Even after decades of technological advancements from now, there will always be bugs in the software of a device. These get fixed by the manufacturer and they release software updates for the same to be implemented in the users’ smartphones. Hence, keeping your device’s software updated is a must.

Quick Tips to Improve Samsung Android Phone Battery Life
But with great updates comes greater grief, like faster battery drainage. This article lists below some of the ways to improve battery life in Samsung One UI 3.0 Android devices.
Enable Dark Mode/Night Mode
In order to prevent the battery from draining rapidly, enabling Dark Mode is a great way. Dark Mode not only saves the battery but also causes less strain on the eyes due to the reduced brightness of the screen. Most of the Samsung devices, like the Galaxy Note series, come with an option to enable the Dark Mode. For those devices that don’t, any dark or black theme can be applied as it serves a similar purpose. It has been found that the battery of a device is consumed up to 38% less depending upon the brightness of the phone.
To enable the Dark Mode, enable the option from the notification panel.

Disable Always On Display
One UI has a feature called Always On Display that shows a customized screen displaying the date, time, and notifications. The time period for this function is between 05:00 AM and 10:00 PM. Enabling this feature only results in higher consumption of the battery for no good reason. For the battery of the Samsung device to last longer, the ‘Always On Display’ option should always be OFF, ironically!

Enable Adaptive Brightness
Adaptive Brightness helps the mobile device adapt to the amount of light in your environment. It sets the brightness of your mobile phone accordingly. For example, if you use your device outside on a sunny day, the brightness of your mobile phone will increase automatically, making it easier for you to view the contents of the screen. Similarly, the brightness of the phone will automatically reduce in a dark room to prevent causing strain in your eyes.

Use Power Saving Mode
To optimize the performance of your Samsung device and make the battery last longer, enable Power Mode or Power Saving Mode. Though this limits the features available in your smartphone and restrains you to use only the basic features, Power Saving Mode can come in handy to make your device sustain for longer. In One UI 3.0, you can choose from three power-saving modes and select the one that best suits your needs.
To enable the power saving mode in Samsung Galaxy devices, follow the steps given below:
- Navigate to Settings > Battery > Power Mode.

- Choose an option that you like from Optimized, Medium Power Saving and Maximum Power Saving.

Toggle Off Fast Charging
Much to our surprise, the fast charging technology actually degrades the quality of the battery. This, in the long run, results in its fast discharge. If you do not wish to change your mobile phone in the near future, disabling the fast charging option is something you should definitely consider as that will help you to improve battery life in Samsung One UI 3.0 devices.

Uninstall Apps You Don’t Use
One of the reasons why your device’s battery life drains quickly could be the applications that you don’t normally use but they run in the background to perform a few operations. They consume processor resources and slowly deplete your battery.
Once you’ve decided to let go of these apps, follow these steps:
- Go to the Home Screen.
- Long Press the app you wish to uninstall.
- Tap the Uninstall button.
Turn Off WiFi, Location, and Bluetooth
When not in use, you should always disable Wifi, Bluetooth, and Location in your device as they check for a signal in regular intervals which in turn results in power consumption and drainage of the battery. To do this, pull down the notification panel from any screen on the device and turn them off.
