How to change your phone screen resolution and refresh rate to extend battery life
Over the course of 2019, we have seen the release of many smartphones that support two basic features: the high-resolution screen, and increased the screen refresh rate to 90 or 120 Hz - such as: OnePlus 7 Pro phones, and Pixel 4 - which helped provide a better use experience, However, there was one issue, and these features negatively affected the power and battery life.
Here's how to control these two features on your phone to extend battery life:
First, how to change the screen resolution of the phone:
Whether you are using the Galaxy S10, or Pixel 4, or are you still waiting for the upcoming Galaxy S20 - expected to come with a WQHD + display with a refresh rate of 120 Hz - applying steps to reduce screen resolution Your phone is a quick and simple process, and you can do it as follows:
Open the Settings app on your phone.
Click on the (Display) option.
Click on the "Screen resolution" option.
Choose the resolution you want, and remember that: the higher the screen resolution, the clearer the texts will be on the screen of your phone, but this comes as we mentioned earlier at the cost of the phone's battery power.
Note: Not all phones support low resolution, for example (Galaxy Note 10) whose screen resolution cannot be changed to less than 2280 x 1080 pixels.
Second, how to change the screen refresh rate:
Not all smartphones support the screen refresh rate feature; the maximum refresh rate most smartphones can still reach is 60 Hz, including newer versions such as (Galaxy Note 10 Plus).
If you are using ROG Phone 2, Pixel 4, or OnePlus 7 Pro, reducing the refresh rate is an important measure to reduce battery drain. But setting it to 90 or 120 Hz will make the experience more smooth, and it can reduce pressure on your eyes. The screen refresh rate can be changed through the following steps:
Open the Settings app on your phone.
Click on the (Display) option.
Click on the "Advanced" option.
Press the (Smooth Display) option, and from here you can switch between stop or play to enable or stop the refresh rate on the screen of your phone.

It is worth noting that the (Smooth Display) option on Google Pixel 4 automatically changes between 60 and 90 Hz depending on what you do on the screen, and it is considered as a method of saving battery power. As switching to a 90 Hz rate is for playing games that require significant power and high resolution, while a lower 60 Hz rate is in normal phone use.
