Depends on what you mean by “replaceable”. It’s quite easy to physically replace the batteries on most modern phones. The problem is actually acquiring the batteries, as well as the new batteries actually working after installation. Apple is the only one that specifically programs their devices not to work properly if you replace the components in them yourself, and refuses to sell you OEM components.
Except that many Android phones also don’t have replaceable batteries anymore.
