How to Choose a Smartphone Guide Battery Life

So far, we have talked about the various factors that you have to consider when choosing a Smartphone in the following series of articles:

The last important matter that you have to focus on when buying a Smartphone is Battery Life. The battery is an important piece of hardware because it powers up your device. Without it, you will not be able to utilize its features and enjoy its functionality. So, when choosing a Smartphone, you have to make sure that it has a good battery life.

Batteries Used by Smartphones

Currently, all Smartphones make use of batteries based on Lithium-ion, abbreviated as “Li-Ion” in their technical specifications. You might also notice that the present generation of iPhones make use of Lithium-ion Polymer batteries, abbreviated as “Li-Po” in the technical specifications.

Basically, Li-Ion batteries are cheaper to manufacture as compared to Li-Po. Also, these are capable of storing more energy, have lower self-discharge and do not require priming when first used.

On the other hand, Li-Po batteries are more advanced than mere Li-Ion-based batteries. These come in sleeker encasing than Li-Ion. These feature lesser weight as well, that’s why these are suitable for thin Smartphones. In addition, these have slower aging and more durable compared to the other. However, these are more costly to make and have lesser energy storage capacity than Li-Ion.

Technical Specification

Here are examples of Smartphone technical specifications that mention the type of battery used:

  • Samsung Galaxy S4 – Li-Ion 2600 mAh battery
  • iPhone 5 – Non-removable Li-Po 1440 mAh battery

The values stated in “mAh” stands for the electric charge that the battery has. So, looking at the two examples provided above, you can see that the Galaxy S4 has more electrical charge than the iPhone 5.

Note that it is sometimes indicated whether a battery is removable or not, such as the case of the iPhone 5 technical spec shown above. Also, most of the time, the technical specifications also mention the number of hours that a fully-charged battery can power up the device while idle or in use.

Factors that Decide Battery Life

Be reminded though that the battery technical specification is not the only thing that determines battery life. Here are the elements that can drain your battery faster:

  • Powerful processors
  • Type of screen display (LCD uses more power than LED)
  • High resolution of the display
  • Apps that are being used or running in the background
  • GSM, HSDPA, Wi-Fi and GPS
  • Operating system (Android consumes more power than iOS)

It should be noted that there are many apps that you can use to reduce the consumption of your battery. Moreover, newer GPU’s by Nvidia are now more energy-efficient.
