The recent online "do not recommend charging your phone after running out of power" topic has aroused heated debate, almost every day essential charging session, there are really so much to say?
Times have changed, charging without running out of power
In the era of feature phones, it was common sense for many people to run out of power before charging. This is mainly because most of the batteries used at the time are nickel-cadmium batteries, if not completely exhausted for a long time before charging, the "memory effect" of this battery will lead to lower and lower battery capacity, accelerating battery aging.
But now the phone battery has been completely different, smart phones are basically switched to lithium-ion batteries. This more advanced battery does not have a "memory effect", even if the power is not exhausted and then recharged, there will be no impact on the battery capacity, so no longer need to exhaust the power and then recharge.
The outdated "run out and recharge" theory happens to be the Achilles' heel of lithium-ion batteries. Lithium-ion batteries have the disadvantage of not being able to withstand over-discharge. When a battery is over-discharged, excess lithium ions are held in the lattice, causing irreversible damage and affecting battery life.
However, you don't have to worry too much about normal use, cell phone manufacturers have long thought of this problem. The phone power management system will have over-discharge protection, even if you use the phone automatically shut down, the phone still retains a certain amount of power, not to over-discharge direct damage to the battery.
Sometimes we are used to charging our phones plugged in before going to bed and not unplugging them until the next morning, which is a bad habit, but cell phone manufacturers still do optimization for this scenario. For example, when charging to 80% power at night, the phone will charge in trickle mode or pause charging until the morning to 100% power. After a full charge, the phone also supports automatic stop charging to reduce the impact of charging all the time on battery life.
These habits are more friendly to the battery
Although the phone power management has appropriate protection measures for over-discharge or over-charge situations, but we still have some tips to extend the battery life in daily use.
The manufacturer also has appropriate reminders, such as to try to keep the power between 20% and 80%, can keep the battery in better condition, thus extending the battery life.
So in order to keep the battery in the best condition, we should not wait until the phone is automatically turned off and then charged, but usually free to plug in and charge, try not to let the power below 20%. At the same time, it is best to control the power within 80%, and do not keep plugging in the phone to charge.
This time there is also a misconception worthy of attention, some friends may think that too frequent charging of the phone is also bad, will accelerate the battery aging. But the battery cycle is calculated by the amount of discharge, the phone discharged to 100% of a charging cycle, and does not mean that every plug charged even once a cycle. Therefore, the usual fragmented time free to plug in the charge on the line, do not worry about the number of times to charge. On the contrary, if you can usually keep the power in the best condition, but also help to extend the battery life.
The Apple battery page introduction also mentions that when storing the device for a long time, do not fully charge or fully discharge it, indicating that both are bad for the battery, and it is recommended to keep the power at 50%.
In addition, to have a better battery life, you need to keep your phone at the right ambient temperature. In the battery introduction page on Apple's official website, the best temperature for iPhone phone operation is between 0 and 35 degrees. Try to avoid charging the device in an environment that exceeds 35 degrees, and charging in a high-temperature environment may damage the battery capacity.
Charging while playing is also the way many people are accustomed to using, but in fact this charging method also has an impact on battery life. When playing games, high performance release will generate a lot of heat, resulting in the body temperature rises. And charging will also heat up, the battery is easily in a high temperature state, high temperature charging of the battery will affect the battery life, so it is best to avoid charging while using as much as possible.
Some gaming phones are specially optimized for charging while playing scenarios, for example, they will provide charging separation mode, where the charger only supplies power to the phone and does not charge the battery while playing games, avoiding charging heat and enhancing the gaming experience. Of course, if your phone does not have charging separation mode and you want to charge while playing, you can add a cooling back clip to offset the heat and reduce the impact of temperature on the battery.
There is also a very important habit of use, usually use the phone charging, be sure to use the original charger and charging cable, so that you can not only enjoy the fastest charging speed, but also to avoid cheap wire to battery damage or cause safety problems.
Battery health is also measured
Usually we can also learn about the battery health information, there are already many phones that can view this information in the settings.
Xiaomi / Redmi
For example, for Xiaomi/Redmi phones, you can see the current battery health information in Settings - Power Saving & Battery - Battery - Battery Status, which is divided into four grades, and when it is displayed as average, it indicates that the battery capacity has declined significantly.
Huawei phones are able to see the maximum capacity in Settings - Battery - More Battery Settings, which is displayed in the form of a percentage.
Vivo phones can see the current maximum battery capacity in Settings - Battery - More Settings - Battery Max Capacity, which is also displayed by percentage.
The iPhone can also see the maximum battery capacity in the settings of Battery - Battery Health, also in the form of a percentage display. iPhone battery maximum capacity below 80%, you can consider changing the battery.
Now the phone in the battery management has been more perfect, on a daily basis prone to problems such as over-discharging, over-charging and other scenarios have corresponding protection measures to minimize the impact of bad habits on battery life, the normal use of not too worried.
But if you really pay special attention to battery health, there are some tips on how to use it. Don't wait for the power to run out before charging, don't keep your phone plugged in to charge, avoid using it while charging, use the original charger, etc. Paying attention in these areas can extend the battery life to some extent. However, no matter how good you keep your habits, the battery health will still gradually decrease. When the battery life has become significantly worse, you can consider replacing the battery.
