This is a neat trick I found out a while ago but forgot to share with you all, so here it is now. If you use shield boosters, once your shields are down, deactivate all of them. The red circle showing the recharge progress will fill up faster, and your shields will be back up sooner! As soon as they're up, you can reactivate all your shield boosters.
If you need proof, just wait a while when your shields are restoring to let the gauge build up a little, then look at the gauge as you switch off your boosters. It will suddenly jump up a few squares.
