All smartphones, including iPhones, must have replaceable batteries by 2027 in the EU::undefined
I’d much rather just have a bigger battery. Replacement is more useful for longevity for me.
You’re not going to get a bigger battery though. Battery size is a pretty much maxed out, the only way to make a battery bigger would be to make the battery physically bigger. This would make the phone bigger / heavier. So it’s not going to happen.
If you are waiting on some magic new battery chemistry it’ll come along eventually but you’ll be waiting a while, and stubbornly not having a replaceable battery in the meantime isn’t going to make any difference.
