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?

I used smart switch. I am having battery drain. says my battery will last 16hr 35mins on full charge. I am down to 63% with 2hr 46mins SOT and screen off 5hr 12mins. I feel like everyone elses SOT and total time is much better

I wiped the system cache and nothing changed.

I have the same issue—extreme battery drain.

I charge my phone using the original Samsung charger, unplug it at 10:00 PM, and by 6:00 AM, the battery drops to 80%.

After using WhatsApp for just one hour, the battery decreases to 21%.

With light to moderate usage of WhatsApp, Twitter, and Reddit, the battery completely drains within 5 hours and 20 minutes to 6 hours.

I visited an official Samsung service center, and they disabled most of the phone’s features, including syncing, and put most apps in Deep Sleep mode, essentially turning my phone into a Nokia 3110. However, the issue remains unresolved.

I’ve been using the device for about a month, and I have to charge it three times a day, or else I’d have to switch back to my old phone.

I also tried disabling RAM Plus, but unfortunately, it didn’t help.

Sometimes, my phone heats up significantly, even when I’ve only used it for a few minutes.

I also noticed something strange:

When I check my phone’s battery settings, it shows:
"A full charge will last about 10h"

I asked a friend who owns an S24 Ultra, and his phone displays:
"A full charge will last about 1d 1h"

Another friend with an S25 Plus sees:
"A full charge will last about 2d 2h"

What’s the solution?

I have the same problem 

I have s25 ultra since the 3rd of Feb 

The battery is good during the morning 

But at night during sleeping it drains by about 4% per hour even when I activate the ultra savings mode 

When my mobile is less than 30% before sleep I wake up i find the battery fully drained and the mobile is turned off 

Any help ?!

I performed a factory reset on my S25 Ultra, and the battery consumption has significantly improved.

Day 1 after performing a factory reset on my S25 Ultra:

Since unplugging the phone from the charger, it has been 17 hours and 26 minutes , and the current battery level is 14%—meaning 86% was used in 17 hours of phone usage.

Day 2 after performing a factory reset on my S25 Ultra:

Since unplugging the phone from the charger, it has been 1 day, and the current battery level is 25%—meaning 75% was used in 24 hours of phone usage.

Previously, my phone's battery would drain to 0% in less than 6 hours.

Note:

You can back up all your phone's contents to Samsung Cloud, so you won’t lose anything.

I disabled background activity for apps I don’t use frequently. Now, an app only runs when I open it, which helps save battery.

Hello thanks for the information. How much sot are you getting now that you factory reset. When you factory reset what did you use from the back up and from where? 

[Hussain 11]

I used Samsung Cloud to back up my device. You can create a backup without any data size limit, and Samsung also gives you 30 days to restore the backup—all for free.
