Currently, the highest official version of Apple iOS firmware is iOS11.3, which can be analyzed as follows:

1. The highest beta version of firmware is iOS11.4beta1. As for which iPhone 6s to use? It is really impossible to define whether the system version is good, because based on Apple’s past experience with iOS firmware versions, even if it is the same model and the same system version, many people will report different problems.

2. My iPhone6s was purchased in May 2016. The system was iOS9.3.5 when I bought it, and was later upgraded to iOS10 and now iOS11.3. Originally, I also flashed the iOS11.4beta1 firmware, but it felt like it was getting too hot and the power consumption dropped back to iOS11.3.

3. If you want the smoothest 6S, it is recommended to stay in the 9 system. The 6S 9.3.1 currently in my hand is smoother than my wife’s 710.3.3 in daily use. If you want the most balanced experience, it is recommended to stay in system 10. 10.3.3 is very good. It has more functions than system 9 and is more practical.

Many people currently report that the 4.11 system generates high heat and consumes power quickly. It mainly depends on which version the phone is currently stuck on. For system 11, simply upgrade to 11.3. For other systems, it is recommended not to upgrade. It will be fine for another 2 years. If the battery is old, replace it as soon as possible. Now the official Decai 218 is very easy to use. I just changed the battery in March, and now the phone is very smooth. The battery is fully sufficient for normal use. One charge a day. If you are willing to spend several thousand dollars, don’t worry about the more than 200 yuan. The experience is much better. Extended information

1. Apple has not yet announced any plans to let iPhone run Java. But Sun Microsystems has announced its plan to release a Java Virtual Machine (JVM) that can run on the iPhone, which is based on the Micro

Edition version of Java. This will allow Java applications to run on iPhone and iPod

Touch.

2. After the announcement of this plan, programmers who are familiar with the iOS software development agreement believe that although the iOS software development agreement does not allow applications to run in the background (for example, running the program while answering a phone call),

But it allows built-in applications to download code from other sources, and they can also interact with third-party applications (such as Safari and Java Virtual Machine), which may hinder cooperation with Apple. The development of the Java Virtual Machine. Clearly, the Java running on the iPhone is outside the scope of the iOS Software Development Agreement.
