The following operations are generally recommended for Samsung mobile phones:
1. Use the original charger to shut down and charge, and check whether the phone is slow to shut down and charge.
2. If the phone only charges slowly when the phone is turned on, please: (1) End the background running program (the latest application key in the lower left corner - End) (2) Uninstall the third-party battery management software in the phone. If the above operations do not work, see more solutions: (1) Check whether the phone has a version update and upgrade to the latest version. (2) Please back up the data in the phone and restore the phone to factory Settings. (3) If the above methods are ineffective, please bring the purchase invoice, repair card and machine to the service center, by professional after-sales engineers to help you deal with.
