Apple as one of the world's largest cell phone manufacturers, the annual shipments of up to 200 million, it is clear how popular the iPhone phone. But the higher the number of cell phone shipments means that the probability of encounters will also be greater. There are many people who have complained that they have bought a year of iPhone, and the range has become particularly poor.iPhone's battery life capacity many people have seen in the past has been unable to compare with the flagship Android phones, but after a year of use the battery life will become very poor is somehow unjustified, if you encounter this problem, usually affect the iPhone battery life for only three reasons, respectively, the system, screen and battery.If you find that your iPhone battery life has suddenly become worse, you can think back to whether you have recently upgraded the iOS system, some versions of Apple's system does have serious bugs, power consumption problems are very obvious, this problem Apple will generally be a short time to repair, system upgrades to the latest version, the problem will be able to significantly improve.Then is the reason for the screen, from the iPhone X to a number of Apple products used are OLED screen, this screen has a feature that can be intelligent power saving, users can "Settings - General - auxiliary functions - display adjustment - flip color" to open the "smart flip", white flip to black can be more power saving.There is another reason why the phone's battery is really a problem, we can find the "battery health" item in the iPhone's battery settings, showing the maximum capacity of the battery percentage, used to indicate the remaining battery life, generally higher than 80% belong to the normal category, this time can be used normally.When the number of charge cycles of the battery reaches 500, the maximum capacity of the battery should be maintained at a maximum of 80% of the initial capacity, if it is lower than 80% it means that the battery has been seriously damaged, there will be a situation where the battery life becomes very poor. New country machine within a year the maximum capacity of the battery is less than 80%, Apple official is packaged after-sales free repair, such a short period of time is obviously a battery failure.If the phone after the warranty time, found that the maximum capacity of the iPhone battery has been lower than 80%, Apple's official after-sales service also provides paid replacement services, in addition to some professional repair stores also provide battery replacement, but be sure to choose a reliable repair store, because they replace the battery will be more secure.Usually, the Apple phone using a year of poor battery life is the above several problems caused, in fact, the first two can be solved, is the battery health problems, related to battery replacement will need to spend money to solve, if you do not intend to replace the battery, as long as it is able to discharge normally is also possible to continue to use.Then again, Apple officially and certain third parties also provide some practical solutions, such as support for 18W fast charging from iPhone 8, which can restore power to the phone relatively quickly; there is also the use of clip-back battery, although it will make the phone become thick and heavy, but the range will be significantly improved.If there is no problem with the battery, daily use to improve the battery life, you can adjust the following methods.1, close the software automatic update systemWhen we use the phone is there often a window pops up to prompt us to update the system? If you don't need it, turn off this function, it's useless and power hungry.2, close the background application refreshWhen we finish using an APP, we will think that the exit is to close the APP, in fact, it is not, the APP is still running in the background, power consumption and traffic consumption. How to really close these APPs?3、Close SIRI Although the intelligent voice Siri is fun, but it is also an extremely power-consuming function!
