Batteries only have so many charge cycles, and using these up are cumulative..
so someone who leaves it charged every night for 2 years at 100% is going to burn up battery cycles faster than someone who charges to 100% and unplugs...simple concept
back out of thread...hahaha, you crack me up!! thank you, i needed a laugh today
Again, you're being fairly ridiculous. Apple's expressed lifespan of their iPad batteries is in excess of 1,000 cycles - and that's before dropping to 80% capacity, so actual lifespan is well beyond that. What that means is that you can fully discharge the battery to zero and recharge to 100% daily for nearly three years. So let's say that the trickle charge has a 2% reduction on lifespan (which I seriously doubt) - that amounts to 20 cycles at best.
It may be a fun theoretical exercise for you but there's little to no practical diminution of battery life. Case in point, we have 2 iPad 1s in the house that are still used daily and charged with no real attention to timing or duration. Both have robust battery life, easily more than 80% of "new."
