Try disabling Optimise Battery Charging
The algorithm aims to ensure that your iPhone is still fully charged when unplugged. Optimised Battery Charging is turned on by default when you set up your iPhone or after updating to iOS 13 or later. To turn the feature off, go to Settings > Battery > Battery Health & Charging and turn off Optimised Battery Charging.

"If Optimised Battery Charging won’t activate
Optimised charging is designed to only engage in locations where you spend the most time, such as your home and place of work. The feature won’t engage when your usage habits are more variable, such as when you travel. Because of this, some location settings must be enabled for Optimised Battery Charging to activate.* None of the location information used for this feature is sent to Apple.
Make sure these settings are enabled:
- Settings > Privacy & Security > Location Services > Location Services.
- Settings > Privacy & Security > Location Services > System Services > System Customisation.
