Yes, I know about that. The problem is that, while commuting by train to go to the office, I use the phone a little bit too much (plus, there's a part of the rail line where there isn't any signal and apparently this too drains the battery). I just feel like my old OnePlus Nord or even my Pixel 3a had a better battery life under these conditions, but then again, it's two different systems with different apps. For example: I used Boost for Reddit on my Android, I used Apollo on this iPhone. Probably the latter drained more battery than the other. I just don't remember coming home from work with 25% of battery left.
