And the results are not shocking. Social media apps that keep you connected take the most from your device. So do those that rely on GPS and video, CBS News reported.
Facebook is number one with the highest impact among apps that are run at start-up. Google Maps is number two.
Meanwhile, Snapchat has the highest impact for user-run apps, CBS News reported.
Overall, no matter how the programs start, AVG said that Snapchat, YouTube and Google Maps drain device resources the most.
The year's biggest app, "Pokemon Go," didn't make the list, not because it doesn't impact the phone's usage, but rather because it was released too late to be studied.
Experts said though that it probably would blow the others out of the water on battery usage.
A field tests found that if you didn't stop "catching 'em all," an iPhone 6S Plus would fully drain in 2 hours and 10 minutes. A Samsung Galaxy S6 lasted 2 hours and 40 minutes, CBS News reported.
