Is it okay to upgrade iOS11 for iPhone6?

Since it is the official upgrade of Apple, these relatively old devices can certainly be upgraded. First, let's take a look at the relevant improvements of ios11:

Features: The officially supported devices, iPhone X, iPhone8 and iPhone8 Plus, are pre-installed with the official version of IO11, including iPhone7, iPhone7 Plus, iPhone5s, iPhone SE, iPhone6/Plus and iPhone6s/Plus. 9.7-inch iPad, iPad Air, iPad Air 2, iPad Pro(9.7/12.9 first and second generation, 1.5 inches), iPad mini 2, iPad mini 3, iPad mini 4, and only one device is iPod touch 6. It should be noted that iOS11 is no longer compatible with supporting 32-bit devices such as iPhone5, iPhone5c and iPad4.

Improved features:

1. Control Center You can customize

Our commonly used control centers have great changes: control elements such as brightness, music and WI-FI are divided into grids. If you press a certain part for a long time, it will be enlarged, making it easier for you to operate. After zooming in, more extension options will also be displayed.

2. Do Not Disturb When Driving

Automatically mute the notification while driving, and keep the iPhone mute, and the display screen is closed

You can choose to automatically reply iMessage to the selected contact to inform them that you are driving

3. Directly switch the official version of cellular data

iOS11, so that users no longer have to bother to switch traffic in the "Settings" or set up various Launcher to achieve this goal. As long as you draw the control center, you can find the switch button.

4. With its own screen recording function

Apple has the screen recording function. Similarly, in the notification center, you can directly record the screen by pressing the corresponding button, and the video recorded on the screen will be directly stored in "Photos".

5. Camera

Portrait mode now supports optical image anti-shake technology, HDR and True Tone flash. The new image and video formats of HEIF and HEVC make the space occupied by photos and videos only half of the previous ones. A group of nine redesigned filters are optimized to make the skin color more natural and automatically detect and scan the QR code.

Play the magic Live Photo

On iOS 11, after shooting Live Photo, you can choose three effects: loop playback, back and forth playback and long exposure.

6. The control center is richer than before

The control center of IOS 11 can do much more things than before. Click Settings-Control Center-Custom Control, and you can add the desired shortcut functions according to your actual needs, which will definitely make many people happy.

But don't be too happy. Because of the hardware of iPhone6, CPU A8 and 1GB of memory, running a system like ios may be a little stuck as follows:

Let's take a look at the problems that appear after upgrading iOS11 to iPhone6

1. The mobile phone becomes stuck, the fluency drops greatly

2, and the power consumption of the mobile phone increases obviously

3. Mobile phones tend to get hot

4. WiFi and Internet access speed have decreased

Here are the experimental results

Comparison 1 Boot speed: iPhone SE of iOS 1.3.3 is the fastest, followed by SE of iOS11; Followed by the iPhone 6 of iOS 1.3.3, and finally the iPhone 5s of iOS 11.

Horizontally, the boot speed of the three mobile phones after upgrading to iOS 11 is slower than that of iOS 1.3.3.

comparison 2 boot speed: the iPhone 7P of iOS 1.3.3 is the fastest, and horizontally, the device of iOS 1 is still faster than the corresponding iOS 11.

speed comparison of iphone5s/6/6s/se/7ios11 before and after upgrade: the old model is sad

comparison 3: bright screen of iphone5s, unlocking speed of TouchID, control center, App Store and camera speed.

Comparison 4: iPhone 6 bright screen, TouchID unlocking speed, control center, App Store, camera speed

iPhone 5S/6/6S/SE/7 iOS11 speed comparison before and after upgrade: old model sad reminder

iOS 1.3.3 is still faster than iOS 11 in terms of bright screen, unlocking and camera. However, the card-type multitasking iOS 11 is a little faster

Contrast 5: iPhone SE

This group has the smallest gap. Everything is basically the same

Comparison 6: iPhone 6s

iPhone 5s/6/6s/SE/7IOS11 speed comparison before and after the upgrade: The old model is sad

It is faster to unlock iOS 11 on the bright screen, but the camera is slightly slower. Other things, such as information screen unlocking, settings, App Store, etc. are almost the same

Comparison 7: iPhone 7/7 Plus

Speed comparison before and after upgrading iPhone 5s/6/6s/SE/7IOS11: The information screen/bright screen unlocking of the old model is faster than that of iOS 11, while the camera is still faster than that of iOS 1.3.3, and other experiences are basically the same.

conclusion: upgrading iOS11 card for iPhone6 is a small bug and harmless!

Let's talk about the overall experience of iPhone 6 after the upgrade:

During the use process, the animation transition effect is smooth, but there are occasional jams when switching applications, and some applications will have obvious jams. The power-off feeling is ok, which is similar to before, and I feel that I need to optimize a version. It is also possible that some applications are not fully compatible with ios11, so they will get stuck when used, and I don't know what will happen later.

the official version of ios11 has been pushed: the experience of upgrading the official version of ios11 for iphone6 is slightly stuck. Can you upgrade or not?

and mine is a 32G iphone6, which has as many applications as the picture, and there are more than 4 photos taken by the mobile phone. After the upgrade, there is still 7.6G space left in the mobile phone.

the above is my upgrade feeling. students who can't stand the slight jam suggest not to upgrade the iphone6.

unable to resist the temptation of the new system, my 6 rose to iOS11 with great expectation.

Let's talk about the functions that make me feel high.

No1. The control center can control more contents and improve the setting efficiency.

There is a mobile data switch that was not available before, but now there is one. Long press of flashlight can set different brightness; There are many others, so I won't include them one by one.

No2. Do Not Disturb Driving

After being set in do not disturb mode, the mobile phone can't be turned on even when driving. Haha, I wanted to read WeChat at the traffic lights, but I had to cancel the driving mode to unlock the screen. I have to say that for the safety of myself and my family, this function is still commendable.

No3. The storage space of the mobile phone is more convenient to manage and easier to use

Remember that there was not enough storage before, so we had to delete the application and even the application data. If you want to use this application again one day, the downloaded data will no longer exist. Even if many applications are not used often, they dare not delete them as expected. Now it's different. You can choose to uninstall the application or delete it. If you just uninstall the application and reinstall it later, the data is still there, which is more user-friendly. For example, if your storage is very tight, and you just want to download a big software temporarily, or download some TV movies you want to watch temporarily, you can temporarily uninstall the software that is not used recently, which is estimated to make a lot of space. If you want to use it, just put it back. I am haha at the thought of this.

The new system does bring a lot of convenient and practical functions, but I still have to spit it out: the battery is even less durable. When it is used, the power will be lost, and iOS1.3.3 will not consume so much power.

I don't recommend upgrading, because it will seriously limit the performance of iPhone6. Of course, iPhone6 is on the upgrade list.

Let's take a look at the pits in upgrading iOS11: the more the device is upgraded, the more stuck it is.

This pit should be generally felt by iOS users. Whenever iOS welcomes a new version, there are countless voices telling about the jam brought by the new system. Some media have found that every time a new iPhone is released, that is, when the new iOS system is pushed, the search for iPhone slowness on Google will increase greatly. IOS updates will make devices more and more stuck, which seems to have become a user's knowledge.

John Poole, the founder of GeekBench, a famous scoring software, posted a blog saying that after the upgrade of iOS, the CPU of the old device may be downgraded, and the frequency of running out of low scores will greatly increase. Apple, on the other hand, responded that the new version of iOS system does have performance restrictions on old devices, and the restricted objects are those devices with a certain degree of battery loss, in order to prevent the devices from being shut down unexpectedly-high performance requires high batteries, and the depleted batteries cannot provide the instantaneous high current required for high performance, which may lead to power failure.

new bugs emerge one after another

This is actually not a unique pit of iOS. Many systems will bring new bugs after upgrading, but iOS11's performance in this respect is too unsightly, so it can be mentioned separately. Many users found that after upgrading iOS11, there were a lot of problems, such as infinite restart, camera failure to focus correctly, suggestion error in input method, inability to dial 4-6 digit cornet and so on. App crash incompatibility

For a long time, Apple seems to have paid little attention to the compatibility of old software applications, whether it is macOS or iOS. In the new version of iOS, it is not uncommon for the old version of App to crash frequently due to incompatibility.

the compatibility of the new iOS with the old version of the App is relatively poor. Apple said that if it abandons you, it will abandon your new system and castrate the new function.

It talked about the performance pit, and then talked about the function related. Whenever a new version of iOS is released, Apple always focuses on its new features. For example, Siri, 3D Touch and so on. However, can these seemingly cool new features really be enjoyed after upgrading iOS? Not necessarily. Many new features are only born for new devices, and the functions of the new iOS used by old devices are often castrated badly.

if a function of the new iOS needs to rely on specific hardware, such as dual cameras for portrait mode and fingerprint module for Touch ID, it is understandable to castrate these functions on the old device. However, many new features of iOS are actually only related to software, or can be solved by software, but such new features are not standard for old devices, which is rather pit. For example, the iPhone 4 can't use Siri, but the player can actually run well after transplanting it after cracking it; For another example, the 3D Touch outbound shortcut menu can only be used by devices after the iPhone 6S, but in fact, the shortcut menu does not necessarily need pressure. For example, Android 6. provides a long-press outbound shortcut menu for all devices.

Android also implements the shortcut menu function by software. Why does iOS have to be castrated in old devices?

it's fine if you just cut out the new features, after all, the new machine depends on the new features as a selling point; However, if even the old functions are castrated, it is a bit too much. After upgrading iOS11, users of iPhone 6S and iPhone 7 found that the function of drawing multi-tasks from the edge of the screen with 3D Touch disappeared and became exclusive to iPhone X.. This triggered a large-scale protest from users. Although Apple added this function back later, it still made many users feel uncomfortable. Endurance after upgrade

Since Apple will limit CPU performance in the new iOS, does it mean that the new system will save more power? That's not true. Many users have found that after upgrading to the new iOS, the battery life has shrunk significantly, and even it has to be charged twice a day to be used normally. According to the investigation of enterprise data management company Wandera, the phenomenon of battery urine collapse after iOS upgrade has been further confirmed.

The survey shows that the battery life is obviously worse after upgrading iOS11

Wandera surveyed 5, iOS devices and found that the battery life of the same devices is obviously reduced after upgrading iOS11. Wandera selected the heavily used iOS equipment and the average used IOS equipment, and recorded the decay time of power consumption from 1% to %, which lasted for three days. The results showed that the decay time of iOS11 equipment was only 96 minutes, while it reached 24 minutes on iOS1, and the former was only 4% of the latter.

the iphone 6 should be regarded as a nail house.

this mobile phone was all the rage, and it is also the best-selling mobile phone in the iPhone.

this mobile phone uses A8 processor, and its performance is relatively strong, and it can still be used up to now, and its fluency is relatively sufficient. I think the most suitable system is actually iOS8. For us users, I don't recommend that you upgrade it to the latest version.

Although this mobile phone does have a relatively strong appearance design and grip experience.

today in 222, it is an old model after all, so I don't recommend upgrading it to the latest system, although it can't be upgraded to iOS14 or iOS15.

however, I don't recommend upgrading it to iOS11 system either, because the experience value brought by this system in the process of using the mobile phone is
