Yes, the cache gets stored separately somewhere and a cleaning app can’t do the job. Here’s what you should do instead.

Cache accumulation not only causes precious memory space in your Android phones to get crammed up, but cache build-up also causes the internet speed of your Android phones to take a sudden drop.

When I bought my first phone I was, like others, also tempted to stock it up with many fancy apps I could get my hands on for free.

And a memory cleaner app was always a top priority.

But the cache doesn’t go away like that. What they do is remove the temporary files, thumbnails, and other junk files.

But the cache that your browsing apps collect i.e. Opera Mini, YouTube, Reddit, LinkedIn, Gmail, etc. do not go anywhere unless you remove them yourself, manually.

What is cache?

Many apps create small files as you use them where they store your data based on your usage so that when the next time you use those same apps, you get quicker turnarounds without re-loading the same function.

Let’s say you went online to read a manga (Japanese comic) and you are checking its pages one after another to decide whether you want to give it a shot or not.

Eventually, you decide yes, you are interested. So, you push the back button to go back to page 1.

Did you notice something?

When turning the pages the first time around, your phone had to load up images.

But now that you are going back to previous pages, it’s not loading, you just directly land on the image without any loading time.

That’s cache in action.

How to remove cache from your Android devices?

My advice to you is to never bother with memory cleaner apps and especially their RAM-boosting functions.

Those are counterproductive as they hurt your Android phone’s health.

The big bad cache needs to be removed manually every month or so.

Here’s how you can properly delete cache files:

· Open up the app tray and go to Settings

· Select App Management

· Select App List

· Select the app that you think must be collecting a lot of cache, in my case, it is Opera Browser

· Tap on Storage Usage

· You can see 360MB of my memory is being used by opera as cache memory, tap on Clear Cache

· And that’s how you actually remove the cache.

Go to every app on your phone that uses goes online to function and remove each app’s cache individually.

Older versions of android phones had one simple button to remove all cache memory.

But, I believe individual cache removal is way much better.

Knowledge is power. I’ll keep posting more practical entries on my blog about tech-related solutions.

Thanks for your time.
