How did he die, and how powerful was he supposed to be i remember in the anime Shisui stated he was nothing compared to Kagami.

Naruto Wikia:

As an Uchiha, Kagami had very strong chakra. He was also one of the members that were able to awaken his clan's kekkei genkai: the Sharingan, which granted him various advantageous abilities. These included seeing the flow of chakra, the ability to easily recognise genjutsu and different forms of chakra, some predictive capabilities, as well as the ability to copy techniques that the user sees amongst other things. In the anime, his visual prowess was praised by Danzō to be crucial in saving his life many times. Shisui, Kagami's descendant and one of the most powerful Sharingan users of the Uchiha himself, openly admitted his inferiority to his ancestor as a shinobi.[2]

Shuriken to the back, like a fodder.

 

[Titania Erza]

You already answered your own question 'in the anime' it was never said in the manga how strong Kagami is compared to Shisui.

 

[Dantе]

Old age soloed him

 

[lilix]

danzo killed him would not be surprised

 

[KirIwagakure Nin]

He either died of old age or itachi got him in the massacre.but if shisui said kagame is stronger than him its unlikely that itachi at that time would have killed him, obito maybe

 

[Callypigia]

Danzo took his eyes and superglued them to his arm for Izanagi.

 

[Uzumaki Ray]

Kagami was very strong,comparable to prime hiruzen probably while Danzo was fodder before him.Hell Danzo was fodder compared to Shisui and Shisui stated that Kagami was more powerful than him..He probably died in battle or a natural death.Though the latter seems unlikely.

 

[Mr SwizZz]

Probably Danzo suckerpunched him and took his eyes.
