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.
It takes approximately 2 years to go from 100% to 80% capacity.
