I hate Samsung for doing this. I have a S21 FE Exynos in my house, the battery will not make it through the end of the day. The phone is always low on battery. The standby battery drain overnight is also noticable. To add burn to the injury, they are releasing the Snapdragon variant of the S21 FE now in my country, 18 months after the exynos variant was launched.
Why does Samsung keep doing this? Why do non US markets keep getting the shittier exynos models? We are the testing sheep for the Exynos chips while US gets the better stable models at also at a lower price. They SD phones are simply better in battery, OS stablility and Camera quality.
Also, do not delete the Ninite installer exe from your computer. It comes handy in updating all the apps at once. Just double click the installer again.
