After 10 years of using a smartphone, the charging posture is wrong

After Tony started his daily surfing, he accidentally saw a familiar topic on the trending search. Is it not recommended to recharge the phone after running out of battery? Do you remember when you first went to college, there would be similar popular science pinch?

Zhiding Weibo said a lot of things,For example, be careful not to charge when the battery is exhausted, there is no need to fully charge it every time, and pay attention to the ambient temperature when charging.

After thinking about it carefully, Tony usually charges more casually. At the company, he has been left on the wireless charger. If he is at home, he will connect to the wired charging for a while when he runs out of power. There is no fixed rule.

In fact, this is not good for the battery. If you do this often, although the phone will not explode for you to see, it may shrink quietly. The phone that can be charged once a day will burp in the last half of the day.

So, what is the right way to charge your phone? >/ The correct, pertinent, and objective charging posture is the question of whether to charge the phone after the battery is exhausted.

In Tony’s view, friends who are accustomed to recharging the battery after running out of battery power have probably experienced the era of feature phones.This is mainly because at that time the mobile phone was not equipped with a lithium battery, but a nickel-cadmium battery.

The battery of this material is good in everything, but the shortcoming of the memory effect is really unbearable. If it cannot be fully discharged and charged, the battery capacity will become smaller and smaller over time, and eventually it will become less and less durable.

So at that time, people generally used the battery to charge when it was completely dead. But putting this habit on the more advanced and environmentally friendly lithium batteries is not a good thing.

Compared with nickel-cadmium batteries, although lithium batteries have no memory effect,But if it has been consumed to less than 10% or even 0% to recharge, it will cause excessive discharge.At this time, the lithium ions inside the battery will be excessively embedded in the lattice, and the process is irreversible, which will ultimately affect the battery life.

Conversely, if the phone is left plugged into the charger for a long time after charging to 100%, it is overcharging. At this time, the lithium ions inside the battery will be excessively deintercalated, causing the lattice to collapse, which will also affect the battery life.

Fortunately, after years of polishing, mobile phone manufacturers have put a “power management” protective lock on the battery. When the phone is automatically shut down due to low power, it will retain the last bit of power, and when the phone is charged to 100%, it will stop charging or automatically switch to low current mode to avoid overcharging and overdischarging.

However, even if there are manufacturers to help with the bottom line, frequent overcharging and overdischarging will still affect the life of the battery. As in the topic, it is not recommended to do this frequently.

In addition, whether the mobile phone can be played while charging is also an old question. Almost all friends who love to play mobile games have encountered a problem. After playing a few games, the mobile phone has issued a low battery prompt of “less than 10% battery”. How to do? Just play and charge.

But in the process of charging while playing, the temperature of the fuselage will rise rapidly. Generally speaking, the best working temperature of lithium batteries is -25~45 ° C. These days, you can take a mobile phone with a Snapdragon flagship, and you can dry the phone to about 40 degrees without charging it. Electricity, accidentally overheated.

If the temperature of the mobile phone exceeds the recommended operating temperature of the lithium battery for a long time, it will also accelerate the battery consumption and affect the battery life.

Therefore, it is recommended that friends who often play while charging buy a heat dissipation back clip, which is good for mobile phones and hands. However, playing games may also bring a DEBUFF to the battery, that is, the battery is used more severely than daily use.

You must know that the battery status of a lithium battery is also related to the number of cycles of its battery. If you play games frequently, the number of cycles will be much higher than that in daily use. Of course, the battery health will not be much better. >/ Battery not durable?

Don’t be afraid that Tony dares to pat his chest and promise that as long as you learn the correct charging postures mentioned earlier, you can delay the aging of the mobile phone battery to the greatest extent, so that it can last for a longer period of time.

Now some manufacturers have built-in the function of checking the battery status in the mobile phone: if you are using an iPhone,Open the system settings > battery > battery health page, where the maximum capacity is the current health of the phone battery, if it is lower than 80%, it means that you should at least replace the battery;

If you are using a Xiaomi phone, open the system settings > power saving and battery > battery page, where the battery status corresponds to the current battery health, if it shows “normal”, the battery also needs to be replaced;

If you are using a Huawei mobile phone, open Settings > Battery > More battery settings page, like Apple, the maximum capacity corresponds to the battery health, and it needs to be replaced if it is lower than 80%;

It should be noted that the above method is only applicable to some new mobile phones of these three brands, and older models may not support it, and other brands have not built this function, and can only use third-party software to monitor and estimate.

Tony recommends an Android app called “AccuBattery” here, which can get a relatively accurate battery capacity by monitoring the voltage and current of multiple charges and discharges. For those who want to check the health of the mobile phone battery, you can go to Kuan and other app markets to download.

Having said so much, everyone will definitely be curious, how much impact will the different charging methods have on the battery life and battery life of the mobile phone?

Coincidentally, there happened to be three colleagues in the office who bought the same iPhone 12 mini in the same year and the same month. Everyone has different usage habits: Colleague A likes to play King of Glory, but not playing while charging. The current battery health 80%;

Colleague B often plays Genshin Impact, often playing while charging, and the battery health is also 80%;

Colleague C rarely plays games and spends most of the time on the wireless charging pad, with a battery health of 88%.

The charging habits of their mobile phones are very different. After more than a year, everyone’s battery health has also changed a lot. The situation is similar for the two colleagues next door who use Xiaomi Mi 11 Pro. One of them plugs in the video game Genshin every day, and now the battery condition is only normal.

The other doesn’t play games, but as long as the person is in the office, the phone is on the wireless charging pad and the battery life is still good.

So you’re saying that the habit of using batteries has an impact on battery life? There must be. But Tony still feels that there is no need to deliberately change his habits of using mobile phones for battery life.

After all, it is not too expensive to replace the battery of the mobile phone these days (the iPhone is not included here). Besides, many times when the battery can’t hold it, it’s almost time to change the phone.

So, there is no need to kidnap yourself because of this. On how to charge the mobile phone, Tony’s suggestion is: how to be comfortable, if you can protect the battery smoothly, then it is the best. There’s no need to trouble yourself with this kind of thing, you say?
