Help, something is growing

[Android Central Question]

Using a Redmi 4a AV 7.1.2 N2G47H
There was an OS updata about a week ago, and ever since there has been something leeching space on my phone, I don’t know what it is, I’ve erased all the caches, I’ve moved everything I can to the sd card, but something is taking more and more space and it’s unaccounted for in the files and software.
For example, I clear 200mb of my phone, and overnight after 6-7 hours of not using it, its full and requires me to erase more, at this point there is nothing general more to erase.

I need help.
Thank you

Welcome to Android Central! Caches can build up pretty quickly -- that's what apps and the system use to make their operation smoother and more efficient.

You can use an app like DiskUsage to see a more detailed breakdown of your storage usage.
