I have the same problem but when I looked in achievements on trophys or collectibles can't remember exactly which, they are ticked off so I just sold or destroyed them

From my understanding, consoles have no "Use" feature and the items automatically count towards achievements.

You don't have to use them for them to count towards your achievement, you just have to obtain them. If you do wish to use them to see what they do, you can assign it to your hotbar (the same way as assigning potions). Some of them do some fun things, but they aren't really meant to be terribly useful, just fun. Deleting them will not mess up your achievement, as once it enters your inventory it counts. The same goes for collecting the rare fish in each zone. Given the amount of collectibles in the game, they weren't going to make it so you had no choice but to fill your valuable inventory and bank slots with them. So don't worry about deleting them. I've deleted almost every one I've gotten and I still have some of the achievements (I still have some more collectibles to find to get the rest).

As for the Skyrim achievement, in there you essentially get unlimited chest space. You could set aside a chest in one of your houses just for the Daedric Artifacts, and once you get 15 you can pull them all out into your inventory, get the achievement, and get rid of them. That way you don't have to keep carrying them and wasting carry capacity.

Though they may both be listed as 'Trophy", trophies and collectibles are not the same. Trophies that you get as the result of some quest cannot be consumed. They stay in your inventory until you get rid of it. They also have no achievements related to them. And they can be used in Quick Slots or however they are triggered on console, giving some minor benefit or graphic effect. Collectibles, on the other hand, are rare items that drop from specific creatures. They can be consumed, at least on the PC, they are listed in your journal achievement tab under Trophy.

It seems that unlike the PC, they automatically register in your achievements when they go in your inventory. This has been a big question. It would be great if a console player can confirm that they register as soon as you pick them up. BTW, there are dyes that unlock when a group of collectibles is completed.
