Help The old insufficient storage issue

Can someone actually explain why the insufficient space problem happens, even when there is clearly plenty of storage space available, because it's really doing my head in! I've tried all the usual fixes short of the ones that require rooting my phone, which I'm reluctant to do, to no avail. It's not a capacious device, with only 2Gb of internal storage and just 756Mb for apps internally. But when it's telling me that I still have 1.84Gb available internally and 80+ Mb free for installing apps why does a 10Mb update fail?!
I'm not expecting a resolution because I don't think there is one(!) I just want to understand what it is about Android that is so intolerant of limited (but sufficient) storage capacity. One theory I had was that it is actually something in the individual apps' apk files which looks for space beyond what's actually needed. Because I can usually apply 30+ Mb updates to Firefox, whereas a tiny 2 or 3 Mb app sometimes won't update. Can anybody confirm or refute that? My device is a Huawei Ascend G300 with (as I said) 2Gb internal storage, 387Mb RAM and an 8Gb SD card.
For background, I've pared my installed apps down to a minimum and moved them onto the SD card where possible, and I've cleared out caches. As I said, I don't really want to take that next step of rooting the device, despite being a techie in my day-job, and knowing my way around Unix & Linux systems (I spent about 15 years supporting a couple Solaris servers and now have responsibility for a range of Ubuntu boxes).
Thanks.

Apk files are basically zips.

Storage Truth and RAM Truth download as an apk of about a half MB each but double in size when installed.

Then comes data and cache for most every app.

Google Maps is a 13 MB apk but right now the app is 23 MB, and it's using over 15 MB for data and over 44 MB for cache on my phone.

Started out as 13, now 83 MB.

A non-root move of the app to the sd card doesn't help a lot - the data and cache are private so they stay in the /data partition.

Add to that, during an app installation, the Play Store is going to start in temporary storage in the /cache partition, expand things and copy to /data.

That's why app downloads are not what they seem.

Anyway, try the link for some decent tools for visibility.

Hope this helps!
