How Can I Fix My iPhone Running Slowly?

In today's era of rapid technological development, Apple's iPhone has become a favorite of many users with its excellent performance and smooth experience. However, many people will find that as the use time increases, the iPhone gradually becomes slower and slower, which seriously affects the daily use experience. Whether it is the long wait when opening the App or the freeze when sliding the screen, it is very annoying. Don't worry, if you are also troubled by the problem of iPhone running slowly, then this article is your "savior". Next, Phonefix Company will deeply analyze the reasons why the iPhone runs slowly, and share a series of practical and effective solutions to help your phone regain its vitality and restore its former smoothness.

iPhone Official Solutions:
Check the network status ​

Many applications rely on the network to obtain content and implement specific functions. When the network you are connected to is congested, such as at a crowded event site where a large number of users are using the same network at the same time, it will take a long time for the application to open or load content. In addition, when you are in a moving vehicle, the device is constantly reconnecting to new signal base stations, which can also make the phone seem to be running slowly. ​

Even if the device shows that the signal is good, sometimes you need to wait patiently, or try again in another place, or connect to an available Wi-Fi network. If there are continuous problems with cellular data speed, availability, or performance in multiple locations, it is recommended to contact the operator to resolve the problem. ​

Close unresponsive applications ​

If an application stops responding or freezes, you may need to force close it and reopen it. ​

1. The operation path varies depending on the model: On iPhone X and later models or iPad, swipe up from the bottom of the home screen and pause in the middle of the screen; on iPhone 8 and earlier models, double-click the home button to bring up the list of recently used applications. ​

2. Locate the target application: Swipe left or right on the screen to find the application you want to close.​

3. Perform the close operation: Swipe up the app preview window to close the app. ​

It should be noted that under normal circumstances, force closing an app is not only unnecessary, but also does not improve the device's running speed. In fact, after force closing, the app needs to reload all data, which will make it take longer to open it next time. ​

Ensure sufficient storage space ​

When the device storage space is insufficient, iOS or iPadOS will automatically free up space when installing apps, updating the system, downloading music, recording videos, etc. The system will only delete files that can be re-downloaded or are no longer needed. You can view the storage status of your device in "Settings" > "General" > "[Device] Storage". For optimal performance, try to keep at least 1GB of free space. If the available storage space is less than 1GB for a long time, iOS or iPadOS will frequently clear space, causing the device to run slower. 

If you need to free up space, follow these steps to enable the built-in storage optimization suggestions in iOS or iPadOS:​

1. Go to Settings > General > [Device] Storage to view the optimization suggestions given by the system. ​

2. Tap Enable to turn on a suggestion, or tap the suggestion title to see what can be deleted.

​After tapping an app, there are two ways to free up space:​

Uninstall the app: You can free up the storage space occupied by the app, but keep its documents and data. ​
Delete the app: This will delete the app and its related data at the same time. ​

Note: Some apps also support direct deletion of some of their internal documents and data. ​

Turn off Low Power Mode​

Low Power Mode is a useful feature of iPhone and iPad that extends battery life by reducing device power consumption. In this mode, some features will be turned off and some tasks will take longer to complete. When the iPhone Battery icon is yellow, it means that Low Power Mode is on. If you need your device to not be restricted by low power consumption, you can consider turning off this mode. You can do this in Settings > Battery.​

Avoid overheating or overcooling your device​

When the device is exposed to high ambient temperature, such as being placed in a hot car or in direct sunlight for a long time, iOS or iPadOS will automatically adjust the device's performance. At this time, you need to move the device to a cooler place to let its temperature return to normal. Similarly, extremely low temperatures can affect the speed of the device. If the device runs slowly in a cold environment, it should be moved to a warm environment. ​

Check the battery health

All rechargeable batteries are consumable parts. As time goes by, their chemical properties gradually deteriorate and their efficiency will also decrease. Over time, the battery capacity and peak performance of iPhone and iPad will decrease, and eventually need to be replaced. The iOS system can check the battery health and prompt whether the battery needs to be replaced. Go to "Settings" > "Battery" and tap "Battery Health" to view relevant information. Please note that this feature is only available on iPhone.

DIY Solutions:

I. DIY diagnosis of network status

Simple network test: Open the browser that comes with the phone and visit the commonly used websites. If it loads slowly, try to switch to other websites to determine whether it is a problem with a single website. You can also use the speed test app to carefully check the upload and download speeds of the current network. If you are in a large shopping mall, concert or other network short-term area, diabetes moves to a corner or open space to reduce co-frequency interference and improve network connection stability.

Reset network settings: Find "General" in "Settings", click "Restore", and select "Restore Network Settings". This operation can clear all saved Wi-Fi passwords and network settings, and then you need to reconnect to the network, but it can effectively solve the problem of freezing caused by some network abnormalities.

II. Unresponsive application "First Aid"

Clever use of Catholic shutdown: According to the operation method of the previous bracket, after calling up the corresponding interface of application switching, use multiple fingers to close multiple unresponsive applications at the same time to save operation time.

Avoid misoperation: To prevent the next application from accidentally freezing, try to avoid opening too many applications at the same time during daily use, and regularly close unnecessary programs in the background.​

III. Free up storage space autonomously​

Photo and video cleaning: Open the "Photos" application and use the "Recently Deleted" folder in the "Album" to completely delete photos and videos that are no longer needed. For 4K videos that occupy more space, you can transfer them to a computer or cloud disk, and then delete the original files in your phone. ​

Chat history slimming: In social apps, enter the settings of the chat window and choose to clear chat history to free up a lot of cache space. Taking WeChat as an example, you can also deep clean up chat history in "Settings"-"General"-"WeChat Storage Space" and selectively delete large files and caches. ​

IV. Low-Perception Mode Intelligent Management​

Personalized Opening: Develop the habit of checking the battery level. When the battery level is 20%-30%, decide whether to turn on the low-power mode based on current needs. For example, if you need to use navigation in an emergency, turn off the low-power moment mode in advance, and the navigation function will run normally. ​

Scenario settings: With the help of the shortcut command app, create automated tasks, such as automatically turning on the low-power mode when the battery level is less than 20%, and turning off some unnecessary adaptive notifications to achieve intelligent management of the low-power mode.​

V. Self-regulation of device temperature ​

Evaporation tips: When the device heats up due to long-term gaming or charging, pick up the phone case and place it flat on a cool, ventilated surface, such as a marble tabletop. You can also use a small fan to blow on the phone to accelerate evaporation.

Warmth measures: In the cold outdoors, you can put the phone in your pocket to keep the device running normally with the help of human body temperature to avoid freezing caused by low temperatures. ​

VI. DIY maintenance of healthy batteries ​

Optimize charging habits: Avoid overcharging and over-discharging, and first charge between 20% and 80% of the remaining power. Use the Original Charger and Data Cable to reduce damage to the battery by non-formal accessories. ​

Monitor battery health: Follow the previous text to check the battery health regularly. When the maximum capacity of the battery is found to be less than 80%, consider replacing the battery. You can purchase a regular battery replacement kit and replace the battery yourself according to the online tutorial to save repair costs.
