When a god loses their power, or at least completely ,... they ... are ... dead.
Tuska is a mindless beast that is mostly dead. Only the residual anima of all the worlds she consumed is still coursing thru her. It's not like it is keeping her alive. (Think like the Golden Throne in Warhammer 40k that is keeping the Emperor of Mankind "alive" ... just without the whole 'most powerful psychic in the galaxy' and the warp being in play).
Tuska's cause of death was being repeatedly stabbed by an anima energized weapon. The spears used in WE3 were basically an attempt to recreate the God Sword. They weren't a perfect attempt, thus why it took LOTS of pokes of doom and LOTS of anima to leave her mostly dead.
Zaros is stated as having the ability to escape death (of sorts). So when Zammy began draining Zaros' power, Zaros was able to do a fast jump from his crystalized form he had (at the time) and escape as a ball of energy.
It took THOUSANDS of years for him to regain the majority of his energy (that's assuming you didn't give him a light anima shell). Even then, he may be wiser, but he might still be weaker than his pre-God Wars form.
Zamorak and Saradomin were simply a case of 2 beings doing a continuous beam of energy at each other and being fed lots more raw energies by followers (or whatever you want to call it). Saradomin got more and then hit Zamorak. You could say that Zammy lost a tier because he was trying to pump in more of his own energy to keep up, and still lost.
After BatB, the devs stated that when a god dies, if another god killed them, they have the option to absorb their energy. Armadyl didn't do that. So Bandos' energy took a page from other gods, and yes, leaked out. Given that he lost a tier from his attempt to make the Amulet for his Chosen Commander, and then the Yubiusk Portal, there might not have been too much to absorb.
