ZDNET’s key takeaways

  • If you have limited mobile data, pay attention.
  • This feature could save you money.
  • You control whether apps can use data in the background.

For some people, the idea of saving and controlling data usage on a phone isn’t really an issue. If you don’t happen to have an unlimited data plan, it’s a different story. I’ve been in situations before when my phone warns me that I’ve exceeded 2GB of data (I can’t remember how much data my plan gives me). When that happens, I tend to put the brakes on.

When those instances happen, I’m glad Android makes it easy for me to take control of data use. In conjunction with stopping Android apps from running in the background, you’ll have more control than you ever thought you could enjoy.

If that sounds like something you could use, read on, and I’ll show you how easy it is.

How to use Data Saver mode on Android

The first thing you’ll want to do is enable the Data Saver mode, which prevents some apps from sending and/or receiving data in the background. What does that mean? For instance, if Data Saver is enabled and you visit a website in your browser, images won’t load until you tap them. Additionally, videos and audio will not play automatically.

Here’s how you enable the Data Saver feature.

Open the Settings app by either pulling down the Notification Shade twice and then tapping the gear icon at the bottom right. Another option is to open the App Drawer, search for the Settings launcher, and tap it.

From within the Settings app, go to “Network & internet.” On that page, locate and tap Data Saver. Note: On some Android phones, the feature is found in Settings > “Mobile network.”

Always remember to turn Data Saver off when it’s not needed.

On the resulting page, tap the On/Off switch for Use Data Saver until it’s in the On position.

At this point, Android will restrict background data usage, so you shouldn’t have to worry so much about going over your limit.

Here’s the kicker. When you enable Data Saver, every app you’ve installed will be subject to its restrictions. That’s great, but you could run into apps that don’t function properly. Should that happen, you’ll need to allow that app to bypass that data usage restriction.

This is quite simple. On the Data Saver page, you’ll see an option labeled “Unrestricted mobile data.” Tap that entry.

You should now see a list of all the apps you have installed on your phone. Scroll through that list, find the app that needs to ignore the restriction, and tap the associated On/Off slider until it’s in the On position.

Make sure to enable all apps that will only function properly without the Data Saver feature enabled.

One thing to keep in mind is to disable Data Saver when you’re no longer at risk of exceeding your data limit.

And that’s all there is to saving data and controlling data usage on Android.

If you’ve bought a new Raspberry Pi, or just got your hands on an older model that someone else didn’t want, there are many ways to put that little computer to good use, and here are six of them.

Retro gaming galore

One of the most popular uses for Raspberry Pi computers is as a retro gaming emulation system. Which systems can be emulated depends on which specific model of Pi you have, but even the oldest ones can do a great job with retro 8-bit and 16-bit titles, or MAME arcade titles. In fact, building your own arcade cabinet with a Pi at its heart is a common project, and you’ll find lots of instructional guides on the web to that effect.

Build your own NAS

A NAS or Network-Attached Storage device is effectively a local file server that lets you store and access data on your local network using hard drives. You can go out and buy a NAS or you can follow the official Raspberry Pi NAS tutorial and turn your old USB hard drives into a NAS using stuff you already have, or can get for just a few dollars.

Everyone loves local streaming tools like Plex or Jellyfin, but not everyone wants to dedicate an expensive computer to act as the streaming server. Well, as long as your requirements aren’t too fancy, you can use a Raspberry Pi as a Plex server.

Just don’t expect it to handle heavy-duty transcoding. The good news is that most of your client devices can probably play back videos without the need for transcoding.

Turn your Pi into a home automation hub

Home automation hub devices can cost hundreds of dollars, but if you have an old Raspberry Pi, you can run your smart home off it. The most common and effective solution is an open-source app called Home Assistant.

Build a weather station

If you’re interested in the weather, want to contribute to weather data, or are just sick of getting rained on when you least expect it, you have the option of getting a weather station kit for your Raspberry Pi or using something like the Raspberry Pi Sense HAT, which can detect pressure, humidity, and temperature, but not wind speed. However, there are also generic wind and rain sensors you can buy, and, of course, don’t forget an outdoor project enclosure.

There are a few guides on the web, but this weather station guide for Raspberry Pi is a good place to get some ideas.

Create a home web server

Another fun project to do is hosting your own little web server using a Raspberry Pi. You can make a website that only works on your home LAN, or even host something that people from outside your home network can access. Using open source software to host your own web resources is highly educational, and it can also be a way to do something genuinely useful without having to rely on a cloud service somewhere on the internet.

Imagine having your own little bulletin board at home, or hosting content like ebooks, music, or audiobooks?


Infinite possibilities

Despite lacking in the raw power department, all Raspberry Pi devices are little miracles—single board computers that can (in principle) do anything their bigger cousins can. Just more slowly. So if you have a few old Raspberry Pis hanging around, don’t be too quick to retire them yet.
