I think you have to take things like that with a very big grain of sand with way to many variables in it. how many apps you have running, how much you use your phone if you game on it. listen to music. how many emails and notifications you receive, how you actually condition the battery, all play a factor, As many people say no two people are the same, thus how each person uses their phones will be different. And not being funny some people might be happy with short battery life. I myself am always near somewhere to charge my phone. and with how fast they charge now it's not really a problem(for me anyhow) Whilst the battery life on my old Samsung galaxy s21 ultra(uk 512gb) was not the best i still managed with it perfectly. i will say this though.; the battery life is far far better on my new Samsung galaxy s21 ultra (uk 512gb). but that is ofc my usage patterns and the battery is phone is still learning.
