Perhaps unsurprisingly, highly popular and feature-rich apps including Facebook, Netflix, WhatsApp and Google Maps all feature in the list.

The report, which was put together by Avast, also identifies the worst apps for hogging data traffic, eating into storage and draining overall performance.

“For many of us, our smartphones are the main device in our everyday lives. Knowing which of our favourite apps are the hardest-hitting on battery life, data usage, and storage is important so we can manage any that we are regularly using on our phones,” said Gagan Singh, the SVP and GM of mobile business at Avast.

“This quarter’s ‘Most Improved’ accolade is shared between picture messenger tool Snapchat, social media giant Facebook and music streaming behemoth Spotify,” the report says.

“Having previously occupied three of the four top spots for performance-draining apps run by users and on start-up, these companies have made a concerted effort this quarter to improve.”

You can improve your phone’s battery life by deleting some of the apps you don’t need.

With Facebook, for instance, you can get rid of the app and use the social network in your web browser instead. You’ll have to keep hold of Messenger though.

Switching from Google Docs to Microsoft Word could be sensible too.

Some apps, however, can’t be deleted. In this case, Avast recommends limiting notifications from them and reducing background features, refresh intervals and location data usage.
