Apple has been releasing the official version of iOS 16 for nearly two weeks. There are too many bugs in iOS 16 this time. After upgrading, it cannot be downgraded, and the old models dare not upgrade.
I remember that in the previous beta version, many students reported after upgrading that they encountered problems such as lag, fever, rapid power outage, and incomplete text. For example, before the official version was released, after the upgrade of iPhone 12 Pro Max, the lock screen interface was stuck, and the problem of being unable to set wallpapers and WeChat crashes...
(the temperature prompts for excessive voice calls on iPhone 12 Pro Max)
. After the official version arrived, I found that many problems were still not solved. There are still quite a lot of errors, bugs, performance problems, battery consumption, etc.
For example, the camera shake problem and copy and paste prompts that occurred two days ago were fixed by Apple's emergency release of iOS 16.0.2.
Although there are currently two versions of iOS 16.0 and iOS 16.0.2, many users still face several unsolved errors. Here I will summarize it based on the problems encountered by everyone on the Internet:
- Spotlight Search sometimes does not work properly
- Excessive and abnormal battery consumption
- After the update part of iPhone display screen flashes black spots at low brightness
- …
If you encounter other problems after upgrading to iOS 16, remember to leave a message in the comment area.
As for students who encounter problems, Apple usually recommends that you restart iPhone to solve the problem, but it can only be said that it is a treatment of symptoms but not the root cause. There is no sign of iOS 16.0.3 yet, so it is not clear whether Apple plans to update iOS 16 before the release of iOS 16.1 next month.
If you want to downgrade, you can only downgrade to iOS 16.0 at present, and the rest of the channels Apple has been closed. After the new version of
iOS is released, Apple will regularly close the verification channel of the previous version to encourage users to upgrade.
However, if you are in iOS 16.1 Beta 2, you can consider downgrading first.
is downgraded from the higher version to the lower version, and the data cannot be retained. The backup under iOS 16 is not universal in iOS 15, so you must backup it before downgrading.
Note: Do not use the "protect information flash" function of tools such as IS Assistant. There is a high probability that white apple will occur. Once it occurs, not only will the data not be protected, but it will also be more troublesome to flash the machine.

, be careful to turn off "Find My iPhone", otherwise once you forget your ID and password, your phone will become a brick.
Then enter the iPhone into DFU mode. The method is as follows:
After turning off the iPhone, connect iTunes, and press and hold the power key and the volume-key at the same time for about 10 seconds. When the screen starts to black screen, release the power key and continue to hold the volume-key.
or use Aisi Assistant to enter DFU mode with one click. After the download is completed, connect to iTunes. The Windows system holds Shift on the keyboard while clicking the update with the mouse. Then find the update package you just downloaded on the computer desktop and start updating;
Mac system holds the Option on the keyboard, clicking the update with the mouse, select the update package you just downloaded, and then wait patiently for the update to complete.
It should be noted that when your iPhone enters recovery mode, the data on your previous phone may be cleared, so no matter what kind of operations you want to do with your iPhone, remember to back up first!
⚠️: Whether it is an upgrade or a downgrade, you must backup!
Due to the bug problem of iOS16, Apple urgently pushed the iOS16.0.2 version update to everyone last Friday. Although iOS16.0.2 is just an upgrade to fix the error urgently, Apple seems to be sincere: not only reduces the copy-paste pop-up window, but also optimizes the battery life of some models and other problems, bringing full optimization.
Apple highly recommends that iPhone11 and future models upgrade iOS16.0.2 users. How about the experience of upgrading iOS16.0.2 for old models such as iPhoneX? Should the old models be upgraded to the official version of iOS16.0.2?
Test model: iPhone X
Test system: iOS 15.7 to iOS 16.0.2
1: Fluency
Through test comparison, it was found that the smoothness improvement of iPhone X after upgrading from iOS 15.7 to iOS 16.0.2 is particularly obvious. The system slides smoothly under daily use, and the sliding in the APP is also silky, and there is almost no lag.
2: Battery life
has been upgraded to iOS 16.0.2, iPhone X battery life has also ushered in a wave of improvement.
You should know that before iOS 15.7 consumed 4-5% of the power per night, and after upgrading, it consumed only 3% of the power per night. This is very rare for old models to have such a performance. The iPhone X is fully charged on iOS 15.7 and has 32% remaining battery life test after 3 hours of moderate battery life test, while the remaining battery life test in iOS 16.0.2 is 37%. The battery life improvement is still very obvious, which can alleviate battery life anxiety.
3: In terms of signal
signal performance, iPhone X can maintain 3-4 grids of signals in iOS 15.7 most of the time in outdoor scenarios, and only 1 grid or no signal in the elevator. After upgrading to iOS 16.0.2, the signal will be improved. In outdoor scenarios, the signal is basically full grids, the elevator signal can be maintained at about 2 grids, and the network speed is faster, and the delay in playing games on 4G network is lower.
4: Heating
In terms of heating, the dual-layer motherboard that everyone is familiar with iPhone X is not good in cooling itself. Thanks to the excellent optimization performance of iOS 16.0.2, the system not only maintains smooth running speed but also reduces the heat generation. Whether it is daily use or playing games, it is cooler than iOS 15.7.
Through testing and comparison, we found that iOS 16.0.2 is optimized very well, which can make the old iPhone X models perform better than the previous iOS 15.7 in terms of battery life, signal, fluency, heating, etc. As we suggested before, before upgrading to the official version of iOS 16.0.2, please pay attention to backing up your mobile phone information! After upgrading, you cannot downgrade, as downgrades may risk losing data.
