What will happen if the iPhone 6s does not upgrade the system? Can the iPhone 6s continue to be used without upgrading?

You may not upgrade the iPhone 6s system because you are worried that the phone will become stuck after upgrading the system. When the iPhone 6s was first launched, it was equipped with the IOS9 system. Now it seems that IOS9 can still support most APPs. However, with the emergence of IOS13 and other systems in the future, more and more APPs will no longer support the IOS9 system. If you do not update the system by then, you will only be able to use the existing old version of the APP, and many functions may be missing and the user experience will be degraded.

What will happen if the iPhone 6s does not upgrade the system 

Theoretically it is possible, but reality does not allow it

The iPhone 6s is the flagship product released by Apple in 2015. It is equipped with an A9 processor and does not feel stuck at all under the operation of the latest system iOS 12. It has been almost four years now. If the iPhone 6s stays on the iOS9 system without upgrading, the phone should be in the best condition. In addition, regardless of factors such as electronic components and battery life, the iPhone 6s can still be used forever.

The battery life of Apple mobile phones is obvious to all. Under normal circumstances, the original battery will suffer a lot of battery loss after three years of use. The most direct manifestation is that it is charged once a day at first, then three times and four times a day. If you want your iPhone 6s to last forever, replacing the battery is unavoidable. The battery of the 6s I used before has been replaced once so far. After the replacement, the battery life has obviously returned to the same level as before. It feels like it can continue to fight for another three years.

Can the Apple 6s be used forever without upgrading?

Every mobile phone has a service life, and Apple is no exception:

The Apple 6S was released in the fall of 2015. Due to the independence of the system, the hardware of Apple mobile phones comes from Apple. Therefore, the battery life is longer and the use time is also longer. But problems arise over time. A 15-year-old mobile phone has been used for 4 years now. The performance of the hardware will definitely decline after being used for such a long time.

The system is not being upgraded, but its supporting products are being upgraded, not to mention the pace:

The starting point of Apple’s system not being upgraded is definitely to save memory and reduce lag on the phone. But you need to understand that the lag is not caused by the system, and the new system will definitely be smoother. On the contrary, this situation occurs when the old system is incompatible with the software. The reason is that the software will be upgraded after the new system appears, but if your system is not upgraded, it will not be able to perfectly match the upgraded software.

As the times evolve, the use of mobile phones must also keep up with the trend:

For a mobile phone, the most indispensable thing is the technical support of the manufacturer. For example, if a mobile phone is broken and needs to be repaired, where can I find official accessories and where can I buy supporting products for the mobile phone? These are all problems left over from the replacement of mobile phones. For Apple mobile phones, basically a mobile phone will be discontinued in about two years. After the discontinuation of production, it will be no one's child.

So, no mobile phone can be used all the time. Even if the mobile phone can persist, won't you feel uncomfortable using it?
