S25 Ultra battery drain

[krg21]

I bough the S25 ultra 512gb, On the first day, I charged it to 100% after doing the transfer from smart switch and I got almost 6 hours of SoT, I drained it to 0%, and after that I'm getting max 5 hrs of SoT in my everyday use, it is my 4th day today. 
i had done the transfer  through smart switch from my S24 ultra. also the "learning usage pattern" disappeared after a day or two. 
I don't know why i am getting such less SoT and battery back up. I've read on forums that others are getting around 9 to 11 hours of SoT. 
what should i do?

Guys I think I figured out what is going on. Apparently smart switch is doing copy paste every single thing on the new phone.

I came to S25U from S22U and the first thing I did was to transfer everything with smart switch. I was and still am struggling with battery life as I wouldn't get more than 5-6 SOT per day without having to recharge the phone. I read a lot of people complaining about the same thing and. I turned ram plus off wiped cache put into light profile turn to 4g instead of 5G turned off NFC etc etc. The thing that I noticed was the major apps that I was using example Facebook- messenger- WhatsApp- viber -tik tok I Uninstalled them all and installed them again. On the new installation I noticed some tiny minor details like icons appearance etc etc that they were not the same as before . 

So I think that smart switch directly copies them as they were.

The apps for one ui 7 and s25 ultra seem different if you install them manually and no transfer them.

There is a high possibility that the apps transferred from another phone are not optimized for S25U and missbihave as far as battery drainage is considered.

So at this point a factory reset and clean install on the phone is the most effective solution. Back up your phone and transfer contacts and images only .

ALL THE APPS INSTALL THEM MANUALLY!!!!

I’ve found out the solution 

I tried so many things 

what I first tried was to activate air plane mode before sleeping and activating WiFi and Bluetooth 

it worked very well 

on the 2nd day I closed only the mobile data with activation of WiFi and Bluetooth 

it didn’t work 

so I knew that the problem was from the eSIM 

What i finally did and worked very well 

1- I replaced my eSIM 

2 - I created a sleeping mode 

in which the network prefer lte 

close mobile data 

activating power saving mode 

closing NFC 

during sleeping hours 

it worked very very well 

the battery discharged by only 4% during 8 hours sleeping .

The main problem of most people is not during night but the actual screen on time thing.

When you use your phone the most.

On standby mode most cases where good .

And yes leaving wifi only and turning on airplane mode helps a lot if you leave in an area where the signal is not good and you phone is struggling to find good signal.

If your carrier supports wifi calls then its worth it.

Do you lose your esim with a backup to samsung cloud

[Pantelis83]

Yes.You must have the Qr code from your provider to activate it again
