Why am I afraid that my phone is not charging properly and keeps stuck at 85

This is the structure of its charging method: (unplug the power cord after charging for a period of time, and the phone shows that the power is full) In fact, this is a virtual power. I also use this machine, and I still make batteries professionally, so I have quite a lot of experience.

The original charger is a fast charge, and the two-hour charging time is actually not enough as you said.

Summary. The mobile phone can't be charged when it is charged to 85, and there is no problem with the charger, as follows: Pro, hello, how to deal with charging exceptions: 1. Check whether the "Optimize Battery Charging" function is turned on:

When it is recognized that the mobile phone is in continuous long-term charging (such as charging overnight, etc.), the charging will be suspended after the charging reaches a certain power ratio, so as to avoid the battery being in a fully charged state for a long time to accelerate the aging of the battery and prolong the service life of the battery. You can turn this feature off the attempt; Note: If the phone does not have this switch, it does not support this function.

2. There is a problem with the battery level display: turn off and restart, check whether it returns to normal; 3. Use the standard charger and data cable for charging, non-standard chargers and data cables may not be compatible with the mobile phone, resulting in failure to charge. If there is a fault with the standard charger and data cable, it is recommended to go to the customer service center for testing; 4. Check whether the charger and socket are in good contact, and try to replace the socket; Check the mobile phone charging port for foreign objects, corrosion, dirt, liquids, etc., if there is such a phenomenon, go to the customer service center for testing.

5. If the mobile phone exceeds or falls below a certain temperature value, it may not be able to be charged, so try to change the charging environment; 6. If the phone is not used for a long time or the battery is automatically turned off, the battery is in an over-discharged state, it is recommended to charge it for 30 minutes before checking.

Xiaomi mobile phones can't be charged when they are charged to 85, and there is no problem with the charger.

The mobile phone is charged to 85 and cannot be charged, and the charger does not judge the problem of virtual withering, as follows, hello charging abnormal handling method: 1. Check the hole to see if the "Optimize Battery Charging" function is turned on: Enter Settings - Battery - Charging Settings to see if the "Optimize Battery Charging" function is turned on, the function will intelligently learn historical charging habits, when the mobile phone is recognized in continuous long-term charging (such as charging overnight and other scenarios), the charging will be suspended after reaching a certain proportion of power, Avoid the battery from being fully charged for a long time to accelerate the aging of the battery and prolong the service life of the battery.

You can turn this feature off the attempt; Note: If the phone does not have this switch, it does not support this function. 2. There is a problem with the battery level display

Shut down and restart to see if it returns to normal. 3. Use the standard charger and data cable for charging, non-standard chargers and data cables may not be compatible with the mobile phone, resulting in failure to charge. If there is a fault with the standard charger and data cable, it is recommended to go to the customer service center for testing; 4.

I've tried all of what you said, and none of them are broken.

It's a data cable. It's broken.

This condition is usually caused by the malfunction of the phone charger. If the actual output voltage of the mobile phone charger is lower than the rated output voltage, when the mobile phone battery voltage rises to a certain value but the battery is not fully charged, the current voltage of the mobile phone battery is consistent with the output voltage of the charger, so there is no voltage difference, and the charging stops.

It is recommended to replace the charger for testing. If the device stops charging when it reaches 80% charge: Your iPhone may heat up a little while charging.

In order to prolong the use of the battery, if the battery is too hot, the software may limit the charge after the charge reaches 80%. When the temperature drops, the iPhone will recharge.

iPhone turns on Optimized Battery Charging.

Back in iOS 13, Apple added the "Optimized Battery Charging" feature to the iPhone. This feature improves battery life by reducing the amount of time your iPhone spends fully charged.

When this feature is enabled, in some cases, your iPhone will delay charging by more than 80%. iPhone uses machine learning on the device to learn the user's daily charging habits and enables Optimized Battery Charging only when iPhone determines that it will be connected to a charger for an extended period of time.

When Optimized Battery Charging is enabled, a notification appears on the Lock Screen indicating when your iPhone will be fully charged. If you need to fully charge your iPhone as soon as possible, touch and hold the notification, then tap Charge Now.

Summary. Hello pro 1, the mobile phone can't be charged, of course we have to find out which piece is wrong, only if we find the problem can we prescribe the right medicine. Let's take a step-by-step step review of what the problem is.

2. First of all, connect the mobile phone with the charger and plug it into the plug board to see if it can be charged. If it can't be charged, then the current possible problems are: the charger is broken, the connection line is broken, the mobile phone interface is broken, the battery is broken, the system problem is then eliminated 3, change a connection cable or change the charging plug, and then charge, to see if it can rush into the power, if the power is rushed, then it proves that it is a problem, change the wire, or change the charging plug.

Pay attention to the current and voltage of the original charging plug of your mobile phone when changing the charging plug to prevent harm to the mobile phone. If you can't rush, then the possible problems are: mobile phone interface problems, battery problems, system problems 4, remove the battery (if you can't disassemble it, don't force it to be dismantled), use the universal charge to flush, if it is the problem of the mobile phone charging interface, if not, then continue to check the possible problem:

Battery, system 5, change the battery to see if you can rush in, if you can charge it after changing the battery, it is likely that the battery is scrapped. Just change the battery. If it still can't be charged, then it can only be a problem with the system.

The reason why the phone can't be charged when it reaches 81 is that Apple's official website says that if the device stops charging when the power reaches 80%:

Your iPhone may get slightly warmer while charging. To prolong the life of the battery, if the battery is too hot, the software may limit the charge after the power reaches 80%. Your iPhone will charge again when the temperature drops, try moving your iPhone and charger to a cooler location.

First of all, let's talk about why it is difficult to charge the mobile phone to 100%, in fact, the reason behind this is very simple, that is, because the batteries of our smartphones are lithium batteries. Unlike the previous nickel-chromium battery, the lithium battery can be charged and used at any time, and the service life is longer, but it is not like the nickel-chromium battery needs to be fully charged, but it is charged to about 80% It has been satisfied, so in order to make the battery service life longer, the current mobile phone manufacturers will set up charging protection. And this charging protection is the main reason why it is difficult for us to charge the phone to 100%, because when the phone is about to 100% charge, the charging mode is changed to trickle charging, so as to protect the battery.

So why is it said that the battery is not fully charged, it means that the mobile phone is very good, in fact, the reason is because the mobile phone with insufficient power (battery damage does not count!) It means that the battery is still very new, and the battery protection is also working normally, so in general, new phones are difficult to charge. If your phone is always 100% charged, your phone's battery may have started to age, and your phone's power consumption may be faster.

But then again, in fact, mobile phone charging is also a science, today's lithium battery mobile phones are best to start charging when the battery is less than 20%, and wait until 80% to start using it, rather than waiting until it is turned off immediately, and then charging the phone to 100%.

Now mobile phones basically have a fast charging function, and the charging speed will be very fast before the power is less than 80%, and after 80%, the speed will decrease, so in order to save time, you can stop charging after the mobile phone reaches 80%, so that there will be less time wasted. Of course, I would like to tell you here that in fact, the battery also has its own service life, if you want the mobile phone to provide you with longer service, in daily use, you need to protect the mobile phone battery, in your daily life, will you get used to charging the mobile phone to 100%.

Due to the wrong way of use, the storage capacity of the battery is reduced, which will cause this phenomenon, do not play with the phone while charging!

Wait 1 hour to see, it will take a long time to see 99%-100%.

Operating system: Android

The mobile phone manuscript is charged to 95 and is not fully charged, which may be caused by the system display data disorder, the system charging display problem, the plug is not plugged in properly, etc., as follows:

1. The system display data is out of order (as shown in the figure below), although the charging icon has been displayed in the charging is not full, but in fact, the power of the mobile phone is already 100%, turn off and restart to check the power display, and the power display will be automatically corrected after the system restarts.

2. There is a problem with the system charging display (as shown in the figure below), if you encounter this problem, it is recommended to re-flash the Apple mobile phone system to solve it, open the Apple mobile phone settings, enter the general one, press Restore to erase all content and settings, and restore the factory settings of the mobile phone.

3. It may also be because the plug is not plugged in properly when charging, then replug the Apple mobile phone charger data cable and recharge it (as shown in the figure below).

Precautions for phone charging:

1. Use the original charger: the current is unstable in the non-original charger, and the inferior power bank or charger is also easy to cause the battery to overheat and cause danger.

2. Pay attention to the damage of the charger: before charging, it is best to check whether the data cable of the charger, including the charging head, is in good condition, and once the shell is damaged and the metal is exposed, it should be replaced in time.

3. Pay attention to power consumption: the mobile phone battery is a new type of lithium battery polymer, and the battery can not be used to the extreme state to recharge, when the power is less than 20%, a red alarm will be issued to prompt charging, and in the case of non-necessity, the power can be charged to 80% to pull out the key family charger, do not wait for the battery to be fully charged and continue to charge, in addition, do not charge all night. <>

Mobile phone charging is based on voltage, current counting, etc., so it may not be charged to 100%, in fact, mobile phone charging is not 100% in the absolute sense. Although there is trickle charging, but trickle is only to maintain the battery detection after the full power of the measure, the seat charge detection battery full voltage is, theoretically speaking, the battery will be charged to more than 90 percent, so theoretically it is relatively normal to charge to more than 90 percent.
