Since iOS 1 1 added the battery health function for the first time, people will ask from time to time why the battery health of iPhone has declined rapidly in just a few months. Is my battery normal? There are many questions about battery health, and some people will even start to question the health of iOS batteries. In fact, there are many reasons that affect the health of the iPhone battery, depending on the user's habits, which does not mean that everyone's battery health value will be the same. This article will tell you a correct understanding of the health of the iPhone battery.
IPhone battery is a consumable, so don't think that it will never age, just like batteries or batteries in electric cars or cars, it won't 100% never age or decay forever.
If the following conditions are found on the iPhone, it means that the battery health of the iPhone has been seriously attenuated, and it is time to replace the battery!
Abnormal power consumption: from one charge every day to two charges and three charges.
The battery charge is inaccurate: 98% is displayed at one time, and 78% is suddenly displayed after shutdown.
Battery expansion: if it is used for more than two years, the battery will eventually expand if it is not replaced.
Automatic shutdown often occurs: the power has not been used up, and it is easy to automatically shut down or suddenly restart.
Obvious jam: I suddenly feel that Kaka's operation is not smooth
How to check the health status of iPhone battery?
Apple is worried that the aging of iPhone battery will affect the processing performance. Since iOS 1 1, the battery health function has been added, which can be set through iOS >; "battery" > "battery health" inquired about the current battery health data of iPhone. As for how low the battery health is, how low the battery should be replaced?
Apple officially set the health status of the iPhone battery to the maximum charge, such as less than 80% or the battery cycle times more than 500 times. As long as one of them meets the requirements, the battery should be replaced. If it is still within the one-year warranty period, you can replace the battery for free. After the warranty period, you need to pay for battery maintenance.
As for the current iOS, there is no way to check the number of battery cycles, but you can still check it through AISI or iBackupBot tools.
In addition, it should be reminded that the "optimize battery charging" function in the battery must be turned on, which is a battery protection function designed for users who are used to charging the iPhone all night;
Why is the health of iPhone battery declining so fast? How to judge whether there is aging?
Many people are concerned about the problem that the health of iPhone battery is declining rapidly, which is different from everyone's habit. Now you see how others can keep the battery 100% healthy after using it for several months, and how it didn't take long for you to drop it. You begin to doubt your life and think that there is something wrong with the iPhone battery in your hand. You anxiously start asking about the health of the battery.
I can tell you directly here, but I don't need to ask others, because the final answer will be:
Batteries are consumables, and everyone's usage habits are different, so the consumption speed of relative battery health will be different.
As for the health of the iPhone battery, even if the data is maintained at 100%, it is only a reference. In fact, after more than two years of use, it almost needs to be replaced. If you buy a second-hand iPhone, be careful. Even if the health of the battery is not less than 80%, the number of battery cycles almost exceeds 500, so we can't just think that the battery has aged.
There are even users who think that it is too expensive to change the iPhone battery, and they will not change the battery for several years. Just looking at the health of the battery, they think there is nothing wrong with the battery, which leads to serious power consumption. There are also many problems directly attributed to iOS.
The easy loss of battery health is also related to the use and peripheral accessories, such as the following reasons:
Keep charging the battery until the battery is less than 20% or dead (permanently damaging the battery and turning on the low power consumption mode is invalid).
Often playing games, videos or talking while charging, resulting in the battery burning out and still continuing to use.
Use non-original or non-MFi certified products to charge.
Often in a state of high temperature and low power, it is very easy to make the health of the battery drop rapidly. Even some users like to buy wires or charging heads that claim to be original wires at low prices, especially like to see some non-MFi certified wires such as never-disconnecting wires and fast-charging wires, which are easy to cause equipment damage.
