My Galaxy S20 FE (on T-Mobile/Sprint) just received an OTA update (which said it was only One UI). Current About says
One UI: 3.0
Before the update, I was getting nearly a day-and-a-half on a full battery charge.
Now, after the update, I'm getting just over half-a-day.
The update has cut my battery life in 1/3rd.
How do I roll back to the previous version. This is ridiculous. I certainly don't want this update if it effects my battery life like this.

Same problem here. Got a S20 Ultra in November. After use for a full day it would never have less than 70% charge in the evening. After the latest firmware update it gets down to 20-30%. Trying to add up the percentage of which apps is using the battery gets me at 20%. So there is still 50% batterylife which isn´t accounted for.
Same issue with battery drain since the most recent update. The battery drains quicker than normal, then when gets to 15% battery life remaining the battery percentage indicator will literally click off like seconds off a timer down to shutting off within a matter of 20 to 30 seconds from when hitting 15% remaining.
