The 1,200 – 1,500 cycles is if you discharge to 50% and then charge back to 100%. As a "charge cycle" is from whatever your low point is to 100%. So only letting your phone go to 50% is a good idea. But keeping it at 50% just seems silly.
Looking through that article's comments, theres alot of confusion about what capacity to keep your battery at. There seems to be data to say that letting the phone go to 50% then charging gives you less cycles but more overall usability.
I'm going to have to read that article because last I checked, the cycle count is in regards to a full 100% charge.
[Day 1 - 50%, Day 2 - 50%(1 cycle)] [Day 3 - 25%, Day 4 - 25%, Day 5 25%, Day 6 - 25%(1 cycle)]
