The annual Avast Android App Report tells you which apps are eating up your phone’s storage and your mobile data allocation in no time.
Chances are that 99% of you reading this are getting a variation of these two messages frequently — or both if you’re unlucky:
Mobile data: Most phone providers limit your contract to a certain amount of mobile data volume, such as 2, 4, or 10 GB. While some also advertise so called “UNLIMITED” plans, most of them aren’t really unlimited and you’ll hit a wall when you exceed their “Fair Use Policy.” (For example, recently, I’ve been throttled by two major providers in the US and Japan once I exceeded 5 GB/day, which, if you’re working with big files, is easy.) There are apps out there that transfer huge amounts of data back and forth. Sometimes you know what’s causing the data, like when I binge-watched the entire season of Handmaid’s Tail in less than a day. In other cases, some apps just download and upload data without you knowing. In both cases, it’s easy to hit your limit.
Local storage: Phones still don’t come with massive “hard drives” found on laptops with 500GB or 1TB of data. Sizes between 16 and 64 GB are more common - and that’s not a lot when you record lots of videos, download shows, or use the “Offline” feature from Spotify. Our App Report shows you not only these top space grabbers but also the silent hoggers that could save hundreds of MB or even some GBs on your phone without you knowing.
So what are the top ones in each category? Let’s find out.
Top storage-hogging apps
We have separated our findings into two categories: 1) apps that run at startup and in the background, and 2) apps that are run by the user. The first type starts draining your resources as soon as the phone is turned on, and the second needs you to actively use an app, such as downloading songs on Spotify
Looking at those apps that amass data and eat up smartphone storage in the background, the number one offender is Facebook, which collects caches every time it’s running and forgets to delete them. Obviously Spotify is on that list, too, as it tends to download podcasts and songs in the background. So keep on eye on what you sync offline.
In the “Run by you” category, chat apps, shopping apps, and also Google Earth stand out. So you’ll want to keep a look out for those drainers, or, if you’re not using them, get rid of them.

Top data traffic-hogging apps
The following list reveals the top apps that consume mobile data, which should be useful for users who wonder why their mobile data keeps running out before the end of their billing cycle.
For the last year, Netflix has been the app that consumes the most megabytes (if not GB!) of data. Streaming an average-sized movie or TV show can easily require 200-500 MB — and more if users choose to stream at a higher quality. To avoid losing mobile data, users should only stream when connected to Wi-Fi, or opt to download TV shows and movies while connected to Wi-Fi to view later.
