iPhone 15 showing battery as not genuine (i never changed it) and keeps crashing
Hello
i‘ve had my iPhone 15 for 8 months now and since a week i was getting the following problems. My phone sometimes just turns completely off even tho i have battery, sometimes it shows my battery percentage as 0% even though it has 80% and it still turns off in addition to that is my phone sometimes not showing my real battery health it just says 0% maximum capacity and charging cycles are 0. And the battery is also detected as non genuine even tho i haven’t changed it and i got the phone sealed. Normally it’s meant to show 94% battery health and 360 charging cycles. Please help me i already downgraded from the beta to standard ios and it still doesn’t work.
iPhone 15 Pro, iOS 18
