Battery life is more important than ever for phone users. We use our phones every day, all the time, and we’re glued to what we see on our screens. Without optimizing battery life and planning for the day ahead of us, we may not have our phone available to use when we need it the most.

While the Samsung Galaxy S7 and S7 Edge improve upon the battery life issues with the S6, they come close to matching the S5’s battery life and optimization features.

Get the Most Out of Your Samsung Galaxy S7 Battery Life

Understand How Battery Life Works

Battery Usage by Apps

Most of us are familiar with how battery life works on mobile devices now. It’s simple, really. The more you use the phone, the more battery you’re using; if you’re playing games, recording videos, or talking on the phone, you’re using more battery than performing simpler tasks, like browsing the web or texting a friend.

The Samsung Galaxy S7 and S7 Edge show you how your battery is being used between charging sessions. This is useful for determining what apps and services are using the most battery. You can change your phone use habits based on this data in most cases and get the most out of your battery life on the go.

Bad Battery Life Habits

There are a few habits we’ve picked up since using mobile phones that are actually detrimental to battery life, including:

  • Closing apps through a task manager
  • Restarting your phone to speed it up
  • Turning your phone off for and removing the battery for ten seconds to speed it up

Closing apps can actually make your battery work harder, because they have to close the app entirely and clear it from memory and then re-open the app the next time you use it instead of keeping it in memory the entire time.

Restarting your phone and/or turning it off uses more battery to turn it off and then turn it back on again.

If you’re running low on battery, the above options actually use more battery and don’t help optimize it at all, especially below 30 percent of battery life.

Built-in Optimization Features

The Samsung Galaxy S7 and S7 Edge offer three distinct built-in battery optimization features. Two of which S5 and S6 users will be familiar with: Power saving mode and ultra power saving mode.

Both of these power saving modes have had features changed and tweaked from the earlier versions.

Power Saving Mode Details.

Power saving mode limits your phone’s performance, location services, and background data which greatly improves battery life over time. You’ll manually sync any apps you need updates from, such as Facebook, Gmail, and others.

Ultra Power Saving Mode Details.

Ultra power saving mode puts your S7 into the “grayscale” mode, as I like to call it. When this is turned on, everything that occurs with power saving mode is in effect along with limiting a variety of apps to basic functionality. This can make your battery last for four to five days in most cases.

Battery Optimization Options.

A new feature with the S7 and S7 Edge, thanks to Android Marshmallow, is optimizing specific apps for battery usage. This restricts background data and sync capabilities for specific apps to ensure they’re using as little battery as possible.

Portable Batteries & Charging On the Go

The Galaxy S7 and S7 Edge use fast charging to get you going much quicker. In Samsung’s mind, you can still charge on the go with little fuss but unfortunately, this just isn’t practical. Unless you have access to a wall outlet for up to an hour, you won’t be able to charge your phone to full juice. You may be able to charge it enough to get by but you still may need to limit what you do.

If you are using a regular charger, and not the fast charging adapter that came with the phone from Samsung, you’re going to get a much slower charge. Keep that in mind when you’re on the go, too.

Portable batteries are becoming smaller, thinner, and more powerful than ever. We’ve reviewed quite a few at TechNorms, and this can be a quick way to charge on the go. Invest in a powerful portable battery and stay charged on the go, optimizing your battery life combined with on the go charging, you’ll be good to go no matter what you’re up to for the day.


The key to getting the most out of your battery life on the S7 and S7 Edge is to learn your habits and work around them. Whether you’re a gamer, a talker, or a YouTuber, there’s ways to stay charged on the go and ensure you have the battery life you need wherever you are.

While the battery life is good on the S7, it’ll be even better when you optimize and get smart about how you charge your phone.
