I am curious if anyone is aware of if the battery life on Apple hardware degrades over time from other hardware components? I had my Mid 2015" 15" Battery replaced as part of the recall.

I did it as my battery was only lasting 3 hours, however after getting the battery replaced the battery is lasting the exact same length of time.

I have tried doing recalibration tips, I am thinking it is either the OS is a battery hog compared to the OS we had in 2015 or something else has degraded.

Heat wise it operates quite well and the fans aren't going all the time, I tried SMC reset and PRAM but still the same.
