Uh, your power issue is likely a power issue. How are you delivering power to the SD card? It should have a power line directly from the 3v3 rail to VDD, with at least 1uF capacitor close to the power entrance. Put a multimeter on the 3v3 rail while the battery is connected and make sure it is right at 3.3. Batteries are generally able to deliver the necessary current, but may have voltage sags, so you need to make sure you have adequate capacitance on the power line.
Test with the SDMMC_Test.ino

Got fixed. For some reason, commenting out
while (!Serial) {
delay(10);
}
fixed the issue. This is interesting as I had used the same code with previous ESP models and it never created any issue but with S3 it was the issue. It does work but I am not sure why this was the issue.

Hello @raprakashvi, it really looks like a power issue. I will close this issue, if needed you can reopen it.
