It took 12 hours to charge the mobile phone. I saw that the charging was completed, but there were only two boxes on the screen after the phone was turned on. Is there something wrong with the phone?

It took 12 hours to charge the mobile phone. I saw that the charging was completed, but there were only two boxes on the screen after the phone was turned on. Is there something wrong with the phone? Or a battery The first thing you should consider is the receiving screen, because the current mobile phone batteries have built-in management chips, that is, once the batteries are fully charged, they will not be recharged. Although your battery will not be recharged after charging 12 hours, once it is fully charged, the probability related to the battery is still relatively small. There is probably something wrong with your screen. I suggest you send it to the after-sales service department for testing.
