I purchased a third party battery for my iPhone 6S Plus before the update that has affected the battery app from working properly or giving a warning. My question is, is my iPhone 6S Plus affected by this update, and if it is, is there a workaround, or should I just purchase a battery from Apple? I’ve always been one to do things right the first time, or just buy the best the first time, but with this phone being so old, I thought…maybe I should buy third party, and here I am:), back to why I have my philosophy, lol.
Battery percentage should be available irrespectively. Other data reported depends on battery logic, thus on supplier. If that’s important for you it would be advisable to ask for confirmation before purchase, whatever iOs version you’re using. It doesn’t seem iOs 13 triggered any additional malfunctioning/scary warning as far as I know, except on latest models relying on batteries including the Texas Instr. IC.
