Charging Your IPhone All Night Without Damaging The Battery, 4 Settings Make The Battery Last Longer

Many friends connect their mobile phones to the charger before going to bed at night, and they always feel a little uneasy in their hearts. They are worried that continuing to charge them all night will cause the battery to be damaged and cause the battery to bulge.

There are many different opinions about this on the Internet. Some people claim that they need to get up in the middle of the night to unplug the power supply. Some people emphasize that the original plug must be used. There are also various things called "battery care artifacts".

Today, we all speak the truth. We don’t do those mysterious and mysterious things, and we don’t need to download any software, let alone buy any accessories.

Use the native settings of the iPhone itself and adjust them one by one in a step-by-step manner to make them perfect. Whether you are a novice who knows nothing about digital or an elderly member of the family, you can master it easily and smoothly.

It really makes the battery last longer, so you don’t have to worry about charging it all night long.

1. Turn on "Optimize battery charging" and let the phone learn to manage power by itself

This feature is specially designed by Apple to solve the "overnight charging" problem.

Its working principle is very considerate, the phone will automatically learn your waking up habits.

For example, if your alarm clock rings at 7 a.m. every day, when charging at night, the system will quickly charge the battery to 80%, and then stop it steadily at the designated place.

When it’s almost an hour before you get up, it will quietly charge the last 20% of the battery, reaching 100% just when you need to activate your phone.

As a result, the battery will not be under the high-voltage state of full charge throughout the night. The chemical pressure inside it is much smaller. As a result, the aging rate will naturally be slowed down.

Actual tests have been conducted on many machines. After turning on this function, the battery health of those machines that have been used normally for a year can basically be stably maintained at above 90%.

The setting method is extremely simple: open "Settings", then enter "Battery", then enter "Battery Health and Charging", and finally turn the "Optimize Battery Charging" switch to green.

From now on, plug it in before going to bed and don't have to worry about it at all, which is very worry-free.

2. Turn off background app refresh and no longer secretly consume power when the screen is locked.

Before going to bed, the battery of the mobile phone was still 70 to 80%. However, when I woke up and checked it in the morning, the battery had inexplicably dropped by more than 10%. Have you ever encountered such a situation?

This is probably Background App refresh Making trouble.

Especially WeChat, short videos, news, and shopping apps. When you go to sleep, they are not idle. Instead, they secretly perform network operations in the background to refresh content and receive messages. This not only consumes your data, but more importantly, it often wakes up the battery and processor, thereby increasing the number of unnecessary charge and discharge cycles.

After turning it off, the system will put these apps into a deep sleep state completely when the screen is locked and the phone is not in use.

After a whole night, after actual testing, in pure standby mode, the power loss was more than 10%, but it was actually reduced to 2 to 3%, and the effect was immediately apparent.

And you can rest assured that turning off this function will not have any impact on the normal push of WeChat messages. The messages will still arrive according to the original rules.

According to the operation method, first open the option named "Settings" in the system interface, then find the "General" option and click it, and then find the "Background App Refresh" option group under "General". At the top of the option group is the "Background App Refresh" option. Click on this option directly to select the "Off" state, or just keep a few software that you really need and need to be updated in real time.

3. Set automatic lock to 30 seconds to prevent power consumption and heat generation when the screen is on.

Many people put their phones away randomly after using them, and the screen is still on, maybe after a minute or two, it turns off on its own.

Don't underestimate these one or two minutes, because a little adds up to a lot, so the amount of power wasted throughout the day is considerable. More importantly, if the screen is on for a long time, especially when the screen is still on while charging, the phone will heat up significantly.

High temperature is the most serious nemesis of lithium batteries. The damage it causes to the battery is more than ten times higher than charging overnight, not just a little higher.

Set the automatic lock time to a minimum of 30 seconds. When the phone is placed down and there is no operation within 30 seconds, the screen will automatically turn off and lock.

This little habit can keep the fuselage in a warm and cool state during the entire charging process, and you basically don't feel the heat getting very hot.

Go to the settings path, that is, enter from the "Settings" option, then find "Display & Brightness", then find "Auto Lock" here, and finally select "30 seconds" from there.

This setting not only saves power, but also protects the battery from high temperature damage, killing two birds with one stone.

4. Turn on the battery percentage and charging beep, and the charging status is clear at a glance

Especially when the elders in the family use their mobile phones, they often don’t know whether they are charged or not.

Sometimes, the socket is not plugged in firmly, or the charging head is faulty. I thought I had charged it all night, but it turned out to be empty. When I went out the next day, the phone's battery was completely exhausted.

This situation is called Loss of power , causing great damage to the battery.

Turn on the battery percentage display to clearly see how much battery is left.

When the charger is plugged in, the phone will beep or vibrate, and when the power is unplugged, there is still feedback, which makes me feel really confident.

In this way, it is prevented from repeatedly turning on the screen to check the battery level, and it also completely eliminates the embarrassing situation of "thinking it is charging but actually not charging".

The method is to turn on the battery percentage: first click to go to the "Settings" window, then find the "Battery" option, and then click on the "Battery Percentage" switch.

There is no need to separately set the charging sound. In the iOS system, the sound and vibration will appear by default when the power is plugged in. Just pay attention to it.

5. Understand two key concepts: battery health and cycle times

If you want to take good care of your battery, you must first understand two words.

The first one is Battery health , you can understand it as the current "stamina value" of the battery.

New mobile phones leave the factory at 100%, and will slowly decrease with use.

When it is below 80%, you can clearly notice that the phone is no longer durable after the same full charge.

The second thing is the number of charging cycles. To put it simply, this is what happens when you charge the battery from 0% to 100%. This counts as one cycle.

The design life of Apple's battery is about 500 cycles, at which time the health will drop below 80%.

Note that just charging once is not considered a cycle. For example, if you use 50% of the power today and then charge it full, and then use 50% of the power tomorrow and then charge it again, only the sum of these two times is considered a cycle.

Therefore, reducing deep discharge (until automatic shutdown) and preventing long-term full-charge static state can make the cycle number decrease more slowly.

6. Remember these three points when charging daily. The longer the battery is used, the more durable it will be.

Shallow charge and shallow discharge is the best habit.

Don't wait until the phone's power is exhausted until it can no longer alarm before charging. When the power drops to 30% to 40%, plug it in for charging. When it reaches 80% to 90%, just unplug the charger.

There is no need to pursue 100%, and don’t use automatic shutdown frequently.

Just like when people eat, they feel most comfortable when they are seven to eight times full.

second, Take off heavy phone cases when charging .

Many anti-fall cases have extremely poor heat dissipation, and the heat cannot escape during charging. The battery is like working in a small oven, and its aging rate will be much faster.

Remove the shell and allow the heat to dissipate naturally.

third, Turn on airplane mode and recharge Can be twice as fast.

If you are in a hurry to go out but the battery is low, plug in the charger, turn on the "airplane mode", and then turn off Bluetooth and positioning. In 15 minutes, you can easily charge about 30% of the battery. It is extremely practical and will never cause damage to the battery.

7. Perform power calibration once a month to avoid false power and power outages.

Sometimes, you will find that the battery level display of your mobile phone is inaccurate. For example, the battery level of the mobile phone suddenly drops from 30% to 10% even though it is clearly being used. Another example is that the battery level of the mobile phone remains at 100% even after being used for a long time. This is a false battery condition.

The solution is simple, take time out once a month to do a complete battery calibration .

The method of operation is to use the phone's power to less than 20%, and then charge it to 100% at once. Do not unplug the charging cable after it is fully charged, and then continue charging for ten to fifteen minutes.

This process can enable the power detection chip inside the battery to re-learn, and the power display will become extremely accurate, preventing power jumps and preventing the battery life from being good or bad.

Finally, let’s clearly state the core conclusion, that is: Apple mobile phones can be charged overnight with peace of mind. In fact, the real damage to the battery is never the charging time, but those wrong habits such as not turning on optimized settings, getting hot when charging, frequently using it to automatically shut down, and wearing a thick case that leads to poor heat dissipation.

All the methods shared today are the native settings of the iPhone itself. There is no need to spend a penny or download any software. They can be used on all series of models. Middle-aged and elderly people can just follow the steps and click without any operational risks.

If you continue to do so for a long time, the rate of decline of your battery health will be significantly slower, and you will not need to replace the battery for two or three years of normal use.

In the future, you can plug in the charger before going to bed, and then you can sleep peacefully. From now on, you will no longer have to worry about getting up in the middle of the night to unplug the power.
