Battery Life is a major concern in today’s modern world. Everyone relies heavily on electronics, from laptops to tablets and especially the smartphone. All these platforms use a battery and manufacturers, as well as consumers, are constantly trying to get the most out of their battery.

Sometimes this means placing a bigger battery in the device. However, as we saw with Samsung’s Galaxy Note 7, this can sometimes come at a price. Other tactics include throttling hardware performance to either save power or extend the overall lifetime of the battery. At times this is done secretly in the background of the device and other times it is implemented as a setting in the device operating system.

This last one has become a real trend across the board. Microsoft Windows has the feature, Apple’s IOS has it, and of course, Samsung uses it as well.

Samsung’s power saving mode is one of the best.

After using several devices, I have to say Samsung’s Power Saving mode is very effective. I have used it on both the S8 Plus as well as the Note 8, and it just works. The option can be found in a few different places. There is a toggle in the quick access section of the notification panel. It is also located in the settings, under device maintenance in the battery menu. The option is also prompted when your battery falls below a certain percentage. Many device owners have enabled this feature countless times. Whether stuck in traffic or after a long day at work, people are constantly using this to squeeze a few extra hours out of their dying device when away from a charger.

But what does power saving mode do?

There are two different power saving modes on a Samsung device. There is a medium mode which does several things. The two big differences for this mode are that it disables background data usage and limits the processor speed. These do affect the performance of the device. The device will run slower and experience a bit of lag. It also will prevent you from getting notifications from apps that use the internet connection. This means you may miss some notifications unless you open that specific application. Obviously, SMS and phone calls are not affected. Finally, it makes a few other albeit less noticeable changes. It decreases screen brightness by ten percent and will also switch the screen resolution from ultra HD to full HD plus.

Then there is the max power saving mode. This toggles all the same actions as the medium mode and then some. This function will completely change the UI of your device. It only allows certain apps to be used, removes transition effects when you switch between screens and places a flat black background on the home screen.

It changes the resolution to HD plus and disables all biometrics (fingerprint, iris scanner and facial recognition). Although this mode dramatically changes your device, it absolutely will increase your battery life by hours.

These modes are highly effective. The different choices are a nice touch that allows the user to decide how much they need to sacrifice depending on their situation.
