Is it necessary to perform additional maintenance on the battery?As a consumer, if you don't particularly care about the effects of the aging of the mobile phone battery, you can use it at will without maintenance. For some minority groups with special needs, mobile phone batteries still need some extra maintenance. These special needs may be to leave the old equipment to the family members to continue to use or simply because of the habit of frugality. No matter how small the demand is, it is worthy of attention, so let us take a look at how to maintain the battery.Factors affecting the life of lithium batteriesIn the How to Prolong Lithium-based Batteries article, Battery University introduced in detail the many factors that make lithium batteries age.CyclesIn the article of Battery University, you can also find a similar definition, that is, the depth of discharge (Depth of Discharge) determines the number of cycles of the battery, a complete cycle is 100% depth of discharge, and the actual capacity of the lithium battery will follow The number of cycles/charge cycles increases and decreases slightly. For example, Apple’s commitment to the life of its products’ built-in batteries is that iPhone users’ batteries can retain 80% of their health even after 500 cycles, while the iPad, Apple Watch, and MacBook’s are 1,000 cycles.Deep charge and dischargeWhile evaluating battery life based on the number of cycles, we must also avoid deep charging and discharging. According to Battery University’s statement that “partial charging is better than full charging”, in the case of not pursuing long battery life, try to keep the battery percentage within the range of 30% to 80%.Environmental factorIn addition to the above-mentioned charging and discharging factors, the influence of environmental factors is not small. Extreme high temperatures and high charging voltage will affect the life of the battery. The former will accelerate the irreversible capacity loss of the battery, while the latter can increase the battery capacity, but will accelerate the degradation of the battery's cycle life. In particular, it is necessary to pay attention to the influence of extremely high temperatures. Generally speaking, it is best not to let the battery temperature exceed 35 degrees Celsius.How to carry out battery maintenance by yourselfFor iOS 12 users, wait patiently for the official version of iOS 13 to be released, or join the Public Beta program in advance. When you get iOS 13, you will have the battery maintenance function. You only need to turn on "Optimize battery charging" under the battery health settings. That's it.After turning on this feature, the iPhone will use local machine learning to adjust the charging strategy based on the user's usage habits. For example, when the mobile phone is connected to the power supply all night, the system will only charge the battery to 80%, and then the battery will be fully charged as much as possible before the user unplugs the power the next morning, which avoids deep charging. , Can also guarantee the normal battery life of the day.For Android users, non-Root users can try the "Accurate Battery" application, and Magisk Root users can try the Advanced Charging Controller (hereinafter referred to as acc) module.If you look closely at the user guide for the accurate battery application, we can find that the theoretical basis for battery maintenance is consistent with the battery university. It is recommended that users charge up to 80%, which is said to "extend battery life by 200%."If you want to customize the battery maintenance configuration, for users familiar with the command line, you can enter commands in a shell with root authorization to change settings, view parameters, check working conditions, and export run logs. For ordinary users who are not familiar with command line commands, they can only use ACCA if they want to customize the configuration. ACCA provides a graphical interface that is more user-friendly to most users. It also presets three battery maintenance configurations and adds a display of battery status.What needs to be reminded is that there are risks when the module is flashed and used. If you encounter an unusable or abnormal performance, you can try to read the TROUBLESHOOTING chapter in the instructions, or directly uninstall the ACCA/module to give up. Especially for ACCA, which is still in the early stage of development, in actual testing, the switch of different configurations needs to be manually stopped and started once the acc daemon can take effect.Oriwhiz (Shenzhen DongYe Tengfei Electronics Co., Ltd) is a professional iPhone, iPad, iMac, Mac Book, Xiaomi, Huawei, Samsung, Sony, LG, ASUS repair parts and repair tools supplier.
