Hi guys! Since the old battery in my iPhone 6 got too sensible to cold climates (it would go from 50% to dead within minutes if exposed to temps below 60 F), I replaced it myself with an original Apple one. Everything was perfect, Coconut battery gave me stable 98-99% battery health. Then I had to use a navigation app and connected the phone to the car charger (which, by the way, was not even able to charge the battery: using the navigation app, the battery just didn't discharge). Since that moment, my battery health fell to 75-80% (I had around 10 charge cycles on it back then). I now have about 45 cycles, tried every trick in the book, but it just stays there. Did I really ruin a new battery using a car charger?
