So would that mean that charging from 90% to 100% ten times would equal one cycle?
Apple has never obfuscated when it comes to their battery guidelines; if it says "charge to 100% and run down completely" it simply means run until it's dead.
I think the one on that iPad link is old, as the one on "the apple battery site"* says:
"you can recharge a lithium-ion polymer battery whenever convenient, without requiring a full charge or discharge cycle"
The one for the iPhone says the 90 percent to 100 percent (I can't type the symbol apparently as the site thinks I'm spamming?) thing under "Standard charging"
But at the bottom it says:
"Lithium-ion polymer batteries need to be used for maximum performance. If you don’t use your device often, be sure to complete a charge cycle at least once a month. Click the links below to add regular reminders to your iCal calendar."
They are giving some conflicting info, as it seems they say to do that only if you don't use your device much.
*Spam filter thinks I'm spamming, so you go to the normal Apple site, and add the slash then you add the word batteries
