Hello @Kayanne and welcome to the community!

After updates, the system will spend some time optimizing the apps to work with the new system files. This might take up to a couple of days where you can experience lag, battery drain, or excessive heat.

If you think that this issue is taking longer than expected, then I'd suggest that you do a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable. 

Don't forget to backup using Xperia Companion before proceeding with the repair process.

go to settings, memory and look at the total memory figure.  My guess is it will say 883MB

If that is the case, your phone has lost 1GB of ram, like many other m4 aqua phones have.

SONY: We want our phones fixed!!!!  The problem is not software or firmware, it IS hardware.

Many M4 Aqua user don't know about this android Marshmallow when talking about ram..

It shouldn't use over a GB of RAM though.  It stands to reason it will use more storage space, which is why you are left with only a couple of GB for APPs.

There seems to be a lot of misunderstanding over What RAM actually is and what it does.  RAM is used to store frequently used data, and thus make programs or APPs open quickly.  The APP itself is not stored on the actual RAM.

A modern smartphone is similar to a computer.  You have a processor, RAM and Storage/hard drive.

The reason for these phones going slow is due to one of the RAM modules failing, but Sony refuse to acknowledge this.  It isn't rocket science, it is basic computer theory.  Take an old computer, remove half the RAM and just see how much it slows the performance. It'll behave just like a would with half it's original RAM, i.e. it will still work, just very slowly.
