Why is Samsung's rechargeable battery not fully charged?

If the phone is not fully charged, it is recommended that you:

1. Try to reinstall the battery (possibly due to poor contact).

2. It is recommended to replace the power socket as much as possible.

3. Check whether the original battery and seat charger are used. If not, it is recommended to replace Samsung original accessories.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card, battery and seat to the local Samsung service center for professional engineers to help you test.
