Is there any reason why Apple still clings to the "non-removable" battery concept while nearly every other phone allows user access to the battery?
Prolonging the life of the phone? Being able to give it to your kid when you upgrade? Not having to be forced to buy a new phone because the battery is dying?
By making the battery non-replaceable, makes the phone smaller & thinner.
Considering the batteries that Apple uses can be recharged 1000 times often outlast the lifetime of the phone as the typical consumer replaces it with a newer model every 2-4 years. With normal usage a battery will last 5 years.
I've seen many times where the cover on the removable battery inadvertently fails off, as well as the battery itself.
