1, there are two reasons for this situation: the battery itself: cheap products, the use of no protective battery or secondary production of batteries, resulting in no charge discharge protection of the battery, and the phenomenon of unsaturated charging after six months. It is also possible that the electronic components on the protection board are damaged, resulting in the inability to 100% charge and discharge. Mobile phone system or version problems: some mobile phone systems or Bluetooth versions do not match, resulting in parsing data errors, but this possibility is very small.
2, the general battery after 2After 00-300 charging cycles, the capacity will remain about 80%, that is, how long it can not be full. The protection IC is damaged. Without overcharge or overdischarge protection, the battery will be damaged and the capacity cannot be full. If the charging plug and charging cable have not been changed, the product has not been in water, there is no serious extrusion or beating, and the use period is within half a year, you can find after-sales treatment, which should belong to the product itself.
3. The battery is damaged. There is also a battery inside the Bluetooth headset, the battery is damaged, there will be only 80% of the situation, the need for timely replacement and maintenance.
<4, AirPods can only charge 80% of the power solution: pick up your iPhone, go to the iPhone Settings screen, in the "battery" option, find the "battery health" page, turn off the "optimize battery charging" switch.iPhone14 charge to 80% can not be charged Why wireless charge can only charge 80% Reason such asNext Why can wireless charge only 80% : The temperature is too high. It may be because the battery temperature of the Apple phone is too high Why the wireless charge can only charge 80%, when the charge reaches 80, the system automatically restricts the charging. The hardware is damaged. The battery is aging. The charger power is insufficient. The battery health is abnormal. System problem. Expanding your knowledge: The iPhone is a line of mobile phones powered by Apple Inc. 's iOS operating system that went on sale on Jan. 9, 2007.
This condition is usually caused by the fault 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 that 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: The iPhone may heat up a bit while charging.
In addition, there are some factors that may cause the charging to stop at 80%. For example, the charger or charging cable may malfunction, orGame side charging, even the environment is too hot, etc., can cause the iPhone 8 battery can not be charged continuously.
2, environmental factors The charging environment may affect the charging effect. If the mains voltage is unstable or the ambient temperature is low, you can try to change the charging environment or use the computer USB charging. Try charging after shutting down to see if you can charge normally. Replace the cable or charger If possible, try to replace the cable or charger for charging.
3, Apple 12 charging to 80% of the stop may be because the "optimize battery charging" turned on, closedThat's it. Start by opening Settings on your phone. After entering the Settings screen, slide down to find and tap "Battery". Then click on "Battery Health," then turn off "Optimize battery charging," continue to click on "Off."
