Battery status bar
My iPhone battery status bar says 77% but it’s red instead of the usual green. Why?
iPhone SE, iOS 12
Hi there,
if your iPhone batter is charged more than 10%, you may consider checking the Battery Health in Settings > Battery > Battery Health to check if your battery needs to be replaced. Once your battery reaches 80% in battery health, it’s time to replace it. You can learn more about your iPhone battery here: iPhone Battery and Performance - Apple Support
I hope this helps you.
