Low battery warning keeps appearing multiple times
I have an iphone 11 64 gb. For half a year when my phone has 20% or less that low battery notification keeps appearing multiple times even after a say on it . It happens when my phone has less than 10 % too , i don’t know why , my battery health it’s on 86% . Does anyone know what i can do , or if someone had this problem too ?
iPhone 11, iOS 15
