Like the other folks, I've never heard of any such creature! What device do you have? Was 'Device Care' pre-installed on it?
Why are you doing that?
It makes no sense because you shouldn't be doing it.
No, "we" definitely don't keep downloading--or using--them. At best, they're unnecessary; at worst, they're harmful.
If you're continually
needing to clear cache, as in being short on space, using silly 'cleaners' is not the solution. Nor is clearing all your apps' caches manually. The solution depends on the actual problem.
If you're short on space, are there any apps you can live without? Maybe old things you don't really use any more? Or apps, such as credit card or banking apps, that actually aren't necessary, because you can use a browser to access their sites and do whatever you need to do.
What about files you don't need to keep on your device? Photos, documents, whatever--if you can move them to a computer, thumb drive, or cloud drive, that should free up a lot of space.
If none of that solves the problem...I'm guessing it's time for a new device! Android's excellent, built-in method of managing space and memory simply does not lead to the kind of continual housecleaning you're describing. Therefore, I'm guessing that you're either on an older device with limited storage, or you have a lot of stuff on it that you don't
need to keep on it.
I find it hard to believe that a new device would solve the.problem.
My experience has been that the apps that accumulate caches do so relentlessly and continuously until the phone ceases to function.
I have dwindled my cleaning to once a week or so.
But I have found that the more space I leave on a device, the more space the caches will take.
They grow and grow and grow.
They never go away unless I clear them.
And here's the thing- I have never had it happen that the app needed all that crap anyway.
If anything the device and the apps work faster and better.
I really believe that caches are totally worthless.
The vast majority of things that I have found in caches is junk that is better off reloaded anyway.
This is due to the stuff being outdated so soon and yet the old crap is never eliminated (without action on my part).
Why on earth should an app of less than 100MB need 200-300+MB of trash in its cache?
Some apps are worse than that.
It seems like if I had a phone with more memory capacity, that it would all eventually get plugged up with useless nonsense from caches.
Sure, if there was 100GB of internal storage it would take more time to fill it up.
But I still cannot see the benefit of each app packing on MB after MB of junk.
It seems obvious that whatever is there is not really needed- especially when a noticable improvement in device and app performance occurs upon deletion.
Whatever 'benefit' a cache has is easily overridden by this fact alone.
Of course, on a large memory device the effects of gigantic caches will be less, but the vast majority of devices in operation around the world are not such high end devices and the effects of cache clearing are much easier to validate.
This being said, the vast majority of cleaning apps are complete poop.
There are only two that I like, and one that I use.
The rest that I have seen really do more harm than good.
It used to be pretty simple.
Find one with no ads.
Then find one with no ads that doesn't run in the background.
Finally, a cleaner app does not need internet access.
If you find one like that, the odds are in favor of it not doing any harm and only clearing out a bunch of wasted space.
Of course, since Android 6, it has become more difficult for apps to clear the caches of other apps.
With 8 and above there is no built in cache clear either, so on those it must be done by hand- app by app.
On 7 and 8 a cleaner app can only clean part of the caches on the device.
But I generally find that the app I use does clean enough to get results.
I only use the built in cache clear when I really need to, like when the total device cache has reached about ¾ GB or so of crap my cleaner can't get to.
