When buying a new mobile phone, many people will hear such advice: "The first charge should be fully charged for 12 hours" and "The first three times, the battery must be fully used and then fully charged to activate the battery." These sayings have been passed down from generation to generation by the elders, and are even regarded as "maintenance secrets" by some businesses. However, these suggestions actually come from battery technology that has long been obsolete. This article will trace the origin of the saying "activate the battery", analyze the characteristics of modern lithium batteries, and provide a scientific guide to charging new mobile phones.

Many people have heard the saying that "it is better to charge the phone after it shuts down automatically". Some people think that this can "calibrate the battery", while others think that it can extend the battery life. However, this concept actually originated from the early era of nickel-metal hydride batteries and is not applicable to the lithium batteries of modern smartphones. This article will explore the characteristics of lithium batteries in depth, reveal the truth of this misunderstanding, and share scientific charging suggestions.

With their flexibility and powerful shooting capabilities, drones have become a powerful tool for aerial photography, mapping, agriculture and other fields. However, many pilots have found that the life of drone batteries seems to be shorter than that of batteries for other devices. A brand new battery may have problems such as significantly reduced battery life, slower charging speed and even swelling after dozens of flights. What scientific principles are hidden behind this? How can we effectively extend the battery life? This article will deeply analyze the key reasons for the aging of drone batteries and provide practical maintenance guidelines.
