These Could Be Slowing Down Your Old Mobile Phone

I am back to my old Samsung S3 when I lost the Note 3 late last month. The S3 was my reliable mobile phone 4 years ago and handed it down to my son for 2 years. It's operating system remained unchanged as the latest JellyBean variant 4.3 and can still handle the basic of calls, text messages and internet based messaging. The only thing that I annoys me is it is very slow to respond on touches. Sometimes it takes at least 10 seconds to show the dialer window when I want to make a call. The same with the camera, it takes sometime before it is ready to take a shot. The native messaging application makes the screen black and sometimes it does not recover so I am forced to restart the phone by pressing the on/off button and it I am not patient, I take off and put on the battery to speed the restart process. It is not only the the messaging application  that's making this thing happen, but all application has their own moments to turn off the device.

 Whatever is happening these things come to mind causing the havoc.

1. Too much item is in the cache.
2. Apps hogging on resources
3. The processor can not cope up with the application demand.

To address these problems, I need some free tools to help me and make the old phone at least a second chance to be of service.

Delete the cache.

Cache are pieces of information  that the mobile device copies from the web you are visiting for faster loading in case you visit the same page in the future again. But like computers, these data could be outdated and no longer  relevant. And this causes the problem that can cause the browser stops working.

Applications do the same as well, they start collecting and saving files for later reference, for that application to show where you left up the last time you use it. It can really save you data, but it can also be corrupted causing problems.

It is not only the corrupt cache file that becomes the problem but the amount of  space that it is occupying.

There is a built in tool to delete the cache by going to the application information. But if you are talking about  every application, then you do need a tool to help you with this. There are many free applications that can do this but I usually use ccleaner for the job. They are intuitive and so easy to use. Just be very careful where you download it from. To be on the safe side, always use the play store to get your free application.

Kill resource hogging applications

Sometimes the problem lies with the applications we have downloaded. There are applications that can excessively use the CPU power leaving the resources low for others to use. This will result in the sluggish response to touch or even failure to launch.

But the problem is it is hard to pinpoint which one is a resource hog among other running applications as the running apps can be needed in the operation of the mobile phone. It is not just as easy as clearing out the RAM of ongoing processes only to be disappointed that it does not do any difference or worse.

This problem can be addressed by monitoring the run-away applications that are causing the CPU grind into halt. I use one of these apps called Watchdog Task Manager(Lite Version) to monitor which applications are going out of bounce and notifies user to either kill it or ignore by pressing the whitelist. The applications can also be manually killed by visiting the CPU tab(1) and a long press on the apps reveals the selection actions. The CPU treshold(2) is highly customizable even with the lite version. The default setting is  50% (3) meaning when an app does hugs the 50% CPU power, the watchdog  warns you about it and let you make the necessary decision.


With the phone processes ticked(2), it will also notifies(4) and  shows you what Android system task (5) has been taking much of the processing power. 




The processor can not cope up with applications.

Applications are becoming sophisticated these days, specially gaming. They require much computing power and does not slowdown for slower processor. They just grind to a halt. That's the reason why the moments of characters are just like caught up in a stop and go traffic. The processor tries to manage but it can't, causing the phone to increase it's temperature and the battery being hot to touch. It's not only the battery that is having the fever, the processor as well. At this point, there's nothing I can do but to uninstall the games which I do not play anyway.

Not only games that are the culprit in here, there are also applications although might look like harmless and very light uses the phone's resources to operate, like it uses the GPS monitor, bluetooth, camera etc. If you have this kinds of apps, then be sure to exit them properly, otherwise the resources will still be on and continue to run thus making your phone very slow.
