Re-calibrating Prime's Battery?

[TheLastMillennial]

Thanks for clearing that up eried! I completely forgot to add that the battery wasn't in the best health when I got it. I thought the issue would be because of the bigger battery since my TI-84 Plus CE'S battery is in poor health but it rarely ever underestimates the level. I guess there's something else going on instead.

Have you considered redoing that test for the G2? It would be neat to see how the new battery and CPU effect the battery life!
