How to make the most out of your Galaxy S7 battery

How to make the most out of your Galaxy S7 battery

By Samsung Australia,  15.06.2016.


There are few things more useless than a smartphone with a flat battery.

To ensure you stay in touch, the Samsung Galaxy S7 and S7 edge feature two power saving modes designed to extend your phone’s battery life, especially when it reaches critically low levels. These in combination with some unique power setting options and ultra-fast wireless charging will keep you powered whenever and wherever you are.

Power Saving Mode

Power Saving Mode

As a first step to prolonging your battery life, you can switch your Galaxy S7 to Power Saving Mode whenever you like. Alternatively, you can set your phone to automatically activate this mode when the battery charge drops below a certain level.


Power Saving Mode will limit your phone's performance somewhat and restrict use of the GPS (location services) and most background data, but you should notice little difference in how well your phone functions.

Ultra Power Saving Mode

When things get serious, it's time to activate Ultra Power Saving Mode. In Ultra Power Saving Mode, the Galaxy S7 reserves all its power for making phone calls, sending messages and accessing the internet, and little else beyond that.


Most apps are automatically deactivated in Ultra Power Saving Mode, although you can select from a list of important predefined apps, such as Facebook, Whatsapp and more.

In Ultra Power Saving Mode, the Galaxy S7 also deactivates Wi-Fi and Bluetooth, and switches off your mobile data connection while the screen is off.


This significantly reduces demands on your battery - Samsung says a mere 10 per cent battery charge should be enough to keep you connected for up to 24 hours in Ultra Power Saving Mode, depending on usage.

At the bottom of the screen, your remaining battery power and estimated battery running time is displayed when in Ultra Power Saving Mode.


The time displayed is the estimated maximum standby time before the battery power runs out with the phone idle.

The most obvious change you'll notice when Ultra Power Saving Mode is on is that your phone's display switches from full colour to black and white.


Samsung's advanced AMOLED screen uses no backlight. A black pixel is simply off, and therefore uses no power at all. By changing to a black and white display, the Galaxy S7 is able to light up far fewer pixels, reducing power usage substantially.


The AMOLED screen has a very high contrast level, so the black and white display — while not quite as visually appealing as the full colour version — is still very readable and functional.

You can also access more information about the Galaxy S7's battery in the Settings menu.


Here you will also find the App Power Saving function, which automatically optimises power usage for apps that have not been used for three days (or a different period as defined by you). This prevents unused apps from needlessly draining your battery.

Ultra-fast wireless charging

A great way to keep your Galaxy S7 charge levels up is with Samsung's Fast Charge Wireless Charging Pad, which can be used in conjunction with the Galaxy S7 and S7 edge.


This not only puts an end to tangled or lost charging cables, it also recharges your phone significantly faster than conventional charging by wire.


The charging stand is always at the ready, instantly providing wireless power whenever you place your Galaxy S7 onto it, and it holds your phone at a convenient angle so you can continue to use it during charging.


With all these options offered by the Galaxy S7 and S7 edge, your battery is unlikely to ever fail you again.
