Yes, the Voyage's battery will last longer since you won't be cycling every 12 days in this scenario. But the general thing I'm pointing out is that for someone with a lighter volume of consistent reading will get quite a bit of use out of just the internal battery. Enough that even if you read for 2 hours a day, every day, without fail, you are still looking at 2.5 years before things get wonky. Which isn't great, but isn't terrible for such a small battery.

Thank you for the numbers. The only thing I'll add is that after those three hundred cycles, the battery capacity has gone from 6 hours to 5.1 hours.
And if you read 5 hours a day:
After 1 year: 332 cycles, 5 hours of capacity left
After 2 years: 749 cycles, 3.8 hours of capacity left
After 3 years: 1407 cycles, 1.8 hours of capacity left
P.S. when I've mentioned cycles in my posts, I've been refering to "full" charge cycles, i.e. 1 X 100%, or 2 * 50%, or 3 * 33%, ...
