Is your phone or tablet battery constantly reduced to a sliver of red on the screen? New research has found the worst performance-draining apps on Android devices, and Facebook is the biggest culprit.
The findings come from new research conducted by AVG which took anonymous data from more than 1 million AVG Android app users in order to collate a list of the worst offenders in the Android app world (measured over Q3 2014, based on apps with more than 1 million Google Play downloads).

Culprits included pre-installed apps pushed out by device manufacturers, with 3 of the 10 biggest battery draining apps that run on start-up coming from Samsung. News apps also warrant a mention, particularly those that update in real-time, with the New York Times' Breaking News app topping the list of the most storage-hungry apps we use.
