Ang ayaw ko lang sa apple products is hindi na basta-basta ma repair unlike sa mga old gen units.
Yung latest iphone 12, if you replace battery from other iphone 12 unit, magloko na yung camera functions mo.
This is the greedy part of apple, gusto nila bibili ka ng bago kahit working pa unit mo.
Sa software lang nila ginagawan ng paraan para hihina performance unit mo.

I also observed lately lang yung iPhone XR ko, everytime mag upgrade ako to latest iOS, mag decrease talaga battery health.
Until I stopped upgrading to latest iOS, hindi nag decrease battery health at 91%.
Let's see if mag degrade talaga pero planned obsolescence talaga ginagawa ng apple ngayon.
