Not bad to be honest.
Full day battery life, that would even carry over to next day if I don't heavily use it but, that depends on network connectivity etc.
I charge inconsistently without any schedule, because some people love to "battery watch" their phone as if they're going to die if they do more than 1 cycle a day or similar. The 120W definitely is a massive help and I absolutely DO NOT have a schedule on charging lol, if it's low, I charge it. 1/10th of the battery, 5/10th of it, I don't care, long as it's above 35% I'm happy with it haha! If I charge it to 100% it's only because I'm at my desk using my PC and I let it charge enough.
Mobile network I limit to 4G as I don't really care about 5 atm, I use Wi-Fi 6 at home and at work so helps with battery life.
Nothing really wrong with the ROM apart from recently I've been having some issues with my Wi-Fi just refusing to provide connection to my phone, but mobile network working fine.
This is more than likely isolated down to an issue with my network rather than the ROM.
