How much power is left in the iPhone's battery? This is obviously a concern for many fruit powders. My own iPhone has been in use for three or four years and the battery health has dropped to 89%. On this level, I have long been indifferent. After all, cell phones are consumables.
However, quite a few Apple users are still very concerned. The decline in battery health means that the power consumption will be faster, and the battery life experience of the mobile phone will be greatly reduced. In addition, some friends are also used to dealing with their old equipment on second-hand platforms such as Xianyu. At this point, higher battery health generally leads to higher valuations.
Can't just change the battery?
Let's not talk about the impact of changing the battery on the airtightness of the iPhone. Even if the official original battery is replaced, it is considered to be disassembled. What's more, some friends may also replace non-original batteries, which will be discounted.
So after thinking about it, try to slow down the decline in battery health.Due to the characteristics of lithium batteries, we have no way to ensure that the battery health will not decline completely during use, butWe can slow down the decline of battery health as much as possible through good charging habits. If you want to "stop loss in time", you only need to do the following four steps.
1Do not charge before shutting down,do it anytime
According to Apple's official statement, the core factor affecting iPhone battery life is "the chemical age of the battery." Calculated, a cycle refers to a cycle from 0 to 100%, that is, the number of charge and discharge cycles.
Apple's standard for this is:When the charge cycle reaches 500 times, the battery can maintain up to 80% of the initial capacity,If your iPhone battery health is lower than 80% during the warranty period, you can apply for a free battery replacement at Apple's official after-sales service.
It is worth mentioning that the standards given by Apple are extremely conservative. Even if we hit 500 cycles of normal use, the battery health doesn't drop to 80% so quickly.
In this case, in order to delay the decline of iPhone battery health, you should try to avoid charge-discharge cycles, i.e.don't use it too often0%rechargeUsually when we have charging conditionsCharge anytimebest cell phone batteryMaintain at25%～75scopeIn between, a charge of at least about 25% should be considered.
2,Turn on the optimized battery charging function
In Apple's official documentation, there is a sentence that mentions: fast charging is convenient, and slow charging ensures battery life.
Foreign institutions have done experiments, using 5w, 18w, 20w chargers to charge the same new iPhone for two months.In the end, I found that only with 5w iphone the battery stays at 100%. Frequent use of fast charging is more likely to shorten battery life. The existence of trickle charging is still necessary.This is what it means to optimize the battery charging function.
Optimized battery charging is turned on by default on iPhone. If you don't care about battery life, you can choose to turn it off.The iPhone's charging speed will definitely increase after the shutdown, but the effect is not obvious.
This feature will intelligently learn your charging habits. If you're in the habit of charging your phone while you sleep at night, it will remember this interval. After charging to 80%, it will slow down the charging speed and prolong the charging time. , which can greatly protect battery health.
3Do not charge in hot or cold environments,Try to avoid charging while playing
The full operating temperature of lithium batteries in electronic devices such as mobile phones is 0~40 °C. When the temperature is lower than 0°C, the performance of the lithium battery will decrease, and if the temperature is higher than 35°C, the battery capacity will be lost.
In this regard, Apple officially mentioned that the best working environment for Apple devices is an ideal temperature zone between 16°C and 22°C.
In addition, Apple also emphasized: "When using the phone in a very cold environment, the use time of the phone will decrease and the battery will drain quickly, but this situation is only temporary. When the battery temperature returns to the normal operating range, its Performance also degrades. Then it's back to normal."
That is to say, we should avoid placing the iPhone in an environment where the temperature is higher than 35 degrees, and charging at this time, the iPhone may limit charging after the power reaches 80%. Charging the phone in a high temperature environment for a long time will cause irreparable damage to the battery.
In addition to environmental factors, the heat generated by the phone itself can also affect battery life. Many people are used to playing games while charging, which can easily cause the phone to overheat. Therefore, for the sake of battery health, we try to avoid charging while charging. have fun.
Not only that, but charging your iPhone wirelessly with a protective case is also prone to excessive heat generation. We can delay the decline in battery health by removing the case during wireless charging to reduce the heat to a certain extent.
4.Try to use the original Apple charger when charging.
In the news, we always see incidents of phones catching fire while charging, and most of these incidents are caused by using poor quality third-party chargers. Inferior third-party chargers lack corresponding safety mechanisms and are very much at risk of overshoot, overheating, or short circuits.
Although the original Apple charger is not necessarily the fastest charging, but it must be the safest. It has overcurrent protection, overvoltage protection, overtemperature protection, short circuit protection, and flame retardant protection of the casing. On the premise of ensuring safety, the decline in battery health is also minimized.
Is the original Apple charger good or not, but there are also two problems that have been complained about by many people for a long time. One is expensive, and the other is not durable. Its durability is mainly reflected in the material. The head of the charging cable is especially the hardest hit area. So quite a few people will choose third-party chargers for this reason.
If you have the same idea in front of the screen, then I recommend you to choose an Apple MFI certified third-party charger. They all have the same safety standards as original chargers and will not be healthy for your iPhone's battery. Causes damage, is affordable and the material is more durable.
I've also been nervous in the past when my iPhone's battery died. I check almost every day to see if it will go down again. Then I found that the iPhone's battery health didn't plummet, it dropped to 99%, 98%. It will drop after a while.
When you have the illusion of stability, it suddenly drops by 2%, 3%, and finally stays at 89% for a long time.
My mindset changed when the battery was below 90%, probably because I was "older" and now I have more of my old stuff. A mobile phone has been with me for so long, and it also carries my memories over the years.
I'm not as keen on buying new ones as I used to be. It doesn't matter if the battery is healthy or not. At the end of your life, it's not bad to lie in a drawer and ignore it.
