Because of its natural closed source system, apple mobile phone does not support many daily format files. So what's the format of Apple ringtones? In fact, all Apple device ringtones are in AAC format. That is to say, ordinary MP3 and other format files cannot be recognized as ringtones by Apple devices. Before changing the ringtones, we need to first set the ringtone file to AAC format, and then convert it to m4r format file to import it into Apple phones<

it is normal for the old apple phone to become stuck after upgrading to the latest system. After all, many functions of the new IOS are designed for the new phone, and the hardware performance of the new iPhone is different from that of the old one. Although your iPhone 6 plus was purchased in 2015, it was released in 2014 after all. It has a history of three years, and the hardware configuration can't keep up with the latest IOS 11<

Apple a11 processor on newly launched iPhone 8 / 8 plus and iPhone X, It has two high-performance cores (large core) and four high-efficiency cores (small core). The performance of large core is 25% higher than that of the previous generation A10, that of small core is 70% higher than that of the previous generation, and that of multi-core is 75%

Apple's A10 processor is 40% higher than the previous generation A9, and the A9 is 70% higher than the previous generation A8. In other words, the performance of the six core a11 processor of the iPhone 8 is four times that of the al core processor of the iPhone 6 plus

in addition to the processor, the operating memory (RAM) of iPhone has also changed greatly in recent years. The operating memory of iPhone 6 plus is 1GB, iPhone 8 is 2GB, and both 8 plus and X are 3gb< In other words, the overall performance of this year's iPhone 8 plus and iPhone x is at least three times that of 2014's iPhone 6 plus. Under such a gap, no matter how optimized IOS 11 is, the experience of iPhone 6 plus is much worse than that of iPhone 8 plus and iPhone X. If the system experience of iPhone 6 plus is the same as that of iPhone 8 and iPhone x, how can Apple persuade users to buy a new phone

some users even speculate that there are various "negative optimizations" in Apple's IOS 11, the purpose of which is to make the old models become stuck, so as to speed up the user's replacement. Therefore, there is a saying of "alternate generation upgrade" in general Apple mobile phones, which means that if the original system of the mobile phone is IOS 8, then it can be upgraded to IOS 10 at most, and then IOS 11 should never try

however, many users upgrade their iPhone 6 plus to IOS 11 without knowing it. Now it's done, and it's impossible to upgrade IOS 10. So how to solve the problems of stuck and fast power consumption

in fact, there are many optimization methods for IOS 11 system, including online search, such as turning off dynamic desktop, turning off background application refresh, turning off WiFi power, turning off Siri and so on. Moreover, if some key functions are turned off, the mobile phone will become very difficult to use, but not necessarily smoother

however, some netizens recently found that IOS 11 has a "down frequency" mechanism. The specific performance is: when the power of the mobile phone is less than 50%, the frequency of the CPU will automatically rece and the computing speed will slow down. The purpose of this is to save power and prolong the use time of the mobile phone

however, the processor performance of old mobile phones such as iPhone 6 plus is not enough, and the frequency rection will definitely become extremely stuck. In the power saving mode, once the power of the mobile phone is reced to less than 10%, the system will become very stuck, which will be relieved only after the charger is plugged in

although the design of frequency rection is boring, it also provides us with an idea: as long as the power of the mobile phone is kept at more than 50%, the processor will not rece the frequency and the phenomenon of stuck will be reced accordingly

therefore, iPhone 6 plus and other old models of Apple mobile phone users can carry chargers or power bank with them to keep the power of the mobile phone above 50% all the time, so as to prevent the jam caused by the frequency rection of the processor< Mobile phone is too laggy. Br />
of course, iPhone 6 Plus is mobile phone three years ago, and when it is normal to retire, if you think the cell phone is too stuck, you can consider replacing the latest iPhone 8 or iPhone 7 Plus. When Apple releases IOS 12 or higher in the future, it's better to check the experience and evaluation of other users before upgrading to avoid being cheated by apple
