After updating to iOS 16, the iPhone battery drains very fast.

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.

• iPhone Battery and Performance.
• Maximizing Battery Life.
• About battery usage.
• Check the iPhone battery health and usage.
• Optimized Battery Charging.
• Use Low Power Mode.

Check the millions of posts on the internet complaining about battery drain on IOS 16 … this is a wide spread problem and provides evidence that Apple has not conducted proper QA before releasing the OS to the public, which is a shame and reflects badly on them.
