Update ios16 power consumption fast charge into the cause and solution:
< br >
1. Turn on the \"optimized battery charging\" After updating the iOS system, especially if the charging is slow to 80%, this situation is not a fault, but may turn on the \"optimized battery charging\" function. This mode can learn your daily charging pattern and suspend charging to more than 80%. Therefore, after updating the iOS system, it may be due to the opening of this function setting, resulting in significantly slower charging of the iPhone, or even a situation where the power does not change for half a day.

2. Forced iPhone restart Due to the update of the iOS system, some problems such as fast power down, no charging, slow charging and so on, generally restart the iPhone forcibly restart the connection can be restored. Full screen models (iPhone8 and later) Forced restart operation: quickly press the volume up and down keys, and then continue to press the on key until the Apple logo appears after the black screen of the iPhone, release the button and wait for the iPhone to restart.

3. After the iOS system is upgraded\/demoted or jailbroken, the iPhone has problems such as fast power failure, failure to charge, and slow charging, which are most likely caused by iOS system faults.

The controller is damaged and the main control board needs to be replaced. After the ISO 16 upgrade, the iPhone cannot be charged with 20 watts fast charge, indicating that the control board cannot be configured with voltage. Therefore, you need to replace the main control board in time
Because the fast charge is not activated, the fast charge function of the mobile phone can allow the mobile phone to charge quickly, and when the fast charge function fails, it will charge at the basic power, which will be manifested as a slow charging speed.

There are many fast charging protocols, each is different, activate fast charging requires a mobile phone, charging head, charging line three match, fast charging failure priority check whether the replacement of charging head or charging line.
Iphones have never been fast charged. It is normal for the mobile phone Apple to upgrade iOS 16 without fast charging function, because the current mobile phone Apple does not have fast charging function, the highest is more than 20 watts of a charging power, so no matter how many systems are upgraded to iOS, there is no fast charging function.
Whether the charging port of the iphone body is blocked by foreign bodies or too much dust, it is easy to cause poor contact of the charging cable. Phones are often left in pockets or bags, which can cause small particles to block the charging port.
It may be that too many apps are opened, you can shut down and restart it, and then charge it again.

If there are no special circumstances, you can also shut down first, and charge it in the shutdown state.
< br >
Shut down also can not charge into the electricity, it should be the battery is broken, you can consider changing the battery. You can also try it with a more powerful charger.

Display charging, do not use the phone, can charge slowly, use the phone while charging power off, most of which is the data cable\/tail plug damage,
