When it comes to choosing electronic components for Internet of Things (IoT) applications, two important factors to consider are power budget and performance. Historically, there has always been a tradeoff between these two factors in electronic devices. Architects of these systems have unique requirements for each component based on the specific application. For instance, a high-performance controller may be necessary, but with a low-power memory, for wearable devices. This is because the controller needs to be powerful, whereas the SRAM is used for temporary storage. However, there are ways to improve memory optimization.


What is device memory?

When we say “memory”, we can mean both RAM and permanent memory inside the device. Both parameters are important. RAM is allocated for currently running processes, that is, it is used for applications and functions of the smartphone. Persistent memory – a memory where your data is stored permanently: photos, videos, files, etc. What is more important? All components are important but in their own way. We will look at ways to optimize both memory on a smartphone.

How to clear storage space on iPhone?

Why is this needed? If there is not enough memory on the device, the system will lag, and the smartphone may overheat and give errors. But after cleaning the loaded operating system, device efficiency, and even battery life will increase.

#1 Сlear the cache on an iPhone or iPad

Easily clear your Safari cache by following these quick steps:

1. Go to Settings and select Safari.

2. Scroll down and choose “Clear History and Website Data.”

3. Tap “Clear History and Data” to confirm. That’s it!

#2 Delete non-essential apps

If you have apps on your iPhone that you hardly use, they’re probably non-essential. You can easily identify and delete them by following these simple steps:

1. Open the Settings app.

2. Click on General.

3. Select iPhone Storage.

#3 Automatic cleaning

An easy and convenient way to free up space on your device is to use the CleanUp app Phone Cleaner. You can download Cleaner for iPhone from the official iTunes store. This is a smart cleaner that can free up space on your device by removing cache, temporary data, duplicate files, and similar junk files. In other words, you get rid of garbage, not useful data, and all this automatically.

How to clear memory on iPhone?

Clearing RAM memory is also important. Although the iPhone is able to maintain the desired level of free memory, it still starts to work more slowly when it drops. If your smartphone is running at high power, this means that the device will drain quickly and wear out the battery faster. But you can improve the situation.

Here is how you can clear RAM on your iPhone. If you’re using an iPhone without a physical Home button, you’ll need to enable AssistiveTouch to carry out certain actions.

  1. To do this, simply go to Settings > Accessibility > Touch > AssistiveTouch and toggle it on.
  2. A circular button will appear on your screen, providing you with a menu of touch options including the Home button. To access the Home button on newer iPhones, tap the circular button on your screen and select the Home option from the touch menu.
  3. To enter the shutdown menu, follow these steps: unlock your phone, press the volume up and down buttons in quick succession, and then hold the lock button until the shutdown menu appears.
  4. Once you’re on the shutdown menu, tap the AssistiveTouch button and long-press the Home option. It’s important to note that this is not the usual shutdown menu.
  5. Once you’ve cleared your RAM, a lock screen will appear. Enter your passcode and you’re good to go! To confirm that it worked, swipe up on the screen and hold it in the middle to access your App tray.


When it comes to optimizing the performance and battery life of mobile devices, memory optimization is a key component. By clearing storage space on an iPhone or iPad by deleting nonessential apps and clearing the cache, as well as clearing RAM memory through AssistiveTouch, you can improve device efficiency and extend battery life. All these steps together will help your device run smoothly.
