1, the beginning to say the key point, iOS13 official version is not worth upgrading ios14.3 wireless charge off! The reasons are as follows: The official version of iOS13 does not solve the "green screen gate" event of iPhone 12ios14.3 wireless charge . At that time, according to Apple's official statement that the system problem of the green screen door can be fixed through the system update, but the official version of iOS13 did not fix this problem. 2, in fact, some iPhone users dare not or are unwilling to upgrade iOS13 system, mainly for two reasons: first, worry about the updated iPhone in terms of battery life "urine avalanche"The situation. Second, I am afraid that the iPhone running after upgrading iOS13 will be stuck. Frankly, these two things are the "heart" of most iPhone users. 3. To sum up, Apple version 13 performs well in terms of operating system stability and performance, but it is relatively conservative in terms of features and user experience, and there are certain problems in terms of battery life. For the majority of users, this version is still a worthwhile upgrade option, but for users looking for novelty and innovation, other more innovative options may need to be considered.
4, look at the phone model, if it is iPhone8 or before the model, it is not recommended to update iOS14, if it is a later model, it is recommended to update. iOS 13 is the third major update of ios 14 since it went live in September, and the new system brings some new features, while focusing on fixing some system bugs. iOS 13 added a dedicated "Original" TAB. Apple has introduced a new TAB in the TV app.
Good iOS firmware version has been updated to 13, from its update description, and did not make upgrades to the green screen problem and abnormal battery power consumption, but to the MagSafe wireless charging function, AirPodsMax headset and iPhone12Pro RAW photo shooting made upgrades, But these upgrades really don't mean much to the average user.
Take the iPhone 7 Plus with IOS13 as an example, the application in the mobile phone has a flash back phenomenon, which indicates that the application is incompatible with the system. This situation generally occurs in the applicationNot a regular application. This means that an App is installed through a trust description file, and such an app is not listed in the App Store because it is incompatible with iOS or does not have the required security level.
Not recommended, most functions on iOS15 are not available. This version of iOS18 is already suitable for the elderly, and then the mobile phone chip feels immovable. I do not know whether it is OK to downgrade the mobile phone system after watchOS 8, if you can, you should operate as soon as possible, because Apple has closed the verification of iOS 11 this Monday, which is not allowedUser demoted.
First charge the ipad (preferably full), as shown in the image below. Then press and hold the power button (the ipad power button is in the upper right corner), as shown in the image below. Release the power button until the screen lights up, as shown in the image below.
But have to say, iOS17 is indeed the coldest version, do not like heat and do not care about the signal can be considered. I think the criteria for evaluating a good system are stable, smooth (preferably silky), good signal, good battery life, and no heat.
1, better than 12 endurance. The first thing to say is that the official version of iOS13 did consume power when it was just updated, and was accompanied by a certain amount of heat, which is also a normal phenomenon of new system updates. In the light experience for a few hours, basically compared with the previous RC2 version, the battery life time is roughly the same, at least there will be no battery crash and problems such as stuck.
2, IIs iphone7-32GB, just upgraded from 12 to 13 two days ago, the improvement is obvious, 13 does not kill the background, the battery life also feels improved some, other aspects of the difference is not big, anyway, I was 12 experience is very bad, in addition to kill the background, poor battery life, the phone also began to lag, now upgraded iOS13, much more stable, I'm planning on using this version for retirement.
3, similar to the model used for 5 years, in fact, the upgrade to 13 is almost, the upgrade to 14 is still a little reluctant. If nothing happens, it is estimated that iOS15 is not supported. In fact mostIn this case, even if we do not upgrade the system, the iPhone can be used normally without any obstacles.
4, however, it is worth mentioning that although iOS14 is very good to use, but this kind of iPhone is best not to upgrade, otherwise there may be a "pop-up warning". It is reported that Apple added a feature in iOS14 to "detect whether the iPhone lens is original", and will give a "pop-up warning" for those iphones that have repaired the lens.
5, the app resource library of Apple mobile phone needs to be upgraded to iOS14 system before it can be enabled
