[X-Men Movies] What was Apocolypse doing in the DOFP timeline?

Surely the collapse of civilisation and a survival of the fittest world for mutant kind is his dream. Was he scares of the Sentinels? Did Sentinels kill him? Should i just accept the timeline is a big mess and roll with it?

I assume he was hiding or still in hibernation. If the Sentinels had gotten him, they would have copied his powers and there would have been no stopping them. Usually, all the other mutants have to team up to stop 1 person with Apocalypse's powers. 10 Sentinels with that power would be unstoppable.
