All of us have heard of RAM. Quoting Wikipedia, Random-access memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed directly in any random order. RAM is the most important part of any device. It holds key to the speed of your device. So, before going on to the “speeding up” part, let us understand about iOS RAM.
How does iOS RAM function?
Unlike the RAM of our computers and many other devices, iOS RAM functions very differently. Windows puts active applications in memory until they are no longer active or you run out of memory, in which case it goes to a swap file. iOS keeps as many things as possible in memory for quick loading times. When it runs low, it will kick some stuff from memory. This allows iOS to go as quickly as it does. In simpler words – in Windows, having more Free RAM(RAM that has been freed by killing the running applications/services) is good, as it can be put to use on other applications and services. However, iOS treats free RAM as wasted RAM. So, you’re actually wasting potential. iOS is designed to take RAM from other processes when it needs it, so you need not kill apps manually. Free RAM is not contributing to the performance of the system because, well, it’s not being used.
NOTE -> When I say killing apps, I mean closing apps/processes in any way.
Now, to the main part.
How to Speed up jailbroken iPhones or iPads?
The speed of your iPhone or iPad depends on RAM. If you are facing speed issues, then it’s probably because your hardware is outdated, or you have free RAM. If you are using old devices like iPod touch 4, then your speed issue is because of limited hardware. In that case, consider purchasing a better device.
Also, now that you have understood the functioning of iOS RAM, STOP KILLING APPLICATIONS. Free RAM is wasted RAM. Just let iOS do it’s work. It can automatically take up memory from other processes, which is good. If SBSettings shows you less Free memory, consider it as a good sign. The more free memory you have, the lesser the speed of your iDevice.
You can try using lesser tweaks from Cydia and make sure you do not have any malware affecting your iDevice.
Alternatively, you can use iCleaner(a free tweak from Cydia). This tweak can improve the device performance by clearing your log files, temp files, cache files, browser history and other crappy data which eat up your device storage.
Using iCleaner once or twice a week is a good way to clear unwanted stuff from your device.
