Avoid extreme ambient temperatures. Charging the device in high ambient temperatures can damage it further. Software may limit charging above 80% when the recommended battery temperatures are exceeded. Even storing a battery in a hot environment can damage it irreversibly.
Because battery degradation varies, users may actually find that their iPhone's battery capacity does indeed degrade after using a Smart Battery Case. But that doesn't mean it's the Smart Battery Case that's causing it. Correlation doesn't equal causation. All lithium-ion batteries will degrade normally over time.
If your phone's battery health is at 79% or less, it has been significantly degraded. At this point, you should probably take your iPhone to an Apple Authorized Service Provider for replacement.
One action that can lead to lower battery health is high heat. Heat is a battery's enemy. Cold is no friend to batteries either, resulting in a shorter use time, but that is only temporary until your battery warms back up again. Apple says your iPhone can safely run in temperatures of up to 95 degrees Fahrenheit.
Turn on auto-brightness. The brightest screen settings tend to drain your battery quickly, which forces you to go through charge cycles quickly and lose battery health. Check your background activity in Settings > General > Background Refresh. Too many apps running in the background will drain your battery.

Yes, it is completely normal for your iPhone 12 Pro to have a battery health of 90% after a year. Batteries degrade over time. There is nothing you can do about that. In the case of iPhones, Apple says an iPhone's battery health will be about 80% after 500 charging cycles.
The Battery Health screen includes information on maximum battery capacity and peak performance capability. Maximum battery capacity measures the device battery capacity relative to when it was new.
Understanding iPhone Battery Capacity Your phone's maximum battery capacity goes down over time. New iPhones typically come with a 100% capacity, but charge cycles and potential damage (like exposing your phone to extreme temperatures) reduce the capacity.
When the liquid inside the battery freezes, it can break the electrical connections inside and bend the plates. This lowers the battery's output, often far enough that the battery is useless.
Don't let your Smart Battery Case overheat. But, on the other end of the spectrum, a Smart Battery Case could theoretically cause battery damage — but not for the reasons that you think. It comes down to overheating, which definitely can damage a battery and reduce its overall capacity faster than normal.
As we've said earlier, extreme temperatures are the biggest enemies of mobile phone batteries. To keep your battery in tip-top shape for longer, you should avoid exposing it to extreme heat or cold.
They automatically switch to a safe float voltage level that keeps the battery charged and yet does not do any harm to the battery. In fact, in most cases, this type of charge maintenance will extend the battery's useful life by at least 50%.
The problem is, the battery status report is apparently not accurate. Adrian Kingsley-Hughes of ZDNet did the test on his iPhone 13 Pro Max. After owning the device for 104 days, the device's Battery Cycle Count data reports that it has been through 92 recharge cycles.
