Generally speaking, according to the stereotype of many people, the original original system version of iPhone is the best, and I thought so at that time, embarrassed.
One shuttle every year is the favorite part of the film tearing machine, tearing film, starting, activating, initializing settings and synchronizing data. After I finish, I will play happily with my new lover.
However, something unexpected happened. Not only does the gesture of sliding back to the desktop often get stuck, but the screen drops, and as long as it is turned on several times, applications such as WeChat in the background will be killed with a high probability. If you're playing the glory of the king, it's a disaster. Dude, you have to remember that you are Pro Max, 6GB of running memory!
The specific symptom of upward sliding is that the expected result of upward sliding gesture should be a quick response, and the smooth contraction animation can quickly return to the position of the App icon on the desktop and present a slight zoom effect, which is the basic level of the iOS animation factory.
But iOS 14. 1 obviously didn't do this. Not only did it pause about 1s after sliding up, but it also responded and returned to the desktop. In addition, there is an obvious frame loss phenomenon in animation, and the operation error phenomenon threatens the degree of user experience.
So at that time, my impression of iOS 14. 1 was very poor, and there was none, so don't say that the factory version is the best, and the difference is the difference.
Because there are too many version numbers in this interval, and in order to save everyone's precious time, I only mention some impressive ones, some good ones and some bad ones.
First, iOS 14. 1 was exposed to chip scheduling problems. In a word, it is a technical limitation to A 14 chip, and it can't run with full blood. I said why it's so stuck, but it's not my illusion!
Of course, this is another incomprehensible point. what is the purpose? This is iPhone 12 Pro Max, not an old machine!
Fortunately, after the push of iOS 14.2, the problems of operation delay and serious frame loss have been well solved, but it should be noted that only serious frame loss is still far from the silky 60 frames. However, it is undeniable that the battery life of this version is really shocking. 1% can last 10 minutes, which is easy to understand. After all, performance and endurance are like fish and bear's paw, and you can't have both.
The performance of iOS 14.3 has been initially improved, but it is still not warm enough and its endurance is slightly reduced. However, a moth was created, that is, the boot flash screen, but it did not affect the use. If you don't pay attention, you may not find it.
IOS 14.4 encountered a very strange problem, that is, one of my dual cards suddenly stopped using. I tried to switch the flight mode, but it didn't help to restore the network settings and restart, so I had to pull out the card slot and plug it in again.
For this problem, I especially doubt that it is the system version, because many of my previous system versions have not had similar situations for more than two months, but I stopped eating the next day after upgrading. The problem of no service signal is simply fatal, and the iPhone directly becomes an iPod.
Do you think this is over? No, no,no. This is just the beginning. After that, iOS 14.5 supported watches to unlock the iPhone, but it had nothing to do with most people. Although the fluency was improved, the "iPhoneの Signal Destruction Plan" was launched afterwards, which directly led to my almost missing the card the next day after the upgrade, and I installed it again and again. ......
The next important thing to mention is the fucking FX Xing IOS 14.5. 1. After upgrading, I feel that my iPhone 12 Pro Max is directly scrapped. I used it for two days, and it was stuck and hot. That's scalp numbness, doubt your life. As it turns out, even if you use the upgraded version of your new iPhone, please be cautious. If you don't do it, just GG. You can only say that the era of closing your eyes and upgrading iOS is a thing of the past.
A month later, iOS 14.6 was released, and it was written in the upgrade content, which solved the problem that the performance of iOS 14.5. 1 device might decrease during the startup process. In fact, I started to use it, and sure enough, the animation was smooth and the loading speed was fast by clicking on the app. It was a little hot when used a few days before the upgrade, but it will be fine in a few days, and the battery life is normal.
Another month later, iOS 14.7 was released, and I also upgraded. The fluency is basically ok, but the signal and battery life seem almost meaningless. After a few days of use, I still kept this view. IOS 14.7 often has disconnection problems under wifi, and the app is often blank. At first I thought it was a software and router problem, but later I found it was a system problem.
Compared with iOS 14.6, the network signal of iOS 14.7 drops obviously, and the fluency and animation effect are not smooth enough, but it can reach a stable and smooth level, and the battery life is really not so good. 1% of iOS 14.6 is 3 minutes longer than that of iOS 14.7, and the difference is slightly larger. It feels good to be back.
But I have to say that iOS 14.7 is indeed the coldest version. Don't like fever, don't care about the signal can be considered.
To evaluate a good system, I think it is stable, smooth (preferably silky), good signal, good battery life and no fever.
After this trip, I feel that iOS 14.6 is my most satisfactory system version, with only a little heat, and the rest have met my requirements, followed by iOS 14.2, iOS 14.4, iOS 14.5 and iOS 14.7. Their problem is that they are not good enough.
