#Tell the truth#Foreword: Apple mobile phone system With the release of iphone15 series mobile phones, the ios17 system has come, and the latest version of the system is ios17.2.1 version. But after the fans upgraded to the iOS17 system, the response was strong, and the controversy was great, and I felt that the system optimization of this version was not very good, except for adding some new features that were not practical, I always felt that there was some negative optimization. Apple has also seen a lot of feedback from everyone, and is constantly tinkering and optimizing the version system. This is why Apple frequently updates and upgrades the iOS 17 system.
Today, the question that everyone always asks, that is, the ios16 system is better than the ios17 system, and the question of whether to upgrade, focus on my actual test feedback to you, maybe you don't have to worry about whether to upgrade to the ios17 system. I'm talking about the following series models here, because the 15 series mobile phones are released as ios17 system, and they will be upgraded directly if there is an update.
In terms of battery life, I want to say that no matter what model of mobile phone you have, from the iOS16 system to the iOS17 system, the battery life has decreased (except for the 11 series of individual phones), but the amplitude is different. The maximum drop can reach an hour and a half, and the smaller one is about 20 minutes.
1、14 series mobile phones are not generation-skipping mobile phones,The decline is slightly smaller,You can try to upgrade the ios17 system in a better version,At present, the best comprehensive version is ios17.1.2,The best version of battery life is ios17.0.3 version system。
2. The version with the best battery life of the 13 series mobile phone should be ios16.5 and ios16.6.1 version systems. Upgrade to iOS17 system, no matter which version of the system, the battery life will drop by more than 1 hour, after all, it is the next-generation version.
3. The best version of the 12 series is the ios16.5.1 version system, and when you upgrade to the ios17 system, the decline is even more obvious, reaching a maximum of more than 1.5 hours.
4. 11 series mobile phones in the ios16 system, the best version of battery life should be ios16.3 system, upgrade to 17 system, battery life rises and falls, especially upgrade to the 17.0.3 version of the system battery life is improved, the range is not large, in about 13 minutes.
Conclusion: The above is my feedback on the comparison of the battery life performance of the 14 and below models in the iOS16 and iOS17 systems, for users who are still in the iOS16 system, I do not recommend upgrading to the iOS17 system, the fluency is improved, but the battery life is sacrificed in exchange. After all, there will be problems with the compatibility of the hardware and the new system for the next generation, leading to different results. Hope it helps.
