S23 Ultra Very Bad Battery Life

[pranayvb]

Very disappointed with the battery life of my galaxy s23 ultra. The battery life is not even 12 hrs 😕

I charged it in the morning at around 7:30am and by evening 6:30pm down to 15%. This is very bad. Even the SOT is hardly 3-4hrs maximum. I keep AOD (during daytime only), 120hz, QHD, haptics and sound on. Bluetooth is on as it is connected to my galaxy watch 6 and location is on most of the time along with mixed use of 5G and wifi. Brightness full sometimes as I go outside during day time as I am a student. BTW mine is on performance battery profile.

The screen off time is not even accurate ….

Attaching the screenshots below.

Hello @pranayvb and may I extend a Warm Welcome to the Samsung Community Forum Section for Uk  / Eu Members. 

Personally as long as my phone allows me a full day's usage in-line with how my phone is set up , the apps I have chosen to use ,and my usage habits then that's a good indicator for me. 

I attain a full day's usage with the Samsung Galaxy s²³ Ultra and s²⁴ Ultra. 

Perhaps try >

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

Sleep and Deep sleep for some apps that use more apps. 

Google Chrome for me uses way too much resources hence why I choose to use Samsung Internet. 

I also see you use 5G which is a known battery resource drain. 

If i can be of any further help please don't hesitate to ask  😎

Can I ask what software version you have installed.

The reason I ask is that you mention you have 'performance' mode.

In oneUI6 update at the end of 2023 this changed to only two options 'standard' and 'light'.

If you can check the software you use and ensure you have updated to oneUI6.1.

It may be you still have an earlier software version installed.

I assume you use the phone from the region you live ? I.e an Indian variant in India... or a UK variant in UK ?

Hey!

Yup already did that wipe cache partition and all. Lot of apps are in sleeping and deep sleeping too. I just don't get 1 full day batting right. Its hardly 12hrs 😞

Hi Smiley,

It's on the latest version onui6.1 and currently waiting for 6.1.1

My bad it's actually the light performance profile. Its just that my device hardy gives 12hrs of back up i expected more like atleat 24hrs. But its not the case ....

I find my S23u fine on battery as so many others do. So it is strange your experience is a lot worse.

Hopefully a future update will help resolve.

You could also consider setting up some routines to try and help.

I had problems with my battery... I checked the battery settings and found the fast charging had toggled off at the original 6.1 update. It could be something as simple as that. 🤔
