Optimizing Battery and Data Consumption in Android

Optimizing Battery and Data Consumption in Android

Battery and network data consumption are two core issues developers have to deal with when developing mobile apps. This is more of a concern in mobile technologies because smartphones have limited resources. There are two key points I will be focusing on this article: battery life and network data reduction. I will go through some tips and examples on how to save battery life and keep network consumption at its minimum.

Optimizing battery life
The hardware components that consume most of the battery are the CPU, sensors, and the screen. Sensors include GPS, NFC, Bluetooth, etc.

Keeping this in mind is simple to determine what are some points for a developer to focus on while developing. Tasks like keeping the CPU utilization to a minimum required, minimizing the radio utilization and minimizing network operations are difficult to apply in many cases but are necessary to build a top of the line app.

In the following sections, I will go through a few factors that have an impact on battery drain. Also, I will mention some tips on how to avoid or reduce battery drain.

Carefully use Animations
It is obvious that animations need a lot of processing power by the CPU and therefore consume a significant amount of power. According to the documentation, most animations look fluid at 30 frames per second. So, going over 30 frames can be a waste of processing power and furthermore, more battery.

Another tip that comes from the documentation is to let the CPU sleep between animations. This is due to the fact that continuous animations lead to constant changes on the device screen. As I mentioned earlier the screen is one of the main factors of battery drain.
