If you have an older generation iPhone, such as iPhone 3G or 3GS. You may notice, after 2-3 years of usage, that the OS runs sluggish and may even crash. Its well known that improvements and upgrades to the OS may allocate more memory, and having a nice little multitasking tool is nice. But its going to eat up memory fast.
Core Monitor (Free) is a nice little application for iPhone that lets you visualize current memory usage. As well as monitor:
- Remaining Battery (Roughly)
- Disk Usage
- CPU Load
- Running Processes
- Device Information (Slightly buggy in my experience)
In this tutorial I will show you how to shutdown multitasking threads, and how much memory it frees up. This may improve overall performance.
| 1. Download Core Monitor (Free) and Open It. You will be presented with current memory usage, in the form of a pie-chart. | |
| 2. Double-Tap the Home-Button to reveal the multitasking-bar. These are apps currently stalled in the background, populating memory-space. |  |
| 3. Tap and hold on any of the icons and release when they start moving. |  |
| 4. Start closing apps by taping the red markers. You can close all of them to free up as much memory possible, or ones you are not currently using. |  |
| 5. Tap the screen, returning to Core Monitor. Here you can see how much memory has been cleared. |  |
Did this improve your iPhone’s performance?
