Avast has released the results of its latest study of smartphone battery usage and performance drain by different famous apps. And guess who topped the list again this year. Facebook.

It means Facebook app is the one which takes the largest toll on your phone’s battery and its performance. It drains the highest amount of juice from your phone. And it’s not the first time Facebook is on the top of this list. Facebook has that privilege for some years in a row now. And that’s not all, with Instagram on 6th place, Pages Manager on 9th and Messenger on 10th, the company has four apps on the top 10 now.

Battery draining apps
True Story

According to Gagan Singh, SVP and GM Mobile Business, Avast, “These app performance charts are a great example of helping users understand how they can manage their app usage thoughtfully in order to get the most out of their devices, without limiting enjoyment of their favorite apps.”

Avast puts this quarterly chart by using data anonymously from around 3 million Android phones globally. It emphases on the apps which can be directly installed from Google Play Store.

“Our research helps us identify all of the challenges our customers are facing in using their mobile devices and allows us to provide useful insights and advice (to consumers and developers),” said Singh.

This list has been compiled based upon the apps which launch during the phones’ start up and have the biggest overall impact i.e., data and storage use along with battery drain. The list topped by Facebook has a new entry in second place, musical.ly, a lip syncing app. It could drain a Samsung Galaxy S6 worth of batter (2500mAh) completely in just two hours. What’s more horrifying is that watching 25 clips a day on a 3G or 4G connection could take up to 3GB of data over a month on it. This will comes as a shock to many considering the prices of even 1GB of data.


There are two new entries on the list. One is WhatsCall which touts itself as Skype’s competitor. It has got 4th place on the list. Another debutant is Daily Mail app, which has been placed at the fifth place. I guess this apps need some serious improvements before users find about their power hunger.

The list is not full of just bad news. There’s some good news also. Many popular apps have managed to better their rank on the list. It means they have improved their power requirements and have managed to lower it. Some of them are WhatsApp, SoundCloud, WeChat, ChatOn and BBC iPlayer.

But, the biggest thing to make out from this list is that Facebook is in no mood for improving the battery requirement of their apps, or they have simply failed to do so even if they tried to. Let’s hope they improve themselves in the next list.
