There is an another way.

When you are about to encounter the last battle that the energon bars let you tap in the timer, this leads you to the inventory directly, there tap in any item you want to use and tap "use" in the next prompt, if you want to fill the bars tap twice in the small energon, but this as 123.243.65.226 said make you lose the remain minutes.

But if you use one and then tap in the back button which that leads you to the battle screen and throw the BC and in the next encounter you will enter in the inventory and charge again, you will no lose any remains minutes and you'll get the full bar, but you just went to the inventory twice in a one run.

I hope this help you out. And of course EME (excuse my english)
