My home phone is a 12 pro - it's 15 months old. Many features are turned off. I don't carry it everyday. It sits on a table fully charged every morning, or a carry it in airplane mode. I unplug the charger - after 8 hours, it loses between 9 to 15 percent (that's not too bad). It's connected to wifi, no bluetooth. Now, the battery capacity is 93 percent ( its hardly used). The capacity concerns me, because the trade depends on the phone keeping a charge. I can't trade until the end of a 30 month period.
I use an iPhone 8 Plus for work. I've used it for over 50 months. Its on and off the charger everyday. It's used for email, teams, photos, internet, etc...the battery capacity is 99 percent ( is this right?).
The iPhone 8 Plus seems to have a much better battery life. With the purchase of a new phone, I expect a better quality phone - iPhone 12 pro should out perform previous versions....I'm thinking about changing brands
Batteries are essentially a commodity, and not one where Apple necessarily any better or worse quality than anyone else. They buy from first-tier suppliers, but they can't account for the randomness of battery performance.
If you're looking to trade in a phone with Apple, the battery capacity hardly matters. They don't care. Any trade in value assumes that the battery will need to be replaced, because it usually will need that.
I also wouldn't assume that the battery health is 100% accurate. It often seems to hold off and then updates where it might drop suddenly My iPhone 7 battery seems to be stuck at 92% battery health for a year, and I'm pretty sure it's lower than that. I expect it's going to update any time.
Apple's rating is for 80% after 500 complete charge-discharge cycles. Obviously that's been shoehorned into nice round numbers and can't possibly reflect an exact outcome. Some will do better and some will do worse, which is common with almost any item that wears.
