Low temperatures can affect battery activity and lead to slow charging. If the ambient temperature is normal (0℃ to 45℃) and the charging is slow, it is recommended that you try the following operation methods: 1, use the original charger to charge, check whether the full charge time is longer when the shutdown charging; 2, if only boot charging appears, it is recommended to close all background procedures before charging (drop down menu, click a key to clean up); 3, replace the power socket charging attempt; 4, After backing up important information (contacts, multimedia files, etc.), and then restore factory Settings (setting - system \"more\" - restore factory Settings, do not check \"completely clear\"). 5, if there is still a slow charging situation should be a battery fault, it is recommended to replace the battery test. If the problem still exists, please bring the purchase invoice, warranty card and machine to the customer service center for testing, and professional engineers will solve it for you.
