With an update it made in the past years, Apple added a feature where users can check the battery status of their iPhone. With the addition of this feature, users keep in mind “What is the battery health, will the situation be dangerous for the device?” Questions like these started to stick around.
While some iPhone users use their batteries consciously and change them regularly, there is also a section that uses it carelessly. Let’s examine together how healthy it is to use the device with a bad battery and when to change it.
First, let’s look at how you can check your iPhone battery health.
If you have iOS 11.3 or later; If you’re using an iPhone 6 or later, you can check your battery capacity by going to Settings > Battery > Battery Health.
In addition to the capacity of your battery, there is another important metric to look at. In this measurement, if your battery is in good condition and offers the highest performance for your device, it says “Highest Performance Adequacy”. In addition, a “Service” warning is now displayed on batteries that have lost power and are performing poorly.
Let’s talk about the lithium-ion batteries used in iPhones.
Lithium-ion batteries are preferred by Apple and other smartphone companies. While these batteries offer faster charging compared to older generation batteries, they also make the battery last longer. This results in a battery that has both small dimensions and offers the best performance for the device.
The lithium-ion batteries used in iPhones are first charged by the device to 80 percent, and then the remaining 20 percent is charged slowly to protect the battery.
Phone batteries also age chemically.
Like all rechargeable batteries, iPhone batteries age chemically. As the components in batteries age, their effects diminish. This, in turn, causes the device to hold less charge and discharge faster. In addition, the impedance of an old battery rises.
The impedance in the battery affects the instantaneous power transmission. A battery with a high impedance means a battery that cannot supply the system with the power it needs. In other words, to summarize briefly, an old and high impedance battery cannot provide high performance to the iPhone.
Let’s come to our main topic: When should the iPhone battery be replaced?
Apple considers any iPhone with a battery capacity of 80% or more to be in optimal battery condition. When the battery level drops below 80%, the device gives a ‘Service’ warning. When you receive a service warning, you need to take your device to Apple Official Service and replace your battery. As we mentioned above; an old battery cannot provide maximum power to the device. This can cause stuttering, unexpected shutdowns and not holding a charge.
How can you extend your iPhone’s battery life?
First of all, don’t worry too much about your iPhone’s battery life. These batteries are designed to last a long time and provide maximum performance. If you use your device consciously, you will get more efficiency from your battery.
To use your iPhone’s battery longer; Use the latest iOS version, protect your phone from high and low temperatures, avoid high temperatures during charging, keep auto-brightness on.
So what’s your battery health percentage?
