What is iPhone battery health?

The battery of an iPhone is a physical and consumable element. Like a car battery, the iPhone's battery wears out with use and the passage of time. The iPhone helps us know how it is so we can make one decision or another.

How does an iPhone battery work?

The iPhone's battery is lithium-ion, which is currently the most advanced technology. With a battery of this type, it is not advisable to have your iPhone at 100% or leave it at 0% for a long time.
The iPhone and its battery have a certain number of charging cycles. A charge cycle is achieved by filling the battery up to 100%. It doesn't have to be continuous. That is, you can charge the iPhone 80% at work and 20% more at home. Both charges will be one full charge cycle. In short, with a lithium battery, it is not necessary to charge your iPhone up to 100% without interrupting charging. Simply charge it whenever you want and need it.

Analyzing iPhone Battery Life and Performance Capability

All batteries have a limited life. Over the years, it is inevitable to notice changes in its performance. This is due to the aging of the battery.
Where do we find that information to know how it is? You have to go to Settings > Battery > Battery Health. Here you will find two sections:

Maximum capacity
Peak performance capacity.

The maximum capacity is followed by a percentage (95%). This refers to the wear and tear it has had. It leaves the factory at 100% and, after two years, it can be around 80%. How is this translated? Well, if before it lasted, for example, ten hours watching videos, Now after two years, it would last eight.

If your battery is already degraded to a higher level, you will see that in Peak Performance Capacity, you can activate or deactivate it. This means that your battery may sometimes find itself without enough power for some process. If you turn on Peak Performance Capability, your iPhone will limit the processor speed, so you don't experience unexpected shutdowns. It is something similar to the contracted electrical power that you have at home. If you exceed what the differential can give, the power will go out.

Avoid high temperatures: Do not charge the iPhone in the sun, or with an external battery on the street in summer, unless it is essential
Don't be afraid of short charges: It is better to carry out small charges than to take the battery to an extreme (0%) and raise it to 100% every day.
