider.


However, you won’t be able to get a good idea about battery life by just reading technical specification why there are lots of misleading and vague information. Most of the time actual battery life is way lesser than the value in technical specification.

What Decide the Battery Life?

There is no direct answer to this question and of course there are too many factors you have to consider. The worst part here is most of variables are interdependent, hence it’s a very difficult decision to make.

  • Larger the battery, longer the battery life. It will be mentioned in technical specification as mAh.
  • Powerful processors drain battery faster.
  • Large displayed consuming more electricity.
  • LCD display consumes more electricity than LED displays.
  • GSM, HSDPA, Wi-fi and GPS are the biggest battery drainers.
  • Usage style is also a major contributing factor.
  • iOS consume lesser power than Android.
  • Some applications also reduce battery life drastically.
  • There are latest technologies to save battery life such as 4-PLUS-1 technology in Nvidia Tegra 3 Chipset.

These facts might give a good picture about battery life in Smartphone. However there is no way to know the actual battery life till you start using the Smartphone or ask a person who already using one.


The best way to find actual battery life in a Smartphone is ask a likeminded online group, may be in Facebook or a Forum.

Wrapping Up

The built quality of the battery is the major contributing factor for the battery life. The durability of the battery is also important factor. Some smart phones are having great battery life in first few months and then start decreasing rapidly.

According to my experience and social findings Apple iPhone is having one of the most powerful and durable battery. The hardware and software architecture in iPhone is very carefully designed to use the battery power efficiently.

Generally Android devices are having lesser battery power, yet with the latest Nvidia Tegra 3 chipset, they seems showing some improvements.

I’d appreciate if you can share your brand specific personal experience about Smartphone battery life and it will be great support for lots of people.

This is going to be the last article of this series and hope I could sharpen your knowledge about Smartphone and related technical terms and marketing jargons. Our discussion is always open for any further clarification or feedback.
