What are you calling a depleted battery? The same thing Apple was doing until it bit them in the rear when they were going to throttle down older iPhones before it blew up in their face and then having to save face by offering to replace batteries (but still expecting users to have to pay $29 for one which for the mAH is still grossly overpriced compared to Android replacement batteries.
Where have you been for the last three weeks? Climbing Mount Everest? Your abysmal ignorance is not my problem. I’ve posted the explanation of a chemically depleted battery many times; I’m not going to do it again for you. Go back and read one of the previous posted explanations.
Apple’s $29 is more than competitive when compared with the Samsung Galaxy Note 8 battery replacement service at $94.95. Amazon sells the OEM battery for that model
by itself for $28.00. . . And you have to do the replacement yourself. No warranty.
Just more ignorance on your part.
