It is not that the iPhone never hangs but it is very low compared to other platforms (like Android).
Since this topic is technical, first I would like to introduce you with a few words -
UI Rendering - The primary function of a mobile graphics processing unit is to process the data on the screen and this is broadly called rendering.
Thread - Whenever an application is launched in Android, it creates the first thread of execution, known as the "main" thread. A main or main thread is a carrier that sends all events to the UI and establishes communication with all electronic components.
Let's talk about Android first -
Why does android hang
If we talk about Android 3.0 means Honeycomb, then there was no hardware acceleration in UI (user interface) at that time means slow process and hang problem. But if we talk today, Android has more RAM (more than 2 GB) than iOS, then what can be the problem at this time.
The main reasons for this are -
UI rendering is given a normal priority in Android (as compared to iOS).
UI rendering is done using the main thread. This means that at the moment all your processes in the background will remain operational due to which there will be lag.
Even if you have a quad or octa core processor, this happens because of the 2 reasons mentioned above.
But if everyone knows this, then why not change the basic structure of this type of Android UI so that this problem does not come. But this is not so easy because all Android apps will have to be re-coding for this. Today, there are millions of Android apps and new ones are coming every day, so this is very difficult.
Some other reasons -
Heavy apps put a lot of pressure on the processor and internal memory of Android phones, including pre-loaded bloatware.
Widgets and unnecessary features are present in the Android system.
Since Android has internal and external memory and many users use internal memory to save everything. So it starts lagging over time.
Keeping a lot of apps open in the background at once, especially games, browser and Facebook.
Download apps from unverified source.
Do not update software periodically.
why ios doesn't hang
Now see how i Phone has changed things -
iPhone has given a separate (dedicated) thread for UI rendering. It has no meaning with the main thread. This also makes the processes running in the background run like butter.
UI rendering is given high priority here.
It sends the combined power of CPU and GPU to handle UI interphase. This results in less lag.
Perfect software and hardware integration |
Using Instant Internal Flash Storage
Provision of strict restrictions for apps that use excessive phone resources.
Better security than Android and less flaws.
No place for pre-loaded bloatware.
Third-party apps have little to no problems with viruses or spyware.
What to do for Android so that it does not hang.
When you run multiple applications at the same time, your mobile hangs automatically. Make sure to use only one application at a time or else your mobile will start to heat up and hang.
Be sure to periodically remove unnecessary applications, photos or videos from internal memory.
Save all applications, videos and photos to memory card (SD card) and not to internal memory.
Move many installed applications to external memory. Apps also come for this.
Manage your files and remember to delete unnecessary files, cookies and cache etc. from time to time. You can use cc cleaner.
Close the applications that have been opened in between.
Keep updating the software regularly.
Understand the specs of your phone, such as what processor my phone has and how much RAM it has. Install apps and games accordingly.
