How to use and customize power mode on Galaxy S20?

By simon Leave a Comment Last Modified: January 18, 2021 · Published on: December 2, 2020

use and customize power mode on Galaxy S20You can use Galaxy S20 power mode to balance the performance and battery life based on your needs and habit.

This Galaxy S20 guide explains the importance of using the proper power modes on Galaxy S20, what are the 4 power modes on Galaxy S20, when and how to use each of these four power modes. The guide also shows you how to manage, customize, and limit battery usage (and background activities) for individual apps from app power management and application managers.

Samsung adopted almost identical power modes (power-saving modes) on all Galaxy Phones with Android 10. So, in addition to Galaxy S20, Galaxy S20+, Galaxy S20 Ultra, and Galaxy S20 FE, this guide also applies to most of the recent Galaxy phones, including all variants of Galaxy S10, Galaxy Note 20, and  Galaxy Note 10.

Update: Samsung introduced the Enhanced processing option under battery settings in Android 11 update for Galaxy S20.

Why is Galaxy S20 power mode important to balance performance and battery life?

Battery life is a major concern for many Galaxy S20 owners, although Galaxy S20 supports up to 45W super-fast charging and fast wireless charging 2.0.

Most of Galaxy S20 owners expect the phone worked when they want to use it. Running out of battery can be very disturbing nowadays, especially if you pay more than $1000 for the gadget.

Unfortunately, current Li-ion battery technologies still pose a hard limit on the battery capacity given the limited available space in the phone and possible and safety considerations.

So, one way to extend battery life so that you have enough battery before you can access a charger is to “save ” battery, i.e., reducing or optimizing the usage of the battery.

Basically, it is not necessary to let the Galaxy S20 run at its peak performance. For more than 90% of owners of Galaxy S20,  the phone offers more processing power than what you need.

Even for heavy gamers, the high processing power is only needed when you play some large games. You do not need to keep the phone running in its peak state all the time.

Power mode in Galaxy S20 lets you balance the performance and battery life.

What are the 4 power modes on Galaxy S20?

On Samsung Galaxy S20, there are 4 power modes:

  1. Optimized (default).
  2. High performance.
  3. Medium power saving (aka, power saving)

How to set Galaxy S20 display refresh rate?

By simon Leave a Comment Last Modified: December 3, 2020 · Published on: June 2, 2020

set Galaxy S20 display refresh rateThe 120Hz display refresh rate is one of the prominent new features of Galaxy S20.

This Galaxy S20 guide explains the role of the display refresh rate on Galaxy S20, how to change the refresh rate on Galaxy S20, the limitations of the 120Hz refresh rate on Galaxy S20. Some questions you may have on this feature are also addressed.

The display refresh rate feature on three Galaxy S20 phones are identical. So, S20 in this refers to Galaxy S20, S20+, and S20 Ultra.

What are the 60Hz and 120Hz display refresh rate on Galaxy S20?

The display refresh rate measures the number of times per second the display can redraw the whole screen. So, the unit of the refresh rate is Hertz (Hz, 1/s).

For most smartphones, the display refresh rate is 60Hz. And it is good enough for most users.

Most videos have a frame rate of 24~30 fps (frames per second).  Loosely, you can think one frame means one static image on the screen.

So, as long as the refresh rate is higher than the fps of the video, we say the display can handle the video. You can watch the video on such a display.

In reality, the 60Hz display refresh rate allows you to watch the video smoothly.

But some users, mainly gamers,  may prefer a higher refresh rate to enjoy more realistic gaming experiences.

The hardware and the software on Galaxy S20 are capable of generating graphic output at very high speed, far higher than 60fps even at the full WQHD resolution.

So, some games can benefit from the high fps if the display can handle the output smoothly.

Galaxy S20 answers such demands with the 120Hz refresh rate display.

As mentioned, the 120Hz refresh rate is not for everyone. You will see the difference if:

  • You are playing 60fps (or higher) videos.
  • You are playing a few games that can handle/generate output at a rate higher than 60fps. Most games do NOT benefit from a high frame rate.

Anyway, as a new feature of Galaxy S20, the 120Hz refresh rate display (motion smoothness) may improve your experiences with a few games and videos.

How to set the Galaxy S20 display refresh rate?

By default, the Galaxy S20 display refresh rate is et at 60Hz.  You can change it to 120Hz in the motion smoothness settings.

Please note, the 120Hz refresh rate is not … Read the rest
