Firstly. Make sure you're getting fast charge 2.0 not just fast charge. Makes a huge difference. Need a fast charge 2.0 cable and plug. Personally I feel my phone is charging incredible fast.
Here are my suggested actions for battery:
Go to device care, memory, and turn off RAM Plus. This massively helped my battery and system performance. This personally really helped.
In settings, you could see how you get along with changing your performance profile to light.
Since you transferred via SmartThings, I would also highly recommend this.
You could also try:
1. Turn off the device.
2. Connect to a computer using a USB-C to USB-C cable (you may also connect to another Samsung mobile via USB-C). Press and hold the Volume Up key and then press and hold the Power key.
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight "wipe cache partition."
6. Press the Power key to select. Press the Volume down key to highlight "yes," then press the Power key to select.
7. When the wipe cache partition is complete, "Reboot system now" will be highlighted.
8. Press the Power key to restart the device.
I have not personally set my performance profile to light and kept it as standard. But I was getting about 6 hours of battery before doing the steps above.
Additionally, it can take a while for the battery optimizations to fully take place.
I noticed you had the s23? Did you happen to use smartthings to move everything over? Ive noticed people mention the apps from an older phone moving over has caused them battery issues, so they factory reset device and manually installed their apps.
