I think the S21 Ultra has one of the best battery life of any S series phone. My S23 Ultra edges out over it now, but then again, my S21 Ultra is 2 years older. The camera is a night and day fifference to me, even moreso in low light. If you compare 108MP to 200MP, the gap widens even further, again even more in low light. I guess everyone's experience is different, but I do agree in purely a day to day use, I can't say there's a huge difference, but that's because the S21 Ultra is an excellent and capable phone. Since the title of this thread says 'still rubbish" I assume you're an iPhone or other brand user, or simply hate phones altogether.
