I've had Sunwoda in most of my iPhones. My 14 Pro Max is at 103% health. <shrug>.Everyone comes up with the same reasons for battery degradation. But how about cheapening of the manufacturing to save some bucks and was reported on last year. What about the manufacturer. We were doing that in another thread. I’m Desay and still at 100% one week after launch day and manufactured in August.
One thing for sure, I hope all this commotion about battery life encourages Apple to put a bit more health/longevity/juice in these batteries going forward.
