If a battery degenerates faster when you charge it often, you would be right.
If it just degenerates at the same rate, regardless if you charge it or not, then I'm right.
The one thing I do know from experience however, is that a battery will degenerate very fast and eventually become dead if you keep it charged all the time OR don't ever charge it (leave it lying around empty).

For a Li-ion battery, it's better to keep it charged all the time, vs leave it empty.
For a NiCd battery, it's better to leave it completely empty, and only charge when empty.
And a battery wears during charging cycles, or fast discharge cycles. The moments when it gets warm.
A battery that runs hot when you charge it, is wearing itself out at a rapid rate.
That's why I'm so much for slow chargers.
Cellphone companies know that a battery generally only gets hot when cells get overcharged. That's why they allow fast charging upto 80%, after which they will continue slow charging.
I prefer the safer, and more sound way of slow charging all the way.
It'll keep the batteries cooler, and live longer.
So, but,
When your battery is used heavily, or charged heavily it wears.
Obviously, if you need your device 4 hours a day, and it lasts for 8 hours a day, at 100% you only charge it once every 2 days,
at 75% you charge it twice every 3 days,
at 50% you charge it every day, essentially doubling the wear on the battery.
