What's in Chrome's data? I'm running stock 4.1.2 on a Wolfgang AT-AS43D4 (not rooted). According to DiskUsage, I have about 755 MiB app storage in total, of which I have currently around 100 MiB free space left, so I try to keep the internal storage as empty as possible. 

I see Chrome taking up 94.4 MiB, (134 MiB after the latest update) of which about 24.3 MiB is data (up to 28 MiB by now).

My question is twofold:

What is in there? What does Chrome keep there that's almost over 25 MB big?

How can I selectively clean that? I can delete the data wholesale, but I don't want to. Is there any other way? I tried various options in Chrome, but couldn't find anything useful.



Edited: a previous version of this question mentioned an insufficient memory error. This had little to do with the question; I was conflating RAM and app storage.
Well, &quot;insufficient memory&quot; sounds like you're having problem with your memory(RAM), not your storage space.
DiskUsage is a very good tool, but it only checks disk space and not your memory(RAM) usage.
I just checked out the specs on your phone, and you have 512mb memory(RAM). That's 1/6 of what i have got on my phone, Samsung Galaxy note 3 with 3000mb memory(RAM).
I know it can be confusing with the terms when reviewers and everyone use memory, sdcard, storage and ram very loosely. I use the same terms people use on computers.
My chrome application is currently using 91mb of storagespace as &quot;data&quot;. I believe that chrome is just storing pictures and tempfiles for the open webpages in data, along with your settings, passwords and so on. You can at any time go into the settings on your android menu, choose &quot;applications&quot;, find &quot;chrome&quot; and delete data. Your Chome application will then act like you just installed it. You can try to see if this helps. and it might help for some time.
I think the main problem is that you don't have enough memory(RAM) on your device, and running a almost new os(4.1.2).
If you compare your phone with my previous phone, Samsung galaxy S2 as it was released in 2011 and has twice as much memory(1000mb RAM) as your phone. This phone came with Android 2.3. which does not require as much as newer versions.
I looked up on your os, Android 4.1.x, and the minimum requirements are as following:

7.6.1. Minimum Memory and Storage
&quot;Device implementations MUST have at
least 340MB of memory available to the kernel and userspace. The 340MB
MUST be in addition to any memory dedicated to hardware components
such as radio, video, and so on that is not under the kernel's
control.&quot;

This won't give you much left to other applications.
Well, i think that Chrome also have a share of the blame, as this is no lightweight browser. To solve the problem then I'd first try to set for another browser that is lighter. I would, for example, try &quot;opera browser&quot;, which is designed to use as little data traffic as possible and to run on slow phones. The browser also has a feature that allows when you're phone is asking for a webpage, it will fetch the entire page onto Opera's servers and compress images before the webpage is sent to your phone. This means that the images are not displayed in full quality, but since the screen of a cell phone much smaller than on a pc, its just as well. Since the images is compressed, and use less data traffic, it will also use less space on the cellphone's storage-temp-space. Hopefully, this will solve your &quot;insufficient memory&quot; problem.
I hope this helps :)
