Apple confirm that iPhones with older batteries are slowed down intentionally to avoid sudden shutdowns etc.

“Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, 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 down 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.”

I had to spend 1500Rs just because of this.

My battery was dying but I was surprised how rapidly its capacity reduced within1 month.

And then it was shutting down every 30mins and phone was becoming slow too.

Ofcourse my battery needed replacement but I could have delayed it by 2-3 months.
