Why can t the phone be charged when it rushes to 80?

When the phone is charged to 80%, it can't be charged. It's because the phone has turned on the battery optimization mode. Here's how to fix it:

1。Open your phone's settings. 2.

Click on the "Battery" button. 3.Click on "Battery Health".

4.Turn off the switch behind "Optimized Battery Charging" to charge your phone to 80%. Here's why:

2。If the ambient temperature is normal, 15 degrees to 45 degrees, and it still can't be charged, you can try the following methods: use the original charger to connect to the home power supply for charging, turn off the all-in-one and take out the battery, wipe the contact point between the battery and the phone with a cotton swab, replace the battery when possible or try universal charging, and replace the power socket and charger.

What should I do if the battery stops charging after the battery exceeds 80%?

When it is detected that the mobile phone has been in a charging state for a long time in the recent period, the intelligent charging mode judges that this is a behavior that has a greater impact on the battery life, and for the purpose of protecting the battery, the intelligent charging will actively control the power of the battery, which is a normal phenomenon. If you want your phone to fully charge immediately, just turn off the smart charging mode.

Generally speaking, during the life cycle of the battery.

At the end of the period, there will be different degrees of aging and power decay, which may lead to problems such as fast power consumption and easy automatic shutdown of the mobile phone.

Smart Charging Mode: Delay battery aging.

As the saying goes, seven minutes full at each meal is healthy to live to old age, and eating too much will have an adverse effect on human health. Similarly, some fans charge the phone for a long time and forget to unplug it in time, resulting in the battery being in a full state for a long time, which will also accelerate the aging of the battery. Huawei's Smart Charging Mode learns our charging habits to slow down the battery to 100% when needed, so as to prevent the battery from being fully charged for a long time.

The smart charging mode can effectively extend the battery life, and it is recommended to keep it on. The sooner you turn on the Smart Charging mode, the longer the protection time, the more you protect the battery, and the longer the battery life!

This situation is generally caused by a faulty mobile phone charger.

If the actual output voltage of the mobile phone charger is lower than the rated output voltage, then during the charging process, 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 that there is no voltage difference to cause charging to stop. It is recommended to replace the charger for testing.

If your device stops charging when it reaches 80 percent charge: Your iPhone might 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.

Precautions: 1. Use the original charging plug and charging cable.

It is very important to use the original charging plug. Many of today's mobile phones support fast charging, and the fast charging methods of some mobile phones are different, and the voltage and current of different mobile phone charging heads are also different.

A high-power plug will speed up a lot to charge a small power, but it will cause a lot of damage to the mobile phone battery, so you must use the original charging plug to charge the mobile phone. The same is true for charging cables, different charging cable specifications are also different, so be sure to use the original charging cable when charging.

2. Don't charge your phone while playing with it.

Many users like to play with mobile phones while charging, while charging while using mobile phones to play**, play games, watch**, etc. are large current consumption, the current provided by the charger is less than the current consumed by the mobile phone, and the current from the battery needs to be output from the battery while charging the mobile phone. That is, at this time the battery is not charging, but discharging, and even the battery capacity will be quickly "depleted". If conditions permit, it is best to turn off and charge, which is the best maintenance for the mobile phone battery.

The reasons why apples can't be charged when they are charged to 80 are as follows:

1. iPhone turned on the "Optimize Battery Charging" function, as early as iOS13 system, Apple added the "Optimize Battery Charging" function for iPhone. This feature will improve battery life by reducing the amount of time your iPhone spends on a full charge.

When this feature is enabled, in some cases, the iPhone will delay charging by more than 80%. iPhone uses machine learning on the device to learn the user's daily charging habits, and only enables Optimized Battery Charging when iPhone judges that it will be connected to a charger for a long 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 get your iPhone fully charged as soon as possible, touch and hold the notification, then tap Charge Now.

2. Check whether the temperature of the device is too high, if you run a large game or shoot for a long time**, make calls, etc. while charging the iPhone, it may cause the temperature of the iPhone to be too high. If the temperature of the iPhone is high, the protection mechanism will be activated, and the phone will be charged at this time, and the charging may slow down or even stop.

At this time, you should not use your phone for the time being, and place it in a cool place such as a desk to charge. Once the temperature of the device drops, it can be charged normally.
