|Hello I'm your DER (Deer) a house that loves digital, likes to talk about current affairs, and digs out cost-effective things.
Recently, a friend sent a private message to DER, asking how much difference there is between 80% and 100% battery health.
I have to say that every time I mention the health of the mobile phone battery, many friends always want to use the battery health to 80% during the warranty period, so that they can replace the new battery for free, so that 80% has become a "standard" for the health of the mobile phone battery, and at the same time, I am curious about how much difference it is from 100%?
Since Apple launched the "Battery Health View", the vast majority of mobile phones can now see the percentage of the current mobile phone's battery health in the Settings - Battery column, that is, the label of the current maximum battery capacity.
As a result, some friends feel that when the percentage of "battery health" is 100, the battery power of the mobile phone will be very durable, and they will basically go out with a full charge, and there will be left after returning home; Once the "battery health" percentage is close to 80, you will feel that the battery level of your phone will drop quickly, and even bottom out in less than a day after going out on a full charge, which will cause battery life anxiety.
Of course, some friends believe that the so-called battery health is not accurate, because the "physique" of each battery is different, some have a relatively large capacity, some are small, and the battery health is only the manufacturer according to the current state of battery discharge, to estimate the loss of the battery, not the maximum capacity of the current battery.
Even if the health of your mobile phone's battery drops to about 80%, as long as it is not the problem that the mobile phone itself consumes too much power, most of the mobile phone batteries are wearing and tearing normally, and the health will be reduced, but it will not "pull the crotch". Unless, we often play while charging, the mobile phone battery is often charged and discharged when it is hot, even if the health of the mobile phone battery is 90%, the actual battery capacity has long been decayed and "not durable".
Therefore, the so-called "battery health" does not really reflect the health of my phone's battery, let alone a cold 80% number, as the standard for us to replace the battery, but should be judged according to our actual use experience.
What is certain, however, is that when the battery health of Apple's iPhone is below 80%, or when we don't feel durable, the phone is noticeably less silky and smooth. No kidding, this once made many friends think that it was not Cook's "remote spellcasting" planned scrapping, and wanted us to change to a new machine.
In fact, this is just Apple's "careful thinking" to protect the health of the battery. Apple's iPhone battery is inherently small, and in order to show Apple's "God optimization" as much as possible to ensure battery life, the only way to reduce the core frequency of the processor and reduce power consumption is naturally not so strong. In addition, when the mobile phone battery is less than 20% or 10%, the mobile phones of various brands will obviously become stuck, which is a self-protection measure to save power, so the mobile phone stuck is not necessarily a healthy pot for the mobile phone battery.
If you want the phone to return to its previous smoothness, you can only replace the battery, but I didn't expect that 80% of the battery health has become a "feng shui" in the performance of the phone.
Since there is such a big difference between 80% and 100% of mobile phone battery health, how can we protect the battery in our daily life?
Der thinks that the most important thing is to avoid overheating when charging and discharging.
Because too high a temperature is the root cause of the loss of lithium batteries. Like when charging, I don't know if some chargers are cutting corners or design problems, charging the iPhone 15 Pro Max of Der until it is hot, but I haven't encountered this situation with the original one, so it is not recommended that you save this money on the charger, and the worst is to choose the charger of big brands such as Baseus and Olympian to ensure it.
Then when you use it, avoid playing while charging, which is the most likely behavior that causes the phone to heat up and lose the battery. Anyway, now that Android fast charging is so fast, it takes less than 20 minutes to charge to more than 80%, and you can continue to use it.
If it is Apple's iPhone and Samsung's fast charging that "does not grow in 10,000 years", the time is a little longer, but the loss of the battery is also low, isn't it?
Finally, in the face of mobile phones has become an indispensable part of our daily life, especially in the current environment, the pace of life is accelerating, the frequency of everyone using mobile phones is becoming more and more severe, and it is only a matter of time before the battery health drops to 80%. Compared with 100% battery health, it increases our range anxiety at least and affects our daily use experience, which is still quite a big difference.
