In a new study of over three million Android devices, researchers at cyber security firm Avast, based in Prague have come up with a list of the 'greediest' apps on Android (stock image).
If your Android is slow, eats through mobile data or frequently runs out of storage space, it could be time to delete some of your apps.
Mobile apps use up digital resources even when they're not in use, and could slow down the performance of your phone.
In a new study of over three million Android devices, researchers have created a series of lists of the biggest drainers, which include Google Maps, Google Play Music, and Samsung AllShare.

Avast has offered a list of tips for boosting battery life, managing storage consumption and saving mobile traffic:
- Restrict notifications so you only get alerts about the things that matter
- Limit background features, refresh intervals, location usage or in-app notifications
- Clear your cache and remove temporary files
- Turn off background data transfers or any offline reading features
- Turn off Wi-Fi, Bluetooth and GPS when you're not using them
- Turn down the brightness of your screen
The report, from cyber security firm Avast, based in Prague, found that Google's own apps are among the worst offenders.
Google Maps, Google Play Music, Google Plus and Google Hangouts all appear in the list of top 10 'greediest' apps that drain performance.
Many of these apps come pre-installed on Android devices and launch automatically when your phone is turned on.
They then run in the background even when you aren't using them.
Other pre-installed apps found to be a big drain on smartphone performance include several provided by Samsung, such as AllShare, ChatON and Push Service.
Apps that are activated by the user and run in the foreground were also covered in the study.
Researchers found that Google Docs and Text-to-Speech are among the greediest, along with Samsung WatchON, Video Editor and Media Hub.
Several third-party apps also featured in the top 10 user-activated performance drainers, including SHAREit, Flipboard, Line and Adobe Acrobat Reader.
When Avast took a more in-depth look at how different apps affected battery life, storage capacity and data usage, some familiar names surfaced.
Facebook was found to be the worst app for consuming your mobile data, and for taking up space on your phone.
As well as apps that run as soon as the phone is switched on, the researchers also looked at which apps run by users drain performance most (pictured). Many of the apps are made by Samsung and Google and come pre-installed on Android devices
1) Spotify Music
3) LINE: Free Calls and Messages
4) Video Editor
5) SoundCloud - Music and Audio
6) PicsArt Photo Studio and Collage
7) Amazon Shopping
8) BBC News
9) Clean Master
10) Photo Grid
Chat apps including WhatsApp, WeChat and Snapchat are heavy battery drainers, as are streaming apps like Netflix and Spotify.
Instagram, Facebook Messenger and Snapchat all take up a lot of storage space, as do text-heavy applications like Amazon Kindle and the BBC News app.
Netflix and Spotify are unsurprisingly the most likely apps to dry up your data allowance.
Avast found that web browsers like Chrome, Firefox and Microsoft Outlook also have a big impact on mobile data.
'For many of us, our smartphones are the main device in our everyday lives,' said Gagan Singh, senior vice president and general manager of Avast's mobile business.
Samsung's own pre-installed apps were the top four 'battery drainers' that run at start up, with Google Maps coming fifth. The app DU Battery Saver was ranked in the top 10
Unsurprisingly, streaming services such as Netflix and Spotify were two of the biggest battery-drainers run by users, with Samsung's video editing software also coming in the top five
'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.'
As part of its report, Avast offers some advice to those looking to boost their phone's performance but who are hesitant to remove their favourite apps.

The firm recommends you restrict notifications so you only get alerts about the things that matter, and limit background features, refresh intervals, location usage or in-app notifications.
Clearing your cache and removing temporary files is another way to boost phone performance, as well as turning off background data transfers or any offline reading features.
Finally, Avast recommends you turn off your Wi-Fi, Bluetooth and GPS when you're not using them, and turn down the brightness of your screen.
