Free bump to @Mainak777This. IMO, battery life should be one of the top priorities when people buy phones. Sure, S22U (and many more Android phones) offers plethora of customizations and functionalities that iPhones might not have, but until Samsung gets it right with a better battery life, I am team Apple.
I can trust iPhone 13PM (at 25% battery life) to last for a few hours when I go out and don't get the time to charge. Can't say the same for S22U
This is definitely not the case. I have a 14month old Exynos Note 20, Note9 also exynos, A52s (SD) and Multiple Tab Ss, an iPad, and iPhone XR and don't find any difference in terms of reliability.
I regularly and happily go out with 30% charge on my Note 20 and A52s knowing fully well how long they are going to last.
