Apple will give you a new iPhone battery even if yours is working perfectly

"Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, [when they] have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components."

"Last year, we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting during these conditions."

"We’ve now extended that feature to iPhone 7 with iOS 11.2 and plan to add support for other products in the future."

"Our goal is to deliver the best experience for customers.""
