[周刊王CTWANT] Apple officially launched the latest iOS 17.4.1 system on the 22nd. After testing by foreign Youtubers, it was found that if the iPhone SE and iPhone 13 use iOS 17.4.1, the battery life will be improved, but if it is the iPhone 11, iPhone 12, iPhone 15 If you wait for the model, the power consumption will increase and the battery life will decrease significantly. But if you have upgraded to iOS 17.4.1 and want to downgrade, you can currently choose to downgrade back to iOS 17.4.
According to the test of the foreign YouTube channel “iAppleBytes”, the battery life of iOS 17.4.1 is as follows:
iPhone SE (2020 version): 3 hours, 33 minutes
iPhone XR: 5 hours 11 minutes
iPhone 11: 4 hours 58 minutes
iPhone 12: 5 hours 50 minutes
iPhone 13: 6 hours and 40 minutes
iPhone 15: 10 hours and 22 minutes

But if based on the power test video of “iAppleBytes” that previously tested iOS 17.4, the battery life results at that time were as follows:
iPhone SE (2020 version): 3 hours and 19 minutes (14 minutes more)
iPhone XR: 4 hours 44 minutes (reduce27 points)
iPhone 11: 5 hours 26 minutes (reduce28 points)
iPhone 12: 5 hours 59 minutes (reduce9 points)
iPhone 13: 5 hours, 48 minutes (52 minutes more)
iPhone 15: 10 hours 47 minutes (reduce25 points)

From a comparison, it can be clearly seen that except for iPhone SE and iPhone 13, which have increased battery life after upgrading to iOS 17.4.1, the other models have reduced battery life by at least 10%. Among them, iPhone XR, iPhone 11 and iPhone 15 have experienced a greater decline in battery life. Amazing, almost half an hour
“CTWANT” recommends that if users have not upgraded to iOS 17.4.1 system, they can consider whether to upgrade (but at least upgrade to iOS 17.1, because there are very fatal security vulnerabilities before iOS 17.1). If you have upgraded to iOS 17.4.1, you still have the opportunity to restore it to iOS 17.4. But in the past, Apple would be used to turning off the authentication function of the old version of the system one week after the launch of the new version of the system, so if you want to downgrade the version, you really have to be quick.
