I updated to one UI7 last night and now my battery while on idle is draining extremely fast. 

 
Had I known this would be an issue I would have never updated to this crappy software. 
 
This is a major issue and like I said I can notice the extreme battery drain while the phone is idle.
 
If Samsung doesn't fix this issue I will be filing a claim as to me this is now a defective item that they caused.

Everyone's battery is 40% of what it was.
Also the phone gets so hot you can't hold it anymore this is a real problem I wish they would get it right one time

Definitely confident that location is a contributor to this unbelievable battery drain that we've all complained about. I can say that I've noticed that dark mode constantly staying on dramatically impacts that as well. I turned it on instead of scheduling, and my battery is on a more controlled/normal usage decline. I've been pretty good about going into device care & optimizing when needed, closing apps, and even smart wifi to turn off until I'm in range of a certain network. Has anyone else found tricks around battery management since the new update?

Before the new ui 7 update I would only have to charge my phone once a day but now I need to charge it 2-3 times! Please fix this issue, I'll rather have better battery life before any of these new features

Ya I updated last week and ever since my 24 Ultra has drastic drain. Could go half a day and it would go down to like 75 percent. Now by lunch I'm down to 50 percent

After update to new system, battery life was shortened, didn't last all day.

I've have been patient waiting for a fix, but today, after phone was charge to 80% using the battery save mode, woke up unplugged the phone, went to the gym and store errands without using my phone for any calls or music while working out, neither social media or watch videos. To make the story short, phone was idle all this time, from unplugging the phone 3 hrs ago to now, from 80% battery to 38%. **bleep** is happening? WE NEED A SOLUTION ASAP.
