The second method: first use the battery to 20% and restore all settings. Remember, this is not an erasure. Restoring settings will not erase any data. After the settings are restored, plug in the charger and charge it to 100. Then unplug the charger, turn it off, plug it in, turn it on, charge it for half an hour, and unplug it.
At this point, the battery calibration of the iPhone has been completed. You can try both methods, if you still can't solve the battery failure of iPhone. I suggest you go to the maintenance station to change the battery of your mobile phone.
