For iPhone 6 and later, iOS 11.3 and later add new features to show battery health and recommend if a battery needs to be replaced. These can be found in Settings > Battery > Battery Health.

All rechargeable batteries are consumables and have a limited lifespan—eventually their capacity and performance decline such that they need to be replaced. As batteries age you will be experiencing more noticeable battery and performance issues. A new replacement battery completely changes your experience.
