For some users, the Galaxy S20 battery drains too quickly.
Some people may try to turn off 5g and start a 96Hz screen refresh rate. Some people may wish to further delete the Samsung apps built into the firmware, such as Samsung Browser, Bixby, Samsung Pay, etc., to further reduce apps running automatically in the background and reduce power consumption.
The following method is theoretically suitable for all Android phones. You only need to know the name of the App package built into the firmware through software or other methods, and you can delete it through the adb command without affecting the OTA upgrade.
Here are the steps:
1. Get the adb driver of PC, mac or linux computer, please check: https://www.uso.cn/post/view/1084
2. Open the developer options of the Galaxy S20 and other devices, turn on USB debugging, connect the computer and mobile phone, and select OK in the pop-up window.
Continue to observe the phone, and the pop-up window chooses to trust the computer.
3. Open the command prompt on the PC, if you are using a mac, open the terminal, enter the command "adv devices".
4. Then enter "adb shell."
5. Here is the important point. The following is a list of the built-in apps you want to delete. If you want to delete them, simply copy them (excluding the bank)
