Practical scenario: Users with Samsung Galaxy S9 Plusbattery life problems

S9+ Low battery

Today I bought the S9+, and I can see how the battery percentage dropped to 80% when I installed the phone, which took me about half an hour in total, while the blue phone was off.   The simple fact that it is always displayed on the screen is enough to reset it with a few percent within an hour.   Since the fall rate can not see that it takes more than half a day of normal use is not sure that you get an hour if you do something really intense, such as z.

Pay attention: These tips apply to all Samsung Galaxy mobile phones, including B. Samsung Galaxy S9/S9 Plus, Samsung Galaxy S8/S8 Plus, Samsung Galaxy S7/S7 Edge, Samsung Galaxy S6/S6 Edge, Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy J Series/A Series, Samsung Galaxy On Series, Samsung Galaxy Note 9/8/7/6 and all other Samsung Galaxy phones on the market.

That’s an important clue: The settings may vary from one phone to another, so it is recommended to find the settings according to the Samsung Galaxy phone settings.

All right, let’s go!

Tip 1: Manual adjustment of screen brightness

It’s just common sense. The brighter the screen, the more power the phone consumes. Let me tell you that the Samsung Galaxy is equipped with an automatic brightness function that automatically filters the brightness of the screen and adjusts to daylight and low light conditions, but uses more battery power.

Therefore, it is suggested to manually adjust the brightness of the screen and disable the auto brightness function.

To adjust the brightness level :

  • Go to Settings > Brightness.
  • Here you can turn off the automatic brightness and adjust it manually.
  • Adjust the brightness level in the middle or bring it a little closer to the minimum, but still bright enough to read.

You can also adjust the brightness level by dragging the notification bar down and adjust the slider to suit your needs.

Tip 2: Activating the low-power mode

Activating power saving mode really helps you to improve and expand the spare battery of your Galaxy phone.

The battery saving mode optimizes screen resolution, brightness, processor speed and network utilization and stops the process in the background, increasing battery performance.

This section describes how to activate the battery save mode:

  • Go to the Quick Setup menu.
  • Touch the power saving icon.
  • Here you can select one of the specific presets or set the amount of energy you want to save manually with individual settings.

Tip 3: Turn off Always on. Display

Although some of Samsung’s Galaxy AMOLED displays are very efficient and do not use power to display black pixels, the Always ON display still consumes some power.

Turning off the Always ON light will definitely help you save a few percent extra battery charge at night.

This indicates how to turn the indicator always on:

  • Go to Settings.
  • Click on Lock Screen and Security.
  • Turn off the display permanently.

Tip 4: Decrease in display resolution

On most Galaxy phones, such as the Samsung Galaxy S8/S8 Plus, the screen resolution is set to 2220 x 1080, but can be set to a higher screen resolution of 2960 x 1440. Installing a higher resolution display looks good, but it also consumes more CPU energy to evaluate each additional pixel.

So if you’re more energetic, you really need to keep screen resolution to a minimum, which can help you save an extra battery.

Here you can learn how to lower the screen resolution:

  • Go to Settings.
  • Press Display.
  • Select the screen resolution.
  • Go to 1480 x 720.

It is therefore recommended to turn off Bluetooth and NFC when they are not needed.

Learn how to disable Bluetooth and NFC:

  • Go to Settings.
  • Press Connections.
  • Then deactivate the Bluetooth and NFC functions.

  • Go to Settings.
  • Press Display.
  • Select Timeout on the screen.
  • Set the waiting time on the screen to 15 or 30 seconds.

Tip 7: Vibrations and noise of

Muting sound and vibration is another basic function that helps you save your Samsung phone’s battery. After all, every time you make a call with your phone or receive a message, it consumes energy to pump out the sound and start the vibration motor.

So try to muffle the sound and vibration of the phone.

Below you will find information on how to turn off sounds and vibrations:

  • Drag the notification window down or open the Quick Install menu.
  • Click on the small speaker icon (also called the mute icon).

A complete GPS/Location switch-off really helps you to save even more energy.

Here you can learn how to disable the GPS:

  • Go to Settings.
  • Scroll down and click on the option Location.
  • Then press Location Method.
  • Finally, select the Save battery option.

Other tips for charging the battery

For those of you who don’t know, we would like to provide some knowledge about increasing the number of battery cycles.

What is the number of cycles?

The number of cycles corresponds to the battery charge of 0% or close to zero to 100%.

On average, most lithium batteries, with a few exceptions, have about 350 to 500 cycles. This means that if you charge your phone between 0 and 100%, the battery won’t deliver the same backup battery after 500 recharges, and it can just hold 70-80% or less of what you received in the beginning.

In some of the worst cases, if the battery life is only 350 years and you charge your phone once a day, you will notice after a year that the spare battery in your phone has decreased significantly.

The question now is how to extend the life of lithium batteries.

There are three ways to extend battery life:

  1. Charge your phone with the slow charger. The slower your phone charges, the slower the battery charge. Today we can find a quick charger that can charge your phone’s battery in just a few minutes. It is therefore advisable to avoid such a quick charger.
  2. Never lower the phone battery to 0%. You should connect the charger at about 5-10%.
  3. This is very important: NEVER charge your phone 100%. If you start charging your phone at 5%, charge it to 85-90%, only then can you expect the lithium battery to last up to 1000 cycles. And if you charge up to 75-80%, you can increase your lifecycle up to 2000 cycles.


So here are the basic tips and tricks you should follow to increase/extend the battery life of your Samsung Galaxy phone or to improve the backup battery.
