Unfortunately, I took a used iPhone phone with a 100% battery, in less than a month it became 86% and now it stays like this, which is why it began to lag. Although, for my part, I treated the phone well and according to all iPhone rules, so to speak. And when I took it, there was a couple in front of me in the store and a man complained that he had already come to them 2 or 3 times with a heating problem, and for some reason they could not fix it. Apparently I shouldn't have paid proper attention to it then
I contacted this service center with the problem of charging the phone — it stopped charging. The guys quickly found the cause and fixed the malfunction. Everything is working fine now.
I applied several times for various reasons) Bought a brand new iPhone 15 pro, some accessories (like a charging wire), and also changed the battery in the old man 12 Pro Max. In time, everything is as fast as possible, what is on order and purchase, what is on replacement) Alexandra's girlfriend listened to all my wishes and requests as patiently and attentively as possible) For which I thank her very much: I would not tolerate such a stuffiness)))
