Battery health
Does battery health drop after charging an iPhone 11 Pro to an iPhone charger?
iPhone 11 Pro, iOS 16
Battery health drops for two main reasons:
- Number of full charging cycles (max about 500 on iPhones)
- Age of the battery (not of the iPhone). See this support article about that:--> iPhone Battery and Performance
Start worrying when your maximum capacity is close to 85-80%.
