On several occasions, while traveling, I've forgotten my iPad charger. If I plug the iPad into the iPhone 1A charger, it will charge it even though it says it isn't charging. It just takes twice as along so overnight, it's fully charged. The new iPhone 6 will accept a 2A charger and charge even faster. So I just don't use the 1A charger anymore.

Especially for devices that have sealed-in batteries I'd usually opt to sacrifice some charge capacity in exchange for keeping the battery healthy for more months/years.
It's not worth worrying about. A new battery is about $20-25 for a built in battery and easy to install yourself if you have even moderate mechanical ability. Here are guides and tool sets for pretty much every phone:

It's also become pretty much a cottage industry. Google it for your town and there is undoubtedly a guy who will drive out and do it for you while you wait at you business.
So it's not worth getting nuts about minimizing the charge cycles. After about two years you can do this replacement yourself and get another two years out of a brand new battery.
