Noted a significant increase in battery drainage on the Samsung S23 Ultra after the One UI 6.0 update. Prior to the update, I could reliably use my phone for a full day with moderate usage (85% to 19%), and under normal use, it would last more than a day (85% to 15%). However, following the One UI 6.0 update, the battery backup has significantly worsened. It now takes only 2 hours and 38 minutes to deplete from 85% to 64% during normal usage (last charged 4 hours and 20 minutes ago). I am attaching a screenshot for reference.
I kindly request the Samsung team to address this issue promptly and release an update to resolve the battery drainage problem. Your swift attention to this matter would be highly appreciated.
In settings, go to Battery and Device Care, tap on Battery to see what is draining your battery. You can get a idea which apps are consuming more battery.
When you experience fast battery drain in your Samsung Galaxy phone, you may need to do the following to check it and decide whether you need to replace it or not.
1 Check if you are using unapproved charger Unapproved chargers or cables can cause the battery to explode or damage the device. Any damage determined to be caused by using unapproved chargers or cables will result in the voiding of the warranty.
2 Don't use the old charger Using the old charger of the old device may provide less power from the charger to the new device. It may not charge or the charge will take a longer time.
3 Check if the charger used is compatible for your Galaxy device. Note that the different devices have different required charging current and thus it must correspond with the output of the charger charging current.
4 Close all the applications Note that while charging, we advise closing all the applications on the device and turn off the mobile data or WI-FI.
5 Use Power saving mode Power saving mode can reduce the battery consumption, by enabling Power Saving Mode in Samsung Smartphones. You can now control your mobile device's battery usage through the Power saving mode settings when the battery charge drops.
5 Use the device on the safe mode If the battery drains fast while using, we recommend using the device on the safe mode to check the problem of the device.

Note: By activating the safe mode we have just disabled the third-party application and no data have been lost. You may need to keep an eye on the device for 2-3 hours and watch the battery consumption if the issue is solved or not.
To deactivate the safe mode you may need to:
To deactivate the safe mode, you just need to restart the device.
