How to make the old iPhone running iOS11 system smoother

It's easy to fix this problem, especially since iOS 11 also offers a lot of foolish cleanup solutions. You can browse the usage of your phone's capacity in the Settings -> General -> iPhone Storage option. In addition to deleting data from individual apps (or simply deleting apps), you can also uninstall unused apps or enable iCloud Gallery, which can easily save a lot of space.

2.Enable the HEIF HEVC compression format.

The HEIF format is a compression method only available in iOS 11, while the video is HEVC. For people who usually like to take a lot of photos, even if they use iCloud** Library, they will feel that the space is not enough, so enabling the HEIF format can save a lot of space. The setting method is:

Settings -> Camera -> Format in the High Efficiency option.

3.Update the app.

Some old apps may slow down the system (especially 32-bit apps that are not supported by iOS 11), so update all apps as soon as you update them to iOS 11.

Like previous versions of iOS, iOS 11 will run many apps silently in the background, such as automatically updating all apps. Updating apps in the background is a CPU and memory hungry service, so turning it off can make the phone less loaded, especially for old iPhones, and turn off these non-essential functions as much as possible.

5.Reduce dynamic effects.

Motion effects are designed for beautiful special effects on iOS, such as returning to the home page, switching apps, etc. While motion effects can make the user enjoy a better experience, for older iPhones, these effects are the main culprits on the phone, and turning off motion effects (which doesn't affect the use anyway) can make the phone a little smoother.

To turn off motion effects, turn the Settings -> General -> Assistive Use ->Reduce Motion Effects option. In addition, you can also enable Reduce Transparency and Burn Color under the Increase Contrast option above, which will increase the legibility of the text and reduce the burden on the processor.

6.Choose your GPS positioning settings carefully.

Strictly speaking, GPS service is not a big load on the system, but it is a big burden on the battery, especially the battery of an old iPhone often can't last a day.

In Settings -> Privacy -> Location Services options, you can set individual apps to change the rarely used app GPS option to "While using the app", or simply select Always let the app disable the GPS service.

Method steps.

The HEIF format can be smaller in size and lossless in image quality And when sending**, the iPhone will automatically convert the **format into a format that the other party can recognize! There's no need to worry about compatibility with new formats**!

1.Upgrade to.

Some of the changes included should help improve the overall performance of the iPhone 4 and 4S. If you haven't already, we strongly recommend that you upgrade your system to.

2.Turn off background app refresh.

iOS 7 brings a new feature called Background App Refresh. While it allows apps to do cool things like refresh app content in the background with minimal battery usage, your iPhone still needs to keep these processes running. The best option for iPhone 4 and 4S users is to turn off all background app refreshes, but the system also supports individual controls for each app.

3.Reduce transparency and dynamics.

Although the iPhone 4 does not support the parallax effect, the 4S does. Luckily, you can turn off motion and transparency. These two options can help reduce the amount of graphics resources required and help speed up system navigation.

It's important to note that the option to turn off transparency was added for the first time, so you'll need to upgrade your system to that version to turn it off.

4.Reset all settings and keyboard dictionaries.

The biggest complaint that users have about iOS 7, especially with the iPhone 4, is the lag of the keyboard. In some cases, resetting the general settings and keyboard dictionary can alleviate the problem somewhat. If you have the emoji keyboard turned on, it's a good idea to turn it off as well.

5.Recovery and purge.

If none of the above methods can speed up your device, it's worth restoring and erasing your device. First, you can try removing apps that don't work.

However, in some cases, iOS 7 may allow some users to fill up all the storage space on their devices, which can cause many strange things to happen, one of which is latency. You can check how much storage you have left on your device in the Settings app, and if you don't think that's all you need, you can try a restore on iTunes to free up space occupied by junk files.
