20,000 / 3650 > 5 years.

But you didn't factor in that at some point, the battery won't last as long before needing to be charged. It will still last long enough, but not as long and need more charging then when it was new.
And how do you know it will last 40 hours of being used before needing to be charged? We don't not what apps will be used and how processor/screen intensive they will be. And then we also don't know how bright the lights will be when they are on or how often the lights will be on. There's a lot of unknowns and I don't think the batter will last past 5 years with that much intensive use.
