Iphone 11 important battery message
it's been a month already but that (important battery message) is still there. I tried force restart but nothing happened. I use my phone for sms/call and light social media browsing. Usually my battery would reach up to 2 days with having 30% remaing as my lowest and i charge it until it reach 100%. I just want to ask if this is normal if no then how will i fix this or end it.
iPhone 11, iOS 15
