According with comments read in that forum:
Implement CUE on APE files
Solves some problems of consumption of battery

It hasn't been solved the stutter issue
Applying it doesn't delete data from flash memory (tested over version T2.004.3)
Concerning implementation of CUE files on APE, which I've tested,

It works splitting files and playing them.

No artist name shown in lists by Artist or Album, appears as "unknown"

Show Artist, Album, Title when played

Plays songs in
alphabetical order

Sound is great as supposed to be for a lossless format

I haven't been able to display cover art
To make it work CUE file was put together with APE file with exactly the same name.
In my case I put them in structure MUSIC\ARTIST\ALBUM which is my normal structure.
