I also had a similia experience recently and noticed than in my 4e adventures there were too many combats that were too long. They were fun battles, even at 1st level, but this became tedious when there were three or four in a row, each lasting an hour or more. And the same over the campaign as 4 became 8 became two dozen long, similiar battles.
So, to spice it up a bit, using advice from here I zeroed in on the resource management and the concept behind each encounter.
The result was one hit minions, two hit minions, standard battles, and multi-tier boss fights. The minions were all sure to have at least standard, if not encounter level, attacks. Each encounter now had their own unique complexities, and the purpose of the encounters shifted focus in the minions battles to the obstacles, effective reource management, and protecting your weak spots. That was a very nice balance, and allowed me to get through many more encounters in a night.
