Anyone to comment on the Note 20 5G battery life. I moved from A12 & A72 and I never had to charge my phone during the say even with music + hotspot; but with a Note 20 i have to charge twice !!!

Hi;  Was wondering if anyone could assist. I'm using an A72 Android 12 and i cant seem to be able to change my CSC. I am in South Africa and would like to change to XFE or XFA but it defaults to XSG when i flash those XFA roms.
