In a comment on our article about how some free apps drain your battery power, Nick asked: How about doing a series of stories on the free apps that use the most battery power, interrupt you the most often, interrupt you for the longest periods, hog the most resources, send your personal data out to other advertisers, modify your computer’s settings.
That task could prove difficult for a small company. Downloading a hundred different apps to compare would take a lot of time, effort and more manpower than we could muster. But it’s pretty easy for you to find out which apps are taking up the most resources on your device.
On an Android phone or tablet choose settings.
Then look for the Data usage icon and tap it. On my phone it is Settings under Connections.
Scroll down to a list of apps that use data and how much they use.
You can tap the icon for the app to see more information.
You can also search for the Battery Icon in Settings. On my phone, you find it in Settings under More.
There I’ll get a list of what’s using the most battery power on my phone.
I can tap any of those icons for more information.
As far as interruptions, the acceptable level of interruptions in an app is really something that only the user can determined. If a free app annoys you, that’s too many interruptions. But it’s possible that you may enjoy an app such as Words With Friends enough that you don’t care if there’s a commercial at the end of every turn.
You can find out what type of information an app shares and the modifications it makes to your device’s settings before you download it. You have to grant permission for all that to happen. So make sure to actually read the permissions and don’t tap that install button without checking. You can find detailed permission information in the Google Play Store.
Make sure to read those permissions before authorizing them.
To learn more about the permissions you’ve granted to apps already installed on your device, go to Applications Manager under Settings. Tap on any app you’re curious about.
Scroll down to read the permissions you’ve granted the app.
With this type of information, you can decide which apps are worth keeping on your phone.
