-Try to change the charging cable or adapter, if can solve the problem, that's the reason of broken cable or adapter. -Try the magnetic charging. If can charge the phone well, the problem may be caused by wrong USB port. If can't charge either, your battery may be broken and need a replacement. - If new battery can't save your phone, you need take it to check the motherboard.
