Android users are spending more time on their devices, according to new research from Strategy Analytics. 

Android smartphone users on average spent 138 minutes with their device in May 2014, an increase of 20 percent from the usage in December 2013.

The analysis is based on over one million individual application sessions on more than 1500 Android smartphone users in the United States during the period. 

While Facebook, YouTube and Messaging apps demonstrate category leading performance with over 50 percent share in total time spent in their respective categories, niche segments such as LifeStyle, Productivity, and News, Weather & Sports are characterized by a broad range of smaller apps - no single publisher dominates the category and thereby presents opportunities for new and inspiring app concepts.

Bonny Joy, Chief, Consumer Telemetry Platforms, said in statement that three big categories are social, communication, and browsing, which account for nearly a third of the time spent. 

"Our analysis on the top 25 apps across each of the categories shows games and lifestyle segments are among the most vulnerable in maintaining mindshare as they are quick to come and disappear from our rankings," Joy said.
