need help with iphone and lab top
my iphone does let me do softward update and battery does not last
What iPhone are you trying to update? If it's an iPhone 5 or below, you will not be able to install iOS 11 or later onto your device. If it is an iPhone 5s then you will be able to install iOS 11.3 but will not have the BETA battery health option. What iOS is currently on your device if it is an iPhone 6 or above?
Hope this helps
