My mobile is S21 Ultra Snapdragon, I got 1 GB size update 2 days ago, but after this update the battery performance has been decreased.
Before the update, the battery was giving 1 hour Screen On Time per 10% consuming, which is 10 hours SOT in total, based on my personal use.
But after the update, the performance has become far less than that, it gives now around 8 hours in total, which is not dependable in all the day for me!
Now I'm glad I have the exynos version. I hope the issue gets sorted tho, not sure if it's the ai reworking your usage from scratch and trying to estimate your battery life.
