Short battery life on iPhone 16 Pro

All rechargeable batteries are consumable components that become less effective as they chemically age.

Recent software updates can accelerate that process by adding features that consume more power.

As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged.

Apple won’t replace the battery until it reaches 80% capacity.

Li Ion (Lithium Ion) batteries have recharging capabilities; however there are limits.

I recommend to slow charge your iPhone to maximize the charge capacity, battery health and efficiency. ⚡️🔋

NOTE:

Capacity loss in standby applications is largely determined by temperature.

Charge above -30°C and discharge below 55°C for best results.
