How to Check iPhone’s Battery Health
With time, the battery of every smartphone degrades. The same goes for the iPhone’s battery. If you use a phone for a longer time, you will also feel that the battery life diminishes over time. Now the battery lasts for lesser hours than it used to be. It is because the battery eventually starts to lose its ability to hold a charge. This maximum charge capacity keeps getting down with the time and batteries become less efficient.
How to check the battery health of iPhone
Apple has added the battery health section. So, you can navigate to Settings > Battery > Battery Health to check the battery health.
Here check the maximum capacity. For a new iPhone, maximum capacity is 100% but it will start going down with the time.
You must know that Maximum battery capacity is the measure that shows battery capacity relative to when it was new. It means 100% battery health shows that your iPhone still retails the battery it used to do when it was new.
A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles if you use it under normal conditions. There is no option to check for the iPhone battery cycle count but you can check the battery health using the steps I added.
Peak Performance Capability section is also important. Apple reports the problem here if the battery is unable to deliver the power for peak performance. If battery health is not up to the mark and cannot support the normal peak performance, Apple will tell you.
In this case, the iPhone will unexpectedly shut down and will enter the performance management state that slows down the CPU dynamically to reduce the peak power demand. If you do not want to compromise with the performance, you will have to get the battery replaced.
How to maximize battery performance
Here are a few ways to improve battery performance and keep the battery healthy.
1. Enable Low Power Mode
Apple added Low Power Mode in iOS 9 that aims to extend the battery life of your iPhone. It reduces display brightness, optimizes device performance, and minimizes system animations when the battery is low.
2. Store it half-charged
When you do not want to use the iPhone, store it with a half-charged battery. Also, place your device in a cool and moisture-free environment.
3. Change charging habit
Always avoid draining your phone battery all the way to 0%. Keep the battery in between 20% to 80%.
4. Avoid extremes of heat and cold
Too much heat or too much cold, both affect the battery and shorten its lifespan. So avoid it.
5. Use Dark theme
Enable the dark theme to maximize battery performance.
