I’m considering buying an iPhone 11 Pro Max. I’ve owned my current flip phone for about 10 years now and will probably hold on to a new phone for a long time also. So battery replacement is a concern to me. I’m getting contradictory information from store clerks regarding this phone’s battery. There is no separate battery compartment on the phone; the battery is located inside the phone. Some store clerks say the battery is replaceable when the battery dies but Apple has to do it. Other store clerks say the battery is not replaceable when the battery dies and the phone will have to be replaced. What’s the straight dope on this phone’s battery situation? Can the battery be replaced on this model or not?
