The last version of iOS 14.4. 1, my personal experience (iPhone 1 1), is mainly that the signal is average and the battery life is poor, but after upgrading iOS 14.4.2, the fever and battery life have been obviously improved.
Netizen A: Apple 7' s new battery, the system watches video fever under 14.4. 1 system, it takes 4.5 hours to turn it off when it is fully charged, and the standby power consumption is also 0 to 8.7%; 14.4.2 system, when fully charged, standby power consumption is 5% from 0: 00 to 8: 00. At 8: 00, I started to use WeChat, brush and paste, watch Li Li, read novels for 3 hours and 49 minutes, and still have 5% power. I don't have a fever when watching videos.
Netizen B: 14.4.2 This version, if the fever is abnormal or the APP is stuck, it is recommended to brush the DFU mode again, set it as a new mobile phone, and reinstall the software one by one. It is found that fluency, fever, battery life and other aspects have been improved, which should be the best in the current 14 system and can support the elderly. OTA upgrade effect is not as good as DFU, it is not metaphysics, it is practical experience, and it is not explained. My model is 8P;
Netizen C: This system consumes a lot of electricity, and people who say that they don't consume electricity are fooling people. In terms of speakers, the effect of playing music is not as good as before. This is not obvious, and the signal problem is not as good as before. The same is true in other aspects. There is no difference. The only good thing is that there is no flashback in the background.
Netizen d: power 100 to 99. Brush Tik Tok 16 minutes, for reference only! The model is xs;
Netizen e: iPhone 12. I charged it at 6 am and listened to novels all day. It's been a day, and there's still 62%. IOS 14.4.2 is ready to retire.
Summary: Generally speaking, netizens are satisfied with the overall upgrade of iOS 14.4.2. Of course, some models or some mobile phones have problems during the upgrade process.
But if you are already a user who has upgraded to iOS 14, this time iOS 14.4.2 is worth upgrading. If you haven't upgraded iOS 14, you can wait. The upcoming iOS 14.5 may be even better.
