IOS 11 officially on the line for half a month, in these ten days, iOS 11 installation rate has reached 38.5%. Compared with the two week installation rate of iOS 10, iOS 11 is lower (relative to the upgrade rate of any new version of Android). But in the apple related forums, including our winmark forum, you will find that in fact many users to upgrade iOS 11 after the brush back to iOS 10.3.3, while another part of the users may still waiting, waiting for iOS 11 upgrade to more stable.
Although iOS 11 brings a lot of UI updates and new functions, but some of the problems still allow users to hesitate and dare not upgrade casually. This paper will search Weifeng forum with Apple's official forum users reflect, summarizes some common problems of the iOS 11 upgrade, not everyone will encounter these problems, according to the different models and different equipment. Now iOS 10.3.3 and iOS 11 have been shut down and verified, we have not downgraded back to iOS 10.3.3 this road can go. Therefore, this paper will make some useful suggestions for these problems.
upgrade power consumption of 11 iOS power consumption problem is often linked to the mouth, or say, almost every new version after the upgrade system are more or less people to reflect the power consumption problem. That's because the new version of the system needs several charging cycles to recalibrate the battery charging mechanism, for example, Spotlight needs to complete all the files on the retrieval device. However, the new version seems to have more complaints than ever before, and there are still many complaints after two weeks of publication. IPhone 8 and iPhone 8 Plus native iOS 11 system in the evaluation found that the battery life is normal, that is because iPhone 8 and iPhone 8 Plus have A11 bionic chip for escort.
, a company called wandera enterprise security solutions provider in a recent survey, they looked at 50 thousand iPhone and iPad of the moderate and severe user battery average attenuation rate, compared with the last three days were upgraded iOS 11 and iOS 10 retains the device's battery decay rate.
found that, from full power to full electricity, iOS 11 continued to use for 96 minutes, and iOS 10 continued to use for 240 minutes. Even so, wandera suggests that their business customers better not downgrade back to iOS 10.3.3, because the latest version has a higher degree of protection for equipment, personal and enterprise data sets. Since
can't be relegated to iOS 10.3.3, we can only improve the power consumption elsewhere.
first made a rough little test to see whether the background secretly depreciation program. Go to settings - the current standby battery "a few long and long use, and then close the screen for 5 minutes. 5 minutes after the re check the battery usage, if the standby time that increased to 5 minutes, but the use of the same length, it can be roughly estimated to have secretly depreciation program background. But if you use longer, that adds more than 1 minutes longer, then you should pay attention to the background program.
although we have developed a background program without closing the habit, but had to admit, some App indeed secretly not system, leakage of electricity, but the problem of App. If you find a App is not in use, but still power consumption, that is a problem. For example, the author had encountered the Exchange mailbox push it into an infinite loop problem caused iPhone can not take "rest" standby, automatic push into manual push or every 15 to 30 minutes to push once can be solved. You'd better do all of the mailbox accounts.
is one of the most popular ways to make proper adjustments to some App. It is not that you fear, not that we can completely uninstall what the power consumption of App. Instead, some App don't have to make them refreshed in the background, and we can selectively close them. Another option is to allow background updates only under Wi-Fi conditions, because the power consumption on the 4G network is much faster than that under Wi-Fi. But the better thing is that you can default on background updates in Wi-Fi and cellular networks, but selectively open the background refresh for your own App.
in distress situation can also open the settings - battery - low power mode ", but this is not recommended when necessary to open, otherwise iPhone will disable mail access, hey Siri, all background applications refresh and automatically download, this is equivalent to some function of castration.
sometimes finds that deleting a power hungry App and reloading it, restarting iPhone, can occasionally cope with power consumption problems.
said the power we often hear the advice is to turn off location services and Bluetooth function, but in the actual use of the frequency of use of these two items is very high, such as the Apple Watch users could not close the bluetooth. And now many App use location services, such as a takeaway, map navigation, riding a shared bike, switch on every day, positioning service is also very troublesome.
"up wake-up" is a very convenient function, but in order to save the power point, it is recommended to shut this function, otherwise iPhone may often wake up the screen in the pocket, although the power consumption is not large. Apple Watch users do not need to open this function, see the time to see the news, you can directly lift wrist watch watch on the line.
upgrade iOS 11 users, there are still a small part of the problem of overheating equipment. Usually, when you use some App, there will be obvious fever, for example, when playing AR games, if the equipment is too hot, App will automatically shut down.
if you feel abnormal heating equipment, you can turn off location services, because the location will continue to search GPS, Bluetooth, signal tower to determine your position, which makes the iPhone
